Nuomici

Summary:

The Senju brothers were locked in a room where they had to make a choice. For the sake of the new Konoha, they had to choose to harm Hashirama's body or "develop" Tobirama.

Room9 Settings

Chapter 1

1.
Hashirama Senju woke up.

He was surprised at the soreness in his head. For him, who always had good sleep quality, this feeling of lightheadedness was not as severe as when he lost too much blood.

Although Konoha had just been established, there were many things to deal with, but thank God, his brother was a bit of a genius in general affairs.
With Tobirama by his side, many things became easier.

Um?

Hashirama suddenly found himself in a room he had never seen before,
and Tobirama, who was still unconscious, was lying next to him.

2.
Tobirama showed no sign of waking up. Hashirama looked at his brother for a while and noticed a very fine scratch on his chin.

It's really hard to find, after all, he has those three eye-catching facial lines.
Hashirama held his chin and looked at his brother, trying to find something unfamiliar on that familiar face.

After Tobirama became an adult, or even earlier, he seemed to have never looked at his brother's face carefully again. They spent more time together in the study. On the battlefield, Tobirama liked to stand behind him, and was very alert even when he was asleep.

Now he was lying there, wearing the Anbu uniform he had just gotten, and it seemed like he wouldn't wake up for a while.

Ah, if you observe so carefully, Tobirama's skin is really good and very white. Come to think of it, he seems to be the whitest among his brothers.

So the dark circles under his eyes are clearly visible... Is it because there are too many tasks thrown at him from time to time?

The First Hokage felt guilty for half a second and decided to put this question aside - there are usually two outcomes for problems that are put aside: one, the forgotten problem is no longer a problem; two, Tobirama will consider it anyway.

Senju Hashirama was daydreaming like this for a while, and suddenly he met a pair of red eyes.

Hashirama: "..."
Tobirama: "..."

Hashirama smiled happily: "You're awake!"

Tobirama sat up: "Brother...what are you doing...wait, where is this?"

"I don't know either," Hashirama said honestly, "We woke up here, and I had a headache just now, as if I hadn't slept for three days."

Tobirama turned over and saw a completely unfamiliar room in front of him. The colors were warm and the space was spacious. Soft sunlight shone in from the window, like the warm light near dusk.

"You've been awake for so long, why didn't you wake me up?"

His brother smiled and said, "I saw that you were sleeping soundly, so I wanted you to sleep a little longer."

Tobirama took a deep breath, "I can't use chakra anymore."

Hashirama turned his hand over and discovered this as well: "Me too."

Not only that, he could feel that almost all of his body's abilities were sealed. He could not communicate with any element and might become even more fragile than a Genin.

They were trapped.

Hashirama's expression became serious. This was a situation they had never encountered before. Moreover, Konoha at this moment was like a newborn baby. The war outside had not yet completely subsided. If the two of them were missing at the same time and could not return as soon as possible...

Not sure what will happen.

Tobirama has begun to check the entire room. There is nothing special, just an oversized bed, and a TV screen on the opposite wall - this is even a new thing he just invented two days ago, and it is not even popular in the village. There is a bookshelf and a dining table with two chairs next to it, and there is also a terrace full of green plants - Tobirama walked over to take a look and found that everything from the green plants to the sunny lawn outside the window is fake, made of plastic and projected.

The room is completely sealed and air exchange depends entirely on the ventilation system.

There was a door next to the terrace. Tobirama leaned against it and listened for a while, then opened it cautiously and found a bathroom with all kinds of supplies, and even a jacuzzi.

"Who could have gotten us here, Uchiha?"

Hashirama sighed, "I think Madara would prefer a frontal battle."

He followed Tobirama and tried hard, but whether it was the wall-mounted TV, the large screen embedded in the balcony, or the other door that might lead out of the room, it was completely impossible to destroy it by violence.

The force from kicking the door also caused his foot to rebound, which was quite painful.

Finally, the two brothers had no choice but to return to the bed.

The light on the TV flickered, and Hashirama looked at Tobirama: "How about turning it on?"

Tobirama walked over and pressed the button hard.

The TV lit up, and a line of beautiful small words appeared on the screen.

【Welcome to participate in the experiment, thank you for your dedication. During this period, please actively comply with the following rules. 】

"What is that?" Hashirama frowned. This room gave him an increasingly bad feeling. The word "experiment" also sounded full of unfriendly evil.

"If we don't cooperate, what can he do? Will he lock us up forever?"

"I'm afraid that's possible."

There is no need for any attack. If this place can really deprive them of their chakra forever, as long as they don't provide food, Konoha will lose their Hokage in a few days.

[In order to ensure the smooth progress of the experiment, the two of you have been banned from having special abilities. Please don't worry. When you leave the room, everything you have taken away will be returned in full.]

"Such a condescending tone," Tobirama muttered, "is really annoying."

Hashirama was puzzled: "Is there?"

[The daily options will be delivered with breakfast. Please choose one and complete it before 24:00 on the same day. Each completed item will get 10 points. When the points accumulate to 100, the experiment ends. Points can be exchanged for special items or services. Three meals a day are provided free of charge by our party. Please don't worry about dirtying the room - the room setting is reset at 24:00 every day. Please note: the self-cleaning setting does not include the experimenter. If necessary, please clean it yourself. ]

[Note: If any of the experimenters dies, the experiment will end immediately.]

Tobirama's back straightened, and Hashirama could see from behind him that he seemed to be irritated by something in those words, his jaw was tense and his face was livid.

"No matter when, no matter——"

Tobirama turned around and stared at his brother with unprecedented gritted teeth:

"We can do it," he said quickly. "This so-called experiment, or anything like that, you'll never be able to open the room that way."

What?

Hashirama was puzzled for a moment, and his eyes could not help but turn to the words again. After thinking for two seconds, he suddenly realized.

Tobirama was right! If there were options that they were completely unable to complete, for the sake of Konoha, they could not be trapped here forever.

In that case, as long as one party dies, it will be enough.

Hashirama thought calmly - of course he cherished his life, but if there was no other way, right? This was a prerequisite. When there was no other way, in order to choose a path that was better for everyone, nothing could be sacrificed.

The bright red color suddenly jumped into his field of vision, very close.

It was Tobirama, the younger of the brothers, who was twisting his older brother's shoulders with both hands with a force that could not be ignored.

"Don't even think about it," Tobirama said, "I won't let that happen again."

His pupils and the bright red wrinkles on his face seemed to be burning at the same time, and Hashirama thought of the battle not long ago.
That was the first time that their lives and deaths were put on the balance of choice together. He made the decision himself, but what about Tobirama?

Hashirama thought silently.

If he had to choose between the two of them, would he even bother thinking about it?
Before he closed his eyes completely, he would never allow anything to happen to Tobirama.

"I'm telling you, brother," Tobirama said, looking at Hashirama with an anxious and fierce look, "If you dare to end the experiment in this way, I will never leave alone."

Hashirama realized that he wasn't kidding.

Chapter 2

3.
They stood in front of the screen in a tense atmosphere until the annoying "other note" disappeared and today's options slowly emerged.

[Day 1:
A. Experimenter B cuts a 2cm long and 1cm deep wound on the inside of experimenter A's arm.
B. Ask experimenter A and experimenter B to kiss (Note: 1. Duration ≥ 120s. 2. The tongue and lips must maintain contact at the same time. 3. The degree of body fluid exchange is based on drawing. 4. The above three points must be met at the same time, otherwise it will be judged as a failure.)

Please check the mark on the back of the neck for the experimenter's number. 】

"......？"

The two brothers fell silent at the same time.

"What on earth is this," Hashirama said in confusion, "Is this a prank?"

The two of them were just facing a formidable enemy - considering the content in the "additional note", it is easy to associate it with a place like a colosseum, and the task should be to let them kill each other or something...so what exactly is the strange thing about the second option.

Tobirama held the back of his brother's neck: "You are 'A'."

The small, pitch-black letter "grew" on Hashirama's skin like some kind of brand, and felt slightly raised to the touch.

"It itches."

Hashirama said, turning sideways, pulling out a kunai from somewhere, and said in a relaxed tone: "Then let's get started."

Tobirama stared at the thing, his face darkening slightly as if he remembered something unpleasant.

But he did not raise any objections.
The option required a wound 2cm long and 1cm deep, which was no different from a mosquito bite to them. Especially considering the cells of Hashirama, the wound would not cause as much trouble as a mosquito bite.

Although he also wanted to try it, if he didn't choose either option, what could this room do to them?

When Tobirama passed the kunai, they both tacitly ignored option B. It was too much of a bad idea for two men, or for brothers.

2cm long and 1cm deep, Tobirama accurately cut Hashirama's skin and waited for the scarlet wound to heal quickly in front of him.

But no.

The TV made a cheerful sound, reminding them that they had completed Task A of the first day. At the same time, hot meals appeared on the dining table, emitting an enticing aroma.

Tobirama stared at the scratch that was still bleeding and felt a sharp chill running up his spine.

"Your immortal body...is ineffective."

Hashirama seemed to be thinking about something. He used his other hand to pick up a little of his own blood and smelled it carefully.

"Right," he announced. "I guess that's what the rules say. Our special abilities are blocked."

"This room makes us easy to kill."

Chapter 3

4.
The rest of the day was a bit silent. They looked through the "Experimental Details" that came with the meal after they completed the options, and came up with a very bad estimate for the next few days.

"No doubt these missions will become increasingly excessive," Tobirama said, "especially since you can no longer recover quickly."

Hashirama's wound was roughly bandaged with a piece of cloth torn from his clothes. It had stopped bleeding, but he couldn't use force, as it would easily tear if he did.

Hashirama placed his arms flat on his legs. "Actually, I was wondering, what if we don't choose? Will we be punished directly, or will we be deducted points?"

They got the precious 10 points today. If nothing goes wrong, they can complete the ten-day task and get out of here.

This is also the question that Tobirama has thought about.

"But we can't stay at home forever. We still need points," Hashirama sighed, "I wonder how Konoha is doing now."

They temporarily diverted their attention from the strange room and discussed the development of the village for a while. Until midnight, the dirty dishes and wrinkled sheets disappeared together, replaced by another set of clean and new ones.

Apparently, this is the so-called "self-cleaning function" of the room.

I don't know when I fell asleep, and the next day it was Tobirama who woke up first. He saw breakfast already laid out on the dining table, and on the TV screen, there were messages about today's mission.

[Day 2:
A. Ask experimenter B to collect 3000 ml of blood from experimenter
A. B. Ask experimenter B to insert a prop into the anus while giving experimenter A oral sex until he ejaculates (Note: 1. After experimenter A ejaculates, experimenter B needs to open his mouth to perform until the semen drips. 2. After experimenter B finishes the performance, please swallow the remaining semen, which must not be less than two-thirds of the total amount. 3. Please complete the content of item B on the previous day first. 4. The above three points must be met at the same time, otherwise it will be judged as a failure). ]

Tobirama stared at the lines of words, and the strong sense of absurdity made him speechless for a moment.

But, option A cannot be chosen today. 3000ml... This means draining half of Hashirama's fluids. Now that the Sage Body is ineffective, his life will inevitably be in danger.

"Hmm..."

At this time, Hashirama let out a vague mumble and woke up.

Tobirama was sitting on the bed with his back to him, his back was a little stiff, Hashirama stretched and said, "So, what are the options for today?"

The words jumped into his eyes.

Hashirama was strangely silent for a while, and the atmosphere between them was even a little awkward.

"How about..." When his brother mentioned it weakly, "In order for the experiment to go smoothly, this place won't let us die easily, right? As long as we can hold on for ten days, I will be able to recover once I get out..."

"Shut up! Don't even think about it!"

The aroma of ramen continued to enter the noses of the two people, but no one had an appetite to enjoy breakfast.

Their eyes met in the air, then bounced apart. At the same time, the words on the TV seemed like red-hot charcoal, as if one would be burned if they just looked at it.

Hashirama tried hard to forget those evil descriptions, but by coincidence - it was really just a coincidence, his eyes, which had nowhere else to go, fell on Tobirama's lips, which were not rosy and soft, but looked a little sharp.

Tobirama's lips pursed tighter.

This is impossible, Hashirama thought. They are brothers, how could they do such a thing?
Even if it wasn't possible, he would not let another person fall into such a humiliating situation, especially because of him.

Hashirama took a deep breath, solidified his thoughts, and patted his brother's shoulder.

"Let's eat first."

"us......"

"We have no choice," Hashirama concluded firmly, "This house, no matter what it wants to do, if it thinks it can toy with us without any bottom line, then it is wrong."

"If they must die, the people of the Senju family will not die on their knees in such an ugly manner."

Tobirama's eyelashes trembled and he lowered his eyes.

5.
This day passed unusually slowly. They seldom spoke, but they did not miss any meals. They were in the best condition, waiting for time to pass by every second.

Tobirama was clearly having some doubts, and by the evening he began to pace around the room, either suppressing his gaze or looking at Hashirama's calm face.

Actually, it won't be a big deal.

Tobirama couldn't help but think so. After these two days, they could see that there was a certain pattern in options AB.
The missions against Hashirama were mainly physical harm, and they were becoming more and more dangerous, but the missions against him were just some...

It was just some mental humiliation, Tobirama thought, and there would be no danger to his life.

Of course, he would never want to make a fool of himself in front of his brother, but what if he had to choose?

Compared to Hashirama's life, these things are too insignificant.

But Hashirama would not agree. Tobirama knew this. To put it bluntly, they were gambling now, hoping that the punishment brought by passive resistance experiment would be acceptable. But that would only treat the symptoms, not the root cause. They could not stay here forever, nor could they die for this ridiculous reason.

Konoha needs Hashirama, and the whole world outside needs Hashirama.

"Why don't you sit down?" Hashirama said gently, "At least save some energy. You're going to make me dizzy."

Tobirama stopped walking, and after a while, he sat back in his chair obediently.
Hashirama was right, even though they didn't like to leave their future to an unpredictable fate, they should at least save a little more energy to deal with it.

As the clock approaches midnight, the atmosphere becomes tense. They stare at the clock on the wall, the second hand ticking slowly. Thirty seconds, twenty seconds, ten seconds—

Seven, five, two, one.

There was absolutely no warning, just like a paused animation being played. The moment the second hand returned to zero, Hashirama, who had just been sitting upright, suddenly spat out a large mouthful of blood. He could no longer support his body and slid off the chair. The wound that had almost healed yesterday burst open, and countless amounts of blood gushed out!

They truly had no power to resist. The First Hokage, who was famous for his fighting ability, fell down powerlessly and could only let the life and blood slip out of his body, while his scheming brother stood by and could do nothing.

"Brother!!"

Tobirama jumped up suddenly. He caught a glimpse of a dangerous red light flashing on the TV screen. A huge "Warning! Warning!" was constantly jumping, accompanied by the sound of sirens, irritating people's eardrums. The words that appeared on it seemed to be stained with blood.

[Detected violation X1, implemented penalty: unconditionally execute option A. The option
can be changed. If you need to change the option, please execute it directly. The penalty will end after option B is executed.]

What......

Tobirama's eyes were red with anger. This was not a choice at all - what was there to choose from?

He was willing to pay any price as long as he could save Hashirama.

"Brother!"
Tobirama knelt down. The lower half of Hashirama's face was covered with the blood he had vomited. His eyes were beginning to become a little unfocused, but he was still trying to comfort him.

"This is at least better than, than you coming to get it..."

"Shut up."
Tobirama murmured, pulling up Hashirama's upper body as quickly as possible and kissing him without any doubt.

Hashirama's eyes widened.

First, we need to execute option B from yesterday. What were the requirements?
Tobirama quickly recalled that he had no experience in kissing, but fortunately the task requirements were very detailed: first the time, then the contact area, and then...

He held the back of Hashirama's head, letting his limp body lean against his arms, and forced open his teeth, allowing his tongue to touch his brother's.

Amid the thick smell of blood, the unprecedented soft and smooth touch seemed to burn from the tip of his tongue. Tobirama's knees were numb and he had no mind to feel it, but the physiological reaction brought about by the deep contact was something he could not ignore.

That wonderful feeling was like electricity and fire - why did kissing his brother bring about such a reaction?

Tobirama had no time to think. He tried his best to carry out the task according to his own understanding, the contact of lips and tongue, and then the exchange of body fluids, until it was done by a thread.

Even at this moment he couldn't help but blush a little. How could he draw the silk... stir it?

"Well, the door..."

Hashirama tried to speak, but the last thing Tobirama wanted to hear right now was his brother's voice, and that made his efforts to keep his lips and tongue in contact mode that much more difficult.

In order to prevent Hashirama from making any noise, Tobirama made them fit a little more tightly.

He began to use his tongue to stir his brother's mouth without any instruction. He didn't know the method, but he did achieve an "exchange of body fluids". The temperature between them was rising and they made "tsk tsk" sounds when they kissed.

During this process, Hashirama was even spitting out blood. The taste on the tip of his tongue made Tobirama's scalp numb, which reminded him of the urgency of time all the time. If he couldn't complete the task as quickly as possible, Hashirama might lose excessive blood at any time.

After a long 120 seconds, they separated. Tobirama's efforts were effective. There was a soft "pop" sound as he slowly left his brother's lips. Blood and saliva made a mess of both of them. The pink silver thread stuck between his lips and teeth, trembling, fragile and shameful.

Tobirama noticed with surprise that the speed at which Hashirama was vomiting blood seemed to have slowed down, and the wound on his arm had healed.

He makes things work!

Hashirama was truly shocked by his brother's bold move. He had completely lost control just now, and Tobirama actually acted on his own.

"No," Hashirama panted heavily. The blood loss made his eyes go black and his body felt cold, but his expression was more serious than ever. "No, Tobirama, I can't do those things to you."

The relationship between the two Hokage brothers is very delicate. People who are familiar with them know that the elder brother, who is older and more powerful, is gentle and unremarkable, while in most cases, the younger brother seems to be the one who makes the decisions.

But only a smaller number of people understood that Hashirama was always the absolute dominant one in this relationship. He might usually just be very indulgent towards his beloved younger brother, but when he really decided on something, Tobirama would never resist.

But this time, the formula didn't work.

Tobirama avoided his brother's eyes, he lowered his head, and Hashirama could only see the lower half of his face. His brother said nothing, stubbornly put him on the bed and sat against the head of the bed.

"Tobirama!"

"I won't let you die," Tobirama picked up the "props" provided by the room from the table, still refusing to look at me, and said in a low but firm voice, "It's nothing, brother."

6.
That's definitely not "nothing".

Tobirama took a deep breath and quickly took off his pants, including his underwear. Facing Hashirama, who was unable to move for a moment, he knelt down with his thighs spread, holding the vibrator in one hand and reaching behind him with the other hand, finding the position and thrusting it in without hesitation.

"......"

It was really painful. The random insertion made the parts that shouldn't have been able to bear it tense up their defenses. Tobirama's face was pale, but he didn't reveal a sound. He pushed his fingers forward with difficulty as his waist and abdomen trembled slightly.

The rough invasion tore the tender flesh, and Tobirama felt the blood and was slightly relieved. With the lubricant, his movements gradually became smoother.

He tried not to think about his current appearance, nor to look at Hashirama who was still vomiting blood from time to time. He just treated this as an absurd task...

Fortunately, the vibrator was not too big. Tobirama silently estimated the size, pulled out his finger at the right time, and forced it in.

The vibrator got stuck slightly when entering the thickest part, then slid in smoothly. The cold and hard gelatinous touch made Tobirama tremble. He didn't care about anything else. After making sure it wouldn't fall out again, he bent over Hashirama and pulled down his pants.

Perhaps realizing that his brother was determined this time, Hashirama did not say anything to stop him, but that was really...

Hashirama tried his best to maintain his sitting position, his proud brother kneeling in front of him in an extremely shameful posture, his buttocks raised, blood flowing down his open thighs. His waist slumped down obediently, and he was hit in the face by the penis that popped out unexpectedly, but he quickly regained his composure and opened his mouth to take it in.

Hashirama gritted his teeth and held back a sigh. It was too sinful.

But the feeling of comfort of having his lower body wrapped in a soft and wet mouth was so obvious that it could not be ignored, especially when it was his younger brother, Tobirama Senju, and it was Tobirama's head buried between his legs, rising and falling, serving that thing flatteringly, his silver-white hair rubbing against his lower abdomen, bringing a slight itch.

Tobirama is very handsome, and although he has a bad temper, he is still very attractive.
Hashirama certainly knows that his brother is very good, smart, handsome, and resourceful. They have always been the closest people in the world.

But even if he killed him, the former Hashirama would never have thought that there would come a day when they would come into contact in this way.

Tobirama's tongue was eagerly pleasing his erect penis. This guy, who had always been a good student, was a little clumsy at this moment, and sometimes he couldn't control his teeth, causing slight pain, but that was of course nothing. Hashirama was always looking at the back of Tobirama's head. He thought about it and gently stroked the silver hair with his hand.

Tobirama shuddered uncontrollably, his mouth suddenly tightening.

Both of them groaned at the same time. Hashirama's brain went blank for a moment due to the squeeze, while Tobirama felt that the vibrator that had been quietly staying in his butt since it was inserted suddenly vibrated violently!

Needle-like pleasure came from places he had never expected, rushing up his spine like an electric shock, and Tobirama's legs were so weak that he could hardly kneel. He still had Hashirama's enlarged penis in his mouth, his cheeks were heating up, and he could hardly breathe.

"Tobirama?" The intervals between Hashirama's vomiting blood became longer. He regained some strength and asked worriedly, "What's wrong with you?"

Then he saw the line extending from Tobirama's anus and hanging on the bed. The line was jumping violently, and it was not difficult to imagine what kind of carnival was going on at the other end.

Hashirama frowned and raised his hand to help him pull it out.

"...Don't," Tobirama panted and raised his head. The thick cock slipped out of his mouth. He eagerly pressed down Hashirama's hand and finally looked up at him, "Let it, let it stay."

He didn't dare to gamble anymore, and didn't dare to have even a little bit of luck. What if he took out that thing and the mission was judged as a failure?

Tobirama bent down with difficulty, trying his best to ignore the crazy pleasure, and continued to hold Hashirama's penis in his mouth, sucking and licking it like a piece of candy.

Hashirama closed his eyes and clenched his teeth tightly. After a while, he spoke with difficulty: "You can, ahem, lick it - the very top."

It took all his strength to say this, but as long as he could complete this damn task quickly...

Tobirama was stunned, then obediently pulled out and licked the most sensitive tip with his tongue.

An unknown amount of time had passed, but when Hashirama felt his back tighten, he instinctively wanted to push his brother away, but Tobirama was obviously relieved and grabbed his hand, taking the penis even deeper into his mouth, and using his soft and tight throat to finally squeeze the glans that was swollen to the limit.

Hashirama ejaculated, and his brother swallowed all the white liquid into his mouth without leaving a drop. His expression was as serious as if he was completing a spell experiment, if you ignore his red cheeks and watery eyes.

Tobirama raised his head from between Hashirama's legs, blinking slowly, still kneeling with his legs apart, his mouth slightly open.

It was filled with sticky white semen, which contrasted sharply with his lips that had been rubbed into bright red. The liquid slowly spread toward his lips. Tobirama did not move. In fact, his mind was already a white mist. The vibrator was still torturing him in his anus, bringing more intense and unbearable stimulation every minute and every second.

But he must, must control himself. Tobirama always kept in mind that this was just a "display" session, and the amount of semen overflowing from the mouth could not be more than one third.

Finally, the turbid liquid overflowed from the corners of his lips, slid across his ravaged plump lips, and dripped onto his black high-necked combat uniform.

Tobirama tried hard to swallow the remaining semen. The strange taste and texture almost made him breathless, but the good news was that the blood finally stopped flowing out of Hashirama's mouth.

A pleasant "ding dong" sound came from the direction of the TV, indicating that the task was completed.

Tobirama suddenly went limp and couldn't move for a moment. The overly intense stimulation in his lower body surged out doubly when he suddenly relaxed, making his knees weak, his tailbone numb, even his pubic bone trembling constantly, and his eyes went dark.

He didn't even have the strength to turn over and pull the thing out.

A somewhat cold hand was placed on Tobirama's waist.

It was the pale-faced Hashirama. His brother's chin was still covered in blood, but he gently turned him over, spread his stiffly closed legs, pulled the line, and with a slight "pop" sound, ended this long and shameful task.

7.
Tobirama was sleeping soundly.

The exercise before going to bed undoubtedly consumed too much physical energy. After confirming that Hashirama was no longer vomiting blood, he fell asleep without any resistance.

On the contrary, Hashirama couldn't sleep.
The low blood pressure caused by excessive blood loss made his sympathetic nervous system defensively excited. He lay on the bed, looking at the dark ceiling, feeling confused.

Senju Hashirama considers himself to be a generous person, which is very unusual for him.

However, in such a closed environment, Tobirama was lying next to him. He could feel the arc of his brother's body pressing down on the soft bed, hear his breathing, and feel a little familiar body temperature.

Just a moment ago, those breaths and body temperatures were entangled in his lower abdomen...

Hashirama blinked hard to drive those images out of his mind.

He shouldn't always think about these things. The new Hokage felt a little embarrassed and guilty. Tobirama tried to save him, and his brother was hurt in order to save him, but he was "recalling" the hurt itself.

This is totally wrong.

Hashirama rolled over, studying his brother's profile in the darkness.

They spent a day verifying that the experiment could not be avoided, and the entire day that was wasted should have been rest time before the next mission.

Tomorrow morning, we will face new challenges.

Hashirama felt a rare bit of anxiety in his heart. They were helpless, like puppets controlled by the room, and seemed like they would slip into some abyss without realizing it.

And they can do nothing but obey.

The blood loss made Hashirama feel a little cold. If it were usual, he would certainly not mind hugging his brother to warm him up at this time - ah, Tobirama might mind a little, but in the end he would let him hug him obediently.

But now.

Hashirama sighed, wrapped the quilt tighter around him, forced himself to clear his mind, and quickly fall asleep to save up some energy.

Chapter 4

8.
The new experimental content and the new breakfast arrived as promised.

[Day 3:
A. Ask experimenter B to drive 5cm long steel nails into the backs of experimenter A's hands (Note: they must be removed after three hours);
B. Ask experimenter A to collect semen for experimenter B until the provided container is full.]

Hashirama stared at the TV and considered the possibility of completing Mission A before Tobirama woke up.

But that wouldn't work. The option stipulated that if the executor of the task nailed his own hand and got injured and the task wasn't completed, Tobirama might be so angry that he died.

The two steel nails were placed on the dining table. Hashirama measured them with his hands and felt that it was no big deal.

But obviously, Tobirama, who had just woken up, didn't think so.

"Choose B," he said, his voice a little languid, "Brother, you can tell which one is less harmful."

"Those are just two nails, Tobirama."

"But you don't have a Sage Body right now." Tobirama picked up a bun. The heated argument that Hashirama had imagined did not happen. He spoke rationally and said, "From a strategic point of view, that will be a wound that will affect your mobility in the next few days. As for me, I can recover almost completely after a good night's sleep."

Hashirama hesitantly sat down on the other side of the table.

"Let's finish this quickly," Tobirama didn't look at him, but seemed very relaxed, "so we can have more time to rest."

But when they actually sat down face to face, with the evil container next to them and Tobirama was supposed to take off his clothes, the atmosphere became very awkward.

When the atmosphere is relaxed, it is completely different from the situation last night when there was no time to think. I have to do more mental preparation and think about more things.

"This behavior is actually quite common, isn't it?"

Hashirama's eyes wandered, but he wanted to liven up the atmosphere: "I heard that many good friends, um, there are so-called sworn brothers... No, I mean..."

He gave up: "Either -"

But Tobirama's expression made him pause. His brother quickly stripped off the lower half of his body in the suddenly quiet room, then lay down with his hands neatly placed at his sides, as if ready to be punished.

Tobirama stared at the ceiling and said, "Brother, please start."

Hashirama hesitated for a moment. He felt his heartbeat quicken a little. It might be that the excitement of his sympathetic nerves had not yet passed, or maybe it was because the strong tea he drank for breakfast contained too much caffeine.

Tobirama was lying quietly, his upper body still covered with the Anbu combat uniform (which would become as clean as new at midnight every day), and his lower body completely naked, with his two long legs stretched out straight. Judging from the taut muscle lines, his whole body must be as hard as a coffin board.

"Uh-huh," Hashirama made a sound that was half a grunt and half a cough, "Then I'll begin."

Even though Tobirama was sure he was ready, when his brother's hand actually reached out to him, he still couldn't control himself and shrank slightly.

It's so hot.
How can a person who lost so much blood yesterday have such a high body temperature?

Tobirama was determined not to look at Hashirama's face. His gaze drifted away, but he could ignore what was within his field of vision. However, he could not ignore the touch coming from under him no matter what.

They are brothers who have a very good relationship. Of course, they always have physical contact in daily life. They even use the same bath products. Even the dogs at the entrance of the village sometimes smell them by mistake.

For the first time, Tobirama felt that there were so many differences between Hashirama and himself: just on one hand, the location of the calluses, the length of the fingers, the way the nails were trimmed, and even the touch of the skin.
When Hashirama held him tightly, a strong electric current ran straight up his spine from his lower abdomen. Tobirama pressed the tip of his tongue against his upper palate, trying hard to suppress a shameful moan.

Hashirama's breathing was also rapid, and sweat was almost oozing out of his forehead.

It's nothing, Hashirama kept comforting himself, it's just a mission, or just helping each other between men, it's normal, and it won't bring pain to Tobirama.

That thing began to rise amid his messy caress, and under the thin layer of warm skin, he could clearly feel the throbbing blue veins and even the flowing blood. Those things filled and expanded little by little, making Tobirama's limp penis gradually stand upright... How to say it, it seemed a bit magical.

The two brothers were deliberately avoiding looking at each other, but Hashirama could hear that Tobirama's breathing became heavy, and even stimulated a different rhythm with his movements. His pubic bone was stained a little red, and the muscles on the inside of his thighs became increasingly tight, like a bow stretched to the extreme.

A little clear liquid oozed out of the front end of the penis, slid down the shaft like tears, and was spread as Zhujian stroked it up and down, making his movements smoother. Zhujian's throat moved a little, and he rubbed the top hard with his thumb.

Tobirama suddenly gasped and almost jumped off the bed. The pleasure was like a whip that lashed his nerves directly. The intense pain broke down his solid defenses. His tense muscles relaxed uncontrollably and the soft flesh on his lower abdomen and thighs trembled.

"Uh..."

Hashirama's movements quickened. He was the kind of person who would concentrate on doing something once he had determined the direction.

The subtle and tense atmosphere of silence was broken, and the temperature in the whole room seemed to rise. Tobirama couldn't keep up with the rhythm, and his fingers couldn't help but clench the bed sheets tightly, but the pressure he could share was only a little bit. He arched his back at the intense stimulation that followed, and his teeth were sore from biting himself.

Tobirama ejaculated for the first time very quickly, and Hashirama grasped the timing very accurately. He quickly used a container to catch the gushing white liquid, without wasting a single drop.

"How is it?" Hashirama wiped the sweat off his brother who was breathing heavily with a towel, "Want to take a break?"

Tobirama shook his head and glanced at the container that was only filled to the bottom. His temple began to throb.

"Continue."

Well, Hashirama thought about the guiding principle he had mentioned earlier: quick victory and quick resolution.

It became much smoother after the first time, but due to inevitable physiological characteristics, each time it lasted longer. Fortunately, with Hashirama's physical strength, he didn't feel tired even though his chakra was sealed.

The awkwardness between them was also eased a lot, and sometimes they could even chat for a while - mainly to divert attention.

But when the container was finally more than half full, things started to look very different.

The continuous orgasms made Tobirama's body reach a very delicate state.
First, he became extremely sensitive, not only his genitals that were touched directly, but also his buttocks that were rubbed by the sheets and his chest covered by clothes. All the nerves in his body seemed to be exposed, and a series of sparks would be ignited at the mere touch, and those sparks accumulated in his empty brain, crackling.

But at the same time, he became very sluggish. His overused penis could hardly complete the task quickly. Even though the sour heat had accumulated to the point that his pubic bone was burning, that red thing was probably still half soft and could only spit out a little turbid liquid in vain and pitifully. When he was touched hard, Tobirama's whole body trembled.

His thinking started to become a little fuzzy.

"It's so hot..." Tobirama muttered absentmindedly, "Ah... slow down, don't touch there..."

He even shed tears, but they were meaningless tears. They were just the condensation of steam from the excessive pleasure, and the bright red wrinkles on his cheeks looked like they were about to drip blood.

Hashirama observed his brother's physical condition with concern and discussed with him: "Tobirama, take off your shirt too?"

It was difficult for Tobirama to express his objection at this time. His whole body felt sore, including his brain. Even Hashirama's voice seemed to be covered by a layer of vapor, floating and vague, and he could not hear it clearly.

But when Hashirama lifted the hem of his combat uniform, he heard a comfortable sigh, which encouraged him. He carefully unbuttoned his vest and rolled up the soaked fabric bit by bit, like carefully peeling a candy that was about to melt from a piece of candy wrapper.

The moment he was completely naked, Tobirama finally ejaculated again. His chest was pink, and his untouched nipples were swollen and red. This time the orgasm brought a more devastating blow to his brain. His entire waist was stretched into an exaggerated arc, his eyes almost turned white, tears flowed continuously, and even transparent saliva flowed from the corners of his slightly open lips, but he seemed unaware of it.

Hashirama looked at the container and it seemed that it would take about two or three more times.

But his brother looked in a state of disarray. The muscles on the inside of his thighs were twitching and he looked as if he had just been pulled out of the water. He no longer had the calm self-control he had in the morning, and untuned moans kept rolling out of his throat.

Hashirama had almost never seen Tobirama like this, and while he was disgusted by the evil physiological reaction that was inevitable in the process, he also felt distressed.

Tobirama paused for a long time, then blinked very slowly, and his mind, which had been floating like a spider silk hanging in the air, was finally brought back to the right line.

"Give me some water," he said, his voice also hoarse, "and then continue, brother."

"Don't you really need to rest a little longer?"

"No," Tobirama's tone began to show the impatience that Hashirama was familiar with, but his weakness made the severity less severe, "Are we on vacation? Please, brother, make it end quickly."

This arduous task had lasted from morning to afternoon, and despite constantly replenishing water and even stopping at noon to eat something, Tobirama was still about to collapse. His eyes went dark and when he was held by the waist and helped up, he was still trembling pitifully in his brother's arms.

It has come to this point, and we can only grit our teeth and persevere.

When Tobirama's penis stood up again, it looked exhausted. Hashirama tried to treat it gently, but the glans had become completely swollen from the continuous "torture". When it was touched, Tobirama could not tell whether it was pleasure or pain - or maybe both. He collapsed in his brother's arms in a daze, trying to concentrate, but with little success.

His skin all over his body seemed to be burning. Leaning on Hashirama was not much better than lying on the bed, perhaps even worse. However, he did not refuse this intimate position. Well, perhaps, more stimulation would be conducive to ejaculation.

When the penis was finally squeezed out of a little pitiful pre-cum, Tobirama couldn't help whimpering. He almost lost his self-consciousness, his nerves ached as if being pricked by needles, and he could no longer feel his lower body, as if his body below the waist had been soaked in hot water. As the water rippled and melted, tears couldn't stop overflowing from his eyes. Tobirama thought that the water that slipped out of his eyes might be more than the semen he successfully collected.

When the last bit of white liquid finally came out slowly from the tip, Tobirama's whole body twitched chaotically. Everything in front of his eyes went dark, and he didn't even realize that he had ejaculated. His tongue stuck out softly from his lips, which could not close, and his lower body thrust up and down uncontrollably, and after the initial little bit of semen, more clear liquid was ejected.

Hashirama stared blankly at his brother who was unconscious and incontinent. His scalp felt numb and a sour and hot flame burned unstoppably towards his lower abdomen. He shuddered at the warm and sticky touch of his lower body, and his mind went blank when he realized that he had actually ejaculated like that.

The container was almost full, but the TV made a sound indicating that the task was completed.

[Experimenter B is detected to be incontinent X1, triggering the hidden condition, completing the third day's task ahead of schedule, and rewarding 10 points.
Current points: 30. ]

While Hashirama was cleaning up the dazed Tobirama, he still hadn't come to terms with his evil behavior.

He simply couldn't believe it, nor could he understand how it was possible for him to feel any emotion other than heartache and anger towards Tobirama in that state?

Having an erection during the whole process is already enough to make people feel guilty, but that can also be attributed to the visual stimulation generated by the sexual act itself, but being excited to the point of ejaculation - that is abnormal no matter how you think about it.

Hashirama was in a mess. He was thankful that Tobirama was completely unconscious at the end and was not far from fainting. Otherwise, he would not be able to explain to his younger brother how his brother could be such a pervert.

The room provided complete bathing facilities. Hashirama quickly helped Tobirama clean up and took a quick shower himself. When he walked out of the bathroom carrying the already asleep Tobirama, he was surprised to find that the traces they had left not long ago had completely disappeared.

Although it was not yet midnight, the whole room seemed to have been thoroughly cleaned. Even their clothes were cleaned, folded into soft and fluffy squares and placed on the pillows. The smell brought by sexual intercourse was also swept away, and the bed looked extremely warm and comfortable.

Hashirama was silent for a moment, then tucked Tobirama comfortably into the quilt.

It was the right decision to start today's mission early in the morning. Tobirama could rest for about two hours before dinner, and then - Hashirama had to admit that, just as Tobirama considered, after a full night's sleep, Tobirama might be a little weak tomorrow morning, but at least still intact and healthy.

Hashirama also crawled into the quilt. Tobirama did not seem to be sleeping well. Although the mattress was soft enough, the afterglow of the climax still tortured his nerves, causing him to tremble from time to time.

Hashirama hesitated for a moment, then reached out and held the man in his arms, adjusting him to a more comfortable position.

This is for Tobirama.
He told himself, so that he could sleep well, that's all.
Nothing else.

Chapter 

9.
On the fourth day, they woke up at the same time, and the first thing they saw was a huge suitcase next to the bed.

That thing looked really ominous, especially when they saw today's mission on the TV screen.

[Day 4:
A. Ask experimenter B to cut off the thumbs of experimenter A (Note: Do not bandage within three hours)
B. Ask experimenter A to use the props provided in turn to perform prostate massage for experimenter B (Note: 1. During the whole process, experimenter B cannot ejaculate, and props are provided for blocking in this experiment; 2. Each time the props are replaced, the qualified judgment is prostate orgasm, that is, anal squirting; 3. Friendly reminder, if the props slip during the use of props, it will trigger punishment measures.)]

Tobirama opened the box.
Inside was a row of massagers that gradually grew in size and had increasingly hideous and bizarre shapes.

He swallowed hard.

"Don't think too much, brother." Tobirama slammed the lid shut before Hashirama could say anything. "No doubt, the requirements for the experiments will become more and more excessive, but option B will always only be about sex. In comparison, it is very safe."

Hashirama even felt a hint of annoyance, perhaps caused by a feeling of powerlessness: "Very safe?"
He remembered how Tobirama was almost completely out of control yesterday. It was obvious that today's mission would be more difficult.

"It's much safer than having your thumb cut off," Tobirama said, "What if it doesn't grow back after you get out?"

"I will recover my immortal body when I get out. We can take a gamble. There is no injury that the immortal body cannot heal."

Tobirama: "You've always had bad luck in gambling."

Hashirama: "..."

Hashirama was going crazy: "But I, do you want me to just watch you get tortured? This, this kind of humiliation..."

"Sometimes you don't have a choice," Tobirama said, "You didn't ask me the last time an Uchiha made that request, did you?"

This seemed to be the first time they had mentioned the incident directly since that day.

Hashirama was stunned and speechless for a moment.

Tobirama seemed to smile silently: "So of course, we have to make the 'best choice'. The reason was already stated yesterday."

They spent a while studying how to use those... vibrators, then took a shower. Tobirama pressed his forehead, trying not to imagine what he would look like, and quickly took off his clothes.

After yesterday, it seemed that his ability to bear it was a little higher.

This is not necessarily a good thing. Tobirama trembled slightly when his naked body touched the sheets, and he thought vaguely, what will I become after ten days?

He didn't want to think about it.

Hashirama stood straight, watching his brother half-lying down on the bed, while the picture on the TV changed, vividly and naturally showing what "prostate massage" is through minimalist style.

Hashirama's fingers bent and straightened. Sometimes Tobirama's tenacity would suddenly surprise him. His brother still had no expression at this time.

Tobirama said in a hard voice: "Then please start, brother."

He said something similar yesterday, like some kind of bad invitation, which it actually was.
But as the one being invited, Hashirama didn't feel that he had any more dignity. He was another experiment, and his brother had to go through all this just to protect him.

Obviously, Hashirama thought, I should be the one who has the greater responsibility to provide protection.

He had been silent subconsciously just now when Tobirama mentioned that day.

He always felt that he couldn't say it to Tobirama, "That's because I am always willing to protect you with my life."

It sounds too sensational.

Hashirama knelt down and opened the box. Now that he had made the decision, there was nothing more to say. Even though his heart was beating erratically, his hand was steady as he took out the vibrator.

The first one looked okay. Hashirama compared it and found it was only slightly thicker than his thumb.

He looked at Tobirama again, his mouth dry at what he was about to do.
How was he going to say to his own brother, "Open your legs"?

But Tobirama took the initiative to solve this problem. He didn't say a word, his eyes looking at the ceiling, his legs bent stiffly and opened to both sides, which exposed his entire lower body.

"Come on... Brother."

Well, Hashirama thought, quick and decisive.

Hashirama's fingers touched the small opening. Tobirama had just taken a shower and his skin was slightly damp. The entrance that had never been visited by anyone turned a little pink and shrank nervously when it touched his fingers.

Hashirama gritted his teeth and tentatively inserted a finger.

This was completely different from what happened yesterday. After all, masturbation was something many men knew how to do, but today... he had absolutely no experience at all.

The feeling was very wonderful.
Hashirama only had to insert a knuckle and could feel how the soft flesh of the hole was tightly wrapped around him, as if it was rejecting him, but also as if it was inviting him to move forward.

According to the "operating guide" on TV, he first had to find the point that would make Tobirama, ahem, happy.

Hashirama was tentatively moving forward without any plan, and he could feel Tobirama trying his best to relax and match his movements.

They seemed to be conducting an experiment to push the limit, and when Hashirama felt a little sluggishness, he instinctively twisted his fingers, which allowed him to push a little deeper.

Tobirama snorted faintly, but the sound was quickly suppressed behind his teeth.

The temperature was rising, and Hashirama felt himself sweating, with sweat flowing from his temples and sliding down his jaw to his neck. He knelt above Tobirama, one hand on his waist and the other buried in his butt. Tobirama had closed his eyes, and he seemed to be trembling slightly.

The eyes suddenly opened.

Hashirama was caught off guard; his brother's pupils were crimson, just like the lines on his face, and now those deep red pupils had enlarged, almost to five times their original size.

"Yeah..."

At the same time, Tobirama couldn't help but scream out, his waist bounced upward, his toes suddenly curled up, revealing an almost terrified look.

Because of the vibrator on the first day, Tobirama misjudged today's task. That kind of thing that can rub out bleeding and can only vibrate roughly is certainly different from a real prostate orgasm.

Hashirama paused for a moment, realizing that he had found it.

He poked at the slightly raised piece of soft flesh again, not daring to use too much force, but Tobirama couldn't control himself and shuddered again. His knees, which were spread out on both sides of his body, began to move inward unbearably. He tried to close his legs, but then struggled to open them under the control of his mind.

Hashirama swallowed again, and he felt that his saliva was now excessive compared to the excessive dryness at the beginning.

Hashirama memorized the position, pulled out his fingers, and replaced them with a transparent massager.

He hesitated for a moment, then pulled Tobirama's hands and asked him to hug his thighs.
"You can lend me some strength, and don't always hold it in. There's nothing to be ashamed of if you scream out."

Tobirama blinked several times, not knowing whether he heard it or not.

Holding the thin stick, Hashirama recalled the location he had just found and moved with a clear goal in mind.

"Ah...Ah...!"

Tobirama tilted his head back. Unlike the gentle fingers just now, the cool rubber product poked his sensitive spots again and again at a very fast speed. The pleasure turned into sourness that blocked his throat. He wanted to arch his body impatiently, but because of his current posture, it seemed as if he actively lifted his buttocks and welcomed it into Hashirama's hands.

"No... Haah, brother... Slow down..."

The unprecedented feeling made Tobirama like a frightened bird. He seemed to be firmly controlled by the giant hand called pleasure. He had no thought of resisting, but he could not bear the tide of sexual desire. He held his legs tightly with both hands, his fingertips dug into his buttocks, but he could not share the panic brought by the feeling of losing control.

The dry intestines even began to secrete lubricating fluid on their own. Hashira's movements became smoother, and the massager made a slight hissing sound as it went in and out, even squeezing out tiny bubbles.

The tip of Tobirama's penis also stood up, and he looked even more excited than yesterday. Hashirama then remembered the note requirements of Task B, that Tobirama was not allowed to ejaculate today.

There was a ribbon in the box, and Hashirama used it to tie a bow around his brother's genitals.

Tobirama's neck, which he had tried hard to raise, fell back onto the pillow and he let out a whimper.

She was so close to reaching the climax, but the orgasm that was pushed back was even more intense, and Tobirama's whole body trembled as if an electric shock had occurred. Her waist and hips were tense, and as Hashirama continued to thrust without any slackening, a white light flashed before her eyes that covered her head.

The deep part of the vagina suddenly tightened, and Tobirama couldn't help but let out a short scream, and more fluid gushed out. Hashirama pulled out the vibrator in surprise, and saw that his brother's vagina was no longer blocked and was spasming uncontrollably. The deep red vaginal flesh was twisted violently, and drops of sticky clear liquid were squeezed out and slid onto the raised buttocks, pulling out translucent threads of lust as it dripped.

At the same time, a warm current rushed to the lower abdomen.

After this unprecedented climax, Tobirama was completely stiff for two seconds, and then he collapsed in the room as if all the strength was drained away. He was sweating all over, his limbs were spread out, and he fell limply on the bed, breathing heavily, his eyes blurred by tears and dazed.

The TV made a "beep" sound, indicating that the first massager had passed the trial.

Based on yesterday's experience, this experiment became more and more difficult as time went on. Hashirama put the first vibrator aside and picked up the second one.

In terms of diameter alone, the second massager was not much thicker than the first one, but it was made up of seven or eight smooth round beads. Hashirama just rotated the first three and buried them into Tobirama's hole, and he heard a distorted gasp.

"So, so weird..."

Tobirama pressed the back of his head against the pillow, trying hard to adapt to the overly strange feeling in his anus. He seemed to be... being stuffed with eggs one by one. Every time he pushed past the thickest part of the bead, the bead that had already entered seemed to automatically slide deeper.

By the time Hashirama had stuffed all the beads in, Tobirama's tears had already flowed out. It was becoming increasingly difficult for him to maintain the posture of hugging his legs. His weak fingers slipped around the tight and raised buttocks, partly because of sweat and partly because of the semen flowing all over the buttocks.

Hashirama held his hand and wrapped his fingertips, which had turned white from exertion, in his palm.

He asked Tobirama to change his position and lie on his side with his back facing him. He then leaned closely behind Tobirama, raised one leg, and let his brother's weak thigh rest on his leg.

The movement was like some kind of fixed posture in a fight, Tobirama was fixed in place without any resistance, his thighs were spread wider, and he couldn't even close them a little.

This action made it easier for the massager to reach the sensitive point at the front end. Tobirama's cheekbones were flushed, and he now seemed to be curled up in his brother's arms. He could even hear his rapid heartbeat behind his thick chest.

When this massager started to thrust in and out, the stimulation it brought was even greater than before.

One bead after another rolled over the sensitive points, each time bringing direct and vivid stimulation. The rhythm was like a storm, so dense and frightening. Tobirama shivered and raised his head, his legs tensed to the point of pain.

He... wanted to ejaculate so much. The simplest and most direct way to obtain pleasure was firmly blocked. The feeling of the waves surging up and being forced to suppress made him dizzy. Even the tip of his tongue unconsciously stuck out of his lips, and his eyes went dark.

Tobirama soon reached another prostate orgasm. He hung on the cross made of his brother's body, his whole body shaking like a leaf in the wind. The feeling of streams of water flowing out of his buttocks was extremely shameful, almost like some kind of weird incontinence.

The third massager suddenly became thicker.

Hashirama felt hesitant when he took them out. Although he didn't know why, he compared them with the erect penis in his memory and found that none of the six tools in the box were as majestic as his.

But - no matter what, the door is so small and so tight, how can such a thing be stuffed in it?

"Bear with it, Tobirama," Hashirama said cautiously as he prepared to insert, "This might hurt a little."

Pain is nothing, his distracted brother thought drowsily, a little more familiar pain might help to keep him awake.

After two orgasms, Tobirama's anus was already wet and sticky. The opened hole swallowed the head without much effort, but it encountered some resistance during the subsequent entry.

From the perspective of the pillar, he could clearly see how the thick and long rod wetted by the love juices slowly and erotically stretched out the intestines that were constantly swallowing and spitting out, like pushing apart the soft clam meat. The still immature little hole was stretched to a little white, but it still swallowed it instinctively and greedily. The liquid that had previously remained in it was glowing with love juices and was constantly being squeezed out from the gap.

"Ah..." Tobirama tightly grasped the bed sheet. The entry of something too big made him want to vomit, "I, can't...ah..."

When the massager entered and rubbed the sensitive spot, Tobirama was vaguely convinced that if his front end had not been blocked, he would have ejaculated directly because of this.

It was simply a punishment brought about by some kind of pleasure. The piece of soft flesh that had only been touched and teased before was now pressed tightly, without even a chance to breathe. The continuous pleasure hit his nerves like an electric current, and the muscles near his pubic bone spasmed exaggeratedly, like an arm that had lost strength after an intense battle.

A large amount of sticky liquid was secreted in a rush to protect the fragile intestines, but it did not help the pleasure that had been pushing to the top. In fact, because of the perfect lubrication, the waves of stimulation were even more vivid.

Hashirama looked worriedly at Tobirama, who seemed to be about to faint. He wanted to pause for a while, but when the vibrator remained motionless in Tobirama's butt, it didn't take long before Tobirama whimpered as if he was being intentionally tortured.

"Move, move it——" His voice became a little sharp, "Please, brother...haah...move it——"

Hashirama's heart nearly jumped out of his throat because of the crying and pleading. His lower body, which he had deliberately ignored, swelled again, veins throbbing, and the heat that urgently needed to be relieved made his already congested brain even hotter.

How could it be... why do I feel such a strong desire for someone like Tobirama?

Hashirama was almost overwhelmed by guilt, which made him fail to notice for a while how he instinctively thrust the vibrator into a fierce rhythm, as it was finally able to move smoothly with plenty of lubrication.

Tobirama couldn't even scream. He opened his mouth weakly, tears pouring out as if out of control, even the front end of his tightly bound body was spitting out streams of clear liquid, completely soaking the silk bindings. The rod in his ass seemed to want to penetrate deep into his intestines, breaking through all obstacles without a doubt, expanding his territory and wreaking havoc.

What called Hashirama back to his senses was the subtle tingling pain on his forearm. Tobirama seemed to have lost his mind and was biting his arm. Fluid from his anus was gushing out as if he was incontinent. The deep red intestinal flesh was screwed out of control, and foam accumulated at the opening of his anus from the intense thrusting and friction. He seemed to be suffocating, and his whole body was shaking as he hung on himself, and it seemed that he had lost consciousness.

Hashirama shuddered and subconsciously loosened his hand to touch his brother's face.

"Tobirama? Tobirama, are you okay?"

The pair of red eyes turned slowly, and Hashirama heaved a sigh of relief. Just as he was about to speak, they both noticed at the same time that instead of the "beep" sound indicating that a level had been passed, the TV set was covered with a layer of red light.

Having seen this scene, Tobirama's eyes suddenly widened.

The bright red "Warning!" appeared again.

[Detected violation X1, experimental prop 3 accidentally fell out during the experiment. Since experimenter A is the operator, punishment is implemented: forced blood collection of 350ml.
Execute immediately.]

The effect was immediate, and Hashirama spat out a large mouthful of blood before he could utter a single word.
The bright red, burning blood fell on Tobirama's shoulder, and he shuddered, trying to hold on to his weak hands and feet to look for the massager that had just fallen out.

"Hurry, hurry and put it back." Tobirama found the thing, but his hands were shaking so much and he couldn't see behind him, so he couldn't aim it right no matter what he did. Until Hashirama's hand held his again and pushed the thick massager back into his anus.

There was a "beep" sound indicating that the level had been passed, and Hashirama finally stopped vomiting blood.

10.The
fourth one looks very similar to the third one.

They rested for a while before that, replenished their food and water, and took a shower.

As the one who lost blood, Hashirama had a cup of red date juice, but he actually didn't feel anything. It was Tobirama, who still looked groggy, who needed replenishment more.

When Tobirama lay on the bed again, he no longer had the energy to feel ashamed of his nakedness. His expression could be described as one of being ready to die.

To prevent any accidents, he firmly rejected his brother's suggestion to help him untie the front end, even during the pause of the experiment. Who knows if that would cause "violations" again.

He was tired of letting Hashirama get hurt over such ridiculous things.

It was not too difficult for the fourth vibrator to enter. After all, after the first three vibrators had been used for a whole morning, Tobirama seemed to have mastered some strange technique.

In addition, he was always on guard to prevent the vibrator from falling out during the experiment.

Tobirama knelt on the bed, and Hashirama put a few pillows under his abdomen. This posture was relatively strenuous, so that he would not feel so painful during the spasms of orgasm.

After completely swallowing the vibrator, both of them breathed a sigh of relief. Hashirama asked Tobirama to switch, and when he was about to hold the bottom and pump it like before, the thing suddenly moved on its own.

"Haha..."

Tobirama let out a muffled groan due to the sudden and violent vibration, and his head almost exploded in an instant.

The fine and intense vibrations were simply incomparable to Hashirama's previous thrusts, even the last part that almost drove him crazy, the intensity was far from comparable to this moment, the vibrator was like crazy in his intestines, the pleasure was simply exploding, Tobirama's legs suddenly clamped together, his buttocks spasmed nervously, and his body went limp as if the force was released.

"No...no! Stop...ah, please...!"

Tobirama screamed incoherently, he could no longer bear it, his hands reached back randomly, trying to relieve a little the pleasure that was driving him crazy, but the rod was shaking so hard that he couldn't hold it at all. The waves of lust piled up layer by layer to an overload, almost drowning him. Tobirama stretched his neck back weakly, and soon he didn't even have the strength to hold on, and was finally forced to let out a sweet and wanton moan.

Hashirama wanted to help him, but just as he grasped the end of the vibrator, he was blocked by Tobirama.

"No...Ahhh...No, Brother, I can't drop it...Ugh—!"

The little hole that had been trained to perfection began to flow with water skillfully. Tobirama's cheeks turned red, his eyes rolled back, and even the tip of his tongue was about to stick out. He was devastated and didn't know how to beg for mercy, but he instinctively blocked his brother's hand, pushing the torture instrument that was torturing him randomly, trying his best to protect it from falling out.

Hashirama was so upset that he was furious, but what made him even more furious was that he was hard again.

When he took a shower at noon, he secretly released himself in the bathroom. At that time, he had just finished cleaning Tobirama, and his exhausted brother fell into a short sleep just across the wall. He took advantage of the sound of water to do such a sinful thing. While doing it, the scenes in the morning kept appearing in his mind.

Hashirama felt that he was simply broken, but at this point, he seemed to have to admit that he had desires for Tobirama.

It's not the kind of thing that happens naturally when seeing an eye-stimulating scene. The first Hokage has always been proud of his self-control and is definitely not a loser who indulges in obscene desires.

But the lust he felt now was only for his last remaining brother, who was his closest blood relative, and because it was Tobirama, the lust became so unbearable.

Hashirama gritted his teeth and actually hoped to be punished by the system again - if he wasn't afraid of making Tobirama worry, perhaps the pain and blood loss would make him more sober.

Hashirama didn't need to control this vibrator, so all he could do was try to make Tobirama more comfortable.

The massager was shaking crazily, and at the same time, Tobirama could feel that the shaft was no longer smooth as before, but instead had rough particles, and even a small electric current appeared later, continuously ravaging his almost collapsed flesh. The intestinal wall was forced to swallow and stimulated to spasm, and more love fluid was continuously secreted, which was rubbed into foam at the hole that was stretched to the limit, and dripped out because of too much, leaving crystal traces along the twitching thigh muscles.

Tobirama's voice was already hoarse, and sweat and tears had completely blurred his vision, leaving him unable to do anything but collapse in a daze and squirm in Hashirama's arms.

He was shaking with pleasure all over and couldn't even utter complete sentences, his head was a mess and he was tortured to despair by the impending but blocked climax, his strong and lean body was a lustful peach pink and even his skin looked thinner, as if a gentle pinch would squeeze out abundant juice.

During the final climax, Tobirama's whole body was convulsing, and Hashirama let his chin rest on his shoulder to prevent him from suffocating from the lack of oxygen in the passion.

Tobirama's body was so hot, so soft, and wet everywhere. This was his almost completely unfamiliar brother, Hashirama couldn't help but think. No matter how much he despised himself, he couldn't help but think about it.

This kind of Tobirama is also likable.
Or rather, no matter what kind of Tobirama it is, he likes it.

The experiment was forced to be suspended for half an hour again at Hashirama's insistence. They only had the last level left to complete in today's mission, but it was conceivable that the last level would also be the most torturous.

And that last vibrator... Hashirama stared at it in silence, wanting to break it in pieces.

It was a thick, long rod, densely covered with smooth, short white hairs, cool and slippery to the touch, and it was not difficult to imagine what kind of torture it would cause when they were full of juice and mixed into a mess in the tender intestines.

Tobirama soon learned the lesson.

In fact, he was finding it difficult to think in paragraphs now. Like the previous one, this vibrator moved on its own, but it did not have those agonizing, fine vibrations. Instead, it twisted and thrust wildly, fucking the soft intestines like a real, deformed cock.

The back of the door was filled so full that there was not a single space left. The tender red intestines were forced to be stretched open and violently pumped in and out. The intestinal flesh was even brought out a little, and then it was all pushed back in. The red buttocks trembled as they were pulled out, and streams of intestinal fluid came out uncontrollably, and were pumped so hard that the juice splashed everywhere.

The penis in front of Tobirama, whose outlet was blocked, had turned red and purple, and he looked like he was about to faint.

Hashirama held his brother in his arms and kept helping him to breathe, but it had little effect. Tobirama almost lost consciousness. Every time he was penetrated to the deepest point, he had the illusion that he was being penetrated into his intestines. His back was manipulated so hard and pleasurably that it even began to burn. He was about to lose consciousness. His prostate was pressed and rolled mercilessly, and there were those soft hairs...that was the worst thing. The wet short hairs brushed against the allergic and spasmodic intestinal walls inch by inch, as if a bug was crawling over, bringing a sharp itch, which added fuel to the unrelieved desire.

"Help me..." Tobirama cried in a daze, hugging his brother's shoulders tightly, as if he was holding on to a life-saving straw, "No more... Ahhhh...!"

Finally, when it was about to reach the climax, Tobirama could no longer move. At this moment, the thick silicone rod suddenly shook, and then a stream of warm water suddenly spurted out, hitting his sensitive points that had already been overwhelmed!

Large streams of water flowed endlessly and seemingly without pause. Tobirama's whole body was tense, like a suffering sacrifice. He could not even feel that he had reached orgasm, but only shed tears and drooled. His lower body was forced to spasm and move, but the front end was so tightly bound that he could not ejaculate anything.

When Hashirama heard the last "drop", he immediately hurriedly helped his brother untie the front. In his arms, Tobirama was like an out-of-control sex toy, the purple-red front was motionless at first. He stroked it twice as gently as possible, and suddenly a desperate scream rang in his ears.

After a long period of confinement, the sexual organ that was tortured to the brink of limit finally ejaculated, and a large amount of white turbid liquid mixed with indescribable liquid sprayed all over the bed. Hashirama quickly pulled out the vibrator that was still wreaking havoc, and the overloaded anus also flowed out of water.

Tobirama was nailed in this continuous and terrible climax and fainted completely in the mess.

Chapter 6

11.
Tobirama didn't even have the energy to wake up for dinner.

He was completely unconscious, as if he had just been through an extremely difficult battle - in terms of the extent of physical injuries, this could not be compared with any truly "difficult" battle, but judging from the exhaustion suffered by the two brothers, they had not been so miserable for a long time.

Hashirama touched his brother's forehead and was relieved to find that he at least didn't have a fever.

"Tobirama," Hashirama coaxed softly, "Get up and eat something. Be good."

The person on the bed just wrapped himself tighter in the quilt, closed his eyes tightly, and decided to turn a blind eye to the temptation.

Hashirama felt like laughing.

Even when Tobirama was very young, there seemed to be very few scenes like this between them: the elder brother coaxing the willful younger brother to eat or take medicine.

Tobirama is a pragmatist. Even when he was a cub, he would never mistreat his body because of his willfulness. Sometimes, Hashirama would rather he was a little willful.

Hashirama poked his brother's face.
"You need to replenish your energy, Tobirama. Do you want to starve until tomorrow morning?"

The man muttered something that sounded like "Stop bothering me."

Hashirama simply pulled him up, and Tobirama leaned limply in his arms. In that position, Hashirama put the soup spoon under his nose.

It felt so strange.
It seemed like just another way of getting along, the natural role of elder brother, but it seemed like there was something else.
Their relationship had undoubtedly changed, and Hashirama was surprisingly more sensitive to this change. He watched Tobirama frown helplessly and open his mouth to eat the food in his hand, watching every inch of his expression, lips, and collarbone exposed under the slightly loosened quilt, and his Adam's apple moved slightly.

He had desires for his brother.
Compared to the shock he felt when he first discovered this, Hashirama now accepted this calmly.

They are always together, always with a bond and affection that cannot be severed by anything. What does it matter what this affection ultimately ends up being?

In comparison, the need to get out of here is more urgent.

Dinner took longer than usual. Tobirama remained indifferent the entire time, but he obediently ate every bite of food that Hashirama fed him. He almost seemed a little squeamish.

After making sure that he had barely replenished the required energy, Hashirama finally let his brother go. After that, Tobirama finally got peace and fell into a deep sleep, unaware that his brother was still holding him in his arms, looking at his face in the dark.

On the morning of the fifth day, when the two woke up, they finally did not see any new "props" that challenged their cognition anywhere in sight. Tobirama quickly scanned the room and secretly breathed a sigh of relief.

There is only a small box on the table, which doesn't look very lethal.

But the TV screen flickered, which quickly shattered their hope.

[Day 5
A. Ask experimenter B to pull out all of experimenter A's nails (Note: they must be completely separated, without any adhesion residue)
B. Ask experimenter A to perform penetrative sex on experimenter B (Note: 1. The completion standard of the experiment is that both people ejaculate at the same time.)]

Compared with the previous few days, today's experimental arrangement was very simple. There were no embarrassing annotations and detailed explanations, and there did not seem to be any new tricks that were too embarrassing.

but......

Tobirama stared at the simple two lines of words, completely frozen.

If he could still deceive himself in the past few days and treat those shameful actions as just tasks, but today, today, he would no longer use props, but his brother would personally...

Hashirama stood aside, looking relatively relaxed.

Compared to the torture that the experimental tasks in the past two days brought to Tobirama, today's task B seems to be much friendlier.

"Tobirama?"

Tobirama turned back reflexively: "Let's choose B."

"Well," Hashirama didn't want to argue with him about this, he just confirmed his expression and nodded, "Okay."

Tobirama avoided his gaze.

He suppressed his nervousness - he still couldn't get used to it, especially today's mission, which was completely different from the previous ones.
...It was a real, most intimate contact.

For a moment, Tobirama didn't dare to look at Hashirama's face. He was not sure whether his brother would feel disgusted by this matter. After all, he was a man and they were brothers.

But he himself...
Even though his desire to sacrifice himself to protect Hashirama was genuine, at the same time, Tobirama could not say that he had a strong resistance to the whole thing.
Perhaps, the feelings he had for his brother were never too simple.

But in this room, after being forced to do these excessive things, Tobirama didn't dare to think about what kind of person he would become in his brother's heart.

Tobirama took a deep breath, walked to the bed, and whispered to himself: "...I can do it."

He didn't look back, but just took off his clothes:
"Please, brother."

12.
Things were extremely awkward from the very beginning.

When Tobirama was lying on the bed and Hashirama was on top of him, with only their upper bodies naked, the air in the room almost stagnated. Tobirama's eyes dodged and finally fixed on the ceiling, determined to avoid any eye contact.

But this time, Hashirama didn't let him dodge.

Hashirama cupped his brother's face, forcing him to meet his gaze.

Tobirama: "..."

What was going on... He was forced to look up, and was captured by his brother's sincere and frank gaze. Hashirama looked at him so seriously, just like, just like looking at, a lover or something...

Tobirama hissed softly without sounding anything, and felt his face getting hot under such an untraceable gaze.

"Brother, brother..."

"Don't be afraid, Tobirama," Hashirama said with a smile in his eyes. He leaned down slightly and kissed his forehead first. "Does this feel annoying?"

"..." Tobirama's eyes drifted away, and he quickly replied, "Of course not."

But Hashirama, why would he ask such a question?
He acted as if they were not forced into disgusting intercourse, but were in love and it was a natural thing.

Hashirama lowered his voice: "What about this?"

He naturally moved down and gently bit his brother's lips in a light kiss.

But that was enough to stun Tobirama. Even if he was slow, it was not difficult for him to discern the lingering emotions in this kiss.
Hashirama was never someone who would force himself to act... He really didn't seem to hate this kind of thing.

But Tobirama soon didn't have the energy to think more, and Hashirama deepened the kiss.

He kept his eyes open, looking intently at his brother beneath him, and many images appeared in his mind uncontrollably.

In the previous few days, Hashirama had seen these lips open in a daze, and seen the lips wet with saliva and tears. They had also kissed on the first day, and Tobirama even... wrapped him here, licked, sucked, and finally swallowed his semen.

But that was very different. Their first kiss was like a battle, full of fear and blood. Now think about it, these days at least one of them was tortured to the point of being almost insane, and they hadn't even looked into each other's eyes properly.

Tobirama let out a very slight groan.

The two closest brothers were pressing their skin against each other. In fact, after a long period of joint training and fighting, they were already very familiar with each other's bodies, but the touch at this moment was terribly strange. Arms touched arms, chests rubbed against chests. Tobirama trembled slightly, and he wanted to avoid his brother's kiss, but was gently held on the back of his neck.

"Relax a little, Tobirama," the other party's tone even seemed to be instructing him on martial arts, "Relax a little, or you will get hurt."

But then, how can I...

Tobirama felt very hot, it was all because of Hashirama's high body temperature. They were so close, and Hashirama was licking and biting his lips, making soft kissing sounds. The hot air from his breath was trapped in the small space. Tobirama felt that soft and slippery tongue, his body was stiff like a board, and he felt dizzy.

I don't know when I relaxed my clenched teeth.

Hashirama had expertly pushed this kiss to the point of passionate intimacy. He obviously wasn't supposed to have any experience, but he was able to control Tobirama's body very comfortably, invading his mouth, stirring his tongue that had nowhere to hide, and accepting his brother's sensitive tremors as the contact became deeper and deeper.

"Um... Stop kissing me..."

Tobirama felt very dizzy and he couldn't breathe. Hashirama was like a soft and hot net that tightly covered him. His ears were numb from the entanglement of the net, his fingers curled up and clenched, and then separated at a loss. He never dared to meet his brother's gaze, but finally felt as if there was nowhere to escape.

Thirst burned his blurry mind and his whole body seemed to be burning. Tobirama almost wanted to curl up in the airtight kiss, but in the end he could only rub Hashirama's neck involuntarily.

For a moment he forgot what they were doing, but soon today's clear mission popped into his mind.

"Brother," Tobirama struggled to find an opportunity between kisses, his face was already red, and his breathing was completely disordered, "Don't... don't do these useless things, we have to, we have to complete the task quickly-"

Hashirama glanced at him, his smiling expression didn't seem to change: "Okay."

The elder brother was extremely quick and immediately removed the last bit of cloth from their lower bodies.

His skin involuntarily shuddered slightly when it came into contact with the cool air, and Tobirama was stunned and couldn't help but shrink back.

His eyes, which had been avoiding the view, involuntarily turned downwards, noticing the penis that was exposed after his brother took off his pants. It was really, really...

For a moment, Senju Tobirama was a little doubtful. In addition to the psychological pressure, today's mission would also be more physically difficult than the previous two days.

Hashirama's hand also began to move downwards.

Tobirama's scalp numbed, and he became somewhat aware of his words, which seemed to be an invitation. But Hashirama's warm hand reached the base of his thighs, inserted between his tightly closed legs, and his fingers touched his anus, which had begun to react.

It was actually slightly wet there. Hashirama raised his eyebrows barely noticeably and pretended not to notice.

If I tell you now, Tobirama will be furious, but unfortunately, during the four consecutive days of missions, his body seems to have been subtly transformed.
——It can't be said to be in a bad direction.

Hashirama pressed the corners of his lips, used two fingers to separate the taut buttocks, and tentatively circled his fingertips around the small opening.

Tobirama took a deep breath, closed his eyes as if to cut off his arm, and followed his force to spread his legs a little.

Hashirama inserted a knuckle.

hiss......

With yesterday's experience, he pushed through the warm soft flesh with ease and came to the place that could make his brother lose control. Thanks to the delicate kissing and caressing just now, there was obviously no resistance here like yesterday, and even some natural liquid lubrication seeped out, making his entry smoother.

Tobirama bit his lips hard and closed his eyes, as if this could deny the fact that his brother was playing with his butt.

But the irresistible pleasure still came honestly. The kiss just now seemed to make his body more sensitive. Tobirama could hardly hold back the moan in his throat. Hashirama's fingers pressed on that piece of soft flesh slowly, which made his whole lower body go limp and his legs lost their tension.

He kind of wanted to beg his brother to stop dawdling, to insert it quickly, and then to quickly complete the damn task of ejaculating together, but he couldn't help but think of the size he had just seen... and he had to admit that perhaps his body needed more preparation.

The injury wasn't that terrible, but even Tobirama didn't think he could ejaculate smoothly in that much pain.

The untouched front end of Tobirama's penis slowly rose up, and while Hashirama was exploring his anus, he was stroking his penis while thinking - the key to this mission was "timing", how could two people reach orgasm at the same time?

The number of fingers gradually increased to two, then more. When the number of fingers increased to four, Tobirama's face was already flushed, and he raised his hips slightly uncontrollably to make the difficult swallowing of the anus less painful. He tightly grasped the bed sheet, and the veins of endurance appeared on the side of his neck pressed against the pillow. Finally, he couldn't help but urge:

"It's ok...Brother, please, please come in."

Hashirama paused, he had almost reached his limit of endurance, and after fully understanding his feelings for Tobirama, his resistance to his brother who was soaked in sexual desire seemed to become even weaker.

Hashirama withdrew his hand, which was already dripping with juice, stared intently into Tobirama's eyes, and moved closer with his waist raised.

When the thick head entered, both of them paused in breathing.

Hashirama couldn't help but raise his head. It was really... really, so comfortable.

He had never imagined this scene before. Even though he realized that his feelings for his brother had deteriorated, and even though he had relieved his desire for Tobirama's body, when he actually inserted it into that warm and soft hole, the stimulation of being wrapped so delicately still gave him a shock. The pleasure jumped from his lower abdomen to the top of his head, and fireworks exploded in his brain.

Hashirama grabbed Tobirama's thin waist and thrust hard into him almost instinctively!

"Ah...!"

Tobirama screamed in surprise. Despite a gentle foreplay, the size of the thing that exceeded his tolerance still made him feel like he was almost torn apart. White light exploded in front of his eyes. The thick pillar of meat rushed in like a siege, breaking through layers of intestinal flesh and crushing heavily on the already slightly swollen sensitive spot, bringing extremely strong and continuous stimulation.

The stimulation was simply too much, especially for Tobirama.

In the experiments of the previous few days, he had been forced to endure quite high intensity sexual pleasure, but that was completely different from now.

Those dead objects, or just Hashirama's hand, were completely different from his brother truly entering his body and them truly becoming one...

And at this moment, after a long period of accumulation in the early stages, that kind of hidden desire and rebellious feelings, through the most intimate physical contact as a carrier, suddenly and unimaginably broke out.

Tobirama's waist suddenly spasmed, and he was completely out of control. The moment Hashirama completely penetrated him, he screamed "Brother" and was forced to ejaculate by the intense pressure and satisfaction!

Tobirama couldn't control himself, and neither could Hashirama. His anus tightened the moment his brother reached orgasm, and it made his scalp numb. At first he tried to move as gently as possible, but his lower body moved uncontrollably, and he thrust hard again and again amid Tobirama's helpless moans.

"Ah... Brother, don't, slow down a little bit—ah!"

Tobirama's waist was completely arched, and he wanted to close his legs that were spread out to the sides, but he was blocked by Hashirama who was lying on top of him. His extremely sensitive intestines, which were in climax, kept feeling deep stimulation. He could only clamp Hashirama's waist tightly, but he was constantly shaken by his thrusting movements, and his whole body was like a small boat floating in the raging sea of ​​desire.

But Hashirama simply couldn't slow down. He was swept up by the incomparable pleasure of desire, and he rammed forward again and again in a daze. The more he thrust his swollen cock, the more it was wrapped tightly by the spasming intestinal flesh, and more clear fluid was forced to seep out, making his movements smoother and the pleasure surged up in waves, urging him to thrust more fiercely.

Hashirama thrusted for several hundred times, and finally his eyes went blank and he ejaculated.

A large amount of hot semen was mercilessly shot into the deep of the intestines. Tobirama's voice was almost hoarse. He trembled in Hashirama's arms, trembling with the rush of liquid. His eyes rolled back and he almost ejaculated again.

"no......"

Tobirama still had a trace of rationality left, even though tears were thrown out of his eyes as he shook his head weakly: "Brother, help me... We have to do it at the same time-"

Hashirama was breathing heavily, he hugged Tobirama's body tightly, his lower body still moving slowly and gently, enjoying the afterglow of the intense climax. He squeezed one hand between their two tightly pressed bodies, found Tobirama's penis, which was beginning to flow with excitement again, and blocked the rapidly opening little mouth.

Tobirama's waist trembled violently, and he was speechless for a moment, his collarbone was stained red.

It was not pleasant to be forced to come down from the climax, and Tobirama's nose was physiologically sore. Hashirama began to kiss him again, sweeping the liquid on his face that was either saliva or tears into his mouth, then captured his lips, exchanging each other's breath and body fluids.

Hashirama quickly regained his spirits and they began their second attempt.

After ejaculating once, Hashirama's rationality had obviously returned a lot. He observed Tobirama's condition and thrust slowly and deeply. His scorching gaze and uninterrupted penetration brought him an incomparable and lasting pleasure, which was completely different from the direct and intense stimulation. It was more prolonged because it was slowed down, like a wave that was always suppressed below the peak, surging wave after wave, never stopping.

Tobirama soon couldn't bear it anymore. He was almost collapsed by his brother's abnormally burning gaze today, not to mention the most direct physical stimulation - at this moment, although Hashirama was kind enough not to attack that piece of soft flesh accurately, it was too thick. Every time he pushed deep into it, he couldn't avoid crushing that place hard. Tobirama began to feel the maddening sourness of yesterday again. The blocked front end aggravated the sensitivity of his back hole. He had wanted to ejaculate again, but this time Hashirama was terribly durable. He repeated the thrusting action tirelessly, as if he was determined to squeeze more juice out of the body under him.

Tobirama was indeed leaking water constantly, like a sponge, with water being squeezed out of all parts of his body. Tears made the corners of his eyes red and swollen, and the blocked front end was also slowly leaking clear liquid, especially from the ravaged anus. The obscene sound of water was extremely loud in the empty room. He shivered unconsciously to cater to Hashirama's invasion and kiss, and kept muttering "brother" unconsciously. He didn't even know what he was saying. He just tried hard to avoid Hashirama's gaze that seemed to be cutting him open. He couldn't help but hugged Hashirama's neck and buried his face in his neck like an ostrich.

When Hashirama licked and kissed Tobirama's earlobe, Tobirama cried out. The sticky sound of water was amplified in his ears, and together with the sound of water in his lower body, it was like a sea of ​​desire that completely overwhelmed his reason. Tobirama almost forgot who he was and where they were. He just cried uncontrollably, his waist moving helplessly, as if he was actively responding to his brother's fucking in a lewd manner. The obscene fluid flowing out of his anus was squeezed into a circle of foam, which then dripped onto the bed sheets, covering his round buttocks with sticky liquid.

When Hashirama finally ejaculated again, Tobirama had almost completely lost consciousness. He didn't know when his brother let go of his penis, which had been suppressed to the point of numbness, nor did he know how many positions they had changed. He just spasmed unconsciously when he was burned by the semen rushing deep into his intestines, and his swollen and painful lower body also spit out streams of white semen. They hugged each other tightly, almost merging the two into one, until the "beep" sound representing the completion of the mission was rang out, and neither of them made any other movements.

They maintained such a close posture, Hashirama tightly hugged his most precious brother for a long, long time, and the blurred consciousness Tobirama also instinctively rubbed against his arms.
They are the closest relatives in the world, connected by blood.

Chapter 7

11.
Tobirama didn't even have the energy to wake up for dinner.

He was completely unconscious, as if he had just been through an extremely difficult battle - in terms of the extent of physical injuries, this could not be compared with any truly "difficult" battle, but judging from the exhaustion suffered by the two brothers, they had not been so miserable for a long time.

Hashirama touched his brother's forehead and was relieved to find that he at least didn't have a fever.

"Tobirama," Hashirama coaxed softly, "Get up and eat something. Be good."

The person on the bed just wrapped himself tighter in the quilt, closed his eyes tightly, and decided to turn a blind eye to the temptation.

Hashirama felt like laughing.

Even when Tobirama was very young, there seemed to be very few scenes like this between them: the elder brother coaxing the willful younger brother to eat or take medicine.

Tobirama is a pragmatist. Even when he was a cub, he would never mistreat his body because of his willfulness. Sometimes, Hashirama would rather he was a little willful.

Hashirama poked his brother's face.
"You need to replenish your energy, Tobirama. Do you want to starve until tomorrow morning?"

The man muttered something that sounded like "Stop bothering me."

Hashirama simply pulled him up, and Tobirama leaned limply in his arms. In that position, Hashirama put the soup spoon under his nose.

Compared to the shock he felt when he first discovered this, Hashirama now accepted this calmly.

They are always together, always with a bond and affection that cannot be severed by anything. What does it matter what this affection ultimately ends up being?

In comparison, the need to get out of here is more urgent.

Dinner took longer than usual. Tobirama remained indifferent the entire time, but he obediently ate every bite of food that Hashirama fed him. He almost seemed a little squeamish.

After making sure that he had barely replenished the required energy, Hashirama finally let his brother go. After that, Tobirama finally got peace and fell into a deep sleep, unaware that his brother was still holding him in his arms, looking at his face in the dark.

Compared with the previous few days, today's experimental arrangement was very simple. There were no embarrassing annotations and detailed explanations, and there did not seem to be any new tricks that were too embarrassing.

but......

Tobirama stared at the simple two lines of words, completely frozen.

If he could still deceive himself in the past few days and treat those shameful actions as just tasks, but today, today, he would no longer use props, but his brother would personally...

Hashirama stood aside, looking relatively relaxed.

Compared to the torture that the experimental tasks in the past two days brought to Tobirama, today's task B seems to be much friendlier.

"Tobirama?"

Tobirama turned back reflexively: "Let's choose B."

"Well," Hashirama didn't want to argue with him about this, he just confirmed his expression and nodded, "Okay."

Tobirama avoided his gaze.

He suppressed his nervousness - he still couldn't get used to it, especially today's mission, which was completely different from the previous ones.
...It was a real, most intimate contact.

For a moment, Tobirama didn't dare to look at Hashirama's face. He was not sure whether his brother would feel disgusted by this matter. After all, he was a man and they were brothers.

But he himself...
Even though his desire to sacrifice himself to protect Hashirama was genuine, at the same time, Tobirama could not say that he had a strong resistance to the whole thing.
Perhaps, the feelings he had for his brother were never too simple.

But in this room, after being forced to do these excessive things, Tobirama didn't dare to think about what kind of person he would become in his brother's heart.

Tobirama took a deep breath, walked to the bed, and whispered to himself: "...I can do it."

He didn't look back, but just took off his clothes:
"Please, brother."

12.
Things were extremely awkward from the very beginning.

When Tobirama was lying on the bed and Hashirama was on top of him, with only their upper bodies naked, the air in the room almost stagnated. Tobirama's eyes dodged and finally fixed on the ceiling, determined to avoid any eye contact.

What was going on... He was forced to look up, and was captured by his brother's sincere and frank gaze. Hashirama looked at him so seriously, just like, just like looking at, a lover or something...

Tobirama hissed softly without sounding anything, and felt his face getting hot under such an untraceable gaze.

"Brother, brother..."

"Don't be afraid, Tobirama," Hashirama said with a smile in his eyes. He leaned down slightly and kissed his forehead first. "Does this feel annoying?"

"..." Tobirama's eyes drifted away, and he quickly replied, "Of course not."

But Hashirama, why would he ask such a question?
He acted as if they were not forced into disgusting intercourse, but were in love and it was a natural thing.

Hashirama lowered his voice: "What about this?"

He naturally moved down and gently bit his brother's lips in a light kiss.

But that was enough to stun Tobirama. Even if he was slow, it was not difficult for him to discern the lingering emotions in this kiss.
Hashirama was never someone who would force himself to act... He really didn't seem to hate this kind of thing.

But Tobirama soon didn't have the energy to think more, and Hashirama deepened the kiss.

He kept his eyes open, looking intently at his brother beneath him, and many images appeared in his mind uncontrollably.

In the previous few days, Hashirama had seen these lips open in a daze, and seen the lips wet with saliva and tears. They had also kissed on the first day, and Tobirama even... wrapped him here, licked, sucked, and finally swallowed his semen.

But that was very different. Their first kiss was like a battle, full of fear and blood. Now think about it, these days at least one of them was tortured to the point of being almost insane, and they hadn't even looked into each other's eyes properly.

Tobirama let out a very slight groan.

The two closest brothers were pressing their skin against each other. In fact, after a long period of joint training and fighting, they were already very familiar with each other's bodies, but the touch at this moment was terribly strange. Arms touched arms, chests rubbed against chests. Tobirama trembled slightly, and he wanted to avoid his brother's kiss, but was gently held on the back of his neck.

"Relax a little, Tobirama," the other party's tone even seemed to be instructing him on martial arts, "Relax a little, or you will get hurt."

But then, how can I...

Tobirama felt very hot, it was all because of Hashirama's high body temperature. They were so close, and Hashirama was licking and biting his lips, making soft kissing sounds. The hot air from his breath was trapped in the small space. Tobirama felt that soft and slippery tongue, his body was stiff like a board, and he felt dizzy.

I don't know when I relaxed my clenched teeth.

Hashirama had expertly pushed this kiss to the point of passionate intimacy. He obviously wasn't supposed to have any experience, but he was able to control Tobirama's body very comfortably, invading his mouth, stirring his tongue that had nowhere to hide, and accepting his brother's sensitive tremors as the contact became deeper and deeper.

"Um... Stop kissing me..."

Tobirama felt very dizzy and he couldn't breathe. Hashirama was like a soft and hot net that tightly covered him. His ears were numb from the entanglement of the net, his fingers curled up and clenched, and then separated at a loss. He never dared to meet his brother's gaze, but finally felt as if there was nowhere to escape.

Thirst burned his blurry mind and his whole body seemed to be burning. Tobirama almost wanted to curl up in the airtight kiss, but in the end he could only rub Hashirama's neck involuntarily.

For a moment he forgot what they were doing, but soon today's clear mission popped into his mind.

"Brother," Tobirama struggled to find an opportunity between kisses, his face was already red, and his breathing was completely disordered, "Don't... don't do these useless things, we have to, we have to complete the task quickly-"

Hashirama glanced at him, his smiling expression didn't seem to change: "Okay."

The elder brother was extremely quick and immediately removed the last bit of cloth from their lower bodies.

His skin involuntarily shuddered slightly when it came into contact with the cool air, and Tobirama was stunned and couldn't help but shrink back.

His eyes, which had been avoiding the view, involuntarily turned downwards, noticing the penis that was exposed after his brother took off his pants. It was really, really...

For a moment, Senju Tobirama was a little doubtful. In addition to the psychological pressure, today's mission would also be more physically difficult than the previous two days.

Hashirama's hand also began to move downwards.

Tobirama's scalp numbed, and he became somewhat aware of his words, which seemed to be an invitation. But Hashirama's warm hand reached the base of his thighs, inserted between his tightly closed legs, and his fingers touched his anus, which had begun to react.

It was actually slightly wet there. Hashirama raised his eyebrows barely noticeably and pretended not to notice.

If I tell you now, Tobirama will be furious, but unfortunately, during the four consecutive days of missions, his body seems to have been subtly transformed.
——It can't be said to be in a bad direction.

Hashirama pressed the corners of his lips, used two fingers to separate the taut buttocks, and tentatively circled his fingertips around the small opening.

Tobirama took a deep breath, closed his eyes as if to cut off his arm, and followed his force to spread his legs a little.

Hashirama inserted a knuckle.

hiss......

With yesterday's experience, he pushed through the warm soft flesh with ease and came to the place that could make his brother lose control. Thanks to the delicate kissing and caressing just now, there was obviously no resistance here like yesterday, and even some natural liquid lubrication seeped out, making his entry smoother.

Tobirama bit his lips hard and closed his eyes, as if this could deny the fact that his brother was playing with his butt.

But the irresistible pleasure still came honestly. The kiss just now seemed to make his body more sensitive. Tobirama could hardly hold back the moan in his throat. Hashirama's fingers pressed on that piece of soft flesh slowly, which made his whole lower body go limp and his legs lost their tension.

He kind of wanted to beg his brother to stop dawdling, to insert it quickly, and then to quickly complete the damn task of ejaculating together, but he couldn't help but think of the size he had just seen... and he had to admit that perhaps his body needed more preparation.

The injury wasn't that terrible, but even Tobirama didn't think he could ejaculate smoothly in that much pain.

The untouched front end of Tobirama's penis slowly rose up, and while Hashirama was exploring his anus, he was stroking his penis while thinking - the key to this mission was "timing", how could two people reach orgasm at the same time?

The number of fingers gradually increased to two, then more. When the number of fingers increased to four, Tobirama's face was already flushed, and he raised his hips slightly uncontrollably to make the difficult swallowing of the anus less painful. He tightly grasped the bed sheet, and the veins of endurance appeared on the side of his neck pressed against the pillow. Finally, he couldn't help but urge:

"It's ok...Brother, please, please come in."

Hashirama paused, he had almost reached his limit of endurance, and after fully understanding his feelings for Tobirama, his resistance to his brother who was soaked in sexual desire seemed to become even weaker.

Hashirama withdrew his hand, which was already dripping with juice, stared intently into Tobirama's eyes, and moved closer with his waist raised.

When the thick head entered, both of them paused in breathing.

Hashirama couldn't help but raise his head. It was really... really, so comfortable.

He had never imagined this scene before. Even though he realized that his feelings for his brother had deteriorated, and even though he had relieved his desire for Tobirama's body, when he actually inserted it into that warm and soft hole, the stimulation of being wrapped so delicately still gave him a shock. The pleasure jumped from his lower abdomen to the top of his head, and fireworks exploded in his brain.

Hashirama grabbed Tobirama's thin waist and thrust hard into him almost instinctively!

"Ah...!"

Tobirama screamed in surprise. Despite a gentle foreplay, the size of the thing that exceeded his tolerance still made him feel like he was almost torn apart. White light exploded in front of his eyes. The thick pillar of meat rushed in like a siege, breaking through layers of intestinal flesh and crushing heavily on the already slightly swollen sensitive spot, bringing extremely strong and continuous stimulation.

The stimulation was simply too much, especially for Tobirama.

In the experiments of the previous few days, he had been forced to endure quite high intensity sexual pleasure, but that was completely different from now.

Those dead objects, or just Hashirama's hand, were completely different from his brother truly entering his body and them truly becoming one...

And at this moment, after a long period of accumulation in the early stages, that kind of hidden desire and rebellious feelings, through the most intimate physical contact as a carrier, suddenly and unimaginably broke out.

Tobirama's waist suddenly spasmed, and he was completely out of control. The moment Hashirama completely penetrated him, he screamed "Brother" and was forced to ejaculate by the intense pressure and satisfaction!

Tobirama couldn't control himself, and neither could Hashirama. His anus tightened the moment his brother reached orgasm, and it made his scalp numb. At first he tried to move as gently as possible, but his lower body moved uncontrollably, and he thrust hard again and again amid Tobirama's helpless moans.

"Ah... Brother, don't, slow down a little bit—ah!"

Tobirama's waist was completely arched, and he wanted to close his legs that were spread out to the sides, but he was blocked by Hashirama who was lying on top of him. His extremely sensitive intestines, which were in climax, kept feeling deep stimulation. He could only clamp Hashirama's waist tightly, but he was constantly shaken by his thrusting movements, and his whole body was like a small boat floating in the raging sea of ​​desire.

But Hashirama simply couldn't slow down. He was swept up by the incomparable pleasure of desire, and he rammed forward again and again in a daze. The more he thrust his swollen cock, the more it was wrapped tightly by the spasming intestinal flesh, and more clear fluid was forced to seep out, making his movements smoother and the pleasure surged up in waves, urging him to thrust more fiercely.

Hashirama thrusted for several hundred times, and finally his eyes went blank and he ejaculated.

A large amount of hot semen was mercilessly shot into the deep of the intestines. Tobirama's voice was almost hoarse. He trembled in Hashirama's arms, trembling with the rush of liquid. His eyes rolled back and he almost ejaculated again.

"no......"

Tobirama still had a trace of rationality left, even though tears were thrown out of his eyes as he shook his head weakly: "Brother, help me... We have to do it at the same time-"

Hashirama was breathing heavily, he hugged Tobirama's body tightly, his lower body still moving slowly and gently, enjoying the afterglow of the intense climax. He squeezed one hand between their two tightly pressed bodies, found Tobirama's penis, which was beginning to flow with excitement again, and blocked the rapidly opening little mouth.

Tobirama's waist trembled violently, and he was speechless for a moment, his collarbone was stained red.

It was not pleasant to be forced to come down from the climax, and Tobirama's nose was physiologically sore. Hashirama began to kiss him again, sweeping the liquid on his face that was either saliva or tears into his mouth, then captured his lips, exchanging each other's breath and body fluids.

Hashirama quickly regained his spirits and they began their second attempt.

After ejaculating once, Hashirama's rationality had obviously returned a lot. He observed Tobirama's condition and thrust slowly and deeply. His scorching gaze and uninterrupted penetration brought him an incomparable and lasting pleasure, which was completely different from the direct and intense stimulation. It was more prolonged because it was slowed down, like a wave that was always suppressed below the peak, surging wave after wave, never stopping.

Tobirama soon couldn't bear it anymore. He was almost collapsed by his brother's abnormally burning gaze today, not to mention the most direct physical stimulation - at this moment, although Hashirama was kind enough not to attack that piece of soft flesh accurately, it was too thick. Every time he pushed deep into it, he couldn't avoid crushing that place hard. Tobirama began to feel the maddening sourness of yesterday again. The blocked front end aggravated the sensitivity of his back hole. He had wanted to ejaculate again, but this time Hashirama was terribly durable. He repeated the thrusting action tirelessly, as if he was determined to squeeze more juice out of the body under him.

Tobirama was indeed leaking water constantly, like a sponge, with water being squeezed out of all parts of his body. Tears made the corners of his eyes red and swollen, and the blocked front end was also slowly leaking clear liquid, especially from the ravaged anus. The obscene sound of water was extremely loud in the empty room. He shivered unconsciously to cater to Hashirama's invasion and kiss, and kept muttering "brother" unconsciously. He didn't even know what he was saying. He just tried hard to avoid Hashirama's gaze that seemed to be cutting him open. He couldn't help but hugged Hashirama's neck and buried his face in his neck like an ostrich.

When Hashirama licked and kissed Tobirama's earlobe, Tobirama cried out. The sticky sound of water was amplified in his ears, and together with the sound of water in his lower body, it was like a sea of ​​desire that completely overwhelmed his reason. Tobirama almost forgot who he was and where they were. He just cried uncontrollably, his waist moving helplessly, as if he was actively responding to his brother's fucking in a lewd manner. The obscene fluid flowing out of his anus was squeezed into a circle of foam, which then dripped onto the bed sheets, covering his round buttocks with sticky liquid.

When Hashirama finally ejaculated again, Tobirama had almost completely lost consciousness. He didn't know when his brother let go of his penis, which had been suppressed to the point of numbness, nor did he know how many positions they had changed. He just spasmed unconsciously when he was burned by the semen rushing deep into his intestines, and his swollen and painful lower body also spit out streams of white semen. They hugged each other tightly, almost merging the two into one, until the "beep" sound representing the completion of the mission was rang out, and neither of them made any other movements.

They maintained such a close posture, Hashirama tightly hugged his most precious brother for a long, long time, and the blurred consciousness Tobirama also instinctively rubbed against his arms.
They are the closest relatives in the world, connected by blood.

13.
"How are you now?" Hashirama asked very considerately, "Are you still sore?"

"..."
Tobirama stared at a certain spot in the void and didn't want to talk.

Now they could finally lie in the bathtub peacefully and clean themselves up. Although this room had a weird self-cleaning function, it was certainly not as good as a real hot bath.

It would be better if you don't have to wash together.

Tobirama began to not understand his brother. It seemed that he was the only one who felt bad about sleeping with his own brother. Is this normal? It's not normal.

It's not that he didn't feel happy during the process or anything, but this is not normal in any way, right?

But it seemed that he was really the only one who was struggling. Hashirama very naturally carried his exhausted brother to the bathroom, filled the hot water, and even squeezed into the small bathtub with him intimately, wiping off the dirt on his body bit by bit.

Tobirama was about to be driven crazy by his attitude.

"... Tobirama?" Hashirama gently put his hand between his brother's legs and touched his forehead at the same time, "Are you okay?"

From the moment he finished today's task to the moment he helped Tobirama finish the cleanup, Tobirama seemed to be avoiding looking at him the whole time.

This shouldn't be the case. Hashirama thought, Tobirama would never treat me like this.
If it was normal, this would be enough to make him dejected, but in this delicate and tense environment, Hashirama still encouraged himself.
He didn't want to show weakness when Tobirama was uneasy.

He stubbornly turned Meijian's head and asked him to face him.

"...Our mission is going well so far," Tobirama's eyelashes trembled, his eyes wandered and tried to dodge, and finally he said weakly, "Brother, tomorrow is the sixth day, and we have already completed half of the time."

Hashirama blurted out: "I'm not talking about the mission, I'm talking about you, Tobirama, you were also..."

"I don't."

"Nothing?" Hashirama was stunned. "I don't understand, Tobirama, look at me, don't you like-"

"Shut up!"

The silent young man suddenly exploded, Tobirama raised his eyes, although he was often so impatient in daily interactions, but today he looked really different from usual.

Their gazes disappeared as soon as they met, and Tobirama's deep red eyes seemed to be burned and suddenly looked away.

"I'm not..." He became weak again after being angry. "Stop talking, brother."

The air was filled with a silence as heavy as steam, and for a moment there was only the faint sound of running water in the bathroom. After a long moment, Hashirama touched his brother's head and resumed cleaning him.

This time, Tobirama simply closed his eyes, and Hashirama almost thought he was asleep, but his brother suddenly spoke.

Tobirama lowered his eyes, as if trying to keep his tone straight: "If what we did was a joke, it would be a bit too bad, but if it was revenge or torture, it seems meaningless."

Hashirama could understand what he meant.

Option A every day - the one targeting him, those requirements are indeed very bloody and harsh, but option B, how to say it, Tobirama was indeed tortured badly, but those actions would not cause irreparable harm.

Even Hashirama was a little relieved and thought: Fortunately, the two of us were imprisoned here together.
He couldn't imagine if it was another person... who would do those things to Tobirama.

Tobirama was also talking about this: "Especially between the two of us, brother, it becomes, becomes bearable."

When he said these words, it must have been difficult to see from his expression, but he was forcing himself to say them. It was some kind of confession - not the kind that Hashirama expected.

Tobirama took a deep breath and said, "Although it would be extremely unbearable to be seen like that by my brother, but because I think of him as my brother, it seems that there is nothing that cannot be seen."

They were pressed very close together, their bodies filled with each other's body temperature and scent, and Hashirama was washing Tobirama in the most intimate way. His fingers were twisted in the hole that had just accommodated him, moving in and out gently, soothing, while Tobirama leaned on him, his open legs still a little tense, his legs trembling slightly, but after all, there was not much resistance.

Tobirama looked as if he had done something extremely outrageous and no one else mattered.

Hashirama hesitated. He didn't think that Tobirama was in such a good state, but he didn't want to push him too hard. He was the one who had feelings for his brother first, so it seemed that he should give Tobirama some time to figure it out.

But one thing still needs to be corrected.

Hashirama held Tobirama's chin and turned his face back to the side without question.

"Look at me, Tobirama."

Tobirama's eyelashes fluttered twice quickly, and then closed in a huff, as if deliberately not letting his brother get his wish.

Hashirama grinned, but continued as planned.
"There's no such thing as 'unbearable'. That's not an unbearable thing," he said very directly, "I like it very much."

Tobirama couldn't help but open his eyes: "......?"

"Ah, that's not it," Hashirama added quickly, "I'm not talking about the time when you were tortured very hard. I mean, um... I'm sorry." He coughed dryly, and his voice became weaker, "But it was indeed quite, quite - quite beautiful at that time."

Tobirama's pursed lips relaxed, but his expression could not really be described as "happy".

"Are you saying this for Konoha, brother?"
Tobirama even began to put on a businesslike face: "To get out of here? I know you are always an optimist, but you don't have to go to this extent."

"Part of it is for Konoha," Hashirama smiled and scratched his head, "but the main reason is that I really like Tobirama."
He thought for a moment and said it again in a more precise way: "Even if I'm not here, I still like him very much."

Senju Hashirama has this kind of personality. Even if he feels that his brother does not have the same thoughts as him now, he never feels that his feelings need to be concealed. He frankly takes out his heart and shows it to Tobirama.

Tobirama's hands under the water suddenly tightened.

An incredible feeling of strangeness suddenly filled his chest. Although he had already made some guesses during today's mission, these words coming from Hashirama's mouth were still completely...

When he had been looking at his brother's back, he never thought that one day he would hear such words.

"But now, we still have to focus on getting out of here," Hashirama patted his brother's shoulder with relief, and added: "For Konoha."

Chapter 8

14.
I slept exceptionally well that night.

Maybe he was really tired yesterday, or more importantly, after several days of continuous torture, he finally had enough time and mental rest. When Tobirama opened his eyes again, he felt incredibly energetic.

The two brothers woke up almost at the same time, and Tobirama then found himself almost lying in Hashirama's arms. The clear distance between them in the past few days was removed, and the two quilts were mixed together, and Hashirama used his hands and feet to take him entirely for himself.

Tobirama cleared his throat, "Wake up, brother."

Hashirama let out an ambiguous grunt and rubbed his chin hard on his brother's head, making his silver hair even more messy, before finally opening his eyes in satisfaction amid Tobirama's protests.

Today's mission flashed on the TV screen as usual.

[Day 6
A. Ask experimenter B to cut off both palms of experimenter A.
B. Ask experimenter A to use the props provided on experimenter B. Before the task is completed, experimenter B cannot ejaculate. (Note: 1. The task duration is 4 hours and 25 minutes; 2. During the experiment, experimenter A shall not use props, limbs, etc. to physically block the genitals of experimenter B, and shall not deliberately delay the use of props; 3. During the experiment, if there is any violation, experimenter A will be punished. The punishment is cumulative and irrevocable, and will stop automatically after the task is completed; 4. If either party dies during the experiment, the experiment will stop automatically.]

The text description of this day was very long. Before he read the content clearly, Tobirama had already had a bad feeling in his heart. After reading those long annotations, he even felt a slight fear.

The last note is a stark threat.
Who will die?

His hands suddenly felt warm, and Hashirama held him tightly from behind, saying in a gentle voice, "We choose B."

"Brother," Tobirama's voice trembled. He turned to look at Hashirama in panic, "I'm not sure..."

"I'm sure," Hashirama said with a smile, "I can trust you."

Tobirama's lips were pursed tightly.

In this round, Hashirama's life depends on him. What if this is a trap? Option A, which looks hideous and sinister on the surface, still has a glimmer of hope. But option B requires him to suppress ejaculation without any external force during more than four hours of teasing. Is this possible?

There will be punishment every time, and the punishment will be accumulated... Tobirama's hands trembled.
It's not that he has no confidence in his self-control, but the physiological reaction is not something that self-control can control.

Compared to the anxious Tobirama, his brother's voice was full of energy.

"Challenges will never be easy, Tobirama," Hashirama began to study the props on the table, "But don't worry, this is not a battle for you alone. I think this is a task that requires our joint efforts to complete."

Hashirama was right. The experiment required him to use all the props here on Tobirama, but he was the one in control of the props. If he could control them well, he could help Tobirama to the greatest extent.

What if I mess up the usage of the props? Hashirama suddenly had a wild idea: the experiment didn't seem to stipulate how to use these things, what if - for example, the massager and the vibrator were only in Tobirama's hands?

Before he could think deeply about this loophole, the room seemed to have sensed Hashirama's thoughts, and a [Supplementary Explanation] suddenly popped up on the screen.

[Additional Note:
This task is followed by a "Props List and User Manual". Please make sure that there are no omissions and no mistakes in the use of the props when completing the task, otherwise the consequences will be at your own risk.]

Hashirama looked at the densely packed rules in the manual and sighed with some regret.
Well, Tobirama will still have to suffer a little.

In order to gain more rest time, after deciding on the option, Tobirama did not hesitate any further. Perhaps he still felt that a punishment that could be avoided as much as possible was better than having his hands cut off directly.

Hashirama doesn't have a sage body here, and they don't have decent medical methods. With a serious injury like a cut hand, he would die from excessive blood loss in less than four hours.

Tobirama lay down with a heavy heart.

The two brothers were already very familiar with taking off clothes, and Hashirama also took off all his clothes without much need. Tobirama looked at him and said nothing.
But this did make him relax a little.

First up is a piece of soft silk.

The screen started counting down when Hashirama picked up the silk, and the first step of the operation guide was thoughtfully displayed.

"Well..." Hashirama gestured to his brother, "I'm going to cover your eyes first."

Tobirama's voice was a little sharp: "You don't have to explain it to me, brother."

He was lying straight on the bed, his hands on both sides, as neat as a corpse - and pale as well.
Thinking of this, Hashirama gently covered those beautiful red eyes with silk. He felt a little sorry that he couldn't use his eyes to comfort his poor brother during the whole process today.

After completing this step, Tobirama became even more rigid.
His vision was completely dark, which was different from the feeling when he closed his eyes on his own initiative. The helplessness of being forcibly deprived of his vision was terrifying.
Tobirama felt his hair stand on end, and Hashirama's warm skin rubbed against his waist and abdomen, making that place feel like it was electrocuted.

He could feel his brother picking up the second thing. Good, now he no longer introduced each item like a street vendor.
But Tobirama gritted his teeth. He couldn't see what it was. Instead of feeling the unknown with his body, he might as well hear it directly.

Whatever it was, Hashirama didn't rush to use it. Instead, he lifted his brother's chin and gave him another long, deep kiss.

Tobirama's breath was choked.
Hashirama's body temperature was the only thing he could trust in the darkness he was in. Visual deprivation made his reaction slow and his sense of touch more sensitive. Tobirama opened his lips slightly at a loss, allowing the hot and slippery tongue to invade his mouth. He couldn't keep up with Hashirama's rhythm. His tongue was numb from the rough but extraordinarily strong sucking and licking. A cluster of fire seemed to be ignited, flowing from his chest all the way to his lower body. He even felt his lower body slightly raised.

No......

Tobirama was stunned for a second, then he was startled and suddenly used all his strength to push Hashirama away.

"No...!" He panted, with transparent and sticky liquid still hanging on his lips, but he refused firmly, "Don't do this, brother, not at all!"

Hashirama frowned: "It's just necessary foreplay, Tobirama, you will be uncomfortable."

"Don't you understand?" Tobirama's brows were even tighter than his, and his authority was not diminished by a piece of silk. "What does it matter if I'm uncomfortable... No, you should make me more uncomfortable. Remember, don't, don't climax!"

"You could be hurt—"

"It's just a minor injury that will heal quickly," Tobirama insisted, "It won't be more serious than the consequences of your reckless behavior!"

He couldn't see it, but Tobirama was too familiar with Hashirama. After just a moment of silence, he could imagine that the other person seemed to have even his ears drooping, like a large dog being trained.

A sudden burst of force hit Tobirama's shoulders, and he lost his balance, fell backwards, and fell into the soft bed.

When he felt his legs being pulled apart, Tobirama even breathed a sigh of relief.

Hashirama's movements were still gentle, but he did remove a lot of unnecessary frills. Tobirama gritted his teeth, and the fingers that he had been forced to become familiar with in these days had reached his anus. His fingertips were dipped in the cool and slippery oil, and they were rotated and poked inwards.

If possible, Tobirama thought, he didn't want Hashirama to lubricate him at all.

He can feel some pain, the more pain the better, pain is the most direct way to suppress sexual desire, but unfortunately Hashirama will not allow it.
There is no need to discuss this at all, Tobirama agrees with Hashirama's way of protecting himself, just like Hashirama agrees that they always choose B.

The feeling was still weird, something rough and not belonging to this place was inserted into the anus. The finger rotated and dug forward, but compared with before, it obviously avoided the sensitive area deliberately.

But it is impossible to avoid it completely, not to mention that after the "training" of the past few days, just the "insertion" itself makes this body slightly excited.

Tobirama's breathing became a little faster, and he tried to calm down, trying not to think about how his brother's fingers were stirring in his ass.

The finger was withdrawn, and replaced by a round...vibrator?
Tobirama tried hard to distinguish it. The round and hard thing was not big, and was easily swallowed by the anus, but it still had a strong presence in his intestines. As if attracted by the suction from deep inside, it slowly slid in, until it reached the well-protected raised soft flesh... Suddenly, a strong vibration broke out!

"Ah...!"

Tobirama screamed out unexpectedly, his pubic bone was numbed and his eye sockets felt sore immediately, but the vibration was not instantaneous, but continuous and even increasingly strong.

Ahhhh...

Tobirama turned his body sideways and couldn't help hunching over, unable to even scream for a moment. The vibrator that was pressing against his sensitive spot and vibrating wildly made him miserable. Intense numbness, itching and tingling broke out from deep within his body. His head felt like it was pricked by a needle and his lower body felt a familiar soreness.

No, no—

Tobirama clenched his fists, digging his nails into his palms, and endured the wave of painful pleasure, shouting hurriedly: "It's OK... I'm OK, brother, use the next one!"

There is also an item in the task notes that says "no delay", so don't take any risks.

Hashirama's worried voice finally rang out: "Are you sure?"

"quick!"

Two more vibrators were attached to the nipples that had already stood up automatically. Tobirama was stunned. Before he could react why it was in this place, he was overwhelmed by a new and crazy tingling sensation.

The vibrating little thing pressed tightly against his chest. The presence of the two points on his chest had never been so strong. The pleasure was like a spike piercing his brain. Tobirama twisted his body unbearably. The tingling made him feel like a small insect was drilling in, and like a whip was hitting him. He wanted to lie down and rub his chest against the sheets under him...

The warm rod touched the shrinking hole behind him at this moment. Tobirama tried his best to control his muscles, feeling the thing stretching the flesh hole that had not been properly expanded yet, bit by bit, and poking it in slowly but firmly.

It was too slow. The slow entry did not bring any pain at all, but made the pleasure even more unbearable. All the senses seemed to be stretched by the stickiness, like scratching an itch through a shoe. The desire to break through that layer of window paper burned like a raging fire.

"Haaah... Don't, don't do that... Hurry up!"

Tobirama no longer had time to think about how he had taught his brother step by step to play with his body. He just wanted this damn desire that was about to reach the peak to be pulled down a little bit. He was almost driven crazy by the two extreme desires in his body: his physiological instinct wanted to reach orgasm at all costs, while his reason was fearfully trying to extinguish the fire of desire.

How is this possible? This is too difficult...

Hashirama hesitated for a moment, but decided to listen to his brother and exerted force on his hands.

Tobirama let out a hissing sound, and he finally felt a little precious pain, which successfully offset part of the pleasure and gave his drowsy brain a shot of clarity.

But this Qingming Festival is too short.

The fully inserted massager began to rotate without warning, just like those vibrators, which were turned to the maximum without any buffering. The thick and long rod danced wildly in the soft intestines, rushing towards all the sensitive points that could not bear the burden.

"Uhhh..."

Tobirama's body bounced, he was totally at a loss, the desire that exploded in an instant was like a raging fire that burned all the weeds, his legs began to spasm, his waist couldn't help but thrust forward... No, I can't do this, I'm really going to cum, I really can't hold it back anymore.

According to the mission notes, Hashirama can't even help him block it or...

A light suddenly lit up in Tobirama's mind, and the solution that had been blocked for a long time by his slow thinking jumped into his mind. He bit down on the tip of his tongue without hesitation.

"......"

"Tobirama!" Hashirama keenly sensed something was wrong. Tobirama's body, which was clearly on the verge of collapse, suddenly felt like it was stabbed. He was clearly ready to accept the punishment, but the head of his brother's hard and red penis actually relaxed a little.

He held Tobirama's face in his hands. Tobirama blinked weakly, and a streak of dazzling red flowed out from the corner of his mouth, which he could not close tightly.

Hashirama's face changed, and he used two fingers to pinch open Tobirama's mouth, and sure enough, he saw a mouthful of blood.

"You..." The brother's rare anger rose up, "Who told you to hurt yourself!"

"It's okay," Tobirama's voice regained a little calmness, "I have... control, it won't bleed for too long."

"It's a lot lighter than your punishment, brother."

Hashirama was speechless for a moment, but he still said solemnly: "Only this time, Tobirama, the time is more than halfway, we are almost successful, if there is a punishment next, I can still hold on until the end of the experiment."

The eyebrows under the silk raised slightly: "Has the time really passed halfway?"

"certainly."

Tobirama didn't have the energy to pursue the matter for too long. The precious clarity brought by biting his tongue only lasted for a short time, because Hashirama had to replace the props on him and added even more excessive things.

When the cool liquid just touched his anus, Tobirama thought he had a moment of respite, but before he could catch his breath, the burning desire burst out from the place where he was breached, burning like an explosion in an instant.

That is... an aphrodisiac!

Tobirama cursed inwardly the pervert in the room, but the thought only flashed through his mind before his mind went blank and he couldn't control his orgasm at all.

During those two seconds of climax, Tobirama simply lost control of his body. He couldn't even perceive his own body. He seemed to be floating in the clouds, feeling nothing except pure happiness.

But soon, that light consciousness was bound back to the body, and he began to feel the sudden rush of heat, the sore waist and legs as if almost shot out, and the body still unable to control the spasms. The semen flushing the fragile urethra brought another level of intense stimulation. He didn't know how his eyes were rolling back with tears under the silk, his pubic bone twitching so hard that it hurt, and even his toes were stretched to the limit, as if his brain was being hammered continuously by a heavy hammer.

However, at the same time, the smell of rust began to spread in his nose, and a little warm and sticky blood fell on his arm - judging from the smell, it was obviously impossible that there was only that little bit.

"...Brother?"

Hashirama did not answer. In those brief few seconds, unspeakable fear spread in Tobirama's heart, but he did not dare to take off the blindfold at all, for fear that the violation would bring more punishment against Hashirama. But Hashirama had obviously avoided him. He grabbed desperately in the air, but could not catch the familiar body. The body temperature that was so close just now quickly disappeared, as if everything was just an illusion.

His body was so limp that he couldn't even get up. Tobirama tried desperately to turn over. His lower body was even still spurting out small streams of semen. His tears soaked the entire silk. His knees were shaking so much that he couldn't kneel at all. The props were still moving diligently on his body. The massager in his anus was spinning wildly, making that muddy hole splatter with juice.

Tobirama's lips trembled, but no sound came out. His fingers turned white from exertion, and he crawled forward on his knees, groping around aimlessly but persistently.

"Brother, brother... answer... me, how are you...?"

A hand grasped his.

"It's okay...it's okay."
Hashirama's voice sounded unstable at first, but he soon forced himself to stabilize. Tobirama could hear the weakness in it, but fortunately, he was still conscious and sounded able to hold on.

Hashirama himself said the same thing: "It's just vomiting blood, that's all - we all have to eat better tonight."

Tobirama trembled in his arms, uncontrollably uttering small whimpers and screams from his throat from time to time. Fortunately, this wave of climax was considered a punishment. When he finally fell into the refractory period and his penis finally softened a little, Hashirama said comfortingly: "There is not much time left. You can do it, Tobirama."

But the new round of endurance became even more painful.
The first cycle consumed too much energy, so much so that Tobirama felt weak even breathing at this moment, and when the new toy was placed in his body, he could only shiver slightly.

His sore waist and knees made him even less powerful, so Hashirama made him lie on his back on the bed with his legs wide open. Tobirama let him do whatever he wanted, and all his energy was used to control his pathetic lower body.

He was still constantly worried about Hashirama's situation - which couldn't be considered a bad thing, as it was a way to divert his attention.

But the body's instinctive reaction was too hard to deceive, Tobirama could feel his body gradually heating up again. He was getting hotter and hotter, and as the time of suppression prolonged, countless beads of sweat flowed out. He lay there, feeling like he was about to melt.

But it couldn't melt, at least not in that part.

It finally became a battle of wills. Tobirama would often lose consciousness, forgetting what he was enduring so painfully, but would soon wake up in horror and anxiously search around him for Hashirama's scent - he could feel that Hashirama was also gradually weakening.

They cannot afford to be punished again, absolutely not.

Thoughts were like tiny cotton wool connected by spider silk that would break if pulled. Every cell in his body was about to boil, but was forcibly suppressed below the boiling point. The props were humming tirelessly, ready to stimulate his nerves that were so tense that they were about to break. Tobirama didn't know what he was shouting. Maybe he was begging for mercy, or maybe he was just crying meaninglessly. He was about to collapse completely, and his whole body was spasming continuously. If permission was granted, he thought dazedly, maybe I should shoot my brains out.

When the change happened, Tobirama didn't react for a long time. The deafening tinnitus in his ears prevented him from hearing Hashirama calling his name, telling him that everything was over, nor could he feel the torture instruments being peeled off his body bit by bit.

Until his familiar, trusted, erect penis belonging to Hashirama was deeply penetrated, and he even felt the tingling pain at the sensitive spot when the vibrator was finally stripped off.

"Brother..."

"It's okay, it's okay, Tobirama, shoot." Hashirama peeled off the silk on his brother's eyes and kept kissing his eyes and red nose. He moved his lower body skillfully and gently, making the man who was about to break bury himself deeply in his arms and move in rhythm with his movements.

Tobirama's eyelids slowly closed, and as physiological tears rolled down his cheeks, he seemed to have finally regained some clarity.

Low moans and whimpers rolled out of his throat. His expression seemed as if he felt aggrieved, but also as if he was surprised. His whole body softened in his brother's arms, and starting from the waist, he suddenly began to shake violently, like a leaf in the wind. Hashirama almost couldn't hold him for a moment.

But Tobirama was finally spared from the long punishment. The moment he realized the fact and that it was Hashirama who was fucking him, he completely lost control and ejaculated. Streams of semen washed his penis until it became red, swollen and sore, and even his buttocks were spasming wildly from the exertion. He simply didn't need any extra caresses at this moment. The pleasure that had accumulated over a long time and was forcibly suppressed suddenly erupted like a spring. Tobirama was so happy that he even forgot who he was. The only thing on his mind was ejaculation. The semen that was ejected went from being thick at the beginning to gradually becoming thinner, and in the end, even light yellow urine was dripping out along with it.

Hashirama held him the whole time, amidst the pool of blood, semen, and tears on the bed.

Chapter 9

15.
"I'm so..." Tobirama lowered his head, "I'm so sorry."

The sixth day's mission has been completed. Thanks to today's time limit, it actually ended a little earlier than usual.

After they cleaned up everything, they even had a sumptuous afternoon tea.

The room was thoughtfully prepared with some blood-replenishing ingredients. From this perspective, the tendency of this place was becoming more and more confusing.

But it was obvious that Tobirama was not very interested, whether it was the exquisitely made pastries or the hot and sweet brown sugar ginger tea.

"Don't think like that, Tobirama," Hashirama hugged him, "It's all thanks to you, it's always been thanks to you."

Hashirama Senju's words came from the bottom of his heart. Ever since he was trapped here, he was the one who should have been protected, but instead, it was Tobirama who had been working hard to complete the task.

Thinking of this, Hashirama, who was the one who comforted him, became depressed.
He was even more dejected than Tobirama: "It's all my fault that I didn't protect you well."

Tobirama: "..."

Okay, the guilty atmosphere was suddenly gone.

But they still spent the afternoon more quietly than usual, and Hashirama seemed to be recovering well - in terms of blood loss, Tobirama observed that it was at least recovering faster than the first day when he was punished.

Does this mean... he couldn't help but wonder, Hashirama's sage body, or his chakra, is recovering at a very, very slow pace?

If that were the case, it would be great. If they had some self-protection ability, their situation would not be so passive.

There are still four days left.
On the bright side, there are still four days left, maybe they can get out.

When he woke up on the seventh day, just by looking at his face, it was completely impossible to tell that Hashirama had lost a lot of blood yesterday. He closed his eyes and carefully sensed for a while, and actually connected to a little bit of weak chakra.
His body was indeed slowly repairing itself!

This made both brothers feel a little excited.

Until they could see the words clearly on the TV screen.

[Day 7
A. Ask experimenter B to cut off experimenter A's arms (Note: they must be cut off at the shoulder blades).
B. Ask experimenter B to confirm experimenter A's identity from three subjects through sexual intercourse while being deprived of vision (Note: 1. The three subjects will be carried out at the same time, and the positions and actions of each round will be randomly assigned by the room and cannot be changed at will. 2. During the process, experimenter A must not make any sound to communicate. 3. If the wrong choice is made, experimenter B will be punished.)]

Tobirama felt seized by an inexplicable panic.

What does "three subjects"... mean...?

Hashirama's face suddenly turned bad. If he had not been deprived of his ability, the chakra that overflowed from his body with anger would have turned the entire room into dust.

But before he could say anything, he heard Tobirama's voice quickly say, "Let's choose B."
As if afraid that he would act impulsively.

"Tobirama, no!"

Hashirama seemed to have been punched in the face: "I disagree! Wait - we haven't made a final decision yet."

The second half of the sentence was addressed to this room - whatever it was, and the suspicious entity in charge of this experiment.

The room was politely silent. According to the rules, the daily option selection was supposed to be decided by the two experimenters.

Tobirama raised his head. If he had been deliberately avoiding his brother's gaze since yesterday, now that their eyes were fixed on each other, he had completely forgotten that.

"Let's choose B," he said to Hashirama in a tone that left no room for negotiation, "Have you forgotten our goal, brother? We have to survive these damn ten days and get out of this place together."

"Damn it, Tobirama, but there's no way I'll let anyone else..."

"That's nothing." Tobirama's expression failed to successfully express "nothing", but his voice was firm, "I won't die. Remember, all the experiments on me will not let me die."

But that is...

Senju Hashirama was not good at arguing, but he would never agree with his brother's sophistry.

"......或许我也不会，"柱间最后用尽量轻松的语气说，"你没有发现吗？不知从什么时候起，我的肉体损伤恢复速度加快了，现在我甚至能感受到一点查克拉的存在，或许这个实验的规则就是这样——在后面几天里，我们可以进行更多样的选择。"

Tobirama still shook his head. It wasn't worth the risk.

He pondered how he could convince his brother - usually he was good at it, but when Hashirama was really stubborn, things were different.

At this moment, the words on the screen suddenly changed.

[Task Tips:
To ensure the smooth progress of the experiment, some restrictions on experimenter A are lifted. Experimenter A can use 2 wooden clones (Note: 1. If you choose to use them, experiment A will be forced to execute after experiment B fails 3 times. 2. If experiment B is successfully completed, the skill authorization can continue to be retained). ]

Both of them were stunned.

Hashirama's eyes lit up, "This is the first time the experimenter has set up a 'reward' for us."

His resistance to option B was instantly reduced a lot. If it was his wooden clone who was doing the operation, the torture that
Tobirama would obviously be reduced a lot, both physically and psychologically.

It was Tobirama who began to hesitate at this moment.

There were only three choices. If he made all the wrong choices, why would Hashirama still be punished in the end?
Simply restoring the ability to use the wood clone would not save his life.

"Let's do this," Hashirama patted Tobirama's shoulder, "We don't have any more choices. Besides, I think I can always trust you, Tobirama."

16.
Tobirama was no stranger to being forcibly deprived of his vision, but the panic it brought this time was many times stronger than before.

From now on, he cannot see, and Hashirama is not allowed to make any sound - and he must distinguish his brother's true form from three identical "Hashirama".

Tobirama couldn't help but tremble. He was forced to amplify all his senses to the limit. Any escape was not allowed, otherwise, the price might be Hashirama's life.

A pair of hands were placed on his bare chest.

It was Hashirama's hand, and Tobirama realized immediately that he had become extremely familiar with Hashirama's touch over the past few days.
The size and shape of those hands, the force with which they kneaded his muscles, and the slightly rough touch of their fingertips.

The hand gently circled on Tobirama's strong chest muscles, and suddenly pinched the sensitive nipple, gently pinching and poking the erect nipple.

"ah......"

My brother had never played with this place like this before. The warmth of the human body and the stimulation brought by the vibrator are different. Tobirama's scalp was numbed by the strange touch, and an electric-like pleasure surged from the place of contact and rushed straight to his lower abdomen.

This is not my brother... He thought nervously between his breaths, my brother has never been like this.

But immediately, a completely different thought came to my mind: But could it be that my brother was hinting at something through his abnormal behavior?

In the darkness, more heat sources appeared, and familiar body temperature and breath appeared in three directions at the same time, like an airtight net, pressing down on the captured prey.

One of them was obviously concentrating on playing with Tobirama's breasts, with both hands covering his chest, squeezing and kneading the full chest muscles, and fiddling with the bright red bulges with his fingers. Tobirama couldn't help but want to shrink back, but the man didn't let him go, and even replaced him with his lips and tongue - the wet touch covered the entire nipple, sucking, biting and pulling, and actually sucked out a sound of water.

Tobirama wanted to shake his head to resist. He didn't know whether this was what his brother really wanted to do, or whether it was an action made by the wooden clone under the control of the rules of the room. He couldn't help but hesitate between refusing and taking it seriously.

But at this moment, another pair of hands held up his face, and Tobirama was forced to raise his head. The other person kissed him in the dark, entwining his lips and tongue in a way he was familiar with, deftly wrapping his tongue and taking care of every sensitive point in his mouth with ease.

The resistance was turned into an indistinct whimper, and Tobirama tilted his head back uncontrollably, a movement that caused his chest to naturally thrust forward, as if responding to the play on his chest.

At this moment, the naked knee pushed open the tightly closed legs from behind.

Tobirama almost staggered. He was originally kneeling on the bed, but his upper body was forced to straighten up. His knees were the only thing that could keep him balanced. This balance was broken by the attack from behind. His thighs spread apart and the man behind him took the opportunity to grab his thin waist.

No......

Tobirama's mind was dizzy, and he suddenly realized how he would be treated.
He suddenly realized that one Hashirama was enough to make him completely confused and unconscious in the sea of ​​desire, but what would three Hashirama bring?

But he could not make any substantial sound: one person gave him a deep kiss that suffocated him, one person developed the sensitive points on his chest to the limit, and one person kneaded his buttocks, and his fingertips circled the edge of his shrinking anus twice, then penetrated in along the natural wetness, pressing and kneading the soft and hot intestinal wall in circles.

All of this completely engulfed Tobirama.

The first one to enter was the one who brought the kiss.
Tobirama was already breathless when his lips were released. He thought slowly for a while, whether his brother's kissing skills had always been so superb. Before he could come to a conclusion, a pair of hands firmly pressed the back of his neck, forcing him to bend over and kneel in a rather shameful posture. When he adjusted to the right height, a thick, fishy cock slapped against his dazed lips, pushed open the soft thin lips, and stabbed straight in.

"Uh no..."

Tobirama was stunned at that moment. Except for the first day when he almost semi-forced Hashirama to serve him in this way, they had never done this again.

The overly thick penis completely filled the narrow mouth, and Tobirama was forced to open his mouth wide. The pain of suffocation and humiliation made his mind go blank. The penis only gave him a short time to adapt, and then it smoothly thrust in and out of that wet and soft place. The huge glans nailed the throat every time. Tobirama couldn't help but want to retch, but the contraction of his throat even pleased him, and the thing grew even bigger.

This can't be a real brother.

At the same time as this thought appeared, the little hole behind her that had been developed through foreplay was also brought close to the heat source. The fingers finally stretched open the wet and soft hole. The intestinal fluid that was stirred out had covered it with a layer of hidden watery luster. The hard penis poked the wet and slippery hole shallowly a few times, and then thrust the whole thing in at once.

"Oh...haha..."

An unbearable sound was squeezed out of Tobirama's throat, and he was rushed forward, but the broad chest in front of him was like a warm wall, and he was knocked into the arms of the man in front of him, making the cock in his mouth penetrate deeper for a moment, and that thing seemed to be stabbing into his throat, shattering all the moans that could not be uttered.

The two men moved rhythmically, one after the other, and Tobirama's body swayed back and forth between them, making him feel like an overused sex toy.

But the third man was not to be outdone. He left Tobirama's nipples, which were tortured to be red, swollen and erect, pulled up one of his hands, and forced him to hold his equally erect penis.

The balance that he had maintained with great difficulty was lost again. Under attack from both sides, Tobirama could not support his body with just one hand. He grasped at the air a few times in panic, and was completely brought into the rhythm, like a leaf swaying in the wind.

The familiar penis was thick and hot. As Tobirama held it, he felt the man lying on his back, facing him, and taking his lower body, which had stood up without him knowing, into his mouth.

"......"

Tobirama wanted to gasp for air, wanted to scream, the stimulation of desires from three different sources was about to drive him crazy, but everything was tightly wrapped in the hot and stuffy web, and he could hardly make any sound.

The man behind him attacked the maddening bulge deep in the intestine with familiarity. Every time he slammed into it, Tobirama had the illusion that he was being strangled by the neck and thrown hard into the tide of desire. The sticky and obscene sound of water filled his sense of touch and hearing, making it difficult for him to breathe. At this time, the pleasure from his lower body being sucked was as vivid as a sharp blade, cutting through the hot and trembling flesh one by one, and electric currents danced on the exposed nerves.

Even the roughly treated mouth gave rise to a strange joy. The feeling of being deprived of breathing and out of control was compressed to the extreme. Extreme chaos exploded in waves in the suffocating chest. All the stimulations felt by the body seemed to be stretched out densely. The senses and thinking became dull at the same time. Each stimulating electric current flashed fully at a slow speed, overlapping each other, slowly sweeping into a storm that swallowed everything.

Tobirama didn't notice when he ejaculated. When he regained consciousness, he found that his time was "paused".

That was not a sensory metaphor. Everything around him - including the breathing of Hashirama and the wooden clones, or the flow of air in the room - stopped. Time was only flowing for him.

A voice without any emotion appeared.

[Ask experimenter B to make the first choice, identify experimenter A, and hold his hand]

The pleasure was swirling like a storm in his mind, and Tobirama heard these words clearly in the midst of that storm. An unknown warning glowed red in his consciousness.

My brother's true form?

How could he tell the difference? Tobirama was extremely confused for a moment. The wooden clone was a complete replica of his brother even in the smallest details. They were three... exactly the same clones.

The only difference may be the emotional connection between her brother and herself.
But which one will it be?

Not the one in his mouth, Tobirama thought, his brother clearly resisted such behavior.
But he also thought that the experimental rules "positions and actions are randomly assigned by the room", maybe his brother had to play such a role.

Is it the one behind them?
That kind of gentle and efficient foreplay is familiar to them, but in the past few days of experimentation, with the whole room "watching", it is not difficult to make a subtle imitation.

Or the one with his hands?

in the end......

[Warning: Please make your choice within 1 minute, otherwise you will automatically enter the first round of punishment.
Countdown: 55, 54, 53...]

No...
Tobirama's mind seemed to be filled with bizarre neon lights. Although the three attackers were still, the afterglow of pleasure and climax continued to ferment in his body. In this situation, thinking was simply a luxury, let alone distinguishing the extremely subtle differences.

But, maybe there is...
The thought only lasted for a moment, and Tobirama didn't dare to think about it deeply: he seemed to feel a unique, soul-melding love at a certain moment.

But this fleeting thought was subconsciously ignored, and the subconscious fear and retreat instantly buried it deeply - if it was true, it would represent a complete and thorough subversion of his view of his brother and the relationship between the two of them.

[Warning: Please make your choice and hold the main character's hand.
Countdown: 21, 20, 19...]

Wait, wait...

Tobirama felt a panicky burning sensation, sweat dripped from his eyelashes, and even the blood in his body almost evaporated in the extreme tension.

Which one is it?

【5，4，3......】

Tobirama's eyes went blank, and he was almost at a loss as the deadline approached. He reached out his hand tremblingly and tightly grasped the first hand he could touch.

His heart almost stopped.

And time resumed flowing at that moment, like a stage of water flowing that seamlessly connected with the previous one, the intense stimulation of sensitive points all over the body came back, and the two people in front and behind ejaculated at the same time, and a large amount of semen was poured into Tobirama's stiff body, as if a heavy hammer was hitting him in the face, and he was uncontrollably knocked into someone's arms, sweat and tears poured out at the same time, and Tobirama's whole body was shaking, not knowing whether it was because of pleasure or fear.

He heard the inorganic voice:
[Wrong choice]

17.
Tobirama hadn't even come to his senses when he was helped to put on a terrifyingly shaped dildo in the dark.

The afterglow of climax and fear washed over his mind like a tide, making it difficult for him to regain his judgment in a short period of time. The first thing he felt was a slight pain, followed by a feeling of nausea caused by being stretched to the limit and over-filled.

Tobirama finally felt the touch of wood. His weak arms were holding a thick wooden pillar, and his legs were spread apart by something like a wooden barrel - or a horse's back. He sat on that unknown thing, and his anus was stuffed with one thing after another. Tobirama didn't want to think about how terrible the thing was.

In a trance, certain memories were evoked in him. This thing was strangely similar to... the wooden horse he played with in his short childhood when he was very young.

At that moment, Tobirama even laughed a little, thinking how could that be possible.

He remembered that this was a punishment for his first wrong choice and tried hard to cheer himself up.

It doesn't matter, I will definitely make the right choice next time.

But he didn't expect that the punishment would be so severe and sudden.

To Hashirama, who was forced to remain silent and unable to make any unnecessary movements, the scene before him was a little too exciting.

It turned out to be a real wooden horse, but of course it was different from what flashed through Tobirama's mind.

After the thing was placed in Tobirama's body, it began to shake wildly. The hideous massager standing upright on its back filled his back without any space. The soft intestines were stretched to the limit, and even the wrinkles were almost smoothed out. The powerless posture of Tobirama, under the influence of gravity, made it penetrate to an incredible depth.

From Hashirama's angle, he could just see how the red intestines were forced to stretch open and then violently reinserted while shaking. It looked like Tobirama couldn't even scream. His whole body was shaking and twitching, with streams of intestinal fluid gushing out uncontrollably. He was fucked so hard by the vibrator that was thrusting in and out that his juices splashed everywhere. His eyes rolled back and he didn't even know when his tongue came out. He looked like he was about to faint.

At this moment, Tobirama was completely trapped in the tide of desire. His vision was filled with white light, and the sounds he heard were strangely distorted as if separated by a layer of water film. This punishment was indeed enough to make people feel afraid, but he did not have any extra thoughts to think about this at the moment. He could only scream loudly and beg for mercy out of control - it felt like he was screaming, but in fact he could only occasionally let out weak and broken moans.

Tobirama couldn't be sure if he had really fainted for a few seconds. He had completely lost the concept of time. On that horrible torture device, every second seemed like an eternity, until a certain moment, when his anus, which had been numbed by the penetration, was suddenly sprayed with a strong and warm stream of water.

The sensitive points that had been ravaged to the point of being miserably miserable could still be squeezed out of such intense pleasure. The scream finally broke through his throat. Tobirama's whole body was tense, and large streams of water flowed out without interruption. He didn't even realize that he had ejaculated, let alone what he had ejaculated. His lower body was forced to spasm and move, and the ejaculated liquid and the large amount of clear liquid squeezed out of the anus flowed together in a mess, wetting the entire horse's back. Even his consciousness seemed to be ejaculated together, creating a complete vacuum and complete blankness in his brain.

In the vast emptiness, only that cold voice flickered slightly.
[The second round of experiments begins]

When Tobirama regained consciousness, the first thing he felt was a kind of relief, like giving up.

In a short period of time, he could not figure out what he had given up. The memory of being punished just now was too vivid, bringing with it an intense fear that followed him like a shadow. During this period of time when he lost consciousness, it seemed that his brain and emotions, driven by this fear, were running continuously in a state of disarray, until he finally came to a conclusion.

That conclusion could not emerge clearly while the four-person sex was still going on like a storm, but Tobirama was surprised to find that he seemed to have somehow figured out the trick of how to identify Hashirama's true form.

This instinctive trick doesn't seem to be very trustworthy, but with no other choice, Tobirama decided to take a gamble.

His brother had always had bad luck in gambling, but this time, he was the one making the bet.

Hashirama's voice echoed in his memory: before today's experiment began, he said with a smile:
"I think I can always trust you, Tobirama."

I think I can always believe in you.
In the darkness, Tobirama felt the throbbing hidden under the surging tide of desire, and that subtle emotion guided him like a beacon.

Tobirama held a pair of warm hands, and those hands held him back.

The blood and bond, trust and time between us will last forever under any circumstances, so our fate is destined to be forever intertwined, protecting each other, like a shade tree and a nourishing spring.
Brother, please always give me guidance in what I am going to do, just like now.

The darkness in front of Tobirama's eyes was suddenly removed. He was blinded by the light and could not open his eyes for a while. He only had time to see two blurry black shadows disappear. The person he was holding, in a hugging posture, bent down and kissed him as the prompt sound representing the success of the experiment sounded.

Chapter 

18.
The seventh night passed peacefully.

The room suddenly didn't seem so scary anymore, especially as they kept their fingers linked.

The next morning, they were even awakened by the smell of breakfast.

It was a wonderful feeling, Tobirama thought. Ever since he was trapped in this room, this kind of awareness of "beauty" rarely appeared in his nerves.

But now, in the warmth of the darkness, before he even opened his eyes, he could smell the soft and fragrant ramen soup, the burnt aroma of the golden edges of the fried eggs, and the fresh fish and fruit.

Tobirama opened his eyes and saw that Hashirama, who was hugging him, woke up at the same time.

"Brother."
Tobirama called softly, and they hugged each other, their limbs intertwined so naturally, it was a wonderful feeling.
After this night's sleep, the pressure and anxiety that burned on the nerves before, the feelings that were deliberately avoided and hidden, all disappeared like snow under the sun.

Hashirama seemed to be the same as before, he never had the complicated entanglements that his brother had.

But no one said much, and they finished their breakfast in a warm and pleasant atmosphere, and the TV started flashing at the right time.

[Day 8:
A. Ask experimenter B to smash every bone in experimenter A's body.
B. Ask experimenter A to use every tool provided in the room on experimenter B (Note: The use of all props must comply with standard specifications, instructions for use are attached)]

After the snow, a slightly depressing cloud floated in the clear sky.

Hashirama obviously hesitated, wavering between the desire to try and the desire not to anger his brother, and a faint ray of light leaped out of his fingers - he had recovered more abilities today than yesterday.

But he really couldn't be sure whether his chakra, which was as weak as a thin sapling, could withstand the inhumane destruction of the mission.

Tobirama successfully stopped his brother from speaking with just his eyes.

That looked fine.
The brothers' eyes fell on the "props" that appeared at the same time. They were all a little unfamiliar, but most of them were not difficult to guess their purpose.

Hashirama frowned disapprovingly.

Tobirama patted his shoulder: "As I said," he curled his lips, "If it's you, then it's fine, brother."

"......"

"Their power obviously depends on the user's ability to control them," Tobirama's voice was a little like a whisper, but when he got rid of that self-doubt, this tone was always more convincing to his powerful brother, "Of course you won't hurt me."

"I... of course I won't hurt you."
Hashirama said this subconsciously, but his brows were still furrowed. His eyes moved back and forth between the mission requirements and the pile of "props", and suddenly he spoke:

"We need a word."

"What?"

"Whenever you feel it's really unbearable, give me a signal so that I can stop at any time."

Tobirama looked at him.

Hashirama insisted, "It has to be this way, Tobirama. I have to know when I have to stop."

There is no such time.
Tobirama's eyes flickered over the description of Task A, emphasizing the concept once again: There is no such time.

But he nodded and agreed to this setting.

"When you, uh," Hashirama thought and threw out a word carefully, "when you call my name - don't force it, you must remember it."

It was a good idea, Tobirama had never called his brother by his name, and once he was on the verge of collapse, this would undoubtedly be the syllable that could bring back the last bit of sanity.

Tobirama seemed to be unable to help but smile, and was very obedient: "Okay, Anika."

He took the initiative to pick up the eye patch on top and even made a joke.

"These experiments always seem to have a special liking for taking away my eyesight."

What I didn't say was the second half of the sentence: It's not fair that you're the only one who can see me.
Maybe if it weren't for this, I would be able to figure it out faster.

19.
"Are you sure you're okay, Tobirama? We can take it easy, or..."

There was a rare hint of nervousness in Hashirama's voice, and his hand was even shaking slightly - the hand holding the whip.

This was different. Compared to the missions of the past few days that were more steeped in ambiguity, today he was really inflicting not-so-easy harm on Tobirama.

Hashirama seemed to understand a little bit about his brother's resistance to daily option A.

Just like the previous few days, Tobirama was still the one lying naked on the bed, but today he looked more vulnerable and at the mercy of others.

Just as shown in the instructions for using the props, Tobirama in front of Hashirama had his upper face covered by a blindfold. At the same time, his entire body was tightly bound in black leather, with his arms folded and tied behind his back. The restraint had a ring around his neck, and the lower part was connected to his constantly rising and falling chest. The tight leather sank into his flesh, making his already full chest muscles look even more exaggerated.

The forced protruding breast flesh was covered with swollen bright red, and the nipples were swollen into bright red fruits, as if they would bleed and break the skin at any time - this was caused by the sharp teeth that were deeply embedded in the flesh. The two nipple clamps dotted with silver gems were a pair of beautiful torture instruments, clamping the swollen and sensitive nipples into an exaggerated state, making them look like fully ripe fruits that would break and ooze juice at the slightest touch.

That's not all. A tiny needle tip protruded from the middle of the two clamps and poked tentatively in the center of the nipple. With every rise and fall of Tobirama's chest with a breath, the sharp needle penetrated deeper.

The end of the needle was connected to a thin silver chain, extending down along the flat abdomen covered with sweat, passing the trembling pubic bone, and connected to another set of torturous leather tools worn on the lower body.

The restraint device was also made of black leather. The wide belt firmly held the base of the erect penis and tightly bound the swollen balls. Another thin needle was cruelly inserted into the urethra from the top. The huge gemstone at the end made it look more like a beautiful commodity on full display. Tobirama's legs were spread wide at an incredible angle, forming an exaggerated "M" shape on both sides of the body. The thighs and calves were tightly bound by the belt, and a rubber stick was placed between the ankles to prevent them from closing.

Between the two round buttocks that were forced to open completely, a thick massager was tightly squeezed into the anus that was stretched to the limit. From the wildly swinging tail, it was not difficult to see how it was wantonly ravaging the soft intestinal wall of the prisoner. Liquid that was roughly stirred was constantly squeezed out, soaking the buttocks with a watery glow.

This was really a very strenuous posture, and Tobirama's entire body was trembling slightly. However, even this kind of trembling that seemed to show weakness was not allowed. Whenever the amplitude of the trembling became slightly larger, the entire set of sexual torture devices connected to his body would be linked together, bringing more acute pain and stimulation, and once again inflicting the flames of sexual abuse on his nerves that were about to collapse.

All of this was enough to make Hashirama feel distressed and angry, but according to the instructions of the mission, he even had to add more fuel to the fire.

——The short, shiny black whip in his hand had left seven or eight criss-crossing scars on Tobirama's chest. Thin threads of blood slowly seeped out from the whip marks, and every hint of red was so dazzling.

They underestimated today's task, which was more difficult than any before.

Hashirama stopped more than once to inquire about his brother's condition, but each time, Tobirama just shook his head slightly - this was partly due to the rapid loss of strength, and partly because if the amplitude of his movements was increased, it would bring about a series of terrible chain reactions.

New instructions popped up on the TV screen.

Hashirama just took a glance and was almost overwhelmed by the raging anger spreading in his chest.

"Produce pleasure to the subjects through whipping"? ?
What kind of absurd words are these? For a moment, Hashirama couldn't help but suspect that when this whole strange experiment lasted for the eighth day, this room would finally show its fangs and imprison them in pain forever.

Tobirama was still breathing heavily. He could not see anything. Only pain and surging sexual desire filled his entire senses.

But he sensed Hashirama's hesitation and pause.

"Brother..."

Hashirama immediately caught the faint call. He tried to suppress his anger and gently placed his hand on his brother's completely sweaty neck.

"Brother," Tobirama tried to concentrate his scattered mind. The warm touch against his skin conveyed a kind of firm strength. "I'm fine. Please, please continue..."

Hashirama's fingers tightened uncontrollably.

"I'm not sure, Tobirama," he said in a low voice, "This is just the beginning. I'm not sure if we should continue."

Tobirama managed to tilt his head, which made his face brush against Hashirama's palm at a fond angle.

"We, of course."

"Tobirama——"

"Because it's us, of course we can." Tobirama's slightly trembling voice still revealed a gentle insistence, "We have suffered much more serious injuries in battle."

But that was not me. Hashirama's throat felt like it was about to explode, but he didn't say anything - but this was not a fight, this was a completely unequal torture, inflicted by my own hands, which encompassed both physical and dignified torture.

Anything is better than this, a small part of his brain screamed angrily, and Hashirama thought that he would obviously prefer to have all the bones in his body broken.

And Tobirama seemed to know what he was thinking.

A faint stream of air flowed out from Tobirama's slightly parted lips: "Brother," he said through gritted teeth, "I'm sorry to trouble you."

No matter which option they choose between the two of them, the one who inflicts the harm will undoubtedly bear greater psychological pressure. Tobirama understands this very well, which makes him feel a little sorry for his brother.

But he also always trusted that Hashirama, as the stronger of the two, would get through it, every time.

Tobirama turned his head and gently touched his lips in his brother's palm.

Hashirama took a deep breath.
"Well, if you can't stand it, Tobirama, you can always call my name."

With a "pop" sound, the gradually familiar pain, accompanied by the sound of wind, once again fell between the trembling waist and abdomen.

I don't know if it was an illusion, but Tobirama endured it, and when a drop of cold sweat flowed into the gap of the blindfold, he actually seemed to feel a hint of secret pleasure.

This was the eighth day they were trapped here, and the sex, which started from shallow to deep but was always rough and painful, seemed to have brought about wonderful changes in his body.

Pain is more than just pain.

For ninjas, "pain" is almost a daily occurrence that they are used to enduring.
But at this moment, the whip felt dull but sharp. When it hit the skin, the pain was short-lived, followed by a continuous burning sensation. Something was about to burst out from under the thin skin, ready to burst the swollen and damaged flesh at any time.

Once he thought about the complete loss of control and pain that was all caused by Hashirama, that tiny subtle flame quickly burned up, licking the sensitive nerves with a sizzling sound, and turned into a numbing hot current that flowed to the tailbone.

Tobirama was shocked by his own lustful body.

But he had no control over his thoughts at all. He had no idea when the next whip would come or where it would land. The only thing he could feel every second was the dildo stirring madly in his anus. His swollen prostate was being rubbed wantonly, and the posture brought by the restraints made him completely open. Under the gaze of Hashirama who was holding the restraints, he could not hide even the slightest reaction of his body.

Tobirama couldn't help but think about what Hashirama would think of him, seeing his brother shamelessly aroused while being whipped, humiliated, and fucked with a vibrator.

This thought made him feel extremely ashamed, but - as it was mentioned every time, the fact that "it was Hashirama" would make the shame reaction of lust more intense, and would also prevent everything from involving an unbearable collapse.

Tobirama bit his lip, but moans filled with pleasure still began to leak out from between his teeth.

The space between Hashirama's eyebrows twitched slightly.

He didn't know from which whip it started, but his brother's whole body began to turn a delicious pink color. Outside the blindfold, the bright red facial lines looked like they were about to drip blood. When the tip of his whip dropped, Tobirama's waist and abdomen moved slightly imperceptibly, as if chasing the stimulation that was going away.

Hashirama looked at the demonstration of "instrument usage" on the TV screen, and then looked at Tobirama who seemed to have completely put himself in his hands.

"Bang!"

Tobirama shuddered violently as if convulsing.

The new whip landed between his legs.
The tender flesh at the base of his legs was extremely sensitive, and a tingling electric current would jump out when it was gently licked. When the whip came down, the tip of the whip swept across the perineum and the anus that had been stirred to a sticky state, and landed heavily on the base of his thighs that had been stretched apart. Tobirama almost saw a flash of white light in front of his eyes.

"Ahhhh!"

A short scream squeezed out of his throat, Tobirama's whole body was tightly imprisoned, completely helpless to endure this overload of sensory stimulation, his toes curled up tightly and he unconsciously tilted his neck back.

That brought about a series of chain reactions. The leather belt at the neck pulled and lifted up the breasts, allowing the thin needles in the nipple holes to penetrate deeper, and the sharp teeth of the nipple clamps sank even deeper into the flesh. Tobirama took a breath of cold air, but his instinctive dodging movement pulled the urethral rod at the front of the penis again. The thin stick was tightly stuffed in the urethra that was forced to stretch, and was pulled out a little bit, and then penetrated deeper with sufficient mucus lubrication. As his chest rose and fell with his breathing, the thing went in and out so cruelly, like pumping and manipulating the tight urethra.

"Uhhhh—"

The tense balance that had been hanging on a thin thread was broken, and Tobirama was defeated in an instant. He felt a stimulation he had never experienced before, like torture, as if he was being fucked directly into his exposed nerves.

Hashirama's throat moved, and he noticed that the picture on the TV changed, and a small check mark appeared behind the image of the "whip", indicating that it had been used.

What's next?

A huge red candle popped up on the screen - the real object also appeared next to Hashirama's hand at the same time. The candle had been lit, the flame was dancing lightly, and drops of candle wax were sliding down the candle.

Hashirama's mind went blank for a moment. He stared at the "Usage Demonstration" on the screen, convinced that today's mission was too excessive.

But Hashirama did not delay for long, they had already come to this point, and the longer he hesitated, the longer the torture Tobirama would have to endure.

"Tobirama," Hashirama licked his lips, unsure if his brother, drowning in sensory stimulation, could hear him, "this might hurt a little."

Tobirama was absent-minded for a moment, then nodded weakly.

An oversized, perfectly round ball-shaped yoke was stuffed into his mouth, which stretched his lips completely apart. The muffled moans that he had been holding back suddenly poured out, and his uncontrolled saliva kept dripping, which made Tobirama feel more and more that he had become a tool for people to vent their lust. Then, he felt another new, indescribable pain.

Compared to the heat caused by the broken skin, this time it was pure burning - it was a drop of sticky liquid with extremely high temperature. When it fell on the sensitive breast flesh, it hardly flowed, but stuck to a certain place, continuously emitting a temperature that was about to drive people crazy.

Tobirama's chin was trembling, and there was a slight whimpering sound in his moans.

It was at this moment that Hashirama's kiss came down. His cool lips kissed gently from the tip of the eyebrows, to the corners of the eyes covered by the blindfold, to the tip of the nose, to the stretched lips, as if intending to divert his brother's attention.

That had some effect, in terms of making the pain more bearable—but in another way, it made things worse.

Tobirama could not see how the red spots of candle wax covered his white chest, like a glaring bloodstain or a flower blooming in the snow. He only knew that the constant torturous heat was changing with the effects of the obscene tools all over his body, and he seemed to be in a sea of ​​fire of desire.

Tobirama felt as if he was about to melt in such high temperature that he could not feel his own bones.

At this time, Hashirama turned his brother, who was lying on his back, over and made him kneel on all fours with only his buttocks raised high.

More wax began to drip, landing on the perky buttocks and even on the stretched tender hole. Excessive red wax accumulated in the middle of the buttocks, slowly flowing through the perineum and climbing up the bound and hanging penis, forming an incredibly obscene scene.

Tobirama's consciousness had completely fallen into confusion, and he finally began to feel a panic controlled by the pain. If it weren't for his complete trust in his brother, the pain would undoubtedly have come more intensely and earlier.

Fortunately, Hashirama's caresses and kisses continued to fall on him, like a spring of hope floating in the fire of hell. Tobirama tried to concentrate all his energy on it and tried his best to ignore the experiment that was becoming more and more excessive.

He soon could no longer tell what was causing pain and what was bringing pleasure, and he didn't know how long it would take for the scalding wax to stop dripping, nor how intense the shame would be when the hard slaps on his buttocks followed.

It's my brother... It's Hashirama.

Tobirama had to keep turning these two concepts over and over, as if that would help his dire situation, and he tried not to think about how he looked naked and having his buttocks whipped, the collar applied forcefully to his neck, forcing him to look up, and the pull of sex toys all over his body exacerbated the illusion of being deprived of his dignity and completely objectified.

"Tobirama, Tobirama..." Hashirama's voice had never trembled so much, "Crawl forward."

He might be like a wild horse that has just been tamed. Tobirama was amused by this thought that suddenly popped up in the chaos. He obeyed the instructions almost instinctively, without thinking about anything. He did whatever his brother asked him to do.

But crawling was a bit too demanding for the body's current condition. Although it seemed that some of the restraints were untied, the limbs that had been stretched out for too long with difficulty still seemed to not exist.

A sharp electric current appeared that almost pierced through the body.

Tobirama's moan almost broke, and he couldn't tell whether it was a punishment for not completing the instructions or just part of the task. However, strong electric sparks hit his nipples, urethra, and sensitive points deep in his intestines at the same time. All his defenses were penetrated in an instant. It felt like a water ball filled with liquid was suddenly punctured, and unknown liquid began to flow out from every hole. Tobirama's consciousness fell into a complete blank, as if part of his soul had flowed out with the semen or something.

"Aaaaaaah... No, no... Ugh... Save me, Brother!"

Unclear sounds were squeezed out from the gaps in the gag. Tobirama cried and screamed like a child, not knowing what sound he was instinctively trying to make. He fainted for a moment, and then a second - or even less, he was quickly awakened by the pain like a punishment. In his confusion, he tried desperately to find the familiar temperature and touch, but all the tactile senses in his body were confused, and he had nowhere to hide from the impending collapse.

"Tobirama, I'm here, it's okay... shh ...

Hashirama hurriedly held his unconscious brother in his arms. He tried to remove the cruel torture instruments as gently as possible, but during the long period of sexual abuse, many of them were embedded too deeply and almost merged with Tobirama - the removal process was undoubtedly another torture. He kept caressing and kissing Tobirama, but these actions had little effect on the body that was twitching and spasming in pain.

The heartache that was stronger than all the broken bones in his body almost pierced Hashirama, and he was completely helpless - it was hard to believe that those cruel actions were inflicted on Tobirama bit by bit by him, and finally forced his brother to collapse. He took off Tobirama's blindfold as soon as possible, but could only see a pair of blank, tear-soaked eyes, with deep red pupils dilated and unable to reflect his shadow at all.

The leather belt that tightly bound the body left a series of swollen marks, but that was only the lightest injury. Tobirama's flexible and thin body was covered with broken whip marks, which were now swollen into purple streaks; the nipples that had swollen to twice their size were bleeding when the nipple clamps were removed, and the blood mixed with the solidified wax; the lower body, whose chastity belt had finally been removed, stood up unnaturally, and a mixture of semen and urine was sprayed out in a disorderly manner. The buttocks that had been ravaged by the pain were red and shiny, and the anus that could not close in the middle was weakly open, and the intestinal flesh was still forced to spasm, squirting out mucus mixed with blood - Tobirama's lower body looked a complete mess, and it was even more tragic when it was used in turn by three "people" yesterday.

Hashirama carefully avoided the scars - which was almost impossible. He held his brother in his arms, kneading his earlobes and soothing his breathing while kissing him. He thought he would rather have a kunai pierced through his heart.

But the vivid voice of Tobirama a few days ago appeared in his mind almost at the same time.
"Last time Uchiha Madara made that request, you didn't ask me, right?"

Senju Hashirama was still stunned at this moment.

As the older one among the brothers, it was almost natural for him to care and protect. He always stood from the perspective of a superior and "decided" to protect Tobirama, the Senju clan, or Konoha.

This was the first time that the First Hokage watched someone suffer harm, while he himself was a bystander or even an abuser, completely powerless to do anything.

It turns out that being the one who is decided to be protected is so painful.

Hashirama's hands were shaking, and he was struck by his former self's arrogance. Before he put Tobirama into the bathtub as gently as possible, he gently kissed his brother's ear.

"I'm sorry, Tobirama."

Hashirama felt his fingers being wrapped by some gentle force.

Tobirama used all his strength to hook Hashirama's fingers. He still had his eyes closed, but the fear of falling into the abyss had disappeared.

In the ever-sinking flood, they are always each other's only and eternal lifeline.

Chapter 11

20.
"...There must be some conspiracy here."

Hashirama stared at the TV screen that had been smashed countless times in his mind with deep hatred, unable to believe what he saw.

"Listen to me, Tobirama, this is like a blatant trap. Otherwise, let's choose A today. I'm sure my heart won't die from a small stab wound now, but if what happened yesterday happens again, it might explode from the pain."

Tobirama blinked slowly: "Oh..."

Tobirama said, "You are obviously the one between us who is more suited to using your brain and making schemes, that's right."

"......"

But that does look abnormal, and that's true.

The ninth day's experimental tasks flashed on the TV screen.

[Day 9:
A. Ask Subject B to insert a kunai into Subject A's heart;
B. Ask Subject A and Subject B to have consensual penetrative sexual intercourse.]

Tobirama leaned back and looked at the two lines of text, as if he was lost in thought.

The mission on the eighth day was the most difficult they had ever encountered. After the painful experiment, Tobirama didn't even wake up from his coma to enjoy dinner. He didn't wake up until this morning.

Before Tobirama woke up, Hashirama, who opened his eyes before dawn, fell into a long period of anxiety. The theme of his concern was: if today's task B is more excessive than yesterday's, how can he force Tobirama to agree that they choose A.

Most of Hashirama's chakra had been restored, and he was sure that it would not be easy to kill him in this room with only two days left.

But the mission didn't appear until Tobirama opened his eyes - it looked so gentle, like a romantic promise on Valentine's Day.

"I think this is a good thing," Tobirama said, "Don't you want to, brother?"

Hashirama was speechless.

Of course he wasn't... unwilling.

But the day before had left him with lingering fears, and he believed that Tobirama was the same. The painful sexual abuse had made Hashirama worried, and he was not sure if just one day of rest would be enough for his brother to recover, and whether similar behavior would bring back memories that neither of them wanted to face.

Until Tobirama's hand was placed on his.

For the first time in nine days, it was Tobirama who leaned forward first and pressed a kiss to the corner of Hashirama's straightened mouth.

"Yesterday wasn't actually that bad," Tobirama whispered, "The pain was okay, and more importantly, I knew it was you, and I knew you would never truly hurt me."

"I would certainly never hurt you."

"Well," Tobirama's voice became even quieter, "So you want to come? To be honest, I was thinking at that time, if it was my brother instead of that vibrator..."

Hashirama held the back of his neck and swallowed the second half of his sentence which made his brother's face turn redder and redder.

It was a real kiss led by Hashirama.
On this point, Tobirama did not lie, it really made him miss and somewhat obsessed, the oral shackles in the second half of yesterday deprived him of the comfort between lips and tongues, when he was pushed to the peak of pain and desire, God knows how much Tobirama longed for the real Hashirama.

As if to prove something, both of them kissed hard. Yesterday's experience seemed to have become some kind of fuel, causing their desire for each other to suddenly burn to an unbearable level.

Hashirama's tongue forcefully forced its way into his brother's mouth, and his hand reached in from the hem of his raised combat uniform, tracing the heaving chest - which had regained its smoothness and elasticity. He pinched the perky nipples with his thumb and index finger, teasing them gently back and forth. Tobirama thrust out his chest in response, feeling dizzy from the tight kiss.

He is really hopeless. Tobirama thought in confusion, just having his breasts played with made him want to whimper, the familiar tingling sensation spread from his chest downwards, he couldn't help but cross his legs, the penis in his pants began to rise, and even his anus became slightly wet.

Tobirama was somewhat lost in this gentle and sweet kiss. He felt the naturally secreted physiological fluid flowing slowly along the intestinal wall, seeping out of the buttocks little by little, and gradually making the entrance behind him wet and soft.

He wanted to be stripped of his clothes, his legs spread, and he couldn't wait for his brother to penetrate him so that they could become completely one.

Two days ago, Tobirama might have been frightened by his own shameless thoughts, but at this moment he just bent his knees and hooked his arms around his brother's waist as if inviting him.

Hashirama may have been frozen for a moment, and then, as expected, his movements suddenly became fierce.

Their clothes were quickly torn off, and Hashirama inserted himself between his brother's parted knees. His fingers reached behind Tobirama with ease, found the hidden entrance, and was surprised to find that it had automatically become wet and soft.

Tobirama was breathing heavily, his arms wrapped around Hashirama's neck. They grew up together and he was no stranger to his brother's body, but everything had changed now. The simplest touches seemed to carry magic, igniting a series of flames in his body.

Tobirama couldn't help but move a little closer to his brother, his knees suggestively clamped around his waist.

Hashirama glanced into his brother's eyes with some surprise, and this time, those red pupils did not avoid him.

The foreplay didn't take long, as just eight days of "training" was enough to transform Tobirama's body into a completely different form.

When Hashirama actually penetrated him, he still didn't stop kissing. They were like two travelers who had endured thirst for a long time, looking for the source of water of life between each other's lips and tongues, kissing each other hard to part. When Hashirama thrust forward, a comfortable and vague murmur was squeezed out of Tobirama's throat. His whole body trembled, and even his tongue softened, and he completely gave up the dominant position in his brother's attack.

Good...increase...

Tobirama felt a weightless numbness in his lower abdomen. He wanted to say something, but in the end he could only let out soft gasps, which turned into broken moans. He felt filled so full that he could even feel the thick cock prying him open little by little.

Hashima inserted it without leaving any gap, and the thick and long shaft of his penis entangled with the wet and hot flesh inch by inch. Tobirama's thighs were stretched to the maximum and held tightly, but it didn't hurt. His flexibility made this action easy.

At the same time, Hashirama let out a satisfied sigh. The hot inner walls tightly wrapped around the invading penis, like a place of extreme desire that tempted people to fall. His brother raised his head under him, as if he had lost his mind because of his penetration. His wet silver hair swept across his sweaty forehead, and his eyes were full of water.
Hashirama narrowed his eyes. This kind of Tobirama made him feel new... It was as if, revealing an indescribable charm.

It is hard to imagine the enemies who were pinned to the ground by the tactical master.

Hashirama moved his lips slightly to kiss Tobirama's eyes and the increasingly red wrinkles on his cheeks. At the same time, he increased the movement of his lower body, swinging his hips wide and wide to hit Tobirama's deep inside, making a slapping sound between his pubic bone and buttocks, which made it extremely clear that he was fucking his own brother.

But their bodies were so amazingly compatible that Hashirama didn't need to search hard to rub accurately to the position that excited Tobirama the most. The sticky intestinal fluid was constantly pushed out of the vagina with his movements, making a splashing sound. Tobirama's waist twisted in time with his brother's rhythm, and his vagina skillfully contracted and expanded, sucking his penis as it moved in and out.

I want to go a little harder and a little deeper. During the most intense sex, it seems as if they can completely become one.

Such thoughts filled Hashirama's mind. He changed his position, letting the limp Tobirama lie on his side, and lifted one of his long legs from behind, pinning it on his knees. He grabbed the thin waist with both hands, pulled out the thick meat pillar completely, and then fiercely plunged the whole thing into him -

This position could really allow him to fuck to a more terrifying depth. Hashirama used so much force that he almost stuffed his entire scrotum into that tiny hole. Tobirama let out a short, dying scream, and his forehead was instantly covered with a thin layer of sweat. He felt like he was about to be pierced through by the length and thickness that felt like a red-hot iron rod.

At this time, Hashirama bit Tobirama's neck, just like a beast fixing its own female during mating. He freed one hand, inserted his five fingers into the gaps between his brother's weak and spasming fingers, and held tightly, biting and kissing this man who seemed destined to belong to him, as if he wanted to leave his mark on him inside and out, and fucked into his body again and again, deeply penetrating the soft flesh at the deepest part.

Tobirama felt that his thinking was becoming a little dull, the excessive stimulation made him want to dodge, but the fixed position prevented him from even slightly closing his legs. He could only let the penis inserted in his body do whatever it wanted. He moaned intermittently amid the overlapping sounds of sticky water stains and slapping. The tender hole that had been trained to the extreme was wrapped in warm and slippery juice, squirming to please and suck, and trembling with satisfaction at the older man's rapid thrusting.

He was completely fucked, and his response was shy yet excited, and his whole body was fucked until it felt soft and numb.

"Haaa... Brother... Ugh, slow down a little—"

Saliva dripped from the tip of the tongue that stuck out of the mouth, and the ripe, soft flesh hole was swallowing the penis vigorously. Hashirama looked at his brother who was falling in pleasure with admiration, and like what he wanted to do most every day before, he licked the tears on his face and kissed his trembling eyelashes. However, his hot penis was still aimed at that point and whipped it with redoubled efforts, changing the angle and fucking repeatedly. The gurgling sound of the flesh thrusting mixed with the young man's uncontrollable sobs - it was hard to imagine that they missed each other for so many years, and he never knew that Tobirama would look like this.

The two brothers were entangled in each other almost madly and indulgently on the big bed where so many things had happened. No one paid any attention to the TV screen that had long displayed "Mission Accomplished". Hashirama felt that he had entered an incredible depth, where Tobirama could not even make a sound. The end of his soft intestines was panicking and wrapping around the sweet invader, while his tender and moist flesh walls were being pushed at will without any resistance. At the same time, they were hugging and kissing so hard, plundering the air in each other's mouths, as if they were really intertwined in this way, as if they were born to be like this.

It's hard to imagine that after so many years of being together, they have never done this.

On the ninth day of being imprisoned here by an unknown force, the two most outstanding brothers of the Senju family suddenly felt that this experience was not entirely a bad thing.

Chapter 12

21.
Compared with the previous days, the ninth day was so free and leisurely that it seemed like a reward. After completing the task quickly (to be fair, it was not fast), they could still spend a long time lying in bed, cuddling each other, almost wasting time and feeling the passage of time.

Of course, there is also the residual pleasure of perfect sex.

But there is still a dark cloud of pressure that lingers vaguely. Although no one mentions it, before the impending last day actually comes, it is like walking on ice, never knowing whether the next step will be to fall into cold death.

No one knows whether today's brief respite will be the light before dawn or the dinner before execution.

The sweet and warm feeling brought by the hot sex was like a bubble, which was popped little by little in silence.
But even if someone noticed the change in the atmosphere, no one really said it out loud.

After a brief thought, Tobirama brought up trivial topics about village construction. Usually, this was not the kind of small talk that Hashirama liked, but when necessary, he would always listen carefully and offer very constructive suggestions.

Hashirama came up with the idea, and Tobirama implemented it and turned it into reality. This was a mode of getting along that they were very familiar with.

Although such discussions had never taken place in bed with the naked bodies intertwined, no one felt it was inappropriate.

They were just as casually discussing mundane matters as they had done countless times in the study, under the tree, by the stream, or anywhere else, and nothing else happened.

Even they themselves find it difficult to explain the chaotic feelings in their hearts, but there is one thing that cannot be said at this moment, but is absolutely necessary to consider.

If only one person could leave from here tomorrow,
at least Konoha could continue to operate safely and smoothly. In other words, at least one person must leave - even if it's just one person, they must be able to realize the common dream they have been fighting for for a long time.

That cold anticipation caused Tobirama's little finger to tremble slightly, barely perceptible.

They talked for a long time, and in the end they had talked about all the details until there was nothing left to talk about. The faint sunlight outside the window had begun to shine through the clouds, and the room fell silent again. No one wanted to sleep, and the two brothers stared at the silent TV, silently waiting for it to light up again.

Hashirama once again inserted his five fingers into Tobirama's seemingly relaxed fingers.

This led to a long eye contact, and Hashirama's eyes actually wandered first, then he cleared his throat, as if he had a strong interest in Tobirama's fingers.

"My abilities have been fully restored," Hashirama said, looking at their intertwined fingers, "all restrictions have been lifted."

Tobirama stared at his brother, then said after a moment, "Mine is completely gone."

This didn't seem like a good sign. Hashirama's abilities had been recovering at a slow pace, and along with them came options A that were more lethal each time.

Tobirama began to feel anxious. He was always in a more passive state. Option B was so mild yesterday that it ignited a secret hope in people's hearts, but it also gave rise to many speculations as to whether it would get worse today.

The point is that a fully formed Hashirama would be even harder to convince.
The Sage Body does not mean that there is no possibility of death. Tobirama's heart beats, and he will never allow -

The clasped fingers tightened again.

As if Hashirama had made a difficult decision, his gaze turned back and, like he had done countless times before, he locked eyes with Tobirama honestly and directly.

"I will no longer make arbitrary decisions, Tobirama."

"......What?"

As the sun rose completely, Hashirama used his arms to push Tobirama, who was caught off guard, into his arms. They maintained this somewhat awkward hugging position. Hashirama gently pinched the back of his brother's neck and pressed his forehead against his.

Too close, our breaths intertwined.

"I apologized." There was a smile in Hashirama's voice, "Whatever it is, we will face it together."

Tobirama froze, silently but tightly hugged him back.

Then they turned together and looked at the television which began to flicker as usual.

[Day 10:
A. Ask experimenter B to make a 2cm long and 1cm deep cut on the inside of experimenter A's arm.]

......What?

The completely unexpected content made them both stunned. Tobirama immediately remembered that this was the first day's challenge - even when the power was completely blocked, it was not a damage that Hashirama could not withstand.

But how is that possible?

Even the sound of breathing in the room seemed to disappear. They stared at the large screen, waiting for the text to continue to appear.

[B. Ask experimenter B to say to experimenter A: I love you.]

"......"

Hashirama turned around suddenly, and his warm black eyes began to sparkle.

22.
Tobirama's face turned completely red in an instant.

"That... but that's so... I'm not--"

But his brother swallowed up the rest of the words with a kiss.

23.
Tobirama tried to reach the kunai that Hashirama had on his waist.

But his brother took it in his hand first with a smile, and dazzling chakra surged out, and the small piece of metal instantly melted away without a trace.

24.
The first Hokage's most beloved brother and best assistant glared at the first Hokage.

25.
"Okay, okay!" Tobirama pulled away from another kiss in annoyance, which made his neat and clean ANBU clothes wrinkled and messy, and his mouth wet and swollen - not that there hadn't been worse in the past ten days.

Hashirama's expression was like that of a frozen lucky cat, but a bully lucky cat with extremely high combat power. It was obviously unfair that Tobirama had no power to fight back because all his abilities were restricted. His hands were easily locked, leaving him no room to struggle.

"I......"

Tobirama opened his mouth and choked, and his brother took the opportunity to quickly say the same words he had said countless times before quickly kissing his open lips.

If he could, Tobirama wanted to roll his eyes. He opened his mouth again and felt an itchy feeling in his throat as if something had drilled into it.

Hashirama's inserted tongue certainly didn't help.

"All right......"

Tobirama also cleared his throat, his red eyes moved left and right, and finally, as if he had made the most important decision of his life, he slowly and bravely turned back to the front.

"Just." He looked into Hashirama's eyes, and the tense facial lines softened instinctively.

"I love you."

26.
Everything around them crumbled like a sand castle flooded by the tide, real sunshine poured down from the sky, real grass gave off a green fragrance, and they fell into such a long and passionate kiss, forgetting themselves that everything in the world had nothing to do with it.

27.
So it may take a long time before you realize that the place where the room vomited out seems a little familiar.

And where did the terrible rumor come from?
