(Y/n) POV

"So how does this help you take down Great Red?" I asked Ophis as the final amounted of rust and sea life had been removed from the Yamato "I plan to draw him out form the dimensional gap, and the best place to do that is here" and she pointed to a mountain "That place is deep inside angel territory" I said and she nodded "I know, that's why we'll need the ship, it'll defeat any opposition that tries to get in our way and it has enough firepower to be able to get us back out once we've succeeded, assuming it doesn't get destroyed in the crossfire" and Ophis showed me her ideas for the new additions for the rebuilt Yamato, firstly it would be made wider and longer to be able to hold all the other new additions such as bigger engines to make it faster, more armor, and way bigger guns, the humans had put 18.1 inch main guns on this ship but with the upgrades we plan to fit it'll be able to incorporate 27 inch main guns, and twice as many guns, any bigger and even more extensive modification would have to be made. she then showed me a blueprint of what it would look like, it can even fly since of the relative lack of oceans in the underworld, with only the one that was not even that big, just deep "One question" I said regarding it "How in hell is this thing going to even get close to heaven without everybody in there seeing it form miles away?" "That's why it can shoot them from even farther away" and I saw Ophis point to a massive metal tube that was laying on the floor "That's one of the gun barrels" and I could stand up strait in it "Your really going all out aren't you?" I said feeling the rifling of the cannon "Go big or go home" she said sitting on it "Has your servant reported in yet?" she asked me "No, he says that they are looking in the surrounding area on the sea floor" and she jumped down "Let me know if they find it" and before she left she turned to face me "You know, I may be considered to share some of the dimensional gap with the underworld, if your interested~" she said with a sly grin and her hand running up my leg "I'm not a lolicon" "Who said you had to be" and her body was engulfed in a white light. When it went away Ophis now had a much more...developed body, she stood to my height, her new body was much more curvy, and her bust was on par or even better than Akeno. Still had the little black X's though. "This better?" and I just face palmed and did't respond "I'll take that as a yes" and she walked off giving a bit of extra hip sway. I just rolled my eyes and I left the bay, it's been awhile since I last heard from Sona but I just got word that she would be arriving back today so i wanted to meet them. I got into my throne room and I found them or what was them, It was Sona, her queen, and only three others "Hello Sona" I said and she quickly bowed and her peerage followed suit "Lord Satan" and she resumed her normal posture "So, this is what you brought with you?" I said and she nodded "As you know I already have my queen Tsubaki who you already know, some of my pieces rejected the offer to come her though" "It is fine, they will follow suit soon enough" I said examining them "So, tell me their names, I wish to know my new additions" "Of course" and she gestured to a white haired girl with light blue eyes "This is Momo Hanakai, one of my bishops, the other didn't come with" and she bowed, next was a girl with light gray hair and bright amber yellow eyes "Bennia, a knight" "Ah, a grim reaper, very nice" I said complimenting her and she bowed "Thank you Lord Satan" and the final one was a girl with brown hair and light blue eyes "Ruruko, my pawn" and she bowed "Well, as you all know I am Lord Satan, what I say goes and any defiance will not be tolerated in the slightest, I hope you enjoy your stay, Aksis" I said calling him over "Yes my liege?" "Show our newest additions around the place and what they will be doing" "As you wish" and he lead them away. I started wandering down the halls and eventually I found Akeno, when she saw me her face turned a little pink "Evening Akeno" I said and she bowed "G-Good evening". I smirked seeing her fidget since I saw her yesterday watching me and Serafall together. I'm not mad, not at all "Akeno, come here" I said and she stood in front of me with her face turning a bit more pink "Turn around" I said and she slowly did "You know" and I held her thighs "You do fill this out quite nicely~" and I started running my hands up her sides. I left my armor and I leaned right up to her ear "So tell me, did you enjoy watching?" and her face turned bright red "I..ummm... I don't kn-know what your talking ab-bout" she stuttered as I got to her waist "You do, you watched me and Serafall have sex and even masterbated to us, you enjoyed it" I said right in her ear and I held her shoulders "L-L-Lord Sat-tan" she stuttered again while the blush only got worse "We wouldn't have minded if you wanted to join, right Serafall?" I asked out loud and she came around the corner wearing a black lace corset, black gloves and stockings to match "No, I wouldn't have" and Serafall went in front of Akeno and unzipped a bit of her suit exposing a bit of her chest "Damn, I'm jealous these are huge" Serafall said running her finger up and down Akeno's breast. Akeno was now blushing madly and was leaning back on me so I held her up. We continued to tease her until we thought she had enough "Sera, would you say that we've teased enough?" I said feeling Akeno's stomach "I agree, do you want the real thing or would you prefer to just keep touching yourself?" "Please, give it to me" she begged with her face still bright red "Very well"

A short time skip

I laid on my bed with no clothes on and my erection in plain view, both Serafall and Akeno payed on their stomachs with their faces close to it "So this is a real one" Akeno said starring at it "I'm gonna teach you oral sex, first start by licking it like this" and Serafall started licking up and down. Her smooth tongue felt amazing as usual and Akeno was a bit hesitant to join in. She started at the base and slowly licked up the shaft till the head and circled her tongue before going back down. "Next take the head into your mouth and suck and lick" and Serafall took the head into her mouth and started sucking and licking under the head. Akeno watched her with a blush "Once your comfortable with that take more in" and Serafall started going down until I was all the way in her mouth, I could feel her throats as she began bobbing her head up and down, as usual her blowjob is amazing. I didn't make any noise as I held Serafall head and made her move faster. She backed away and pushed Akeno forward "Just like that, don't be afraid, it's tasty" she said as Akeno was a bit hesitant. But she got over it and started sucking, she took it all into her mouth and I heard her gag for a few moments before bobbing her head. Serafall moved so her panties were by my face and I removed them exposing her wet pussy. Akeno started going faster until Serafall made her back up "Try adding your tits, their big and soft so they'll feel good" and Akeno wrapped my length with her soft boobs. She moved up and down while licking the tip, I could feel my end coming. I came in Akeno's mouth and he eyes went wide "You made him cum, good job" Serafall said and grabbed Akeno's face. She pressed her lips onto Akenos and they started making out, Akeno's eyes were wide as my cum went from her mouth into Serafall's. They separated and Serafall said "Now spread your legs" and she got off me and went behind Akeno. She gripped her thighs and spread her legs exposing Akenos dripping wet pussy "Now he's gonna lick you" and I went by her pussy. Akeno shivered with anticipation and I licked her inner thigh to tease her before going in. I licked her walls and played with her clit all of which made Akeno into a moaning mess. Serafall twisted and played with Akenos nipples and she started sucking on her left breast. Akeno let out pants and pleas for more. I stopped licking her and I moved up to her breast "As you wish" and I started sucking on her other nipple. I stuck two fingers into her pussy and I moved in and out of her. Akeno was screaming in pleasure. I could tell Akeno was on the brink of cumming but I pulled my fingers out and she whimpered in protest "Relax, you'll get to cum" I said and Serafall spread Akeno's legs more and she said "Are you ready for the real thing?" and Akeno nodded. I lined up with her entrance and I quickly thrust into her. Akeno let out a scream of pleasure as I started fucking her. The noises that came out of Akeno's mouth were constant pleas for me to do her harder, fast, and she even wanted me to spank her which I obliged. I flipped her over so she was on all fours and I smacked her butt. Her ass was bright red as I felt my end come closer "Akeno, he's gonna cum, out or in?" Serafall said as she masterbated and played with her own breast "Out, I don't wanna get pregnant" and I pulled out and I flipped her over and I finished on her face. Akeno licked some of it and was still a blushing mess with her eyes half shit as her legs shivered "My turn" Serafalll said pushing me over and sitting on my hips and lining herself up "Hey (Y/n), I wanna try something else tonight" she said and lined her anus up with my length "Anal?" I asked and she nodded "Yeah, someone I know said it felt good" and she went down as I penetrated her ass. Serafall moaned as I started thrusting up into her. It felt similar to her pussy but not as wet but even tighter. Serafall started playing with herself as I could also feel myself about to cum "Sera" I said and she didn't stop "Do it in me, I won't get pregnant this way" she said as I came in her. Serafall also came and I pulled out with some of my cum flowing out of her asshole. We all payed together and no one slept better than Akeno that night.
