For bettythedwarfqueen I hope you don't mind that I picked John as the character the reader falls in love with 😂 this is going to be so fun to write, I hope you all enjoy it!
Don't forget, when it's JohnxReader, you're Sherlock's little sister, same as in 'You Deserve Better.' 😉

That's what you're wearing in this oneshot. Feel free to check out my profile on Covet, that's my username on there since I made that look. 'AllHailTheZucchini'

Being the only younger sibling of Sherlock's (and the only one that didn't annoy him to death...we're all looking at you, Mycroft) definitely made you his favorite out of the two siblings he had. Sherlock loved you to no end, even though he was a sociopath. He always had you over at 221b, having chats about cases, poking fun at Mycroft, and you sneaking glances at your brother's flatmate, John Watson. Not that Sherlock was oblivious to this, even though you hadn't told him.

So there you were, sitting with Sherlock and John around the kitchen table, drinking tea and chatting.

"So, John," you addressed your crush, leaning back in your chair and putting your hands behind your head. "Has Sherlock taught you to deduce yet?"

John laughed. "No. No, no. I've caught on a bit, from being around him so much. But he hasn't actually..shown me how to deduce, no. Just enjoys showing off," John gave his flatmate the stink eye, causing you to giggle.

"Yeah, he does that a lot." You paused to take a sip of your piping hot tea, wincing a bit at the temperature. "Sherlock, why don't you teach us how to do deductions? Simple ones, y'know."

Sherlock perked up at the suggestion. "Sure, why not?" he smirked. "Okay, first off, don't be frustrated when you're not an expert at deducing right away. Doesn't happen. It'll take lots and lots of time to get it down." The consulting detective sat up in his chair and put his hands in the air by his head, as if he was about to slam them over his ears. "You must heighten your senses. Begin with one article. Be it clothing, jewelry, or a part of their body, focus on that one thing. Look at everything about it. If you don't pay attention, you might miss something crucial. Ordinary people like you: you see, but you do not observe."

"So you say," You said with a tolerating smile. "Constantly." John sniggered a bit. "So," you continued, "how do we deduce someone without staring at them like creepy stalkers?"

"It will take practice," Sherlock answered, sipping his tea. "I am able to deduce practically everything about anyone in seconds, it never looks unnatural."

You raised an overly-skeptical eyebrow at him. "In seconds you say? And it never looks unnatural?"

Sherlock shook his head. "Never. I saw everything about your day, sister mine, from the moment you walked in. For instance, I know you had had a good amount of sleep but very little rest last night, maybe because you had too much to eat too soon before bed..mmm probably because your thoughts were keeping you awake. You're still thinking about getting that puppy from the shelter. You'd like the cat, but you're shying away from that idea since you're allergic and you don't want to take the chance of it setting your allergies off. I know you had leftover pizza for breakfast—whilst in your pajamas—and that you rushed to get dressed so you could get here on time. Even so, you carefully chose your outfit, and assuming by the coordinating colors in clothing and makeup you chose, it was probably in an attempt to make an impression upon a certain someone. You've informed me that you have nothing else to do and nowhere else to go today besides my flat, which narrows down the field considerably. So either you are trying to get with the old beggar on the corner or John here. Obviously John, I mean, every time you visit you simply stare at him. Whenever he talks to you, your pupils dilate, blood rushes to your face, and I can guarantee your pulse picks up speed. Conclusion, the only reason you came to see me was to see John, because you. Like. Him." Sherlock sat back, satisfied.

You however, were in total shock. Your mouth was open in indingance, and you blinked repeatedly in an attempt to clear away the confusion. After a few moments of silence, and John looking at you in surprise (he didn't doubt for a second that everything your brother had just said was 100% accurate), you spoke. "I didn't come just for John, Sherlock."

Your sleuthing brother smirked. "But you did come for him."

Your cheeks rapidly grew redder by the second as you bit your lip, fighting the urge to punch your brother in the face. "...Yes."

John smiled to himself as he looked around, anywhere but towards you, knowing it would probably make you feel more uncomfortable than anything right now.

Suddenly, Sherlock's phone buzzed. He checked the text quickly, then smiled. "It's Lestrade," he addressed you, donning his blue scarf. "Says he's got paperwork for me to fill out from yesterday's case. I'll be back within the hour." He put on his long black coat, then looked to the both of you. "Many happy years," he teased, then walked out, leaving you both to blush and stammer out confessions of love.
