Sherlock Imagines

Preference- Couples Halloween Costumes

Okay, I am going to continue my previous story preference thingies, but I wanted to do this. I'll have a few these in the lead up to my FAVORITE HOLIDAY!
I'm a Halloween-Hoe, I know.

Sherlock~
"C'mon Sherl! It's only for a couple of hours, then you can take it off!" You held up the beige suit jacket, the deep violet bow tie draped around the hanger. A fiery orange lock fell into your eyes yet again, and you quickly brushed it away to find Sherlock giving you a face that screamed, 'Really?'
"Y/n, why would I wear something so ridiculous? Not to mention that it gives the false idea that we are a 'couple', as John so indelicately puts it." And there's the shot to your heart. The great Sherlock Holmes either didn't care enough to deduce your little crush on him, or he knew and still just didn't care. It was heartbreaking, but it was your life. You let out a small scoff, simply to capture his attention. Fact is, he did care. E just honestly believed you didn't like him.
"Oh please, since when do you care what people think?" You placed your left hand on your hip, and let the arm holding the glorious costume fall a bit. His face scrunched up, trying to think of something to say back.
"Plus, I can't go alone. Amy Pond without the Doctor is like Cas without Dean! John without you, even! I need a Doctor, Sherlock, please?" You put on your biggest set of Puppy eyes, and Sherlock looked at you for a bit, before moving his gaze to the costume. He exhaled in defeat before standing up, and snatching it from you. He slunk to his room, and you did a small victory fist-pump. To be completely honest, you didn't really expect it to work. But he came out with the red converse you'd laid in his room for him, and the Sonic screwdriver in his pocket. You quickly fixed his hair, which despite all the curls looked pretty great, and stood back to admire the proud detective. A sudden squeal escaped your lips, and you lunged onto him, attacking him with a hug.
"You look amazing, Sherl! Thank you so much!" Still a little startled, he gingerly wrapped his arms around your figure, and for the first time since Moriarty returned; he smiled. It was a teensy-tiny smile, but it was completely genuine.
"We better get going... ALLONS-Y!" You leapt towards the door, and he shook his head and tucked his hands in his pockets, chuckling lightly as you held the door open for your tall friend. Getting to the party was rather boring, a short cab ride and there you were. Nothing too special. You knocked three times on the door, and John greeted you as it opened. His jaw physically hit the floor when he saw Sherlock standing beside you (even though he looked rather bored), dressed as the Doctor.
"Hello, John!" You sang as you shoved your way inside, Sherlock stopping next to the hobbit of a man.
"She actually convinced you to do it!" John commented rather amazed. Sherlock hummed as his eyes remained following you, attempting to not be obvious. John followed his gaze in confusion, and a small smile stretched across his lips as he found Sherlock was looking at you. Maybe he was being rather crude, but this was rich for John.
"Planning to take a ride in her 'Tardis', Doctor?" John nudged Sherlock's side, chuckling lightly. All of Sherlock's muscles seemed to freeze and compress at the same time. His face deciding this was the perfect time to be Molly's favorite colour- rose pink. Sherlock attempted to clear his throat, but the lump in it only grew. He swallowed hard, embarrassed for the first time he could truly remember.
"O-Of course not. That would imply I fancied her, John." Sherlock looked away, unable to look in the general vicinity without you catching his gaze. John rolled his eyes in an exaggerated sigh. Everyone- Lestrade, Mycroft, John, Mrs. Hudson, even Molly!- knew Sherlock secretly was head over heals for the charming, slightly childish, fandom-obsessed woman who lived in the flat below them, aka, Y/n L/n.
"Alright. I was only kidding, Sherlock." No he wasn't. He didn't want him to go as far as to sleep with you, duh, but he did wish his friend would own up to his emotions a bit and make a move-Any move. The night played on, and soon an ex of yours found himself bumping into you 'accidentally'.
"Oh! Hey Nathaniel!" You chirped, unaware of the detective sleuthing about. It was clear to him you really wished the bloke would back off- Did Nathaniel get the memo? Not a chance.
"Y/n! Hey, what's up?" After a LONG (and by long we mean two minutes of painfully horrific flirting) Someone tapped on Nathaniel's shoulder.
"Excuse me, but could I steal Ms. L/n from you? This'll only take a second." He literally shoved Nathaniel out of his way, and instead of the polite tone most would've adopted for the question, it was his usual 'get out of my way, twat' tone.
"Hey! I was trying to talk to her! You can't just do that!" Sherlock rolled his eyes, spinning on his heel in an exaggerated manner to face the not-quite-as tall, blond male.
"I believe I have every right to. She is wearing a matching costume to the one I am, what most people on this hideous holiday call a 'couples costume', it's only fair to reason she is my 'date' for the evening, yes?" Nathaniel was a little, well, shocked-embarrassed-hating-sickened-other words I shouldn't mention, to hear this. You were on cloud nine, yet somehow mortified. Despite all the emotions running in his head, the look he was giving clearly informed he didn't believe. Sherlock rolled his eyes, huffing out an annoyed breath.
"I suppose I'll have to prove it for you? Fine." Without warning; one of his arms snaked around your waist, pulling you to his side, and giving no time for you to register what he was doing, he pressed his lips to yours. It took only a bit to play along, this was an act Sherlock sometimes had you preform when it came to cases, so it came almost naturally. You simply began kissing back. First thing Sherlock said when he pulled away?
"See? My girlfriend." Before dragging you away with him to continue conversing with John.
