Oh God. Sherlock is kissing him. John is so surprised that he simply stands there doing nothing for a good three seconds. Sherlock pulls away, looking ashamed.
"I'm doing it wrong. I'm sorry. I thought..."
"Shut up" John grabs Sherlock's scarf and pulls him down into a second kiss. This time, both parties are active participants. John isn't sure who opens their mouth first but suddenly there are tongues and warmth and so much feeling that John gasps and pulls Sherlock even closer. Their first kiss is already so intense that neither knows what to do so they just fall onto the couch and continue making out like ridiculous teenagers.
In the back of his mind john thinks Oh. This is what I've been missing. And he almost weeps because he can't believe what an idiot he's been. Sherlock is always telling him so. How could he have missed this?
For several minutes they simply can't stop, their kisses becoming less heated and more rhythmic as they both realize that this could go on for some time and they both need oxygen. John finds himself laughing against Sherlock's lips.
"What?"
"I think" John chuckles again. "We were arguing about something."
"hmmm..."Sherlock almost purrs, nuzzling John's neck. "We should argue more often."
Suddenly John pulls away, glancing at Sherlock's puffy lips and even-messier-than-usual curls with a touch of pride.
"So, what exactly happened to you being 'married to your work' you git?"
Sherlock considered the question carefully. "well, first of all, at the time that conversation took place, not only had I just met you, but I was on the trail of a serial killer and in no position to get emotionally attached. Also, seeing as I had never been in any serious relationship, or really any relationship that was not purely physical-everyone experiments during university, so I learned then that girlfriends were really not my area, but I was...rather difficult to get along with even then.
"I had long ago come to terms with the idea of living the rest of my life in solitude. People began to assume that I was asexual and as an act of self-defense I saw no reason to correct them. Therefore I was woefully unprepared for the rush of...er, emotional confusion... I felt around you. By the time I deduced that you were attracted to me, I had realized-by way of similar experiments- that I was attracted to you as well.
"My god, Sherlock, you would manage to make the fact that you fancied me from the get-go sound like a lab report, wouldn't you?"
"Ha. Well, at least I wasn't in the cupboard for the three years during which I lived with the person I fancied."
"Closet, Sherlock, NOT cupboard."
"Oh."
They return to kissing.
Oh God that was so fluffy D: I swear there will be a plot to this but in the meantime try not to gag...
