Sherlock smirks a little as he looks over at John, waiting until the doctor gets closer to the bed before he slowly starts to sit up, getting onto his knees on the bed. "Am I?" he asks, having an impish glint to his eye as he looks at the other man innocently. When he gets close enough, Sherlock wraps his long arms around John's waist, caressing his skin as the detective kisses him, using everything he's learned so far as to what John likes and what he responds to best. All of which he has paid careful attention to and filed away in the 'John' room of his mind palace. Minutes pass like this before Sherlock finally breaks away, slowly kissing along the doctor's jaw and then down his neck slowly.

This was not what John expected when he came over closer to the bed, but he doesn't mind the kisses, his hand sliding into the already mussed curls, his other hand curling around to draw little circles on Sherlock's lower back near the waist of his pants, stroking the skin softly. But when the younger man starts kissing down his jaw, he takes a deep breath, tilting his head up a little bit, contrary to the words that come out of his mouth. "Sherlock.. I thought we agreed, nothing sexual here, and definitely not yet..." he says quietly, though he makes no effort to stop his actions since it's been quite a while since he's felt... physically desirable this way. Most of the time it's him pursuing the women, him seducing them, they don't usually give him a whole lot of attention back, besides kissing and such. They don't take the time to learn what he likes, how he likes things. But Sherlock being the brilliant man that he is, applies his process the same to this as he might to solving his case.

"We agreed not to shag. I don't intend to take this much farther." Sherlock reassures in between kisses, long-fingered hands exploring the well-muscled back of his flatmate. "I finally get the chance to touch you, John. Please let me." He says in a softer tone, sitting back a little away from John to look at him. He feels very exposed and vulnerable right now, not trying to hide it from John, his sharp eyes looking over the other man's face and briefly down over the rest of him, looking for any signs that he's not doing the right thing, that this might be a Bit Not Good.

John isn't quite sure what shocks him more, the fact that Sherlock actually said 'please', or the vulnerable, uncertain expression on his face. He doesn't release Sherlock, so it's easy to pull him back, pulling his hand from those curls to cup his cheek and brush this thumb over those sharp cheekbones. "Oh, Sherlock.." He whispers quietly, leaning down just slightly to kiss him again lingeringly. Tenderly breaking it, he smiles a little. "Alright.. It's not as if I could ever say no to you, anyway." he says with amusement, sliding his hand back into the curls to card through them slowly.

Sherlock looks more than pleased, and perhaps a little predatory as he quickly moves back close to John, nipping at his ear and breathing a soft. "Thank you.." In his ear before he moves his attentions back to his neck, kissing, nipping and sucking on it as his hands caress over his skin. He's done with one side and kisses along his collarbone and shoulder, before he licks a stripe up the front of John's neck, nipping at his upturned chin before he moves to the other side, wondering if it's as sensitive. If the sighs, and soft groans are anything to go by, he's doing an excellent job. And the effect is rather obvious in the tightening of John's pajama's as well, which further pleases Sherlock.

"Blimey, Sherlock.. You're good at everything, aren't you?" John asks, breathing a little heavier as he submits himself to Sherlock's explorations, tightening his hand on the back of Sherlock's neck with a small gasp when the detective licks up his throat. After the nip, he lets out a small groan, hand splaying open on Sherlock's lower back to pull him a little closer.

A deep, dark chuckle comes from Sherlock as he hides his face slightly against John's skin. "I am a genius." He points out, placing a few more soft kisses. "You always have a smell of gun oil or gunpowder on you, did you know that?" He breaths, lips against John's ear.

"Cheeky." John says playfully, then he merely hums softly, knowing he should have guessed that Sherlock's nose would be sensitive enough to pick up things like that.

A few more sharp nips are given to John, and Sherlock notices the same reaction as when he placed soft bites on John's chest as before. A mixture of pain and pleasure, though John clearly enjoys it if the little, barely-contained thrust of his hips is any indication. A possessive part of the detective rears its head as he looks at the blank expanse of his doctor's neck and shoulder, and before he can think too much about it, he tightens his hold on John so he can't escape, before he bites down hard on John's skin, right at the junction between neck and shoulder, a place that will be easily hidden under John's normal shirts. His bite, combined with him sucking softly as well at the same time, is guaranteed to leave a rather sensitive mark by tomorrow.

"Sherlock!" John nearly shouts in surprise, and contrary to what his brain is telling him, his hand tightens in Sherlock's hair, hips thrusting forward as he pulls the younger man's head closer to him, and throws his head back with a small gasp, breathing heavily as he feels Sherlock release him. "Fuck." he says in shock afterwards, blinking a few times and feeling rather dazed.

Deciding to let John recover for a few moments, Sherlock gently starts to lick over the bruised spot after he releases John, soothing it softly with his tongue and placing a soft kiss on his skin. "My, my, John.. you are very responsive.." he says with a small smirk, before he presses close to gives him a soft kiss, then realizing something is different, he sits back on his heels, glancing down at John's trousers to arch an eyebrow a little. "Mmmm.. /very/ responsive.." he says in a slightly deeper tone, eyes raking up John's form to look into his eyes, a small, satisfied and smug look on his face.

Confused, and still a little out of it, John slowly looks down as well, eyes widening as he realizes just what happened and why his head feels so fuzzy. His mouth opens and closes in shock as he realizes that Sherlock had him worked up enough, and that spot is apparently enough of an erogenous zone for him that he orgasmed from the bite. No words come out of his mouth so he closes it, a blush creeping up over his cheeks. Finally, he clears his throat as he looks at the detective. "Er. Right. Well. Apparently I should go clean up." He finally says, awkwardly turning to retrieve another set of clothes and walk slowly to the bathroom to get cleaned up and changed.

Giving him a few moments to himself, Sherlock gets up after a few minutes of water running, figuring that John should be cleaned up. Displaying his usual lack of respect for privacy, he walks over to the bathroom door and opens it, finding John leaning toward the mirror to examine the blooming bruise. "Don't worry, it will be easily hidden by your ridiculous jumpers." he says playfully as he leans against the doorway slowly, meeting the older man's eyes in the mirror. "I'll have to keep that spot in mind, however." he practically purrs as he pushes away from the wall and moves up behind John, slipping his arms around his waist.

"I still can't believe I... that.. has never happened to me before." John admits, blushing again as he glances at Sherlock in the mirror, admiring the image of them together for a few moments and putting his hand over one of Sherlock's on his chest. "From a medical standpoint, I'm rather surprised such a thing is possible. At least for a man my age." he says with a self-deprecating chuckle.

"You're not that old, John. You're in the prime of your life." Sherlock says firmly, arms tightening as his mood swings from smugly affectionate to slightly concerned, statistics going through his mind combining with things that he knows about John and the doctor's physical health. His mind has too much information though and goes down too many roads. He can feel his heart pounding in anxiety as he thinks about something happening to John or losing him this soon, breathing coming quicker as he stares at John's reflection in the mirror.

Concerned as John notices the change in his flatmate's demeanor, he turns around quickly to look at him. "Sherlock? Sherlock, are you ok?" He asks, putting his hands on either side of the detective's face. Finally figuring out that he's going into a panic attack, he pulls Sherlock out into the bedroom, sitting him down. "It's alright, Sherlock. I'm here. It's ok." he says as he sits behind Sherlock, putting his legs on either side of him, arms around his chest. "Take deep breaths, Sherlock.. calm down." he says, taking deep breaths himself, letting Sherlock feel it. It worries him a lot that anything could cause this reaction, so when he figures out what must have happened, he tightens his arms a little, pulling Sherlock back to lean against him. "I'm right here, Sherlock. I'm not going anywhere. I'm a doctor. I look after myself. I'm healthy. Running after you makes sure I stay in good shape, you bloody idiot." he says playfully, kissing the side of his head gently.

Sherlock closes his eyes, matching John's breaths and taking slow, deep breath as he forces himself to calm down, "I apologize, John." he says quietly after he's calmed down, tilting his head back against John's good shoulder, taking a few deep breaths. "It has been a long day, as you know I'm not usually this emotionally unstable." he says quietly, closing his eyes as he relaxes into John. "Maybe we should go to bed. Despite the extra sleep I got this afternoon, I'm finding myself quite drained.

A small chuckle comes from John, reverberating through the man in his arms, before he turns to kiss his temple softly, then drops his head to kiss his detective's shoulder. "Come on, then. Get yourself up on the bed." he says before he slips out from behind him, blowing out the candles, giving his eyes a moment to adjust before he turns and heads back to the bed, climbing onto it.

"You can't sleep on that side. You have to sleep on the other." Sherlock says in a firm tone, almost petulant from where he sits in the middle of the bed. "We can't cuddle properly without you hurting your shoulder, if you're on that side." he scolds, waiting until John, chuckling, changes places. Then, Sherlock slips under the covers and makes sure to set the alarm before he slips over to cuddle up to John, wrapping arms and legs around John until they get comfortable.

"Goodnight, Sherlock." John says quietly, knowing he might have some trouble getting to sleep with how busy the day has been, fingers stroking Sherlock's back lazily to comfort both of them.

Sherlock stretches in a catlike manner for a moment before he returns to being curled up around John, nodding a little and rubbing his cheek against John's chest, already half asleep before he replies.

"Goodnight, my John."
