"Oh holy hell" John stopped dead in the doorway of the kitchen just in time to see Sherlock's face as he erupted inside Molly and John being the proclaimed heterosexual he was (though every time he touches himself, he imagines Sherlock), was embarrassed to find that Sherlock's expression and his moan had caused his body to react in a way he'd prefer no to.

"Problem John?" Sherlock asked as he pulled out and padded across to John still breathing heavily.

John shook his head but was having a little trouble keeping his gaze at eye level; Sherlock was dripping all over the floor. "You're...uhm...mopping the floor tonight and incinerating that table."

Sherlock grinned and pulled John into a tight embrace "I think" he whispered "that you may not mind the mess so much later..." John gulped and looked over at Molly who had pulled her clothes back on and was edging toward the door "don't leave on his account" Sherlock said, whirling to face her.

"Oh...no; it's fine" she assured him "I have to do some shopping anyway and...well...uhm; this was...fun?"

"Is that a statement, a fact or a question?"

"All three?"

"In that case" Sherlock beamed at her "it was my pleasure" and he all but pushed her out of the room.

"You do know that you're going to be paying for my dry cleaning expenses?" John told Sherlock as soon as Molly had left, gesturing at the white mess on his shirt "and anyway...what the hell was that?"

"Sex John, sex! I'm sure that you of all people know what sex is."

"Please don't tell me that you know when I've had sex..."

"And when you've been pleasuring yourself, yes" Sherlock grinned.

"So how then? Are my cheeks flushed? My hands warm or-"

"No; I hear you through the walls..."

John blushed "and the sex?"

"You can't look at me until you've showered which makes me think that whilst that woman was pleasing you...you were wishing that it was me. Now" Sherlock looked down at his soft member and brushed a finger down it and grimacing "I need a shower." And just like that he walked into his room and shut the door leaving John standing where he'd left him, semi hard, embarrassed and confused.

Sherlock had sent John to see Mycroft at the Diogenes club on a fool's errand; as it turned out Mycroft wasn't there at all so Sherlock had meant for him to walk in and...John growled and shook his head before deciding to change his clothes. Before he reached his room, however, Mrs Hudson appeared "oh, John" she smiled "I was wondering if you needed-oh" she'd seen the stain on his trousers. "I hope I wasn't interrupting anything, dear; I'd hate to be the one to interrupt you two especially when Sherlock is as sexually stunted as he is." She pouted, shook her head and left.

"God!" John sighed as he ripped off his trousers and went to dab at the stain.

It refused to shift and as he scrubbed at it, it seemed to spread and soon the white stain looked like John himself had had quite an embarrassing accident.

"Annoyed, yes...sexy...standing in his underpants yelling at my stain...sexy..." John whipped around to see Sherlock, dripping wet from his shower and completely naked. "You are very sexy, John." Shit. John tugged at his shirt to hide his growing arousal and wished that the floor would open up and swallow him whole. "Don't hide it, John; I'm not hiding mine..."

Of course he wasn't; Sherlock didn't care about revealing himself...he'd probably walk around buck naked all the time if he could get away with it without being issued with indecent exposure. "I uhm...yeah."

"I'm quite aroused" Sherlock unnecessarily stated.

John gawked at him "you...you are a machine" he said feeling absolutely flabbergasted "you don't have sex until now and then you can't get enough of it!"

"Who said that I haven't had sex until now?"

"Your erection!" John bellowed.

"Well I do feel like a teenager" Sherlock giggled...giggled! "John..."

"What?" He snapped

"I think I need a Doctor..."

John had been trying so hard not to melt as Sherlock's voice alone but now...now "oh holy fuck, Sherlock."

"Now, now Watson; no need to..." but John had lurched forward and smashed his mouth against Sherlock's, kissing him like he'd those teenagers do on the street corners. He just couldn't get enough of Sherlock's tongue and moaned as his soon to be lover thrust against him. "You seem to be over dressed for this particular occasion" Sherlock muttered as he ran his hands down John's chest and ripped open the shirt; ignoring the buttons as they flew across the room.

In normal circumstances, this would have thoroughly pissed John off but not so much right now. He shimmied out of his pants and kicked them to one side leaving them both utterly naked. His hands ran down Sherlock's back, dragging his fingernails over the skin and then gripped the young, fine arse tightly, massaging the muscle beneath it.

Sherlock was gorgeous, absolutely stunning. His skin was almost pure white and he was toned as though he worked out at the gym everyday...perhaps he did; John felt a little uncomfortable as he thought about his own body. He wasn't fat but he wasn't as slim and toned as Sherlock but Sherlock seemed to enjoying himself as his hands felt every inch of John's body.

After what seemed like hours, Sherlock broke the kiss and stared down at John. Both pairs of lips were swollen and red and both men were panting. They looked down in sync but it was Sherlock who reached down and clasped both of their members in his large, sexy hand and began to pump them both at the same time. John moaned and buried his face in Sherlock's shoulder, kissing, sucking and nipping the skin under his lips. Sherlock made a noise which made John look up; eyes foggy with arousal and desire. Their lips met again as Sherlock removed his hand and began to buck against Johns hips.

"Sher-" John gasped "Sherlock!"

"Yes John?" The sound of his name cause John to moan louder and twist his fingers into his detectives gorgeous dark curls.

"I need...I need you; right now."

"Like this?" Sherlock dropped to his knees and took the head of John's cock into his mouth and sucked gently.

"Holy mother of- sweet Jesus of suburbia!" He tried hard not to buck into Sherlock but failed and almost choked him. Sherlock breathed through his nose and relaxed his throat so that he could take John deeper. "Sherlock; you don't have to do that I don't- oooh god!" Sherlock chuckled around John's cock which made John thrust deeper and pull his hair tighter "Sherlock, stop it...now, Sherlock I'm gonna- OH Christ in a bucket!"

Sherlock sucked hard through John's orgasm and swallowed every bit of white, hot spunk before releasing his Lover and standing up. John has collapsed onto the sofa panting and Sherlock watched John's cock soften before taking his own in hand and pumping hard.

"No" John muttered and sat up, clasped Sherlock by the hips and started to return to favour. He knew that he wasn't as good as Sherlock though he didn't know how Sherlock had gotten so good...maybe he'd practiced on a cucumber or something but he tried to make his mouth and tongue recreate everything Sherlock had done to him.

Sherlock moaned audibly which urged John on and Sherlock couldn't quite control himself as he started to buck uncontrollably into Johns mouth which, being thicker and longer that the man in front, made John gag and splutter as Sherlock came hard and collapsed on top of John in a sweaty, exhausted heap.

"Are you done now?" John panted "did that satisfy your teenage urges?"

"It did" Sherlock replied "for now..."
