A/N; Yeah, I don't really know what this is. I was in the mood to write some slutty John and some Jim/John/Seb and somehow it became this. I am working on my other stories, I just can't concentrate on anything the moment. So have this instead.

Sherlock Holmes liked John Watson from the moment he saw him, which was a strange phenomenon for him. He didn't generally like people and never at first sight. It had been in the computer lab at St. Bart's. Sherlock was looking at some crime scene photos sent to him by Gregson, when John walked behind him, did a double take and then came to stand behind him. Sherlock was bit uneasy with the close proximity of another person and the strange feeling of John's breath on his cheek.

"For a second I thought you were looking at some really weird porn." John confessed, putting his school books down on the table next to Sherlock's computer. Sherlock glanced over and noticed a very large medical textbook on top and then looked up at its owner. John had a boyish face, dirty blond hair and very blue eyes. He was attractive in an easy-going sort way and his hand was resting easily on the back of Sherlock's chair as he leaned over him to peer at the screen. It was all strangely casual for someone Sherlock had just met. People he'd known his whole life didn't talk to him with such familiarity.

Sherlock saw how someone might make such a mistake. The photos were of a naked woman although the bruises and stab wounds were hardly alluring. "No stab wound to any major arteries." John said looking over the picture. "Whoever did this wanted her to suffer, make sure she bled out instead of making it quick."

"Yes." Sherlock nodded, impressed by the insight and yet confused by this boy's behavior. In his experience, this was not the norm. People often shied away from this sort of thing. But then this boy was clearly a medical student, accustomed to seeing gruesome details of human anatomy.

"You don't go to school here." John said turning his head to look at Sherlock. Their faces were oddly close together and Sherlock found it difficult to breathe. It had been a clear statement of fact, not a question but Sherlock answered anyway.

"No, I don't." Sherlock replied, pushing his chair back to get some distance between him and this new person. "But Bart's morgue is much better stocked than anywhere else I can find and aren't you going to ask me about the photographs?"

"What about them?" The boy shrugged.

"Aren't you going to ask why I'm looking at them? Ask me if I'm the one who killed her?" Sherlock asked, bewildered by this boy's nonchalance. Most people would have been deeply disturbed.

"Nah." John shook his head. "I see weirder stuff from my flatmates. Also, if you were the killer you'd hardly be looking at the photos of your crime in a public place. You don't seem that stupid." John gave him a friendly little wink.

"Sherlock Holmes." He said, extending his hand in greeting.

"John Watson." The boy replied, shaking it, giving a friendly smile as he did so. "Pleasure."

"Pleasure's all mine." Sherlock responded sincerely.

The second time Sherlock met John, it was at Bart's again, this time in one of the science labs. Sherlock was running an experiment, focused on looking under his microscope when the door burst open. Sherlock was frozen like a deer in headlights, stunned and unable to move. It took him a moment to recognize John who was busy sucking the face off some girl. He had his hand up her shirt while she giggled incessantly.

Sherlock had been hoping to see John again ever since that first strange meeting. He'd been finding more and more excuses to hang around Bart's in the off chance that he might run into John again. He had never expected to see him again under such circumstances. A part of him was just a bit disappointed to see John with someone else.

The two seemed to finally realize there was someone else in the room and stopped what they were doing. John turned, his lips red and smeared with lip gloss, to lock eyes with Sherlock. From the way John was looking at him, Sherlock felt as though he were the one under a microscope and he shifted uneasily in his seat.

"Hey, I know you." John said, wiping his mouth with the back of his hands. "Sherlock, right?"

"Yes, hello again John. You remember my name?"

"Well it's a strange one, innit?" John said, making his way over, any interest in his companion seemed to be abandoned. The girl glared at him but Sherlock noticed she wasn't leaving. John was now standing strangely close, which seemed to be common for him. Sherlock kept very still as John looked him over. He felt like he was being examined, thoroughly. John gave him a lopsided grin that made Sherlock's stomach flutter and blood rushed to his cheeks as he blushed with embarrassment of being so closely studied. He had never been on the receiving end of such attention before, usually being the one to fix people with his penetrating gaze. Mycroft had warned him that most people found such attention unnerving but with John it wasn't. In fact Sherlock relished in the attention John was giving him.

"Besides," John said, leaning in ever so slightly. "I never forget a pretty face."

Sherlock's blush deepened and he opened his mouth to say something when the girl cleared her throat, interrupting them. John turned towards her, his eyes widening as if until that moment he had forgotten she was there. He gave her an apologetic smile before turning back to Sherlock. "Sorry mate, this room's usually empty around this time of day. We'll just find some place else. Sorry to bother you."

"It's no bother at all." Sherlock said quietly. He wasn't sure John had heard him until his mouth quirked up slightly in the corner as if he was smiling secretly, just for Sherlock.

"See you around." John said cheerfully as he walked back to his date and slipped his arm easily around her waist, tugging her to him. Sherlock watched them leave together, a strange pang in the pit of his stomach. He focused back on his experiment, only to find that it had spoiled while he'd been distracted. With a heavy sigh, he began all over again.

The fifth time they meet, it is at the coffee shop down the block from Bart's. Their other meetings had been quick and wholly unmemorable but Sherlock remembered them all the same. John was there with a date, a man this time, and Sherlock wondered just how often and how many different people John went on dates with. It seemed that he was always with someone, their first meeting in the computer lab being a rare exception.

"Sherlock!" John called out to his, waving him over. Sherlock debated with himself for a moment and then begrudgingly made his way over to the table. John beamed at him and grabbed an empty chair from a nearby table, gesturing at Sherlock to sit down.

"Seb, Sherlock, Sherlock, this is one of my flatmates, Sebastian." John said introducing them, the wide smile never leaving his face. Sherlock relaxed a little when he learned that this was not a date and simply just John out for coffee with his friend. "I'll get you a coffee, what do you want?"

"Uh, black, two sugars please." Sherlock said quickly as John went up to buy him a drink.

"So you're Sherlock?" Sebastian asked, looking Sherlock over. "John's mentioned you a few times."

"Has he?" Sherlock asked, ducking his head to hide the large smile threatening to overtake it.

"Yeah, I think he's a bit smitten. Then again, it doesn't take much for our Johnny." Seb said, bringing his coffee to his lips and taking a long sip. "Has he shagged you yet?"

Sherlock sputtered, taken aback. "No, no, of course not." He said trying to recover quickly.

"Oh." Seb said, contemplating it as he took another sip. "Well he'll probably get to that pretty soon then."

Sherlock gaped at the man but snapped his mouth closed as John rejoined them at the table. He put the cup down in front of Sherlock, his hand brushing against Sherlock's, just a hint of fingertips against the back of his hands in a subtle caress.

"Well, I'd better be off. I'm meeting Jim and then we have class. See you at home?" Sebastian asked John.

"Yeah." John nodded.

"Nice meeting you." Seb said, eyes flickering to Sherlock before he downed the last of his coffee and tossed the empty cup into the bin.

"You too." Sherlock said, shifting awkwardly in his seat.

"Bye John." Sebastian said to his flatmate before leaving them alone. Sherlock racked his mind for something to say when John placed his arm over the back of Sherlock's chair, moving a bit closer so their bodies were slightly pressed together at the side.

"Your friend is very…eh…direct." Sherlock said struggling to find the right word.

"He is." John agreed, using his unoccupied hand to drink his coffee. "It's one of his many charms. Seb isn't big on bullshit, finds it a waste of time. It's actually a bit refreshing."

"How long have you two been flatmates?" Sherlock asked, lifting his cup to his lips to blow on the hot liquid.

"Oh man, it must be about two and a half years now." John said absentmindedly scratching his eyebrow with his thumbnail.

"Sebastian, he, uh, painted you as rather promiscuous." Sherlock confided.

John shrugged. "I am rather promiscuous."

"Oh." Sherlock said dumbly, taking a moment for that to sink in.

John leaned forward so his lips were close to Sherlock's ear, his breath hot against it. "Is it a problem?"

"I – uh – I…." Sherlock stammered, caught off-guard by John's close proximity.

"Because I'd very much like to take you out." John said, nipping at Sherlock's ear.

"Yes!" Sherlock practically shouted right away. He cleared his throat and ignored the redness of his cheeks. "Yes, I'd like that."

"Good." John smiled, placing his hand on Sherlock's thigh and giving it a light squeeze. "First things first, I think you should give me your number."

"Honey, I'm home." John called out as he dropped his keys into the dish by the door. He walked through the flat, looking to see if anyone was around.

"In here." Jim called from the kitchen.

"Hi." John said walking over and giving Jim a quick kiss as a greeting.

Jim grabbed him by the hair and kissed him deeper, licking his way into John's mouth. John pulled back and then nipped at Jim's bottom lip. "You had pancakes?" John asked, pouting slightly.

"You weren't here." Jim shrugged, starting on the dishes.

"Why are you so mean to me?" John asked, wrapping his arms around Jim's waist and kissing the nape of his neck.

Jim leaned into him, a breathy moan escaping his lips. "Alright, fine. I put the leftover batter in the fridge. I'll make you some."

"Thank you." John said pulling away.

"Tease." Jim said flicking bubbles and water at John's retreating form. John jumped out of the way and grinned.

"You don't get any more than that until I get pancakes." John said over his shoulder.

"Then where are you going?" Jim called as John started to strip as he made his way down the hallway.

"Shower." John called back as he stepped out of his trousers.

He walked back into the kitchen twenty minutes later in his dressing gown, rubbing his hair dry with a towel. He noticed his clothes that he had strewn about the flat had all been picked up. He smiled, knowing Jim's borderline OCD would not allowing him to just leave them on the floor. They'd been living together long enough that they all had their little routines.

The moment he was in arms reach, Jim handed him the plate of pancakes and John started shoveling them into his mouth, ravenous after eating nothing all day but a few biscuits earlier. Jim shook his head and got busy cleaning the batter bowl, up to his elbows in suds. Jim was meticulous, scrubbing it until it shined, while John watched in fascination. When they'd first moved in together, the three of them had tried to divvy up the chores but then Jim would end up redoing anything John or Seb did anyway. Eventually they realized it was just easier to have Jim do it in the first place. The one thing Jim refused to do however was go shopping, claiming it was boring. That was the one thing he trusted John and Seb not to cock up, but it didn't stop him from making the list of things they needed and getting annoyed when the other two deviated from it, buying beer or Hobknobs or anything Jim deemed unnecessary.

When Jim had finished with the dishes, cleaning John's plate as well, he dried his hands and turned towards John. They smiled at each other for a moment before John closed the distance between them and hoisted Jim up onto the counter, standing between his parted legs. They kissed each other languidly, with Jim running his fingers through John's still slightly damp hair.

"I've got a date on Friday."

"You've always got a date." Jim said, uninterested.

"I like him." John said, slipping his hand under Jim's t-shirt and placing it on the small of his back.

"You like everyone." Jim said making a face.

"I don't like you all the time." John countered, making lazy patterns against Jim's skin.

Jim opened his mouth wide, being overdramatic as usual, pretending to be insulted. "And after I just made you pancakes?"

"You're right, I'm sorry." John said, capturing Jim's lips again. He moved his hands so they rested on Jim's groin, tracing his cock through the thin fabric of his pyjama bottoms, teasing it to hardness. Jim lifted his hips to assist with the removal of his trousers and pants as John pushed them down.

"You know we eat in this kitchen." Jim said as he sat bare-arsed on the counter. "Filthy bitch."

John pushed up onto his tiptoes and sucked at Jim's bottom lip, his hands resting on Jim's thighs. "Oh you love it."

They kissed hungrily as John stroked Jim's cock, thumb rubbing over the head. Jim wrapped his legs around John to pull him closer while he grabbed the door handles of their cupboards. John pulled away from the kiss and bent his head down, taking Jim into his mouth.

"So when do we get to meet this new guy?" Jim asked, panting heavily as John swallowed him down, wasting no time. "Oh fuck." Jim cried out as he felt himself reach the back of John's throat.

John pulled off to answer. "Seb met him today at the coffee shop. I think I'd like to take him on a few dates before I introduce you."

"Why?" Jim asked, offended. "Am I that unseemly."

"Not at all." John said, flicking his tongue out and licking away the bead of precome at the tip of Jim's cock. "Our situation can be a little overwhelming to some people."

"So?" Jim asked as John swallowed him again, sucking at the head and teasing the foreskin with his tongue. Jim groaned and smacked his head against the cupboard. "If they can't handle it then they don't deserve you."

John pulled off again but not before placing a kiss to the tip. "I suppose not. It's just that he's bloody gorgeous. Wait till you see him Jim."

"Hmm, bring him round for tea sometime."

"Hmm." John shrugged noncommittally, taking Jim down to the root. His head bobbed between Jim's legs as he used the perfect amount of suction and just the tiniest hint of teeth.

"I'm home." Seb called from the front hallway.

"Kitchen." Jim called out, followed by an enthusiastic, "Holy Mother fucking hell."

Seb walked in and placed the carton of cigarettes on the kitchen table, along with the bag of takeaway.

"Hello darling." Jim smiled at him. "Oh my fucking god."

John chuckled around Jim's prick and continued sucking. Seb walked over and leaned over John to kiss Jim. Jim responded enthusiastically, kissing Seb as he thrust into John's mouth. Seb pulled away from the kiss to go pull out their dinner.

"Did you get any –Jesus fuck – pot stickers?" Jim asked, watching Seb unload the bag.

Seb lifted up the container and shook it for Jim to see. Jim nodded happily and then let his eyes flutter closed. "Christ, how long have you two been at it?" Seb asked as John brought Jim to the brink and then pulled back again.

"Oh about twenty minutes or so." Jim answered him breathlessly.

"Isn't your fucking jaw tired?" Seb asked, gently running his fingers through John's hair.

"Are you offering to take over, tag him out?" Jim asked with a smirk.

"Or why don't you just fucking come already?" Seb asked, wiggling his hand under John to squeeze Jim's sack. Jim arched his back as he came, shouting curse words until John sucked every last drop. John pulled off and stood up straight, leaning forward to kiss Jim. Then he went over and kissed Seb, who groaned when he tasted Jim in his mouth.

"Do you want me to take care of that?" Sebastian asked, placing his hands on John's crotch and feeling his evident arousal.

"Food first." John said, giving Seb a lingering kiss before pulling away.

Jim jumped down off the counter, pulling his bottoms up. He went over to Sebastian and attacked his lips, practically climbing the taller man like a tree. John shook his head and grabbed a container of pork fried rice and some chopsticks, settling on the sofa in front of the telly.

"Hey, what do you think you're doing?" Jim asked, his attention being pulled away.

"Eating." John said as if this were obvious.

"Not on the sofa." Jim said sternly.

"Yes daddy." John said rolling his eyes and getting up; joining the other two back in the kitchen. The three of them sat down at the table and tucked into the food. John got a beer for himself and Seb while Jim glared at them unhappily until he got tired of it and gave up.

After dinner, Jim and John sat down to watch telly while Seb went out onto the balcony to smoke. Jim had forbidden any cigarettes in the flat so Seb was exiled out onto the balcony or else he had to smoke before he came home. The only exception to this rule was after sex.

John and Jim were cuddled together watching some quiz show, waiting for Seb to come back. When he did, the three of them headed to Jim and Seb's room. John had a room of his own but that didn't mean that he didn't share with the other two every once in a while. It was a strange arrangement and not one many people understood, but it worked for them and none of them cared enough about what other people thought to stop.
