Hey everyone. This is my first time writing in the Sherlock fandom but was watching it the other day and felt inspired this is just a little fluffy piece with some smut at the end. It's slash of the Sherlock/John variety. I hope you enjoy.

I do not own Sherlock.

John pulled his coat tighter as he made his way from the clinic to the pub for a beer. It was Wednesday night, his usual night to have a few drinks with Lestrade and a few others from the Yard. Surprisingly, Sherlock had messaged him earlier to let him know he too would be attending. John had been shocked, usually Sherlock only goes if John forces him to, arguing that it would be good to get out of the flat for a while. This time however, Sherlock was coming of his own volition, no arm twisting involved. John couldn't help but feel a little suspicious.

It was a cold evening, so John hurried the short distance from the clinic to the pub, rubbing his hands as he went to keep them from going numb. As he walked in, he was happy to see that the pub was moderately busy but not too crowded, the main reason they had decided on Wednesday night for pub night.

He spotted Lestrade, Donovan and Anderson as well as a few others sitting around a table in the corner and made his way towards them. He was only a few metres away when Sherlock suddenly appeared. It was obvious from the flushed skin that he had already had a few drinks. John couldn't help raising his eyebrows in question, it wasn't like Sherlock to drink much of anything, let alone enough to be noticeable.

Before John could ask what was going on Sherlock stepped forward, sweeping John into his arms and pulling him flush against his chest, before bringing their lips together in a very thorough kiss. John stood frozen for moment, before the shock wore off and he started kissing back enthusiastically. Winding his arms around Sherlocks neck to pull him even closer as Sherlocks tongue made its way into his mouth. Sherlock tasted like oranges and some kind of alcohol and John couldn't get enough. His lips were soft and the contrast it made with his rough stubble as it rubbed against John's skin sent shivers running down his spine. Sherlocks strong arms held him close, and John wished he could stay here, safe in Sherlocks arms, forever.

He had been head over heels in love with Sherlock for so long and worked valiantly to try to keep his feelings hidden, knowing that Sherlock would never return them. But, thought John, Sherlock must've figured it out, like he figures everything else out and he wants me back! His mind cheered with joy just as Sherlock began to pull away, gasping for breath as John tried to right himself.

"Sherlock" John whispered, leaning his face to rest against Sherlock chest.

"Excellent, excellent, but I must compare the data" Sherlock mumbled to himself, and John froze, a fissure of worry running through him.

Sherlock pulled away, leaving John feeling bereft.

"Sherlock?" John said again, this time in question.

"The experiment!" Sherlock cried, as if it was obvious. "I must collect more data." And with that the consulting detective hurried off.

John stood motionless… an experiment. Sherlock hadn't realised his feelings for John, he was doing an experiment. He should have known better than to get his hopes up. Stupid John, he berated himself as he turned slowly back to his table of friends. A table of friends who were all staring at him with mixtures of pity and shock on their faces. They had obviously just seen everything. That was the problem with being friends with detectives, they were well adept at reading a situation.

John swallowed thickly, trying to push all the hurt aside as he made his way over.

"Alright everyone?" he asked in a calm voice that was clearly not fooling anyone. Thankfully they all played along, the looks of pity lingered but he was greeted like normal. A few claps on the back as he sat down and joined in the ongoing conversation, something about the local rugby match that had been played the weekend before.

It was a little while later, when he had gotten up to get a drink from the bar that he saw Sherlock locking lips with a good-looking redhead, who was at least a head taller than John. They were really going at it and John felt his insides turn to led as he watched the two kiss. His heart pounded in his chest and he thought he may throw up as the man moved and pushed Sherlock against the bar. John looked away then, he didn't want to see any more. He grabbed his drink and hurried back to the table, wondering if he should just leave. He didn't think his heart could take seeing Sherlock kissing someone else, especially not after he had finally found out what it felt like to have Sherlocks lips on his own.

He sipped his beer, not really paying attention to the conversation going on around him. He wanted to turn to see if Sherlock was still kissing that other man, but he refused to do it, refused to give in. Sherlock and he were not together, Sherlock was allowed to kiss anyone he liked, even if John wished he wouldn't.

He heard a loud exclamation and looked up to see Sally staring in shock. The whole table turned to see what it was. Sherlock… kissing a petite blonde woman. He had her wrapped tightly in his arms as he kissed the daylights out of her.

To his chagrin, John felt tears spring to his eyes. He took a few deep breaths as his eyes took in the spectacle. What the hell was going on with Sherlock tonight!? To John's knowledge he hadn't really kissed anyone the whole time they had known each other, now he had kissed at least three people in the space of 30 minutes. The woman's arms went up to wrap around Sherlocks neck in a mocking parody of how Johns arms had been wrapped around Sherlock earlier.

He jumped up, knocking his chair back in his rush to leave. Nope, nope, it was too much, he needed to leave, to clear his head.

"I'm gonna go" he said to his friends, not even bothering to come up with a pitiful excuse as he turned to leave.

"John, wait! I'll walk you home" Greg called, but John was already hurrying out the door.

"Just what is Sherlock playing at?" Dimmock growled, glaring at the consulting detective. The whole yard had a soft spot for John Watson. "He should feel bloody privileged that John would even look his way. Instead, he leads him on and breaks his heart, kissing other people in front of him." Everyone made sounds of agreement.

"We all know Sherlock isn't one to do things sensibly, he probably doesn't even realise what's going on." Greg defended Sherlock, but honestly, he was pretty mad himself. The look on John's face when he had seen Sherlock kissing that woman had damn near broken his own heart.

"Bah" Sally scoffed. "The man can tell you your life story within five minutes of meeting you, there is no way he could be clueless about John's feelings for him. John looks at him like he hung the moon. He knows how John feels about him, he just doesn't care."

Greg wanted to argue but it was hard to fault that kind of logic. He had a hard time believing that Sherlock wouldn't be aware of John's feelings for him. The whole Yard had been placing bets on whether they would ever get together.

At that moment Sherlock dropped himself into Johns vacated seat, his face pink and his lips swollen. His hair and shirt were dishevelled where people had gripped both tightly. The whole table scowled darkly at him. Sally looked like she was seconds away from throwing her drink at him.

Greg cleared his throat awkwardly.

"Might be best if you move on for the night Sherlock, everyone's a little tense."

"Yes, I can see that" he said running his eyes over the assembled group. "What is the issue?"

"You're the issue!" Sally hissed.

"Generally speaking, yes, that's true. But what specifically seems to be the issue this time" Sherlock asked.

Greg pinched the bridge of his nose.

"Everyone is a little upset with the way you treated John."

"John?" Sherlock asked in surprise. "If you're talking about the kiss, I will tell you that he seemed quite amenable."

"Of course, he was bloody amenable" Dimmock growled. "The poor man has been in love with you for ages, so what do you do!? Lead him on then flaunt your other conquests in his face. You've damn well broken his heart. Don't know what he even sees in you!"

Sherlock sat frozen for a moment.

"Excuse me?"

"You bloody well heard me! You know how John feels about you, how could you do that to him. All he ever does is love and take care of you, defend you, he deserves so much better than the likes of you!" Dimmock glared at Sherlock.

Sherlock tried to sort through the chaos that was his mind. John was in love with him? He knew about his own feelings for his best friend. He hadn't even dared to hope that John might reciprocate. Sherlock even felt physically attracted to John, a rare occurrence for him indeed. Hence the experiment tonight. Sherlock had needed to kiss John to see how it felt then compare it to his feelings when he kissed other people. He wasn't used to feeling this way, so he had needed to deal with it the same way he dealt with most things, facts and logic. The results had been undeniable, kissing John Watson had been unlike anything he had ever experienced in his entire life. He had kissed several other people just to confirm his findings. But kissing those people had produced nothing, no shivers up his spine, no hardening of his cock, no warm glowing feeling that made Sherlock feel as though his heart was going to explode.

"Where is John?" Sherlock asked.

Greg answered before anyone else could get in an angry reply.

"He left, when he saw you kissing that blonde woman. He- ah, he looked pretty upset."

Sherlocks heart clenched at the idea of John being hurt over anything, let alone something he had done. Was it possible that John cared about him the way that he cared about John?

"I need to speak to John, this was all a misunderstanding" Sherlock said urgently, jumping up from his seat and racing out the door. Surely John had gone home after leaving the pub, he thought as he raced towards Baker Street. He threw open the door to their flat, calling John's name, only to find it empty. No lights were on, the kettle wasn't boiling away and there was no sound of John puttering around in his room.

Sherlock slid into his usual seat, gripping his hair in frustration.

How could he have been so stupid not to deduce John's feelings for him? The truth was that he probably had on some level realised it but had chosen to ignore them, not sure how to deal with it until his own feelings had grown too strong to ignore. Now he had hurt his best friend. Now he risked losing his best friend. He felt sick at the very thought, what if John wanted to leave now? Sherlock wasn't sure he would cope without John in his life.

He tried calling John… once, twice, three times. No answer. Hours passed. He sent messages but no response came. He grew more concerned the later it got. Should he go out and search for him? What if something had happened? He had just decided that he would contact Mycroft and see if he had any idea where John was when he heard footsteps on the stairs and then a key in the lock.

John stumbled in and froze, obviously surprised to find Sherlock standing in the living room waiting for him. John's eyes ran over him, lingering on his still slightly swollen lips. Sherlock felt all the air rush from his lungs as John's face crumpled at the sight. Ever the stoic soldier, the expression was gone a moment later.

"Sherlock" John greeted as he turned to shut the door and hang up his coat and scarf. "Wasn't expecting to see you here."

Sherlocks brow furrowed in confusion for a moment, scanning the tense set of Johns jaw, oh, John thought Sherlock had gone home with one of those people from the pub. Had obviously spent the last few hours walking around in the cold, judging by his wind bitten cheeks, thinking Sherlock was getting it off with some stranger. Sherlocks own heart broke at the thought of his John walking alone through the city, miserable, imagining Sherlock with someone else.

For once in his life Sherlock wasn't sure what to say.

"Right," John said after a long pause. "Think I'll head to bed; it's been a long night."

"John, wait" Sherlock said softly.

John paused and looked back. "Not tonight Sherlock. I- I just can't."

Sherlock nodded as John turned and walked away, his door shutting quietly behind him.

Sherlock knew he would get no sleep that night. He sat and tried to organise his mind palace to calm himself, but everything kept leading back to John.

Eventually he gave up, and with a huff made his way silently to Johns room. The room was dark as he crept in, only a slither of moonlight shining in through the window to light the way.

John was curled up in a ball on his side and Sherlock could see that the other man was shaking.

John spun around as a floorboard squeaked.

"Sherlock!" John croaked. "What are you doing in here?"

"I- I just had to see you" Sherlock whispered. "You're cold."

"Yeah, no shit Sherlock" John said, his teeth chattering as he pulled the blanket up higher.

"Here" Sherlock stepped closer and began rubbing his hands over Johns body over the blanket, trying to create more warmth.

John glanced at Sherlock but didn't pull away.

The shivering eased as John felt some warmth return to his body, it really hadn't been a smart move to go walking through London in the freezing cold for hours, but he had needed time to think.

"What do you want Sherlock?" John asked wearily.

Sherlock couldn't think of how to explain, so he acted impulsively as he was want to do and leant forward capturing Johns lips in a soft kiss. They were so soft.

John shoved him hard, causing Sherlock to nearly fall over.

"What the fuck do you think you're doing Sherlock!" John shouted, eyes narrowing. "I will not be a part of any more experiments!"

Sherlock felt like he had been punched in the gut when he heard John's voice break on the last word.

"No! No, no, John. This isn't some experiment!" Sherlock cried, hurrying back to Johns side.

"You literally kissed me earlier this evening and said it was some experiment, so excuse me if I don't believe you" John said with a huff.

"I will admit that perhaps, that wasn't my greatest idea. But I needed to be sure." Sherlock explained.

"Sure of what?" John asked.

Sherlock's heart raced in his chest, "sure of my feelings for you."

"You're feelings for me?" John asked sceptically.

But he had stopped shouting, so Sherlock took that as a good sign and continued on.

"Yes. You see…" Sherlock cleared his throat nervously before continuing, "it has recently come to my attention that I am in love with you."

"In love with me?" John said, blue eyes looking dazed.

"Yes, irrevocably, impossibly, hopelessly in love with you. I see all of you John Watson and there is not a single part that I do not love."

John sat motionless, staring at Sherlock in complete shock, his face flushed a soft pink. Sherlock spoke as if there was no doubt, as if he was just stating a simple fact.

"Of course, I am not so foolish to think that you love me back John. But I hate to think of you upset with me and so had to explain my earlier actions. As you know, I am not always great with sentiment, with emotions. What I feel for you I have never felt before, not just the love but also the fact that I am sexually attracted to you."

John let out a little squeak, but Sherlock continued wanting to get it all out now that he had started.

"I had to be sure that my feelings weren't stemming from a lack of sexual release, so I decided to compare kissing you with others and how that made me feel."

"And – and how did it make you feel?" John asked breathlessly as he pulled back the blankets and started to stand.

"Well," Sherlock said thoughtfully. "Kissing you made me hard in seconds, made my heart race, my palms sweat, and I felt as if my whole body was tingling."

John blushed harder at Sherlocks blunt assessment.

"Kissing those other people, made me feel… unsettled. They tasted all wrong, felt all wrong, I- I didn't like it."

John started to smile broadly and took a step closer to Sherlock.

"The experiment made me realise that I want you and only you in every way possible."

John stepped even closer and slowly wrapped his arms around Sherlocks waist, enjoying the shiver that ran through Sherlock at the touch.

"Lestrade said you were upset. I'm sorry if I hurt you" Sherlock whispered, looking down into Johns eyes.

"I was upset" John admitted. "Because I love you too and it damn near killed me seeing you with anyone that wasn't me."

"You love me?" Sherlock asked in genuine surprise.

"I love you so damn much I don't know what to do with myself," John admitted with a wry grin.

"No one has ever loved me before" Sherlock said in disbelief.

"Well, I do. I love all of you to Sherlock."

And with that John pulled Sherlock down into a gentle kiss, their third and John thinks their best of the evening.

Sherlocks arms wrapped around John's thin waist pulling him close, hands clutching the back of Johns shirt as though making sure the other wouldn't disappear. John's hands clenched and unclenched on Sherlocks arms as the detective deepened the kiss, desperate to get a taste of his John and as his tongue ran over John's, Sherlock didn't think he had ever tasted anything so incredible. John groaned as Sherlock pulled away and began trailing kisses down his neck. Soft little bites that left the skin pink and glowing.

"Mine, my John" Sherlock kissed into soft skin, over and over again.

"Yes, yes I'm yours Sherlock." John groaned, spreading his legs so Sherlock could push one of his between them. Moaning loudly as Sherlocks lean thigh rubbed deliciously against his cock. John couldn't help himself, desperate for any friction he began riding Sherlocks leg, throwing his head back as he moaned, his body thrumming. Sherlock pulled back from where he had been kissing, to watch John lose himself to his pleasure. The sight before him only serving to make Sherlock even more desperate.

Long lean fingers made their way under pyjamas, running over lean muscles and course chest hair. Sherlock pinched a nipple and revelled in the way John shuddered at the contact.

"Pl-Please Sherlock, I want to feel you against me" John said as he reached up and began undoing the buttons on Sherlocks shirt. His fingers fumbling in his desperation.

Sherlock took Johns hands gently into his own, causing John to look up at him confused. "Get undressed and lay on the bed, I will handle this."

John jumped to obey pulling his pyjamas off and scooting back on the bed until he was laying on the pillows, intending to enjoy watching Sherlock getting undressed. His breathing becoming laboured as he watched all the pale skin being slowly exposed to him. Sherlock obviously enjoyed having an audience. Eventually, the consulting detective stood naked, his cock hard and dripping and John couldn't take his eyes off it. Sherlock grinned as he slowly crawled up the bed and John very much felt like he was being stalked by a predator.

"You are so beautiful" Sherlock whispered.

John spread his legs in a clear invitation and Sherlock settled between them with a content sigh, a hand coming up to cradle John's face. John leaned into it, turning his face to place a soft kiss on Sherlocks wrist just as Sherlock rolled his hips, causing them to rub together deliciously. John threw his head back with a moan, hands reaching out to clutch at pale skin as Sherlock did it again. Pre-come already slicking the way. Sherlock started slow, with Languid thrusts against John but soon began to speed up, his movements getting more erratic, as John moved beneath him. He had wanted this for so long. They both had.

Sweat gleamed on Sherlocks skin, his face flushed pink and John didn't think he had ever seen anything so beautiful.

"I do apologise John" Sherlock panted. "I fear I won't last long."

John groaned at the idea of Sherlock already being so close to the edge. John reached down and gripped Sherlocks arse, pulling him in even harder, "Fuck John" Sherlock stuttered.

"I want you to cum, cum on me Sherlock, all over me, mark me as yours."

"Fuck, fuck yes John. Going to cum all over you. You are mine, no one else's" Sherlock growled, moving even faster until he let out a loud moan, his whole body shuddering as his orgasm tore through him. John couldn't tear his eyes away from the sight of Sherlock coming completely undone, revelling in the feel of warm cum landing all over his belly and chest. He was still achingly hard but at the moment he was too focused on Sherlock to care.

After a few moments Sherlock seemed to come back to himself, he moved himself slightly off John, just enough to reach in between them and wrap his hand firmly around John. It only took a few firm strokes and John was quivering through his own orgasm, gasping as his cum joined Sherlocks all over his belly.

Sherlock rolled to the side, but didn't let go of John, pulling the shorter man firmly against his chest and placing a gentle kiss on his temple. He reached blindly for Johns discarded pyjamas and gently cleaned them both up.

"That was perfect" John murmured looking at Sherlock in awe.

"You are perfect" Sherlock said back, placing another kiss to John's temple and running his fingers through the short hair, revelling in the feeling of having John in his arms.
