"I'm baaaaaaack," John called as he pushed open Sherlock's office door.
"Jesus, John!" Sherlock barked. "What the hell are you doing here? How did you even know I was in here?"
John grinned in triumph. "Well you weren't at your little... uh, your um..."
"Barracks?" Sherlock supplied.
"Yes!" John cheered, snapping his fingers and pointing at Sherlock. "Clever you. So clever. So very very clever. And sexy. So very very-"
"Christ, John," Sherlock cut him off. "How often is this going to happen?"
John sauntered into his office, flicking the door shut with his foot. Very smooth. "How often will what happen, baby?"
"No," Sherlock shook his head vigorously. "No nicknames. I've let this go on long enough as it is."
"Mm, on the contrary Mister Pretty Eyes," John made his way over to the Major, dipping his hips in a sultry swagger. He was getting excellent at seducing Sherlock. "I don't think this has gone on long enough at all."
"Smooth," Sherlock grumbled and John grinned.
"Thank you Major Holmes," he said batting his eyelashes. He saddled up to his Major and plopped down on his lap. "Hi," he whispered, knowing for sure that that was very sexual sounding, and slid his fingers into Sherlock's hair.
"John," Sherlock warned, but John didn't loosen his grip.
"I wanna return the favor," he whispered, pressing his lips to Sherlock's ear. He was certain Sherlock would like that.
"No," Sherlock said firmly. "Not necessary."
John pulled a pouty lip. "Come on! I'm suuuper good at it, I swear."
"It's not for pleasure, John, it's for focus."
"And you need to focus," John crooned. All he wanted was to suck Sherlock's cock. Was that so bloody much to ask? Why did Sherlock make this so difficult for him?
"No. I'm plenty focused on the case."
"Fine," John replied, wrapping his arms around Sherlock's neck. "If you won't focus on me sucking you, why don't you focus on fucking me?"
That's really what John wanted anyway.
"John, I think we should make one thing very clear," Sherlock all but growled, putting a hand on John's knee. "I will never do anything sexual with you while you are drunk." He ignored John's groan. "Now. Do you have any new information?"
John nuzzled his nose into Sherlock's hair. "Pleeeeaaassse?"
"No."
John harrumphed, actually harrumphed, and stuck his tongue in Sherlock's ear. "Doesn't that feel good, baby?"
"We talked about nicknames, John."
Mm, was it John's imagination or was Sherlock's words coming out a bit...breathless?
Oh yes, he was definitely having an impact. He swirled his tongue. "Tell me how it feels," he murmured.
"It feels like you're slobbering all over the side of my head," Sherlock said, and then John was being shoved onto his feet, barely keeping himself from toppling over.
"Hey!" he cried indignantly. "I'm just trying to show you how good I can make you feel." He tugged his shirt down and tried to step closer.
Sherlock's arm shot out and a hand was placed firmly on John's chest. "John. Do you know how difficult you make things?"
John grinned. "You mean how hard I make things?"
"Clever," Sherlock rolled his eyes, but his hand stayed firm.
John's body was starting to wilt, the haze over his eyes thickening.
"You're tired," Sherlock murmured. "Go get some sleep."
"But I wanna sleep with you," John hung his heavy head. "I like being with you."
"Christ, John," Sherlock murmured. "How many times can one man hit on another?"
"It's your fault you sucked my cock," John tried to say indignantly. "Now I want you all the time."
Sherlock snorted. "You're right, sorry about that."
John was awake enough to snap his head up. "What? Don't be sorry! It was bloody incredible! All I want is to return the favor!"
Sherlock chuckled. "I know. But you can't John. It would... cross a line."
John giggled. "But I like crossing lines with you."
"I know," Sherlock replied grimly.
"How about you get drunk and show up at my barracks next time and then you won't feel so guilty?" John was excellent with plans.
Sherlock snorted. "Absolutely not."
"Why?" John whined. "Then we'll be even. I have no problem taking advantage of a drunk, sexy, delicious Major Holmes."
"Good god, how many different ways can you call me sexy?"
"Mm, lemme think," John slurred, "hot, pretty, gorg-"
"I was kidding," Sherlock said with a wave of his hand, "just go shut down your brain and get some rest."
"When are you going to sleep with me?" John asked. "Soon? I'll do better with waiting if you give me a deadline."
"John-"
"Wait, wait," John shook his head. He really was tired and he was starting to think he couldn't do much tonight in way of seducing his Sherlock, anyway. He could wait. "Don't say no again, okay? Just...just give me a kiss and I will go to bed, I swear."
"John-"
"Please?" John said sleepily. "Just a quick little smooch and then I'll be out of your hair and off to my dreams where you are very very naked."
Sherlock huffed a laugh. "Fine," Sherlock said. "One kiss."
John immediately puckered his lips and closed his eyes for his first kiss with Sherlock. Even tired, his body still thrummed excitedly. He'd been imagining what those pretty, pouty, pillowy lips would feel like for so long.
He was also excellent at alliteration while inebriated.
There was a soft pressure on his cheek and then Sherlock's hand was gone from his chest. John waited for a moment longer, frowning when nothing happened.
John's eyes fluttered open. "What-"
"You promised," Sherlock warned. "One kiss and you would go to bed."
John gaped. "Not on the cheek! On the lips!"
Sherlock shrugged. "You didn't specify."
"Sherlock-"
"Goodnight John," Sherlock said pushing him gently toward the door.
"Sherlock!" John tried again but his sleepy body was not cooperating in pushing back against his Major.
"Goodnight John," Sherlock murmured again and gave him a shove out the door.
