Chapter Text
I expect you to be home in an hour. JW
Or? SH
Receiving picture message...
You took the foot out of the freezer? It can’t thaw! The experiment would be ruined! SH
One hour. JW
John sent the message and grinned, leaving the foot on the table. Sherlock would be home in about two hours, guessing that John would never be so mean as to follow through with his threat. Pity. It was an interesting experiment, according to Sherlock. But it would be worth it. It truly would.
John, put the foot back in the freezer. I am on the way home, but there is traffic. SH
You have six minutes left. There’s a nice puddle around the foot now. JW
John! SH
Five minutes, thirty eight seconds. JW
He heard the front door slam with less than thirty seconds left and grinned. Time for the game to start.
“John! John, put the foot back in the freezer! I’m here, I have thirteen seconds to spare, put it back right now!”
John waited for Sherlock to run into the room, for him to realize there was no foot on the table before he started. “Freeze.” He smirked when Sherlock immediately ceased speaking and froze. Sherlock always did love when he gave orders in his military voice.
“What do you think you are doing here?” He eyed Sherlock, watched him tremble and smirked. He had discovered just how much Sherlock liked his military voice a few weeks ago when he had had to use it during a case. Sherlock had grabbed him and dragged him into an alley and had been desperate to fuck him.
“J-John-”
“Explain. Now. What do you think you are doing here?” John walked closer to Sherlock, seeing that he was already turned on and making his way to desperate. A thrill went through him at the sight.
He watched Sherlock swallow hard. His lips curled in a smirk. “I suggest you start explaining before I drag you in front of my commanding officer.”
“I was....I was...”
Sherlock was scrambling to find some sort of excuse. It was almost endearing to watch. But he had to keep to the part. John stopped in front of Sherlock and crossed his arms. “Sounds like you have stumbled into an active war zone for no reason.”
“N-No, I-”
“Shut up!” John barked, watching Sherlock’s lips snap together. Sherlock was hard, stretching his trousers, his cock leaking. He leaned closer, enjoying the sight of wide eyes staring at him. “Tell me what you are doing here.” He ordered, looking at Sherlock, willing him to make something up, to play the game with him.
“I wanted to see you! Y-You saved me a week ago, I wanted to see you and say thank you. I n-never even learned your name...”
His eyes lit up. Perfect. His voice stayed gruff and he leaned closer to Sherlock, watching his breathing get more and more erratic. “Well. I am off-duty for the next couple of hours. I’m sure you can find a way to give me a proper thank you.” He watched Sherlock’s eyes go even wider, his pupils dilating until his eyes were almost black.
“I-I’d love to. Please tell me your name?”
Sherlock sounded almost hesitant, shy. He was getting into the game. He was so obviously turned on, falling into the role of the shy civilian.
“Captain John Watson at your service Mr...?”
“Sherlock! Sherlock Holmes!”
John almost grinned at how quickly Sherlock stumbled to get his name out. But he kept himself in character at the last possible moment. “A pleasure to meet you Mr. Holmes.” He smirked when Sherlock shivered at the word pleasure. “What did you have in mind as a proper thank you?”
He watched Sherlock almost immediately fall to his knees. John was glad of his choice of outfit now. It had taken some digging in his closet, but he had managed to find the clothes he had worn whenever he was off-duty in Afghanistan. Fatigue pants, military boots (not laced in case he wanted to take them off in a hurry - which, if this went according to plan, he would), and a tight white t-shirt. His dog tags completed the outfit. From the looks Sherlock was giving him, it had been a success.
“I want to touch you Captain. Please. Let me thank you properly.”
How could he could refuse a pretty offer like that, with Sherlock between his legs, fumbling with his pants? He couldn't.
“Go ahead. I want to see what that pretty little mouth of yours can do.” John growled. He watched Sherlock finally get his pants unbuttoned and then yank them down his hips. Sherlock immediately went to work, his lips descending on him.
John groaned, his head falling back as Sherlock pulled out all the stops. His fingers immediately dove downward to tangle in Sherlock’s hair, tugging him closer. “That’s good, ahh...” Sherlock was determined to show his enthusiasm, swallowing him down to the root and back up again to tease at the slit. He would not last long.
“Yes, keep that up.” It was a struggle to stay in character when he wanted nothing more than to tug Sherlock up, bend him over the couch and fuck him until he screamed. “You’re very good with that mouth of yours Sherlock.” He felt Sherlock tremble when he purred his name. “Keep it up. I want you to make me come.” John ordered him.
In a second, Sherlock’s hands were on him, teasing at his balls and stroking his thighs while his mouth worked him even more eagerly. John tightened his fingers in Sherlock’s hair, panting. “Yes, just like that. Fuck, that sweet mouth of yours...” He moaned again and tugged on Sherlock’s hair again, trying to warn him.
Sherlock only sucked harder, his fingers everywhere at once, determined to drive him over the edge. John snapped his hips forward and came, so hard that he was barely able to keep standing. He leaned back against the couch and chuckled as Sherlock pulled away and looked up at him, his eyes dark.
“Bloody hell Sherlock.” John grinned, unable to keep up the stern soldier act after that. “Take it you liked that?”
“Yes. But I am going to make you pay for threatening my experiment.”
Sherlock smirked as John’s eyes went wide with lust. My turn.
