Sadie: I am SO sorry this one took so long! I never forgot about it, dear anon, but it took me awhile to decide the direction I wanted to take it in.

It’s also a long one, so I’m putting a bit of it under a cut. If you’re still around, I hope you enjoy!

Jawn sat up and flipped his pillow over, then flopped back down. A few minutes later, he tossed to his other side. He couldn’t sleep. His mind simply would not shut off.

Everything was distracting. Every sound from outside was something that needed to be investigated. Every moving shadow. Every passing light from the window.

Most distracting of all, though, was the nappy that was fastened a little too snugly around his hips; the thick padding, just a little too warm. A little too crinkly when he moved. Tight enough to feel pressing against his cock, yet not tight enough to cause the right amount of friction needed for relief.

This was all Sherlock’s fault. If he hadn’t insisted that today be a ‘Jawn’ day, and hadn’t insisted on putting him to bed in a nappy, then he could just have a quick wank and get to sleep, no problem. He technically could just cup his hand on his front and rut against it while he squeezed…well, maybe…

No, too noisy. Sherlock would hear, and then Jawn would have bigger problems than just not being able to sleep.

Prick.

Jawn flopped over onto his back and stared at the ceiling. This was torture.

“For God’sake.”

Jawn startled at the sudden voice. Next to him, Sherlock sat up on his elbow and clicked on the lamp sitting on his bedside table. “What is the problem?”

Jawn blinked, and shielded his eyes with his hand. “Huh?”

“You’ve been tossing and turning for two hours now. What. is. the. problem.”

Jawn peeked between two fingers. “Can’t sleep.”

Sherlock snorted and sat up, blocking most of the light from shining directly into Jawn’s face. “Well, obviously. Why?”

Jawn lowered his hand and shrugged. “Dunno,” he mumbled.

Sherlock sighed and rubbed his hand over his face. “Fine. Come here.”

Jawn faltered. ‘Come here’ never usually led to good things. “What for?” he asked, uncertainty in his voice.

Sherlock adjusted his pillow and sat back against the headboard. “I know what puts you to sleep. Come here.”

Well, now Jawn was intrigued. Really, there was only one thing that Sherlock could be talking about. But was it really that easy? Just annoy Sherlock to the point of–?

Sherlock rolled his eyes and, before Jawn could react, reached out and took then smaller man by the shoulders, then heaved him facedown over his lap.

Now the panic began to set in. This was the exact situation that Jawn had hoped to avoid. “Wait, wait!” He scrambled to reach back and cover his backside with both hands. “I didn’t do anything!”

“I know you didn’t.”

Jawn tried to crane his neck to peer over his shoulder. What was going on back there?! “Wait…what?”

“As I told you before, I know what makes you tired.” Sherlock took each of Jawn’s hands and calmly moved them out of the way. “You’re not in trouble. Relax.”

Once he realized that he wasn’t going to get the daylights whacked out of him, Jawn’s initial panic subsided, and left him more puzzled now than he’d been before. “So what–?” he began to ask, and was promptly cut off by the flat of Sherlock’s hand thunking against his nappy. Then again. Then again. Jawn realized that Sherlock was purposefully *not* striking him hard enough to hurt.

In fact…it felt really, really good.

Jawn silenced his protesting and did as Sherlock asked, finally relaxing into the steady rhythm of firm, full-handed swats to his bum, each one sending muffled sensations through the padding, straight to his…well.

They were killing two birds with one very sensual stone tonight, it seemed.

Jawn soon found himself rutting against Sherlock’s thigh in time with each swat, and as the movements of his hips started to pick up the pace, so did Sherlock’s swats. Jawn’s breath came in quick pants; if he just had a little bit more…!

Sherlock’s other hand snaked under his waist, cupped the front of his nappy, and squeezed.

Jawn moaned and pressed his face into the mattress, his hips moving in frantic, jerking motions as heat began to pool in his lower belly, spreading to his thighs, and then…and then…!

Aaah.

Sherlock slowly removed his hand from Jawn’s front, and started to rub his padded backside with the other, while Jawn caught his breath. He said nothing for several minutes, while he listened to the smaller man’s breathing become steadier, more shallow…“Not every spanking has to be a punishment, you know.”

Jawn grunted and nodded his head without opening his eyes.

Loathe as he was to disturb the now-peaceful doctor, it would not do for either of them if he fell asleep over Sherlock’s lap. “Here, let Da’..” he said, and helped Jawn sit up and move back to his side of the bed, where he immediately started to doze off again, the moment his head hit his pillow.

Sherlock smirked, and tucked the blankets around him snugly. He always knew what Jawn needed.
