So I actually had an entirely non-cracky, non-slashy drabble prepped for today, but then I realised this was drabble number sixty-nine, and I just couldn't resist passing up an opportunity like that. You'll get the non-ridiculous one tomorrow.

John lets out a sharp hiss as Sherlock rolls over, clipping the side of John's head with his knee. The smaller man ducks out of the way.

"Watch where you're putting those limbs, you lanky beast."

"Yes, well, if you would jus t relax and uncurl yourself a bit, I suspect this would go a lot smoother. I can't get near you if you keep your knees bent."

The two men tussle around on the bed a bit in an awkward attempt to re-position themselves. Sherlock is rewarded for his efforts by John rolling over his hand, one sturdy hip pinning the long, pale digits to the mattress. Sherlock frees himself with a grunt.

"Sherlock, can we just give this up as a lost cause for tonight?" John gestures irritably to his now-flaccid cock. "Or hell, let me take care of you, and then hopefully I'll be more in the mood, and you can return the favour. We don't need to do everything you've read about on the internet right away, you know."

The world's only consulting detective scowls and raises his head and shoulders up off the mattress, as if to study the geography of the bed and the men contained within. "Honestly, John. We can figure this out. I'm sure I understand the basic mechanics of a mutual blowjob."
