Sherlock did indeed stay where he was. Watching John leave gave him a rather nice view of his arse in motion, oh it had the sexiest little jiggle in it, just enough to hold but not too big. Perfect.

He wasn't surprised when John came back with a condom. Of course he couldn't tell John that he would never get any diseases from him, but he really didn't want a barrier between them. Not for the first time ever, and especially not when it was with John.

He wanted to feel EVERYTHING.

"That is unnecessary." he said, looking down at the condom. I know I am clean, and I am certain that you are too."
