For a time, there was nothing but the panting of breaths and the soft sounds of London outside the window.

Sherlock waited as long as he could, but eventually he was softening, so he pulled out with a soft sigh, taking a small dribble of a mix of lube and come with him. He got up, went into the loo, cleaned himself up a bit, them put warm water on a flannel and came back in.

"John. Roll over so I can clean you." He was gentle with his touch, knowing that John would be quite sensitive. He wiped the man down gently, then threw the flannel in the laundry bin.

He was quiet again. observing his friend.. but now something more.
