"Nnnnngggg." Sherlock wanted to move, but he paused for a moment, giving John a second to breathe and get use to the feeling of being so filled up, so stretched.

His sharp nails dug into John's sides, leaving little bloody marks when he started to move, pulling out until only his glans remained inside, then thrusting hard back in, his bollocks slapping against John's arse.
