"Jackass-" It takes every iota of brainpower he has to growl that out- all he can do after is turn enough to bite down on the nearest patch of skin of David's that he can reach. Course the next slick twist of his fingers makes the bite a soft, open mouthed kiss wrapped around another low whine. Not his fault he's kind of a slut for this. He enjoys it. No shame in that. Definitely no shame in holding himself up with his hands and slowly fucking himself back onto David's fingers for a few moments, just to relish the burn.
