Tim's whimper is what makes Matt move one hand up from Tim's ass to trail up his body and to his neck. He doesn't squeeze to cut off oxygen but he holds Tim there, fingertips pressing into bruises that weren't made by him before doing the same to the ones that were, and his mouth is back on Tim's, rough and hard as he physically presses the small of Tim's back to push him even closer.

That whimper is one of the sexiest noises Matt has ever heard in his entire life.

It's the neck. Always, for Tim, it's the neck. Matt's other hand drifts down to between the clefts, nimbly touching the other's hole.

He shouldn't do this. He should stop, but he's making damn sure Tim can hear him even though his voice is even and smooth.

"Say it again."
