"God, yes," Barry breathes as Derek relaxes and takes it, everything he's ever needed and never known to want, "Just like that." Barry cups Derek's cheeks, carding his fingers through his dark hair as he starts to move, little thrusts at first, then more as he sees how perfectly Derek takes it.

"Someday," he says, panting as he slides into the wet heat of Derek's mouth, "I want to make you come, just like this. I want to fuck into you and know you feel it, I want to make you feel so good, Derek. Just as good as you make me feel."
