[Yokuutsu]

Vincent kisses him back, nipping at him a bit. This could be worse, a lot worse. He whimpers at he's pinned, essentially. He tries to squirm away a bit, but can't find any purchase to do so really. So he's at Don's mercy and whimpers again at the idea.

(Is it bad all I can think is of the fanfics with alpha/omega dynamics XD)
