Poison moans into Jack's mouth and squirms beneath him, trying to fuck into his hand. Then be gasps and plants a hand on Jack's chest to shove him back a little - just enough for Jack to have a good view. He'd said he wanted to see. Poison would hardly deny him that.

He gasps, eyes falling shut as he feels that kind of desperate closeness. He looks almost distressed right before he comes and the pleasure washes over his face, changing distress to euphoria.
His hands tighten wherever they are and he curls forward, just a bit, like he's trying to trap that delicious feeling.

"Oh fuck yes."
