Poison breaks from the kiss to drop his head back. He uses the headboard to push himself toward each thrust, hips rising to meet Jack's.

"I need-- I need--" Fuck he can barely think let alone articulate. His mouth hangs open as he tries to breathe. His back hurts from trying to hold the position but it's so fucking worth it when he gets the intense thrill. "Jack 'm gonna come. Don't stop don't stop--"

Poison actually runs into Jack's chest when the feeling hits. When he comes he curls forward like he's trying to trap the feeling - he lets go of the bed and blankets to clutch Jack instead.
