Abel's jumpiness causes his hips to jerk forward, but Cain swallows him down no problem. It's the slight buckle in the other man's knees that gives him some warning, but he doesn't pull off fast enough before Abel comes, and he gets most of it in his mouth.

He grimaces as he swallows, pulling off and moving his hand to Abel's cock instead and keeps jerking him off. "Fuck, has no one ever sucked you off before either?"
