You try

"Sam! Fuck! Get off me!" You forcefully shove Sam backwards, and he rolls onto his back, cock jutting up at you. You glower at him and point towards the living room. "Out!" Sam looks suitably chastened and picks himself up from the floor. He opens his mouth, but you cut him off. "OUT!" But instead of leaving, Sam kisses you, pressing his body against yours. Infuriated, you move to push him away, but then his fingers find your pussy, and remind you of just how close you were to cumming. In your moment of distraction, Sam hooks his hands behind your thigs, and with a heave, lifts you up.

Down below, his rod is now pressed against you, and up above Sam continues kissing you with passion. You taste yourself on his lips, and in the steamy shower you decide to just go with it. Just for a bit. He knows he has to pull out, and if not, you'll make him. You can induldge for a little while. Taking your lack of resistance as assent, he lines himself up, not even needing his hands for the job, and pushes in.
