In a cramped, dimly lit room, a nervous couple awaits the arrival of the girlfriend's friend. The friend enters, his eyes hungry as he takes in the girlfriend's curves. He wastes no time, pushing her to her knees and forcing his cock into her willing mouth. She gags but obediently sucks, her hands working his shaft as her boyfriend watches, torn between jealousy and arousal. The friend then mounts her, his powerful thrusts making her tits bounce as she moans, her pussy dripping with lust. The boyfriend watches, his dick hard, as his girlfriend is used for another man's pleasure.
