In a cramped, dimly lit room, a man's worst fears come true as his partner takes charge, determined to push his boundaries. She forces his legs open, exposing his erect cock to her relentless assault. Using both hands, she jerks him off roughly, her grip like a vice. As he squirms and moans, she begins to strike his penis with her closed fist, each hit echoing in the small space. His cock throbs, spurting cum, but she continues her brutal onslaught, intent on breaking him.
