Bound at the wrists, a muscular, tattooed man finds himself at the mercy of an unseen captor. The command is simple yet taunting: "Jerk off until you cum." He's left alone, the weight of his thick, uncut cock hanging heavy between his legs. The room is dim, the air thick with anticipation. He grips his meat, the veins pulsing as he strokes. His grunts echo, his body tensing as he fights the urge to cum too quickly. He's a cum slave, and his performance is being judged.
