In a private, dimly lit room, a muscular, tattooed submissive awaits his master's command. Given the green light to masturbate, he eagerly strips off his briefs, revealing his thick, veiny cock. He grips it tightly, stroking from base to tip, his hips bucking with each pass. His master, seated nearby, observes with a mix of lust and dominance, his own bulge growing. The sub's breathing becomes ragged, his moans echoing in the room, but he knows better than to climax without his master's explicit order.
