In a stark, dimly lit room, a woman stands over her bound partner, a wicked grin on her face. She orders him to masturbate, his hands tied behind his back, forcing him to use only his body to pleasure himself. His moans fill the room, echoing off the cold walls, as he struggles to maintain the pace she demands. She smirks, enjoying his discomfort, as she watches him writhe in pleasure-pain. His cock glistens with pre-cum, his balls tighten, and with a final command, he releases, his cum splattering onto the floor between his spread legs. She steps back, satisfied, leaving him panting and alone in his bondage.
