Bound at the wrists and ankles, a man lies helpless on the cold floor as his femdom mistress looms over him, her heels clicking ominously. She orders him to masturbate, her voice a whip crack, as she watches, her expression one of bored disdain. His hand moves feverishly, his breathing ragged, until she barks, "Stop!" He freezes, his cock throbbing. "You will not cum until I say so," she informs him, her smile cruel. She pulls out a notepad, writing down detailed instructions for his jerk-off sessions, each one ending with the same humiliating command: "Clean it up, slut."
