A femdom mistress sets the rules for her male slave's chastity. He is to remain locked in a device of her choosing, denied orgasm until she deems him worthy. She films herself giving instructions, her voice laced with contempt for his weakness. The slave is to eat his own cum regularly, a practice she finds amusing and degrading. She makes him watch as she pleasures herself, taunting him with her own climax, knowing he cannot join her in release. The mistress promises severe punishment if he disobeys, her eyes gleaming with sadistic pleasure at the thought.
