The mistress, a dominatrix extraordinaire, begins her slave's chastity training with a humiliating ritual. She forces him to watch as she teases her own body, bringing herself to the brink of orgasm while he's helplessly locked away. His pathetic whimpers of need only serve to amuse her, and she delights in his suffering. She then proceeds to train him in various tasks, all while keeping his cock locked away, ensuring he remains her submissive, eager-to-please toy.
