Locked in a cruel chastity device, the slave's days are filled with endless torment and denial. His femdom mistress, a sadistic beauty, delights in his suffering. Today, she orders him to service her with his mouth, his hands bound behind his back. As he struggles to pleasure her, she mocks his helplessness, his pathetic attempts to maintain his dignity. When she finally decides to give him relief, she makes him beg, his voice hoarse with need. She releases him from his chastity prison, laughing as he comes undone, his body convulsing with the force of his long-denied orgasm.
