A male slave is collared and leashed, beginning his transformation into a pet for his mistress. She trains him in chastity, denying him orgasms while she fondles and torments his trapped cock. Ball-busting and verbal humiliation ensue, with the slave forced to lick his mistress's boots and clean her cum from her pussy. The grand finale? A cum-eating lesson, where the slave's release is devoured by his dominant trainer.
