In this intense ballbusting session, the mistress takes control, her heels digging into her slave's testicles as she commands him to maintain his position. She torments him with chastity device adjustments, denying him release, and forces him to service her sexually. The mistress's dominance is absolute, her voice laced with sadistic pleasure as she orders her slave to clean her boots with his tongue, pushing his limits and pushing him to his breaking point, only to deny him again.
