A stern femdom takes her submissive through a rigorous training session, focusing on orgasm denial and chastity humiliation. She orders him to the floor, making him worship her feet while she strokes his straining erection. She edges him repeatedly, bringing him to the brink of ecstasy only to deny him release. His cock glistens with pre-cum, his balls heavy and tight, as he begs for mercy. Finally, she allows him a single, explosive orgasm, but not before locking him in a cruel chastity device. His moan of despair echoes through the room as she leaves him locked and denied, eager for his next lesson.
