In a dimly lit dungeon, a submissive male is bound in intricate rope work, his body stretched and vulnerable. His dominatrix trainer, Daiko Fextar, oversees his extreme training, pinching his nipples and testicles with clamps, twisting and pulling for maximum pain and humiliation. The sub's cock is caged in a chastity device, denying him any pleasure as he's forced to endure hours of CBT and bondage, all while listening to his trainer's degrading commands through a headset.
