In a dimly lit dungeon, a crossdresser kneels, awaiting his mistress. She approaches, clad in leather, her heels clicking on the stone floor. She inspects him, running a gloved hand over his stockinged legs, his silken panties, his bound breasts. "You need training," she says, her voice echoing. She introduces him to his new world: the weight of a chastity device, the sting of a crop, the pleasure of pain. She teaches him to embrace his femininity, to revel in his humiliation, to serve. By the end of the session, the crossdresser is a changed creature, eager for more lessons in his new, sissy self.
