The slave, bound and helpless, is a canvas for the trainer's kinky desires. He whips her, each lash echoing in the room, her skin turning a beautiful shade of pink. He pushes a gag into her mouth, filling it completely, before unzipping his pants. His cock, hard and ready, slides into her wet pussy, stretching her. He fucks her roughly, using her body for his pleasure, as she's forced to take it, bound and gagged, her eyes watering with a mix of pain and ecstasy.
