A woman in heels and a leather corset towers over her bound, naked slave. She takes his cock in her hand, her touch a mix of pleasure and pain. "You will not orgasm without my permission," she says, her voice stern. She strokes him, feeling him grow harder, but she stops just short of his release. She slips a chastity cage onto his throbbing cock, locking it tight. He whimpers, his body aching for more. She leans in, her breath hot on his ear, "You will learn to control your desires, slave. You will learn to serve."
