A seasoned sadist, known only as Mistress, takes a new submissive under her wing for an intensive training session in BDSM. She starts with bondage, restraining the eager novice to a St. Andrew's cross, her wrists and ankles secured with soft yet unyielding ropes. The mistress then introduces her to a world of pain and pleasure, alternating between caresses and strikes with a variety of implements - a wooden paddle, a leather strap, a wicked cane. The submissive's screams fill the room, but the mistress, undeterred, continues her lesson, her own arousal growing with each mark she leaves on the quivering flesh. She finishes with a brutal, yet intimate, flogging, the submissive's tears mixing with her sweat, her body a canvas of red welts and bruises, a testament to her first day of sadomasochistic training.
