A quiet woman with an uneventful job and life meets someone from her past through an app: the teacher who used corporal punishment on her during adult student role-play. He had already recognized her masochistic desires and now targets her voluptuous body, telling the inexperienced woman that he will teach her about men. Unable to refuse, she is pulled into hardcore submission training. He orders her to swallow every drop, repeatedly exposes and humiliates her in places where they might be caught, and insults her until she cums wildly while apologizing for becoming his degraded plaything.
