A twisted couple's story begins with an abnormal request: "I want you to train my girlfriend." She is already completely shaved bare, and with her boyfriend's permission, the public filming takes place as an unforgiving training show. The hardcore training menu includes extreme stretching with five fingers inserted into her anus, 4P gangbangs with simultaneous vaginal and anal penetration combined with spanking, restrained irrumation using bondage gear, piss-drinking showers, and more.
