This man is evil. He teaches obscene SM to a chaste housewife. He imprisons the secretary he inherited from the president and repeats various rapes. University professor Sadomaru Oni recorded his evil deeds on video. Bondage, forced insertion of foreign objects, restraint, enema, forced excretion, double penetration, forced urination, monkey gag, nose torture, nipple torture, anal torture... all kinds of SM are here. The recorded women are Reiko (40s, bureaucrat's wife), who, due to the strict upbringing she received in her childhood, becomes aroused by indecent and immoral acts. She is a celebrity wife who is tormented by anal torture, enema excretion, and smearing. Nanako (30s, teacher) is a voluptuous housewife teacher who wants to become a sex slave with a different personality from her daily life. She reaches masochistic ecstasy through enema excretion with her legs wide open and bound, and through the humiliation and shame of urination and defecation. Maki (40s, corporate employee) is a kind woman who serves her faith, but when her masochistic symptoms flare up, she falls into serving a sadist as a masochistic pig. Shibuko (30s, housewife) has a masochistic fantasy deep in her heart, which has been dormant for a long time. She awakens to anal sensations through enema torture and anal play.
