An evil man subjects a virtuous married woman to depraved SM training. He kidnaps his newly appointed company secretary and subjects her to relentless acts of humiliation. University professor Maruki Sado secretly records his wicked, inhumane acts. Confinement, foreign object insertion, bondage, enemas, forced excretion, double penetration, forced urine drinking, gagging, nasal torture, nipple torment, and anal abuse—every form of SM is gathered here.
The women featured each come from different backgrounds, yet all are driven by masochistic desires. ■ Riko (40s, bureaucrat's wife) developed an arousal toward immoral acts as a reaction to the excessively strict discipline she endured as a child. Bound tightly, she writhes in ecstasy during anal torture, enema evacuations, and feces smearing, her mature scat-masochist body trembling with pleasure.
■ Nanako (30s, teacher) is a voluptuous married teacher who desires to become a sexual slave, adopting an alternate persona separate from her daily life. With her legs forcibly spread and tightly bound, she undergoes enema-induced defecation and urination, indulging in the masochistic pleasure of humiliating piss-drinking and filmed urination scenes.
■ Maki (40s, organization employee) is a pious and kind woman devoted to her faith, but when her masochistic urges flare up, she degenerates into a masochistic pig serving sadists. ■ Shihoko (30s, housewife) has lived an ordinary life, yet her deeply buried masochistic fantasies awaken, leading her to discover anal sensitivity through enema torture and anal play.
