The wicked man Sado Maruki torments various women held captive in a sealed room—his former student, housewives, a corporate secretary, a young heiress, an art college student, a flower arrangement master, and more. His acts include enemas, foreign object insertion, bondage, forced excretion, double penetration, forced urine drinking, gagging, nasal torture, nipple abuse, and anal torment—encompassing every aspect of BDSM. Each woman comes from a different background, yet all become victims of his cruel domination. Corporate secretary Natsumi is tortured with countless clothespins, while former campus queen Aiko, a breast-focused masochist, suffers bondage and severe anal abuse. Heiress Kana and her mother Kaoruko, both enema masochists, are forced into massive defecation, and art student Miwa has anal pleasure and enema fetishes forcibly implanted into her inexperienced body. Flower arrangement master Shizuyo is tormented with oral servitude and forced urine consumption, while housewife Risa endures the humiliation of enema-induced excretion, drenched in thick, cloudy fluid. Every woman falls under his brutal control, depicting an extreme world of sadomasochism.
