For over four decades, from the Showa to the Reiwa era, Satowamaruki, a demonic sadist and university professor, has driven more than 400 women to the brink of shame and humiliation. Every one of his heinous acts has been recorded on video, comprehensively covering every aspect of BDSM. The footage meticulously documents extreme sexual abuse beyond limits—kidnapping, foreign object insertion, bondage, enemas, forced excretion, double penetration, forced urophagia, gagging, nasal torture, nipple torment, and anal abuse.
The women featured come from diverse backgrounds, yet all were selected as targets of his brutal domination. ■Iroha (30s, apparel store manager) has her dignity stripped away through face abuse, is completely immobilized with tightly bound ropes, has her nipples clamped with clothespins, her face grotesquely distorted by nose hooks, and is urinated on while fully clothed, ultimately reduced to a human toilet.
■Azusa (30s, cram school teacher) suffers finger penetration into her mouth, her nasal passages violently probed with foreign objects, is tightly bound to a pillar and forced into oral sex, and has her untrained anus violated with fingers and objects before being made to defecate via enema.
■Sakura (40s, married woman) is a wealthy housewife craving sexual domination, now enslaved. Her sensitive anal nerves are heightened until she pleads desperately, "Please put your cock inside me."
■Hitomi (20s, office lady) is a free-spirited OL subjected to crushing discipline. Bound with legs spread wide, she endures intense anal torture, is forced to expel thick feces through enemas, and is ultimately brought under complete control.
