From the Showa to Reiwa eras, this ultimate sadist and university professor, Sadomaru Oni, has trapped over 400 women in a snare of shame and humiliation. He recorded his heinous acts on video: imprisonment, object insertion, bondage, enema, forced excretion, double penetration, urine drinking, bit gag, nose torture, nipple torment, anal torture... Everything SM is here. Recorded woman ■いろは (30s, Apparel Shop Manager) had her self-respect stripped away and was made to submit through facial humiliation. Her body freedom was taken with hemp rope binding, her nipples pinched with clothespins, and her face contorted relentlessly with a nose hook. He urinated on her while she was still clothed, reducing her to a human toilet. ■あずさ (30s, Cram School Teacher) had her mouth violated with fingers, her nostrils probed with objects. She was bound to a pillar and forced into oral service. Her untouched anus was tormented with fingers or objects before being made to defecate through enema. ■サクラ (40s, Housewife) transformed a celebrity wife who craved sexual dominance into a slave. By heightening her sensitive anal sensations, she was manipulated into begging, 'Please insert your penis.' ■仁美 (20s, OL) had her wild sex life tamed through torture training. Spread-eagle bondage and anal torture, followed by enema to excrete thick feces.
