This video features submitted footage originally published by the SM magazine "Mania Club" editorial department at Sanwa Publishing. The submitter, Hirohiko Tsukushi, is a well-known figure among SM enthusiasts. The woman appearing in the video is Chika (slave●name), a masochistic woman who, by fate, was taken in by Mr. Tsukushi and shaped into a true masochist through rigorous training. Over more than a decade of intense discipline and physical modification, Chika’s body has been transformed into that of a perfect slave●woman. Her nipples have swollen to the size of a baby’s penis, her labia grotesquely elongated, and her childless vagina widened to the extent that two adult arms can fit inside. Her anus has also been stretched to allow a woman’s arm to enter without resistance. Additionally, her originally pea-sized clitoris has been enlarged further through the application of male hormone creams and is kept in a constant state of stimulation. After nearly ten years of deep-throat training designed to produce penile-like pleasure deep in her throat, she has completely lost her gag reflex. This video allows viewers to witness the extreme physical and psychological transformation of Chika, subjected to training so intense it would render an ordinary woman unconscious. Also included is footage of Keiko, another woman kept as livestock by Tsukushi, berating Chika for the grotesque enlargement of her nipples, instilling deep feelings of guilt. Further scenes depict training to stretch Chika’s labia even more by hanging weights, whipping her body, and making her perform blowjobs while simultaneously experiencing pleasure from the weights pulling on her labia. Experience the depth of Chika’s masochism and the compelling allure of a true female masochist.
