This work compiles submitted videos sent to the editorial department of Sanwa Publishing's SM magazine "Mania Club," produced by known contributor Yodo Tsukushi. The woman featured in the footage is Chika (slave ● name), a dedicated female masochist who, by fate, came under Tsukushi's ownership and, after years of rigorous training, has transformed her body into that of a true masochistic woman. Due to over a decade of discipline, Chika's nipples have swollen to the size of a baby's penis, her labia grotesquely elongated, and her vaginal canal stretched so wide that two adult arms can fit inside. Her clitoris has grown even larger than a red bean and is continuously stimulated with topical male hormone agents. Additionally, she experiences penile-like pleasure deep in her throat, having undergone nearly ten years of strict deep-throat training during which vomiting was never permitted—now, her gag reflex has been completely erased. This extreme physical transformation, combined with her intense masochistic nature, makes this a must-watch for hardcore BDSM enthusiasts. In the nipple play scenes, a needle roller is used to further grotesquely enlarge her already deformed nipples, delivering ultra-fetishistic stimulation. She is also tormented using rubber bands tightly wrapped around her nipples and severe clamps biting down on them, depicted through various relentless methods of torture.
