This release features submitted videos from readers of Mania Club, an SM-focused magazine published by Sanwa Publishing. The videos were compiled by Tsukushi Hiroto, who documents his personal sessions with Chika (slave name), a masochistic woman under his ownership. Over many years of intense training, Chika's body has been completely transformed into that of a dedicated slave woman. Her nipples have swollen to the size of a baby's penis, and her labia are grotesquely elongated. Despite never having given birth, her vaginal canal is so stretched that two adult arms can fit inside, while her anus has been expanded to easily accommodate a full female arm. Her clitoris, once the size of a bean, has been treated with male hormone creams and constant stimulation to achieve further enlargement. After nearly a decade of strict deep-throat training—forced to experience pleasure deep in her throat while strictly forbidden from vomiting—her gag reflex has been entirely eliminated. This extreme, irreversible conditioning makes Chika a uniquely specialized figure, appealing only to the most dedicated fetish enthusiasts. Clad in a crotchless panty with a built-in paddle, she is whipped on her exposed vulva; even as the lash strikes her open labia, she screams in orgasmic agony, a deeply pitiable sight. The video also features her performing blowjob service, followed by a scene where she rubs ejaculated semen into her vagina like lotion instead of swallowing it, masturbating with the cum-smeared fluids. Due to her desensitized erogenous zones—her vagina widened from repeated use of electric vibrators and anal sex—she is filmed receiving anal penetration while a vibrator remains inserted in her vagina. In another highly fetishistic scene, Chika has vaginal clamps and an anal vibrator attached while performing fellatio on Tsukushi; even through mosaic censorship, the metal clamps on her labia and the vibrator embedded in her anus are clearly visible, creating an intensely niche visual experience.
