At the exclusive female body torture club "Inkaku," various men gather to fulfill their desires, trading women as commodities. This time, following the previous incident, female college student "Rina" — who schemed against her beautiful university teacher — is auctioned off and purchased by a legion of otaku, then bound and stripped of her freedom. Taking full advantage of her helpless state, the otaku horde can no longer suppress their lust and descend upon Rina. A solemn ritual unfolds, where humiliation and pleasure intertwine, as they torment the beautiful sacrifice. At "Inkaku," no woman is beyond reach.
