This release is a compilation of works previously featured in the SM magazine "Maniac Club." Belonging to the SM circle "Slave Club," office lady Kumi, treated as livestock, is rented out and thoroughly disciplined as a female slave under her master's orders. A true masochist, she finds purpose in absolute obedience to her owner. This time, the request goes beyond mere use as a sexual toy or toilet—she is to be subjected to extreme cruelty to satisfy her deep craving for torment. [Scene 1] Ordered to masturbate as a greeting in front of numerous club members, Kumi undergoes immediate anal training. Her anus is stretched with fingers and fitted with a bell-equipped anal plug, then she performs a seductive, begging hip dance. For her shameful display, she is punished with whip strikes, forced to endure intense pain. [Scene 2] To reinforce her status as the lowest slave, she is made to clean a men's urinal with her tongue, then immediately perform a blowjob on a member's cock. [Scene 3] Bound tightly, Kumi is toyed with by members, forced to insert an ultra-thick dildo into her pussy to stretch her hole. Once fully opened, she performs self-fisting, climaxing amid wet, lewd sounds. [Scene 4] After a flogging, her breathing is controlled to increase suffering. As she drifts in and out of consciousness, a barbed wire gag is locked around her mouth and wrapped tightly around her body. Her nipples are tortured with electric shocks, leaving her gasping for breath. [Scene 5] Outdoors, bound and helpless, Kumi is treated like a toy as members douse her violently with hoses and buckets of water. Despite the endless torment, she utters words of gratitude with a blissful expression—revealing the ultimate masochist.
