This release compiles videos originally featured in the SM magazine "Mania Club," faithfully recreating the daily life of Keiko, a woman living as a masochist. She has pledged her entire life to serving as a sex slave under her master, Yodo Chikushi (pseudonym), dedicating herself to perpetual sexual servitude. Keiko, who developed her masochistic tendencies from childhood through self-bondage and masturbation, was discovered and trained by Chikushi during her university years. After graduation, while working part-time in elder care, she continues to live 24/7 in a livestock shed, fully devoted to her role as a sex slave. On days when her master doesn't visit, she follows a strict regimen: vaginal contraction exercises, oral servicing lip training, filming self-abusive masturbation videos, crafting custom fetish wear, and writing erotic fiction and illustrations. The footage was shot by her owner, Chikushi, at the request of the editorial department, and includes scenes of sexual servicing in the livestock shed as well as forced lesbian sessions with Chika. Key scenes include being tormented in a full BD costume, slapped with slippers while climaxing with sex toys, brought to orgasm by Chika using a five-finger penis glove, stimulation via a triple-pronged device pleasuring her clitoris, vagina, and anus, punishment with a leather paddle, pre-rental arousal masturbation, and breath control using a urine-soaked paper diaper. Unlike Chika, Keiko is petite and slender, intentionally unaltered, trained specifically as a sexual service animal designed to arouse men and extract semen through skilled techniques. During early training, she was conditioned to service with her mouth, vagina, and anus, but to differentiate her from Chika, anal intercourse has been strictly forbidden. Currently, only fingers or slim vibrators are used to stimulate her sensitive anus—thicker toys are prohibited. According to Chikushi, Keiko is scheduled to offer her anal "second virginity" on her 40th birthday. *Content may vary depending on distribution method.
