This release features a special video originally published in the SM magazine "Mania Club." The protagonist, Keiko, is a woman who has pledged to serve as a masochist and devote her entire life to sexual servitude under her Master, Yodo Tsukushi. Since childhood, Keiko has engaged in self-bondage and masturbation, and during her university years, she was completely domesticated by Tsukushi, becoming a full-fledged human pet. Currently working in elder care, she undergoes daily training as a sex slave in a livestock shed almost every day. On days when her Master does not visit, she follows a strict regimen in her assigned room—performing vaginal muscle contractions, oral servicing lip training, filming self-abusive masturbation videos, crafting custom fetish outfits, and writing erotic fiction and illustrations—shaping her everyday life around the ideals of masochism. This footage was shot by her Master at the request of the editorial department. The video includes a wide variety of scenes: naked exposure to a maid at a hot spring inn, morning blowjob and window-side sex, public street blowjob and climax, forced intercourse at a visible window, anal teasing, hallway blowjob and anal service at an SM hotel, spanking-fueled thrusting, and candle wax torture. In her early training, Keiko was strictly disciplined to service with all three orifices—mouth, vagina, and anus—but to differentiate her from Chika, anal intercourse was discontinued. She now only enjoys servicing with fingers or small vibrators, avoiding larger anal toys. Tsukushi has stated his intention to claim Keiko's anal "second virginity" on her 40th birthday. *Content may vary depending on distribution method.
