Keiko 5 Who's the JAV actress in this video? Amateur? Name revealed!

This video compiles footage originally published in the BDSM magazine "Mania Club." Keiko is a woman who has vowed to serve as a sex slave and masochist under her master, Yodo Tsukushi, for the rest of her life. From childhood, she cultivated her masochistic nature through repeated self-bondage and masturbation. After meeting Tsukushi by chance during college, she began undergoing systematic training and breeding under his guidance. Even after graduation, while working full-time as a caregiver, she spends nearly all her time in a livestock shed, where she is trained 24/7, 365 days a year, to become a dedicated sex slave solely for her master. On days when her master does not visit, she follows assigned training programs—exercising vaginal contractions, performing oral servicing drills on dildos, filming videos of perverted masturbation, crafting custom fetish clothing, and writing fantasy stories and drawing illustrations—all in service to her master. This footage was shot by her owner, Yodo Tsukushi, at the request of the editorial department. It features a variety of training scenes, including piston-style spanking on a dildo mounted to a chair, blowjob servicing on a dildo attached to a mirror, beating during simulated foursomes, extreme rope bondage walks, dual-penetration teasing in BDSM attire, loaned-out training sessions, and anilingus servicing.
