This work compiles videos originally featured in the BDSM magazine "Mania Club," offering a realistic portrayal of the daily life of Keiko, a dedicated masochist. Keiko has pledged herself to her Master, Yodo Chikushi, vowing to serve as a sexual slave for the rest of her life. From early childhood, repeated self-bondage and masturbation cultivated her deep-rooted masochistic tendencies. After being discovered and taken under the wing of Chikushi during her university years, she continued her training as a full-time sex slave even after graduation, all while working as a caregiver. She undergoes 24-hour conditioning in a slave shed, making her a genuine, innate masochist. On days when her Master does not visit the slave shed, she follows strict orders: physical conditioning, vaginal contraction exercises, lip training for blowjob service, filming perverted masturbation videos, crafting custom fetish wear, and creating fantasy novels and illustrations—fully embodying diverse aspects of masochism. The footage was shot by Master Chikushi at the request of the editorial department. The video features extreme masochistic acts such as a buttock-shaking dance accompanied by meticulous toe-sucking service, serving as an inn maid while completely naked and wearing an anal hook, and swallowing semen—scenes that represent the ultimate expression of female masochism.
