This release compiles videos originally featured in the SM magazine "Mania Club," offering a realistic portrayal of a woman's life as a masochist. Keiko is a woman who has pledged herself to her Master, Yusumichi Chikushi (pseudonym), vowing to serve as a sexual slave for the rest of her life. Since childhood, she repeatedly engaged in self-bondage and masturbation, and during university, she met Chikushi by chance, who began training her and ultimately shaped her full identity as a masochist. Even after graduating, she continues working in caregiving while undergoing 24/7, 365-day training in a slave shed to become a dedicated sex slave. On days her Master does not visit, she follows strict self-imposed routines—performing vaginal contraction exercises, lip training for blowjob service, filming self-degrading masturbation videos, crafting custom fetish outfits, and writing fantasy stories and illustrations—living each day immersed in a fulfilling masochistic lifestyle. The footage includes scenes of play at a hot spring inn, morning blowjob sessions and window-side sex during business trips, public street blowjobs leading to orgasm, and intense climax scenes performed at windows fully exposed to the outside, all showcasing her complete devotion as a true female masochist.
