Within the company, Kumiko (pseudonym) is a popular and beautiful office lady, but here her hidden masochistic side is exposed. Since childhood, she has harbored deep-rooted submissive desires, a trait that has matured into an unchanging sexual fetish. This video documents her gradual descent into becoming a sex-dependent cum slave●. It features various forms of SM play, including beatings, wax torture using Buddhist altar candles, full nudity abandoned in snowy mountains, gangbangs, anal torment, and intense orgasms induced by sex toys. Even amid intense suffering, she repeatedly reaches climax. Her internal struggle between masochistic urges and the rationality expected of a working adult is vividly captured on film. A rare SM documentary, it offers a highly specialized perspective for connoisseurs.
