Piano teacher Michiko Arima (pseudonym) was a woman who had long desired punishment. One day, through social media, she met S, the father of one of her piano students, and they began a master-servant relationship. The details of this are thoroughly documented in her confessional memoir. Recognizing her deep female masochism, S decided to go beyond simple punishment, subjecting her to various forms of training including gang rape, enemas, bondage, and anal torture. Among these practices was a unique game in which she recorded her own humiliating acts in photos and videos and submitted them to BDSM magazines, publicly showcasing her growth as a slave to fetish enthusiasts. This release compiles selected portions of her self-submitted training records, sent under S's orders. Her inner transformation and emotional shifts within the master-servant dynamic are carefully depicted.
