During her school days, Rimi was raped by her homeroom teacher Sawada and from then on, she was repeatedly subjected to sexual training after school. Ten years after graduation, she was living a happy married life as a young wife, but one day she was stopped by Sawada while passing by and forcibly taken back to his house. From that point on, she began to endure relentless SM training like a snake… Rimi suffered from disgust and guilt, but forgot the ecstasy of her masochistic pleasure and fell into madness, ultimately descending into a double life of intense sex with her husband and being a mistress.
