Rena, a married woman, decided to secretly sell herself to a secret club introduced by an investment company due to the debt her husband had taken on. The club catered to clients with hard-core SM fetishes. Rena, an innocent and chaste married woman, shed tears even during the oral service at the interview, but that was just the beginning of her horrifying humiliation and pain. Rena, who cried from the shame of being bound and sobbed from the humiliation of enema, gradually became addicted to masochism, accepting anal plugs inserted at all times, suspension bondage, whips, candles, fist fucking, double penetration, and even anal insemination. She transformed into a married woman slave who accepts everything in her sobs... The first full-fledged SM work by Rena Aizuki, the first exclusive actress of Sanwa Publishing.
