Newlywed RIE worked as a cram-school instructor before marriage. After becoming a full-time homemaker, the loss of structure and tension leads her into unfamiliar thrills such as gambling and nightlife. Once she gets a taste for them, her self-control collapses and her buried sexual appetite pours out. She has slept with several men in the past two months and reportedly still keeps two regular lovers. Her appearance is demure, but her secret lust has grown so intense that she volunteers to perform in porn and have it satisfied.
