Thirty-year-old housewife Rio Saeki instantly captivates with jewel-bright eyes and a charming smile. Friendly, delicate, and alluring on the surface, she also hides a deeply horny side. After three sexless years, she shyly admits to masturbating to porn as often as eight times a week. Once this still-untapped beauty undresses, her angelic smile turns lustful as she loses herself in her first extramarital sexual encounter.
