A married woman's heart and body swaying in hot springs and love. A newlywed couple on their honeymoon experience their first night together, both still virgins at marriage. However, their next sexual encounter comes a year later, as their marital life stagnates due to the husband's busy work schedule and late-blooming, passive nature. Entering their third year of marriage, the wife sets off on an affair trip. At an outdoor hot spring, she's approached by a new man and accepts her second lover in life. In the midst of passionate sex, a maid arrives, forcing her to remain silent as she's pounded to climax. That night, she reaches orgasm again through her first cunnilingus, and the following morning she eagerly takes his cock once more, losing all control. A series of events that fully unleashes the married woman's pent-up desires.
