A new adventure begins, stirring the heart and body of a married woman on a hot spring trip. Though her marital relationship had been stagnant after their last hot spring getaway, it has started moving again. Yet unsatisfied with her husband's cold attitude, the married woman secretly longed to meet someone she truly desired. That wish comes true on this trip. Surrounded by a man she knows well and feels comfortable with, she relaxes in the hot springs. In the outdoor bath, she boldly sucks his penis and passionately rides him in the cowgirl position, chasing pleasure. The ecstasy continues later, as she quietly releases moans next to the room where dinner is being prepared, enduring deep penetration. Even after breakfast the next morning, they fondle each other in the open-air bath, her cries echoing with every thrust, driving her married desires higher and higher.
