A married woman's heart and body swaying in hot springs and love. A beautiful 25-year-old wife with a youthful smile, married to her first and only lover, joins a hot spring trip seeking new experiences, confessing, "Since I've only been with my husband... I want to discover a new world." As she soaks in the outdoor bath, she becomes aware of a man other than her husband. Shy yet responsive, her body trembles under his caresses, passionately sucking his erect cock. Her fair skin flushes red as she's enveloped in pleasure, surrendering herself completely to the man until the journey's end. An episode of a married woman whose heart and body are transformed by the trip.
