Every weekend, the wife heads to a hot spring with her favorite young lover, Tsubame, indulging in intensely erotic moments. Drawn in by Tsubame's aggressive advances, she can't help but moan aloud. Their passion begins in the car and continues in the room, where she's immediately brought to squirting orgasms with vigorous fingering. They revel in pleasure throughout the baths, nights, and mornings. These repeated, natural encounters have become a uniquely special time for the married woman.
