A special project taking married woman Eri (25) on a trip, with an unexpected twist—adding a mature woman to the journey. When Eri learns that another woman will be joining them, she feels uneasy, but gradually gives in both emotionally and physically as the Milf makes bold advances, awakening her latent lesbian desires. While she steps out of the room, Eri peeks in to find the Milf having sex with the man. Caught watching, she is overwhelmed by the Milf's intense yet tender teasing and torment, crying as she becomes aroused. Repeatedly brought to climax by the Milf's skilled touch, Eri watches as the three engage in a wild threesome, her emotions shattered, tears streaming down her face.
