Picked up two young women who had just moved to Tokyo and invited them for drinks, unaware that one of them was a married woman, smoothly drawn into a calm and intimate atmosphere. As her friend considerately leaves for the bathroom, she gets turned on by having her beautiful pink nipples sucked. Riri, in a playful mood, craves a thicker and longer cock than her husband's, excited by the novelty of being in Tokyo for the first time. Extremely sensitive, she climaxes multiple times even before penetration, her intense reactions leaving a strong impression. Even as her friend returns to the room and watches, she keeps cumming repeatedly, completely lost in the pleasure of bareback sex, making for an incredibly erotic scene.
