Mirei Shinonome spends a night alone with a male porn performer in this popular hot-spring date series. Formal speech is banned, they must hold hands throughout the date, and every surprise challenge must be obeyed. She blushes after kissing on a rainy mountaintop, gets intimate in a mixed bath, grows excited while they masturbate for each other, becomes aroused while bound with her robe sash, reaches new heights of embarrassment in baby role-play, and discovers a bold dominant side. Her natural personality and sexuality blend perfectly in this intensely erotic trip.
