52-year-old Fumino Nakayama's debut work. Having been in a sexless marriage for the past two years, she decided to appear in an adult video after discovering her husband's infidelity—an unusual motive driven by spite toward him. With no prior experience of cheating, she appeared somewhat nervous at first, but once filming began, she became deeply immersed in the sex scene, clearly enjoying herself to the point of losing awareness of her surroundings. Her natural expressions and erotic performance are the highlights of this release.
