A hot spring trip for two people, a man and a woman who drown in pleasure by hitting each other's bodies with lust...Chiharu (provisional name) is 59 years old. She said, "A woman of the same age as me is an AV ... I wonder if I can do it ..." When she was a lecturer at a cram school, she married a serious and methodical colleague and became a full-time housewife.She doesn't get pleasure in SEX with her husband who has little experience with women, and she loses confidence with a married woman who wants children and avoids SEX.After that, she had a partner in an unfettered relationship, but not for the last few years.In search of her last memories as a woman, a mature woman goes on a journey with the man she met for the first time. "I learned that SEX, which is not for the purpose of making children, is fresh... I learned that it's okay to have more fun."
