A couple, alone on a hot spring trip, immerse themselves in pleasure, throwing their passions at each other's bodies... Chiharu (temp name), 59 years old. "I thought, could I do it too, seeing women my age in AV..." Married to a serious and meticulous colleague from her days as a tutor at a cram school, she became a full-time housewife. Unable to find pleasure in sex with her husband, who had little experience with women, and losing confidence as a wife who wanted children, she avoided sex, deepening the rift with her husband... They divorced after three years of marriage. Although she had partners in non-binding relationships afterward... she had been out of touch for the past few years. In search of her last memories as a woman, the mature woman embarked on a trip with a man she had just met. "I learned that sex not for the purpose of making babies is fresh... and that I can enjoy it in many ways." The mature woman, mesmerized by the long-absent erection, shows a straightforward reaction to desire and pleasure, trembling with excitement.
