MILF Chihiro (pseudonym), 59, embarks on a hot spring trip with a man she's meeting for the first time—her first intimate encounter in years. Previously, she married a serious and meticulous colleague while working as a cram school teacher, then became a full-time housewife. However, her sex life with her husband brought her no pleasure, her desire for children remained unfulfilled, and their relationship steadily deteriorated. By the third year of marriage, divorce became inevitable. Afterward, she sought relationships free of constraints, but in recent years, she's had almost no romantic or sexual contact. Now, longing to create one final memory as a woman, she sets off on this journey with a stranger. Along the way, she discovers the joy of sex without the pressure of conceiving, experiencing new pleasures and sensations. Captivated by the sight of an erect cock for the first time in years, she trembles with desire, surrendering her body to pleasure. The full allure and passion of this mature woman reach their peak by the journey's end.
