Ayano Mitsui has been a full-time housewife for 25 years, sharing separate bedrooms from her husband for a long time. She hasn't had sex with him in years. Though she never disliked intimacy, she grew accustomed to satisfying herself alone. One night, convinced that being with her son wouldn't count as cheating, she enters his room while he sleeps. Driven by pent-up desire, she meticulously licks his entire body and ultimately gives him a creampie, fulfilling his every need.
