DLDSS-499 From 9 a.m. to 6 p.m., while my husband is at work, I spend my time with my father-in-law in an intimate relationship. Mamimi Zenba

To support her lonely father-in-law after the death of his wife, Mami decides to move into her parents-in-law’s home with her husband. Her husband is kind, devoted to his parents, and above all, serious, neat, and meticulous. She thought marrying someone so earnest was the best choice, but their life together has become completely routine, and their nights are, of course, devoid of intimacy. One night, when Mami tries to soothe the restlessness of her heated body on her own, her private moment is seen by her father-in-law. The next morning, after her husband leaves for work, her father-in-law’s intense gaze and restrained desire are directed at Mami. Though she knows in her mind that she should refuse, Mami gradually begins to yield to the feelings and attention that ease the longing in her body.
