To celebrate their only son's marriage, the couple decided to live together with the newlyweds. Their daughter-in-law, Himari, was bright, kind, and treated the family with great care and warmth. However, a few days later, the husband overheard that Himari was dissatisfied with her marital sex life. Shortly after, when he fell ill with a cold and took to his bed, Himari kindly nursed him back to health. By chance, she caught sight of his erect cock. From that moment on, his life would change dramatically.
