It's been three years since Rin's husband died. I was so worried about my elderly father-in-law that I continued to care for him without paying attention to his remarriage. However, even so, Rin is still young and in the prime of her life. And sometimes Rin begins to feel the remnants of her late husband in her father-in-law, and asks for a cock that erects while caring for her even when she is old. Rin begged for sex by seducing him under the guise of nursing care, and gradually became a lewd constitution that he could not sleep without a rich kiss and caress with his father-in-law.
