Married to a salaryman husband, no children. Shortly after getting married, the father-in-law living with them fell ill, and the daughter-in-law started taking care of him. The couple's sex life also suffered due to the husband's busy work schedule, leading to built-up stress and unmet desires on the verge of exploding. During this time, while attending to her father-in-law's genitals, she found herself craving a penis and engaged in a physical relationship with him. However, the elderly father-in-law couldn't satisfy her, so the masochistic daughter-in-law would scream in ecstasy during M-play sessions with his doctors.
