Married to a businessman. No children. Shortly after getting married, her father-in-law, who lives with her, began to feel unwell, and the wife had to take care of him. When her husband was busy with work, he didn't pay her any attention, and the stress and frustration of their marriage was on the verge of exploding. One day, while taking care of her father-in-law's private parts, she began to crave his cock, and they had a physical relationship. However, her aged father-in-law was not enough to satisfy her, and the masochistic wife, who has sex with her father-in-law's doctors, cried out in joy as she orgasmed over and over again.
