After my mother-in-law passed away, I started living with my father-in-law. My husband works for a foreign company and is always busy, so I had a lot of time alone with my father-in-law. Then, on an unusually hot summer day, something happened. My father-in-law, who had always supported me, suddenly attacked me. From that day on, he kept asking me for sex every day. It continued for a year, two years, and before I knew it, I had grown fond of the perverted relationship, and it lasted for four years.
