The plump young wife in her fourth year of marriage is living with her father-in-law. My husband is busy, often goes on business trips, and I feel bored with my husband's job. My wife masturbates, but my father-in-law grins and denies love. One day, I had sex with a courier of a cheating partner at home, but my father-in-law considered it. And my father-in-law demanded my wife's body on the grounds of witnessing masturbation and fucking. I opened my crotch and refused to be threatened by my husband. Moreover, I was fucked by my hateful father-in-law at night and ejaculated many times.
