A woman married in her third year of marriage. I live with my father-in-law. Busy husbands tend to go on business trips, and frustrated wives masturbate when there is no husband and wife. One day, the courier of the cheating partner came and had sex, but my father-in-law peeked. And the father-in-law demanded his wife's body on the grounds of witnessing masturbation and fucking. I was threatened by my husband to open my crotch because I could not refuse. In addition, the daughter-in-law who was hated by her father-in-law was raped many times at night.
