A married woman in her fourth year of marriage. I live with my husband's father. Busy husbands often go on business trips and tend to be away, and frustrated wives masturbate without husbands and wives. One day, a cheating partner's courier came and had sex, but my father-in-law was peeking again. And my father-in-law asks for my wife's body with the fact that I witnessed masturbation and cheating scenes. I was threatened by my husband and opened my crotch because I could not refuse. Furthermore, at night, I was made cum many times by my father-in-law who hates being fucked.
