Four years after I got married to my husband, we moved to his parents' house where my father-in-law lives. I had a good relationship with my father-in-law and was living a happy life, but my only worry was the lack of sex with my husband. One day, when no one was home and I was masturbating, my father-in-law saw me. My father-in-law must have been sexually frustrated, and when he asked me to masturbate, I felt affection for him and masturbated with my hand right there and then. After that incident, my father-in-law came to me again...
