It's been three years since I started living with my father-in-law at my husband's parents' house. I had a good relationship with him and lived a comfortable life, but my only worry was our nighttime activities. My husband wanted to "make a baby efficiently," and our loveless, robotic sex never satisfied me. My desire continued to grow with each passing day, and finally, one day, I reached my limit, when I was masturbating ecstatically out of sight of others, and it seemed my father-in-law had seen me.
