One day, my father-in-law suddenly came to my house where I live with my husband. When I asked him about the situation, he told me that he had gotten into a fight with his mother-in-law and had run away from his parents' house, so I reluctantly allowed him to stay with me for just a week. During that time, I was left alone with my nightly duties, and when I went to my father-in-law's room to collect the laundry, I saw his crotch as if it was going to explode...When I realized it, I was so fascinated by him that I was masturbating. However, the scene was filmed, and my father-in-law eroded my body by just rubbing it with his mouth, just 3 cm.
