This is a story from when I was still in elementary school. My father's friend built a new house, and my father and I went to visit him to celebrate... What happened that time was so shocking that it's hard to put into words. In the evening, my father and his friend were drinking all night. His wife, Sayuri, gave me and the child a bath. It was my first time seeing a naked adult woman, and I was excited. Later that night, I peeked at the couple having sex. My fantasy didn't stop, and the next day, when I was alone with Sayuri, it became a reality!
