I lost my virginity in the countryside on a lazy summer day... During summer vacation, I was a student and had returned to my father's hometown for the first time in a long time. That night, unable to sleep due to the heat, I peeked at my uncle and his wife, Reika, having sex. Reika was covered in sweat, shaking her huge breasts and swaying her hips violently, which was completely different from the gentle face she had during the day. The image of her was stuck in my mind even the next day. When I suddenly came to my senses and looked up, Reika was smiling at me.
