In the languid summer countryside, I lost my virginity... During summer vacation, I, a student, returned to my father's house after a long time. That night, unable to sleep because of the heat, I accidentally caught a glimpse of my uncle and his wife Reika's sex. Reika, whose face seemed kind during the day, was sweating profusely, her large breasts swaying wildly as she moved her hips intensely. Her image lingered in my mind even the next day. When I suddenly looked up, Reika was smiling at me.
