Since childhood, there's been one fleeting yet intensely lustful memory etched into my mind. My father disappeared when I was born, and my mother passed away from overwork, so I ended up living with my aunt, Izumi. Her warm, gentle nature deeply touched me. Then one day, at a mixed bath, I saw an adult woman's body up close for the first time. That sight struck me like lightning. From that moment on, I developed an overwhelming sexual desire for Izumi. Struggling to control my urges, I could no longer suppress my feelings—and finally confronted her.
