A fleeting and obscene memory that sticks in my mind...By the time I could remember, my father had evaporated, and her mother had died from overwork, so I was entrusted to her aunt Izumi's care.However, I was shocked by her life with Izumi-san.The wonderful big breasts that grew on her Izumi-san's chest, and the naked body of an adult woman I saw for the first time in her mixed bath.I couldn't control her sexual interest in her Izumi-san, and I wanted her Izumi-san as per her desire.
