[Chinese]NACT-024 My first woman was my old man's mistress Hibiki Otsuki

When I was young, my parents got divorced. After entering university, I've been living at my dad's place, but there's a source of trouble: my dad's mistress, Hibiki-san. One day, I was asked by Hibiki-san, who works at the cabaret club run by my dad, to take some photos for promotional materials. While being photographed, Hibiki kissed me as she got excited. I was confused but still received her guidance since I had no experience.
