NACR-901 The first woman was my old man's mistress Sumire Mizukawa

When I was young, my parents got divorced. After entering university, I stayed at my father's place, but there was a source of trouble. That was my father's mistress, Sumire-san. One day, Sumire-san, who works at the cabaret club run by my father, asked me to take photos for promotional materials. As she got more excited during the photo shoot, she kissed me, and despite my lack of experience, I hesitantly received her guidance.
