ADN-622 I'm addicted to sex with my son who's not related to me by play. Miu Shiramine

Description

When I was a child, my mother passed away due to illness. I vaguely remember my mother's face, but it's a vague memory. My father ran a company and we lived a luxurious life, but he was never home and I felt lonely. Then, six months ago, my father brought home Kumi. I felt that she looked somewhat like my mother, but she is not my real mother. Kumi treats me like her real son, but for some reason, I didn't like her kindness. I didn't know why, but I finally realized. I was aware of Kumi as a member of the opposite sex.
