I Am Addicted To Sex With My Son Who Is Not Related To Me By Blood. Miu Shiramine

When I was young, my mother died of illness. I vaguely remember her face, but it's fuzzy. My father ran a company, so we could live luxuriously, but he was never home and I was lonely. Half a year ago, that father brought Kumi-san home. She somehow resembled my mother, but Kumi-san is not my real mother. Kumi-san treats me like her real son, but... I somehow disliked that kindness. I didn't know why myself, but I finally realized. I was conscious of Kumi-san as a member of the opposite sex.
