My mother had a bad past in love, but she overcame it, so now our family of 3 is living a very happy life. My father went to work, my mother stayed at home to take care of the children and take care of household chores, while I focused on studying for university entrance exams. It seemed like a very fulfilling life that every family wished to have until my mother decided to hire a tutor to tutor me. Ironically, that tutor was my ex-lover - who my mother had a very deep affection for and it took her many years to forget him. That day, my father went to work as usual, just me and my mother were at home, and when I saw my mother, the memories of that poor tutor also rushed back, he forced me into the study room and I went out to review the sweet "memories" with my mother, since then my mother was like spring. Another time, when I just came home from school, I opened the door and saw a nude scene of two people playing sadistic games. The more I cried and begged, the more active they became until he came out outside of my mother. After he left, I was angry and went to the bathroom to wash my mother's stains, but I couldn't control myself in front of her slim body like a young woman in her twenties, we had incest with each other.
