The mother of the first son of her mother

We are married with our parents. Recently, my father's habit of drinking was bad, and my relationship with my wife was beginning to flourish. Moreover, in the night, my depression had only accumulated. One night, the light is leaking from my parents' bedroom, and my mother is talking about my father's thing. Father ordered his mother to join him, but he went out of the room with anger. Then she comforted herself comfortably. I regretted having seen my parents' sexual life, but erection did not fit during my mother's masturbation. One day, when I looked for my mother, I was taking a nap. Neither wife nor father. I was excited to remember my mother's masturbation, and touched the sleeping mother's body. My mother awoke to stop, but I forced her to take off my mother's clothes and suck into my crotch. The overflowing honey made me excited, and when I pressed my heart to the mother, my heart was inserted. The mother was warm and I immediately fired. But my erection did not fit, and when I inserted it into my mother again, I hit it hard more than a minute ago.
