This happened a couple of days ago. I was back home one evening as I walked past my parents’ room, I saw light in their room as the door was slightly ajar. Curiosity got the best out of me and I peeked in. What I saw completely shook me to the core. It was parents having sex. My mom was riding my father and she was riding him like there is no tomorrow. He had one hand on her ass while with the other, he played with her tit. For some strange reasons, that scene got me turned on like I had never before. I could almost immediately feel my pussy getting wet, he spanked her and that was too much for me bear. I rushed to my bathroom and got me off to that thought. I was done in no time.
