I went back to my parents' house for the first time in a while to tell them about my marriage. There, my girlfriend's bad sexual tendencies exploded. She started doing erotic things in front of my parents... While greeting me at the entrance, she started touching my butt and gave me a deep kiss. While we were resting in my room, we immediately had sex. Our sex got more and more exciting, and we did standing doggy style and cowgirl position where my parents could see us from the living room. While I was telling my parents about my marriage, she played with me with a remote vibrator. And then, for the first time in a while, my parents and I were sleeping alone together...
