When I was about 10 years old, I would hear my parents having sex down the hallway, and I would get mad because I could not sleep. I could hear the bed shaking and my mom and dad moaning. By the time I was 13, I grew to love their lovemaking sessions. My mom would talk dirty and have loud orgasms. I discovered that this was a good time to masturbate because I was turned on. I would time my orgasm to happen at the same time as my mom's. It was always hard the next morning to act like I didn't hear them.
