My parents were both swingers and into the hotwife scene. My dad would travel often for months at a time for work so my mom would find ways to satisfy her urges. She would regularly have guys come over when dad was gone and fuck her. Once my brother and I were a bit older, did my parents explain things. Sex was an approachable topic in my family and my family was very open about talking about sex. Mom tried her best to hide the guys, they usually came over late at night. They would have sex when she thought both my brother and I were sleeping. Our house was small so I definitely heard everything going on.

When I knew she had a guy over, I would sneak out to stand outside her bedroom door and listen. I could hear her moaning and occasionally screaming. It always got me hard and turned me on. I always thought my mom's moans were hot. As the intensity of her getting fucked increased, it would have me throbbing in my shorts listening to the heavy breathing, slapping of her ass, or the clapping of her getting poounded.

Eventually I got brave enough to crack open her door if she didn't lock it which she usually didn’t. Making sure the hallway light was off, I was able to see her naked, getting fucked in different positions and sucking on his cock. Especially if the bathroom light was on then enough light would flood into the bedroom to where I could see better since she always left trhe lights off in the bedroom.

Watching her getting fucked and listening to her moans and breathing would put enough in my mind for me to immediately go to my room and masterbate multiple times throughout the night.
