Me and my wife went with my dad and my mom to Las Vegas.Nevada, and 1 of the first days that we were there we split up and we when our own separate ways. I saw my wife killing the elevator and go upstairs and then I saw my dad do the same thing.So I followed him up there. I caught my wife and my dad having s**.And I taped some of it , so I could show my mom. I kind of knew something was going on, but I didn’t know for sure until I taped it, we had the room right next to theirs.So I unlocked the door and I snuck in and I could hear my wife telling my dad that you are so much better than your son at having s**. I love it when you c** inside me. I knew my wife liked older men because when we went to visit her mom and dad, her dad and her were having s**.And that’s the first time that I got together with my mother in law , and she was really good in bed too. My wife had told me that she had been having s** with her dad since high school. Her dad was her first f***. Her mom knew about it but never said anything to me about it. Her dad had been f****** her even when we were married. Me and her mom started having s** a lot when they moved but in town. One time I even had s** with her dad. He sucked me off a couple of times when they moved back. I never told anyone about it. Until now. He told me that he was having s** with a guy that he worked with. After I showed my mom what I had taped she and I f*** every chance we got. My mom was so good in bed too.
