Couple having hot sex by the pool

Reminds me of my ex wife, me and her dated for about 5 years got married a year later stayed married for 3 years but divorced 5 years ago ( 9 years being together) we weren't heavy sex addicts but we fucked frequently. I remember after being together for 3 years she invited me over to meet her family. now I was nervous the first two years of us dating and couldn't even get the idea of meeting her parents but it was bound to happen one way or another, and it was a football night her WHOLE family was there. I remember finally seeing everyone and my girlfriend and she greeted me to everyone, surprisingly they all seemed to like me. throughout the night my girlfriend at the time was signaling sexually acts and I understood quickly. we both decided to go out for a swim and and ended up fucking by the pool both naked raw fucking no condoms, after an hour we finished she got up cum running down her leg jumped in the pool after putting on her top for the bikini I pulled my swim trunks up jumping in (this pool had jets) she swam to a jet rubbing her pussy on one before putting on the bottom piece luckily we didn't get caught as her family were focused on the game. As years went by we never talked about the pool incident and later on divorcing... I'm currently dating her sister whose expecting our second child
