Maybe trying looking up ourXXXlife. They've got paid content but there are a few full length vids up on places like xhamster. It's a lot of sharing the wife with friends and coworkers. Kind of like pro porn but home video quality.
I was still friends with one of my exes. She lived in a different town at the point and she was just telling me about her life. She met a guy and I asked how the sex was. She gave me details of their sex and it was hot thinking about this girl I used to fuck being with someone else.
