Convinced my ex and her dad to have sex with each other about 3 years ago.

Convinced my ex and her dad to have sex with each other after finding out they both are into it. This was shortly before we broke up. We have been broken up for about three years now. The night that I convinced them to just go for it, I got to see the entire thing unfold with my own eyes. I still see her car at his house every time I drive by there at night. He is a lucky guy! He gets deep in her butt! The whole thing is a long story.
