I have a couple I know. It's a stepmom with a great ass and her horny stepson. They often experiment in a public park. It turns them on a lot. And this is the picture that came to my mind. Stepmother sitting in the park allows her stepson to pee on her thick sexy legs. The stepmother was just sitting on a bench, her sexy legs were bare. The stepson came up, unzipped the fly of his jeans and took out his cock and gave out a great big jet of warm urine on his stepmother's legs and feet. Then he hid his cock in his jeans and left. I was very excited and pleased with what I saw. And I managed to capture it on the camera of my phone.
