There are several, but this is the latest one.
It was at a public beach here in my town. We were tanning on top of one of the sand dunes. She was topless and I started playing around with her tits and a little after that she took out my dick and started playing with it.
On the dune next to us was another woman sitting, with another person hiding behind the bushes, it probably didn't know we didn't saw it (don't know if it was a her or a she). After enough fooling around she slipped her bikini to the side and I started fucking her from behind. There were quite a few people on the beach and the couple watching us and people walking on the path behind us.
I enjoyed it all the way to the end
