Fantasy Role Play Outdoors

My gorgeous girlfriend recently told me of a fantasy she has of meeting up with somebody purely for a quick fuck. So I messaged her as though she had put her contact details on a site and we sent each other photos and arranged a meeting place. I scouted for an outdoor venue and we met on a rainy Thursday around 6pm. She wore a short skirt with crotchless knickers and a white top with no bra. As it was raining the top became see through. We walked straight to a park and an enclosed area but only enclosed from most angles, so anybody walking past would see us. I put on a condom and she straddled against a tree and I entered her. After a while I lay down and she took off my condom and sat on me. While fucking I pulled her top down to expose her amazing tits. Anybody could have seen us but we carried on until I cum inside her. I then took a few photos of her topless before we left the park and she went home. It was absolutely amazing and I hope we were seen by dog walkers and joggers. We are now carrying on the fantasy and meeting in different places for a quick fuck.
