On a really hot day, we’d been kayaking and decided it was time to pull up onto the riverbank and take our clothes off, have a fuck, then swim in the cool water. We found a nice sandy beach and pulled off. We got our clothes off, I lay down, my girlfriend mounted me and we started fucking. She couldn’t see up but I could. We knew there was a bridge nearby, but now I saw that on the bridge there was what looked like a scenic overlook about fifty metres horizontally from us and about a hundred metres above, with a group of hikers leaning over the rail and looking almost straight down at us. Many of them had binoculars, and they were aimed right at us. Even though they were above us, I figured the fifty or so horizontal metres was too far for them to throw anything at us, so I figured we were safe. After my girlfriend finished with a good hard orgasm, she lay down next to me and now for the first time, she also saw the people up there looking down at us.
