I went out to the national park with my wife early one morning. We were swimming in the lake before sunrise and making out under the stars. My hands wandered. One the thing led to another, and I couldn't help myself. I pulled her bikini bottom to the side and we fucked standing from behind while half under water. Before I could cum I saw morning joggers on the opposite cliff in the distance, so I pulled out and we pretended nothing happened. I don't know if anyone saw us.
