What was your craziest sex you've had?

One night me and my girlfriend were walking home from a concert. and so i'm trying to get laid at this point. so i pull her away from the sidewalk and next to a fence covered by trees. and i start kiss her up and down her neck while i slowly run my hand up and down her waist. i pull her in so she can feel how hard i was. but i knew we couldn't attempt any thing there so we continue on further down the road looking for a spot we could have sex. we ended up on a hill with lots of brush and trees that hung over a high way. so the trees would slant as it was covering our shame. i started out by fingering her a little to get her riled up and to get the juices flowing. we moved to a cowboy position and she road my cock like she was trying to win a race. and as the cars drove by i could only think about the ecstasy and the thrill of being in public. at this point i'm thrusting with so much power that i'm sliding down the hill. and readjusting is giving me more time to stall my climax. but i cant hold it in any more i grab her arms and i pull her down and i cum in side her with so much force. and all this experimenting has gave us this lust that we go again. but this time she wants me to take her from the back. and at this position i can thrust even harder. the sound of our skin hitting each other is even more arousing. it doesn't take long before we cum again. at this point she can barley fill her legs but we manage to get back home and have the best sleep we've ever had.
