A girl I was dating several years back (and who I still see off and on) had a secret side to her personality. Just meeting her you'd think she was all apple pie and ice-cream... and real good girl. But, I discovered something else entirely. We were fooling around in her parent's living room one time, just groping and kissing like most teen-agers do, when I told her about a fantasy of mine. I suggested that she dress up in the shortest skirt she owned, a skimpy tube-top and heels... so that she had a dirty-girl look... and we'd drive down to the public park on the lake and have sex anywhere and everywhere possible. She loved the idea and rushed off to get ready.

I waited in the car for her, and when she stepped out of the house I nearly came in my pants. She looked dirty alright, but she couldn't shake the innocence and was the cutest looking slut of all time. We drove for about 10 minutes, the whole time with my right hand rubbing her bare thighs and her left hand stroking my cock. We walked quickly to the most secluded spot of the park and I sat down on a bench. She was facing me and lifted the hem or her skirt... she wasn't wearing panties. I wanted to fuck her so hard. She straddled me just then and sank down onto my cock. She bounced and swayed and lifted her top so that I could suck on her little nipples. We were loving every second of it, totally oblivious to the rest of the world. Just when I was about to cum I looked over her left shoulder to see a small group of young couples (three pairs of 15 year olds) watching her ride me from behind a row of short bushes. I smiled at them and lifted the back of my lover's skirt so that they could watch my cock sliding in and out. The girls all dropped their jaws while the guys just stared in disbelief. I must have cum for a good 40 seconds watching them enjoy the show... and my girl never knew what was going on behind her.

Hell, if she had known I probably would of have a hard time convincing her to do the same thing in three more parks that night. Then again, she might have loved the idea just as much as me.
