I work at a restaurant, and I was almost through cleaning up when I saw Diana clocking out. I didn't want to ride the bus home, so I asked her if she'd give me a ride. Also, any opportunity to be with Diana I'd take, she was hot. I'd used her as jerk-off material many times, and seeing as she had on a cute little skirt that showed off her legs as well as her ass, I could barely suppress my erection when we got in the car.
About halfway to my house, it hit me. I wanted to fuck Diana like I'd never wanted anything else in my life. My dick was hard and I was forming a tent, but she never looked over. We made small talk, it was excruciating. I wanted to do something, but I was sure I'd get slapped if I muttered one word of what I was thinking.
I couldn't control my actions any more, I undid my pants and pulled my cock out. She didn't notice until I started stroking it, but when she did she gasped in horror and almost ran us off the road. I thought she would slap me or at least say something to me about it, but to my surprise, after the initial shock, she just kept on driving. So I just kept on stroking my dick. I noticed her glance over every once in a while, just a quick glance, to see if I was still doing it.
About 5 minutes later, her right hand drifted down under her skirt, and I could see her middle finger slowly moving, out of the corner of my eye. That's when I noticed we weren't heading toward my house any more, we were going somewhere else, but I didn't know where. About ten minutes later the car was starting to get hot with sexual energy, and we hadn't even spoken a word since I exposed myself.
We pulled into a kind of wooded area and there was no one else around. Diana was really getting into herself, she had her panties pulled to the side and two fingers going hard and fast, and she was starting to breathe heavily. I reached over and put my hand on hers, pulling it up and out of her. As I did this, I ever so softly traced the length of her lips with my index finger, and she clenched up her body and shuddered.
