I love long drives!
I used to do a lot more traveling when I was in college. I am an early riser and preferred to hit the road as early in the morning as possible. I would quickly become alone and bored as I thought about the long hours of driving ahead of me. I usually wore jeans and would sit so I could open my legs enough to slowly and softly rub myself through my jeans. Of course, it was always important to set the cruise control.
After tingling for a while, I would pull off the road and I would unzip my jeans and push my hand between the layer of denim and my panties. I would rub myself slowly and then faster and faster, until I came, shivering and shaking, watching other cars going passed. It was one of the best feelings.
One of the excitements would be when trucks would pull up behind me. I always wondered if they could see into the car and what I was doing.
