This afternoon on my 45 minute commute home I was feeling the need for some relief. I really like masturbating with lube, but none was available. I pulled into a convenience store near the interstate, went in bought a pop, looked around for something to use for lube, found Vaseline lip therapy, made the purchase and was on the road.
After a couple of miles I undone my pants, pulled them and my underwear down to my ankles. I was still limp, I just drove a few miles without touching my dick, it was then pretty much grown from the excitement of people driving by and seeing me with my pants down. I went ahead and filled my right palm with the Vaseline lip therapy, rubbed it around and began slowly stroking my cock, which was already dripping of pre cum. I just drove and stroked, watching the looks on peoples faces as they drove past.
After driving and stroking about 20 mins I was so ready to shoot my load. I reclined the seat further back and started beating faster. A semi truck pulled up to the right lane, I looked up to his window, sure enough, he was looking right in. He kept pace next to my car, even honked his horn 3 times. I was preoccupied by putting on a little show for the trucker, I hadn't noticed this young guy on a motorcycle had pulled up and was driving right next to me on the left. Once realizing this, I had to pace myself. We all drove like this for a good 10 miles as they were both watching, I arched my back and shot my cum all over the car, and drove off. It was incredible, very intense, I'm not sure I will share this experience with the girlfriend though.
