I'm not very active in my actual sex life, but masturbation is an everyday thing for me.
I go to college in a different town than I actually live in, so I have to drive to my classes every day I have them. It get's kind of stressful with college and work and the drive between town's because of my unreliable transportation. It get's lonely on the drive sometimes, and with my limited free time I have been limited in my 'personal' time, even in the shower.
A couple of times I have just been pleasing myself on the road simply because it's easier, and pretty exciting. The last time was before the Christmas break, and with the stress of finals I had some really pent up tensions.
Because it's usually late when I drive home it's dark so I don't have to worry about being caught too much. It started off like usual, just some grabbing, rearranging, and holding. But not even half way home I was just too hard to stop. My six-inch cock was being restrained by my pants and started to hurt from being under pressure. I unzipped and unbuttoned and pulled my cock out from the flaps of my tighty whitey's. Being in my car I had to use spit as lube because that's all I really have, and I just began with rubbing the head of my swollen cock. Eventually I just couldn't help it and began to pump myself vigorously.
Feeling the end coming I slowed down and just tried to enjoy it as much as I could. Being so close to cumming I couldn't turn back and just slowly brought myself to the point and shot four strings of cum onto my dashboard, steering wheel, and windshield, and had my hand soaked with cum. When I started getting into town I just started to clean up using whatever I could find around my car. The cum dried up on my steering wheel and dash though, and I'm really lazy about cleaning. Good thing everyone just thinks it's Cola I spilt on my dash. So, whenever you're driving on the highway at night, you might be able to imagine what some guys might be doing on the road.
