I've always enjoyed reading the stories here and decided that I had to write about this experience.
This was my first time driving myself back to college. I attend an out-of-state university so I had a several hour drive ahead of me.
Initially I was driving on the main highway, but I had to make a stop along the way that required me to turn off onto a smaller highway. This road was much more winding and bumpy then the usual interstate so my car shook a fair amount. After a while I began to get used to the car's constant vibrations and tuned them out. However, it soon became apparent that the shaking was affecting my directly in my balls. It was subtle at first, but eventually the vibrations were giving me a full-fledged hard-on.
I tried to ignore it, hoping that it would subside, but the road refused to give me a break. At one point the tension building up in my jeans was too much for me to take, so I casually undid my fly a little, and reached in to lightly play with the tip of my cock. After a while I realized that I was going to need to have some sort of release sooner or later. I looked at the fuel meter and saw that I could still go a long way. 'Not soon enough,' I thought and quickly decided to pull over at the next town I passed.
I didn't want to stop for long so I figured that I was going to need some... 'supplies' to hurry things along at whatever appealing rest stop I would happen to see later on down the road. I pulled into a grocery store parkinglot and went inside the place to see if I could pick up some hand lotion and a copy of MAXIM or FHM, or any magazine with half-naked chicks in it. Of course, I picked up some other random items first to cover up what my real intentions were but only later discovered that they sold no such magazines. Just the usual People and TIME varieties. Well, I already had my basket filled up so I managed to at least get some lotion.
By this point my hard-on had subsided a bit but getting back onto the road brought it back. I rubbed myself through me jeans and decided that I needed to take action soon before I burst. I pulled over the next opportunity I had to get gas and only ended up discovering that this store didn't sell the kind of magazines I sought either. I wasn't about to jerk off in that gas station rest room so I just filled up and got back on the road. I decided at this point to just try and wait it out. No luck.
While the road eventually improved, my situation didn't. I probably would have been driving the whole way at attention if I hadn't realized how few cars were on the road with me. I've read about people masturbating while driving and the thought quickly interested me. I did a quick look around, set the cruise control to a safe speed, and un-zipped my fly.
I began by taking my cock out. I didn't stroke it much at first, I was a little nervous at first, but I eventually became comfortable with it out. I added a dab of lotion and slowly began to stroke. It felt so good at this point. I leaned back a little and bit my lower lip. It was at this point that I noticed a car coming up from behind. I instantly chickened out and put myself away. I let them pass but before I could get back to work I saw a sign indicating that I was going to merge back with the regular interstate very soon. I decided that I was going to have to be bold to make this work. I pulled over to the side of the road and removed my boxers. This way I would be less restrained in my stroking and it would be easier to take out and put away, should a car pass. I put my jeans and shoes back on and prepared to merge.
At first I was nervous, but quickly overcame it. I pulled out my now throbbing cock, set the cruise control to a safe speed, and did a quick look around. I put a big load of lotion onto the tip and began to stroke and spread it around. I was in light state of ecstasy as I leaned back and played with myself while driving down the road. A car was coming up a ways behind me and I almost chickened out again. However, my horniness was was too strong and I just continued stroking while I watched it approached. They zipped by and before I knew it I was stroking harder and faster. Being that close to unsuspecting drivers was giving me a rush. I held a reasonable distance behind them and began to stroke ever faster. I added a little more lotion and at this point I was at the point of no return. I HAD to cum. I pounded my fist up and down and slowly began to lift my ass off the seat. I arched my back a little as I slowly moaned, 'oh fuuuuuuuck yeah. oh baby fuuuuuuuck.' I leaned back and bit my lower lip as I beat off faster and faster. 'OH FUUUUUUUCK!' I moaned loudly as pushed myself over the edge and shot streams of cum all over the driver's seat. My orgasm easily lasted a good 20 sec and it's a wonder how I managed to stay on the road!
After a the feeling subsided I looked and saw that the seat was a mess. I cleaned it up as best that I could until I had another chance to stop. On a whim, I made sure to grab additional cleaning supplies before I left which ended up being a good thing because I repeated the act twice more before reaching my destination.
I'm positive that no one saw me, but the idea of other people being so close around was a huge turn on. One thing is for sure though, it made the drive go by a lot faster!
