I (28m) have just accepted a promotion at work that has me driving sometimes 2 hours a day. Well this morning on my way to one of our extremely remote locations something came over me. I was on a highway at 6 am and haven’t driven past anyone in at least 25 miles. My pants slowly became too uncomfortable with my dick slowly become harder. It was too much. I checked the glove box to make sure I still had some napkins, I did. I unbuckled my pants and undid my zipper. I adjusted my cock out of the hole in my boxers. The angle was a little awkward but there was a rush I can’t explain. I stroked with my right hand and kept the left on the wheel. I didn’t even last a minute. I cummed so much, I used the remaining 4 napkins to quickly clean up the mess. I loved it, but almost regret doing it. Now that I’ve done it once it will be hard to stop myself doing it more often in the future.
