I travel a lot for work. When traveling more than a 100 miles, we are given a company car to drive. On one occation, I had to travel around 300 miles to inspect a site, and return on the same day.

On my way back, I got bored, and then tired, and then horny. To keep myself busy, I decided to put on joi porn on my cellphone.

After a while, I got so horny from the joi videos, I undid my pants, lower my zipper and got out by hard throbbing cock. I started to jerk off while driving. After around 10 min off wanking, I got close to cumming, and needed to decide if I was going to continue or stop.

I decided to continue and had to cum into a disposible coffee cup, to prevent cumming all over the stearing wheel and seat.

When I parked the company car in the parking lot, I dropped the coffee cup with my cum in, into a garbage bin, and went home. I did notice a small cum stain on the seatbelt when I got out of the car, but I am sure no one would norice.

Was one of the best wanks of my life.
