Jacking in Car

I was driving back to the city after a day of skiing, and I was super horny. I pushed my sweat pants down around my ankles, and I was sitting their in my turtleneck and jockstrap. I started rubbing my penis through the pouch, but needed more contact, so I pulled the pouch aside and jacked full on while driving. I put the jock back in place at the last second and exploded into it. It was awesome!
