I just watched again, extremely horny and aroused, shooting out a load about the same as his. Shame on him for underestimating how much he was going to ejaculate, and not being ready for the mess. He should know better.
It would have been great to see him get the obstacle of his pants down the more aroused he got. I just shot out a load like this myself in the car in a parking lot with my pants down. Couldn't wait til I got home. Had my paper towel for no mess!
