I had kept from masturbating for over a year and one morning woke up with a raging hard on. I reached down and pulled it out of my underwear and started to rub it very gently.
Pretty soon I could feel my orgasm coming on and I started to thrust against my hand. When I orgasmed, I shot all of the way up to my face, down my chest and then the last few spurts were just powerful enough that they puddled on my pubic hair.
I shaved from then on so that it is easier to clean up.
I grabbed an old pair of underwear and cleaned myself up.
