Sometimes things happen real fast.
I was taking a leak outside my bud's house on the nite of my 18th birthday. His dad came out to join me. We urinated for a while because we drank a lot of beverages.
He looked at my cock and then his to compare sizes and said, out of the blue, that he needed an orgasm real quick. I got a hardon and he already had one.
We reached down and we masturbated each other then jacked off each other. It was over in seconds it seemed.
We zipped up and gave each other the high five sign. I kinda think we will be jacking off each other again, because I will be working for his construction company for three months until summer school starts.
