between 10 and 12 one day about 5 or 6 years ago, I just couldn't stop....It's was my first time looking at internet porn with high speed connection, I had just gotten rid of the old 56k and the porn was coming soooo fast with every click. My dick was literally sore and by the last jerking I came, and felt every sensation that you are supposed to but absolutely no jizz came out...kinda scared me, although I did notice my load was getting smaller with every cum, but I didn't expect not to get a single drop on that last one
