Years ago I frequented one particular bookstore. It was out of my town, so "frequent" meant every couple of weeks or so. There was this bog goofy clerk there most times. I love sucking cocks with no idea of who they were attached to. I did recognize one particular fine cock, though. I sucked it at least 4 times over a couple of months. The next time I entered the store, the same clerk looked up and gave me a huge smile. He said "Hey! How are you doing buddy?" I chatted a bit with him while getting my $10 changed to dollar bills, then went to the booths in the back. It was only about a 2 minute wait until that familiar cock slid through the gloryhole. That's when I finally figured out it was the clerk I had been blowing. His cum was delicious!
