When I was in the Air Force I worked with a guy who admitted to being fooled in Italy. He and another guy picked up two hot chicks at a bar. They were making out when he reached into ‘her’ pants and found a surprise.
He was so very sorry he told us that story.
Should have done the "Sheila Test."
You always, ALWAYS! check for the ‘package’ or the Adam’s Apple the first chance you get. Especially before you get to the swappin’ spit stage.
