I had a friend of a friend who was throwing a bachelor party for his buddy and he could only do it a few nights before the wedding. He wanted to do something special for him without it getting back to the guy's bachelorette and offered me to the groom for a one night stand.  I had already sucked off all 6 guys at the party when I took the groom into an adjoining bedroom. Since his fiancé  always made him use a condom when they fucked I made sure he had a condom for me also, but since I was feeling especially naughty, I easily convinced him to give it to me bare instead. By the time we finished, his new wife would always be the second woman he dumped a load into.
