The strangest sex I had was on the side of a bridge in Boston during the day with people passing by. The girl was really hot and she got this look in her eyes that said, "let's take it to the next level." But the strangest stranger sex was with this girl on the train. I was working on my computer. She asked me to move to the seat next to her. One thing led to another and I started massaging her. She went to the restroom came back and whispered in my ear that she had removed her underwear. It was great after that. People on the train were staring at us when we got to her stop and she got off. I was the envy of every man on that train.
