Sex in a weird place.

So I'd been seeing this friend for a while who introduced me to some guy. We had been going out for a while and I was having a great time. But then suddenly I saw him at the train station and he had pansted me. It was so weird because suddenly I was on top of him and we were having sex. I had no clue what was happening at the time. But oh holy hell it was one big highlight in my life story. Someone had even said ew. Not sure what happened but I nearly fainted.
