My wife told me her most fucked up sexual stories one night when we were drinking. She had a one night stand with a black midget with a huge dick because she felt bad that he caught her giggling at him in a bar. He confronted her, she felt bad (and was drunk) and the next day she was doing the walk of shame from his place. She said that fucking him was creepy at first but he had a huge dick and he could fuck her doggie while standing and she said it was amazing.

She also once gave head to a dude dressed as Abraham Lincoln at a Halloween party.

That's about it.
