One night my GF and I were talking about sex stuff and she said a friend of hers had a MMF threesome and said it was pretty hot. I told her my best friend Matt would be happy to join us. She wanted to but didn't want to look like a slut. We cooked up a plan where she and I would have some drinks, start getting into sex and Matt would "just show up" and end up joining us. It worked great and we all enjoyed it (she came like 8 times). Matt came over her tits and I shot my load over her pussy.
