Persuaded my girlfriend to have her first threesome

I had a sneaky look at her history on the PC and found something very interesting. She likes to watch dirty videos and loves threesomes. I already knew that she had never had a threesome, so I thought I could just surprise her with it. And she was visibly surprised. At first I thought she would chicken out when he came in and had a hard-on as soon as he saw us, but quite the opposite, it made her super hot and me too. After we made out, she stuck her butt out as if she was saying, come fuck me! :-D That was a really hot threesome, I really liked the way she enjoyed it and of course I was fucked really hard by his hot cock. And then he fucked our tight cunts alternately every second and then sprayed my mouth full, which of course I then shared with her.
