Young girl shares naked photos with her boyfriend and has sex with me

The other day, my girlfriend shared some of her naked photos with me and I thought it would be a good idea to show them to my friend. As soon as he saw them, he got really excited and asked me if I could come over to his place. When I got there, he was already waiting for me and he was really turned on by the pictures. He asked me to bring the girl over so he could have a taste of her. I called her and she agreed to come over. When she got there, she was really nervous at first, but then she started to get turned on by the way he was looking at her. She decided to have sex with him and I got to watch the whole thing. It was an amazing sight to see her getting fucked by another guy while I was just watching.
