Catching My Step Sis Masturbating so She Fucked Me!

Last week I had just bought that new camera and I wanted to show my step sister. I was a bit surprised to find her totally naked masturbating while on the phone with her boyfriend. She seems pretty reserved generally but I guess shes got a naughty side too. I thought I should tell her mom what she's been up to but she didn't like that idea too much so I thought I could punish her and turn the situation around for me. She didn't seem stoked about the idea but she was even less happy about the idea of me telling her mom so I convinced her to blow me and one thing leading to another I got to give her a proper pounding before cumming all over her face. So you can say it all worked out perfectly. Lol
