Wife Seeks Pleasure on Cheating Husband

I met this woman at a bar a couple weekends back. She was mad a her husband for cheating on her. We had a few drinks and talked for a while. I convinced her to go to my place after closing for a few more drinks. I proposed and idea to her. I suggested we make a video of me screwing her to give to her husband. She thought it was hilarious and agreed however she said she was not using birth control and didn't want to get pregnant so I could only screw her anally. I said no problem and set up the camera.
