I was getting ready to go play tennis when I noticed my daughter was gone and her boyfriend was still in her bed. I decided to go in and see what he was up to. We chatted a bit and I have been really wondering what he was working with after hearing them always having so much sex, so I started flirting with him. I asked him what was under the covers and he was nude. I started showing him little peeks at my pussy and ass as I had no panties on and a tiny skirt. It wasn't long and we were fucking and his fat cock made me cum so many times it was amazing. Now I know why she is so attached to him and why she is always screaming when they have sex.
