My sister always made me horny, she was home that day and I decided that maybe I could fuck her. As soon as my wife left, I took advantage and took her to the room to do it to her, she also wanted to. She had a curvaceous body, nice tits and nice buttocks, she was a total whore. I put it into her and I did it to her like the slut she was, how nice to fuck that little pussy. In the end I ended up inside her, I poured all my cum into her. I heard my wife and I hid, but when she entered she found her friend naked from her and full of cum. She told her not to worry, she knew she had leftovers we had been fucking.
