Fucked with my sister's husband

I was supposed to check on my sister's flat. I thought no one was at home, but when I got to the flat, her husband was in bed. I'd always thought he was really hot and apparently he thought I was too. We seized the opportunity and did it in her bed. I sucked his cock until it was nice and hard and rode him off. He fucked me really hard and squirted his bag cream into my face and mouth. That won't have been the last time I fucked my sister's husband! The guy was just awesome.
