Slipping dick into my stepaunt

I always fantasized about my stepaunt because she has a fat ass booty, I always imagine all the different ways that I would fuck her, I imagined her luscious lips sliding down the shaft of my cock. Well, one day she came to drop me off some groceries, And I was waiting for her. I was already so horny that I was stroking my dick, and I was gonna wait for her to see her reaction. Next thing you know she pulled off her pants, and I was so happy because I knew we were gonna fuck. Next thing you know I was fucking my stepaunt! This is a secret. We have to keep forever, but I hope I can keep fucking her.
