I went into my sis' room to look for some condoms, and in there I found her horny slut best friend! She asks me why I'm looking for condoms and doesn't even believe that Magnums are the right size for my big cock. So naturally, I gotta prove this slut wrong ;) I eat her pussy and then put that Magnum on my massive cock and slide it into her tight pussy. But she is so horny that she wants that condom GONE! So she takes it off and I keep on pounding her tight wet pussy. I fuck her hard and rough in missionary, doggystyle, and cowgirl before I bust my fat load all over her chest and she sucks my cock clean. Then my sis comes back and catches us... whoops!
