I have to say Ava Devine is the nasty one. I saw her in rough action with 3 guys. The rougher it got, the more she went for it. You should look at Missy Monroe . I saw her taking rough anal, rough face fuck and she was cummed deep in her throat. This is not so usual! Should you know of any other Model who can do it let me know.
I think Ava may be a bit more nasty, but I like Missy more!
