I went and saw Ronnie at Great Pharaoh today, and I thought of your 411 request which I read a couple days ago.
If it's a filthy mouth you're into, you NEED to go see Ronnie. You don't even need to bring it up with her first, you can just start doing your thing, and if you don't, she will anyways. I've seen probably around 100 civilian girls and the same number again of escorts, and I've NEVER met anyone as dirty as her, not even close. A bit of dirty talk during the deed can sometimes be fun, it's not a fetish for me by any means, but the shit that came out of this girl's mouth! Degradation well definitely not be a problem with her. I don't think ANYTHING would be a problem with her.
Well, there ya go! Have fun
