The girl you're looking for if you want dirty talk is Ronnie, 100%
She's white, takes great care of herself in terms of fitness and hygiene, thick & curvy in the best way, probably in her 30's as she's been around awhile, and has the most fantastic, filthiest dirty talk I've ever heard in my life (including porn etc)
The first time I saw her I thought I had an idea what to expect, but not really no. If you're into dirty talk, even if you didn't have a preference for Ronnie's appearance (and I can't see why you wouldn't) it would be worth paying her to sit on the edge of the bed and narrate while you fucked someone else. She's that good, and a quick search will confirm this is not YMMV, she's just the best when it comes to what you're looking for.
Hard part is finding her... she typically works out of agencies like Atlantis, Great Pharaoh, and Aqua, but I haven't seen or heard anything of her for while. I think her perb handle was most recently/is

This on too but it looks like it's been inactive for a bit.
