Hmm, I'm not too sure
There's various agencies and independents
Judging from all the girls I've heard about and read reviews on, may be best to just say screw it and see Britney from forever lol
You may or may not get PSE, maybe PSE-lite, but I wouldn't count on it
She also has more of a big round ass I think instead of big titties?

Easy to book though from what it seems and I haven't read anyone being super pissed off or anything
So you could probably walk away with a mediocre experience as the worst case scenario
