I won't speak for any girl in particular or try and get your hopes up, but your bigger question is if they turn tricks at all. If they do, you're a bit loco in terms of pay scale. I know for a fact there are some very well known pornstars active today, where £1000 (I believe about $1600 in your blood money) gets you an hour in their company where you can fuck them any which way you like, stick your uncovered cock in their mouth and cum in it as many times as you like/can in the hour. One I know for sure will throw anal in at no extra charge.
Don't do it though. If you find one of your favourite pornstars escorts, sure you'll meet them, fuck their brains out (or at least your own) and have an amazing time leaving you with memories you can wank over until the day your knob dries up and falls off. But your soul will burn forever in the fires of eternal damnation, and that's more important.
