I have seen and reviewed her! I didn't have full sex, but did kissing and oral.
She is probably your best bet for a "dominatrix who has sex". Yes, she is expensive, but she is attractive and very good at what she does.
How hardcore do you want the domination side to be? If it's only mild stuff then there are probably some regular prossies around who could turn their hand to a bit of spanking, face-sitting, strap-on and so on.
But if you want it a bit harder, then Miss Luxx does have all the kit and a sturdy bed or St. Andrews cross to restrain you to.
