Link to her reviews...
disclaimer: this is in no way admission that i have met her and this post below is all just fantasy fiction. 
she is the real deal. i have met her more than once the same month, as she was that good. she provides just about everything on the menu. she took me like a champ. i highly recommend her.

It appears she has gone independent. Here is her new website. The price has gone up but it is well worth it. She looks amazing in her pictures. I cant wait to schedule a date with her
