I see she is also listed on  the site  http://www.allnaturalescorts.com/escorts/escorts/New-York-Escorts/shawna-.html
That agency has only 2 reviews.  One good and one awful.
They list Shawna as natural with no implants (what a joke) and GFE.

Which lends an air of credence.  Still, $1K is awfully high for a TOFFT...Caveat Emptor without any reviews.  

As for the rack being natural...  Yeah, sure, right...

Yeah I saw the $1000 rate. Not sure that lends any credence to her, but the girl if real is totally stunning.  Npt Google or Tineye hits other than that agency.
