First off no reviews ??

I can't do a google search on the images now, but I would guess I would find quite a few fakes

This agency has 42 smoking hot ladies on their webpage, really never seen that before  
(Well yes I have on scam webpages.)

Might want to stay away from them.  

Just my 2cents on the matter

Time to watch more march madness and staying away might make sense

Good points all.

Must have been using the small head ...

Grace is Annaissa http://topsecretescorts.co.uk/girl/annaissa/
Star (rainbow leggings) is Evanna http://www.agencybarracuda.co.uk/escort/evanna-651/
and so on down the list.  
.
Yellow Flag: SOMETIMES -- repeat, SOMETIMES -- Euro girls DO make legit trips Stateside and use a different name. YOU (OP) must check things carefully. If Star / Evanna is scheduled to be in both Boston AND London on the same day, THAT is a giant RED FLAG. There are probably more yellow and red flags than green flags, but you can do more searching on your own. You can ask supremegfe if the pics are real. They may tell you the pics aren't real but "an accurate representation of what she looks like."  Yeah ... and my Monopoly money is an accurate representation of real money. You can ask them, "Is Star really Evanna? Is she really in Boston?" and so on.

Or, you could stick with indies and agencies with better reviews and records of reliability.
