Does anyone know of any Russian or Eastern European providers in the
Boston area?  (Ideally a petite woman with smaller breasts.)

I haven't had much luck with the "Search Escort" feature...

Thanks in advance for any pointers!

No, you won't find any in these parts, but your posting made me laugh.....  I've always believed that Eastern European women are the most beautiful in the world, the more petite ones especially  (Ah, those round little faces.)  The prettiest women I have ever seen were in the Ukraine, Hungary and Slovakia. I might have written that posting myself, except I didn't because I know it's essentially a lost cause.  For best results, get yourself a plane ticket to Kiev.

You might try Lara Nichols.
She is based in NYC, but tours to Boston
every now and then.
She hails from Slovakia
(or is it Slovenia, I never can remember)
Expensive, but worth it, IMHO.
