With the exception of Mandy, I have had the most success with the Asian girls. They are never as advertised in their pics, but always young,, slim and in my experience very willing. I've always been made to feel comfortable and like a king by them.
I've read the bad reviews of the girls, I believe most of those stem from the fact that few (if any) Asian agency's use the girls real pics. If you can get by that though, the girls themselves are just fine.
