I think you may have to go to Brazil directly. A lot of the chicks I have seen that make it to the UK are enhanced in some shape or form, not all as I have come across chicks that had natural tits and a bubble butt however, they are so rare. That's not even including GFE which will make your search even harder . Good luck.
This is a good point actually.
Although I do not look for a GFE experience, I tend to call it by the more neutral term
Customer Services Skills. It is one of the reasons why I stopped seeing Latin WGs.
I think you may well see the Bubble Butt, natural well before the GFE as you say
Horsa - Forget it mate!!
