I have met some wonderful ladies from countries across the globe and, individually, they provide their own unique, fantastic service.
However, I have to agree with the previous posters that Brazilian ladies are the most passionate, friendly, exotic and downright horny of them all. SabrinaLovely(alas departed) and Jasmin(thankfully staying for another while) are two of the most exquisite and delightful companions you are ever likely to meet.
I have not met Milla or PattyBaby but I have read their reviews so it's Brazil all the way for me.
