Here are two pics of Exotica and Mercedez together...in my opinion Exotica has one of the best bodies in the world...she is thick enough that her DD's don't seem out of place...she is much more toned that Mercedez but they both are gorgeous
The most similar girl to her in terms of body and overall look is the Mexican centerfold, Nissa. She has a few links at Freeones and is lovely, although Mercedez is even more beautiful.
