Vida Guerra Best Ass on the Web?

One day Cuban hottie Vida Guerra decided to send in some amateur pictures of herself to FHM and men everywhere are still thankful for that decision. She has since appeared in magazines, movies, tv shows and talk shows. Below you will find some of her best images. Here's the question, who has the best butt, Vida or Keyra Agustina? If you don't know who Keyra is, I will be posting her soon, and Keyra was voted the best butt by Howard Stern last year.
