Sneaking a peek at work and my officemate might get back any minute...
Very, very, very tough decision. Two absolutely stunning brunettes, both with very nice breasts (Catalina's new ones look even better than her old ones), both with wonderful hair, both with stunning faces, both oozing sex appeal. On top of that, from what I've seen, both of them are very sweet, genuine, down-to-earth women who are open and friendly with their fans.
So how to break the tie? In the end, the only thing I can think of is that Catalina posts here and Nikki doesn't. So with apologies to BigNikkiFan, and major major regrets to the gorgeous Nikki Nova, I'm going with the homegirl.
