I agree "best" is a silly term here, "top" is only slightly less silly. When I read these titles I always insert the term "in your opinion" in my own mind. While I wish I had more first hand knowledge of a "broader" sampling, this sort of thread is an ideal place for ladies to post more photos of their lovely eyes and lips.
This one is from a few years ago, and meant more as an artistic expression rather than a pix for ads, she wanted a very dark background, since she had her hair pulled back the final result reminds me of a mocha version of the chick in the first Star Trek movie (although Pleasure does really have hair!). But still, those eyes and those lips are as they are in real life, totally awesome!
So come on ladies, give us a peek at those peepers!
