Personally I'd go for number 2 Delaila as IMO she looks very hot, horny, and sultry. Not keen on the look of number 1 Tiffany. And number 3 Britney has had 1 Positive, and 1 Negative Review to her name so far, so question marks on her for me.
So by process of elimination I would personally choose number 2 Delaila.
