Poor Nikki seems to get a lot of grief over her looks, including some fairly nasty comments in this thread. Personally I reckon she's fantastic looking, with the sort of lips that could suck the skin off a sausage and a perfect "Grrrr!" look for those moments when she wants to give the impression that her partner is just that little bit too big.
She's also, in my opinion, really dirty looking, and that's no bad thing!
If I were to have one tiny complaint about Ms Delano, it's that she has a habit of taking her heels off as soon as a scene or shoot gets a little messy. For this shoe fetishist it's quite noticeable. I wonder if she doesn't want to ruin her best shoes with a spattering of jizz...
Here's a nice set of Ms Delano in a pink bikini (and heels...)
