Well...technically this would qualify:
http://mumblez.org/nikki201101030288.CR2 (It's uncompressed at 20mb - you may need irfanviewer or a photo-editing program with RAW support).
After the flack that Nikki and her husband/photographer took for the censor boxes in the Gray Skirt & Socks shoot he posted a RAW file of Nikki's full frontal from the Ladder set - straight from his camera.
If you look (very) closely you will see that it is not Photoshopped. It's a crappy picture but you can just barely see the top of her clit-hood. She has a very low, very small pussy.
In other words, unless she goes spread eagle you aren't going to see much.
