I though she was retired, but take a look a this:
first-nude.com -- They have hotlinking disabled so you'll have to manually paste in the URL, but there is a "update" on the first page that seems to be our Natasha with another Woman -- Natasha is at her breast and is looking out to the camera.
I looked through the tour, and I could not see here trademark mole, but I'd bet it is her. In these pictures she looks more like she did towards what was the "end" of her career, where she put on some weight (*Note, I'm not saying she got fat -- she was just soo skinny in the earliest pictures.)
Anyone seen these before? Or does anyone know where the full set can be found?
