Sandy is not the girl's name. Whoever made the piguesex site at the time probably thought of the girl similar to the Brazilian singer Sandy, who at that time was at the era of photo montages with celebrities like that someone did with Britney, Christina Aguilera...
I took these photos through the Wayback Machine, unfortunately none of the front face.
From what I've seen from the photos taken from PigueSex, she has both nipples pierced, and three tattoos: one on her arm, a butterfly above her butt and a kanji with a design on the back of her shoulder.
On the first site you send I only got the thumbnails. In the second unfortunately the photos did not load for me.
But, thanks for your contribuition!
