This is the motherlode...i have found hundreds and hundreds of great topless Kazantip photos here that I've never seen anywhere else.
You do have to register to see and save the full-size photos, which takes a little guesswork as the site is mostly in Russian, but if I could figure it out, anyone can.
Not every subfolder has topless/nude stuff, but certain ones are nearly ALL that.
Tip: when in a subfolder, use the sort phrase: категории. It's a button at the top of each page. It sorts each folder by "most viewed photo", which in every case means "topless photos".
You could easily spend hours here. 2005 & 2006 have the most topless/nude photos:

Here's a good subfolder right off the bat:
