I also hope that there is more. I found the same gallery in another site with almost all pics. Also in that one, we can see that Angel/Elvira has a lot of beauty marks on her chest. They were all taken off on the Just Teen Site gallery.

And the name of the photographer is on the top picture : Petr Kricek.
In the galleries of his website there is no girl called Elvira or Angel, but a few look like her. Here is the link.

There are 6 pages with 12 photos that can be enlarged. The girl called Mayka on bottom of 1st page look like her but we don't see her enough to be sure. Look at them, I am sure it will be easier for you to know if she is among them.
I hope we'll find more.
