Tusia is what she's called at AVErotica. She has one movie (and no pics) at the site averotica.com, but it's a doozy! I'm a huge fan of Tusia/Natasha and I purchased a membership just to get the movie. In the movie she washes body-makeup off of Katya, then they do a little caressing, a little snuggling, and then a nice long deep kiss. WOWWWEEE! Very hot.
Here's a teaser pic.
And here's a little blurb (supposedly written by Anton Volkov) that says how he "met" her.
I really adore her; I wish she weren't so hard to find.
