Xerex -

That lady goes by Katya AB, and you're right, she's a "wow". She has a thread at http://peachyforum.com/forums/thread/271631.aspx 

Here's a link to a preview set of a marvelous MetArt set called Avexian, with her and Alena:

I also happened to see the covers of 3 other sets with those two same ladies, but no preview sets or working links:

Thamis:  http://img24.imagevenue.com/view.php?image=31601_logo_122_547lo.jpg

Silence:  http://img25.imagevenue.com/view.php?image=31771_logo_122_555lo.jpg

And, on the subject of duets, here's another cover that looks very promising indeed, called "Secret Friends", with Lesya B and Ira B:

In case that's the one, her thread is at:  http://peachyforum.com/forums/thread/294590.aspx  Also, send me a PM, and I can help you find more.

If that's NOT her, then tunaman, try to give us a better description than just "tiny". Does that mean really short? Skinny? Flat-chested? All of those? And, do you recall any poses, clothes, etc? R-rated only, or X-rated too? Tattoos, etc?
