With MET-Art she is called Natasha P.. Do believe she never appeared solo with MET, but only together with Katya T. Series "Nireas" (your gallery), and another one called "Eau Pure" both by Volkov:

She also appeared as Tusia with Domai. Don't have a link for a gallery - only a few sample pics. Think she appeared only once with Domai by same photographer Volkov.
