(After a long search, I think she hasn't got a thread here yet...)
http://thenude.eu/Kristina_G_2646.htm
(she's the one with dark/black hair)
Any info on her? Has she done only those 2 sets? Could there be more of her on other sites? Is there any free gallery of her?
Any help will be appreciated, TIA!
