Tara Radovic (1980) is from the Czech Republic but became famous by being a Penthouse Pet in Croatia. There's not really a lot of content of her online but Busty Cafe has several sets of her as Eva Svobodova. Not sure if she's still active (most her stuff is a few years old) as I read somewhere she's more interested in her regular career instead of modelling (what a shame!).
Viola Crush is a very top heavy young lady from Ukraine. She sure knows how to please booblovers as she takes her time to release her big boobs by slowly jiggling them out of her top and bra. Her cleavage prior to that is quite spectacular too :P
