Daria is a busty Russian girl who lives in Austria. She's best known for her rock hard nipples who are surrounded by very prominent glands of Montgomery (I had to look up that one as well!). You can find her at MC Nudes, Sublime Boobs and other sites.
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
