Nikky Yann is a pretty young American model from the US. She has a non nude site as Alexis Naomi and since December 2015 models for Zishy.
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
