Wendy Combattente became well known through candid pics of her showing her huge cleavage. Later she did shoots for Sport4Brooks and eventually opened a personal website in 2010 called Wendy4. She claims to be 'all natural' but since she does bikini modelling only there's no definite proof.
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
