Miriam Gonzalez is a stunning big breasted Latina from New York (born 1977). She first appeared in Playboy in 2001 and did several more shoots for them after. You can also find Miriam at Pinup Files but for some reason she doesn't go topless there.
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
