The Czech Republic is home to some awesome naturals: Zuzanna, Sophia, Lenka, Marketa, Ivana, and now new discovery Iva. Iva says her boobs started growing big at 13. "Now they are the right size, not too small, not too big. I am always keeping them in bras. I sometimes get bad and pull down my top to men at discos and swimming pools." Spoken like a cheeky little thing.
