DD is a wonderful measurement for a pair of breasts, especially if those breasts are all natural and if the girl they belong to is quite slender. That's the case with Katerina Konec. The Czech pornstar has splendidly large natural breasts and a fairly slim waist, a combination that will blow your mind. She joined the adult business in 2001 just before her 20th birthday and she came out of the gate swinging with tons of scenes in the first few years. She has since slowed down but this busty dream of a girl continues to show it off and make her big natural tits a draw.
