World-class beauty Karina Hart is a natural in front of the camera. It's as if her sexuality blossomed when the camera was turned on. Karina can do the most-explicit poses and still look innocent and wholesome. "I think that sometimes in my private life, I can be very shy, and when the camera goes on, the real Karina comes out."

Karina is one of those girls who likes a man to be a challenge. "If he looks at me like he wants me and then he seems like he doesn't care," Slovakian girl-next-door Karina revealed. But there's always the possibility he might be gay.

"If I see a man from the back, I look at his ass first because I'm crazy about it. A man's ass is sexy to me. When it comes to satisfying myself, every time I get alone, it's my chance to get happy. I'm using my fingers and thinking about huge dicks."
