Those aren't fake tits. The videographer asks her if they're natural; she answers yes. At 17:45, you can tell they're real by how they're moving when she's getting fucked from behind. Damn nice pair; too bad they're on this pretty gal who has no interest in being there.
She's pretty and has a marvelous body but it appears she doesn't enjoy being a fuck slut. There's no joy in this clip for her. I hope she got paid well. This lucky actor gave her a good cum load on her pretty tits. Too bad she didn't enjoy the scene.
