As I don't know if this forum allows embedded video I put here a couple of links.

They are from Kagney Linn Carter.

The first one in youtube, she is smoking after an scene and her eyes, her voice and her attitude reflects the emptiness inside her.

The second one is from a Rocco Siffredi film, she is having some issues and in the second part she really has that "Dead Inside" looks.

This video is a bit shitty due to the spam but deserves the viewing.
