This is nude/glamour stuff and not porn as such, but since there's nudity and several threads about skinny girls in here I guess it goes. Now I like skinny chicks, Nikky Blond type pornstars and models, but this one is WAY beyond what I fancy. I came across a video with a girl who's called Irina (russian), who's weight is next to nothiing and who's website is very fittingly www.absoluteskinny.com.
She's a kind of nude contortionist artist. What baffles me is that although she looks like having an advanced case of anorexia nevrosa, there are small but visible tits. In the video she also appeared quite energetic and her face doesn't look all fatigued like anorexic chicks. I'm guessing she has some sort of physical condition.
Anyway, I was put off, but for the extreme skinny lovers it might be worth checking out.
