Nude Celebs: Natasha O'Brian - Penetration Angst (also known as just Angst in the U.S.) is the incredible tale of Helen (underground sensation Fiona Horsey) a young woman who inexplicably devours every man she has sex with... Literally. Trouble is she doesn't want to kill them, but it appears that a certain, southern body part has a mind of its own. Burdened with this seemingly insatiable problem, Helen finds herself turning to the streets in order to satisfy its demands though things get even more complicated when she eventually falls in love. Strange bizarre and oozing with black humor Penetration Angst is a mind-blowing journey into the darkest recesses of madness.

Also starring Beth Steel and Amy Steel as Siamese Twins, Jaye Macauley as a conniving stripper, and Natasha O'Brian as one of the stripper's co-workers.
