The chemistry is for real in this consistently entertaining experiment by sex educator-writer Tristan Taormino to get under the skin of skin flick performers. The cameras show the "how," but she's also after the "why."

Seven porn stars stay in one house for 36 hours and are filmed non-stop, fucking and talking, with no script and no prompting. They have rap sessions with Taormino and each other about themselves, the industry, sex in general. There is a vibe of openness and trust.

Marie Luv, Mika Tan and Taryn Thomas are among the industry's strongest performers. Dana De Armond is a relative newcomer from fetish movies and the Internet. Jack Lawrence, Kurt Lockwood and Mr. Marcus hail from the non-misogynist pasture of the stud farm. All are articulate and charming.

When they start to fuck, everyone changes partners – constantly. Each star has a "perv cam" with which they can shoot the others.

There's some intrigue about getting Marie, who rarely does girl-girl scenes, to "experience the pleasure of a woman." She does but still prefers cock, as well as Jack's considerable cunnilingual skills.

Mika shows her prowess with a strap-on by convincing Kurt to take it in his ass as he fucks Taryn – all three connect in the spoon position, a novel idea, sensually executed.

The performers reveal themselves in odd ways. "I don't think I've ever been so happy," Dana burbles as she bounces on Mr. Marcus? dick during an orgy. It's funny, touching and as real as it gets.
