Watch Kristen Stewart Read 'Fifty Shades Of Grey'

You might want to turn down the lights and lock the door before reading this next post, y'all. Why? Because we're about to hit you with the first ever episode of "Erotica": a steamy, sexy, never-before-seen After Hours that delivers the raw, uncut reactions of four stunned celebrities as MTV News' Josh Horowitz whips out his...

...copy of "Fifty Shades of Grey" and asks the cast of "Snow White and the Huntsman" to give their best dramatic readings from the text. Shocking!

The appearance of the book garnered a range of reactions, from horrified to curious to totally gung-ho. Least enthused about the fanfic-turned-bestseller? That would be Chris Hemsworth, who recoiled in horror and shouted, "I'm not even touching that!" from the get-go. (Although he did later peer between the covers and confess that what he saw made him "all hot and sweaty.")

But for the rest of the cast, it was all systems go: Sam Claflin's reading of the material was so smooth and sensual that we're pretty sure he should be tapped to voice the audiobook, and Charlize Theron was so excited about the whole thing that not only did she win for the world's best deadpan delivery of the words "oh-so-happy trail," she tried to remove some of Josh's clothes in the bargain. And even Kristen Stewart, who in all fairness would be fully entitled to feel freaked out by bondage erotica based on "The Twilight Saga," seemed mostly unruffled by the phenomenon and said she was eager to read it herself...although she added that there's a time and a place for such activities.

"I see people read this on airplanes, and I'm like, 'Ewwww,'" she said. Take that blanket off your lap, you freak!"
