The film adaptation of Jack Kerouac’s famous 1957 beat generation novel “On the Road” hits theaters on Dec. 21, and audiences will be treated to a variety of sex scenes involving Kristen Stewart’s 15 year-old-character Marylou.
“Kristen Stewart goes to bed with two men at the same time, gives both of them simultaneous hand jobs in the front seat of a car and performs oral sex on one of them while he's driving said car. She also appears topless twice, once just minutes into the movie, and spends much of the rest of her time doing drugs and robbing people,” Huffington Post’s Michael Hogan wrote in September. 
Kerouac’s Marylou meets and marries “On the Road’s” central character Dean Moriarty at the age of 15, and The Denver Post reported that “On the Road” is a semi autobiographical tale of Kerouac’s life.
“Dean was based on the infamous beat-generation figure Neal Cassady, Sal on Kerouac, himself, and Marylou on LuAnne Henderson, who married Cassady in 1945 at age 15,” Rob Lowman reported .
But for “decency’s” sake (if you can even call it that) the film version of Marylou is aged to 16.
Kristen Stewart committed to the role of Marylou at the young age of 17 with full knowledge of all the film’s sexuality and nudity.
"I should have definitely been older than 17 while playing this part, absolutely," she said. "[My performance] would have been done very differently if I was younger. I wouldn't have played the part, obviously," Stewart told MTV 
While dirty dancing “terrified” Stewart
she brushed her topless scenes off as “no big deal. ” “It didn't bother me.
You can do no wrong with [director Walter Salles]. He puts so much inside of
you,” Stewart said.
The self-destructive character of Dean Moriarty even exhibits tendencies of pedophilia in the book version of “On the Road,” and boasts he started having sex at age nine.
On page 139 of “On the Road” Dean lusts after Marylou while wondering what she would have been like at the age of nine.
“I tell you it’s true, I started at nine, with a girl called Milly Mayfair in back of Rod’s garage on Grant Street— same street Carlo lived on in Denver. That’s when my father was still working at the smithy’s a bit. I remember my aunt yelling out the window, ‘What are you doing down there in back of the garage?’ Oh honey Marylou, if I’d only known you then! Wow! How sweet you musta been at nine.” He tittered maniacally; he stuck his finger in her mouth and licked it; he took her hand and rubbed it over himself. She just sat there, smiling serenely.”
Needless to say, liberal critics are falling over themselves to praise the film’s gritty content and “powerful” message.
“Stewart's Marylou is pure Id: she steals what she needs and she screws who she wants, when she wants. And Stewart -- who, lest we forget, is only 22 -- is so convincing in the role that I can't help feeling glad that she now has the chance to stop playing house with Robert Pattinson and truly explore the world,” raved HuffPo’s Hogan. 
The Hollywood Reporter found “On the Road” to be a “beautiful and respectful” adaptation of Kerouac’s novel, which isn’t really beautiful and doesn’t respect much of anything at all.
“But it’s the group adventures that count the most, and Salles has captured some of them quite evocatively,” Todd McCarthy reported.  “A wild New Year’s Eve party where Dean and Marylou dance in a sexy frenzy; a calm and weird stay at the Louisiana home of the William Burroughs character, Old Bull Lee (Viggo Mortensen, very fine); another sexy scene in which Marylou simultaneously pleasures Dean and Sal (out of camera range) as they all ride naked in the front seat of their car; Dean’s escape from domesticity with Camille as he joins Sal at a club to see Slim Gaillard, and a wild sojourn south of the border for mind-blowing weed and Mexican whores.”
Mexican whores? That is “powerful.”
