Recently, Kristen Stewart has been making headlines for her risqué performance in this year's Walter Salles-directed Jack Kerouac adaptation, On the Road. In the movie, Stewart plays a sexually uninhibited 16-year-old free spirit named Marylou. Marylou, along with her husband Dean (Hedlund), have a couple of threesomes with Sal Paradise (Riley), a young writer whom the couple wind up on a road trip with. First, Marylou simultaneously pleasures both of them while all three strip down in their car, and second, the trio wind up in bed together at one of their stops across the country.
