Kristen Stewart defends topless threesome scene in new flick

"In the film ‘On The Road,' Kristen Stewart engages in a threesome and masturbates two male characters," Dan Gainor of the Culture and Media Institute told Radar Online.

"How will parents who took their daughters to see the ‘Twilight' movies explain this? It is irresponsible of Stewart and manipulative of Hollywood bosses," Gainor said.

Despite Gainor's complaint, Stewart doesn't seem too concerned. At a press conference for the film, she talked about the film's more sexual scenes.

In the movie, based on Jack Kerouac's 1957 book, Stewart plays Luanne Henderson, the 16-year-old wife of Kerouac's friend Neal Cassasdy. She is seen shown topless in a backseat with actors Sam Riley, who plays Kerouac, and Garrett Hedlund, who plays Cassady.

"I wanted to do [the scene]. I love pushing. I love scaring myself," the New York Post quoted Stewart as saying.

"I've always wanted to get as close to an experience as I could," she added.

While Stewart may be 22 now, she said that she was just 16 when discussions for the film first began.

I was almost the same age Luanne was at the time, but I was a much younger 16, so I'm glad I had a chance to age before we started shooting," Stewart said.u00a0
