Geimer said she grew uncomfortable when he grabbed her around the waist and started to move her hips around. When she hopped out of the Jacuzzi and retreated to the bathroom, she said, Polanski followed her there and she told him she wanted to go home.
"Yeah, I'll take you home soon," he said, according to her testimony.
"No, I have to go home now," Geimer said she told him.
Geimer testified that Polanski persuaded her to go to the bedroom and lie down. Geimer went, she said, but she sat on the couch in the bedroom. She described Polanski sitting next to her and reaching over to kiss her. Geimer said she told him, "No, keep away" and "Come on, let's go home."
He ignored her, she testified, then "went down and he started performing cuddliness (sic)."
When the district attorney asked Geimer what "cuddliness" meant, she clarified, "he placed his mouth on my vagina."
"I was ready to cry," she said. "I was going, 'No. Come on. Stop it.'"
Instead, a few minutes later, Geimer said, Polanski began having intercourse with her, while asking her if she was on the pill and when her last period was.
She testified that he then asked, "Would you like me to go in through your back?" Then, he started performing anal sex on her.
At one point, Geimer said, there was a knock on the door. The Los Angeles Times reported that the woman was actress Anjelica Huston, Nicholson's girlfriend at the time, but Geimer testified that she did not know who the woman was who was in the house.
According to Geimer, the woman who knocked on the door said, "Roman, are you in there?"
Polanski went to the door and opened it a crack to speak to the woman. Meanwhile, Geimer testified, she put her underwear back on and started toward the door.
When asked why she didn't say anything to the woman, Geimer said, "I was still pretty much afraid of him [Polanski]." She added that he was her only way home.
Geimer testified that Polanski closed the door before she could reach it, took off her panties and began intercourse again. When he finally let up, she said, she went to the bathroom and put on her dress again.
On her way outside to the car to wait for Polanski, she said, she again saw the woman in the house, spoke with her, but didn't tell her what had just happened.
Geimer said she began to cry in the car, and Polanski got in about 10 minutes later and drove her home.
"All hell broke loose" when her mom found out, Geimer told "GMA."
"My sister overheard me telling my then-boyfriend what happened on the phone after I got home. So she went in and told my mom," Geimer said in 2003.
Polanski was arrested the next day. He claimed that the sex was consensual. Geimer said it was not and that she resisted.
Huston later described the teen as "sullen" in a probation report prepared at the time of Polanski's plea deal.
"She appeared to be one of those kind of little chicks between -- could be any age up to 25. She did not look like a 13-year-old scared little thing," Huston said.
Today, Hollywood is still rushing to Polanski's defense. Directors Martin Scorsese, David Lynch and Woody Allen are among dozens in the film industry who have agreed to sign a petition calling for the immediate release of Polanski.
In a British newspaper, film producer Harvey Weinstein, who has already signed the petition, called Polanski's original plea deal a "miscarriage of justice."
