Former models Linda Brown and Lisa-Lotte Lublin were joined by attorney Gloria Allred, who represents many of the other accusers, for a press conference on Thursday.
Brown says she met Cosby in 1969 when she was 21. He invited her back to his hotel room to give her a gift. Upon arrival, Cosby gave her a soft drink and Brown blacked out. When she woke up, she was naked in bed with him and says she had been raped.
"I felt like a rag doll and like a real-life blow-up doll for him" Brown said. "I felt dirty, ashamed and embarrassed," and fooled into thinking Cosby "nice, trustworthy and honorable."
"I want people to know who Mr. Cosby really is: He has a Dr. Jekyll-and-Mr. Hyde personality and if you trust him, then he has fooled you as well," Brown continued.
Lubin says she met Cosby two decades later in a Las Vegas hotel in 1989. She says she was 23 when Cosby offered to evaluate her acting skills and insisted she have a drink to relax.
"I trusted him because of who he was, and how well he was respected around the world," Lubin said. "The taste was horrible and unfamiliar to me because I was not a drinker."
After the drink, Lubin became disoriented, but says she remembers Cosby wrapping himself around her and stroking her hair until she passed out. She woke up at home with no memory of what had transpired.
"Bill Cosby appears to think that rape is a joke," Lubin said. "Let me tell you something, Bill, I'm not laughing."
Lubin said she planned on leading a campaign to make Nevada legislators throw out the statute of limitations for sexual assault. "I will do everything in my power to change the law that protects criminals and re-victimizes the innocent," she said.
Since November, nearly three dozen women have come forward accusing Cosby of drugging and raping them over the past five decades. And according to Allred, there are more victims who haven't yet spoken out.
"Mr. Cosby thinks that this will soon be over and that no more women will come forward," Allred said. "He is very wrong. I still have many women who have not yet come forward, but who are willing to do so in the future."
