She said she became woozy and Cosby helped her to a bed, where he lay next to her, grabbed her breasts, humped her and grunted.
She rejected a defense lawyer's insinuation that she would do anything to help the comedian's chief accuser, Andrea Constand.
Constand testified that she and Cosby had been discussing her aversion to traditional medicine for 18 months and that he must have known that she doesn't "even like to take Advil".
"I talk about trust that was built over time, that was built by the defendant", said Steele, as quotes from a 2005 deposition Cosby gave flashed on a large screen in front of the jury, writes Laura Benshoff of member station WHYY.
The police report filed by Chelan Lasha (shuh-LAWN' LASH'-uh) lacked numerous details she testified about Wednesday at Cosby's sexual assault retrial.
Cosby's legal team at his first trial wasn't almost as aggressive in attacking Constand, focusing instead on inconsistencies in her statements to police and arguing the pair had a romantic relationship.
Could we see a guilty verdict in the Bill Cosby trial this time?
The closest she got to speaking with him directly, she testified, was posing for a quick photo with Cosby after eating dinner with him and a group of his friends after a show.
In his opening statements, defense attorney Tom Mesereau said Cosby confided in Constand that he never got over the death of his son, Ennis, and that he was lonely.
The defense calls Constand a "con artist" who made up her allegation in order to file a civil suit against Cosby.
The case has trashed the legacy of the actor once adored by millions as "America's Dad" for his role as lovable father and obstetrician Cliff Huxtable on the hit 1984-92 television series "The Cosby Show".
First trial: "He opened his hand and he had three blue pills in his hand". She said Cosby stopped her as she went to leave: "All he said was there's a muffin and tea on the table and then, "All right" and then I left". In a prelude to that culture shift, some 50 women accused Cosby of molestation going back decades. "He's not on trial for any of this", O'Neill instructed the jury of seven men and five women.
Bill Cosby's main accuser will testify during his sexual assault retrial Friday after several other women told jurors this week they believe he drugged and molested them. Unprompted, Lasha looked at Cosby and addressed him from the stand.
Janice Baker-Kinney testified that in 1982 she went to the house Cosby stayed in near Reno, Nevada, when she was told he was having a pizza party.
"Since this American citizen didn't adhere to Ms. Allred's ransom notice, she paraded in a stable of women to destroy his legacy, his career and reputation", Wyatt said.
Under questioning by prosecutors Wednesday, Baker-Kinney said she has long blamed herself for taking the pills that Cosby gave her.
She says she was still incapacitated and "was not able to do anything" about the assault.
Bill Cosby's lawyers are arguing in court at his sexual assault retrial that jurors should hear about an accuser's criminal past so they can fully assess her credibility.
Intention in a case like this can come up in cross-examinations, but Cosby could simply continue to insist that he sought not to sedate Constand but to simply give her something that would soothe her. Defense attorneys claim that Constand not just determined travel rooming arrangements for the basketball team's away games, but shared a room with Jackson at least six times.
Constand offered brief details of seven social encounters she had with Cosby before the alleged assault, including one in which she said he put his hand on her thigh and another when she said he tried to "unbutton my button on my trousers".
"I couldn't fight him off", testified Andrea Constand, then operations manager for the women's basketball team at Temple University and now a massage therapist living in Canada. Only one of the more than 60 women who have accused him was permitted to testify at the first trial, which ended with a hung jury.
The Associated Press doesn't typically identify people who say they're victims of sexual assault unless they grant permission, which Constand has done.
