Bill Cosby's chief accuser took the stand at his sexual assault trial to tell her story publicly for the first time, saying the comedian gave her pills that left her paralysed and helpless, before groping her.
"In my head, I was trying to get my hands to move or my legs to move, but I was frozen," Andrea Constand, a former basketball manager at Temple University, Cosby's alma mater, said in their long-awaited courtroom confrontation.
She added: "I wasn't able to fight in any way. I wanted it to stop."
Cosby, 79, is charged with drugging and violating Ms Constand at his suburban Philadelphia home in 2004. The TV star once dubbed America's Dad could get 10 years in prison if convicted.
Ms Constand, 44, said Cosby assaulted her after giving her three blue pills he claimed were a natural remedy to ease her stress about a looming career change. She said she started feeling woozy after about 20 minutes, with blurred vision and slurred words, before he abused her.
Afterwards, she said, "I felt really humiliated and I felt really confused".
Cosby stared down at the defence table, resting a hand across his forehead, as Ms Constand testified.
Before Tuesday, Ms Constand had never spoken about Cosby in public, barred from doing so under the terms of a confidential settlement they reached in 2006. Her deposition from that lawsuit remains sealed.
Some 60 women have come forward to say Cosby sexually violated them, all but destroying his nice-guy image on screen and off, but the statute of limitations for prosecution had run out in nearly every case. Ms Constand's case is the only one in which Cosby has been charged.
The stage was set for Tuesday's confrontation after prosecutors used the first day and a half of the trial to argue that Cosby made a habit of knocking women out with pills and then molesting them.
Kelly Johnson testified on Monday that Cosby drugged and molested her at a Los Angeles hotel bungalow in 1996.
She said she lost consciousness soon after Cosby pressured her to take a large white pill. She said that when she awoke, Cosby was naked and abused her.
On Tuesday, Ms Johnson's mother, Pattrice Sewell, bolstered her daughter's story, telling jurors that Ms Johnson was distraught during a telephone call in 1996, fearing Cosby was trying to get her sacked from her job working for the comedian's agent.
A few weeks later, Ms Sewell said, Ms Johnson disclosed that she had woken up next to Cosby in bed with her clothes askew.
The defence has attacked Ms Johnson's credibility over discrepancies in her accounts, including the year it occurred. Cosby grinned at the defence table as she struggled to explain them.
Ms Sewell said they did not go to police at the time because her husband, a Los Angeles detective, feared the ordeal that would ensue.
"Her father didn't want her to be humiliated and feel shame and embarrassment as he had seen other women go through when they went to the police at that time. He didn't want that," Ms Sewell said.
Ms Johnson told a similar story in 1996, when she gave sworn testimony in a deposition attached to a worker's compensation claim.
Joseph Miller, a workers' compensation lawyer, testified on Tuesday that he was taken aback when Ms Johnson said she had been drugged and violated by Cosby. He said Ms Johnson made the disclosure while pursuing a claim that she had developed debilitating stress from her secretarial job at the William Morris Agency.
Mr Miller, who represented William Morris in the case, said Ms Johnson was tearful as she described waking up on a bed with her dress pulled down - details that matched the story Ms Johnson told on the stand.
But Mr Miller's timeline differed from Ms Johnson's.
Under questioning from Cosby's lawyers, Mr Miller revealed that his notes from her 1996 deposition show Ms Johnson told him the encounter happened in 1990.
Mr Miller testified that no transcript was made of the deposition itself, an agreement he struck with Ms Johnson's lawyer because of the sensitivity of her claims. He said her testimony hastened a settlement of the workers' compensation claim for around $10,000.
