Over dinner, she says, Cosby started passing out pills. "So then he reached over, because I was not being bubbly, and he put a pill down next to my glass and said, 'Here, take this. You'll feel better.'"
"Did it make you feel better?"
"No. I started feeling like I was going to drop my face in the plate."
Valentino says Cosby drove them to a Hollywood apartment where her friend passed out cold. It was then, she says, that Cosby forced himself on her.
Smith asked, "Did you think about going to the police?"
"It was the '60s, and in those days, rape victims were re-victimized," Valentino replied. "It wasn't compassion and protection of the victim. Oh, no, it was, 'Well, what were you wearing?'"
So Valentino kept her mouth shut. And for decades, despite rumors of indiscretions, Cosby's secret was pretty much safe.
But Cosby became a sort of moral crusader in recent years, scolding young African-Americans ("Please, stop it. Stop your cursing"). Some saw his preaching as the height of hypocrisy, and late last year, standup comedian Hannibal Burress openly called Cosby out as a rapist:
"'I was on TV in the '80s, I can talk down to you, because I had a successful sitcom!' Yeah, but you rape women, Bill Cosby!"
The video went viral, and inspired a wave of Bill Cosby accusers.
When asked why she came forward, Valentino replied, "Hannibal Buress. We didn't all conspire - 'Hey, let's meet in 2014 and all get together and nail this guy, you know, and, oh, yeah, we'll have the big reunion,' you know? I mean, who would have thought? It was like one more woman coming out and you're going, 'Oh, my God. Oh, my God.'"
We reached out to Bill Cosby; his representative told us that there would be no statement or comment for this story.
"I think heroes so die hard in the black community, for pretty clear reasons -- we haven't had a lot of heroes for a real long time," said Columbia University visiting scholar Obrey Hendricks, who says that revulsion over the Cosby allegations is pretty universal.
"There are many who just don't want to believe it, they can't believe it, they don't want to see that their hero does something like this. But 50 women have accused him of rape, and that's sort of hard to get over and to overlook," said Hendricks. "And if only one of them is telling the truth, then that means that he's a rapist."
Some of those women are working together now to change statute of limitations laws, if not for them, then for future victims of assault.
And that could be Bill Cosby's real legacy.
Smith asked, "Could it be that Bill Cosby goes to his grave with all of this still going on?"
Professor Levenson replied, "I think one of the strategies here is to say to Bill Cosby, 'You will never have peace. For the rest of your life we will be pursuing you. We may not win at every turn, but we will be there.'"
