A new audio has resurfaced that revealed actor and comedian Bill Cosby joked about "drugging" women with Spanish Fly.

In the audio from Cosby's stand-up act, he is heard saying: "Go to a party, see five girls standing alone. Boy, if I had a whole jug of Spanish fly I'd light that corner up over there. Haaa ha ha."

Meanwhile, a second victim has come forward claiming Cosby had drugged and raped her on two occasions in 1969 when she was 19, reported CBS News.

According to Joan Tarshis, Cosby had invited her to consult on material for his comedy act and gave her a cocktail on The Bill Cosby Show.

"I was sitting up writing one second and the next second I was lying down on the couch having my underwear taken off. He gets you into a position where you think you're going to work with him, and then he drugs you and rapes you," Tarshis told "CBS This Morning".

Tarshis accused Cosby of being a "serial rapist" and says she did not report the 1969 rape incident as she felt no one would believe her.

"Nobody else had come out. I didn't know his history. I assumed I was not the only girl he was doing this with, but who's going to believe me? They would probably think I was out to get something," said Tarshis.

Tarshis is the fifth woman to come forward accusing Cosby of rape.

On Sunday, Cosby's lawyer John P. Schmitt said his client will not dignify "decade-old, discredited" sexual assault claims.

"He would like to thank all his fans for the outpouring of support and assure them that, at age 77, he is doing his best work," Schmitt said in a statement released to The Associated Press.

The ring of accusations directed at Cosby started from a stand-up performance in Philadelphia, Cosby's hometown, when comedian, Hannibal Buress, called him a "rapist".

One of Cosby's victims, Barbara Bowman, accused the entertainer in an online column for the Washington Post, where she said that in 1985 when she was only 17 and aspiring to be an actress, Cosby, "brainwashed me into viewing him as a father figure, and then assaulted me multiple times."

Cosby has never been criminally charged for rape, however, he settled a civil suit against him in 2006 when a woman accused him of a similar assault.
