Bill Cosby admitted to plying teens with booze and drugs before having sex with them, and to having girls regularly dispatched to him by a modeling agency, newly unearthed court papers show.

The comic said that at one point in his career, the agency would provide “five or six” young women each week, according to depositions he gave in 2005 and 2006 for a lawsuit.

Among other revelations made by Cosby under questioning by lawyers for Andrea Constand, who claims he sexually assaulted her in 2004, was the description of a 1976 encounter with a 19-year-old model named Therese Picking.

He said he gave Quaaludes to Picking, now called Therese Serignese.

“She became, in those days, what was called high,” Cosby said.

Constand’s lawyer asked whether Serignese gave consent for sex.

“I don’t know. How many years are we talking about? 197[6]?” he said. “I meet Ms. Picking in Las Vegas. She meets me backstage. I give her Quaaludes. We then have sex.”

Cosby said he paid off Serignese through his reps at William Morris to keep her quiet.

He admitted he needed to prevent at least one person from finding out.

“Mrs. Cosby,” he said.

The admissions in the 2005 and 2006 depositions were revealed one day before Cosby, 78, is scheduled to be in court for a preliminary hearing in a sexual-assault case involving the claims made by Constand, now 43.

In the deposition, Cosby admitted giving pills to Constand, then an employee at his alma mater, Temple University in Philadelphia.

“I don’t hear her say anything . . . And so I continue and I go into the area that is somewhere between permission and rejection,” he said.

Cosby also recalled getting numerous models sent to him each week by an agency he didn’t name. He did not say when the encounters took place or identify any of the women.

He did, however, describe a woman, either 18 or 19, who came to his home in 2000 to talk about her acting career. He said he pulled out a bottle of lotion.

“On a later occasion, you had her masturbate you with lotion, did that ever happen?” Constrand’s lawyer asked.

“Yes,” he said.

“[She] used the lotion to rub your penis and make you ejaculate?” Cosby was asked.

“Bingo,” he replied.

In another case, involving a 19-year-old in New York, Cosby admitted giving her booze and massaging her back. He insisted they stopped short of sex.

The Pennsylvania Supreme Court on Monday denied Cosby’s request to delay the pretrial hearing.
