The woman whose lawsuit led a federal judge Monday to unseal a 2005 deposition in which Bill Cosby testified that he gave a woman drugs before sex may ask the judge to unseal all of Cosby's testimony, sources told NBC News on Tuesday.

Dolores Troiani, the attorney for the main plaintiff in the suit — which was dismissed in 2006 — is making contact with 13 other women in the case to make sure they're OK with the request to release the full deposition, the sources said.

Cosby's lawyers had fought to keep the documents secret, saying they would be "terribly embarrassing."

More than a dozen women have accused Cosby since then of having sexually assaulted them. Cosby, 77, who has never been charged with a crime, denies the allegations and is trying to get several court cases thrown out.

But documents unsealed Monday in Pennsylvania showed that Cosby admitted in the 2005 deposition that he obtained prescriptions of the powerful sedative methaqualone, better known by the brand name Quaalude, to give to women he wanted to have sex with.

Cosby recounted one encounter in the 1970s in Las Vegas with a woman whose name was redacted in the document: "She meets me back stage. I give her Quaaludes. We then have sex."

The documents were unsealed after a victorious court fight by The Associated Press. U.S. District Judge Eduardo C. Robreno said Monday he granted the AP's request because of the disconnect between Cosby's upright public persona and the serious allegations against him.
