Andrea Constand's mom — Gianna Constand — gave a testimony Wednesday about a previous confrontation she had with embattled comedian Bill Cosby over the phone. He allegedly drugged and sexually assaulted her daughter in 2004.

"He admitted he was a sick man," Gianna revealed during day three of the trial, according to NBC.

While not to Cosby's knowledge, Gianna's "motherly instincts" came into play. Therefore, the victim's mother wisely recorded her conversation with Cosby on her cell phone in 2005. According to USA Today, this recording occurred a year after the 2004 incident with Cosby and her daughter.

As the audio recording continued to play itself out, the Pennsylvania courtroom that the trial occurred in was quickly immersed with the sound of the comedian's distinctive voice. It was impossible to deny that it was his voice on the mother's recording.

"I would be willing to...meet with you guys," Cosby said in the recording. "Lay out what I think is best. Pay for the schooling.

In addition to offering to cover Constand's schooling during the phone call, USA Today also claimed that Cosby revealed details of the sexual encounter with the victim's mother.

"He said, 'Don't worry, mom, there was no penetration, just digital penetration,'" Gianna said. "He said to me, 'And, mom, she even had an orgasm.'"

According to NBC, "Cosby sat stone-faced as he listened." The comedian most likely had not anticipated that his private revelation to Gianna was recorded. Nonetheless, his attorney's attempted to dismiss her credibility, according to Vanity Fair.

Cosby has denied assaulting Constand because he had seen the incident with her as an ordinary encounter of consensual sex.

"I walk her out," Cosby said, according to another Vanity Fair article. "She does not look angry. She does not say to me, don’t ever do that again. She doesn’t walk out with an attitude of a huff, because I think that I’m a pretty decent reader of people and their emotions in these romantic sexual things, whatever you want to call them."

Likewise, Vanity Fair also noted Constand's lawyer responded with "he did not realize plaintiff was gay until the police told him."

Cosby had apparently called Gianna again the next day. The second phone call follows the previous session she nabbed a recording of him, according to NBC.

"He is telling me everything he physically did to her," Gianna said in court. "He said he was touching her breasts and he said to me, 'But don’t worry, mom, there was no penile penetration, just digital penetration.'"

Leading up to the trial, over 50 women have accused Cosby of either drugging and/or sexually assaulting them, according to ET Online. Additionally, ET Online also noted that "the alleged incidents date as far back as 1969." However, the comedian has publicly denied all accusations. He cannot be charged with these alleged crimes in court because they exceed the statue of limitations.

Despite this, thanks to Gianna's recording of Cosby, this could be the one thing that drives the Pennsylvania court system to send him to prison.

Cosby pleaded not guilty to all the charges against him.
