"I made a horrible decision and have been in therapy since it happened," a 42-year-old Montgomery County mother accused of having sex with a 17-year-old boy told a judge Tuesday.

And with that, Iris Gibney, a mother of three, plead guilty to less serious charges, agreeing to serve five years' probation, attend counseling and serve 100 hours community service, according to NBC-10 in Philly. She must also pay a fine.

Iris Gibney, 42, and a mother of three, pleaded guilty to less serious charges after being accused of having sex with a 17-year-old boy in a car. The Montgomery County 'cheer mom' met the teen at a high school football game, where she had been volunteering as for her daughter's cheerleading team.

It could have been far worse, as the suburban mom faced charges of corruption of a minor, dissemination of explicit materials to a minor and trespass by auto.

Ultimately, Gibney admitted only to corruption of a minor and sending the photos.

Last November, an Upper Pottsgrove Police officer allegedly found Gibney and a 17-year-old boy naked, having sex inside a car illegally parked in a Pottstown, Pa., park.

As the officer approached the car, he saw Gibney performing a sex act on the teen, according to an affidavit of probable cause obtained from police.

The Pottsgrove High School student told police that he met Gibney at a high school football game, where she had been volunteering as a "cheer mom" for her daughter's cheerleading team.

Gibney works as an associate at Victoria's Secret in King of Prussia. She can no longer have any contact with the boy.
