A 42-year-old suburban mother of three is accused of having sex with a 17-year-old soccer player.

The inappropriate relationship was uncovered when an Upper Pottsgrove Police officer allegedly found Iris Gibney and the teen naked, having sex inside a parked car. The car was illegally parked in Hollenbach Park in Pottstown, Pennsylvania, after closing around 10:30 p.m. Nov. 15.

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 17-year-old Pottsgrove High School student said he met Gibney at a high school football game earlier this year, police said. She had been volunteering as a "cheer mom" for the cheerleading team that her daughter is a part of.

Confronted about the alleged affair, the teen told the officer he couldn't lie and admitted he was having sex with Gibney, according to police records.

Gibney, who works as an associate at Victoria's Secret in King of Prussia, told the officer, "I’ve never been in trouble before. I can't believe I did this. I have three children of my own — I am so, so sorry," according to the arrest report.

UPDATE: Gibney's attorney said this whole incident left her "heartbroken" as she tried to put her life back together.

Further investigation revealed Gibney and the teen communicated through Twitter and a public chat room. Gibney then sent the boy several partially nude photos from her cellphone to his, police said.

As part of their investigation, police confiscated the boy's phone and found the sexts from the Pottstown woman, investigators said.

Gibney turned herself in Tuesday to be arraigned on charges including corruption of a minor, dissemination of explicit materials to a minor and trespass by auto.

She posted $50,000 unsecured bail and left custody Tuesday afternoon, said the Montgomery County District Attorney. She made no comment as she walked to her car.

She was back at work Tuesday night and declined to comment when contacted at the retail store.

Speaking briefly to NBC10, Gibney's husband said he's upset, hurt and just trying to keep his family together.

She faces a preliminary hearing later this month, according to court records.
