TISHOMINGO, Okla. – Court documents detail sexually suggestive text messages police say were exchanged between a Johnston County teacher and a 14-year-old boy.

State agents arrested 48-year-old Shelley Jo Duncan on Friday, accusing her of having inappropriate contact with a minor.

The Oklahoma State Bureau of Investigation apprehended her in the parking lot of the alternative education building.

According to an affidavit obtained by NewsChannel 4, Duncan and the boy told each other “I love you” and called each other “boo.”

“U have no idea what u mean to me,” Duncan wrote the boy, according to the affidavit. “I’m here for the rest of ur life…I can’t imagine my life [without] u in it.”

Other messages detail the pair’s plans for future sexual encounters, including Duncan allegedly texting the boy she would give him “oral sex with a cough drop in her mouth.”

According to court documents, Duncan allegedly told the boy: “I’m glad you love your mom so much. One of the many reasons I love you.”

When the boy replied his mom was “[his] world,” investigators say Duncan responded: “Probably the hottest thing u’ve ever said. Nothing hotter than a man that takes care of his mom.”

Ultimately, it was the boy’s mom who told police of the suspected inappropriate relationship, which according to the court documents, moved beyond words.

The pair also went to a movie with Duncan’s daughter. The boy told police he and Duncan touched each other during the movie and kissed each other when the daughter fell asleep on the drive home.

A week later, the boy told investigators, Duncan picked him up and took him to her place of employment. There, according to documents, the boy “put his hands down Duncan’s pants, and brushed, ‘that area down there.'”

According to court documents, the boy told police Duncan was concerned about the consequences of her alleged actions.

“She knew it was wrong, and that she could go to prison,” the boy said, adding that she didn’t want her mugshot on the news, according to the affidavit. “She told him not to tell anyone because it could ruin a lot of stuff, such as: her relationship with him, her relationship with her kids and her job.”

Dr. David Croninger is a licensed therapist, who works with people battling sex addiction. He said he can’t diagnose Duncan without meeting her, but says her behavior could be a sign of addiction.

“Much of the addiction cycle is about compulsive thinking,” he said. A person compulsively thinks about sexually acting out because that’s what helped them feel good. Eventually they’re going to do it and they’re going to do it over and over again until they get caught.”

The boy’s account that Duncan knew it was wrong is consistent with the things Croninger sees from all kinds of addicts.

“Persons, whether they know right from wrong, when they have an addiction, they have to,” he said. You have to act out. There’s a craving set up. There’s a sense of needing to do it that’s beyond a person’s control.”

Cell phones and social media have made things more difficult because they make things more accessible, Croninger said, which he feels has certainly contributed to what he calls an “exponential rise” in sexual addiction, from which it can take at least two years to recover.
