The schoolboy told police tutor Shelley Duncan, 48, once said she would give him oral sex with a cough drop in her mouth.

A teacher married to her school’s boss has been accused of having sex with a 14-year-old pupil.

Former probation officer Shelley Duncan, 48, called the boy “boo” and “love” in texts found on his phone, police said.

The teenage schoolboy claimed Duncan once told him she would give him oral sex with a cough drop in her mouth, it is alleged.

He and the blonde mum discussed where they had sex on the Snapchat app so the messages would be erased, he reportedly told investigators.

He also told law enforcement that Duncan took him back to where she worked where they undressed before touching each other inappropriately.

Duncan was arrested in the car park of Tishomingo High School, Oklahoma, on Friday after the lad’s mother told police her son was having an affair with the English tutor.

The state’s Bureau of Investigation spokeswoman Jessica Brown said: "We believe there was an inappropriate sexual relationship between this women and a young male student.

"We were searching for her found her at the school."

Duncan, a certified child counsellor, has been charged with lewd or indecent proposals or acts with a child under 16.

She could be jailed for up to 20 years if convicted.

Her husband Kevin is Tishomingo Public Schools Superintendent.

He says in a message on her school’s website: “Our children are our most precious resource and our goal as educators is to teach the value of an education as well as provide a foundation of learning that will prepare them become successful members of our community.

“We invite you to participate in your child’s educational journey as they strive to attain their goals.

“We look forward to a bright and successful school year.”

Duncan, who is also a cheerleader coach at the alternative education school, is on reserve with the Murray State College Police Department, said KXII-TV.

She worked at the Office of Juvenile Affairs as a Juvenile Justice Specialist from 1998-2006, NewsChannel 4 reported.

Then she moved on to the Department of Corrections, where she worked as a probation and parole officer. She resigned in 2012.

Duncan was released on bail.

Her husband has so far declined to comment.
