An Alabama math teacher at a private Christian school is accused of having sex with two teenage boys who had both been her students, according to an arrest warrant obtained by Fox News Digital.

Chrystal Frost, 35, a married mother of three, resigned last month from Crenshaw Christian Academy, known as Home of the Cougars for its football team, after she was allegedly caught exchanging explicit photos with a student on Snapchat.

"Frost sent an obscene photo and asked that the student send a photo from the abs down," according to a police report. 

The school received an anonymous tip that a 15-year-old student, identified as GT, had a "nude breast photo of the math teacher on his phone," which he had shared with some classmates.

An administrator confronted Frost, who allegedly "admitted to a different photo she sent to the cheerleaders where she pulled her Nike shorts up high allowing her butt cheeks to show, took the picture and sent it as a joke."  

Frost resigned Aug. 24, and the next day, the school reported the incident to the Luverne Police Department, which launched an investigation.

A student told police that GT had shown him the breast photo and then dropped a bombshell. He said GT and the teacher had been intimate.

In an Aug. 29 interview, GT admitted that his teacher sent him the lewd photo and then offered him sex. They met on a piece of land owned by his family in Pike County at least four times for the sick trysts.

On another occasion, when he went to feed the dogs as part of his chores, she met him and "performed oral sex on him" in a car. The student said he put an end to the disturbing relationship in early summer.

Police tracked down a second teenager, a 16-year-old student identified as AP, who was Frost's student the prior school year. Frost allegedly used the same tactics to prey on him.

The two met on a farm only once, where they allegedly had oral sex and intercourse. "The teacher made no conversations with him from arrival to ending of the sexual contact," the report said. After the encounter, Frost allegedly sent two more lascivious photos and then blocked him from Snapchat.
