Kalyn Thompson, 25, an English teacher at an Oklahoma high school, is charged with second degree rape following an alleged relationship with a student.
She resigned from her position at Kellyville High School in April.
Investigators say that Thompson had worked at the school for less than a year when she began texting with a 17-year-old male student in December.
The text messages soon took on a sexual nature, administrators told police, and the relationship allegedly began to escalate into full blown sexual activity.
In a police interview, the victim, who is a junior, told investigators that he had sex with Thompson twice ... once at a local lake and once at a Tulsa motel.
"It will follow her for the rest of her career," Creek County Detective Chrissie Underwood said. "She probably will not have a career in teaching after this."
Although the age of consent in Oklahoma is 16, Underwood said that as a teacher, Thompson is an authority figure and therefore guilty of a crime.
"It's sad because they're vulnerable to it, and obviously he's getting good grades from it," she said, revealing the other component to the shocking story.
According to police, the victim was "flunking English last semester" but now that his liaison began, "currently has a 98 percent grade point average."
Maybe he's graded on a curve ... or how he handles hers.
High school staff found out about the relationship after two other students saw Thompson in the victim's truck away from school, took photos, and reported it.
Thompson is currently free on bail awaiting trial.
