A female teacher has been accused of engaging in oral sex and intercourse with a 14-year-old male student - allegedly inside the school.

Jessica Langford, 32, has pleaded not guilty to three counts of sexual battery and three counts of unlawful sexual conduct with a minor at the Ohio middle school, according to court records viewed by the Dayton Daily News, reports the Bulletin.

Langford made her pleas on November 21, but additional information about her case recently came to light in response to a defence request for more specific accusations.

The maths teacher, who had worked at Miamisburg Middle School in US for nine years, allegedly performed oral sex on, received oral sex from and engaged in intercourse with the teen student twice. The sex acts reportedly occurred May 23 at the school.

The student allegedly told another teacher about the sexual encounters with Langford, and that teacher then told administrators.

‘We did our own little, quick investigation at that point,’ said Miamisburg Superintendent Dr David Vail, adding that, after Langford was placed on administrative leave, she chose to resign. ‘Because of that fact, we were mandated to report it to the Ohio Department of Education.’

Langford was the second teacher to be busted for alleged sex with a student in the Miami Valley area during a two-week span in November.

Madeline Marx, a 23-year-old substitute teacher who worked at another school, was accused of trysts with two students and arrested earlier in November.

Meanwhile, a high school teacher in Oklahoma was fired Thursday after she and her 16-year-old student allegedly applied for a marriage license, the New York Post reported.

‘You’d certainly think … someone would say ‘I shouldn’t do that,’ but it doesn’t occur to them,’ said Spt Vail.
