A 32-year-old English teacher admitted in court Thursday that she had sex with a 16-year-old student, in a forgiving plea deal that gets her out of serving any prison time or having to register as a sex offender. Former Destrehan High School teacher Shelley Dufresne was arrested in September after the teen in question started bragging to friends at the St Charles Parish, Louisiana school that he had slept with two teachers. An investigation later revealed that the unidentified teen had sex with both his current English teacher at the time, Dufresne, and his English teacher from the prior year, 24-year-old Rachel Respess - including an alleged a threesome with both at Respess's house.

Double the trouble: Dufresne (right) and fellow teacher Rachel Respess, 24 (left), were arrested in September when a student at Destrehan High School started bragging that he was sleeping with both of them . How they met: The unidentified 16-year-old victim was a student in Dufresne's English class last year. Respess taught the same student English the year prior . Though she originally pleaded not guilty in November, married mother-of-three Dufresne changed course and confessed to the sordid act at a status conference in court on Thursday. In exchange for pleading guilty to a count of obscenity, the original charge of carnal knowledge of a juvenile will be held for the three years Dufresne is under probation for obscenity. Comfortable: As part of her plea deal, Dufresne will not have to serve any jail time. Instead she will undergo a 90-day inpatient mental health treatment program, surrender her teacher's license and stay away from the victim and his family . Dufresne must also undergo a 90-day inpatient mental health treatment, surrender her teacher's license, and stay away from the now 17-year-old victim and his family. If she complies with all of those terms, the carnal knowledge charge will be dropped after three years and she will not have to register as a sex offender. The carnal knowledge charge carries a maximum of ten years in prison and a fine for $5,000. Judge Anne Simon signed off on the plea deal, after three other judges - including Dufresne's father Judge Emile St Pierre - removed themselves from the case. District Attorney Joel Chaisson II heralded the deal as a success. 'I want to thank my special prosecutor, Julie Cullen, for her efforts to reach a fair resolution of the case and to secure a felony guilty plea, thereby sparing the juvenile victim in this matter from having to testify at a public trial,' the DA said in a statement. The parents of the victim were in court on Thursday, and according to media who attended the meeting, they were not happy with the settlement. However, Dufresne's legal battle is likely not over yet. When her relationship with the teen was exposed last fall, it was revealed that she had sex with the teen at a residence in Montz (Dufresne and her family live in Montz) and one in Kenner between August 22 and September 27. Dufresne still faces the possibility of jail time for allegedly having a threesome with the same student and Respess at Respess' residence in another Louisiana parish (pictured above). Neither woman has been formally arraigned on those charges yet . Above, Dufresne's home in Montz, Louisiana. The charges she settled Thursday had to do with sex acts she and the 16-year-old committed at a residence in that town . Both towns fall under different parishes, and Jefferson Parish has yet to formally arraign Dufresne on charges of carnal knowledge with a juvenile, indecent behavior with a juvenile and contributing to the delinquency of a child. It was at Respess' home in Kenner that the teachers allegedly had a three-way with the student after a high school football game in September, and that is the incident they await arraignment on. Since her arrest on September 30, Dufresne has remained free on bond. While she has been under house arrest during this time, the rules of the sequester have been loosened so that she can attend therapy sessions, Jazzercize classes and help drive her 3, 5, and 7-year-old children to school and extracurricular activities. However, she had to spend 8pm to 7am inside her home during the weekdays. Both Dufresne and Respess were suspended from their jobs without pay following their arrests last fall.
