Former Kennedale High School teacher Brittni Colleps insists she's not a sexual predator but says she feels like a victim after students she engaged in group sex with took a sex video without her consent.Colleps speaks out for the first time since being sentenced to five years in prison last month in an interview with "20/20" that airs tonight at 9 CDT on WFAA/Channel 8.Colleps, who turned 29 on Thursday, was convicted of 16 felony counts of improper relationship between an educator and student. She remains in the Tarrant County Jail awaiting transfer to prison.Prosecutors say Colleps had sexual relations with five of her students, including a group sexual encounter with four which was videotaped on one of the teen's phones. The video was shown to jurors during the trial."I felt like I was victimized in that video, because I did not, I never gave my consent for it," Colleps told "20/20."In the interview, Colleps also said while teachers having sex with students may be wrong and immoral, she does not believe having sex with consenting adults should be illegal. All of the students were 18 or older.Colleps has appealed her convictions. Her appellate attorney has also filed a motion for a new trial, court records show.
