A class of students got a sex education lesson they didn't bargain for when their teacher accidentally showed them home made porn of her and her fiance.
The US teacher at Little Rock, Arkansas, admits making the sex tape and says it somehow got mixed up in her lesson plans.
Nicolar Tolerson, whose son saw the video, is none too happy with the incident.
"(My son) says she was performing sex acts," Tolerson told KARK-TV. "My heart goes out to not only my son, but other kids in the classroom."
The teacher called parents later in that day to apologise and the school is investigating, according to Fox16.
