A married headmaster was caught in the act by students giving oral sex to a female maths teacher during school in Slovenia.
Students said they found 41-year-old father of two Drago Kamenik between the legs of Manja Mertelj (45) when they walked into a classroom they believed to be empty after they heard moans of pleasure.
The embarrassed head-teacher first threatened to sue students who uploaded a clip of the pair onto social media and then denied it was real after the clip went viral.
