The man, who the Fuldaer Zeitung said had been teaching at the Richard-Müller school in Fulda, Hesse, only admitted his involvement after the school director told him he could be clearly identified in the films, one of which was called “Luscious Lad” after the teacher's character.
Although the teacher had not broken any laws, as a public servant, he has a duty to behave in an upstanding fashion in his free time as well as while at work.
A disciplinary investigation will be held into his activities, which is likely to result in a fine and an official note of disapproval.
He will be transferred to a different school in another town, the paper said, and will start working there from Monday.
“This is an unpleasant situation not only for the other teachers, students and parents, but also for him,” said Michael von Rüden, head of the local education authority.
