Watch at: 서울의 한 남녀공학 고교 교사, 복도에서 ‘자위 행위’
This is a contracted korean teacher in Seoul. Got upset with two boys for listening to headphones while studying. Punches them both in the face. Brings them down to the teachers office and punches them again. Male teachers try to help and receive similar blows. The guy then heads to the girls classroom hallway and exposes himself and starts wanking. Highschool insanity ensues.
