鞭打屁股的莉娅-帕克、麦德琳-马洛女主人

That's an appropriate punishment for a schoolgirl for not doing her homework: Stripped naked in the classroom while tied up and exposed in front of all her classmates. And only because of this humiliation she'll now do her homework. And to remember that, the teacher recorded everything on her smartphone. So for the next time, she'll just upload her exposing punishment on Facebook or/and the school website! → Best teaching ever!
