Trigger Warnings: foalcon, blackmail, spanking, degradation, humiliation, domination/submission, Diamond Tiara being evil.

Everypony likes Miss Cheerilee. Her students love her, their parents trust her, she is valuable, much loved member of the community. Nopony has anything against her.

Except Diamond Tiara. She is fed up with the blatant lack of respect from the teacher. Who does she think she is? Protecting those stupid blank flanks, telling Diamond Tiara off when she catches her amusing herself. So what if she''s hurting the feelings of the other foals? It's not like they're important.

This detention is the final straw. Diamond Tiara is going to make things right. She is going to teach her 'teacher' respect.
