鞭打在她光秃的屁股上

Aileen, D grades again. D grades. What did I tell you two weeks ago? I don't want to

see D grades anymore. I know sir. You see this? Yes sir. This is my answer for D grades.

Yes I know that sir. I want to see A grades and B grades. Yes I know sir. Certainly no

D grades. No sir. I'm sorry sir.

Get up, trousers down, I want to see your bottom.
