How Much Pain for Confession?

Our sexy Principal has so much on her plate nowadays, she really has no time to discipline her students. But when she is notified a student was caught in the shower fooling around with another, she makes time for a punishment. She calls the student into her office, but she isn't confessing. The Principal figures she needs to make her blurt it out. What works better than some pain? She pulls her naughty student over her knee and spanks her with a bare hand over her white panties. But, the student isn't saying a word. Maybe the back of a wooden brush against her thighs can get the truth out. This is one tough student. But our dominating Principal loves a challenge. She bends the girl over and uses her new leather slapper against already red skin. Still not a word. Let's see if this student can withstand a violent caning.
