A Good Old Fashioned Spanking

Charli has been a misbehaving student and principal Kross has had enough. He plans to send a strongly worded note to her parents. Charli begs him not to, graduation is not far away and she wants to go to an out of state college, which her parents wont allow if they know shes been bad. Mr. Kross proposes she take her punishment the old school way, and demands she bend over his desk. Reluctantly, she agrees. Mr. Kross lifts her skirt up and starts by spanking her over her white old style panties. Shocked, Charli promises to stop being a brat and act like a big girl from now on. Mr. Kross announces that, since she is a big girl, she can take her punishment as one, and pulls down her panties. Charli is humiliated and shocked but has no choice but to take her punishment. Once her ass has gotten nice and pink from spanking, Mr. Kross pulls out a crop and then a cane, working her naked ass and thighs till both are red and marked, and Charli is moaning in pain. How much will it take till shes finally, really learned her lesson?
