The boy has been trying to escape from his class and has been isolated by the school teacher. She returns to the class to find him trying to escape out the window. She grabs him, pulls down his trousers and underpants, over the lap and spanks his bare bottom. While she is doing it, he urinates on her.

The boy should clean a big wine barrel. This cleaning work is traditionally a nude job. So he strips and enters the barrel.
