Reform School - severe thrashing.

When a girl seriously misbehaves, she is punished with a severe thrashing and this is never rushed.
Time is taken to bend her over something solid that will keep her in position throughout the lengthy beating. Her thighs are tapped with the cane so she can feel its thickness and dread the pain to come. And then she is made to straighten her legs and rise on tiptoe to obediently offer herself to be thrashed.
Her fear and anxiety increase as the teacher grabs her bottom and makes it clear that it is his for however long the punishment takes. Then he pulls her skirt right up, leaving her exposed in her knickers long enough for her to hope that she might be allowed to keep them on for her caning. But then he pulls them slowly down to fully expose her buttocks for punishment. Now her humiliation is matched by her increased dread of the pain, knowing that she will not have her knickers to give her bottom any protection during the thrashing.
The caning is methodical and hard from the first stroke. The aim is to raise a stinging welt across her buttocks each time and then, once her bottom is fully striped, the caning continues even more painfully across the existing marks, despite any crying and promises to be good that the girl will likely offer.
Once the teacher is satisfied that the girl has been thoroughly punished, she is made to stand, while she is still crying, where other girls will see her, holding her skirt up and with her knickers down, displaying her thrashed bottom as an example of how the school deals with misbehaviour.
