Ah, Schoolgirls, so innocent, yet so delicious.
Good Girls should always endeavour to please Sir (or Madam), obeying all instructions at all times. Good Girls spread legs and suck cock without question, ever obedient.
Obedience is the essence of a Good Girl.
Bad Girls must be dealt with severely; they must bend over and then be severely spanked and caned and paddled, until the girl's bottom is bright red and sore.
If the bad girl still misbehaves, then she will be fitted with a collar and leash, and her panties should be removed and stuffed into her overactive mouth.
A useful function for Bad Girls is as the "School Slut", offered to the boys to satisfy their male lusts. The girl's humiliation must be total.
This girl has been very naughty...how should she be "corrected"?
