If that is Belinda Lawson he should have caned her much, much harder and much, much longer as that girl can really take it as she's shown in other films.
Nice video, but all thoroughly forbidden in the UK\; even befoe physical punishment was banned in all educational institutes the late 90s, it was forbidden for a male to administer to a female, and never was underwear rremoved. In fact it was rare for the cane to be applied anywear other than on the skirt or trousers: this applied to male and female.
Yes, a good, hard caning would have made all the difference. As you say, she is in a good position and with such a lovely bare bum begging to be properly caned it's a shame he does little more than play 'pat-a-cake' with her.
Yeah the slipper is not a good spanking tool. I received it a few times and it was not as sore as a proper hand spanking or the sting of the hairbrush. I can't find School Slippering. The only good bits of this video are she is made to touch her toes, she counts the stokes and a few land on the painful part of the lower bottom.
Yes, in 'School Slippering' she is haughty and arrogant, and it is nice to humiliate and chastise a girl like this very severe with the cane on her bare ass, until she screams and is whimpering.
She may have been beaten by several teachers one after another, so she started to learn her lesson.
