The headmistress liked to discipline with the cane because she got excellent results with this method. No matter how stubborn the pupil was, she would eventually absorb the lesson, provided she was spanked often harshly enough in the bare ass with the cane.
The buttocks muscles twitched uncontrollably, but nothing could stop the pain of the correction. The cane relentlessly cut the teenager's buttocks, increasing her torment. It took enormous self-control to remain still and endure the strokes of the cane without jumping up in pain.
For me, such canings, over school skirts or knickers, are far more nostalgically rewarding than the fantasy bare bottoms ones which the internet is awash with today. If not on their hands, which was by far the norm, this is how girls were caned at school.
