Some years ago I remember talking to a fellow CP enthusiast who claimed that at school he had once been sentenced to 24 strokes of the cane, given in four sets of six over consecutive days, meaning that he had to go back to be caned for the same offence four days running.
Also,I once swapped a couple of emails with someone chatting about our schooldays experience of cp and he told me about such an incident. What he told me could have been the exact truth, a story based on truth or just one of his fantasies, there is no way to know for certain.
