Many of the stories will have the ring of truth and many ARE undoubtedly true, but you’ll soon spot the porkie pie merchants.
In the hands of a ‘good’ tall story teller, your tale would have ended with the girls (both of whom were remarkably attractive) being sent to wait outside the office while you were dealt with by Deputy Head. The girls would have heard you being caned, much to your embarrassment.
A more adventurous writer would have had you caned while the girls watched, and a top-notch fantasist would have you caned BARE while the girls watched.
But, if you want solid-gold, diamond-studded, creme de la creme fantasy writing . . . you would have been caned bare in the girls’ presence and as the caning proceeded you would have looked through your bare legs and seen one of the girls apparently scratching some sort of itch.
Hopefully, the above will guide you when submitting further accounts of your CP experiences
