I borrowed this image from the French site, Au fills de jour (for which many thanks) , and my goodness it does takes me back. Nothing in a third world prison can match the sheer sadism of a bunch of senior school girls when they've got it on for one of the group .
"Come on! Let me, it was my idea to pull her knickers down."
"It must be my turn, you've been spanking her for ages!"
“Wait till it’s my turn . I’ll show you all how it’s done!"
And later it will all be forgotten. Her bottom will be kissed better in the dormitory, and in due course the group will re-form and the victim will have her turn at being an oppressor.
It was ever thus!
