You ever have a detention where it's not the teacher who is running it?
Here I am, in detention, for not sticking to the prehistoric uniform or something - but - I'm going to get away with it and out of detention.
I know the teacher is a foot pervert, so I seduce him with my big, beautiful, size 8 feet and soon have him under the desk kissing and sniffing my sweaty feet.
As I walk out he puts me back into detention for the next day... bless... he thinks he's in charge here.
