At an earlier desk inspection, Miss Cate McQueen and Mx Valleycat found porn in one of the student’s desks! 
Firstly, starting by humiliating him for the poor choice of porn, there does need to be a formal punishment.
Dirty boys who read porn receive punishments.
There is a punishment bench in the class, his pants are down, and ass is out.
Mx Valleycat and Miss Cate start with a bare hand spanking. But that isn’t going to be enough.
So, the cane comes out. Unfortunately, this boy can’t go home marked as his parents will complain – so – persistence is the name of the punishment, and he is given 40 constant strikes, often over the same position.
Another student is caught giggling during this punishment, so he is pulled over as well to be given a spanking.
