Principal Abacus Cinch, in an ill-advised attempt to stop smoking and sexual acts into the school’s bathrooms, has decided to lock down the lavatories, in hope to completely remove- or at least heavily discourage- the aforementioned behaviours from happening on the school grounds.

In short, Principal Cinch does not know what she is getting into.

Contains (a bit tastelessly) some omorashi. Also, diapers just up ahead.
