After a teacher and a student share a meal, they both get an acute case of food poisoning. The need for a restroom is urgent but the toilet is occupied. The female teacher collapses on the staircase after looking for another restroom and shits her panties, forcing her to change and wipe herself when she finds a toilet.
The student does not even make it out of class and has to endure the humiliation of a fellow classmate helping her change out of her soiled panties.
History tends to repeat itself and they both have to suffer this fate twice.
