Research has revealed that a newly discovered unknown virus mainly enters the human body through the anal mucosa. In order to develop a vaccine as soon as possible and prevent the spread of infection, it has become necessary to analyze a large number of anal passages, so "anal health examinations" will be conducted in schools across the country. This examination will be conducted in strict secrecy, and even if some human rights are ignored, we will tolerate it to a certain extent. We would like all students to obediently follow the instructions of the doctor and nurse, take off your panties, and get on all fours on the examination table with your anus open.
