Studies have shown that the newly discovered unknown virus invades the human body primarily through the mucous membrane of the anus. Since it became necessary to analyze a large amount of anal in order to develop a vaccine as soon as possible and prevent the spread of infection, "anal health examination" will be conducted at schools nationwide. This medical examination is confidential, and even if some human rights are ignored, it will be tolerated to some extent. Please obediently follow the instructions of doctors and nurses, take off your panties, open your anus on the examination table, and crawl on all fours.
