A global pharmaceutical company needed to collect rectal and anal data in adolescents for a trial of a new drug with innovative effects on rectal cancer. In return for a huge donation, the president of a co-ed school accepted to conduct an anal medical examination for the students. It is not hard to imagine that it will become sensational news when it comes out to the world. In order to do it more secretly, we decided to mix men and women and force the homeroom teacher to participate. For students, recommendation admission by raising the score is a carrot at the tip of the nose. To the female teacher, mind control was performed, saying "Be a model for the students as an educator", and thus a mixed male and female anal medical examination was to be performed.
