That season has come again... the season of shame. Physical examinations are conducted with the cooperation of the prefecture and the university hospital. General and specialized examinations are carried out, including internal medical measurements, electrocardiograms, and tests for sexually transmitted diseases and breast cancer. All examinations are conducted with both men and women, and the results are stored and used as research data. Also included is sex with five girls, who are teased by doctors and students, and have their innocent slits stretched wide.
