A group of doctors thoroughly examine a schoolgirl's development, even measuring the number of wrinkles on her anal opening! As part of a special investigation project taking place within a certain district, two popular JK idols arrive at the Magic Mirror car interior studio. They agree to participate in exchange for better grades... but they end up embarrassed when one of them has an accident during their internal examination. Despite trying to cover for each other, both girls become aroused by the attention and end up moaning in pleasure while being fondled. Meanwhile, a sneaky male student takes advantage of the situation, secretly masturbating among the crowd. Even though he's about to have a mental breakdown due to public exposure, the examination isn't even halfway done yet! The girls are taken turns being penetrated by the doctor's huge cocks, reaching multiple orgasms together while holding hands.
