To study men's bodies, the rich and famous female college students of a certain famous university run out of school and call out to men who seem to be virgins in front of train stations and shopping centers, capture them in their cars, and then gather around them to perform a physical examination! They used their own bodies to test the sensitivity, erection angle, expansion rate, and ejaculation time of the penis. Even though they say it's research, the female college students can't hide their excitement.
