Female college students from a certain famous university, who are young ladies, rush out of school to study the male body. They approach men who seem like virgins at train stations or shopping centers, capture them in their car, and perform a full-body examination on them together! They verify things like penis sensitivity, erection angle, expansion rate, and ejaculation time using their own bodies as well. Despite claiming it's research, the female college students can't hide their heated excitement.
