"The girls' dormitory"... a secret garden where only women live, where men are not allowed. This film sets up cameras in each room of this forbidden girls' dormitory to peek into their daily lives. There are students sharing a room with their seniors, and students having fun engaging in dirty talk in the living room. They each satisfy their sexual desires in the limited space and time they have. The thrilling masturbation stories, which take place in the common space late at night, under the covers, seem to make their private parts even wetter. They press their ears against the wall, worried about their friend moaning on the other side of the thin wall, but they can't stop moving their fingers.
