The anime itself depicts teen-aged (and well endowed) school girls getting raped—by her teachers (the first episode), by some "businessmen" who mistake the girl for a hooker (the second episode), by a class mate in mad love with the girl (third episode), and finally two sisters being raped by the school janitor.
