J×J 女子校生獣化計画 ～メス○公開生調教～

Mammoth Academy in the metropolitan area. After the health checkup at the Academy, three schoolgirls were called for re-examination.
There, they are told that something is abnormal in their brain, and coerced to masturbate for examination.
"It's only a medical practice" said a female doctor to obeying crying girls. Afterwards, was a harsh verdict for them:

"There is an abnormality after all. You need the "specialized" therapy."

In this way, it was decided that each girl will be treated by "Animal-assisted therapy (AAT)".
Animal-assisted therapy is a common psychiatric practice. It was something entirely different for these girls, however...

"Bestial claws that dig into a soft skin that was always pure."
"Bestial juices that are poured in genitals and mouth."
"And finally, a bestial penis that pierces inside."

Their purity and chastity are completely defiled by the beasts.
Close people around them kindly admonish the girls who were trying to refuse this abnormal therapy:

"It's to treat your disease."

But that was all a part of dreadful project to “Bestialize” all three of them.
