The world is fucked up currently, and a ton of futanari women decided now was the ample time to take over and begin a matriarchy. Now every "male" is required to go into these HRT institutes to be trained to be fit for society's new standards. Also regular women are also to be sent here so they can become beautiful futa's just like their superiors. I'm sure having both sissies and futa's in one place won't go well~
