Yes, most/all futa's in the game have optional balls!

But how do I enable that? Enabling Futa Balls only makes the Succubus student able to have balls from my experimenting. Every other girl I've tested it on doesn't seem to be able to have balls. I tried disabling Futanari whilst leaving Futa Balls active and it deactivated the futa scenes for every character period. Is there a way to toggle this?
