Nothing

Res had a fun idea. He put both students back under.

"Okay. Luna, get dressed. I need you both fully clothed for this."

Once both Romilda and Luna were redressed, Res got to work.

"Okay. Luna, be honest. On a scale of one to ten, one being hated it and ten being absolutely loved it, how much fid you enjoy being a dog?"

"Eleven."

That surprised Res. "Really? So you wouldn't mind being a dog?"

"Not at all," Luna said.

"And Romilda," Res said. "On the same scale, how did you like being a pig?"

Romilda blushed. "Seven. It was fun after a bit."

"Would you mind being a pig?"

"No, surprisingly."

"Okay. Here's what going to happen. Luna and Romilda. You both have secret identities as animals, that your parents have sealed away. Lovebitch and Pigmilda, respectively. You will thank me for freeing them, and will want them to be my pets. However, you will still attend classes as Luna and Romilda, but when your classes are over, you will seek me out and let Lovebitch and Pigmilda roam wild in your bodies to their heart's content. Understand?"

Both women nodded.
