You glare at Lillian and tug at the book. Lillian tugs back. "Let go. I need this book for class!"

"Well, so do I, so you let go!"

"It's mine you little slut"

"Look, you brainless bimbo..."

The conversation goes downhill from there. You don't notice the volume going up at the same time, at least not until Lillian suddenly vanishes and you suddenly see one of the librarians in her place, with a Lillian sized belly on her. Before you can even digest this, you see a large circle of blackness and then nothing at all as you feel yourself sliding rapidly down her throat and into her belly where you collide with Lillian. A moment later the two of you are thoroly tangled up with each other.

The librarian rapidly marches somewhere, bouncing the two of you around, against, over, and under in a manner that proves surprisingly erotic. You are more disappointed than you want to admit when she soon comes to a stop. "You young ladies have been told you are not to make noise in the library, have you not?"

You have not been a bad girl, at least not exactly, but you have had chances to learn one should appear contrite in such cases, at least while they have you dead to rights. "Yes, Ma,am. I'm sorry. I just got angry because she wouldn't give me my book."

Lillian of course has a different idea of who the book belongs to, and the librarian doesn't care. "In the future, you are to settle such disputes between yourselves, and without making a racket. Since you are new students, I will cut you some slack. Normally I would confiscate the book, if I was in a good mood, and have you for lunch, if in a bad. However, I will give you some advice instead."

"Thank you" you manage. You wonder whether you wouldn't really rather do without book and lesson, but..."

"Now the simple way to handle such disputes is just to eat the other girl. That's not entirely approved behavior around here. We are here to teach you to restrain your appetite, not to use it at any excuse. But you will find a lot of fights are settled that way.
"Better is to just come to some agreement. Now you both want to use this book? A plan that often works is that you flip a coin. Winner eats the loser and studies the book, reading out loud so the girl inside can study too. Then you switch positions when the first girl gets out. The 2nd girl eats the first and starts reading out loud. That sound good to you?" You don't try to object. "Good. I'll spit you out and then watch the coin flip. Then the two of you can be off to the winner's room to study."

A moment later you are deposited on the floor. Then the librarian is handing you a coin, which you flip and tell Lillian to call. She goes for heads and the coin comes down...
