Throw the wand

You throw the wand. It soars through the air slowly spinning as all of you hold your breath. It is almost beautiful as it glides towards its target.

Finally the librarian catches it and in one quick movement she points it towards the demon. Her eyes glow with supernatural energy as she quickly summons a void behind the demon.

The void is only the size of a pin head but never the less the demon is sucked through it and banished.

The librarian is still oozing thick cum from her holes as she start to approach you. "Thank you... If you need a book just go in and take one... I will be cleaning myself." You can't help but pause. Why was there even a demon here in the first place? Even so you decide to not ask and instead look at your mentor. "Where did you banish it to?" You finally ask. Your mentor seems surprised by your interest but her only response is "Just don't go to the girls bathroom in the next couple of days."

With that she leaves you alone in the library.
