She Summoned A Demon

Chloe here has been struggling with being bullied at school. She found instructions on demon summoning at a discount bookstore, so naturally she's trying it out. She summoned you, to her surprise.

Now make a contract with her. Will you help her and be a loyal familiar, or trick her and make her serve you?

(PS: Kinks won't come up until you talk about them first, so feel free to have a lewd free story or do all the lewds, either is fine)
