tease Dark magician girl, while studying

Dark magician girl is happy to see you, while studying in the library. But after accidentally seeing her white panties, you couldn´t resist and play with her pussy while she is beeing on the ladder. Dark magician Girl is not happy, but in response a deal is made. She gets a book for her favorite spell, which she is looking for a long time now. The spell worked and she is happy, but just for a moment. That´s because the other side of the deal means that you can tease an fuck her from now on as much as you like <3 Unfortunately, after cumming many times inside her, you also damaged the book...
