Is He Trustworthy? (BillDip)

Dipper (17) has finally gotten over the worst of his nightmares of Weirdmaggedon. He still has them, but they have gotten better over time. Until a certain dorito starts to talk back in his dreams. Bill has been living in his dreams for about 4 months. They aren't freinds, but they aren't enemies anymore.

Should Dipper trust him? He doesn't know. Him and Mabel return to Gravity Falls this summer. Nobody knows about Bill's dream visits. Yet. Bill wants Dipper to free him when they return. Dipper, will you trust me?

I hope that was a good description. This is my first ever story. I'm thirteen, so don't expect much from me. I want to make it good, but I don't know how to write smut yet. I am going to try, but it will not be good at all. Schools also in for me at the time that I'm writing this, so I might not update this much.
