First Impressions

This is a Gravity Falls fanfic sporting a few AU's I've read recently. The Pines brothers are all triplets and Mabel is there older sister by a few minutes. Dipper, Mason, and Tyrone Pines all are going to the Gravity Falls High School. They are all seniors, and 17. Bill, Will, and Kill Cipher all find that they are attracted to the Pines brothers. What will happen?

I own NOTHING from Gravity falls, this was all fan made. All rights go to their respective owners.
