Dipper and Mabel are turning 21 and are back in Gravity Falls, but everything seems to change when Bill finds Dipper and turns to tormenting his mind any chance he gets, giving him horrific hallucinations, nightmares and teasing him, always touching him. Unable to decide if he wants wants to kill Dipper (For reasons explained way later) or if he wants to have Dipper, body and soul ;) In this particular story I've changed up the story a little bit. Mabel, and Dipper have not actually met Bill... In this lifetime anyway. They still solved mysteries when they were younger as Mabel refers to their old "Mystery Twins" Nickname once. (Stan and Ford know Bill, just as they had in the show but i don't really touch on that just an FYI) None of the artwork is mine, full credit to the artists!! Definitely Rated R, strong language, sexual scenes and smut later, torture, nightmare/horror scenes so I'm assuming it's probably (Definitely) got some triggers. Enjoy at you're own peril!!!!

Billdip Siren\Pirate AU Dipper and Mabel we're sold to pirates as slaves when they were 16. They are taken in by the owners of a ship called, Mysteries Of The Depths. The ship's captain, a man named Ford, was fascinated with mystical creatures. So he goes off on his own to look for creatures himself, after a dispute between him and the ships second in command, Stan. It's been two years, and Ford still hasn't returned... Somehow this got #1 Billdip Idk how that happened honestly ART IS NOT MINE. ALL ART IS CREDITED IN THE LAST CHAPTER. ALSO SHOW/CHARACTERS ARE NOT MINE. While I am aware that the characters here are different than the ones in the show, they still are not my original characters. All characters belong to Alex Hirsh and the Gravity Falls team.

This basically is going to be about sex for Billdip

It's Dipper's and Mabel's third summer in Gravity Falls, but things don't go as smoothly as their second one. Weirdmaggedon has started all over again ; much worse than before. There are more hench-maniacs, more terror - more deaths. And when Dipper gets taken by Bill, everything changes drastically. Why does Dipper feel like he's growing fond of the demon? What happened to Mabel's optimistic world? Will Both siblings be able to fix their past in hopes of a better future? Or will it all crumble down in flames? Adopted from @GravityFallsFreak7 Mild cursing, smut references, violence.

"A warning to the people The Good and The Evil This is WAR To the Soldier The Civilian The Martyr The Victim It's the moment of Truth and Lies The moment to Live and Die The moment to FIGHT?" The things you said to me, that this will keep me safe if I just listened. They were all just lies from the start. All of them. Do you know how it feels like to be stabbed in the back. Of course you don't. Why bother asking? Being stabbed repeatedly and then being asked if you're okay? Blood running down your back, then being stabbed again after being asked that question? That's all you can do I trusted you, I protected you, I almost gave up my life for you! This is all you can do, Just use me like you always do. NOT ANYMORE I've learned a few new TRICKS Are you proud of me? I hope you are. You're the reason why I blocked out all emotions from the world. The reason you think I'm still happy when I'm not. The reason why I'm here. You don't remember him don't you? He's still apart of me, but not you. You MADE me like! That's was so much fun. Making sure I was always ripped apart while you're stood in one piece. The promises you've broken, The judgement no one bothered to tell you, The so called friends you have. It's all over now.I've covered for you long enough, all those years ago when I was still sane. I'll pretend to be happy for you, I'll pretend to be your good old pal. Oh I will. I'll just show you all those pretty little white lies that you LOVE so much. I'll sprinkle them on top of you, I'll show you how much pain you've caused me. I'll bring them all back! Of course I'll be in your shadows, I'm always in there. Being mistreated and abused for you, of course! I'll make sure to add in some cuts and bruises for ya. I'll be your fucking shadow alright, I'll be it and make sure you fly close to the sun. You're afriad of the dark. You shouldn't be sweetie. You shouldn't be afraid of the dark, You should be afriad what's in it.

It's been ten long years sense the demon known as Bill Cipher took over the small town Gravity Falls. Dipper Pines and his sister Mable Pines are back for the summer. Dipper longed for something....Someone. A deal will be made to get what he wants. Will his family accept his choice? •Completed• {Edited}

For centuries people have believed in gods for certain things. They aren't perfect with their skills, so, they learn at a very young age. High school for Gods, goddess, and other creatures from that realm. Dipper and Mabel were transferred to Gravity Falls to go to the school there. Stan and Ford were taking care of the two. Dipper God of the Stars, while Mabel goddess of everything or mainly the emotion of joy/happiness. Bill is the God of the Sun and his brother is the God of the Moon. They're highly respected because of their nature or athleticness in the school. What happens when the sun meets a star? Can things end up good or bad?

It's Dipper and Mabel's third summer in Gravity Falls, but things don't go as smoothly as their second one. Weirdmaggedon has started all over again ; much worse than before. There are more hench-maniacs, more terror - more deaths. And when Dipper gets taken by Bill, will he finally get some answers? Like, how is Bill alive? Or, why is he creating another Weirdmaggedon? He has questions for himself. When should he go home? Should he try to stop Bill on his own? Why does he feel like he's... growing fond of the demon? Other Info : Dipper and Mabel are 14, turning 15 (in case you can't do math). There's a two year time skip at one point, so they'll actually be 16, turning 17 for the majority. The twins have grown up, so they don't do as much stupid stuff. And, yes. This is a Billdip. If you don't like, you don't read, ok? Good. Minor cursing : cr*p being worst. Occasional blasphemy. Ok! Enjoy the book!

Dipper makes a deal with a certain dream demon and things don't go quite as expected... SENSITIVE TOPICS INCLUDING: Non-Con Basically sorta Stockholm syndrome Smut S M U T

Twenty year-old Dipper Pines has returned to Gravity Falls. No Stan, no Ford, no Mabel. Just Dipper, Wendy, and Soos to take care of the Mystery Shack. One day, Dipper gets an ominous warning: a deadly assassin had been set upon him. Now Dipper must turn to the only one who can fight such a demon: a demon. Bill promises to protect Dipper, but who can trust a demon? My first BillDip story! Thanks to ShiningInsanity for giving me the idea while reading her BillDip stories. Time to get our OTP on! All Gravity Fall characters do not belong to me. All other characters do. Please don't use them without my permission. Also I use a bunch of scenes from other BillDip books, so keep an eye out for them!
