[read description before reading!!] bound to you ; bill cipher x reader

the deal

Stanford, Dipper and Mabel were in the air, blue glowing chains tightly wrapped around their necks. Your eyes were wide and you looked shocked at them until your gaze wandered over to Bill. His body was engulfed by blue flames and his eye was glowing red with a bit of gold in it. The chains around the pines' neck were connected to his back.

"B-bill...", you mumbled.

'How am I supposed to calm him down now...?'

"Doll~", you heard Bill call out and your eyes met his red one while an insane grin appeared on his lips.

"Don't worry, I'll take them out of our way~", he said and chuckled afterwards. Than he looked at the Pines, his grin getting wider, if that was even possible.

"S-see, (Y/n)...y-your dear friend is a monster!", Dipper cocked out, clawing at the chain and trying to get rid of it. You looked at the three of them, than back at Bill. You didn't want to believe that he was a monster.

"(Y/n), you have to shoot him down! That's the only way!", Ford yelled, also struggling against the chains.

You didn't know what to do. Save your friends or save the demon or all four of them. And how were you even going to do that? You looked between them all while starting to panick.
You felt horrible. You were scared, sad, angry. Your whole body started trembling and tears welled up in your eyes. You made a fist and looked at the ground.
Suddenly, you felt two arms wrap around you. A warm body leaned against your own and the arms wrapped carefully around your stomach. You looked behind you to see Bill hugging you very carefully, like you were a broken doll and he was afraid to hurt you even more.

Bill raised his left hand and interwinded it with yours.

"I want you to be all mine, (Y/n)". A sudden heat went through your body. He placed one of his hands on top of your left hand. A little, (f/c) triangle symbol appeared on your hand. Your eyes widdened and you stared at the symbol.

"You are mine"

"And in return you are bound to me. Does that mean-"

"What!? Why would you make such a deal with him, (Y/n)!?", you heard Dipper yell, now sounding even more shocked. Than Mabel spoke up as well:

"Are you insane!? Why would you do that!?". You weren't really listening to them. All you did at that moment was staring at the symbol on your hand.

"Bill", you finally decided to speak up. He flashed you a smirk.

"I want you to set them free and destroy their weapon", you said, sounding determinded. Bill obeyed your order with a grin. The chains dissapeared and the pines fell to the ground. Than their weapon got destroyed as well. Bill's looking changed to a more or less normal one. His clothes were mostly torn apart, his hair was messy and he had blood here and there. The blue flames left his body as well and he sat on the ground, breathing heavily. You looked at him and than at the Pines, who were all starring at you in shock.

"I apologize for the mess", you said and bowed your head slightly.

"I will take my...my demon and my things and than leave this house immediately. I am horribly sorry for causing so much trouble. But please give us a few minutes to leave". You than helped Bill stand up and led him to the room the Pines gave you. Fortunately, you didn't had to pack all that much since you haven't had any time to unpack as well. All you wanted to do was clean Bill up, talk with him and leave. When you opened the door of the room you made Bill sit down on the couch bed and closed the door behind you.
