Bill cipher x reader

Dancing with demons

After your little 'house sitting' incident it was hard to keep secret the fact you were friends with bill (and a bit more).
This changed everything,especially after the pines family learned of his true plans one day. and unwittingly so did you.
"Bill!!!! Get your friggin demon ass out here!!!!" You called out to him as you stood in the middle of the creepy part of the woods. Usually he could hear you in the dreamscape and would appear if need be.
"Yes, ___?" Bill appeared beside you in his usual triangle form.
"WHY DIDNT YOU TELL ME YOU WERE GONNA CAUSE THE APOCALYPSE AND TAKE OVER THE WORLD?!" You scolded gripping him and shaking him a bit. 'Bill emotions were clear as day' he was not expecting you to find out. He transformed into his human appearance standing before you.
"I never expected you to find out...." He smirked. "It's a pre-destined fate of mine but don't worry I'll leave you safe as well as the pines. they're fun to mess with."
"I'll make a another deal with you..." you looked at him determined. He raised a brow.
"Oh? And this time?"
"Anything I can give you to stop you from causing that..."
"Hm... good offer." bill smirked at you "alright. my terms are, you must become immortal."
What bill didn't understand is that is one of the things you actually wanted.
"Deal." you took his hand as it glowed with blue flame. At the same moment you leaned up kissing him.
For a while the two of you were lost in the kiss before you had to break for air.
"Oh and to addition. To immortality you must stay with me." bill smirked wrapping a hand around your waist.
"Heh. alright. guess making deals with you is better than I thought it would originally be.~"
(Sorry it's short. but hey! Update :D)
