Make a choice Dean
A/N: Story begins in the middle of a hunt.
Dean x Sister!Reader Sam x Sister!Reader
You and Sam looked around the hallway you were standing in; there was nothing special about it. Just a hallway of what appeared to be an empty factory. Glancing over at Sam, you nodded at each other, silently communicating that you should move.
The two of you were looking for Dean who had been taken by the djinn who fed off of fear. Sam had killed it a day ago but Dean never woke up, which led to where you are now; walking in Dean’s nightmare, trying to find him so that he could wake himself up.
You had just turned the corner when you heard a voice chuckling from what sounded below you. Sam heard it too because he glanced at you before walking to the railing to view what was going on below you.
Your eyes widened as you took in the scene; the dream’s version of you and Sam were each tied to a chair while Dean stood five feet in front of you. A man, a demon with black eyes showing, stood off to the side a few feet away.
“The hell?” You heard Sam say next to you.
“What is going-” You began but stopped when you heard the demon begin to speak.
“Alright Dean, choose. Do you want to save your brother, the one you raised and spent your entire life looking after.” The demon paused, “Or your little half sister who you didn’t even know about until the apocalypse? Your choice.” He said while handing Dean a gun, “You better choose quickly, otherwise I might just kill them both.”
