Imagine you being possessed, and Dean doesn’t realize it at first
It seemed like these days, there were demons everywhere. Most of the cases you and the boys went on were demons. This case was the same. It was two towns over from the bunker, so you three were going to crash and dash their little chaos party they have going on. Sam estimated five altogether, so while being outnumbered, you three hoped the element of surprise would be on your side.
While in the backseat, you were reading a new book that Dean had picked up for you not too long ago. While you were focused on your book, Dean was focused on you. He admired how your face would change when something happened in the book, how you looked cute when you were concentrating, and how, most of the time, you had a little grin that he thought was the most adorable thing in the world. His eyes fought between concentrating on the road and concentrating on you. He never expected to fall for you, but slowly, the three of you working together over the years, you found a way into his heart. You were his best friend, and you knew almost everything about him. You accepted him, flaws and all. While he wanted to pursue more and be the one to call you his, he didn’t want to mess up what the two of you already shared. So, he would wear his best friend's title with honor and ignore the feeling he got when another guy would come around. He would pretend like he wasn’t happy when they left as well.
You, on the other hand, have loved Dean Winchester since you first met. The way his green eyes looked over you, concerned and impressed when they first met you. The first time he called you sweetheart, and over the years, the pet name princess he settled for would make your heart skip a beat every time. He would grab your hand in sticky situations to keep you close and make your face turn red at the worst time, and how he tended to you so carefully after each hunt. You have loved this man for years, but he never made a move, so you wore your best friend’s title with pride and tried not to compare yourself to the women he would pick up at the bar or try to feel that glimmer of hope when he does something that doesn’t seem entirely platonic.
The three of you came to the back of the house where the demons stayed. From the window, it looked like most of them were downstairs. Dean made the plan that he and Sammy would take the downstairs with most of them, and you would head upstairs to gank any others. When you and Dean nodded, Sam kicked the door down, and the three of you rushed in.
Upstairs, you have cleared most of the rooms. You can still hear the two boys downstairs fighting, so you are trying to be quick. You open one bedroom door and step in at first, not seeing anything, and then you get hit from behind. Two men grab you, and a woman steps forward from the dark corner of the room with black eyes. There is way more than what Sammy had initially thought.
“Hmm, you seemed to have ruined my little party.” The demon faked pouted. You looked up at her with hate in your eyes.
“Go to hell.” You replied. She bent down to your level.
“Baby, I’ve been there and don’t plan on returning.” She stood back up, and one of the men looked like they were about to hit you in the head.
“Stop!” She said suddenly. The man stopped. “I think I have a better idea.” Black smoke came out of the woman and headed directly to you. Panic struck you as the smoke entered you and down your throat. You now regret not going to get an anti-possession tattoo with the boys. She was now inside your body, and you were screaming and fighting to get out. The men let you go. She turned to them.
“Get out of here unless you want the Winchesters to kill you for touching their little trophy girl. I’ll catch up to you another time.” The men nodded, and then black smoke exited the two bodies, making them drop to the floor. The demon went and stabbed each body with your demon knife, making it look like you killed them. You are screaming the entire time to stop. She looks at you in the mirror.
“Hmm, we need a little more convincing.” She takes a different knife and cuts one of your arms, your cheek, and then cuts from your eyebrow up. She makes the one starting at your eyebrow a little deeper, and she or you hiss in pain. That cut will probably need stitches.
“Princess!” You hear Dean yell as feet are pounding up the stairs. The demon smirks in your body.
“Show time, Y/N.” She snickers and then changes her face to one of fake exhaustion.
“Dean! I’m here!” You yell. You turn and run towards the door and meet Dean at the entranceway. He immediately grabs your face and looks at the gash on your head, worry clouding in his eyes. His eyes dart behind you, and see the three bodies on the floor.
“You had to take on three of them?” He said, worry and guilt laced in his question. You nod your head.
“I’m so sorry, princess; I should have come up here with you.”
“I’m okay; I took care of it.” You speak. Sam looks behind you.
“I’m sorry, Y/N; I should have known there were more.” You turn to Sam.
“It’s okay, Sammy.” You say. You look back at Dean.
“Can we go home?” You ask, the demon trying to do your little puppy face that you learned from Sam. He nods.
“Yeah, we will go home and patch you up.” The three of you start to leave. Meanwhile, you’re screaming from inside your head, trying desperately to take control just for a few seconds.
Back at the bunker, Dean patches your cut on your face up, careful with the stitches, eyes only leaving his work temporarily to look at you. You sit there, the demon doing her best not to give off any signs that you aren’t you.
“All done, " he says. His eyes lock onto yours, and you try to scream to him that you are not him. You take his face in your hand, and he closes his eyes and leans into it.
“Thank you, Dean.” You say softly. He looks at you.
“I should have gone with you.”
“It’s okay; I’m a big girl; I took care of them.”
“Yeah, but you got hurt.”
“You patched me up; I feel as good as new.” You smile at him. He smiles and leans over, and kisses your forehead.
“I’m glad, princess; I’m going to take a shower.” You nod your head and watch him leave. As soon as he is gone, you roll your eyes and scoff.
“You two are disgusting.” The demon says in disgust to you. You are cussing her out seven ways from Sunday, but she laughs.
“Your little Dean is so smitten with you; he has no idea something is wrong with you; he is just glad his precious little Y/N is okay.” The demon makes you giggle and then gets up. She catches sight of you in the mirror and turns her eyes black.
“This is going to be so fun.”
A week. You have been trapped in your body for a week, and neither of the boys have noticed. You have stopped fighting. It's heartbreaking that the boys can’t pick up on the fact that you haven’t been in your reading corner for a week while they do research, you haven’t cooked in a week, you haven’t gone into Dean’s room in the middle of the night, or you haven’t joined Sam in for a workout. The demon has made you more flirty with Dean, which makes you sick as it’s not you, but more that Dean is giving into it and flirting back. While you would love to be on the receiving end of the flirting, it’s not you.
Without your or the demon's knowledge. The boys have noticed a change in you. They talk about it quietly while you’re not around and share glances when you do something you wouldn’t normally do or say in front of them. At first, they thought you were shaken up from having to fight three-on-one at the house, so they let you cope, but now they suspect something else is happening with you. Dean’s heart clenches whenever you make a flirty comment to you, wishing he could believe it was you saying these things to you, but that isn’t like you to be so bold in coming onto someone. He plays along to make what he thinks is a demon in you not suspicious, but also, he can briefly believe you return his sentiment.
You just came back from the bunker, talking to the two demons who were at the house. They are planning their next move, and the demon has big plans for your body and getting the Winchester brothers. Dean is sitting in his usual spot across the library, and Sam is walking in from the bedrooms.
“Hey, princess,” Dean says, looking up at you coming down the stairs.
“Hey, handsome, miss me?” You say, smiling, flirting with him. You make your way across the library.
“Always beautiful.” He flirts back with you. You go to step to him when you can’t move. You look confused.
“What?” You say. You look around, and Dean gets up and moves the corner of the rug to show part of a devil’s trap. This grabs your attention inside your mind. The demon inside you makes your face twist into anger.
“What gave me away?” You sneer at Dean.
“Few things.” Dean cocks back at you with an attitude, hate showing in his face. While you know it's not directed at you; it still hurts you a little to see him looking at your body like that.
“Firstly,” Sam starts, “Y/N always joins me in the morning for a little bit of a workout, even if it’s just fifteen minutes to get her body going for the day. She also always goes to that little corner while Dean and I are researching; she never joins in as that is the quietest time in the bunker to get a few chapters in her book done.” Sam points to the corner when your reading nook is set up that hasn’t been touched in a week.
“Next, Y/N always cooks meals while we are here; it’s something that makes her feel like she is helping since she doesn’t research, even if it is just something small and easy.” Dean continues. “She also always comes into my room in the middle of the night. She hasn’t been in her room for a whole week in a long time. Also, Y/N is never as flirty as you have been. She has never been that direct with any man, let alone her best friend. She would never say those things to me.” Dean snarks at you, jaw clenched, eyes hard.
You laugh. “Oh, Dean,” You start. You are yelling inside your mind for the demon to shut up. “Poor little Y/N was fighting for a good while to try to get to you, but she gave up.” You say darkly. “She couldn’t bear the thought that you and little Sammy couldn’t tell it wasn’t her and making her stay trapped inside her own body, so she gave up fighting. Her little heartbreaking that you two were so comfortable with me around.” Dean faltered slightly, but his eyes got hard again; Sam stood beside him, glaring at you.
“You should hear some of the things Y/N thinks about her best friend, Dean. This girl is head over heels in love with you, and it was making her so sad that you liked me better than her; flirting with me, holding me, she just wished it was her. Y/N doesn’t think you could ever love someone like her, as she is not who you usually go for, but we know better, little Dean. You are so in love with her; you couldn’t even tell the first night you brought her back; you were just so thrilled that she was being a little more handsy with you.”
“You bitch.” Dean sneers at you. Sam and Dean grab you and tie you up to a chair. Once you are tied, Dean leans over you, getting very close to you or the demon.
“You’re going to get out of her and go back to hell where you belong,” Dean says darkly. You smile.
“Careful, Dean, you’ll turn her on being so close.” Dean goes to slap you but has to stop himself, reminding himself that you are still in there and he doesn’t want to hurt you.
“Oh, you were going to hit me? Kinky Dean.” You reply seductively, trying to get a rise out of him.
“Fuck you.” He spits as Sam finds the book with the exorcism in it. Sam starts reading it, and your body starts to twitch. You look at Dean glaring.
“You know she wanted to die all week? She kept thinking about how she would rather die than have me in her body any longer. She would beg you to notice and do something, but you never did.”
“Shut up!” Dean yelled at you as Sam continued reading. The demon was gripping to stay onto you, but you could tell she was losing. You were able to take control.
“Ugh, get out of my body! Sammy, hurry up!” You yelled as your body was jerking around.
“Princess, fight it!” Dean said, getting close to you and grabbing your arms. You look at him with tears in your eyes. Then your head leans back, and the black smoke comes spilling out of your mouth before disappearing to hell, where the demon belongs. You close your eyes, breathing heavily, and little tears come down your face as the boys untie you. Dean helps you up and guides you to the couch while Sam grabs you some water. You roll your head to the side and peek your eyes open to see Dean already looking at you.
“I know that face; it’s not your fault.” You say before he has a chance to let a word out.
“I should have noticed sooner, " he responds, his hands rubbing against yours. Sam brings you the water, and you take a sip.
“I’m so sorry, Y/N,” Sam says. You look at Sam.
“It’s not your fault, Sammy.” You say. “I’m just glad the bitch is out of me.” Sam looks at you worried.
“Was it telling the truth, Y/N? Did you want to die?” Sam asks quietly. You sigh and look at him, trying to decide how to handle the situation.
“I wanted to,” you said softly. Being able to watch what you're doing but not able to control it is the most exhausting and frustrating thing. I did things that I couldn’t stop myself from doing, and I will have to live with them for the rest of my life.” You look between the two brothers.
“But you two saved me and got me out; that’s all I can be grateful for.” You give them a small smile, and Dean looks at Sam with a pointed look. Sam gets the hint and excuses himself. Dean looks back at you.
“Was the demon lying about the other things too?” He asks quietly after a few moments of silence. Your breath hitched in your throat. You looked at him, and his eyes scanned your face, trying to figure out what you would say before you said it.
“No, it was the truth.” You finally say your heart is beating fast while looking at the other brother. Dean wastes no time leaning over and crashing his lips onto yours. He grabs your face in his hands while you drop the water bottle Sam gave you and guides your hands to his hair. You two pull away after a few moments, foreheads touching, eyes closed.
“I’ve loved you for a very long time, Dean. I never wanted to mess our friendship up, so I didn’t know how to tell you.” You whisper to him. Your eyes open to his green ones, and a smile plays at his lips.
“I love you, Princess, and I’m going to spend the rest of my life making up for lost time.” You smile as he pulls you into another kiss. Maybe that demon was helpful for something, but you will never admit that to anyone else.
