The Dark Side
@laphirablack asked: Heeey, can u do a fic with moc!dean x demon!reader, like she’s trying to convince him to go dark side. Maybe some hot smutty smut smurder??
Alright, demons are a go.
“So you want me to seduce your pet into going to the darkside?” (Y/N), one of Crowley’s most trusted spies had been asked to meet her King at a local demon bar.
“Essentially.” Crowley said, drinking his fruity drink through his straw. (Y/N) sighed, looking back at the bar tender and tapping her glass signalling him to refill it.
“What’s in it for me?” She asked. Crowley wasn’t cheap and the rewards from his little gigs were usually pretty good.
Crowley hummed, “The usual payment?” He asked. The usual payment was usually money and a higher position on Crowley’s list of friends.
“No way.” She said, “Don’t try to fool me. I know who this cat is. That’s Dean Winchester. The Dean Winchester, who will literally murder me on sight. I’m not going in there without a greater incentive.” She took a drink from her Jack and Coke.
“And what exactly would be a greater incentive.” He leaned forward.
“I want the usual. And I want you to get involved.” She spoke the last part quickly.
“I beg your pardon?” He asked, almost choking on his drink.
“They trust you. Sort of. You just talk to them with that sexy accent of yours and tell them that I am here to help them. Especially after that Ruby situation.” She grinned, crossing her legs.
Crowley tutted, looking her up and down, “I suppose you learned something.”
“Oh Fergus,” she placed her hand on top of his, “I learned from the very best.” She winked.
“Fine.” He said and smiled tightly. She hummed, looking down at herself.
“I suppose I’ll need a new wardrobe.” She looked at him expectantly.
He sighed, reaching into his pocket and pulling out his wallet. Handing her a few hundred dollars.
“Should be enough. All they wear is in the sporting goods department. Lots of flannel and jeans.” She grinned and stood, leaning down and pressing a kiss on his cheek.
The Winchesters had agreed to meet Crowley in the usual place. An abandoned warehouse covered in anti angel sigils.
“Alright, what’s this about?” Dean asked, he was opening and closing his hand on the arm that had the mark. The Mark always pained him and made him anxious.
“I don’t know. I just got a call from Crowley saying to meet him here.” Sam said, looking around.
“Hello boys.” Crowley appeared behind them with another woman behind him.
“Is that your trainee or something?” Dean asked, looked around Crowley at the woman.
“Hardly.” She said, stepping around him.
Crowley smiled, “Meet (Y/N). She’s going to be on call for me while I’m out on business. So don’t bother me unless she’s dead.”
Sam looked at her warily, “How do we know we can trust her?” (Y/N) hummed, stepping forward and unzipping her leather jacket. She pulled it open, revealing her bra.
Dean stared then tried very hard to avoid the merchandise. She pointed to the sigil on chest by her clavicle.
“This mark locks me to this vessel and essentially has me locked to whatever job I take. I can’t leave until it’s satisfied. Or else.” She drew her finger across her throat to mimic a knife.
“Test it if you want.” She said, zipping up her jacket.
“Okay, uh, get me a piece of cherry pie.” Dean said. She snapped her fingers and disappeared. Soon after she reappeared soon after with a plate of steamy cherry pie and a fork. She held it out to him and watched him grin and take it.
“I’m satisfied.” He smirked, starting to dig into it.
“Could you get the heart of a werewolf?” Sam asked, crossing his arms over his chest.
She smirked, “A challenge. I like it, Moose.” She snapped her fingers and disappeared. They stood for a few minutes. Crowley looked at his watch and smiled.
She reappeared finally. Her jacket was torn and her hair was disheveled. There was blood coming from her lip. She grinned, holding up a brown paper bag. The bottom of it was soaking and dripping with blood.
“Sorry for the wait. It was not ethically harvested.” She tossed it. Sam panicked and caught it. There was a wet slap as it fell into his hands. Dean looked up from his almost empty plate.
“That sucks.” He laughed and kept eating.
“Well, boys, satisfied?” Crowley asked. (Y/N) smiled, blowing a piece of hair out of her face.
“Fine.” Sam said, “We’ll call if we need you.”
Crowley snapped his fingers, the two disappeared.
Dean was scrapping cherry filling off the plate with the side of his fork. Sam stared at him, the noise of the metal against the plate echoed throughout the empty building. Dean put the fork in his mouth, looking up at Sam. He pulled the fork out of his mouth and shrugged, “What?”
The next few weeks were essential. Gaining the Winchester’s trust wasn’t easy. She went on errands and even helped kill a demon or two. Crowley said whatever was necessary.
After a hunt one night, Dean and (Y/N) went to a bar to drink to a job well done on a shifter hunt.
“Cheers.” He grinned and lifted his glass.
She smiled and clinked her glass, “Cheers.” They both knocked back a shot. He cleared his throat, looking at the shot glass.
“So… What’s the story with the Mark?” She asked innocently.
“Crowley didn’t tell you?” He said, avoiding eye contact.
“He did, but I wanted to hear it from the that pretty mouth of yours.” She rolled the sleeves of her red flannel up to her elbows.
Dean hummed, “Well it’s more of a pain in the ass than I thought. It’s taking over my life. Some days… resisting it is harder than others. I don’t know when I’ll be able to stop myself.”
(Y/N) shrugged, “Maybe you should give in every once in a while. Ya know, when you really need it.” She motioned to the bartender.
“I was thinking the same thing.” He admitted, surprising her.
“If that’s what it takes, to give into the mark and kill Metatron. Then… Am I willing to take the consequences? Would I could back from it?” He looked at the new shot on the counter, “For Sam? I’d do anything to keep him safe.” He took the shot.
(Y/N) began having doubts. I’m the last few weeks they had gotten so close. It almost felt like they were… Something…
She hissed in pain, grasping at her chests. The Mark on her chest burned, signalling that she was straying from her path.
Dean leaned forward, grabbing her arm, “What is it? What’s wrong?”
She couldn’t tell him. He would never trust her again.
“I’m straying from my assignment…” She said, looking him in the eye.
“How?” He asked, his eyes narrowing.
“For wanting to drag your pretty ass in the back and showing you a thing or two.” She bit her lip. Dean smirked, none the wiser.
“I think that could be arranged.” They made their way towards the back, leaving through the back entrance. He pressed her up against the brick wall, leaning down and began leaving sloppy kisses over her neck. He gripped onto her sides, keeping her against the wall. She sighed, running her fingers through his hair and tugging. Her eyes had been shut, but they fluttered open. There was a group of men standing there.
“Dean.” She whispered, shoving him away slightly. Dean looked up, looking over the the men.
“Uh… Kinda busy here. You mind?” Dean asked, his hands still held her to the wall.
“Didn’t know Crowley’s pet was free game.” The one at the front said, “Pass her over here, friend.” His tone was threatening. The group began closing in. Dean glared And stepped in from of her protectively.
“I would take a step back if I were you.” Dean said. The demon scoffed and punched Dean in the face, shoving him away.
“Asshole!” She punched him, but was shocked when it did nothing. The head demon pushed her back into the wall. He grabbed at her arms, and smirked. Dean looked up at them. His hold body was shaking with rage. The Mark started burning on his arm.
“Dean!” He heard her shout. Dean felt his rage burst in his chest.
(Y/N) watched as Dean roared, bringing out the demon killing knife. He just tore through each demon like they were flies. When the last one fell, he looked at her. His breath was ragged as he came down off his high. He looked around then grabbed his arm, his face contorted in pain. When it passed and he looked up at her, his eyes were widening horror. He looked around, seeing the dead bodies on the ground. He looked so scared.
(Y/N) sat at the bar, nervous for the time ever in her afterlife. She had asked Crowley to meet.
“Alright, darling.” He said as he arrived and sat in the stool next to hers, “You’ll have to make this quick. I have to go to the hell grounds. The hell hounds have been escaping.”
“Release me.” She said quickly.
“Excuse me?” He asked, grabbing his drink off the counter.
“I can’t do this. When you had me do this before it didn’t matter what happened to them. Now it does.” She said, “Crowley, he blacks out and when he comes out from under the influence, he’s scared and guilty. He can’t handle it.”
Crowley narrowed his eyes at his most prized demon, “You actually have feelings for him, don’t you?” she didn’t meet his eyes. He sighed and stood, smoothing out his suit.
“Well, (Y/N). Know that this gives me no pleasure.” He snapped his fingers. The Mark on her chest started to burn again. She shouted in pain, sliding down to the floor. She ripped open her flannel and watched as the mark on her chest because to to turn the skin around it black, eating away at her skin. She screamed, curling up in a ball on the floor. The pain was intense and spread throughout her body. Wet streaks began making their way from her eyes, nose, mouth and ears. She tasted her own blood. Crowley had started to walk away.
“Wait!” She called out. She screamed again, feeling the black start to invade her heart.
“Crowley! I’ll do it!” She screamed. He stopped, snapping his fingers again. She gasped for breath, watching as the black faded back into the mark.
“Don’t forget your place.” Crowley didn’t even look at her as he walked out. The other demons in the bar stared at her, then looked away when she stood. She snapped her fingers, leaving the bar behind.
Later, Dean and Sam had finally caught wind of Metatron. Dean would use the power or the mark and the first blade to kill him. Sam and Dean would go in alone.
Just as they were leaving, (Y/N) grabbed Dean by the jacket.
“Look, I know there’s not time. But… Don’t lose yourself, Dean.” She ignored the burning in her chest.
“I’ll be careful.” Dean smiled weakly and leaned down, pressing his lips to her forehead as a sweet goodbye.
After Dean’s death, (Y/N) went out on the run. Hiding from demon trackers and hell hounds to avoid Crowley. She had found a way around her mark. If the mark was broken, she would be free. The only issue was she had to keep breaking it. Everyday slicing through the mark with a blade forged in hell fire. Unfortunately, her running came to a halt. They caught her off guard and brought her to a tiny motel room. She was tied to a chair, but no devil’s trap, nothing to keep her contained. Which only meant something worse was coming. The door opened to reveal Crowley.
“Well, don’t you look comfortable?” He asked. He stood in front of her, moving her shirt collar to the side to reveal the scared mark on her skin. She looked away, not wanting to meet the face of someone she used to spend her whole existence trying to please.
“That would explain why I couldn’t just snap you out of existence. Not after what you did to Dean.” Her head shot up.
“What are you talking about? You’re the one who-” she was about to finish but stopped. In walked the only human she had ever loved. Dean was alive. But… Something was wrong, very very wrong. He … He was like her. A demon.
“What did you do to him?!” She shouted.
“Me?” Crowley said Innocently, “I helped resurrect him. If you had told him to give into the mark… Why… He would still be alive and not a knight of hell.”
Dean looked down at her as if she were a stranger.
“Dean, I….” She started to say but her words left her when she saw the first blade in his hand.
“I thought what better way to kill two birds with one stone. With you gone, I can avoid anymore incidents. And Dean can get his revenge.
Dean grinned and looked at the first blade thoughtfully.
"Dean, please.” She begged, “You never wanted this.” Her heart rate soared as he got closer.
“Personally,” Dean said, finally meeting her eyes. He grinned, usually s face that made her heart leap, but now it just sunk. She watched as his eyes flickered black.
“I like the the disease.” He raised the blade and struck.
Take it how you will. I may or may not have a thing for the idea that when Dean becomes human again the pain of this will just KILL him, ya know.
I hope you liked it!
