Changes Part 1 |Sam and Dean x Sister!Reader |

He saw a tall figure, though still shorter than himself, walking around. He saw him headed in the direction Sam was and the Winchester slunk back in the shadows, quiet as a mouse. He waited until he heard the footsteps get closer, his heart beating in anticipation.

Who the hell was here in his apartment, and what the hell was he trying to do? Sam found he didn't care too much. That wasn't first priority.

He held his breath until the man walked into the same room as Sam, and then he lunged. His arm was quickly knocked away as he grabbed one of the broad shoulders and he suddenly ducked as the man's fist aimed to connect with Sam's body.

Though before the taller of the two could retaliate, his arm was grabbed and he was turned around and pushed backwards. A kick was blocked and then Sam was once again shoved, this time into the next room.

Sam bit his tongue once the man's elbow connected with his face, and again his kick was dodged. The shorter one swung his fist again, and while Sam blocked it, he was still knocked down and then pinned, the man's hand on his throat and the other one his wrist.

"Woah, easy tiger."

Sam inhaled deeply, trying to catch his breath as he looked up at the man. He lifted his head up lightly, confusion etched all over his face.

"Dean?"

The man laughed, confirming his identity. Sam rolled his eyes at his older brother.

"You scared the shit outta me!"

Dean shrugged, "That's 'cause you're out of practice. You wouldn't be, if-"

And before his sentence was finished, they were flipped over. Dean's eyes were amused, though slightly irked his brother had managed to overpower him, but not too much.

"I guess I stand corrected, don't I?" He said flatly, "Now get the hell off me."

Sam shook his head and stood, pulling his older brother off of his apartment floor. He looked into the green eyes of his sibling, not quite sure what to make of his presence.

"What're you doing here?"

"Thinkin' about havin' a beer, thought about you." He gave him a fake smile.

Sam wasn't amused, "What the hell are you doing here, Dean?"

The older one sighed, "Alright. We gotta talk."

"They have phones for that." Sam said dryly.

"Would you have answered?" Dean shot back.

Suddenly the light was turned on and the men looked over to see Jessica, obviously tired and confused as to what the hell was going on so late at night.

"Sam?"

Sam sighed, "Dean, this is Jessica, my girlfriend."

Dean smiled appreciatively, his eyebrows shooting up for a moment, surprised a woman that good-looking was with his younger brother of all people.

"Dean, as in, your older brother?" Jess asked, a smile growing on her young face.

Sam nodded and Dean grinned, looking at her shirt. "I love the Smurfs… Anyway, you are way out of my brother's league, you know?"

"I should go put something on…" Jessica said awkwardly, turning to leave.

"Na, don't do that. I wouldn't dream of it. Seriously." Dean moved back to his brother, eyes on Jess the entire time.

Sam glared at his older brother, obviously already way past annoyed.

"Sorry honey, gotta borrow your boyfriend here. Family business talk."

"No." Sam said, face stony. There was no way this was happening.

He moved to his girlfriend, snaking his arm around her waist, "You got something to say, you can say it to both of us."

"Fine. Dad hasn't been home in a few days." He said, any traces of amusement long gone.

"So? He's working overtime. He'll be back sooner or later."

Dean clenched his jaw, "He's on a hunting trip, and he hasn't been home in a few days."

And while his expression never changed, his demeanor on the inside sure as hell did. He looked down at his girlfriend.

"Excuse us. We have to talk outside."

Jess nodded and Sam went to put on a hoodie and pair of jeans, taking his girlfriend with him into the bedroom to prevent Dean from flirting with her any more. He was silent as dressed, saying nothing until he and Dean were outside, the older Winchester providing an explanation as to why he sought his younger sibling out.

"You can't just break into my apartment and expect me to up and leave with you, Dean." Sam responded, annoyed.

"Sammy, you're not listening. Dad's missing, and I need your help to find him."

"Then what about (Name)? She can help you just fine."

Dean sucked in a deep breath, "Not gonna be enough. I need you too."

"Why? She's more experienced than I am by now."

Dean breathed in sharply, "Sammy..."

"Speaking of (Name), where is she?" Sam noticed something was off when he didn't see you with Dean. You'd practically been glued to him your entire life.

Though that wasn't to say you didn't love Sam just as much. He knew you loved him, and he loved you too. But your bond with Dean had always been stronger. Hell, you were closer to Dean than your own father and vice versa. Sam supposed it was the biggest brother, little sister aspect of it.

"In the car. Look, are you coming or not?"

"No. I swore off hunting for good."

"It wasn't so bad…" Dean muttered, "Not easy, but not that bad."

"Yeah? I told Dad I was scared of something in my closet, he gave me a .45."

Dean stopped walking and looked at his younger brother, "Well what the hell did you expect him to do? You know our line of work."

"I was nine!" Sam whisper-yelled, "I expected him to say not to be afraid of the dark."

"Like I said, you know our line of work. You damn well should be afraid of the dark."

"I know, but still. You think Mom wanted this for us? Wanted (Name) to do this?"

Dean said nothing and rolled his eyes, continuing his way to his prized Impala. Sam inwardly groaned at his brother's attitude about it.

"Dean, we were raised like warriors. And you know what? We still haven't found what killed mom."

Dean ignored his brother's last statement and looked into his eyes, "So what're you saying? You wanna live some normal, white picket fence, wife, two and a half kids life?"

"Not normal." Sam said, staring right back at the older Winchester, "Safe."

Dean said nothing, but Sam knew exactly what he was thinking.

"I was going to college. That's what I wanted, and Dad's the one who said to stay gone if I was gonna go, so that's what I did."

"Oh yeah?" Dean asked, unimpressed, "Well listen to this. Dad's in trouble, and if he's not dead yet, he will be. Look, Sam, we can't do this on our own. We need you. And if you're not gonna do it for Dad, do it for me. And if you're not gonna do it for me, do it for your baby sister." He said seriously, venom edging his words. He pointed to the car, where Sam saw a glimpse of you sleeping in the passenger seat, your pale skin glowing against the light of the streetlight.

Sam took a deep breath, "What was he hunting?"

Dean grinned and moved to the trunk, opening up the arsenal, looking for something.

"Why didn't either of you go with Dad?"

"We were doin' our own job down in New Orleans." He commented absently, digging through.

"He let you two go on a hunt without him?"

Dean looked at his brother, "Dude, I'm twenty-six. I can take care of us."

The older Winchester caught the younger one up to speed on everything, showing him the documents he'd been looking for and playing the voicemail he'd received. Afterwards Dean closed everything up and looked at Sam.

"I haven't bothered you for two years, Sammy. Never asked you for a thing." He threw out his final pitch, knowing that coupled with the fact he'd let you down if he didn't come along would convince him.

Sam sighed and pinched his nose, "Fine. I'll help you."

xXx

Dean leaned on the side of the Impala, waiting for Sam. He opened the back door and let Sam toss his bag in before moving onto the driver's side, turning on the car. Sam slid inside behind Dean and looked diagonally to him.

"She's grown." He said softly.

Dean looked over at you, smiling proudly. "Yeah. She's beautiful, just like Mom."

"How was she, after I left?"

Dean gnawed on his bottom lip, trying to find words to carefully spell out what it was like. He eventually gave up with a sigh.

"Not what matters, Sammy. In a few hours we'll stop at a motel for the night."

Sam said nothing and the car was silent, save for Dean's music, which was uncharacteristically on a low volume. House rules said the music got to be as loud as the driver wanted no matter who was sleeping, and Dean loved his music loud. Sam didn't voice his questions out loud though, instead choosing to stare out of the window.

There were a few times where Sam could've sworn you whimpered, but the second Dean's warm hand touched you, be it by gently rubbing your thigh or grabbing you shoulder for a moment, you were silent again.

What the hell was that all about? Last he checked, you didn't have nightmares.

But it had been a long time, and since then you'd seen many new things. So maybe it was totally normal for an occasional nightmare. Hell, he had them and he'd sworn off hunting an entire two years ago…

Dean pulled into a motel parking lot and found an empty space, pulling in and stretching once he got out, letting out a tired groan as he did. He tucked the keys to the Impala in his pocket and moved to your side of the car, opening the door and crouching down. Normally this would be when Dean plugged your nose to wake you up, and while Sam knew it was a jerk move, he couldn't help but laugh at his older brother's shenanigans to their baby sister.

Needless to say, Sam was surprised when Dean undid your seatbelt and picked you up out of the car.

He looked at Dean and raised an eyebrow. Dean just shook his head. "She hasn't slept this long in a long time. I'm not messing that up."

Sam nodded and they walked inside. The person at the desk looked a bit concerned upon seeing Dean holding a sleeping woman, but said nothing during the transaction. She slipped them their room key and bid them a goodnight, to which the boys did the same, quietly.

"There's only two beds, and no couch." Sam said as they walked to their room, "And there are three of us."

"I figured. It's pretty late." Dean muttered as he carefully laid you down on one of the beds. "I'll bunk with (Name) tonight."

Sam looked at his brother, perplexed. Dean always hated sharing a bed, and would always pout if he had to sleep in the same bed as one his siblings.

"You sure? I know you don't like sharing."

"I'm sure." He mumbled, pulling off your shoes and socks and grabbing one of his shirts from his bag, "I'm not making either one of you sleep on this nasty ass carpet. I'm nice like that."

Sam shook his head and went into the bathroom to get changed, leaving you and Dean alone. He sat you up, shushing you lightly as you began to moan in frustration as you felt yourself being moved.

"It's okay, baby girl. I'm just trying to get you in some more comfortable stuff to sleep in."

You nodded lightly and held your arms up a bit, eyes still closed. He tugged up your shirt and set it to the side, sliding on one of his over your tank top. You pushed your jeans down your thighs and stopped at your calves, already halfway back to sleep. Dean chuckled lightly and pulled them down the rest of the way, tugging the shirt down over your panties and allowing you to lie down. He pulled the covers over your body and kissed your forehead, folding your clothes and shoving them in the duffel bag.

He quickly switched out his jeans for basketball shorts and shed his jacket and t-shirt. Just as Sam came out of the bathroom with plaid pajama pants and a light blue t-shirt, he slid on a black tank top.

They wished each other goodnight and climbed into their respective beds, the lights going off instantly after. Dean laid flat on his back as you curled up on your side, your back to him, and Sam fell asleep nearly instantly, spread eagle as usual.

xXx

Dean was the first awake that morning, which was unusual, to say the least. Usually it was Sam, then you, and then Dean. Regardless of the usual pattern, he sat up and changed into a fresh pair of jeans and a clean black t-shirt, his trademark leather jacket making its way back onto his body. He wrote a quick note and placed it on his pillow, tying on his shoes afterwards. He leaned down and kissed your forehead, pulling the covers back around you snugly.

He quietly left the motel and went to the gas station to get breakfast for the three of you. He could only hope that he'd be back before either one of you woke up…

About five minutes after Dean left was when Sam stirred, groaning as he lifted his head up to look at the bed on the left side of him.

No Dean, but you were still blissfully asleep.

Dean had said you'd been sleeping for an hour before he even got to Sam's apartment, and you were out cold the entire ride to the motel and even when Dean carried you.

How tired were you? He always remembered you being able to sleep like a baby. When you were little you were always first up, and on the days when Dean wouldn't wake up no matter what you did, you'd wake up Sam.

He sighed softly and sat up, running his fingers through his hair. He opened up his bag of clothes and moved to the bathroom for a quick shower. He was drying off his hair as you began to wake up, though you were unaware of his presence.

Sam noticed movement and smiled softly, sitting at the edge of the bed and running his fingers through your hair. You jumped and locked up, deathly silent.

Sam furrowed his eyebrows. He cupped your cheek (Was that a whimper he heard?) and turned your head to look at him.

"(Name)…" He said softly, "It's me."

You flinched and pulled away, fear in your eyes. Your lip trembled as you looked at your brother, tears in your eyes. Sam looked at you, completely perplexed.

"(Name)-"

The door burst open and you jumped again, pulling your knees up to your chest and winding your arms around them, hiding your face as you let out a small, terrified wail. Sam looked up and saw Dean, still confused and now upset.

Dean raised an eyebrow until he looked over and saw you curled up and shaking. He muttered a string of swears before shoving the bags of food into Sam's arms and rushing to your side, pulling you into his arms.

"It's okay, baby, nothin' bad is gonna happen to ya."

You relaxed in his arms and wound your own around him, holding him as tight as you could. Dean kissed your hair and rubbed your back. Sam bit his tongue before standing, putting together his bag and looking at his siblings.

"I'll be waiting at the car."

Dean reached into his jacket pocket and tossed the keys to his brother, saying nothing. Sam tossed one last glance at you two over his shoulder before going to the Impala, trying to understand just what the hell had happened.

You were terrified of him. It was like you had no idea who he was! And even if you were scared at first, you definitely wouldn't have locked up like you did! You'd have his ass pinned down in half a second! He watched as your father and Dean trained you to fight, and while they said it was for demons, Sam knew it was them also making sure you kicked any man's ass that touched you.

Something had changed. He had a feeling that it wasn't a very good one.

He heard foosteps just as he reached the black Impala. He turned to see Dean.

"So, I saw some cop cars headed to that bridge and I think we should-"

"Woah, woah, woah." Sam started, annoyed as he held his hands out, "You can't just act like there isn't a problem here."

Dean shrugged, "What? Dad's missing, we've got a job-"

"And our little sister is nothing like she was two years ago."

Dean swallowed thickly, his Adam's apple bobbing up and down. He rolled his shoulders back and sighed.

"Sam, we've gotta case to take care of."

"Yeah, I get that, but my baby sister looked like she didn't even know me!" Sam shouted.

"That's because she doesn't." Dean said, hands in his pockets, his green eyes staring hard at the ground.
