Supernatural Imagines

Imagine being sam and deans older sister

I'll probably do a second part to this, because I feel there's more to do with it, and I really enjoyed writing it! Thank you to @shae-101 for the request!
"It's a wonder why no one has thought to use you prior, what with your brothers obsession with family, and all." The demon, choosing to use the guise of your father. It wasn't an unusual choice, but it never really got to you either. Honestly, might as well be 'as on earth, as in hell'.
"We kept your body." The black haired man, now about what your age would be, had you lived longer, pointed behind him as two other
demons dragged a meat suit through your cell door.
"We even aged it so you'll still be big-sister y/n. You're welcome." His snarky tone made you want to punch him.
"Oh, why thank you for the kind consideration." Venom leaking in your sarcastic comment. The demon, (if you remembered right) Kythlo, threw his head back in laughter, the sound resonating in your father's tone, making you physically gag. With the black-eyed bitch smirking wildly being your last sight, you were blinded with both searing white pain and sight...

You woke up in a plain room, on some sort of concrete flooring. You looked down at your hands, bending your fingers only slightly before you heard small pops in the joints.
"I-I'm alive?" You were genuinely shocked. You expected it to be some kind of sick trick or to wake up with the current king or queen of hell torturing you for information. Standing up fully, you began wandering the large metal and concrete structure.
"What is this? Some kind of... bunker?" One thing was for sure; You. Were. STARVING! Exploring a bit deeper into the mainly concrete structure, you eventually found a small kitchen, one that, luckily, seemed fully stocked. Whoever owned this place was definitely awesome, because you opened the fridge to find four separate pies. Pulling out the (favorite pie type), you took two slices before returning it to its place in the fridge. Nostalgia flooded over you, its waves pluming out from your mind, vast the barrier you'd put up to protect yourself in hell. You remembered Sammy being in your lap as Dean, dad, and yourself ate pie at an old-style 50s diner. The little toddler cooed, in a plead for a bite. You had scooped up some of dad's rhubarb off his plate, giving the bite to the small child. His face had instantly scrunched up from the sour flavour you were unaware of, and he spit it out on Dean's napkin.
"Huh. Guess he isn't a fan of pie?" Dean had asked unsurely, and you and dad smiled as you laughed at the seven year old. It made you wonder how they turned out. Dean had always been a big pie fan, eager to be just like his big sister and father. He'd where dad's military jackets, and your band tee shirts and flannels. Holy crap, if Dean didn't still love Kansas, you'd knock his lights out. Finishing up the pie, you made your way back to the kitchen, cleaning the dishes in the sink, rather than just dumping them. It wasn't long until you heard the heavy bunker door being forced open, and two voices came crashing into the previous stale silence with what sounded like an argument.
"No way, dude! Kansas. All night long, got it?" A gruff man's voice echoed throughout the concrete area. Someone groaned.
"Come on, Dean. Spare me the torture and just eat some pie, alright?" A slightly higher in pitch, but still obviously belonging to a male, answered.
"Dean?" You breathed silently out, a smile creeping to your face. Realizing the footsteps were nearing your little 'hiding' area, you snuck around the bend, and through the other door. Keeping your ears open, you cautiously listened in as Dean removed the pie you had been eating from the fridge, while Sam put on a pot of coffee.
"The hell?" His brows scrunched together, his confused tone attracting Sam's attention. Sam continued to brew the coffee, not thinking much of Dean's abrupt and odd comment.
"What?" Sam was obviously distracted, likely with pouring his coffee.
"The pie! Did you eat it?" Yep, definitely the same old Dean.
"What? No, Dean!" There was a sound, like a birds' wings flapping, but on a much louder scale.
"Who are you?" A monotone, gruff voice inquired from behind you. Jumping as you turned around, and falling back into the kitchen, landing on your back, and rolling over and back onto your feet, ready to fight, need be. Your brothers were also ready, as well as this magic-man. Dean held what looked to be a basic steak knife... Amateur. Dean knew better than to work with a demon, surely, so what exactly was this guy?
"Y/n. Now, better question, what are you?" The knife slipped like brother from Dean's hand, clattering to the ground, shocking the other three of you. The moment you turned to him, his arms were tied tightly around you, him using his hand to bury you into the flannel fabric he was wearing over his grey cotton tee. Smiling softly, you wrapped your arms equally as tight around his waist.
"Yeah, yeah, I missed you, too." Suddenly pulling away from you, in an epiphany, but also excitement, he spun you around towards the weird, trench-coated man with the mega-awesome azure eyes.
"Sis, this is my boyfriend, Castiel. He is an angel, since you were wanting to know." Your smile must've become visibly brighter, because in a moment you felt all the pride in the world. Dean had done gotten a boyfriend, and from his tone, he was truly in love. You wanted to rush up to the man, erm- angel- and hug him, thank him. Thank him for the blessed gift he'd given your baby brother. Holy hell, this was amazing, beautiful, not to mention perfect!
"You must be y/n Winchester, Dean's older sister." His tone was still pretty much nonexistent, but he forced a small smile as he offered you his hand. Sam was dumbfounded.
"Woah, woah, wait- What do you mean sister?" It figures Sammy wouldn't remember you. He had been so young when it happened, after all. Turning to the confused giant you still remembered as a tiny little boy, you took in everything he had become.
"Sammy," You breathed out, stifling tears, "I- Oh! Look at you!" You brought your hands to your mouth to hide a smile. Dean placed his hands on your shoulders, and only said one thing;
"He's dating an angel, too. An archangel, named Gabriel." Sam blushed profusely as everyone else laughed. A similar sound as the one you'd heard when Castiel arrived, and suddenly there was a man about your height hugging Sam from behind.
"It's okay, Samsquatch!" He joked, placing his lips to Sam's shoulder. How had a lifetime go by so fast? Who cared? You had them back, and anyone who dared to think different could go straight to hell, and not collect $200.
