A/N: Out with friends I got this inspiration. What if Santana and Quinn were big sisters and what if Rachel was the baby? How would everyone act with siblings? I threw in an OC because I thought she could bring some balance I guess to the family of drama queens and fiery tempers.

Summary: Daughters. Stressful, yet wonderful; but when their entire world comes crashing down, is everything going to be okay?

Disclaimer: I only own my OC's!

Shelby Corcoran groaned, 5:30 already. She thought. Above her head, she heard the girls get ready for their first day of school Rachel wasn't going to be up until at least seven, but her teenagers had to look perfect.

Santana Mariana Corcoran was starting her senior and captain of the cheerios, one plus side to being captain was she got to boss her sister Quinn around all she wanted, but Quinn was her second in command and pretty much did everything together. She curled the ends of her hair and pulled them into a perfect pony tail.

Quinn Anna-Beth Corcoran had just finished her hair when she heard sobs coming from the room next to hers. Uh oh. Katie's crying. She thought. In her tank top and shorts that she slept in she went to see what was going on with Kaitlin.

In the middle of her little sister's hard wood floor, Kaitlin sat in a ball crying. The fourteen year old had anxieties about starting high school, especially since she had been chased from two other schools because of bullying. Kaitlin looked up when she heard someone walk in.

"Go away Quinn," the teenager said quietly. She was fat, and she knew it. She wasn't a size two like her sisters or mother she was in size 22 or 24 pants, and as much as she tried to not let it get her, she did and that's when the breakdowns happen. Shelby heard the crying down stairs and sighed sadly.

"Katie, it's a new year. You're going to be fine and think about this, you'll be at school with San and I. So come on, get up and I'll help you pick out an outfit, okay?" Quinn said walking over to her sister, Kaitlin's cheeks were tear stained and she noticed the girl's dark circles.

"You had the dream again, didn't you?" Santana asked standing in the doorway. It had been recurring since Kaitlin was five and it was hard for them to get through with it. Kaitlin looked up at her older sister's voice and Santana walked over, wrapping Kaitlin in a hug thanking her silently for still being in her pajamas.

Quinn walked over to the closet and grabbed a pair of skinny jeans, a loose fitting white shirt with clear patches and a blue tank top. She decided that Kaitlin should wear her knee high black boots with the fur on the top and also packed another pair of jeans and a just as cute shirt in her bag just in case Karofsky or someone slushied her.

"There boo boo, Quinn picked out an outfit. Now get ready and I will straighten your hair for you okay?" Santana said seeing Kaitlin smile at the use of her childhood nickname. Kaitlin was always called boo boo because that was all she would ever say. Boo boo. And it stuck. Shelby walked up stairs and saw the three girls huddled on the floor.

"Kaitlin, you okay?" their mother asked, she nodded tiredly and got up to grab her clothes, when she disappeared behind the bathroom door, Shelby looked at her two eldest girls.

"The dream?" Shelby questioned quietly. Before Santana could open her mouth Quinn answered.

"She's scared, Mom. Those kids tortured her to no end; and I tried to make sure she realized, she would be fine, but she isn't so sure. I packed an extra set of clothes just in case she needs them. Mom I'm worried about her, she's never had it this bad until the realization hit high school is here." Quinn replied quickly.

"I promised her we'd look out for her, but last night I got up to go use the restroom, and I heard her whimpering. They can't hurt her can they?" Santana asked. Shelby didn't have an answer. She thought Rachel would need the most attention which was true most of the time, but Kaitlin had a tough school year the year prior.

It was nothing new to Corcoran kids, a single mother with four girls, but Kaitlin almost lost it when she would walk down the hallways. For a while, everyone was scared to wake up in the morning in fear she would be gone or even worse, dead.

Kaitlin Rose Corcoran did her best to power getting caught up every once in a while; she was scared, everyone knew that. Was she going to be chased away again? Would she go back into her hole again and never come out?

Shelby kissed both of the girls and waited for Kaitlin to come out, Santana and Quinn went to put their uniforms on so they could help Kaitlin when she was done.

After fifteen minutes, Kaitlin finally emerged with fresh tears falling from her eyes. Shelby grabbed the brunette and held her close.

"Kaitlin, it'll be okay baby girl, I promise. I told the principal and the teachers if you need me at any time you were allowed to call, and Santana and Quinn are there." Shelby whispered quietly into her daughter's hair, Kaitlin sobbed louder. Then Quinn and Santana walked in noticing Kaitlin and just stood there watching their mother.

"Katie, c'mon. Will go finish your hair and you can wear my favorite perfume today, how about that?" Santana asked, Kaitlin reluctantly tore herself away from her mother and followed her sisters. Santana plugged in her straightener and sat her sister into her vanity seat; Quinn looked through her older sister's jewelry finding the earrings she was looking for.

They were imitation pearls, but they were perfect for Kaitlin. Santana ran the straightener over the younger girl's hair, gently and got the frizzy locks to smooth out perfectly straight. She took a clip, and pulled a section up a bit, making it half up half down.

By the time all three girls were done and ready for breakfast Rachel woke up, Kaitlin ran a comb through her sister's hair pulling it into a quick French braid before the young girl could get ready. Rachel pulled a short sleeved white shirt, pink jumped, white tights and black Mary Jane's. Her ears were decorated with gold stars and she was wearing a necklace her mother bought her.

All four of them went down the stairs to find their mom standing in the kitchen in a black pencil skirt and pumps, purple buttoned down blouse and her hair in loose waves.

Santana and Quinn grabbed an apple, Rachel her vegan cereal and almond milk, and Kaitlin downed a glass of orange juice and a bagel.

"So girls are we excited for our first day of school?" Shelby asked as she finished packing lunches. Rachel's contained mostly veggies and some fruit also a small vegan cupcake that the nine year old had talked Kaitlin into making with her.

Kaitlin's had her usual, a small salad, peanut butter and jelly sandwich, mandarin oranges, and a Gatorade. Santana and Quinn just had salads.

"No Ma, I'm thoroughly scared." Kaitlin said quietly grabbing her iPhone off the charger, followed by Quinn and Santana. Shelby lifted her daughter's chin to look at her.

"Kaitlin, sweetheart, I promise this year will be better. Just look at it with an open mind or Mama Corcoran will come down and kick some butt." Kaitlin smiled slightly, and walked over to her back pack, she had all her note books and various school materials. By now its seven thirty and the girls have to go to school. Santana and Quinn kissed Shelby and Rachel goodbye before rushing out the door waiting for Kaitlin.

Kaitlin hugged her mom tightly and felt the older woman kiss the top of her head before she turned to Rachel.

"Okay munchkin, I'm going to miss you. Love you." Kaitlin said kissing the top of her baby sister's head and left. Shelby watched the Santana pull out of the drive way in her Range Rover, she turned to Rachel.

"Okay Rach, go grab your bag, mommy's got to go to work." Shelby said grabbing her phone and car keys, Rachel ran off to return not even ten seconds later with a pink back pack over her shoulder.

She smiled and they walked out to the other Range Rover; Rachel was quietly humming "Don't Rain on my Parade." As the endured the longer drive to her elementary school, it was a magnet that specialized in music. All four of the girls attended the school. When they arrived Rachel said goodbye to her mother and walked into the school by herself.

About another fifteen minutes Shelby would arrive at Carmel and have to whip everyone into shape.

Lunch time arrived at McKinley and that stressed out Kaitlin beyond belief. She didn't want to go in there, she had made a few friends through her sisters Brittany, Tina, Finn and Puck, but this was the period her sisters were supposed to pretend she didn't exist right? Wrong.

The two upperclassmen grabbed their little sister and dragged her over to the table they were at with all the Cheerios everyone thought that they were going to prank the freshman, but the Cheerios knew who the young girl was.

"So, baby Q how do you like McKinley?" Brittany asked, she always swore that Kaitlin looked more like Quinn and Rachel looked more like Santana. So Kaitlin was baby Q and Rachel baby S.

"It's been okay, haven't really made many friends," the girl replied quietly, nearing a whisper, Santana grabbed her hand and squeezed it for assurance.

"You're okay, lil K." another cheerleader said; Kaitlin smiled slightly and started working on her oranges.

After lunch she said good bye to the Cheerios and walked to her locker, where she was met with a girl with long blonde hair, brown eyes and stood a little bit shorter than her.

"Hi, I'm Riley." she said happily, extending her hand towards Kaitlin, which she took cautiously.

"I'm Kaitlin, can I help you?"

"Oh, nothing really, why were you talking to Santana and Quinn Corcoran?" Kaitlin smiled but before she could reply, Santana and Quinn walked up to her.

"Hey Katie, Valley girl," Santana said looking at her younger sister and the girl.

"San, what do ya need?" she said annoyed looking at her older sister.

"Don't need to go all Brooklyn on me sis, Ma said you need to look at your phone." With that Santana and Quinn walked away and Riley just stared at Kaitlin.

"YOU ARE A CORCORAN!" the girl exclaimed. Everyone in the hallway looked at Kaitlin who blushed and ran into Mr. Shue's classroom.

He went through the list and paused when he got to Kaitlin's name.

"Kaitlin Corcoran?" he asked. Kaitlin raised her hand, everyone looked at her, and that was when it hit her everyone knew she was Santana and Quinn's sister.

After eight period Kaitlin was anxious to get home, she had made a few friends, Riley, some girl named Aniya, and Sydney.

When it came to after school, Kaitlin walked outside to find her mother's car out in the parent pick up area and before she could go a guy grabbed her. Kaitlin looked at him confused and then she recognized his facial structure and his eyes. It was her best friend from when she was younger, she pulled him into a hug before screaming.

"CHRIS! What the hell are you doing in Lima?"

Chris laughed at her and smiled, she sure had missed his a thousand watt smile.

"My parents moved here after Amy got a teaching job."

"So she's Ms. Capp?" Kaitlin inquired with a laugh.

"Yes ma'am." Kaitlin heard a horn honk in the distance and rolled her eyes.

"Gotta go, Mom is getting antsy." She smiled and gave him her cell number to text or call on and got into her mother's Range Rover.

"Hey mom!" the girl greeted giving her mom a kiss on the cheek. Shelby was puzzled, Kaitlin was never one to show much affection, only to Rachel honestly.

"Who are you and what have you done with Kaitlin?" Shelby joked, Kaitlin smiled and pulled out her phone when "Defying Gravity" sang out of it. She replied happily to the text and looked at her mom.

"Chris's family moved to Lima. Amy's teaching at the high school." Shelby smiled at her daughter, she had a crush. Chris and Kaitlin were best friends. They pulled away from the school and headed towards Rachel's school.

"So is he still cute?"

"Mom!" she whined.

"What?"

"Can we please not talk about this?" Shelby put her hands up in defeat briefly before turning back to the road. Kaitlin rolled her eyes and continued texting Chris.

They arrived at that elementary school, Kaitlin saw Rachel and got out, she was met with the nine year old flying at her.

"Katie, why do people have to be so mean?" she asked.

"What happened Rach?" Kaitlin said looking down at her sister. Rachel looked up, brown eyes filling with tears.

"I heard this girl talking about how you would be better off dead and so would I, because apparently we're too perfect. Katie, why did she say that?" Kaitlin crouched on the ground and looked at her sister's brown eyes.

"Rach, who said that? And it's because she doesn't like that our family. Which is stupid, because we are the best of course." she wiped away a few of Rachel's tears and looked at her baby sister.

"Some girl." Rachel looked over in the direction of a familiar face. Kaitlin looked over and tensed, it was the girl who tortured her in middle school. The girls walked over, and Kaitlin placed Rachel behind her.

"Katie, I can't see her!" Rachel protested, Kaitlin shot her a glare, and watched as the girls stood in front of her.

"Alexandra," the teenager said coldly, her blue eyes turning darker. Alexandra pulled her younger sister behind her like Kaitlin had done with Rachel.

"Kaitlin," she shot back, equally cold.

"What brings you around here?"

"Sophia. You?"

"Rachel. It seems our sisters aren't that fond of each other." Alexandra nodded, not breaking eye contact.

Rachel peaked around her sister and saw Sophia doing the same thing. Alexandra smiled wickedly at the nine year old.

"Looks like, she thinks she can protect herself. She can't."

"Honey, we're from the Bronx. You don't scare us."

"Oh really, is that why you left?" Kaitlin clenched her jaw. Rachel saw Sophia who looked kind of scared at her sister and Kaitlin and Rachel smiled slightly.

"Nope. Left on my own. Went to a different middle school, with more of an arts program."

"Here I was thinking it was because everyone knew your mother was a lesbian and you are a bastard child. But dammit." Kaitlin glared at her before replying.

"I had a father, don't you dare bring him up." Sophia and Rachel stepped out from behind their sisters.

"Get your tone deaf sister and leave!"

"Really? Calling my sister tone deaf? You and your sister can't even sing! And the only reason you get what you want is because you are a manipulative bitch."

Kaitlin made a mental note to talk to Rachel later, but was quite proud of the younger girl's word choice.

"Are you going to let Rachel talk to my sister like that?" Kaitlin was snapped out of her thoughts a took a step towards Alexandra.

"I don't care how my sister talks to your sister. She's going to turn out just like you. A money seeking whore, who only feels goods about herself when she's picking on somebody."

"Well, let's see about that when Sophia is a Broadway star." Kaitlin felt Rachel tense up. Kaitlin took a step towards Alexandra again, them about their nine year old sisters apart.

"Shut. Up. My sister can sing and is going to be on Broadway. Wanna know why? Because you and your sister can't sing. Why did I always get solos? I have the voice for it. So back off. Go. Get to steppin'."

Alexandra just smiled and went to walk away when she saw her mom walking towards, she stopped suddenly.

Kaitlin froze when she heard the familiar sound of high heels. Rachel looked back and saw her mother, before she went wide eyed, and turned into her older sister.

"Oh, shit." Kaitlin muttered. Shelby walked up beside her daughters and watched Alexandra and Sophia's mother do the same.

Erica, Alexandra and Sophia's mother, was short, long brown hair, brown eyes and she looked at the four time national show choir champion up and down. It was two generations of Corcoran's and Gomez's feuds. Every one had a reputation to uphold. In the end, Shelby had won, she had gotten the guy, the job, the perfect family. Or what Erica thought.

"Shelby," Erica greeted first, coldly. Shelby grabbed both of the girls and pulled them to her sides.

"Erica," Shelby replied back, she watched as Erica inspected the girls, before she smirked at the sight of Kaitlin. She felt Kaitlin tense again.

"Looks like my daughter was right, you really do let your kids eat fast food. If James was still around do you think he would still be with you if your child looked like?" She pointed at Kaitlin up and down and Kaitlin clenched her jaw.

Shelby glared.

"They are my kids. Leave them alone. If you have something against me, great. I don't care. But leave them out of it."

Erica laughed evilly, and Alexandra and Sophia glared at them.

"Has Shelby Corcoran gone soft? Wow." Shelby watched Kaitlin's eyes get darker blue then prior.

Kaitlin stepped in front of her mother and sister.

"That's it, you stuck up, snobby ass bitch. Shut the fuck up. Quit having some grudge against my mom. Just leave us the hell alone, get your daughters out of here and leave. Now." Kaitlin's eyes didn't leave the shorter woman's. Erica went to say something but Shelby stopped her by grabbing Kaitlin and pulling the blue eyed girl to her side.

Erica and her girls walked away and after they got far enough down, Shelby started laughing.

"Wow. Kaitlin. I don't condone swearing, but you got Erica Gomez to shut up. I never thought I'd see the day." Kaitlin smiled and helped Rachel into the car and noticed Erica screaming at her daughters. She got into the front seat next to her mother.

Shelby pulled away and heard Rachel singing to herself in the backseat. Kaitlin turned up the radio when a song by her favorite artist came on.

"My cousin's gettin' married at the Methodist church
That's why I stayed home from work
I'm supposed to hold the flowers
When the new bride kisses the groom
That's what I'm supposed to do
So what are we doin' with the windows rolled down
Twenty five passionate miles from town
Oh I love her like a sister baby but to tell you the truth
I'd rather ride around with you
The guy she's gonna marry's got money to burn
His daddy's a partner in some big law firm
Yeah that's how they're goin'
To Hawaii on their honeymoon
First class to Honolulu
She's never even set foot on a jet
I'm a little bit jealous I confess
I'd like to fly to Hawaii
But honey if I had to choose
Oh I'd rather ride around with you
I don't care where this road goes
No I don't wanna turn around
Let go of the wheel feel the wind blow
Don't even think about slowin' down
They're tyin' tin cans to the back of the car
Wonderin' where in the world we are
The preacher's done prayin'
And the couple's sayin' I do
That could be me and you
There's way too many decisions to make
The length of the dress
The layers on the cake
Oh one of these days I might get married too
But I'd rather ride around with you." Kaitlin sang happily, yes she idolized Reba McEntire among others and even saw her in "Annie Get Your Gun" in New York.

Rachel laughed at her sister's performance when they arrived home, Shelby said goodbye and went back to Carmel for the first Glee club meeting of the year for VA for freshman.

"Katie," Rachel said coming upstairs to her sister's bedroom, where she found Kaitlin passed out on her bed, apparently she had a rough day, more than she was letting on. Rachel walked over and saw her sister's cheeks stained with tears. She climbed up and curled into her sister's sleeping form, soon falling asleep herself.

Ever since Rachel was a baby, she always was drawn to Kaitlin, they were best friends but five years apart. Quinn and Santana were the same way. But all four of them were sisters, and acted like it, fighting, making up, and just being with each other.

When Shelby got home, it was oddly quiet. Usually Rachel and Kaitlin were watching TV or something, but then Santana and Quinn pulled into the drive way and noticed the same thing.

"Ma, where's boo boo and diva?" Santana inquired flipping over onto the couch landing on the remote and the six o'clock news was blaring on the TV.

"First, Santana Mariana Corcoran, do not do that on my couch, I would like to keep it. Second, I don't know, and third turn the damn TV down." Santana nodded and complied while Shelby and Quinn went upstairs, they heard familiar snoring and looked into Kaitlin's room. They saw Rachel sprawled across her older sister, clutching her teddy bear named Horace. After Horace Vandergilder in Hello Dolly. Which was Kaitlin's favorite musical.

Quinn climbed in next to Rachel, and felt the girl spread out a little more, and then she saw Santana who took the strip of bed next to Kaitlin.

"Really? No room for mom?" Shelby joked quietly, Santana shot her mom a death glare when she saw Kaitlin stir, sure it was inappropriate, but Kaitlin hadn't gotten much sleep the night before. She slowly walked out of the room and went to start on dinner.

Once dinner was finished, she walked back upstairs, and saw now all four of the girls asleep, something they were extremely good at, falling asleep. She woke Quinn and Santana gently, and then it was the task of Rachel and Kaitlin.

The three of them carefully pulled the nine year old from her sister, who awoke with not an issue. But it was Kaitlin that presented the most trouble, after slapping Santana a couple of times, she finally got up and went down stairs. Rachel took her Vegan lasagna and the others had three cheese lasagna. After dinner they cleaned up and went to get ready for bed.

Kaitlin climbed into bed listening to Brantley Gilbert, and soon fell asleep. Shelby had kissed all three of the girls, before she got to Kaitlin's room, where she saw the brunette tucked into her bed soundly. She saw Kaitlin's face turn into a weird expression while she was dreaming.

"Oh, baby girl, what is going on in that pretty head of yours? You were never good at hiding your feelings in your sleep." Shelby whispered kissing the girl's forehead. She left the room and went to sleep herself, but at two a.m. all of the girls got a rude awakening.

"NO! DON'T HURT HER!...PLEASE!" Kaitlin screamed out in her sleep, Shelby ran upstairs and found the teenager covered in sweat. The dream came back. It was a dream that had haunted the young girl from when she was five.

Santana and Quinn rushed in a gently coaxed the girl awake, whose body was now shaking with sobs.

"It-it was d-dif-ferent this ti-time. It wasn't just da-daddy, it was ev-every-everyone." Kaitlin managed out. Everyone turned when they heard someone by behind them, a sleepy Rachel walked over to her older sister curled up next to her.

"So since everyone has school tomorrow, let's just go down stairs and sleep in my bed. That means everyone." Shelby pinched the bridge of her nose and turn to go down stairs, Rachel and Quinn followed but Kaitlin and Santana stayed behind for a bit.

"Katie what happened?" her oldest sister asked her. Kaitlin tried to shake the memory, but it was too hard.

It all started when she was five, it was September in New York and her mom had the day off, so did their dad, everything was going as planned.

Kaitlin Rose Corcoran ran into her parents bedroom to find her mother laying in bed with her nine month old baby sister, and the news on. A horrible car accident in an intersection left two people dead and Kaitlin was curious as to where her dad was.

"Mommy, where is daddy?" Shelby sighed and looked down at her, she felt the tears come on again and motioned for the girl to come up on the bed, the five year old struggled to climb on top of the large bed, but when she did, she curled next to her mother and baby sister watching the news with her.

"Mommy, seriously, where is daddy?"

"Katie, please just wait until your sisters are up, okay?" Kaitlin nodded and curled into her mother watching Rachel play with her fist. Santana and Quinn soon came in after that, and sat on their parents bed looking at their mother curiously.

Her eight year old, seven year old, and five year old all sat crossed legged and waited to hear what their mother had to say.

"Girls, daddy was on his way to go get coffee and breakfast for us, when his town car was hit by a delivery truck." she stated sadly. "And, I'm afraid daddy didn't make it." Shelby looked at her girls, and Kaitlin looked at her confused while Santana broke down into tears as well as Quinn.

"Mommy, what do you mean?"

"It's means daddy is dead Katie!" Santana snapped, Kaitlin looked horrified at her older sister and ran away crying. She hadn't intended to be so mean to her little sister, but it just came out. Shelby picked up Rachel and had her two oldest girls follow her, Kaitlin was sat in her dad's favorite chair crying.

From that moment Kaitlin Rose Corcoran changed, memories of her father faded to grey, and she had a nightmare for a long time, about her dad's car accident. And if the man who had killed her father had come after her.

Kaitlin shook her head, not wanting to talk about it. It was always the same, one time she was playing in her room, and then he comes after her, beating her and killing her, and she always woke up before her mother could scream about finding her murdered.

It always came when she was nervous or had a bad time, and by now, Santana and Quinn were used to hearing Kaitlin scream in her sleep, Rachel however wasn't.

Santana grabbed her younger sister's hand and led them down the stairs, to find their mother, Rachel, and Quinn quietly talking, Kaitlin curled up next her mother, Rachel curled up next to her and Quinn took her mother's left and Santana beside her.

Shelby smiled when she heard the girls soft snores, she sighed deeply and fell asleep soon herself.

For now, they were okay, Kaitlin was alive, and nothing in the world could bring them down, or could it?

A/N: What do y'all think? I've been working on this forever it seems like, anyhoo, review story alert, etc! Thanks guys!
