Sextuplets x Sister! Reader

Hahaha... I'll be honest with ya'll... I've been thinking of this one for a while.

Nothin' inappropriate if that's what you're thinking. Just fluff I guess. But you guys/gals shall be the judge of that. ^^ 

I do not own the song nor video. All rights go to Caleb Hyles and Rebecca Sugar

It's been years since you were adopted by the Matsuno family. You never had thought of being adopted in your time at the orphanage. You would always remember the day your mom picked you out of the other children.

flashback

-Your POV-

Time at the orphanage wasn't as bad as movies make it. Sure, some chores here and there. But not back breaking work. You sighed a bit. 'I wonder if I'll ever get a real home', you thought. You were sitting on your bed in your shared room. Sighing again in boredom. 

"(Y/N)! Come down here please!" Yelled Betty, whom was the head of the orphanage. She was very nice to you and was your only friend. You weren't very social. Even at the age of 9 you weren't very social. "Coming!", you yelled back. You left your room and walked downstairs. You see Betty and a woman with a woman with glasses and had her brown hair tied in a bun. She was wearing a long sleeved shirt and a tan skirt. She looked your way and smiled warmly. You blushed and hid behind Betty. "Hello there dear. I'm going to be your new mother." You looked at her surprised. Then looked at Betty. She smiled down at you. You teared up a bit and smiled brightly. You hugged the woman. Then pulled back quickly blushing madly. "S-sorry..", you said quietly. The woman chucked. "Go get your things ready (Y/N). While Mrs. Matsuno and I finish signing some papers." Betty said. I went back to my room excitedly. You would be lying if you said that you didn't run to your room. You gathered all your things that you had and walked back downstairs. You waited til they were done. Betty looked down at you with a sad smile. "Well I'm going to miss you (nickname)", she said hugging you. You teared up and hugged her back. She broke the hug wiping her eye. You turned to, you guessed, Mrs. Matsuno. You smiled at her. You grabbed her and and looked back at Betty. When the both of were walking out the door; you waved back at Betty smiling brightly.

When the both of you got home Mrs. Matsuno introduced you into her husband. He smiled kindly at you. Then you heard loud footsteps from the stairway. You started to panic a bit. The footsteps stopped. You looked up to see six boys with same faces. Your eyes widen a bit, so did theirs. You guessed from their age they're a year older than you. Mrs. Matsuno looked over to them. "Ah, boys I'm glad your here!" she said with a smile. They all looked at her confused. "I would like you to meet your new sister." Mrs. Matsuno introduced you. Well..kinda.. "Go on dear. Don't be shy. Introduce yourself to your new brothers.", she smiled. You were shaking a bit cause they were starring at you now, waiting for an answer. 'S-she never said anything about having brothers..! Let alone 6!', you thought. "A-ah.. M-my name is (Y/N). Please t-to meet you..", you mentally cursed yourself for studdering. You hear them all say 'kawaii'. Though, they probably thought you didn't hear them. One of them stepped out a bit. "I'm Osomatsu! The eldest of the sextuplets.", he said excitedly. "I'm Karamatsu! The second eldest." Then the other boy did the same. "I'm Choromatsu, third eldest!" He seemed to be a bit shy. "I'm Icimatsu" the boy said kind of emotionless. "I'm Jyushimatsu! Second youngest!" You looked at him and smiled a bit. "And I'm Todomatsu. I'm the youngest one of the sextuplets." The last boy said. You looked at all of them. Feeling a bit less shy now. "N-nice to meet you all.", you said with a bow. Your mother then told your new brothers to show you to their shared room. And from there on all of you got along very well.

flashback ends

 You chuckled quietly. All seven of you turned out to be NEETS. You didn't seem to mind that much though. Spending time with your brothers always made you happy. You sat up on the futon. You couldn't sleep. You looked over to your sleeping brothers. You quietly giggled seeing Jyushimatsu laying across on Osomatsu and Todomatsu. Sighing a bit, you got up and quietly opening the closet door. Taking out noise canceling headphones. You put them on your brothers and parents. You always did that when you wanted to play your piano late at night. Little did you know; the sextuplets weren't actually sleeping.. Well.. Jyushimatsu was, the other weren't. They knew you tend to play your keyboard when you can't sleep. You walked downstairs with your keyboard. The Matsuno brothers quietly following you. You set your piano on the table and turned it on. You started to play. To the brothers surprise you started singing.

  "If I could begin to be
Half of what you think of me
I could do about anything
I could even learn how to love

When I see the way you act
Wondering when I'm coming back
I could do about anything
I could even learn how to love like you
Like you
Love like you"

You sang, continuing to play. You felt like people were watching you, but didn't pay attention to it.

  "I always thought I might be bad
Now I'm sure that it's true
'Cause I think you're so good
And I'm nothing like you

Look at you go
I just adore you
I wish that I knew
What makes you think I'm so special

If I could begin to do
Something that does right by you
I would do about anything
I would even learn how to love"

"I didn't know she was a good singer", whispered Osomatsu. The other nodded their heads, smiling at the sight they have. Ahem. No not that kind of sight. 

"When I see the way you look
Shaken by how long it took
I could do about anything
I could even learn how to love like you

Love like you
Love me like you"

You finished singing, but continued to play a bit longer. After you finished the song, you heared clapping behind you. You panicked and turned around only to see your brothers clapping with exaggerated tears in their eyes. You, on the other hand, were blushing so much it looked like your head was going to pop. "That was so beautiful little sister!", said Osomatsu. "I agree my number one Karamatsu girl! That was more beautiful than every sunset!", said Karamatsu painfully... Very painfully. The others only nodded. Then Totty spoke up; "I'm so glad I caught that all on video!", he said looking down at his phone. That caught your attention. You smiled at him. "Todomatsu onii-chan", you said very sweet like. The others flinched. They all know that voice too well. "Y-yes (Y/N)..?", Todomatsu asked nervously. "I'll give you three seconds to run." You chucked darkly. 

"(Y/N).. Dear sister-" 

"One"

"N-now now.. You wouldn't hurt someone as cute as me!"

"Two"

"Um.. Totty I would start running if I were you.."

"THREE"

Todomatsu screeched and started running. You started chasing after him, trying to grab him. The others standing in the same spot laughing a bit.
