Osomatsu san x Sister!reader

(10) It was an accident....

You were eating some oden that Chibita gave you, you were just minding your own business. Thinking about your brothers and such, you're still really confused about your feelings towards them. Heck, you now already kissed ALL of them. Everytime you think about them kissing you makes you blush.

"(Y/N)!" A fimiliar voice called out to you, making you lose your train of thought. It was one of the brothers but you dont know which one.

"Eh? Ummm...yes?!" You respond to the voice by yelling.
"You dont have to yell, y'know. Im right here"  the voice was heard behind you, you turned around and it was a grinning Osomatsu!

"Osomatsu nii-san! You called for me?" You asked the grinning dork, he chuckles.
"Yeah, I want you to come with me." He gestured his index finger for you to go with him.

"....where...?" You lifted an eyebrow.
"A flower shop." He said, casually.
"Okaayyy???" You were still confused and got up from the floor and put on your (F/C) hoodie with the Matsuno symbol on it.

The nearest flower shop was a 4 minute walk from your house. But as the both of you were heading there, it was awkwardly quiet, no talking whatsoever.

"Errmmm...sooo why are you going to the flower shop?" You asked the eldest, breaking the silence.

"To buy flowers, duh." He smirked

"I know that, idiot. Im asking who is it for?" You got a little irritaded

"Totoko-chan" Osomatsu turns to you.
"I see, but why do you want ME to come?"

"You're a girl, and also Totoko-chans best friend. You can help me pick out a flower for her" Osomatsu placed both of the palms of his hands behind his head.

Once you two finally reached the flower shop, you started looking for Totoko-chan's favourite flower. Roses.

"Here's the roses Oso nii-san." You picked up a pot with a healthy rose on it.

"No, no. I want a bouqet of them." Osomatsu waves his hand slightly at you. You put down the pot with the rose.

That's when you spotted a (F/F)
(Favourite flower) near a shelf by a window. It got your attention and you really wanted that flower, you stared at it for awhile untill
"(Y/N), I bought the bouqet already, lets go!" Osomatsu called out to you, you quickly turn around and follow him outside the door.

You thought that you two were going to Totoko-chans place but Osomatsu is heading to...the Mall?

"Why are we going to the Mall?" You asked the man in red.
"Totoko-chan promised me to go shopping with her, might aswell you go too"

"Why arent the other five come too? Usually the SIX of you help her with shopping?"

"Shhh dont tell them! Hehehe" He rubs his index finger on the bottom of his nose. You rolled your eyes.
You finally reached the Mall where an angry fish girl was waiting at the entrance.

"Where were you?!" She shouted at Osomatsu
"I went to the flower shop and bought you this" He blushes slightly as he gives Totoko the bouqet.
"Thanks, I guess....oh, Hi (Y/N)!" Totoko waves at you, you gave her a soft smile.
"Where are the other NEETs?" She asked the both of you.
"They ate really spicy oden yesterday and now have exsplosive diarreah." Osomatsu said, bluntly. You gave him an
Are-you-sure-about-that  kind of look.

After that, the three of you went inside the Mall and Totoko-chan did most of the shopping for herself while you just accompanied her and leaving Osomatsu to carry all the bags.

"Hey, Totoko-chan, dont you think we should help Osomatsu nii-san with the bags..?" You asks her as she payed her new fish outfit.

"Naaah, Im sure he's fine! Besides, we're girls, the men are always the one to help the girls, right?" Totoko-chan smiled.

"Well, yeah but you buy so many stuff!" You complained to her. She ignored you saying that.

"Are you sure you dont want to buy anything? I'll pay for you" She asks you one last time before leaving the store.

"N-no, thanks" You declined, mostly because you dont want your brother carrying more stuff than what he already had. You two went out of the store to find Osomatsu waiting for you, carrying 8 heavy bags, 4 bags on each hand.
"Huff...huff....are we...huff..done?"
He said, trying not to sound tired.

"Yep! Here's another bag!" Totoko hands over one last bag to Osomatsu but since the other bags were weighing his hands down, he was unable to grab it.
"Here, let me just carry it" You chimed in and carry the last bag for Osomatsu. You felt a little bad so you decided to help him a little bit.

The three of you finally reached to Totoko-chans house, she turns to you.
"Thanks for carrying this for me (Y/N)-chan!" Totoko said as she takes the bag that you were holding.
"As for you...." Totoko turns her head towards Osomatsu.
"I cant believe you need a girl to help you carry one last bag!! Its not even THAT heavy" Totoko scolded Osomatsu.

"G-gomenasai...Totoko-chan..." Osomatsu shyly bowed at her.

"Hmph! Next time, bring the other NEETs!" She said before she swipes the eight bags from Osomatsu's hand and slams the door.

Now, walking back home was 90× more awkward than when walking to the flower shop.
"Why did you have to help me? I could've carried it myself" Osomatsu said, without even looking at you.

"Look nii-san, it was obvious you needed help. Look! Your fingers are becoming red from carrying heavy stuff for too long!" You took his hand and looked at the red marks but he quickly pulled his hand away from you.

"Dont tell me...you're mad at me, are you?!" You looked at him in shock, you two kept walking on the sidewalk with many cars driving past on the road beside it.

"I just want to help you!"

"But you embarassed me infront of Totoko-chan!!"

"Why is that such a big deal!? I mean....she always gets mad at you and our brothers, right?!"

"Do you even know why I didnt let our brothers go to the Mall with me and Totoko-chan?!?"

"....."

"Because I wanted to prove to her that she only needs ME to help her, and if any of my brothers are there with us, they'll just either try to steal her away from me or maybe EMBARRASS me like YOU!"

"I...why are-"

"I thought that you wouldnt do anything to make me feel ashamed of myself but I guess I was wrong....You're just an overprotective sister! Y'know I cand do things ON.MY.OWN."

"OVERPROTECTIVE?!?"

At this point, the two of you stopped walking and just started an arguement in the middle of the sidewalk while people were staring at both of you.

"YOU'RE JUST A STUPID ELDEST THAT DOESNT KNOW ANYTHING AND NOT EVEN KNOWING THAT YOUR SISTER IS JUST TRYING TO HELP YOU AND YOU NEVER HELPED HER BACK ONE BIT!!!"

Osomatsu was shocked and  was furious, he snapped and started to push you towards the road.

"Nii-san! W-what are you doing?!"

You tried to push him back but your foot sliped. Osomatsu pushed you onto the road but before you could even touch the ground, something really big and heavy hit you, the last thing you saw was Osomatsu's face filled with disbelief. He couldnt believe what he had done.

The truck hitted you so hard that you got tossed far down the road, as if it couldnt get any worse, the same truck ran pass your now bloody, unconcious body.

You can hear all sorts of sounds, like people screaming at the sight of you, you could even hear people call 911.
But what caught you off guard was Osomatsu, you can just barely hear him.

"IMOTO!!!" He screamed.

You can hear running footsteps going towards you and someone kneeling down next to you.

"Shit,shit, SHIT! (Y/N), please...wake up..."

You can feel tear drops falling onto your face, your mind was still concious but definitely not your body.

You can hear police sirens all over you, it was quite loud.
But none of those sounds could compare to Osomatsu's cries.

OOoOoOooOo CLIFFHANGER :D
Can I just say, the last chapter took me so frickin long to make.
