Osomatsu san x Sister!reader

(8) Hangin' with the 3 youngest

You were reading a book, minding your own business.
Until you hear three of your brothers going to the front door.

You put the book down beside you
"Nii-sans? Where are you going?" You asked the youngest trio.

"Playground! Wanna join?" Jyushimatsu said as he wears his yellow slippers.

"Why are.....you guys.....going to...the playground?" You asked them, raising an eyebrow.

"Jyushimatsu is babysitting this kid named Eitarou" Totty said as he looks up from his phone.

"Then what does that have to do with you two?" You pointed to Totty and Ichimatsu.You noticed Ichimatsu looks a little bit....sadder than normal.

"Well, me and Ichimatsu nii-san are trying to...err...find ESP kitty..."
Totty looks at Ichimatsu with eyes of pity.

So that explains why Ichimatsu has been alot more quiet. ESP kitty must've went missing.

"I wanna go too!" You said before quickly putting on your (F/C) slippers.

----------------

Once the four of you finally arrived at the playground, Ichimatsu already started looking.

"Wait for me nii-san!!" Totty called out to the sad man.

You were staring at them for awhile before you could feel someone tugging on your hoodie. You turn to see a little boy with brown hair and a bowl cut smiling at you.

"Are you master's sister??" He asked you.
"M-master? Ermm....whats his name?" You asked the little boy since you dont know who 'master' is.

"Me! Muscle,muscle!" Jyushimatsu popped out of nowhere.

"Oh! Is this Eitarou?" You asked Jyushimatsu, he nods.
"You're so cute!" You turn to Eitarou and ruffle up his hair.

(A/N) : If you dont know who Eitarou is...then go watch season 2 ep 12.

"Master has told me alot about you!!" He jumps cheerfully.
"Like what?" You asked the boy, trying not to cringe at the fact that he calls Jyushimatsu 'master'

"Like how cute and silly and beautiful you are and how hot-"

"Eitarou-kun! I think thats enough!" Jyushimatsu cuts the boy off. At this point you were blushing bright pink.

"Oh! And also, he said that you were his girlfriend!" Eitarou smiles

"EITAROU-KUUNNN!!!" Jyushimatsu's face became purple

"W-WHAAAA???!" You yelled, you slowly turn dark red.

"By the way master, when was the wedding again?" Eitarou looks innocently at Jyushimatsu, who was now as red as you were.

"Eitarooooouuuuu-kkuunnn....." Jyushimatsu crawled up into a small ball.While you were just.... at lost for words.

"I now present you two...HUSBAND AND WIFE!" Eitarou said as he pretends to be a priest.

"WHAAAA?!?!?" You and Jyushimatsu yelled at him, Jyushimatsu gets up and looks at you.....oh boy.

"I-ignore him Imoto, he's...uhhh just being an idiot" Jyushimatsu chuckles awkwardly.

"C'mon master! Kiss!kiss!kiss!kiss!" Eitarou continues to chant 'kiss'.

"Eitarou....d-dont say it out loud...people can hear you..." You said, embarassed.

Thats when the other people around heared Eitarou chanting and JOINED IN TOO!

Now the whole playground(even the kids) are chanting 'kiss!kiss!kiss!' At you and Jyushimatsu.
The two of you looked at eachother, sweating crazy. But y'know what? There was no other way to settle this.....so you made your move and kiss him, you can hear people shouting 'YAAY!' or maybe even clapping.

You pulled away from the kiss and Jyushimatsu's face was as red as ever. Jyushimatsu falls to the ground, I guess you could say he's 'lovestruck'

You ran away from the playground, covering your red face with your hands.

Thats when you bumped into someone, causing both if you to fall. You look to see it was Ichimatsu.

"H-hi Ichi! So...umm..have you found ESP kitty yet?" You said, trying to fan yourself.
Ichimatsu shakes his head.
"W-where's Totty?" You asked him. He shrugs
"Errmm...c'mon, lets go search ESP kitty together!" You said before grabbing his hand and drag him.

----------------

Its been 10 minutes and you still havent found ESP kitty, you can tell that Ichmatsu started panicking. You caress his back to reassure him.
"Its okay, nii-san. We'll find them soon...." You tell him with a soft voice.

"You really think so,Imoto?" A diffrent voice was heard, it sounded like something that Ichimatsu would say, but he kept his mouth shut the entire time....

That means......

"ESP kit-" Ichimatsu said as he turned around and before he could finish his sentance, he already ran up and hugged the orange cat.
"Yaaay!! We found them!" You cheered and crouched next to Ichimatsu.

"Thank you so much (Y/N), for helping me find them" ESP kitty said as Ichimatsu looks at you with a smile, you chuckled.

"No problem!" You smiled.
Thats when Ichimatsu cupped one of your cheeks with his hand.
You can feel yourself getting red again. And just like that, he slowly moves his head closer to yours as you did the same to him.

and you two shared a kiss....to be honest, somehow, it was kind of romantic and sweet.

---------

You two went back to the playground to look for your other brothers, and fortunately, they were there. It was 5 o'clock and most people in the playground already left.

Jyushimatsu and Totty's eyes lit up when they saw Ichimatsu holding ESP kitty.

"OH THANK GOD! I thought that cat was DEAD FOR SURE!" Totty lets out a sigh of relief, while Ichimatsu glared at him.

"What were you two doing while we were gone?" You asked the two.
"We were betting porn magazines on who's the better kisser!" Totty gave Jyushimatsu an Im-so-gonna-win-that-bet kind of look.

"And whoever wins the bet, will get to have the other persons porn magazine!" Jyushimatsu puts his hands on his hips.

"But who will know who's the better kisser?" You asked them, ignoring the 'porn magazine' part.

"We were just talking about that!" Totty folds his arms.
"Y'know what,Totty? I think im a WAY better kisser than you" Jyushimatsu teased him.

"Excuse me?!" Totty sounded offended. For your whole life knowing Totty, you knew he doesnt like losing or getting teased.
"Might aswell you give me your magazines now, muscle!" Jyushimatsu continued teasing the now angry man.
"I'll prove you Im a better kisser!!" Totty shoved the tip of his index finger on Jyushimatsu's chest.

"How? There's no one here you could kiss is there? And besides, you always go to those mixers but you never seem to get atleast ONE kiss from a girl?" Jyushimatsu made a funny face at Totty, which made him more angry.

"GRRRR! THAT'S IT!" Totty yelled at the yellow man before tugging on the collar of your neck and kissed you, you became dark red, you were pretty sure that you can even feel his tongue touching your bottom lip which made you more red.

"MHMHFF!!" You muffled.

Ur expression >  0//////0   ♡ ♡ ♡ ♡

Totty pulled away from the kiss.
"See,Imoto?! Im a good kisser right?!" Totty asked you but you were too flustered to even say anything.

"You do realize you kissed Imoto right, little brother?" Ichimatsu said, tapping Totty's shoulder.
"W-wait...........WHAT THE?!?!" Totty realized he just kissed you and now is flustered like you.
"YOU PLANNED THIS, DIDNT YOU?!" Totty turns to Jyushimatsu who was pretending he didnt do anything.

"Lets just....g-go home...." You muttered
