***********

"We'll be back in an hour!" Jyushimatsu says as he puts on his yellow slipper.
"An hour?! What are you guys doing at Chibita's for an hour?!" You complained to them.
"Havent you heard? Chibita is cutting the price of his oden for 20% off....." Ichimatsu quietly said as he puts on his purple hoodie.

"But its not like you guys are gonna pay for the food anyway, so whats the point?" You leaned up against the wall.
"It means we dont have to pay our tab that much" Totty says without moving his eyes away from his phone. You chuckle.

"You guys NEVER pay your tab" You smile at them, despite the big troubles they get into, you still love them so you dont really care that much.
"We'll pay our tab! Just.....not now" Choromatsu mumbles that last part.
"Aaaawwww but then I'll be lonely here....." You pouted.

"Dont worry sweetie, Karamatsu said he's gonna stay back with you" Osomatsu says before pecking your nose.
"Speaking of which, where even is he?" You look around.

"He's probably on the rooftop playing his guitar" Totty points to the roof.
"Alright then, I'll go check on him. The five of you have fun!" You waved them goodbye after kissing each of them on the cheek. Now to check on Karamatsu.

You walk upstairs to the roof and see Karamatsu strolling his guitar.
"Hey Kara, remember that time where we sang that 'Onaji Hanashi' song together?" You say as you sat next to him. He looks at you with those beautiful eyes, it was always something that you really liked about him.

"You mean the one where we first kissed?" He smiled, you look away all flustered.
"I remembered it perfectly, it was the only amazing thing that ever happened in my life" Karamatsu's voice saddened.

"W-what does that suppose to mean?" You asked with concern,
He looks at you and smiles sadly.

"Its nothing, Karamtsu girl. As long as you're here, Im always happy...." Karamatsu said before placing his lips onto yours, you cupped his cheeks.
The two of you let go of the kiss and locked eyes with eachother, you leaned your forehead onto his shoulder, causing Karamatsu to blush bright pink.

"C'mon, lets go back downstairs, its getting a little windy" Karamatsu says as the both of you got up and went downstairs.

Once the two of you were downstairs, you were pretty hungry so you went to the kitchen and search for food, nothing caught your intrest untill you see (F/S) on the top of the fridge. (Favourite snack)

You tried to reach for the (F/S) but being the short potato you are, you cant even get your fingers ontop of it. You sighed and you were really hungry, you tried to stand on a chair but YOU STILL FRIGGIN CANT REACH IT.

Am I like the shortest human in the universe or do we have such a long refridgerator?!
You got off from the chair all angrily untill you saw at the corner of your eye, a laughing Karamatsu.
"HAHAHAHHA! YOU CANT EVEN GRAB IT EVEN BY STANDING ON A CHAIR?!?!" Karamatsu wheezes.

"Shut up, Shittymatsu!" You playfully wailed at him.
"Do you need my help?" Karamatsu says as he walks closer to you.
"What will you even-UWAAHH!?" Before you could finish what you were saying, Karamatsu hugged your thighs and lifts you up.

"K-KARAMATSU NII- SAN!!!" You screamed, your face as red as a tomato.
"Heh, calm down! I've got you....." Karamatsu tried not to scream from fanboying that he's literally picking you up.

"O-okay.....ermm.....get the (F/S) already...." Karamatsu said, trying his best not to touch 'The upper part' of the thighs.
You reach to the (F/S) and once your hand was just a few inches away from the (F/S), I guess Karamatsu lost his concentration and fell as you fell ontop of him.

You landed on his chest, now the two of you looked at eachother, your fingers on the spot somewhere near his stomach. You could actually feel a little bit of...............abs.............

"N-nii.......san?" Was all you could say before Karamatsu cupped your cheek with one of his hand and held the back of your head with the other hand and slowly pushes your head forward to his, as you two shared a makeout session.
After awhile, Karamatsu's hand lets go of the back of your head and up your hoodie.

"K-Karamatsu nii-san!" You yelped at the feeling of his hand on your back.
"S-sorry, I went a little overboard" Karamatsu apoligized.
"No....its.....its fine heh...." You look away, refuse to look at him.
"Do you......want to stop?" Karamatsu asked as he places his other hand under your chin, forcing you to look at his seductive eyes.
You gulped.

"N-no...." You barely said above a whisper, at this point your face is crimson red.
"Good Karamatsu girl, cause Im just getting started~" Karamatsu says as his hand started moving from your back to your chest.
You let out a little whimper.

"Shhh its okay my Karamatsu girl, since this is your first time, I'll try to be gentle....." Karamatsu whispers in your ear, making you flinch.
Karamatsu positioned himself so that it'll be comfortable while you did the same, now you were laying on the floor while Karamatsu was ontop of you.

He started caressing your chest, gentle as he promised. Then you felt a little impatient after awhile, you realized that he was teasing you.

"N....nii-san, stop t-teasing me...." You whimpered.
"Heh......fine, fine......" He said before he started to massage your chest, it was actually pretty nice.
But when you thought that nothing would go wrong, Karamatsu suddenly squeezes one of your boobs.

"A-aah.....Ka-Karama..." Before you could finish what you were saying, Karamatsu planted a kiss on your lips.

"Dont worry, I'll make sure that you'll never forget this moment we had with eachother, my Karamatsu girl~♡"
