Unexpected Discovery (Karamatsu x reader)

Karamatsu and I were not speaking to each other. His family was concerned because Karamatsu and I were the best of friends, I was friends with all of them but was closest with Karamatsu, and we suddenly stopped talking to each other. So naturally they were worried. Choromatsu had approached me early today and asked "what happened between you two?" I look down at the question and turn away.

"He didn't like...make any advances towards did he?" I shook my head "n-nope...it's worse than that." I say and from that point on the brothers tried to fix it. They tried and tried and tried until they had enough. They push both me and Karamatsu into their bedroom and said they weren't letting us out until we fix whatever happened between us.

"How are you going to keep us here? You can't even lock those doors!" I shout and Osomatsu smirks "we have our ways." He says before slamming the door shut. Sure enough when I tried to open the door it wouldn't budge. I turn to see Karamatsu who avoided eye contact with his mouth forming a line.

I look away and walk over to the couch while he went to the corner in the opposite side of the room. Now at this point you may be wondering what the hell happened. Well it's kind of an long story but it all started on a day when Karamatsu and I had his house to ourselves.

Flashback

Karamatsu and I were just sitting at the living room table bored out of our minds. "Do you wanna talk about..whatever?" I ask and he hums "how about (favorite show)?" I perk up and nod. So we got into a civil friendly chat about one of my favorite shows on TV. But then we had a disagreement. Which lead to us arguing and verbally fighting.

Then he messed up. In anger he spoiled me about something bad that happens to my favorite character. So I let out a scream of anger and lunge at him. He ducked out of the way but I got up and pushed him to the ground. I honestly didn't mean any harm but he spoiled me. About my (favorite show). So I was currently smacking his face.

He gave a growl and reached up to pull my hair. Yes we fought like siblings, not his brothers because they are really aggressive, but normal siblings when they fight. I turn my head and bite his wrist. He let's go and held his hand. He went to sit up but I push him back, my hands on his throat. Was what I'm about to do too far? Maybe but to be fair if you start a fight with me I will do this. Ask my own older brother.

So I place my hands around his neck and tighten my grip. He gave a choked gasp and his legs were kicking behind me. He reached his hands up to try and pull my hands off. His cheeks turned red as he desperately claws at my hands while gasping. I wasn't going to keep doing this till he passed out, no I was just going to do it tell he learned his lesson. I saw his eyes roll back before becoming lidded and I tighten my grip a little but immediately stop.

He moaned.

Karamatsu was moaning as I was choking him. It wasn't like a moan of pain either, no he let out a moan of pure pleasure. Then I took in his face. Lidded eyes that were rolled back, mouth open as he pants, and heavy blush on his face. To make it worse I felt hardness underneath me. He was turned on by this.

He had a choking kink.

I blush and let go of his throat. He immediately gasps and coughs for air he then glanced up at me with those lidded eyes.

"Y/nnn"

I blush at the whine in his voice as he drawed out my name. "I..I'm S-Sorry!!" I shout and jump off him before leaving the house, running away from him.

Flashback over

Yeah..so now it's just awkward and neither one of us know what to say to each other. Though after 5 minutes in this room Karamatsu mumbles something. "Huh? What?" He sighs and hid his face in his hands "I said I'm sorry." I look at him surprised "why are you apologizing?" I ask and he blushed

"I..I knew I had that kink...I'm silent about it because...well it's embarrassing I mean how would you react if I had told you that I have a kink for being pinned down and choked." He says with a pout "so I don't talk about it..they don't even know." He says gesturing towards the door "well they probably know now." I say knowing that the doors weren't exactly soundproof.

He groans softly before standing up "I also don't want this to ruin our friendship or anything...but there was another reason I didn't try harder to stop you." He says and I look up at him. He sighs and looks at me "it felt really good when you did it and to be honest ever since I discovered this kink of mine...I have fantasied about you doing it." He cleared his throat and blushed

"That's why I got turned on...and why I was hard...sorry."

I blush and glance around before sighing "it's..it's okay. To be honest I was mortified because I thought I had made things way too awkward...and my mind was saying how you'd never date me because of the embarrassment." I confess and he looks at me surprised.

"Really?" He asked and I nod before standing to hug him "really really." He hugs me back and hums "um y/n?" I hum out a yeah "does this mean you'll be my girlfriend?" He asks and I could only smile as I look up at him. "Yes, of course." I say before nuzzling my face into his chest.

His smile was something you could never forget as he lifts me up into a tight hug before he spun us around. When he stopped spinning he lifted me up in the air with that soft smile before slowly lowering me down into a kiss. I couldn't help but smile and kiss back.

He was a kind sweetheart of a man who just so happened to have an interesting kink.

It was unexpected discovery but in the future I would be so glad that I discovered it.
