A/N: I am still alive and My brain is dead when it comes to Hetalia fics because I am roleplaying it with my partner every single day. I would record our roleplay if they were'nt shitty. lol

Anyway, This will be my first Osomatsu-san fic. I have been stuck inside Hetalia hell for so long that I found a tunnel to the Osomatsu-san hell. yaaaaayy..

This will be a three-shot fic. Ichikara and OsoChoro, mostly.. I am combining two of my favourite doujins together. This Chapter's content is mostly inspired (and shamelessly copied) from a Doujin called Forbidden Feelings by Choko17. I will tell you guys what the next doujin is later.

Lastly, I suck at entitling stuff. Also, The summary would not be found here in the story lol. Enjoy!

He could not believe it.. Shittymatsu having a girlfriend? It is just ridiculous to think about. He cannot accept it. Ichimatsu clenched on his pants as he thought about it, sitting in the corner of the room. He was a little thankful that his brothers were absorbed to themselves at the moment. They would not be any more helpful if they both him.

Shittymatsu, what the hell are you up to? He asked to nobody in particular. He sighed and stood up. He slipped his face mask up to his nose bridge and muttered. "I'm gonna take a walk." The others looked up at him.

Choromatsu, his most responsible brother, frowned slightly. "Will you be out late too?"

Ichimatsu shrugged. "It depends.." He muttered lowly.

Osomatsu rubbed his index finger below his nose. "Just don't get mugged on the way. That's gonna be a pain in the ass.. and not the good kind." He snickered to himself.

Choromatsu grumbled. "You're impossible." He went back to the idol magazine that he was reading.

"Awww~ Chorooo~ What's wroooong~?" Osomatsu whined as he crawled towards Choro.

Choromatsu replied huffily but Ichimatsu did not bother to listen to it.

Jyushimatsu literally bounced on his seat, waving him goodbye. "Take care, Ichimatsu-niisan~!" He beamed before turning back to the television while Totty waved at him without looking up from his phone.

Ichimatsu huffed and slipped on his purple slippers. He made his way out of the house and walked to a random direction. He looked around the people around him. Of course, he was trying to find his own brother in the crowd.

Ichimatsu was frowning as he made his way to the park. He could not find his brother anywhere. He tried the cafes and the convenience stores but he was not there. Where is he meeting her? He gritted his teeth in annoyance. He held himself back for too long to give up now. There is no way any random girl is going to take Karamatsu away from him.

"Aaah~!"

A vocal sound stopped him from his thoughts. What was that? He stopped walking to look around.

"Yes~ It feels amazing~"

His brows furrowed. Some one is having sex in this public area? Seriously?.. Well.. I have to admit that it would be pretty hot..

"Aaah.. Yeah… Cum inside me.. please.." The voice became more familiar.

Ichimatsu's eye widened. That voice. He frantically searched for the source of the sounds… Then found it. His world stopped and crashed in front of him.

Karamatsu.. His brother whom he loves and cares for no matter how hard he tried to deny it.. is being fucked in front of his eyes.

His knees felt weak. He leaned on the tree in front of him. He noticed that his own fingernail have dug on the bark of the tree. Who is this person? Who is fucking his brother?

Karamatsu seems to enjoy it. He could not see his face since his back are turned on him but he knows that he was enjoying it. He is making all these lewd noises and his ass is making sloppy and wet sounds. The man behind Karamatsu came inside his precious little hole, making his brother cum on the grass and the tree before them.

Ichimatsu let go of the breath that he just noticed that he was holding. His lips hurt from being bitten on as well. He want to be the one.. The one to fuck Karamatsu in a public park late at night. He glared at the unsuspecting man who has slipped his cock out of his brother.

"Well... That felt really good, Karamatsu.." The man said as he zipped up his pants. "As usual, you could call me anytime you want to do this again.."

Ichimatsu's eyes widened once more. Karamatsu wanted this? That fucking Shittymatsu wanted this man to do all this shit on him?! His nails dug deeper into the bark of the tree. His head was going crazy. Why? Why him?! Where did he even meet this guy?!

He did not notice that the man already left Karamatsu after the two freshened up. Fortunately for him, he walked to the opposite direction from where he was. He stared at Karamatsu, silently demanding answers from his shaking form.. Wait.. Shaking..? He gasped softly as tears fell down from Karamatsu's eyes. He is crying.. Sniffling to himself... Why..? What does this mean? He was enjoying earlier.. Why is he crying now?..

Karamatsu...

Karamatsu continued sobbing until it reduced to mere hiccups and sniffles. He needs to step in. He is still confused (and a little hard) but he does not want to leave Karamatsu alone in the dark park. Who knows what will happen to this idiot?! He lowered the face mask down to his chin and strategically lowered the hem of his hoodie to hide the bulge on his crotch. His hands are inside the pockets. He slowly walked towards Karamatsu until he was two feet away. The other still haven't noticed him.

He mustered all the courage that he could manage and spoke up. "...Oi... Shittymatsu.." he clicked his tongue. Well, the sounds fucking perfect. He thought to himself.

Karamatsu flinched and raised his head up at him. Ichimatsu swore that there was a blush on his cheeks. Why would he blush? Was he embarrassed? Karamatsu jumped up on his feet, wiping his face and pushing his sunglasses up to the bridge of his nose. He hates those stupid things. Who wears those at night?!

"Heh. Good evening, brother~" Ichimatsu wanted to punch this guy so hard.. And maybe hug him afterwards. "ah~ a stroll late at night? Truly~! You are learning how to be like me!"

Ichimatsu frowned at him deeply. "Shut the fuck up. What the hell are you doing by the tree? Crying?"

He noticed that the other paused in hesitation before smiling. "I was just admiring how these wonderful trees give us life~ Oxygen, was it? Ah, Yes! A natural source of oxygen to be breathed in by handsome men like me- Like us~ since we have the same face~!"

Ichimatsu's eye twitched. Alright. That is it. Enough with this pretend from a former drama club member. He glared at him as he stepped towards him. He grabbed his shoulders and pinned him to the tree. "Do not fuck wih me, Shittymatsu!" He could feel his ears, chest and eyes burning from anger and frustration.

Karamatsu looked so startled, staring at his brother with a confused look. "w-what do you mean, brother?"

He growled. He wanted to pretend that he did not see anything. So he would explain everything. But he had it. All that waiting. All the shit he has gone through. He would not let it go to waste. "Stop it. Stop with that fucking facade, you crappy piece of shit! Who was he? What were you thinking having sex with someone the rest of us don't even know?!"

Karamatsu's eyes widened. His sunglasses slipped down slightly, revealing his teary, shaky blue eyes. "W-what?.. Y-you saw..?"

He growled lowly. "I saw, heard and I am fucking smelling it right now!"

Karamatsu blushed deeply. The moonlight is betraying him by showing his scarlet color. He looked away pulled his hand away from him. "..Unhand me, brother.."

Ichmatsu gritted his teeth and grabbed his wrist. "What? Are you running away, Shitty-"

"WHY DO YOU CARE?!" Karamatsu suddenly blurted out, tears falling from his eyes again. This caught Ichimatsu off guard. The younger one's features softened at the sight, feeling a little guilty of the rage that he showed earlier.

Karamatsu sniffed and sobbed. He used his hands to wipe the tears off, ducking his head down. "W-why do you care now of all times..? Y-you really have the worst timing, Ichi..."

Ichimatsu frowned. He wanted to ask what the other meant but he stayed silent, watching the other cry.

Kara continued sobbing and wiping his tears. He took his sunglasses out of the way and hung in on his shirt. "I-I had no choice.. If.. if I do not get myself fucked by someone, I would do something that will disgust every single one of you.." he chuckled bitterly. "Though.. This is not less disgusting.. It is still the better way.."

Ichimatsu frowned. "Better way?" He could not believe his ears. Bright and confident Karamatsu? Beaming, cocky AND painful Karamatsu is crying in front of him..? Sure, he have not treated his precious brother very well but surely, everyone cared for him enough that he would not feel neglected.. Sure, there was this time when he got kidnapped and they ignored the fact that he is gone but he came back that night, still having that stupid grin.. There are times that I have treated him like trash even after he saved me from being caught wearing his fashion.. yet.. he still treats me kindly..

He frowned... I have been really shitty to him, huh.. He shook his head. "Shi... Karamatsu.. Look at me.." he stepped closer to him and lifted his chin up to take a good look at him. His eyes were puffy, red and wet. Somehow, the tears glistened because of the moonlight. His nose was a little runny that caused the sniffling and his soft lips are trembling, pressing themselves together.

... He looks so beautiful..

He always knew that but seeing him weak like this makes him want to protect this stupid guy from hurting himself... If only he is crying because his cock feels good inside him, crying out his name and-

Okay, not now. Stupid, disgusting, trashy head of mine..

He huffed and frowned at him. "Look.. Whatever it is.. No matter how shitty we are to you.. We will never be disgusted at you.. We will be hurt from you painful fucking lines but.. We are still your brothers.. Tell us.. Whatever they are.. No matter how fucked up you are.. Besides, I am the most fucked up among all of us. How bad can it fucking be?" he sighed and pulled his in to a sudden, awkward yet warm hug.

Karamatsu felt himself tearing up again. But only because of happiness this time. He gasped and looked at the other when he was hugged. "I-Ichi?"

Ichimatsu huffed. "Savor it while it lasts. It might be the last time for me to do this..."

Karamatsu blushed once more and smiled. He closed his eyes and hugged his younger brother back. "Ichi... thank you..." he bit his lip and hugged him tightly.

Ichimatsu stiffened. Oh shit.. Karamatsu is being adorable! FUUUUUUUUUU- He can't- He just- Fuck, he is getting sweaty. Fuck, no! He gritted his teeth and pulled away from the hug. "O-okay that's enough.." he cleared his throat.

Karamatsu chuckled and smiled at him. "Thank you, brother..." he looked away and wiped the rest of the tears.

Ichimatsu watched him from the corner of his eyes and cleared his throat before looking away. He stuffed his hands in his pockets. "So...? Who was he?..."

Karamatsu looked down and sighed. "Let's talk about it while we walk home, brother. I cannot make our other brothers worry after all. That would be insensitive of me.."

Ichimatsu raised a brow. You made ME worry, you fucking idiot. He wanted to say but he does not want the other to feel bad again. "Fine.." he turned to walk home with the other side to side.

After a while, Karamatsu finally spoke up. His head was ducked down. "I-I have sexual frustrations lately... So.. A month earlier.. I tried to drink it off at the oden stand.. Then.. Suddenly.. This man sat beside me and we started talking.." he smiled a bit. "I actually had fun talking with him.." his small smile turned into a frown once again. "... Then he suddenly asked if I could tend to his curiosity.. About.. Same sex intercourse.."

Ichimatsu almost snorted at the term that Karamatsu used but he stopped himself. He is too angry and jealous at the moment to mock him.

"I was lost for words.." Karamatsu continued. "... So I drank and drank instead.. Until I got too drunk and agreed.. We went to this hotel and.. I did it with him for the first time.. It felt good.. But it is not what I really wanted.. At least my sexual frustration is a little tamed..." he bit his lip and took a deep breath. "It was tamed for a very short time.. So I called him again and again... I.. I always feel disgusting afterwards, Ichi.. I am only using this man.. For my sexual frustrations... it is the worst.." Karamatsu lowered his gaze and chuckled bitterly. "I am really a sinful man..."

Ichimatsu kept his frown. He did not notice at all.. He feels so worthless now. One of his brothers and the most important person for him have these problems and he did not notice... He hates it.. He hates himself. He stopped walking and looked down on the ground. He had enough.. He had enough of holding back.. He does not care anymore.

He grabbed Karamatsu's hand and walked swiftly to get in their house. Karamatsu stumbled after him, whispering to him, questioning his actions. Ichimatsu ignored them as he took his slippers off by the entrance. He stepped inside but Karamatsu pulled back his hand. "W-wait! It would be rude to dirty the floor..!" he whispered before struggling to get his shoes off in a hurry, placing them neatly on the side.

Ichimatsu grumbled. "Neat freak." he mumbled before pulling him once more, heading to the bathroom. He closed the door and locked it.

Karamatsu stumbled once more and stared at Ichimatsu in confusion. "Oi, Ichimatsu, what are you doing-" He gasped as his sentence was cut off by his brother's lips pressed against his own. "m-mmn..!" he grabbed onto the other's arm and clenched on his sleeve. Ichi's lips felt so good on his. He let out a small mewl before closing his eyes.

Ichimatsu took this as a sign to continue so he nibbled on Kara's lower lip and sucked on it, biting on it as well. He made sure that it would be red and swollen. His right arm slithered on his waist and his own body pushed him against the cold tiles. His left hand pinned the other's wrist on the wall.

He probably lost all of the sanity that he have left because his head feels numb and hot, his breath is ragged and he is grinding his hips madly on his older brother's crotch. But none of that could compare to the feeling of Karamatsu's lips kissing him back desperately, his arms wrapping around his neck and his hips grinding back at him.

Oh God, he's such a slut. If he only knew that he would react this way, he would have done this a long time ago. He will be the one to satisfy his libido.

This only made his cock twitch. He growled and pulled away after biting his lip. He leaned in to whisper on his ear. "You should let me take a good look at you, Karamatsu-niisan.."

Karamatsu stopped his moan half way. His knees are shaking and Ichimatsu could clearly see his boner under his pants. "B-but Ichi.. A-aren't you disgusted..? W-we're brothers.."

Ichimatsu clicked his tongue. "I do not care right now. I just wanna fuck you, Shitty matsu.. Besides.. We're both trash. This is not the worst thing that we can do." He smirked widely. "Now, let me undo your pants."

Karamatsu is already deep red. He almost immediately unzipped and dropped his pants as well as his underwear. He put the aside. He lifted his shirt up a little. "I-ichi.. I'm so sorry.. Your big brother is so lewd.."

Ichi only chuckled at that. "I will only make you more lewd, Karamatsu-niisan.." He said as he undid his own pants, letting his rock hard cock bounce free.

The older one drooled at the sight and gulped. He quickly wiped his drool in embarrassment.

Ichi chuckled. "Oh? Looks like someone wants something in their ass."

Karamatsu blushed and whimpered a bit. "I-ichi.. Y-you're scaring me a bit.."

The younger one let out a low chuckle. "I do not think you really are.." He stepped closer to him and lifted his blue shirt before leaning in to lick around his nipples as his index and thumb roll the other.

Kara gasped and moaned before covering his mouth to stifle his moan. He knows that he should not wake the others but Ichimatsu didn't care. He is enjoying the shit out of his bIg brother's body. There is no way he would stop now. Besides, the thought of being watched turned him on some more.

He bit on his older brother's hard, red nipple before sucking on it and licking around it, abusing it along with the other nipple which is being pinched, pulled and twisted.

Karamatsu whimpered and said that it hurts a bit but his cock is twitching. Heh. He is a masochist after all. Ichimatsu took this as good news.

He pulled away from the nipple only to lick around the other. His right hand slid down from Kara's chest to his stomach, then to his groin. He teased the older one's tip before pumping it.

Karamatsu's moans have gotten louder. His other hand is above the one that is already on his mouth. His eyebrows are furrowed as always but his eyes are rolled up in pure ecstasy. His hips started to buck on their own.

Ichimatsu took a long look at the sight and licked his lips. "You're acting so cute today, Nii-san." He whispered on his ear. He noticed that a lot of pre-cum flowed out from his brother's twitching cock. He scooped some amount of the fluid with his hand and spread his brother's legs. He started fingering him. He frowned when he felt some cum of the nameless guy that fucked his precious brother.

"Oh, Karamatsu~" He smirked and grabbed his brother's chin to make him look at him. "The moment I ram my hard cock in you, I will make sure that you forget him, his name and whatever he did to you."

Kara, who was a panting, hot mess, looked into his brother's eyes. He moaned out and hugged Ichi's torso. "I-ichimatsu.. Make me forget his cock.. P-please.. F-fuck me..~"

That was all Ichimatsu needed. He pushed his hard, throbbing member inside Karamatsu's twitching entrance. Ichimatsu groaned. Fuck, He is still tight. And shit! His warmth is making me crazy!

Karamatsu gasped and arched his back in pain and pleasure. He yelped out loud but Ichimatsu covered his mouth. He looked at Ichimatsu with an apologetic look.

Ichimatsu's hand was shaking. He was trying to hold back a bit. He smirked at him. "Now, now.. If you do not want to be caught, stuff something in your mouth and hold on to it."

The older one nodded and quickly found a white handkerchief in the pocket of his leather jacket. He crumpled it and stuffed it in his own mouth.

Ichimatsu smirked and grabbed under Kara's rear before lifting him up and leaning his back on the wall. He started bucking his hips, pulling most of his cock out, stopping below the tip before slamming back in and repeating the process.

Karamatsu squealed on the handkerchief as his head threw back, almost hitting his head on the wall. His eyes rolled upwards and his eyes lidded. His nails were dug on Ichimatsu's skin as his ass his being fucked. His moans are mostly being blocked by the handkerchief.

Ichimatsu continued ramming his cock as he bit on his brother's collarbone, sucking and making angry, red marks. He hummed and started thrust harder and faster, trying some angles to hit Karamatsu's spot.

Once he did, Karamatsu arched his back, his eyes became wet and he bit on the poor handkerchief. He made a long moan and bucked his hips. Ichimatsu could tell that he is enjoying this, more so than earlier. He smirked proudly to himself.

Kara's moans got louder and louder as his nails clawed on Ichi's skin. His cock twitched and released its load on their stomach and chests.

Shortly after that, Ichimatsu came inside Karamatsu as well. His hot, thick cum dripped down from his brother's anus. This only made Karamatsu shiver in delight as he breathed heavily, leaning on the wall.

Ichimatsu panted and looked at Karamatsu before pulling the handkerchief out of his mouth. Karamatsu's tongue was hanging out and his drool dripped down his chest. He did not mind it as he leaned in for a sloppy, yet hot kiss.

Karamatsu kissed back lazily as he was out of it. He already had sex for the second time and both were intense, even though he loved it more with Ichimatsu.

Ichimatsu pulled away and continued hugging Karamatsu for a while as he catches his own breath. Karamatsu only cuddled back in content.

After a few minutes, Ichi pulled away and slipped his cock out of Karamatsu. He kissed his cheek before looking into his eyes. "Can you stand? We need to clean up first.."

Karamatsu snapped out of his daze before nodding. He grabbed some tissues to wipe their cum off his chest. He also put his clothes on. They would dress into their pajamas later..

Ichimatsu cleaned the floor as well and pulled up his pants. He looked at Karamatsu and cleared his throat. "Oi.. Karamatsu.. I think we need to clean your ass too.. it might.. you know.. on the bed…" He looked away.

Karamatsu blushed and nodded. "Y-yeah.. Good idea, Ichi.."

Ichimatsu chuckled slightly. He needs to hold back again.

After cleaning and freshening up, they put their pajamas on and sneaked inside their shared room with their other brothers and lay down on the bed. It is a good thing that their position is on the far right. They would not be able to wake anyone up.

The two stared at the ceiling for a while before Ichimatsu spoke up, low enough so that only Karamatsu can hear it. "So.. You.. Do not need a random guy to please you, you know..? I will be here to do that from now on.." He huffed. "Who the hell was that guy anyway?"

Karamatsu turned his head to him and shook his head. "I don't think that matters anymore, Ichi… B-because.. I.. This is crazy but.. you know.. I have always wanted to do it with you… even before he showed up…"

Ichimatsu stared at his brother, dumbfounded. W-wait… Th-then that means..- "I was the source of your frustration?"

Kara blushed once more for the night and looked away. "I-I.. Yes.. I do not know when it started but you always appear in my head.. your rare smile, your frown, all of you.. until I had the urge to kiss you and d-do lewd stuff with you… I-I know it is disgusting and I thought you would hate me more than you already do s-so I tried doing it with someone else.. But even then, my head is playing tricks on me. I always imagine that you are the one making love with me and not that guy.." He is so embarrassed at the moment, he refused to let the other see his face.

Ichimatsu flushed and is now completely red. His mind is now ringing. Wait- I hear wedding bells. What the fuck?! What?! What is happening?! Karamatsu wanted to fu- wait- MAKE LOVE with me all along?! And I didn't know?! I held myself back for nothing! WHY NOW, KARAMATSU? WHY ONLY NOW?! KARAMATSU, YOU ARE BEING CUTE RIGHT NOW! FUCK YOU, KARAMATSU! DIIIIIIIIIIIIIIIIIEEEEEEEEE!
