Work Text:
It was pretty unusual to have so many males live under the same roof, but they managed simply because of the fact that they were all brothers, and thus were the exception to things like territory and the vicious defending of such, among other things.
It was sometimes difficult, though, at least in the beginning it was when they were all finding their place in their house, rank-wise. Osomatsu, the first born, who also happened to be an alpha easily took the title of Dominant, and everyone else just had to fall in place.
Karamatsu was a beta, and Choromatsu ending up being one as well. The latter brother soon became Osomatsu’s obvious favorite, and despite Karamatsu being technically the second-oldest, Choromatsu was quickly flung up into the ranks among them for being so close with the eldest, most dominant brother.
That was fine, Karamatsu thought. It probably wasn’t any fun waiting on Osomatsu anyway.
Jyushi was also a beta, and for a while it seemed as though only the eldest of their sextuplet group would present as anything other than average beta of all things, because even Ichimatsu was suspected to also be a beta.
Turns out that Ichimatsu was actually a late bloomer, and the day everyone could scent what he actually presented as was a day most of them wouldn’t forget, as Osomatsu was very, very quick to re-establish his dominant-brother title.
Ichi had presented as an alpha, and their parents were quick to put him on suppressants lest they wanted to lose one of their six children at the hands of each other.
Ichi wasn’t a beta, but he had thought he was in the beginning, and even when he turned out not to be, he was forced to live like one anyway. The suppressants, coming in many forms over the course of their lifetimes (pills, lotions, injections, there was no end) took their toll on Ichimatsu’s body, seeming to eventually render him perpetually tired and apathetic and sometimes even ill, which worked out perfectly for Osomatsu who no longer had to worry about his place among his brothers being threatened.
Todomatsu was also a late bloomer, it seemed, and it was only to be expected that out of six children, with one already presenting as an alpha, there was bound to be an omega. Statistics didn’t lie. This day and age, science said that at least one child out of four would present as something other than beta, and the Matsunos had bore six children. It was just math from then on.
Osomatsu seemed to take special care of Todomatsu, and so did everyone else, too, having been raised with the idea that omegas were delicate, rare, fragile creatures who needed to be treated as such.
Karamatsu had to disagree, because eventually Todomatsu had become so damn spoiled that he was easily the most vicious out of the whole six of them, being rather clever and manipulative just to get his way, and it always worked because he was oh-so special . That, and Osomatsu seemed to always take his side, and they all had to listen to their eldest brother.
Things didn’t change for years after that. The beta brothers didn’t need to worry about such thing as heats and scents and other stuff like that as much as their eldest and youngest brother needed to, both of them having been put on their own type of medication to control their heats when they did happen, at least until they were ready to settle down with someone for the rest of their lives.
That wasn’t happening anytime soon, though, it seemed, and Karamatsu didn’t know whether or not he was grateful that they could all stay together a little bit longer, or if he was frustrated at that.
No matter.
“Change the channel, I don’t want to watch this show again ! This is the third time this episode has come on in the past week! It’s getting old.” Karamatsu complained as they all sat in the television room, all six pairs of eyes glued to the screen, Osomatsu holding the remote of course .
“I don’t know what else is on that isn’t a re-run.” Osomatsu commented back, clicking through channels.
“Wait! Go back! I liked that one!” Jyushimatsu spoke up, pointing with his too-long sleeve towards the television.
“Which one?” Choromatsu asked, leaning against Osomatsu idly. They always sat near each other, and Karamatsu tried not to be envious.
“Someone just find a movie.” Todomatsu exclaimed, clearly unimpressed with the situation at hand, even though they hadn’t looked up from their phone once this whole time.
“There are no good ones out.” Karamatsu said, watching as Jyushimatsu tried directing Osomatsu to which channel exactly he saw his favorite show on.
“Maybe we should just toss the TV out.” Ichimatsu piped up, albeit quietly.
“That sounds like a good idea.” Karamatsu agreed, getting rather tired of fighting over channels and finding nothing to watch all the time. Thankfully, though, he was sitting several seats away from Ichimatsu, so the glare he got after he spoke was the worst that happened. Karamatsu did his best to ignore it, which wasn’t hard because a low growl echoed through the room and stilled them all on the spot.
“Shut up!” Osomatsu grumbled, and it was mostly instinct that told them all to do exactly that while he fiddled with the remote some more and eventually settled onto a channel that apparently pleased their yellow-clad sibling.
The tension slowly ebbed away, and Karamatsu felt his own shoulders release their tension at the same time Choromatsu resumed leaning idly against Osomatsu. Todomatsu resumed texting and Jyushimatsu was able to enjoy his show in full.
Ichimatsu, however, left the room as soon as he could. This was a usual occurrence, because Ichimatsu’s muted alpha nature was still very much there , and thus it probably really did not like being bossed around without so much as a word in protest.
Just another usual night at their house.
Discomfort, tension, difficulty and all.
☁ ☁ ☁ ☁ ☁ ☁
There were slip-ups, though. There always were going to be. Having two alphas under the same roof that didn’t settle each other’s differences themselves and instead had their statuses decided for them (in this case, by their parents early on) was always a bad mix.
So of course there were going to be accidents. Accidents like Ichimatsu forgetting to take his pills on time, or forgetting to renew his injection appointment, or forgetting that it really was not okay to growl at any one of them, much less Todomatsu or Osomatsu.
Ichimatsu was always quick to be forced back into his designated place, either by the rest of his brothers before Osomatsu got home, or by Osomatsu himself. The latter usually took the rest of them to separate the two raging alphas and hold them apart until they could get Ichimatsu to take his emergency pills and then send him on his way to the nearest doctor for his tri-monthly injection.
There were going to be accidents. All of them knew that much, and after their previous experiences, all of them, sans Osomatsu himself, always had their senses working overtime if Ichimatsu was nearby, just in case. It became routine, and Karamatsu wondered if that was why Ichimatsu was so quick to distance himself from the rest of them, feeling more like a ticking time-bomb than a human being.
Karamatsu felt guilty, and he was sure the rest of his brothers did about having to be super cautious around Ichimatsu as well, but it’s just what had to be done, to keep their household working. To keep everyone safe. To keep everything okay .
Despite their combined efforts, Ichimatsu always seemed to slip off the radar sometimes, and then an accident would happen.
Just like one was happening now.
Karamatsu should’ve noticed it. Ichimatsu’s temper with him was extra short right before these things were to take place, almost like a warning, but Karamatsu had gotten so used to Ichimatsu’s bullying that his mind didn’t immediately recognize that this time was different.
It was only when Ichimatsu had Karamatsu’s hoodie in a white-knuckled grip, pulling the blue-clad brother just close enough for Karamatsu’s dulled senses to catch on, did Karamatsu finally, finally realize.
Ichimatsu’s scent drifted into his nose, a normal occurance as most of them identified each other by their individual scents, but this time, like everything else right now, was different .
Ichimatsu’s scent was strong, and it was building. It was a mix between what Karamatsu could only describe as earthy, animalistic, and heavy .
“Ichimatsu, you--” Karamatsu began, but he was quickly silenced as he was given a quick shake.
“Shut up !” Ichimatsu snarled at him, the low hum of a feral growl riding his vocals in a way Karamatsu had only ever heard a few rare times before now.
Karamatsu immediately snapped his mouth shut, but when he wasn’t released immediately, he spoke again. “We need to get your--”
“I know ! I know!”
The scent was getting stronger, and Karamatsu was grateful it was only he and Ichimatsu in their house currently. Their other brothers had gone off to run their own errands, and he was sure that would take a few more hours. Just enough time to get Ichimatsu to take his emergency suppressants and then air out the house before Osomatsu got back and noticed.
It was then that Karamatsu was thrown to the ground, and Ichimatsu turned and rushed out, heading in the direction of the bathroom. Karamatsu had to take a minute to gather himself before he could get up and follow after his brother, stopping to open the few windows he passed by on the way.
The bathroom door was shut nearly completely, a sliver of space being left behind and Karamatsu was quick to enter. However, he was immediately halted to a complete stop as Ichimatsu’s scent hit him like a damn brick wall , momentarily dizzying him until he could get ahold of himself.
“Did you take your--” Karamatsu asked, raising a sleeve to his face, covering the lower half of it to try and mute the smell. He was cut off, though. Again.
“I don’t have any more.” Was Ichimatsu’s low reply, and Karamatsu blinked, taking a minute to look at his brother who had his head resting on his arms against the sink, trying to even out his breathing.
“You…” Karamatsu started. “You don’t… have any more? Like, at all ? None?”
He saw Ichimatsu shake his head against his arms, and Karamatsu felt something heavy drop in his stomach.
“What are we… what are we going to do? The doctor’s are closed right now. We have to wait until tomorrow morning--”
“I know that, Shittymatsu!” Ichimatsu growled out, raising his head to look over his shoulder at his brother, glaring daggers. The action sent a jolt down Karamatsu’s spine, and for a moment he had the instinct to run -- but he had to convince himself to stay. It was just him reacting to the unfamiliar alpha nature, that’s all. Ichimatsu needed his help, even if he didn’t want it, and Karamatsu wasn’t going to abandon him.
“So what… what do we do?” Karamatsu asked once more, truly at a loss. “We can’t hide you until morning. Even with the windows open, without your suppressants they’re going to smell you from the end of the street!”
He heard Ichimatsu grumble, obviously not wanting to really deal with anything right now, but knowing he had no choice. “I could go out. Stay out all night. Come back after I see the doctor.” He suggested.
“That’s even worse!” Karamatsu protested immediately, stepping closer to Ichimatsu’s side.
“How?”
“Do you know how many people out there will smell an unfamiliar alpha scent and come after you? It’s more dangerous than being here all night without suppressants!”
“I’ll kill them all, no problem.”
Karamatsu felt chills run over his skin, because his brother didn’t sound like he was joking, and that worried him.
“No… no there has to be something we can do.” Karamatsu said, sounding desperate now as he looked around the bathroom as if that would yield some sort of answer.
Ichimatsu didn’t seem to talk for a while, seeming to be more focused on his breathing than his brother near him. At least, Karamatsu thought that’s what was happening, but when he took a step closer, he was stopped.
“Don’t.” Ichimatsu immediately said, his voice filled with gravel and tainted with struggle and Karamatsu stared at him over his blue sleeve he was using as a mediocre air filter.
“Huh? What’s wrong? Does something hurt?” Karamatsu asked, concerned and growing frantic by the passing second. He began moving closer, because if something hurt, Ichimatsu would need to lay down--
“I said don’t!” Ichimatsu roared, and Karamatsu couldn’t even follow with his eyes what was happening and before he knew it, he had been pinned against the sink, his wrists being held down against the ceramic by his brother’s clammy hands, tired eyes staring wildly at him.
“What--” Karamatsu started, his heart pounding with instinctive fear, before it finally hit him. Ichimatsu’s thick, heavy scent filled his nose again and his eyes widened even further, breath hitching in his throat as his stomach lurched.
“You’re in… heat…” Karamatsu struggled out, swallowing thickly because his throat was drying out rapidly out of nowhere.
Ichimatsu continued to stare at him, eyes unblinking and more open than Karamatsu had ever seen them before and damn, Ichimatsu was so fucking close , Karamatsu could feel the heat radiate off his brother’s body, and he may as well have been standing at the edge of an erupting volcano.
“Ichi--” Karamatsu began, trying to remove his hands from his brother’s grasp, but he was immediately silenced as a deep growl entered his ears and splintered down the length of his spine and he immediately leaned backwards as far as he could, away from his brother as much as their dumb little sink would allow.
Karamatsu didn’t make any moves after that, simply staring back at his brother with every ounce of fear he felt in that moment having built up from way before, too.
Eventually, Ichimatsu closed his eyes, forcing his ragged breathing to calm as much as he possibly could, and Karamatsu could see he was struggling with even that small of a task.
“Damn. Damn. ” Ichimatsu said to himself at the same time he leaned forward, resting his forehead against his brother’s shoulder.
Karamatsu immediately tensed, his breath hitching in his throat audibly and he knew Ichimatsu was hearing his heart pound rapidly right now.
“How… how long until they get back?” Was Ichimatsu’s first coherent sentence in a while, and it was Karamatsu who struggled to make himself talk so he could reply, focusing too much on the fact that Ichimatsu was still holding his wrists very, very firmly.
“A… a few hours, at least.” Karamatsu said, having to swallow again right after.
Ichimatsu nodded slowly. “... okay.” He said. “We… we have time.”
“Time for what?”
“To fix this before the others arrive. If you’re willing.”
Karamatsu didn’t understand what his brother was saying, because of course he’d be willing to help keep his brother from being killed by his other one! He said as much, with as much fervor, too.
Ichimatsu merely laughed, shaking his head.
“I’m not so sure of that.”
“Of what?”
“You wanting to help me.”
“Why wouldn’t I?”
“You don’t even know what I have in mind.”
“Well-- … well…” Ah, damn, he was right. “It couldn’t be anything worse than watching you get murdered by our oldest brother.”
Another laugh, and Karamatsu was frowning. “You’ll have to be the judge of that.”
“Fine,” Karamatsu said, determined, and no longer caring for the confusion every word his brother was speaking brought on. “What do we have to do?”
It took a moment before Ichimatsu could speak, as if he was deciding to speak at all about any of it.
“We,” he started, and then took another breath. “have to trick my body.”
“... huh?”
“We have to trick it. It’s in heat-- er… I’m in heat, without suppressants, so we have to trick it .” Ichimatsu repeated, and Karamatsu could tell he was struggling to even do that, but Karamatsu couldn’t tell why. At least, not yet.
“Okay, well, that should be easy then, right? So how do we do that?”
Ichimatsu let out an exasperated growl that had Karamatsu tensing up all over again.
“I’m in heat , and I know you don’t have those, but I hoped you weren’t going to make me spell it out for your dumb ass Shittymatsu-self.”
“I don’t… i don’t understand.”
Another sound of extreme exasperation, and Karamatsu flinched when Ichimatsu lifted his head off his brother’s shoulder to instead look him directly in the eye.
“I need to trick my body into thinking it’s mated to something. Someone. Anything, really.” Ichimatsu said, voice trailing off near the end but his eyes didn’t fall from his brother’s face.
Karamatsu blinked. “Tricked… into thinking… it’s mated? How are you supposed to do that?”
Ichimatsu had clearly been bothered needlessly enough by these questions that rather than answering verbally, Ichimatsu did something else instead to get across his point once and for all.
He thrusted his hips forward, and watched as his brother’s eyes widened and then looked down between them.
“Y-you’re… you’re turned on…” Karamatsu said, barely audible.
“Astute observation.” Ichimatsu said, out of patience for this whole situation. “I need to fuck something, basically, to trick my body into thinking it’s mated to someone, so it can fucking stop this heat bullshit long enough for me to see a damn doctor in the morning.” His voice was strained, annoyed, pissed , and he could smell the fear on his brother’s skin.
“See?” Ichimatsu said. “I told you you might not want to help. I told you this might be worse.”
Karamatsu no longer even had his eyes on his brother, his face too hot and red and panicked for him to even really focus on anything other than the words his brother was saying, and even then that was a struggle because his brother was saying some pretty unusual shit right now.
It took a few moments before Karamatsu could bring himself to even think of answering, and during that time Ichimatsu lay his head back against Karamatsu’s shoulder, sighing deeply, hopelessly .
Karamatsu felt his wrists being suddenly freed, Ichimatsu’s hands instead depositing themselves inside his hoodie pockets.
“You should get out of here. Do your best to clear out the smell in the house while I try and wash off in here and see if that helps any.” Ichimatsu offered, speaking against the dark blue fabric, waiting to feel Karamatsu part away from him, which is something he would usually want every other day, but right now, all he did want was right in fucking front of him.
Ichimatsu didn’t expect a pair of hands come to rest on his back into a loud embrace, and he even less expected to hear a small voice speak into his ear.
“O-okay.” Karamatsu said, his voice wavering with unease.
Ichimatsu immediately raised his head to look at his brother, staring, because he knows he didn’t hear him wrong.
“Are you… sure?” Ichimatsu said, wide eyed.
Karamatsu couldn’t meet his eyes, but Ichimatsu watched as he nodded.
“I’m sure.” He says, sounding everything like he was very unsure , but Ichimatsu could tell he wasn’t going to get any other answer out of him.
“Will it… hurt?” Karamatsu asked, and Ichimatsu nearly choked on his own air.
“Wha-- no! I’m not actually going to fuck you! There’s nothing in the world that could get me to shove my dick in your ass at any time, heat or not!” Ichimatsu yelled, watching Karamatsu cringe but also show a considerable amount of relief at the same time.
“But… then how…” Karamatsu asked and Ichimatsu was getting really, really tired of these fucking questions.
“Like this , you dumbass Shittymatsu.” Ichimatsu growled, reaching down and grabbing a tight hold of his brothers jeans and promptly yanking his leg up, hooking his arm underneath it.
Karamatsu gasped as his leg was pulled up and was hooked over his brother’s arm, and at the same time he felt his brother move forward, placing himself between his legs and Karamatsu could feel it-- he could feel his brother’s erection against the front of his own jeans and oh, God .
Karamatsu’s breathing was rapid, his heart pounding from the sheer anxiety and nervousness and unease the situation brought him and his fingers were gripping the edge of the sink behind him.
Ichimatsu noticed this, and spoke up. “Here, put your arms around my shoulders. It might be better.”
Karamatsu rarely listened to him so immediately, but this time his brother did exactly as he was told to without much hesitation, and Ichimatsu was forced to remember that, oh yeah, he was very, very much alpha right now, and no one in their right minds would go against his words lest they have a death wish. Convenient, he thought, feeling Karamatsu’s arms wrap around his shoulders, his brother’s face automatically being buried into the crook of his neck.
Okay.
“Okay.” Ichimatsu said. “Are you sure this is alright?”
“You don’t have to keep asking. I already said I’d help you.” Karamatsu said into his brother’s shoulder.
“Yes, I do have to keep asking, because there’s going to be a point where you might want me to stop, and it’ll be to late. You’re aware of that, right? Right ?”
He could hear his brother’s rapid heartbeat, and wondered of his own sounded much the same.
“I’m okay. As long as we keep our clothes on, I’ll be okay.” Karamatsu said, finally.
Ichimatsu nodded, but he could feel himself growing less and less patient by the second, the body heat of another person this close was driving his control to the brink and he needed that final okay before the idea of asking no longer meant anything to him.
“Alright…?” Ichimatsu asked one more time.
Karamatsu nodded. “Don’t tell anybody about this.” He said soon after.
Ichimatsu hadn’t bothered to answer, because he had quickly thrust his hips forward with enough force to rip a loud gasp out of his brother. It started out with a slow grind, Ichimatsu having enough sense to at least do that much first, but the feeling of friction finally against his erection was doing fast work to rid him of his last bit of rational thought.
At first, Karamatsu stayed still, figuring it was probably the best option. Less struggle meant less time wasted, and he wasn’t even sure how much longer they had left before his brother’s got back, and what if they got back early? What if he and Ichimatsu were caught? What if--
“ Stop fucking thinking. ” a feral voice spoke. “I can smell it on you and it’s distracting .” Ichimatsu said, making no move to cease his own vulgar movements.
Karamatsu nodded, and did his best to listen. No thinking, okay, he could do that. He just had to distract himself. Easy solution, yeah. Yeah. With what, though? How?
Another gasp was ripped out of his lungs as Ichimatsu thrusted particularly hard, probably because Karamatsu was starting to worry again.
Okay. Focus on something else. Something simple.
Like the feeling of your brother’s hard dick rubbing against your crotch. Yeah. That was certainly something to think about. As well as the fact that the more Karamatsu focused on the feeling, the more he felt too, because he was getting hard and-- ah. Ah .
“ Aah--” Karamatsu sighed out, biting his bottom lip as he angled his hips a bit more so his brother was grinding right against him and, oh, oh yeah , that felt pretty good, actually.
Another sigh left Karamatsu’s lips as he felt his brother’s grinding grow a bit more aggressive. “Ichi-- Ichimatsu--” He said, and he began moving his hips in rhythm with his brother’s.
That little action seemed to drive Ichimatsu over the fucking edge, though, because a deep, chest-vibrating rumble of a growl erupted out of him and Karamatsu yelped as his other leg was suddenly grabbed and hiked up and before he knew it, his legs were wrapped around Ichimatsu’s waist with the latter’s hands right on his ass, pulling him forward into his own thrusts and oh, God .
“Aah!” Karamatsu called out, his voice echoing loudly in the bathroom because his face was no longer buried in his brother’s neck.
In response to his moan, Ichimatsu let out another rumbling purr, and Karamatsu curled his toes at the hot tongue he felt against his throat. Without thinking, he tilted his head farther back, letting his brother achieve more access, his fingers gripping the purple fabric tightly, his mind too busy with the thought that maybe they should take their jeans off. Maybe that would be a better idea. They’d be able to feel each other better and maybe even finish faster, too, which would be good.
“Fuck. Fuck. ” Ichimatsu breathed out, a tight coil of heat in his lower abdomen growing white hot and he was so fucking close , he was so fucking close and he could tell his brother was too and fuck!
“Ichimatsu,” Karamatsu moaned out. “ Ichimatsu--” he said again.
The friction of their hips grinding against each other, the feeling of those strong, possessive hands against his ass, a hot, hungry mouth against his neck… it was too much. It was too much, and Karamatsu’s orgasm took him by surprise.
Almost by as much surprise as the bite did. Almost.
Karamatsu’s eyes flashed wide and the mixed feelings of reaching the peak of his orgasm, and the pain that was searing through his shoulder was too much and he yelled out his pleasure and pain, eyes squeezing shut as wetness appeared at the corners of them and his body shook .
He barely registered the loud, earthquake-like growl that rumbled between them as his brother hit his edge also, having achieved it the instant his teeth met Karamatsu’s flesh.
They were both breathing rapidly, and Karamatsu was still very dazed when his brother let his legs down from his hips, those hands on his ass moving to his waist to steady himself and those teeth on his skin being replaced instead with a tongue, licking at the wound Karamatsu couldn’t be assed to care about right now.
They spent a few minutes like that, holding each other, their scents mixed heavily in the air of the bathroom with the smell of sex and sweat and heat .
Not as much of the last one though, which was good. That was very good.
“... Are you okay?” Ichimatsu suddenly asked, and Karamatsu did his best to blink himself back to reality.
“Y-yeah. Yeah. My legs kind of hurt and my shoulder, but… I think I’m okay. Tired.” He answered truthfully. He heard Ichimatsu hum in response, seemingly preoccupied with something else.
Karamatsu turned his head and looked, just barely being able to see the large, bruising, red bite on his shoulder. “What-- oh, my God !” Karamatsu yelled, sobering up almost immediately as he reached up to pull his hood further out of the way to look at it more. “What did you do ?” He asked, panic seeping into his voice.
He momentarily struggled when Ichimatsu grabbed ahold of his wrist and opposite arm, locking eyes with him before his brother said, “Hey, chill! ”
Karamatsu did. At least, he stopped struggling and instead watched his brother carefully, who seemed a bit surprised at how fast and obedient Karamatsu was being. This alpha thing was definitely something he wasn’t used to. Is this how Osomatsu felt? Whatever, not important.
“Look, just… don’t worry about that for right now. Keep it covered with your hoodie until it goes away. It was… it was an accident.”
“You didn’t say you were going to mark me!”
“I know! ” Ichimatsu barked back, but forced himself to be calm when he felt his brother jolt at his voice. “I… I know . I’ll figure it out, but it’s unimportant right now.The point is, I feel better, so I need you to clean yourself up while I go air out the whole fucking house before the goddamn world knows we… whatever . Understand?”
Karamatsu looked skeptical and unsatisfied with his words, but he nodded, and that’s all Ichimatsu needed right now.
“Good.” He said. “Now hurry up and get new clothes because I need to wash up after you.”
“Will you be okay for the rest of the night? I can still tell you’re not on your suppressants.” Karamatsu spoke up.
“Yeah, we might have to convince Osomatsu a bit, but I shouldn’t be too much a threat to him tonight. I’ll leave early tomorrow morning for the doctor, and that’ll be that, and things can go back to normal.” Ichimatsu said, and noticed Karamatsu’s visible frown. He questioned it silently with a raise of his brow, but Karamatsu shook his head.
Karamatsu wasn’t going to waste time by telling his brother he didn’t like what the drugs did to him and his personality, because really, there was no other option anyway.
“Let’s hurry, then.”
“Don’t steal my words, Shittymatsu.” Was Ichimatsu’s only reply before letting go of his brother and heading out of the bathroom. Karamatsu didn’t fail to notice that the insulting nickname didn’t sound so… insulting this time. His brother’s tone was different.
There was no time to wonder about that kind of stuff right now, though. They had work to do before their brothers got back!
That didn’t stop Karamatsu from having a small smile on his face during his bath, though, feeling oddly… good . Just… good.
It was good.
