Work Text:

After the third hour of endless driving past the same barren, red landscape, Miya Osamu allowed himself a brief respite. This brief respite was from the never-ending chore that had burdened him since birth: Taking care of his idiotic twin brother, Miya Atsumu. Whether that was locating his brother’s lost phone at Haneda Airport, or realising that his brother had taken the wrong luggage from the bustling Melbourne Airport terminal, to simmering a situation wherein Atsumu had accidentally insulted what appeared to be a lovely Australian couple on their most recent flight that seemed to be inbound to the middle of butt-fuck nowhere. No matter where the tides pulled Osamu, Atsumu was surely not far behind, pushing and fighting to get ahead.

It was only now, as their car bumped along the gravelly road, passing red dust and grey shrubbery that repeated for miles ahead, that the younger of the twins let his eyelids flutter. The hours of non-stop travelling had gradually caught up with the boy, his head drooping lazily with each passing moment. Their hire-car was roomy, and large enough that Osamu could stretch out, lounging in the back seat which, after sitting in plane seats for hours, felt like a nest of soft pillows laid by angels. In the front seat he could hear the gentle sound of his mother’s dozing breaths, and his father’s grip on the steering wheel was tight, muscles tensed to keep himself awake on the road. Sleep seemed to be catching up to the entire Miya family.

As Osamu felt the backseat jerk around, he breathed a hefty sigh of annoyance.

Except one.

Osamu peeled an eyelid open to watch Atsumu’s leg jitter uncontrollably. The older twin’s eyes were wide and active, scanning the outside landscape for anything worth seeing as he subconsciously twiddled his fingers together, flexing and stretching them as if silently preparing for a set. The sheer aura of manic energy omitting from the boy was too much for Osamu to handle. With legs heavy like lead, he drags his foot over to lightly nudge his twin’s shin. Atsumu looked at him with sharp, bright eyes.

“Quit it,” Osamu whispered, minding the peaceful aura he wanted to project onto his brother, “You’re makin’ the whole seat shake.”

“Can’t help it,” Atsumu shrugged, ignoring Osamu’s subtle pleas for serenity, “’m bored. It’s borin’ in here. I wanna get out.”

Osamu rolled his eyes. “We’ve still got three hours to go, just put some headphones in and sleep like the rest of us.”

Atsumu scoffed and turned away, shifting his body dramatically to face out of the car window. As the light danced off Atsumu’s profile, Osamu noticed the beads of sweat glistening on his forehead and slowly trickling down his neck, pooling into little stains on his shirt. The air was hot and dry, and being stuck inside the car for hours only made it that much more stifling. In the cramped space the subdued twin could almost smell the stench of his brother. After travelling for hours, no breaks and certainly no showers, Atsumu’s musk was pungent. It smelt deep and masculine, almost like a mixture of an earthy moss smell and salt. It tickled and danced in Osamu’s senses, the smell combined with the slickness of Atsumu’s skin made him almost look good enough to eat.

Osamu coughed, his throat dry as his rationality caught up with his travelling thoughts. He couldn’t remember when he had begun to see his brother in a different light. It wasn’t anything alarming or taboo, at least that’s what he told himself, like a sick mantra. He didn’t love his brother, not romantically at least. He loved him like you love family, nothing more. However, that never stopped his eyes from roaming a bit too freely when changing for practise. It never stopped him from muffling his face in his pillow, ears burning as he listens to Atsumu stifle a moan in the bottom bunk of their shared bedroom, secretly wishing that he could hear that moan in full volume rip from his precious brother’s throat. If he lingered too much on the thoughts they would make him feel sick, so Osamu always forced himself to chalk it up to some sick, egotistical power trip that would be reserved for his youth alone. Unfortunately, as he neared adulthood, when he believed that his mind would finally straighten out, the thoughts only grew with a dangerous ferocity.

Fuck. He’d done it again. He wasn’t about to let Atsumu occupy his daydreaming thoughts. Glancing across at his restless brother, Osamu flipped him off in his mind, cursing the twin internally. Sighing, he ran a hand through his dyed, grey hair. It felt dry and wiry. He paused. Atsumu’s hair always looked so much softer, was it as dry as his own? Sure, they were twins, but did that mean that everything about them was the same? His mind wandered. Shit. He was doing it again, for the second time in less than a minute. Something needed to give.

Sleep. That’s what Osamu needed. He was overtired and irritable, that’s the only reason that his mind was dedicating so much room for his twin, because he was his greatest annoyance. That had to be it. He stretched, feeling his shoulders crack as he hunched them together. With a yawn, he slipped lower into his seat, letting his head drop against his chest as he swung a leg up onto the middle seat between him and Atsumu. Folding his arms in an attempt to get comfortable, Osamu felt his food hit against his twin’s thigh. His eyes narrowed. Atsumu was manspreading, badly. He managed to take up an insubordinate amount of space in the already cramped back seat. If that shithead wasn’t going to rest, it only begs to reason that Osamu should be allowed to push him back. At least, that’s what he told himself.

Osamu jammed his foot into the meat of his brother’s thigh, forcing the blond’s thigh back. Atsumu glared across at his brother, lips pulled into a thin frown as his nose scrunched. Osamu grinned lazily, now having the upper hand. He stretched his leg out along the seat further, pushing his twin along the car seat. Atsumu snarled and slapped his foot, causing Osamu to pull back slightly.

“Oi, shithead-“

“Atsumu,” their father barked, not turning from the steering wheel, “Watch yer language, mister. Also, quieten down, your mother’s sleepin’."Atsumu huffed childishly, arms crossing against his chest, “But ‘Samu’s pushin’ me,”

“Osamu, stop pushin’ yer brother.”

“I wasn’t.”

“Yeah ya were!”

“Oi! Quieten down both of ya. We’re pullin’ over in a few kilometres so ya can take a break then.”

Osamu stuck his tongue out, jeering his brother along while he bathed in victory. Closing his eyes in contentment, he missed the devilish glint that shone in his brother’s eyes. Atsumu never laid down easily for defeat. Osamu had let his guard down.

Feeling a sharp jab in his side, causing him to hiss, Osamu’s eyes shot open. Across from him, bracing himself against the car door for maximum ‘kick strength’, was Atsumu with a shit-eating grin spread across his smug face. The grey haired twin stared daggers at his brother. That was an outright declaration of war. He nudged Atsumu back with his outstretched leg, drilling his heel into his thigh. The older twin gritted his teeth and doubled down on his efforts to kick Osamu.

The twins were now essentially in a heated battle of footsies in the back seat of a hire-car. Osamu watched as Atsumu had to bite back a yelp from a particularly pointed toe-jab into his ribs. Nothing would make either of them back down. This was a war to the death. There was nothing on god’s great earth that would allow Osamu to let his brother snatch this victory from him.

That was, until Atsumu’s foot slipped.

Atsumu’s innocent, well-meaning kick to his brother’s stomach was sabotaged by the sweat pooling against every surface of his skin. With enough slippery friction and an unbalanced, jerky movement, the older of the twins slipped unceremoniously, foot completely missing its desired target. In trying to regain his balance, Atsumu hadn’t paid any attention to wherever his foot may have landed.

Osamu could feel the blood rushing from his face as he paled. Grimacing, he could practically feel his blood rush with dazzling speed to his crotch.

It had happened in a blink and a flurry of limbs, but Atsumu’s foot was now resting directly atop Osamu’s cock. He was frozen, eyes wide and mouth parted. Every nerve end was on fire and he could feel his face heating up and his dick throbbing softly, completely betraying him. He couldn’t let Atsumu see him like this. He’d never live it down. He would be teased until the day he dies. Oh, fuck. Atsumu was shifting. With each attempt to straighten himself out, the blond’s foot dug against Osamu’s pants. Fuck. Fuck. Fuck. He could feel the pulse in his dick begin to race as blood rushed the shaft. His eyes fluttered close, abandoning thought as his brother’s foot ground against his building erection as a soft breath slipped past his lips. The foot suddenly stopped moving, and Osamu’s senses flooded back into his brain. He opened his eyes.

Atsumu was completely still, his eyes boring holes into Osamu. His facial expression remained unreadable, much to the younger’s utter dismay. Slowly, Atsumu moved his foot experimentally, the younger twin looking away as a heated mixture of pleasure and disgust bubbled within. Atsumu’s expression wasn’t one of offence, but it wasn’t a happy one either. It was more… curious. His toes wiggling slightly, the blond twin’s face was scrunched up, thinking hard. Osamu shuddered nervously. There was no way that he could read what was going to happen. Atsumu had practise in keeping his facial expressions completely unreadable. It left him fearless as a setter, and a nightmare as a brother. Surely, Atsumu would pull back, notice his brother’s growing erection, and call him a freak. He would either ignore him and never bring the subject in awkward silence, or would bully Osamu relentlessly for it until the day that they died. What he didn’t expect, however, was the glimmer of excitement that arose in his brother’s eye. Unlike in Osamu’s deepest, most secret and primal dreams that he swore were nothing more than fucked up teenage insecurities, it wasn’t a look of arousal. But it was a look that he knew all too well. It was Atsumu realising that he now had a new toy to play with, a new way to torture his brother, a new way to cease his endless boredom at Osamu’s expense.

With an experimental wiggle, Atsumu pressed the pads of his toes down onto Osamu’s bulge, kneading it softly with light pressure. There was no way that the blond missed the way his brother’s breath hitched, his throat tightening with a note of fear and panic. His kneading grew in intensity as Atsumu grew bolder, pushing down on Osamu’s shaft with his big toe. There was nowhere to run as Osamu could feel his shorts growing tighter as his dick rose against his brother’s toes. He shot a deathly glare at Atsumu, his grey eyes blazing with embarrassment and quiet fury. He was trying to intimidate his brother, to let him know through his heated gaze that he wouldn’t be able to get away with this. However, it was futile. Osamu knew that his brother held all of the power right now.

Listening to Osamu’s breath grow more strained and panted only seemed to spur Atsumu on. His questioning prodding turned into long, caressing strokes as he rubbed his foot along the younger’s length, feeling it continue to harden beneath his touch. Osamu bit back a hiss as his brother’s toe began to nudge against his sensitive head. As pleasurable as it felt, he couldn’t help but feel a defeating sadness inside. It was a gross, disgusting sadness. He hated himself for thinking the way that he was, but he couldn’t help it. He couldn’t help but feel his heart sink as in the eyes of his ignorant brother, he knew that this wasn’t anything sexual. This was purely torture to the older, a new, cruel way to annoy Osamu. There was no lust, there were no shared feelings. Osamu was a string and Atsumu was a petulant cat, swatting him back and forth until he was bored.

And Osamu was growing tired of it.

His thoughts were interrupted when he felt another foot gently tuck underneath his balls, letting them gently fall as it rubbed against them. Atsumu’s pace against Osamu’s dick went back to poking as he tested his limits, saw how hard he could press until Osamu threatened to shout, or moan, too loudly. The older looked beyond satisfied. His grin stretched across his face, revealing white, glistening teeth that shone alongside his gleaming eyes. The reality of their situation still seeming to bypass the setter’s ditzy, arrogant head.

With an exceptionally rough rub against his throbbing, teased dick, Osamu forced a cough to cover the rough moan that left his mouth, jolts of pleasure zapping through his veins. Against the warmth pressure of his foot, Atsumu felt a tiny patch of warmth spread. Panic flashed through Osamu’s brain. Shit. Thankfully, he hadn’t come, but that small drip of precum was enough to awaken his twin out of whatever obnoxious, toying daze he had been in. The reality of the situation slammed into Atsumu like a truck, his eyes widening and mouth agape with a look that, for once in his life, Osamu couldn’t read.

Neither of them wanted to be the first one to break their intense, awkward eye contact. Atsumu slowly drew his feet back, his signature, grandeur style of cockiness nowhere to be seen. His shoulders were slumped and his chest was drawn back. He looked smaller. He didn’t look angry, or aroused, or scared, he wore an expression so mixed and confusing it made Osamu’s head spin. His twin wasn’t supposed to look like this. He wasn’t supposed to be unreadable and small. He was large, dominating, in charge. As much as he wanted to feel bad for Atsumu, an indignant defence was burbling in Osamu’s chest, growing with each dangerous thought he fed it.

Atsumu wasn’t the one who had the right to feel small right now.

Atsumu had begun the teasing. Atsumu was the one who had slipped. Atsumu was the one who had moved his foot, cornering his twin. It was always Atsumu. Osamu was expected to bite his tongue and go along with whatever stupid plan his ‘big brother’ came up with. Even when they fought, Osamu was always the one who had to bite the bullet first, apologising before their relationship would be bruised even further by Atsumu’s ego. It felt like a gear had suddenly clunked into place inside Osamu’s head. It was a gear that was always held onto by his twin, dangling just out of his reach. But Atsumu had lost his power. He had dropped the gear and now Osamu was thinking perfectly clearly. Despite the shame and embarrassment that should have been building deep inside his chest, he didn’t feel it. Looking across at his stupid brother, looking so small and cowering, Osamu felt powerful. He felt incredible. The way his twin’s eyes seemed to tremble when gazing into his felt just as good to his dick as Atsumu’s foot had.

Their fervent stare was only broken when the sound of the car’s ignition being turned off interrupted them. Atsumu shifted his entire body away from his brother, leaning against the car door as if desperate to get out. His fingers tapped against the handle impatiently. Osamu sighed, leaning deeper into his car seat, mind still reeling with an avalanche of feelings.

“Alright everyone,” the Miya patriarch announced, stretching in the front seat with a grunt, “Stretch yer legs. This is the only restin’ spot until we get to the accomodation, after this we are back on the road, understand?”

Both boys grunted their understanding, one far more desperate to exit the vehicle than the other. Once the doors were unlocked, Atsumu sprang out of the car, making a beeline for the shabby, tin hut that seemingly passed as a public toilet. Osamu rolled his eyes. Atsumu was always one for overcomplicating situations. He was brash, and would react harshly and far too emotionally, at least in Osamu’s opinion. His brother was pretentious, loud, and never knew when to draw back. He hadn’t even realised how much it had been grating on his own psyche.

“Are ya okay, sweetie?”

A pair of soft, brown eyes greeted his in the overhead rearview mirror. While built stockily like their father, the Miya twins had inherited their soft, sensual eyes from their mother. She blinked at him through the mirror, a light dash of concern tinting her gaze.

“Yeah,” Osamu replied, shrugging, “Just tired, I guess.”

Smiling sympathetically, his mother replied, “It’s only a few more hours, then you’ll have some quiet time.”

Osamu rolled his eyes, managing to sink into his seat further, “I’ll still have to deal with him.”

His mother laughed, it sounded high and sweet, like the sound of a delicate set of china cups clinking together. She turned in her seat, her eyes still hooded from jet lag and an impromptu nap.

“You’ve always done so well with him, yer father and I really don’t thank ya enough.”

Osamu blushed, his ears turning red as he faced away from his mother. “It’s nothin’. Besides, he’s my brother, I have to.”

Reaching back to ruffle his hair, she smiled, “Just make sure ya take time for yerself, okay? Yer wellbeing is just as important as Atsumu’s.”

With the sound of her car door shutting, Osamu was left alone, for the first time in what felt like years. He straightened himself up, pushing his hair back into place. He could feel his gaze being drawn to the public toilets standing at a distance from the car. His mother was right. He deserved just as much as his twin. His wellbeing was important, and he hardly took care of it enough. Even on this trip, he had spent the whole time babysitting his brother, shielding him from sticky situations that he got himself into. At this rate, he would waste the entire trip, and the only stories he would bring home would be tales of Atsumu’s stupidity and how he had to fix it.

There was the other problem. When had Atsumu ever thanked him for the countless times he had saved his ass? Never. There was never so much as a grateful nod between them. Osamu understood that they were brothers. He understood that boys, especially of the teenage variety, often aren’t extremely good at affection, especially when they’re related, but fuck, was it so much to ask for a ‘thank you’ after years of protecting him? Perhaps, Osamu thought, the only reason he found himself staring at Atsumu, longing to desperately to feel the curves and ripples of each of his toned, athletic muscles was because Atsumu himself had been holding out on the affection for years. That had to be it. Osamu gritted his teeth together, feeling the tension rising hotly in his stomach, filling him to the brim. He deserved happiness. He deserved to take things once in a while. He glanced down at his dick, still bulging tightly in his shorts, seemingly refusing to go down after finally being touched by the object of his- no, his dick’s- affection.

He deserved some pleasure every now and then. That was what Osamu told himself as he shut the car door behind him, heading directly to the shoddy, outback toilets.


The outhouse was humble and rickety, made up of sturdy, tin walls attached to a large tank funnelling the small amount of rain it received into a small sink, sitting below a grimy mirror. Glancing down at the handle, Osamu realised that the door didn’t even have a lock. He looked around, catching his parents walking along a winding, scenic path that stretched away from the lookout and into the red landscape. The air was hot, and silent. No cars passed along the road and no wind rustled the bushes surrounding him. It was now or never. Osamu took a deep breath in, and slammed the tin door open.

Atsumu was hunched over the sink, staring absentmindedly into the dusty, squalid mirror. He barely had time to react to the sound of the door being flung open before his face was slammed against the sink counter, sending a shockwave of pain pulsating across his cheek. Osamu noted how soft his brother’s hair felt under his tight grip, as well as how smooth his skin was as he pinned one of his arms behind his broad, muscular back, damp with sweat. Atsumu flailed, putting all of his strength into trying to shove his younger twin off of him, but Atsumu had always been the lean one. Osamu had more strength and weight behind his movements, he always had, and pinning Atsumu to the sink was nothing more than child’s play to him.

“What the fuck, ‘Samu?” Atsumu spat, growling in angry defiance up at his brother. Osamu never did stuff like this, the first punch was always thrown by Atsumu, it was the only way he had a real fighting shot in winning. He had no chance now.

“I bet ya thought that ya were real funny,” Osamu whispered, lowering his head so that his breath brushed passed Atsumu’s ear, “I bet it was so fun for ya to find a new way to fuck with me, wasn’t it?”

“Let go of me, ya ass!” Atsumu snapped, squirming harder in a futile attempt to escape his brother’s grip. Osamu grinned, a rush of adrenaline coursing through his veins as he realised how intoxicating it was to have his whiny, irritating twin pinned underneath his heavy grip. He pushed Atsumu harder into the sink, his brother’s chest bruising against the dirty countertop. The weight of his brother was crushing, and winded Atsumu.

“I’m gonna kill ya! Ya piece of shit-“

Osamu let go of his brother’s arm, only to raise his hand and bring it down on Atsumu’s ass with the all of the strength of a nationally appraised spiker. The blond yelped loudly and suddenly stopped his wriggling, as if the simple action dulled his mind and caused it to come to a complete stop, the gears jammed by this new, unfamiliar action. Osamu’s hand lingered on his brother’s ass, feeling how strong and moulded the muscle was beneath his touch.

“O-Osamu?” Atsumu breathed, barely a whisper in the air as his eyes, still pushed down against the cold sink, began to well with angry, confused tears. In response, Osamu slapped his hand back down against his ass, watching in delight how his brother’s back arched as his body worked through the stinging pain. It was with this second slap that Atsumu started to squirm again, but the strong grip Osamu held on his skull was warning enough to not move around too much, or the damage could be a hell of a lot worse.

“I’m always cleanin’ up after yer mess, ‘Tsumu,” Osamu said, running his hand along his brother’s curved spine, feeling him tremble, “I think it’s time that I get somethin’ in return.”

Gently caressing Atsumu’s ass, Osamu let his fingers curve into the tight waistband of his brother’s track pants, tugging them down quickly and harshly. The panicked adrenaline that shot through Atsumu now gave him the strength to twist his head out of his twin’s grip, stumbling backwards in the small bathroom as he grabbed for the waist of his pants. Osamu turned, breathing calm and controlled. He was going to get what he wanted. It didn’t matter what came in his way. He had spent far too long being nice.

“What the fuck is wrong with ya?” Atsumu shouted, eyes wide and twitching with fear and fury. His hands didn’t manage to grasp the waist of his pants before Osamu slammed his body weight into his brother, arms wrapped tightly around his waist as he wrestled him to the floor. The sudden impact ran through Atsumu’s body, seeing stars in his eyes as pain shot through his head and back from where the sudden impact had occurred. With his own weight pressing his twin down, Osamu straddled himself on Atsumu’s waist, pressing his thick, veined thighs tightly into his brother’s slim waist, keeping him from moving. His hands reached behind him, pulling down the track pants fully as Atsumu struggled more and more to get out of his grip, throwing obscenities that went through one of Osamu’s ears and directly out of the other. Throwing the pants across the room, the younger twin admired the soft bulge pressing against his brother’s underwear. Of course, Osamu had seen his brother naked before. Hell, they used to share baths. However, this felt very different. The feeling of having enough power to force his twin to succumb to him, to force him to strip off his layers and open himself up in ways he never thought he would felt like a drug to Osamu.

“Is this because of the car?” Atsumu asked, face livid and eyes blazing, yet there was a sweet, underlying tone of confusion and, most deliciously, fear that Osamu felt like he could live off of.

“I was just messin’ around. I feel like ya just gave me a fuckin’ concussion, ya don’t need to punish me that badly, Jesus.”

Osamu smiled, bringing his hand to Atsumu’s face who instinctively pulled away with a hiss. “It’s not as much that I’m punishin’ ya,” Osamu said, “rather that I’m finally takin’ what I deserve. If it hurts ya, that’s simply an added bonus.”

Swirling his tongue in his mouth, Osamu collected his saliva and spat onto Atsumu’s face, watching in delight as the older recoiled in disgust. Leaning down, he spread the saliva with his tongue as he licked up his brother’s face, feeling his muscles tense underneath him.

“You’re fucking disgusting,” Atsumu snarled, brows furrowed and teeth bared, trying to look as intimidating as he could while caged in by his twin’s thick, powerful thighs and biceps. Osamu could feel his hands pressing up against his chest, desperately trying to shift his weight. The futile pushing was cute at first, but it was getting old really quickly. Shifting himself, he trailed a hand up to Atsumu’s neck, resting it at the base softly.

“The less ya fight me,” Osamu said, “The less it’ll hurt.”

Pride was Atsumu’s greatest asset, it seemed, as he spat up at Osamu’s face, the glob of saliva barely making it and more splattering back down on the sender. It was almost pitiful that Atsumu thought that he had any chance of getting out of this. There was still a blazing anger in his brown eyes and a challenging sneer etched across his face. Like always, the full reality of the situation still hadn’t weighed on the older boy.

“Fuck ya, ‘Samu.”

A rare smile curled on Osamu’s lips as his grip suddenly tightened harshly around his brother’s neck. The effect was immediate, panic wiped the smugness from Atsumu’s eyes as they bulged from his head, his mouth beginning to gape uselessly as he desperately tried to gulp down more air, saliva pooling in his mouth as his tongue lolled. His cheeks began to turn a flushed red as his veins bulged out of his forehead, aching to pump oxygen back into his twitching body. His flailing hands began scratching at Osamu’s deathly tight grip, but it wasn’t any pain that he couldn’t handle. It was pathetic how little it really took to have his twin sprawled out, panicking on the floor. Osamu sighed, he thought that his brother would have had a little more fight than this.

With his spare hand, Osamu tugged Atsumu’s shirt up and over his chest, marvelling at the mouth-watering sight. His brother’s chest was toned and hard, built up with years of gruelling muscle training and practise. With no more than five, light hairs dotted around, he looked just as naked as when they used to take baths together, before things went wrong, before Osamu’s mind conjured up some fucked up, repressed, angry fantasy about his twin. But, it didn’t matter what was wrong or right now. He was finally getting what he wanted. As Atsumu’s eyes began to roll back, the whites glistening with tears that dribbled down his cheeks, Osamu yanked down his twin’s underwear, licking his lips.

His brother’s dick was ultimately similar to his own. It was what he had been expecting, average size, but with an intimidating girth. Osamu rolled his eyes and scoffed as he saw how neatly trimmed Atsumu’s pubes were, as if a welcome mat for any guest to wipe their feet on. The dick was still soft, of course, he probably hadn’t even realised what Osamu wanted to do to him. If he hadn’t noticed in the past couple of years of sharing a room, stealing glances after showers and in practise rooms, then Osamu was sure that he would hardly notice now. He probably wasn’t even going to notice until Osamu’s dick was snug in his twin’s tight ass.

The intense scratching from Atsumu began to lessen, and Osamu saw his twin’s cheeks turning pale as his eyes fluttered to stay open. He quickly retracted his hand, watching in awe how his brother’s chest began to heave desperately as he tried to get air back into his system. Osamu squeezed his thighs tight against Atsumu’s sides, drawing the attention of the winded, shaking boy. His eyes were bloodshot and looked hazy, blinking rapidly as he tried to focus on his twin’s face. It was only now, with the oxygen returning to his brain that Atsumu could register how bare and vulnerable he was. Osamu had never seen him look so afraid, so small and weak, and it was all because of him. The pure force of that thought sent sparks flying to his dick.

“I told ya,” Osamu whispered, hand brushing Atsumu’s already bruising throat, “you’ve gotta be more careful, or I’ll start lookin’ for excuses to hurt ya more.”

“What the fuck is wrong with ya?” Atsumu stuttered, weightless anger in his snivelling voice. Osamu smirked and, before his twin could regain the strength to fight again, pushed his weight down and slammed his lips into his brother’s.

The kiss was hot and violent, teeth clattering as Osamu forced his tongue past Atsumu’s shocked, stammering lips. The inside of his twin’s mouth was warm and wet, saliva slipping messily between their lips and dripping down their chins greedily. Atsumu did not kiss back, his lips quivered as his eyes remained wide open in shock. He uselessly pushed his hands against his brother’s chest, trying to defy his younger brother. Osamu licked along his brother’s lips and across the backs of his teeth, exploring his entire mouth with his tongue. Despite rejecting the kiss, Atsumu’s lips remained soft and plump, slicked with saliva and hot under the dangerous kiss. Pulling back for air, through clouded, lusty vision, Osamu saw his twin’s face, and the sight was beautiful.

Atsumu’s cheeks were stained with tears as his eyes were pulled wide and bloodshot, shining with terrified confusion. His lips were parted and soft, red from the brutal attack that they received and wet, drool slipping from the corners of his mouth. His face was etched with pure, unadulterated fear, and it was driving Osamu mad.

“W-wha’,” Atsumu stuttered, eyes pooling with more tears, “W-what’s wrong, ’S-samu?”

Osamu laughed, flinging his head back and scrunching his eyes shut tightly. What a fucking idiot. Atsumu was so egocentric and stupid that he still wasn’t grasping the situation. He looked like a scared, pathetic little deer who was left alone with a big, bad, hungry wolf. It was hilarious.

“Why’re ya so scared?” Osamu crooned, stroking his brother’s cheek, “I know that ya think you’re hot shit, so wouldn’t ya think the same about me?”

Atsumu’s eyes managed to widen further as a new understanding dawned on his face. His trembling doubled tenfold as he began to writhe further in his brother’s tight grip, blushing furiously. Watching him struggle, Osamu brought his hand down sharply across his brother’s face, hearing the crack echo in the room. Atsumu’s mouth was open, as if all of his thoughts and protests had been slapped out of him. With his other hand, Osamu gently stroked along his brother’s chest, feeling the powerful muscles ripple beneath his touch. With gentle fingers, he took one of Atsumu’s nipples into his hand, rolling it slightly and tugging it with feather touches. Hearing the soft, airy breath that left Atsumu’s lips in response almost made him cum on the spot. Atsumu cried more.

“No, don’t touch there,” Atsumu said as he winced in his brother’s grip.

“Why?” Osamu said, “Does it make ya feel too much like a girl? Like a useless sex doll?"

Leaning down, Osamu began to pepper light kisses across his brother’s clavicle, stopping to lightly suck the warm skin into his lips, “It makes sense, doesn’t it? In yer mind, the hottest person in the world is ya, right? So wouldn’t that make me the second? I know yer mind, ‘Tsumu. Don’t tell me ya didn’t want this.”

“Fuck ya,” Atsumu sobbed, all the bravado lost, “Just stop it, okay? I promise I won’t tell anyone, but just fuckin’ let me go.”

Osamu breathed across the soft skin, watching in delight as goosebumps appeared. Still playing with Atsumu’s now hard nipple and mouthing at his chest and neck, he glanced down, a devilish grin spreading on his face.

“Oh really? Yer body doesn’t seem to want me to stop.”

Atsumu glanced down and the colour drained from his already pale face, his breath hitched in his throat as he watched his cock pulse as it slowly but surely hardened. In his triumph, Osamu had let his guard down, too entranced by the sickening scene in front of him to keep his wall of defence up. With fresh strength and adrenaline spurred on by his own horror, Atsumu shoved his arms and chest up into Osamu, knocking his twin back and loosening the grasp his thighs held. With scrambled, messy movements, his shirt still over his chest and pants still grazing his knees, Atsumu kicked himself out from underneath his twin. He stumbled to his feet, panting in terror as he looked around, desperately looking for an escape. His sense of balance was off and he felt completely spun around, spinning his head in search for the door.

Osamu coughed dryly, winded from his brother’s attack. Each step of defiance taken by Atsumu had weighed against a lever in Osamu’s head, and that last attack had snapped it. Rage brewed itself inside of him again. Of course, even in a situation like this, Osamu was taking it easy on his precious brother. He wasn’t taking what he wanted, he was still treating Atsumu tenderly, putting his needs above his own like always. It was such an ingrained habit, it felt like it was weeding itself into every aspect of Osamu’s life. Atsumu was a weed that was invading every crevice of Osamu’s being. The least he could do was take back in return something that he wanted. He’d spent far too long being the soft, submissive, docile younger brother.

Atsumu had always been quick on his feet and was a smart thinker, but when driven by muddled panic, he hesitated far too long. When driven by a silent, lifelong realisation that builded into unbridled rage, Osamu was the faster twin by far. Just as Atsumu’s clear head returned, revealing to him the door, Osamu had his arms wrapped around his waist and drove him back into the floor, face first, his head smacking against the hard floor. Pain alighted across his face as his vision blurred, his head throbbing all over. Osamu straddled himself on his brother’s ass, bringing down another harsh smack to the still bare flesh, leaving a strong, red welt against the pale skin. Atsumu cried out, throwing his head back. Wrapping a hand tightly around his brother’s exposed throat, Osamu leaned in, his lips grazing his ear.

“You’ve filled up far too much of my life ‘Tsumu, it’s only fair that I fill ya up a little now too.”

Atsumu choked, whether from fearful disbelief or his brother’s tight grip on his already bruised throat. Pushing Atsumu’s face into the ground, Osamu caressed and squeezed his ass with a firm grip, pulling back to leave another raw, red hand print across the succulent skin, Atsumu whimpered in response.

“P-please ‘Samu,” he cried, “I-i’ll do anythin’ just- what do ya want me to do? I’ll- I’ll stop- anythin’, just- please,” Atsumu could only babble strings of incoherent and desperate pleas for his brother to stop, but the sputtering only spurred Osamu on further, his finger grazing over his brother’s hole which sent the older into panicked overdrive.

“I’ll scream.” Atsumu said.

“No ya won’t,” Osamu sneered, “The only people around are mum and dad, and ya wouldn’t want to tear our family apart anymore than your constant, demandin’ behaviour has already.”

Atsumu sobbed, his breath gasping and stuttering as he tried to breathe through the erratic, heart pounding terror that gripped his body. With a violent push, Osamu forced his dry finger into his brother, soaking in the yelp he gave as his finger was clenched unbearably tight by the ring of firm muscle.

“Fuck ‘Tsumu,” Osamu breathed, “You’re tighter than I expected a whore like ya to be. How many guys have ya let fuck this pretty little hole before, huh?”

No,” Atsumu sniffed, his muscles contracting in his brother’s grip, “n-none, I’m not- I don’t like-“ His words were blended into incoherent crying as Osamu’s face lit up further, warped with a lustful malice.

“You’re a virgin.” Osamu said, “Good. It’ll feel better for me, at least.”

He continued pushing his finger in and out of the hole, wiggling it around to give at least some leeway and stretch to the tight muscles. Each time Atsumu moved too sporadicly, Osamu would slam his palm down against his ass, mesmerised by the way his flesh would ripple from the sharp contact. The inside of Atsumu’s ass was already so incredibly velvety and wet that Osamu was growing very sick of waiting. His brother was strong, he was athletic, he’d be able to take it. He pulled his finger out, Atsumu whining in pain, then wiped the slick that had built up onto his brother’s soft skin. With hasty and eager movements Osamu fisted his own cock, already threatening to spill at the sight of his brother’s fluttering, already abused ass. He lined his slippery tip up against the hole. Well, at least his precum would act as lube.

WIth an extreme, savage thrust of his hips, Osamu forced his dick, achingly hard and dripping, into the warm, unprepared heat of his brother’s ass. Atsumu screamed, loud and hoarse, as tears sprung from his eyes and he felt his entire body being split in half. It looked like utter agony. Osamu moaned, holding his twin tightly as he felt the fleshy warmth of his own brother’s ass cling to his dick. His ass was red raw, and the younger could now see a fresh trickle of blood running from his torn, violated skin. Swiping it up with a finger, he leaned closer into his twin’s face, which was still covered in tears, drool, and snot.

“See ‘Tsumu,” Osamu grinned, planting a wet, open-mouthed kiss to the side of his face, “You’ve got nothin’ to complain about, at least there’s some sort of lube there.”

Osamu only laughed as he relished in the choked gasps of agony from Atsumu. The older twin had ceased his desperate wriggling, now trembling beneath Osamu’s grasp as his cheeks clenched around the younger’s dick, already threatening to milk it dry.

“F-fuck, you’re tight,” Osamu moaned, slowly moving his dick. It was too dry, and the blood didn’t spread fast enough to make it immediately pleasurable, but the knowledge that his brother, the one person who had ever truly held any power over him, was currently whimpering and weak in his arms, completely vulnerable to anything he may want to do, was enough to nearly push him over the edge. Feeling the blood trickle futher, he began to hasten his thrusting. His arousal built as he watched his brother’s rim stretch awfully to accomodate his girth, puckering and red at the edges as it seemed to suck his entire cock in. He kept a hand on Atsumu’s lower back, pushing it down and forcing his twin to arch up for him, showing him the most of that pretty ass. He landed another slap against the skin, and it hardly seemed to affect Atsumu anymore, already overwhelmed and broken from the constant pain.

“P-please ‘Samu,” Atsumu whined, his hips involuntarily grinding into his brother’s thrusts, “It hurts too much. Pl-please s-stop.” His words were drowned out by the hyperventilating gasps that wracked his body. Osamu continued slowly pressing his dick further in, shuddering with the tight warmth that engulfed him each time he pushed in. Atsumu’s ass was tight, the walls clinging perfectly to the shape of Osamu’s cock, imprinting himself inside of his brother. If he had it his way, no one else would ever touch this ass, let alone use it. Osamu desperately wanted to be the only one to use Atsumu like this, he needed to be the only one to see the teary, ugly expression that graced his brother’s face.

Now feeling confident enough to remove his hands from forcing his twin down, Osamu ran his touch up the sides of his brother’s toned body, feeling the way each muscle dipped and warped beneath his calloused fingers. Atsumu’s build felt far different from his own, despite how similar they may look. Underneath his touch, Atsumu felt hardened and sharp, with muscles that were carved perfectly and none of the stubborn body fat that Osamu couldn’t seem to shake. Atsumu was built lean and strong, he looked like the epitome of an athlete, and yet he melted so delicately under his brother’s touch. Squeezing his hands into his twin’s hips, Osamu sighed as arousal shuddered throughout his core, only sped up by his twin’s pitiful yelps and moans.

Each thrust picked up in speed and the friction made Osamu feel as if he was going to burst, but he knew had to hold out for a little longer. Who knows when he would have the next chance to do this? Not wanting to hold back his moans, he let out a shaky breath as he felt the heat and arousal swell in his stomach, throbbing through his cock eagerly. Each guttural cry and sob from Atsumu sent the same, enticing heat to his dick. Atsumu’s muscles felt limp, like they’d given out, and Osamu had resorted to holding up his brother’s hips with a bruising grip, watching his fingers dig into the soft, delicate flesh. The warmth between their bodies was mind boggling as sweat dripped from one to another, slicking up their bodies as they pressed together, Osamu engulfed in pleasure. He couldn’t see his brother’s dick, it being pressed into the dusty floor, but giving the breathy, bitten back moans that Atsumu was adamantly refusing to let slip past his lips, Osamu could tell that his brother wasn’t hating it as much as his tears and carrying on would have one believe. Atsumu’s body was warm, and his ass now felt delectably soft and wet. Osamu was lucky that the blood wasn’t a turn off for him.

It was with a hard, pointed thrust deep into his twin that Osamu was blessed to hear a loud, gut wrenching moan slip from Atsumu’s lips in ecstasy. Smirking like the devil, Osamu aimed his thrust again, now feeling his dick prod into the sensitive prostate, causing his brother to shake in his grip, breath stuttering.

“It feels good, doesn’t it?” Osamu said rolling his hips in circles to fill every inch of his brother, “I can make ya feel really fuckin’ nice, better than any girl has, right?”

Atsumu only weakly moaned in response, giving his brother full automation of his body and pleasure. Osamu lifted his hips of the ground with a brutal grip on his waist, bottoming out with every thrust at a selfish, alarming speed that left Atsumu a babbling, slobbering mess as his brother’s cock dug against his prostate with each thrust. The younger leaned over his twin and began to press hard, sloppy kisses into Atsumu’s shoulders, biting down hard enough to leave unsightly marks to stifle each moan that rocked his body. Atsumu’s walls clenched so hotly around him, constricting him more with each movement, sucking his dick inside. It was hypnotising to watch.

After finding his brother’s prostate, Osamu made a point to slam into it with every brutal thrust he gave, Atsumu’s wanton moans driving him wild. His speed had found an intense rhythm, the sound of hips meeting ass in an abusing fashion echoing in the small, dingy outhouse. Atsumu’s nails scraped at the dirty floor as each thrust pushed his face further down, smashing his still aching cheek against the ground. With each thrust Osamu watched how his brother’s eyes rolled back further, the way the sweat was dripping off his skin, the way his tongue lolled out of his open mouth, drooling into a pool on the floor. His face looked completely fucked out, blissful yet in absolute agony at the same time. The younger could feel his balls tightening, the sharp coil of heat in the pit of his stomach threatening to snap with each uncaring thrust.

“I’m gonna cum,” Osamu breathed, “ya feel so fucking good, ‘Tsumu,” He brought his hand down sharply on his twin’s ass, watching him keen into the pain of the slap, “This ass is mine, you understand?”

Atsumu vaguely nodded, his eyes clouded over in a horrible, fucked up ecstasy. Osamu reached under, trying to keep his thrusts up to pace as he gripped his brother’s dick, grinning evilly as he felt how hard it was, already slick with precum that he glazed over the tip with his thumb before pulling a brutal pace, matching his thrusts.

“‘Samu,” Atsumu groaned, his hips subconsciously grinding into his twin’s harsh grip, “D-don’t. I don’t wanna- I can’t cum. Please, st-ahh,” His words were cut off by a sharp tug of his hair, Osamu lowering his face again to rest at his brother’s ear, nibbling lightly at the shell.

“I know that ya can cum, ‘Tsumu. Every goddamn night, ya think you’re so sneaky, don’t ya? Mufflin’ yer moans with a pillow, it’s disgustin’. I can hear the slickness of yer dick all the way from my bunk. Do you know what hearin’ that each night does to someone? In reality, ya brought this upon yerself. It’s not that ya can’t cum, it’s that ya don’t wanna admit that the person who’s about to make ya cum the hardest is yer own brother, ya sick freak.”

Osmau felt his brother’s walls quiver around his shaft as his fist was covered in Atsumu’s cum, hot and sticky. Atsumu’s body shook frantically in its release as Osamu removed his grip, focusing all of his attention on chasing the knot of arousal in his stomach. He thrust erratically, ignoring the whimpering from an overly sensitive Atsumu who kept twitching in overstimulated, painful euphoria. His own release followed soon after, with how tightly his brother’s hole was clenching around his hard, throbbing cock. His hips stuttered and his breath hitched in his throat, biting his cheek as his loud moan reverberated in the room as he spilled into Atsumu’s ass, painting his soft walls with his cum. He felt the electricity of his release spasm throughout his body, sending delicious sparks all the way to his fingertips that dusted over the deep bruises already forming on his twin’s hips.

He held himself flush to his brother’s limp body, craving the sweaty, puffed heat that radiated between them. After a few, quiet moments of nothing but hard breathing as both attempt to regain themselves, Osamu gently pulled himself up, slowly guiding his dick out of Atsumu’s ass, watching in complete fascination as his brother’s walls clung to his length, the rim swollen, puffy and sore. His cum, now pink and swirled with drops of blood, began to drip out, splattering obscenely against the ground, slicking up the insides of Atsumu’s thighs, which were trembling still. Osamu stood, wiping his dick clean from the mixture of blood and cum before pulling his shorts up, tucking away his dick. Atsumu was still shaking, but had started to put his weight on his arms, unstably trying to stand. It was a bit pathetic, really.

Osamu walked over, his face having returned to his usual, nonchalant expression and offered a hand to his weakened brother. He wasn’t entirely sure what he was expecting, but it wasn’t for Atsumu to actually take his offer of help, hoisting himself up unsteadily as he used Osamu for balance. What he did expect, however, was the punch to the gut he then received, knocking him back yet only winding him slightly. It didn’t have nearly as much power as Atsumu’s usual punches. Whether that was from physical exhaustion, or some other, secret hope that Osamu dare not give breath to, he would attempt to unravel at a later date.

“Asshole,” Atsumu said, voice carefully devoid of any emotion, “Ya could’ve prepped me better.”

“Ya were the one wrigglin’ around so much,” Osamu jeered, wary of the seemingly casual banter that they had fallen into. Would things really be this easy? He had very much doubted that their dynamic would return to what it was before, so he toed at the waters of their innocent, brotherly teasing with caution.

“I was wrigglin’ because I had no warnin’,” Atsumu said, pulling his tracksuit pants up, wincing with each movement, “Ya should’ve at least given me a heads up.”

“Oh, like ya would’ve said yes and come quietly if I’d told ya?” Osamu laughed dryly, trying not to eye the purpling bruises adorning his brother’s chest as he lowered his shirt, covering his crime.

“I dunno,” Atsumu whispered. Osamu’s head whipped to his face, carefully examining the blush that was spreading over Atsumu’s tear streaked cheeks. His expression was soft and timid, something rarely seen on the older’s face. He avoided eye contact, keeping his brown eyes trained on the ground as Osamu burned holes into him with his gaze, wracking his brain to try and figure out what it all meant. Atsumu’s body language wasn’t closed off and afraid, but it wasn’t as brazen and obnoxious like Osamu was always used to. It was tentative, at best.

Osamu's gaze was one that was full of lust and unbridled passion. It was feisty and hot and Atsumu felt like a complete fool that he had never noticed it before. He had always prided himself as being smart, being good at reading his teammates, and friends, especially his own brother, but in that one moment, he had never felt more stupid in his entire life.

Osamu watched his brother leave, limping aggressively with each step. He maintained his stoic, blank expression as a grin spread across his pounding heart. His mind reeled with graphic and sinful thoughts, sending a humming pulse to his dick, already feeling uncomfortable in his shorts despite having just filled his brother’s ass with a load of cum. Staring into the dry, barren landscape surrounding them, still tired and drained from their hours of travel, Osamu had never been more happy that he would be sharing a small room with his heavenly, stunning, naive brother that night.
