atsumu had really outdid himself this time.

the second year highschooler had rudely stomped on a regular's handkerchief despite already having stopped it, almost wiped clean the new umeboshi stock with his gluttoned tongue, and broke osamu's favourite set of crockery.

the crockery was osamu's last straw , for it was very expensive and very rare, and would take six months of savings to replace.

it was not inaccurate to say that osamu was pissed off.

despite being 25 and successful, he had employed his dweeb of a brother as part-time help,

so atsumu could earn some pocket money and he was usually competent. but something must have strung him up to make such ditzy mistakes. he was useless today.

though the whore has its uses sometimes on a good day. helps to relive the ache in osamu's dick which is usually fixed

by a tour to the club.

but osamu is high on discipline and work ethics so very obviously he will teach his younger brother a lesson. in the bedroom.

he waits until it's closing time, delaying it by half an hour more despite having no customers just to spite atsumu further.

"what was that back then in the shop?", he crosses his arms as he looms over a freshly showered atsumu laying on the bed, flippantly scrolling through the gram.

"what? i got off days.", atsumu replied distantly, eyes still glued to his phone. he typed furiously on the tiny keys.

atsumu's lack of attention irked osamu greatly but be witheld his vexation and carefully sat near his brother's foot, the mattress dipping. a sly hand makes it way up atsumu's calves, feeling the strong muscles underneath.

'nah-uh, yer gross, samu, ya didn't take a shower, dirty

!", he snapped back, quite rudely. "not today."

osamu reached his limit of anger and toppled the phone out of atsumu's hands.

"wha-?"

"just cause i've been letting ya run yer mouth, ya go and talk shit to yer older brother?", osamu thunderes, eyes fixed on atsumu's, almost

like a glare. the hand around the slim ankle tightens.

atsumu doesn't back down. "i wouldn't call myself a good older brother if i was constantly looking forward to fuck my younger brother, without a shower, if i may add.", he bares his teeth like a savage, eyes round and

gleaming.

"that's it", osamu growls out and quickly grabs both of atsumu's wrists in a single fist and slides down his sweatpants smoothly with the other.

it happens so quickly that atsumu was dumbstruck, eyes widened like saucers and mouth open in a 'o'.

"let me go, samu!", atsumu writhers like a serpent caught with a stick, body ruffling up the sheets as it tries to escape the strong hold his brother has on him but to no avail.

osamu's strength overpowers his futile attempts.

he ignores the curses that would make their moms

cluth her head falling from atsumu's lips and strikes a slap across his cheek with his free hand.

atsumu stills, eyes watering, a red and throbbing bruise soiling his cheeks.

osamu played volleyball till the end of highschool, was a nationally acclaimed wing spiker,

his slaps hurt like a bitch.

a lesser man might have been driven unconscious but atsumu is toughened by thier brawls.

"samu, what?", atsumu's voice is broken, almost lost in a sob and osamu's dick quickly hardens at his sorry state.

"silence!", osamu strikes another blow to the left side now, so now atsumu has matching red flushes and a tear running down the wound.

"what's this samu, samu thing you keep calling me? i ain't yer twin, I'm yer older brother and you will address me, understood?"

fresh tears join the lone one and even more, till they collect at his lips, and tiny sobs leave atsumu's mouth. he is heaving but he is hard.

"understood?", osamu repeats with a tone that suggests he won't play nice any more.

atsumu nods, broken.

"use yer words."

"yes, sam-, no, ni-san."

"good boy"

osamu ignores the way atsumu easily perkens up at such simple and basic praise and scoots to the edge of the bed.

"now, remove all yer clothes. i want ya naked as the day you were born."

with a moment of hesitation, atsumu slips out of

his school gym shirt, shucking off his boxers too.

osamu could understand why this might have been confusing for the boy. he had always worshipped the ground his brother walked on, treated him as gently as a delicate flower, was always the desperate one in this illict reation.

atsumu had seemed to forget who was the elder here and who demanded more respect.

even now, atsumu was in a state of belief, his nose running as he unsuccessfully tried to rub at his teary eyes.

"bend over my lap, quick!"

atsumu did so and osamu almost came from the sight.

his naked back, clear of any acne and as lithe as a song, stretched alluringly over the expanse of osamu's lap.

his ass was dusted with red, as smooth as a baby's bottom. osamu couldn't wait to turn it purple.

before atsumu could wiggle around in discomfort, atsumu spanked him

the sudden blow almost made atsumu fall off his lap, but his left hand dug painfully into his waist, not letting him do so.

a shrill cry left atsumu's bitten lips, and his nose reddened. it must have hurt. good.

osamu again gave a blow without a second's respite.

quick succesive blows fell on atsumu's ass like rain, gasps and cries and yells and sobs following each.

atsumu kept his head down, wishing to hide his poor state from his brother but osamu roughly grabbed the blond locks and pulled his head back, atsumu protesting with a shriek

.

he was ruined.

eyes red and acrimonious, lips almost torn from his gnawing, the bruises impaled on his cheeks abating yet showing marks and snot dripping down his nose.

he looked beaten up. he looked beautiful.

osamu's pants tightened even more and atsumu must have

noticed it if his eyes didn't lie but osamu didn't react, letting his head fall and striking another spank.

"this one", he gritted out roughly, not missing the way atsumu's own cock was hard as a rock, "for mistreating that poor old grandma"

"she was b-being a b-bitch, ah! no!"

osamu stuck even harder. "quiet, don't talk back." atsumu fell silent.

another hit. "this one for eating all my inventory."

a harsh slap over a purple spot. "this one for forgetting to serve the plums."

atsumu sobbed and sobbed like a broken record. "this one for breaking

my favourite plate!", osamu whipped the palm of his hand over his taint and atsumu /moaned./

"this one for being such a fucking filthy slut who gets aroused from being spanked like a common whore."

osamu angled atsumu's body such that his next hit directly landed on his balls.

white spilled over osamu's work clothes and he cursed.

"ya came.", voice cynical and rough. "and ya are hardening again, what kinda freak-"

"they removed me from the rooster."

osamu's hands stilled in the air, and atsumu turned to meet osamu's eyes, enuciating each word

carefull this time.

"said i wasn't good enough, wanted to keep a first year in my spot, all dirty politics cause i exposed the coach as a pervert who clicks upskirt photos of underage girls. but they said it was a lack of talent purely. that's why my mood was off."

guilt instantly pooled in his stomach and froze like an icicle.

he shouldn't have been so hard on atsumu, pushing down the poor boy when he wasn't ready, beating him up and calling him a slut, shit-

"not to say i didn't like it, nii-san.", atsumu drawled, voice honey,

eyes yet gleaming with tears and osamu understood.

"now let's take care of yer problem, nii-san.", atsumu started to rock his body against osamu's crotch and his older brother steered himself for a long night.

(osamu later raised hell at the principal's office for such an attack against his brother and got the dirty coach fired.)

thanks ghost for the prompt this was a little outside my comfort zone and sorry i couldn't resist making it a bit more my speed with the end and gave atsumu the control. i didn't wanna make him too sad you see😭
