Chapter Text
on the counter was a picture of the happy family- mom, dad, and their son and daughter. it was a beautiful day, one of the only times they were able to convince your brother to get out the house let alone travel somewhere fancy for a change. it was taken outside of the nicest hotel you've ever been in your short little life span. nicest one tomura's ever been to, too. your mother wore a beautiful white dress, clutching your father lovingly around his arm as she held her children with her other arm. your father held you up to be level with your brother, wearing all black and a sour expression during a perfect summer day. you were adorable with your hair tied up in two pigtails, tugging on your big brother's shirt to get him to smile for the picture. you still had missing teeth in that one, they weren't all grown in yet.
the force of tomura shoving you against the wall was enough to knock said picture face down and rattle around the things mom had on her table. your little hands desperately clawed at your brother's wrists, another failed attempt to get him to stop. he forced his hands tighter around your throat with a grunt and making your head bounce against the wall. he was squeezing so tight you couldn't make any noise, only feeling the pressure in your head and neck intensify as the seconds passed by painstakingly.
"you thought hiding in mom and dad's room would work? you're so fuckin' dumb." he grumbled, taking in your pained and paling face writhing underneath him. you got into his stuff and got him caught by dad for 'stealing' some things that he totally didn't even steal. you were a little bitch that everyone thought was a little angel. a little kid can't be all that innocent. you had something inside you that only he saw.
he finally let go, dropping you to the floor gasping for air. he crouched down to your level, making you flinch. he pet your hair, smoothing your bangs out.
"you tell on me, and i'm gonna kill you, got that y/n?" you whimpered, tears rolling down your puffy cheeks. "and i'll know if you say anything to anyone. i'm your big brother and i'm connected to you, so i always know what you're doing."
"t-that's not true!"
"yes it is, you little shit. i know what you tell your stupid bear at night, i'll tell on you right back and you'll be in more trouble than me."
you kicked your feet and sniffled into your shaking hands, you didn't want to get in trouble. you're already in trouble right NOW with tomura, you didn't want to be in trouble with your parents! ever since he got into high school, the things he did to you got worse. it hurt more, it bruised more, made you fear him more. but... he was your brother after all. you would still run to him first when you were in danger- so where do you go when he becomes the danger? your little brain had no clue. time to make him an apology drawing with you two holding hands.
the next day, you were peering into his dark room. his back was turned as he clicked and typed away at his computer, headphones on. the posters on the wall were perfectly lined up- lots of skulls and fire and scribbly writing you couldn't even read yet! it was all very scary, but you had the deep inner urge to be with your brother. he was so... cool. when he played the guitar he was so nice, focused and precise with his movements. you loved to sit on the floor while he showed you a new song he was learning, a lot of messing up and cuss words but you promised not to tell. it was fun to hear him cuss and be cool.
"yeah, my big brother is gonna take me to a concert soon and like it's gonna be so cool." you told your friends at the lunch table at school, all of them gasping and aweing. no one in your grade has ever been to a concert, let alone a super crazy rock concert!!!
"why the fuck would i take you?" tomura scoffed as he threw on his hoodie and stepped into his beat up shoes. your mom gasped, shaking her head and telling him to watch his language around you. heart, instantly shattered. tears bubbling and lip quivering as you threw your stuff to the floor and ran to your room to cry. now what were you supposed to tell your friends?! you cried and cried and cried into your hello kitty pillows, your parents coming into your room before bedtime to comfort you.
"it'll be okay, y/n. your brother is just going through growing up and big brother things. he still loves you, ok?" mom wiped your face off while dad tried to distract you with one of your favorite plushies- one tomura won for you when you two were younger at a fair. you huffed, pulling it under the covers with you.
"why don't you change out of that outfit and go to bed. hopefully tomura will be back soon enough and he'll tell you all about it." dad pat your head from on top of the blanket, mom staying to help you change. a pj set from your favorite cartoon, nice and comfy.
tomura didn't come home until way late. you were stirred awake by some creaking steps and the front door closing. you got up and tiptoed over, peering from your cracked door. it was tomura afterall, trying to sneak over to his room.
"tomu!" you whisper-shouted, and he stopped in his tracks. "it's me silly..." you yawned, pulling open the door further to show him yes, it was in fact you. tomura walked over slowly, chuckling quietly and stepping into your room. you grinned and hugged him, pulling away instantly.
"ugh! you stink!!" you covered your face, stepping away from him and running back to bed when he tried to pull you in again.
"don't be like that y/nnnn..." tomura dragged out your name, he was acting a little weird. he followed you to your bed, peeling off his jacket. he stunk a little less now, but it was still bad. he crawled into your small bed with you, waiting for you to make some room for him under the blanket. he let out a long sigh, hugging you again. ok, he's very weird. he sighed again, humming into your neck.
"stop it tomu, that tickles!" you whimpered, not trying to be loud in fear of waking your parents. it was wayyyy to late for you to be up.
his arms wrapped around you more, pulling you closer. he took another deep sigh, and he laughed as you squirmed around.
"you're so cute and... smell so good, y/n." he mumbled, fingers digging into your flesh. he curled up closer to you, cuddling you, smelling you, holding you. you whined for him to let you go, but he didn't budge.
he ran a hand across your soft pjs. closer. he caressed your head. closer. your eyes fluttered shut, weakly pushing his hands away from touching your smooth belly. "just... let me... y/n..." his voice was low in your ear now, hearing him breathing heavily and feeling the pure heat radiating from his body and feeling his hands clutch your ribs and sides and hips and chest-
"tomu!" you gasped, and he squeezed tighter.
"so flat," he chuckled, fingers poking from the collar of your shirt and tickling your neck. "but that's okay. so cute. fuck, you're so cute. stay still, just like that. let me get comfortable too..."
you felt something against your butt, tomura's fingers wriggling around under your shirt and making you nervous. "tomu-?"
"it's just my belt... i said stay still. you don't wanna wake mom and dad up right?"
you shook your head.
the next morning, tomura didn't acknowledge you at all. he walked right by you and ignored you even when you jumped right in front of him and pulled on his shirt. you were starting to believe you were invisible. while he was on his phone eating breakfast, you decided to surprise prank him. you crawled under the table and tugged on his sweatpants, making him jump. he lifted up the tablecloth and found you underneath, his face completely unamused. you hugged his leg, puppy eyeing him and forcing him to feel bad about ignoring you. he dropped the cloth on your face, groaning.
"i'm gonna kick you in the face if you don't stop bothering me."
"tomuuuuuuu!!!" you whined from under the table, and he scooted back in his seat. you followed, laying your arms in his lap and looking up at him. his face twitched briefly, eyes wide and staring at you. it was scary.
you flinched when his hand came up, but he just held the top of your head.
"nod your head for me, y/n?"
you nodded slowly, confused at his request. your chin rubbed against his pants, cheek resting against his thigh. his hand slid down to hold the other side of your face, squishing your cheek. he smiled.
he smiled!! you grinned. he smiled a little harder, eyes narrowing.
"you look so stupid with that missing tooth." he chuckled, kicking you away roughly. you fell to the hard ground, holding your stomach in pain. tomura stood up and put his plate in the sink, walking out and back to his room with a slam. you whimpered under the table, he was so mean... you didn't believe your parents anymore when they said he loved you. it didn't feel like it at all. you were going to get your big brother to love you!! he would stop hurting you and he would love you like he's supposed to love his sister.
as tomura closed the door to his room, he leaned against it, contemplating. thinking. observing- the tent in his pants after imagining holding his little sister by her hair and forcing her up and down- he slapped his hands over his face and groaned, brushing his fingers through his dark hair.
"hah, i'm so fucked." he shook his head, hearing your little feet make their way down the hall and into the living room. you were probably going to watch tv now, it was the weekend afterall. in those cute little pajamas from the night before. he should've done more, he wanted to know what panties you had on then. he wanted to rip those stupid pants off and just-
tomura slammed his head against the wall, clenching his fists. he could feel the blood in his body all pooling at his dick. his mind was racing with all types of scenarios and possibilities. he knew it was wrong but it's not like anyone could read his mind. as long as he never went all the way, he wasn't doing anything actually wrong.
you were too young to remember anything anyways, probably.
if not, who cares.
he wondered for how long he could get away with it. would you two grow up and it be normal? could he get you to that point?
maybe. you'd probably like it, already a whore for his attention even at this age. god you'd fucking love it, wouldn't you?
and magically his hand was in his pants, whispering the things he would say to you to himself. he imagined all sorts of things he could get you to do. how perfect you'd be. how amazing it would feel. the girls at school were boring or bitches. you, were perfect. made for him. an angel. sent to potentially fuck, conceived only to serve him. god how would any of that even work? a virgin and the ultimate virgin- "...a kid, you're just a kid, y/n..." he whispered, eyes screwed shut. his legs twitched and tensed as he got closer to cumming. he wanted it so bad.
"fuuuuuuuuuck." he groaned, rolling his head back against his desk chair. his breathing was quick, watching the cum pool out and onto his fingers. his brain was working overtime and he just had the best idea.
tomura nearly ran out his room, towering over you on the couch. he had to play this off right. he rubbed his filthy hand all over your cute little face. you gasped and tried to scream but he wiped your lips with it, confusing you enough to not scream. he pulled away finally, grinning at his work.
"tomura!!" you growled, licking your lips. fuck, he could go again right now. he pulled his shirt over his waistband. "what was that!!!"
"my payback for what you did at the table. don't ever sneak up on me again, or i'll put icing on your face while you sleep."
"icing?! this isn't icing!"
"yeah it is, dummy," he laughed. "it's just mom's yucky sugar free kind. don't worry, next time i'll make it really sweet. gonna give all your teeth cavities so they fall out quicker."
"ugh, yuck! don't do that, please tomura!" you pouted, licking your lips one more time and making a face. you were so stupid.
"don't tell me what to do." he pushed you back against the couch with one finger to the forehead. that was risky. but hot.
now time to plan that bedtime visit.
