"A seed of hate from the day I was born
My right to vengeance from me has been torn
Hopeless and drugged, my black emotions seethe
Loveless and cold, my hate begins to breed
Black nebula, seething in my brain
Then your fucking world brings me down again
So I'll take my father's gun and I'll walk down to the street
I'll have my vengeance now with everyone I meet"
— Electric Wizard, "We Hate You"
This was fucked up.
This was downright depraved, illegal too.
Shoto knew this. He could feel the dirt etched into his skin each time he thought about you like this, legs spread and eyes wide in pleasure. As much as he knew how disgusting he was, he rationalized his feelings for you as a sick and twisted perception of love, and not pure degeneracy on his end. While he was held captive in the father wound, you were cherished in his cradle. You were loved. He wasn't.
All father saw was a toy.
It's a conundrum he never wished he had— you were never treated the same way as he was, and he's insanely grateful for that, knowing Enji Todoroki would've already been a dead man if he laid his hands on you. It's one thing if he pushes Shoto around, but you—
Oh. His heart wouldn't be able to take that.
You're too adorable and precious for someone to see you as nothing but a toy, and that's one of the reasons why he despises himself so much. It was all just too wrong for him; for him to hold a grudge against his baby sister, while also lusting for her. You're just a child, a mere 8 year old who flutters your lashes at him and gives him big bright puppydog eyes whenever you want your big brother to give you attention. Afterall, he's all you have—mom is gone, dad's busy, and so are Natsuo and Fuyumi.
And the fact he has you all to himself most of the time is intoxicating, making his mind wander to all the filthy little things he could do to you, and you probably wouldn't even fight him off because of how much you trust him. If anything, it would be your fault, or that's what Shoto wants to tell himself, but he knows it's not your fault. It would never be your fault. He's a sick fuck, infatuated with your soft scent and little body. Shoto should know better. He knows better.
He believes he should be in prison. Should get the shit kicked out of him.
Shoto deserves It. Doesn't deserve to be around you at all, and as much as he would love to distance himself from you, you'd be bawling and that'd mean Enji would have you. It's bad enough you're always on his lap, whining for his attention, and daddy dotes on you because you're his angel, being none the wiser of his cruelty. Besides, people would question why he stays away from his sister, from everyone, and they'd know. They know the shame in his eyes, the way they linger on you for perhaps too long.
It's sickening.
Perverse thoughts circle around his brain like vultures, fantasies of pinning you down and getting what he wanted after years and years of desiring you, shove his dick inside your cunt and pound you until you knew your place. Shoto wants to fuck you so bad, feel that underdeveloped cunny spasm around his cock— possessed by the urge to break you in, defile his father's sweet angel.
It's not a secret. The whole entire world knows how much your daddy loves you, rambling about you in the news like you're his muse, and Shoto fucking hates it. They all do, but they know it isn't your fault. You're just a little girl, and Enji sees no reason to pressure you into being his masterpiece. Flaunting you around everywhere, Enji is utterly infatuated with you, and all it does is make Shoto fester more in disgusting shame. Could eat you alive.
You're the apple of daddy's eye, and he gets to have you all to himself because he made you, Shoto's jealous of him the most. You're at daddy's beck and call, running up to him whenever he returns home, and all he can do is watch. All he wants is to have you be his, be the one doting on you like a sweet kItten. It's not like you hate him, you adore him, but it's obvious that you have a favorite.
As much as your big brother loves you, he loathes you because of how fucking pure you are; still so untainted by this cruel world, untainted by father, and blissfully unaware of his sick desires that have you starring in them… He has to protect this innocence, to keep you safe.
He has to keep you safe from himself.
☆
It started as a simple fantasy.
Little girl, baby sister—you're just so trusting, so easy to take advantage of whenever you're not under daddy's constant surveillance. He imagines settling between your legs and tasting your cunt, swallowing your juices. It's the worst fucking thing he can conceptualize, but it only continues. Shoto wants to rape you, plain and simple. There’s no sugarcoating his desires when you’re still just an elementary schooler.
Currently, your brother is in his room with one hand furiously pumping his shaft while the other presses your panties to his nose, intoxicating him with your fresh yet musky scent. The innocence of an 8 year old left him lightheaded, his face drenched in sweat and tears because he's embarrassing himself.
"Aaah... Fuck..." He mumbles, his chin soaked with drool. Any reminder of you makes him feel like an animal in heat, wanting to pin you beneath him and claim you as his own. Shoto is aware that most of this is him being a teenage boy, but that doesn’t mean he can lust after you. “Such a good girl…”
His mind was full of images of your interactions together, remembering how you always giggled and grinned at whatever stupid thing he could say. For a boy as stoic as he was, it seemed to melt when he was in the company of you. Shoto’s face was hot like a blister in the sun as he recalled your habit of forcing his head on your lap and petting him. He guessed it started because he would do the same thing.
To think he stole your underwear—you wouldn’t look at him the same way ever again. Neither would your mother, or your other siblings, he didn't try to think about it that much.
Shoto peels your underwear from his face, air feeling strange to his nostrils after desperately wishing to suffocate from the cotton. "I need to stop..." He isn't sure who he's talking to, he knows it isn't himself; he's unable to. No matter how many times he tries resorting to cutting his wrists and thighs, it just leads him right back here.
The only peace he can come to is knowing that it's better than him actually touching you, but he's too aware of what a sex crime it still is. A sigh of pain leaves him, feeling like he's between a rock and a hard place. He'll deal with the dilemma as long as he doesn't actually lose his mind and put his hands on you.
☆
That night, you're laying in bed while a storm rages outside. Rain pours from the atmosphere, gushing against your window in a rhythm that leaves you anxious. You remembered what Shoto said about him not wanting you to sleep in his room unless it's a dire situation—he knows how terrified you are thundering...
You attempt to wait to see if you can prove something, but you're walking down the hall just a few seconds later until you're stopped, standing in front of your brother's door. Slowly, you push it open so he couldn't immediately shoo you from his room.
Quietly, your feet went onward until you were climbing into his bed. The movements caused his gaze to flicker open, staring right at you without a single thought in his mind. "Sis, what are you doing...?" He muffled, lazily rubbing at his eye.
"I'm sorry, I couldn't sleep." You answer, pressing your lithe weight against his. Thankfully, the room was dark enough so you wouldn't see how flushed his face was. "It's thundering... I was scared."
You don't seem to realize this is for your own good.
☆
"Niichan? Can you help me bathe?"
Shoto felt tongue tied, stammering like an idiot while your innocent eyes sparkled in his gaze, forcing him to swallow back and address you firmly. "Can't you do it on your own?" He asked, knowing you couldn't. Enji insisted on always giving you a bath like the sick fuck he was.
It's almost humorous how different your childhood is from his—Enji couldn't be bothered to glance at him, let alone wash him. That's where money comes in handy, but he was only vaguely aware of all the women that roamed their hands over his prepubescent body. It was practically a lifetime ago.
"No?" You frowned.
Shoto huffed. "Yeah, sure. But you seriously have got to start doing this on your own..." He muttered, knowing you didn't hear it as you led him to the bathroom. He tried his best to not eye your naked little body, but it was hard when it was next to him.
He slid the cloth over your skin, a giggle leaving you when you shudder from the wetness—he ignores the way his cock twitches, hating how utterly ignorant you can be. It isn't the right time.
Shoto is prolonging it by this point.
☆
Shoto was laying uselessly on his bed, breathing in and out like there wasn't anything in the world to worry about. Looks were very deceiving, because internally, he was thinking about all the filthy things he could do with you. He could breed your cunt, fill you up with seed until there was a pool of it between your thighs.
No, no, that was too animalistic. He scolded himself for fantasizing about being rough with your delicate body, decorating it with pretty bruises that would mark you as his. It'd show your father that you truly belonged to him. If he ever put his hands on you (like he ever would...), he'd have to be as soft as possible with you—you were just a little thing.
In another life, you could've been his pretty wife—in another life, you could be around his age and be his sister wife—in this life, he's your outcast of an older brother. Girls notice him because he's handsome, not because he has a great personality. Shoto mumbles and thinks literally—he isn't sure what Deku sees in him.
All his friends would be so disappointed in him, but Shoto feels like he's at a ropes end with lusting after someone he can't have. This was what he's always feared, getting itchy at the thought of the day where he'd finally give up on resisting.
Would it be tonight? Would it be tomorrow? Could it be next year?
He got his answer when he realized Fuyumi wasn't home, which meant he could finally do whatever he wanted to you. Shoto wasn't sure why it happened, but his sanity was crumbling away everytime he ignored how fresh you were. He strolled into your room with only a single thought on his mind.
You were playing with your toys, glancing at the door with a big smile pulled on your lips. "Hi, niichan!" You chirped, so little, he realized—the size difference was enough to leave him lightheaded. He could snap your bones in half if he wasn't careful. "Do you need something?" You just wanted to be useful.
Oh, he'd show you.
Your excitement melts into confusion when he approaches you. "Sis, I'm so sorry." He says, breaking out into sobs. You have absolutely no clue what he’s crying about, so, your eyebrows furrow as your little brain attempts to make sense of what’s happening.
"Niichan, what are you sorry for?" You cock your head, giving him a hesitant expression. You can't help but feel a little scared—you were always eager to help someone out in need, but this was so unlike the boy that raised you.
"For what I'm about to do with you." A sigh escaped him, all too aware of the fact there’s no coming back. Shoto Todoroki came to his breaking point and there’s nothing he can do except double down on his sick desires by allowing them to manifest into reality—he was going to rape you in the same bedroom where he read you bedtime stories.
"Niichan, please," you give him puppydog eyes. The words feel stuck in his throat, but he coughs them out instead of swallowing them.
"Think you can spread your legs for me?" He directed with a smile to comfort you. It was all too sickening, the way your eyes glittered expectantly while parting your legs just because he asked nicely. His heart pumped in his chest, wanting to burst and kill him right there.
Shoto grabbed your conservatively length skirt that his father forced you in, insisting you learn properly. Don't tempt men, he once told you—he never warned you that your brother was one of them. The fabric was abandoned on the floor, your underwear joining a few seconds later. He lowered his head, causing you to gasp.
"...You're gonna put your mouth on it?" Your words were laced with a purity that made him drip with sweat—you were watching him between your legs. He was completely and utterly fucked. He was going to eat your cunny out. This was all your fault.
"Yeah, exactly like that. Aren't you a quick learner?" He teased, wanting to shake you to the core—you were finally aching like how he ached. His tongue darted out, running across your folds and tasting your divine juices. Shoto moaned from how the honey coated his mouth, embedding in so he'd remember your taste for as long as he lived. “Fuck, you taste delicious.” He muttered, his morals coming to terms with his degeneracy. "How's that feel?" He asked, knowing you were ignorant to how this was his first time too.
It's funny, almost—he could have any girl he wanted. The girls that flock around him at school would sacrifice anyone they loved just for him to acknowledge him, but that wasn't enough to satisfy him. Shoto was a sucker for all things rancid and delicate, playing in a swamp of his own destruction just for a thrill.
"S-so good," your tummy flipped with every lick he gives your pussy, circling the muscle around the rosebud. White hot heat waved in your ear, innocence being consumed. "T-Thank you, niichan."
As saccharine as your excess was in his mouth, bitterness ate away at him from the fact that all of this truly wasn't his fault. If his father hadn't lashed out, he could've spend these years treasuring you like a normal brother would instead of cumming over and over again just from a single whiff of you. Any other teenage boy would've ripped you apart. "Your pussy is so pretty, imouto. I can't get enough of it." He inhaled a large whiff, lapping up at your hairless mound to treasure your adorable kitty fully. Shoto wasn't worthy of it no matter if he got on his knees everyday and ate you out.
You couldn't believe how devoted he was; he was worshipping your pussy with his ravenous mouth. Your toes curled, your back arching off the bed while he ate you out like a man starved. “That’s my good little sister,” he panted between sucks. “You’re so obedient for me. I’m thankful that I have such a sweet little girl like you.” He seriously couldn’t ask for anyone better—you were allowing him to mouthrape you.
His fingers disappeared in your tight heat every so often, scissoring and twisting against the spots that made your brain fuzzy. "Oh, oh, niichan," your mouth was soaked with drool, grinding your hips up and down to meet his rhythm. The angle left you hopeless, reducing you to a drowsy little whore for him. "P-please keep doing that."
"You're loving it?" He couldn't believe it, watching how you nodded. The right thing to do was devour your pussy until you were thrashing desperately, his cock drenched in precum from the fact you were on the brink of your very first orgasm.
“Niichan, I— I have to pee!” You exclaimed, ignorant to what climaxing was. It reminded him how young you were—8 years old and a quivering mess from his mouth, increasing his self disgust while also stroking his ego. "P-pleaseee.... That's, oh—"
It was too late, you were gushing all over his lips. Shoto eagerly swallowed your juices, loving how it coated his tongue—he wanted to be poisoned with your nectar forever. A sniffle left you, overstimulated and panting from your orgasm. He was so mesmerized by the way you arched your back, being the easiest little whore for him while he drank. You were sucked down until there was nothing left to suck.
"N-niichan..." You breathlessly said. "What just... happened? Why did that feel so good?" He was ruining you.
"You have to understand, darling. I'm in love with you." Shoto admitted, watching how your eyes gleamed with something he refused to understand. He had fixated on it for too long, and now it was biting him right in the ass. You were almost excited, but the way he looked at you was making you doubt yourself.
"Niichan... you're– you're scaring me...." You utter, encouraging him in some sick way—unable to be snapped out of this trance. "Please...." You were sure what you were begging for, but you just wanted to be hold because your stomach was twisting in a way that made you queasy.
Shoto leaned forward, caressing your cheek to stare directly in your terrified eyes. "This is what you do to me, imouto." He palmed at his erection, taking it out of his pants and revealing his cock to you. "See? You made me want to ruin my life." It was the truth.
You squirmed, trying to get out of his grip, but it was too late. He pinned you down, crushing you with his superior weight until he was fully connected with your hips, allowing him to sink his cock into your tight little pussy. A groan escaped his lips from how snug your insides felt around him.
I'm inside my 8 year old sister, and it feels so good, he thought, watching your tummy bulge from his length. It wasn't like he had a monstrous cock, you were just a little baby when it came to him. Mom didn't even realize you were growing up everytime you visited her—she would be so distraught if she learned about what her son did to her babygirl—oh, he just wanted to disappear from existence.
“Niichan! Niichan! Pull out! It hurts!”
“Shh, you’re making this worse than it has to be. It’s just your niichan’s cock, you can take it,” he rambled, unable to believe how fucking tight you were. It was leagues better than his fist. "You took my tongue." It's a different thing, Shoto cringes from his lame attempt at manipulating you—pathetic, he doesn't even know how to rape a girl properly.
His hips were stagnant for the first few moments to give you the opportunity to adjust to him, although the stretch was still painful. Your pussy grasped his cock deliciously, coating his shaft with your juices like the filthy thing you were. His love was like an animal's—you learned the hard way.
"N-niichaaan, I- I can feel you in my tummy." Your lashes were wet, sniffling from the abuse you didn't realize you were suffering. "You're so big—"
"That's just because you're tiny." He reminded you, gently caressing the bump to watch your face contort in ecstasy, not feeling his hand sliding down and feeling up your butt. He reveled in the silken flesh before pushing a finger into your tight pucker. Your rim stretched around the digit, squealing from the forced penetration. “Wait— Shoto-nii— what are you doinggg? That’s grosss…”
“Don’t worry, it’ll hurt just for a few moments, sis.” Shoto said softly, thrusting his finger in and out of your hole gently. His stomach twisted with flames from how flustered your face was, getting off on the fact you were completely ignorant to his true intentions. He wasn’t sure why he was being so gentle with you, knowing you deserved worse for being the spoiled brat of the family—
Your holes were so hot, so comfortable—you truly were his flesh and blood, because your cunt was perfect for him. He curled his finger in your ass, hearing how breathless you were from the overstimulation shocking your nerves. It was completely beyond any sense of normalcy you've come to know, your dignity melted from the moment he laid his eyes on you. You were born to be his.
“Fuck, fuck— I'm raping my own little sister.” Shoto can’t help but ramble while he's buried deep in your cunt, unable to cope with what he's doing. He's hostage, a slave to the sweat as he continues fucking in and out of your miniature body. He bullied you with his cock, pushing a second finger within your asshole. "I'm raping my sister and she hates it." He wasn't sure if this counted, but it was like an out of body experience—he watched every detail of you while traumatizing you.
“I- I promise I won’t tell, niichan.” You whimper, unsure what you were talking about. As much as you adored your older brother, you were unsure about this—you didn't want him even an inch away from you, so you'd protect every single secret he had. "Pleasee... Just pull out. I won't tell." Your sobs were so sweet.
"I don't care."
You felt weak from every thrust—made sense, he was twice your size. "Niiichaaaan," you pathetically whined, spurting all over his cock—you milked his cock, forcing him to rut harder into you. He wouldn't stop until you knew your place was being his wife. "I'm sorry..."
"There's no need to apologize. You're the most perfect girl in the world for me." He admitted, knowing he'd never love anyone that wasn't you. Shoto couldn't fathom how these feelings bloomed, but he knew he'd be eternally yours, in life and death. God. He hope he'd die, all too aware of the reserved spot in hell for him. It was too late; he had to double down again.
Really, you were just caught in the crossfire of him not being able to cope properly. It wasn't a fate you deserved despite Shoto's instincts demanding it was, but it was too late now. Your flesh had a pattern of bruises from the relentless brutalizing force of his hips, unaware you had your first orgasm to your 16 year old older brother. If only papa were here...
"I love you so much, sweet girl." Your body twitched, urinating on his shaft. Shoto's eyes rolled back, his hips digging into yours with each second, possessed by his instincts to keep rutting until you were completely stuffed with jizz. His hands enclosed around your neck, gently holding your windpipe. "You know I'd never do anything to hurt you on purpose."
"Pleaseeeee—"
"Don't worry." He pulled his hands away, grasping your hips while continuing to pound into you. "This is me being gentle, imouto. You know I could be a lot worse. I could shatter your ribs if I really wanted to." Shoto said like it was the most amazing thing in the world—having a little girl on his strings, raping your underage cunt over and over again.
Your cunny tugged on his shaft, the sound adding to the obscenity. "F-fuck, 'm so goddamn close," Shoto groaned with one eye squeezed shut, digging his teeth into his bottom lip while pounding further into you, his cock pistoning in and out of your wetness like you were a common whore. "Be a good girl and help your big brother cum."
All you could do it was take it—take his overwhelming need to take everything from you. Mercy dissipated the second he flooded his seed into your underage womb, giving his 8 year old sister a creampie. He admired how crosseyed you were once he pulled out, amazed by his sticky seed dripping from your cunt. He wasn't done.
Shoto threw up all over himself from how ashamed of himself he was, distraught from what he had done. "I- I just raped my baby sister." You were staring back at him with puffy eyes—you were crying so hard, his cock throbbed. "Ohhh my God...."
"Niichan," you were barely audible.
"Don't worry, sis. They'll never find you." Shoto mumbled, beginning to bite into your neck. You squealed again and thrashed, trying to escape—blood gushed from the wound he created, lapping up at the wound like how he was eating your pussy earlier.
"Niichan—what—no, no! That hurts! Stop it!"
He couldn't stop, not when his mouth coated your with blood. It’s such a shame you’ll never have a period. The worst thing was that he wasn't saying anything, not even apologizing, and that's when your eyes gleamed in
pure fear once you understood what his hungry look meant. This wasn’t your brother—this was a beast.
Shoto gripped you by your arm and dragged your little body to the bathroom, having a plan of cannibalizing you there. It just made so much sense to him—you couldn't tell anyone what he did to you when you were swallowed in his bowels. He already knew you were delicious and adorable, he couldn’t stop himself from giving you a terrible fate.
A golden life always suffers through a painful death.
”You have to realize, imouto.” It was all he was willing to explain. “I’m hurting you for your own good.” Shoto left your neck alone, going for your arm. He bit into your flesh while getting off on your screams, briefly stopping to worship the wounds he's created. “God, you’re adorable.” Shoto's cock throbbed wildly, aching to be back inside your pussy. He didn’t need to, he realized as he gripped his shaft and aligned it with the injury, shoving himself inside. You trembled from being woundfucked, his fingers squeezing your throat to keep you steady. "Don't squirm. I'll fuck your eye out if you do."
You sniffled and nodded, obeying every order he gave you. This task was impossible, though—you were terrified out of your mind, but you attempted to relax, thinking about the moments where he actually cared for you. It was hard to believe the one torturing you was your older brother.
"This is what you want, sweetie. You don't have to lie to me." Shoto spoke as if he were taking pity on you, continuing to grind into your arm. He returned to your throat, biting until you were limp under him. His teeth tore into your flesh, pulling out of the wound to pull your arm off with the strength of his jaw.
He already had the idea for a better woundpussy.
Your eyes were pinned lifelessly on the carnage, the remains of your arm in his mouth like a dog with a toy. His molars crushed into it, breaking the bones fully before he got up and took careful strides into the kitchen without his mind, not even realizing what he was doing, retrieving a knife and fork before he came back to your room, staring at your corpse with a smile split upon his lips. Shoto stuck the blade into your wrist, cutting perfect slits into your fragile flesh. It was such a shame he couldn't listen to your pained noises any longer, but he settled for the fact you weren't in the position to tell a single soul about what happened.
You're scaring me, big brother, rang in his head like a wedding vow.
The utensils carefully carved into your chest until his sight was full of your heart, his cock throbbing with the knowledge it'd never beat again. He squeezed the muscle in his hand, seeing how crimson his fingers were. He made a mental note of cleaning all this up later, but that wouldn't explain your absence—that was a problem for him later. "Mhmmmm~"
He pushed his upper jaw down, feeling chunks of meat slide between his teeth. The crimson coated his skin like an honor, but the nerves shaking in his gut was all the same—he recognized it as excitement. Your blood was like an ocean around his feet.
He crouched down on your dead body, reaching his hands out to palm your flat little chest. Shoto tweaked your nipples with his fingers, while his other hand disappeared between your thighs to tease your pussy. He knew you would decompose soon, becoming one with the maggots—he gave you that honor.
His hand wrapped around his shaft, cutting into your stomach to reveal a deliciously inviting hole. Shoto inched closer until it was around his cock, being tugged on by all your squishy organs. "This is better than your cunt," the feeling of your abdomen gripping him tightly was enough to make him burst, but he carried on.
His father made him sick, the world made him sick—you were the cure to everything, he didn't even realize he was sobbing himself. You'd never beg or squirm again. You couldn't protest to anything he could do to you.
Shoto withdrew himself from your stomach injury, pushing his weight down until he was lined up with your leaking entrance. With another push, his cock filled you up. It was such a shame he wasn't able to be encouraged by your sweet mewls, but he didn't register the silence.
"God—" Shoto hissed once your pussy enveloped around him for the second time, still not used to how tight you were, but something caught him off guard. She's tighter now that she's dead, he was in hysterics. His cock slid in and out of you, the filthy sound repeating over and over again in the bathroom, continuing to hypnotize him—he'd never come back from this.
"Yess... that's it..." He drove his cock further inside your walls, groaning from how they clamped down on him. Your corpse was nothing more than a sex doll now, giving him the opportunity to jackhammer you relentlessly. The squelching was everything to him, reminding him of how your flesh sounded when he ate it. "Keep taking it, imouto. Fuck, your remains are the perfect fleshlight."
The ashes of his morality had him aware of how sinful the words were, but this was his new normal. His hips bucked back and forth, humping your corpse like a dog in heat. "Yessss...." Shoto panted, unable to stop himself from blowing his load already—adding to the gross mess between your legs. This would take a ong while to clean up.
His head was completely blank when he pulled out of you, getting up on his feet and glancing around the bathroom until he got a glimpse of himself in the mirror, realizing how stained his mouth was. His eyes were full of depraved hunger, his appetite satiated by you. At least you could die happily knowing you satisfied your brother. It's what any good little sister would do. Laughter escaped him. It wasn't funny.
Once he shifted his gaze elsewhere, he finally came to his senses when he laid his eyes on your remains; your chewed off limbs, split open stomach with missing guts, and cum oozing from your 8 year old cunt. Pieces of you were swallowed down in his bowels, anything to make you stay, anything to make you stay.
“Oh my God…” Shoto said in pure disbelief, his eyes pinned to your corpse before he looked at stained hands once more. He killed you. He raped you and ate you, tasting you between his teeth. His tongue ran it across it involuntarily, wishing you to feel you one last time. This is what he was always afraid of, but he was sicker than he thought he was, he gulped and tasted you again. The only thing he could do was to end his own life.
It was the best decision he could ever make.
