”You like this, don’t you?”
You let out a wail when your brother fucks into you harder, the sound of his hips hitting your skin making him go faster.
Aizawa swallows, unsure whether or not that Shinsou is talking to his little sister or his father.
“Getting fucked like this in front of your Papa.”
You look up from the pillow to see your father in the doorway, and Shinsou keels over you, “shit, you tightened up, baby. D’you like having his attention on you? Look up at him,” he reaches out his hand to hold you up by the jaw, “already hard and heavy in his pants because of you.”
It’s his first time seeing you together and Aizawa’s barely had any time to adjust and reflect over how your pussy felt wrapped around him, before you’re lying there, tongue lolling out, a string of drool connecting you to the pillow underneath you.
Had it not been for your brother’s hand, your face surely would’ve fallen back down onto the pillow, fucked out of your own mind already.
Aizawa doesn’t realize that he’s palming himself until Shinsou laughs, breathless but confident, “c’mon Papa, has she sucked you off yet? She loves a good pacifier.”
It’s almost mocking, the way that Shinsou calls him papa. Shinsou has always referred to him as anything but fatherly titles, even using Sensei for many years after graduating, but Aizawa can’t deny that it makes his throat constrict in a way that heightens his pulse. With his thumb and middle finger, Shinsou maneuvers your jaw to open your mouth more, and your moans intensify when he pushes into you so hard that you’re falling forward on the bed, soon hanging off of the edge.
Perfect for your father to slide in his fat dick.
He walks forward slowly, unwrapping his binding cloth and unzipping his jumper before he reaches you. You reach out to paw at his thighs, his hips when he comes within range, words left unspoken from the harsh fucking your big brother is subjecting you to. It’s all you can do to catch your breath.
It makes precum dribble out of his aching cock before he releases it from his underwear.
In truth, he’s been thinking about your voice, your grip, your supple skin underneath him all day; there’s been a grueling amount of paperwork from a takedown during his night shift, and it took everything to keep himself together until he could get home.
Shinsou must’ve known, to time it this perfectly.
He lets his underwear fall with the jumper and lets out a deep groan when his hand wraps around his length, directing it to your cheek. He hears his son sigh in the background, mouth hanging open as he looks directly at his father’s hard cock properly for the first time. If Aizawa notices how he starts fucking you more desperately, he doesn’t comment on it.
You immediately stick out your tongue and get drool sloppered all over it, licking from the base all the way to the top in messy, interrupted streaks, bound by Shinsou’s movements. His eyes roll to the back of his head as you suck on his balls, hands coming up to wrap around his length.
You can barely fit a hand around him, and the precum dribbling out of him at the sight has you whining, desperate for a taste of your father’s milk.
“He taste that good?” Shinsou laughs breathlessly when you lick the sensitive head and tighten up around your brother. You hum out a response and Aizawa curses at the way the sound vibrates through his cock, hand going down to caress your cheek. It travels to your hair, running down the length of it before he gathers it in his fist and uses it.
You only have a second to breathe in before your father forces his thick dick all the way down your throat while his head falls back, letting out a groan. Yeah, this is how he should end a long workday every time from now on. There’s an almost euphoric release of tension down his spine at the way your throat constricts around him, gagging and choking while foamy spit dribbles down your chin in thick waves.
“Oooh shit, that’s it, good girl. Take your Papa, show me how much you’ve missed me today.”
Shinsou’s stopped thrusting to look at the way his father forces himself down your small throat, how his Adam’s apple bobs when he swallows, eyes half-lidded and pupils dilated as he watches his daughter spasm at the edge of her bed around his cock. The hairs on Aizawa’s body are standing on end, thick and black, and Shinsou licks his lips as he imagines them soaking wet from your pussy. He imagines you riding Papa’s thigh, the slick wetting the hairs.
His balls ache. He lets out a noisy exhale, oxygen suddenly hard to come by in the small room.
When Aizawa starts to fuck into you slowly, less aggressive as he follows an unheard rhythm, it takes Shinsou only a second to start following it, too, his eyes locked to the back of your head, Aizawa’s hand hidden in your locks as you take both of them. This is so different from when he shared you with a friend, the dynamic entirely tilted in his favor, whereas he feels immediately underneath the sole of his father’s boot, desperate for recognition of his efforts.
There’s a white ring of cum around Shinsou’s cock, your pussy fluttering around him, sucking him in like you never want to be empty ever again. He grits his teeth when you start unraveling in his grip, your whole body convulsing, legs cramping and shaking as Shinsou spreads apart your cheeks to watch your cunt spasm, eyes glazed over as he memorizes the rhythm your pussy ripples in when you cum.
“Shit baby, let go. Yeah, let go for me, such a good girl.” Shinsou hears his father praise you. You’re whimpering, moaning, screaming into his cock and Shinsou knows that Aizawa’s cock is being massaged in much the same way his own is in your pussy.
It’s obscene, wholly unsanctimonious, the suction of your pussy intensifying. He leans over your body now, burying his face in your neck, breathing heavily as he fucks you through your orgasm, adding onto the praise you’re already receiving, good girl rolling off of his tongue while he licks at your nape.
“You’re trying to rip my dick off?” Shinsou laughs when you’re still cumming, still spasming and tightening around him. Aizawa laughs too, a low rumble from deep within him before he pulls his cock out of you. You blanch, tongue sticking out and heaving in oxygen like you’ve been deprived for hours. Every inhale has one word fighting to get out despite the intake of breath. It’s Papa and then it’s Onii-san and there’s absolutely none you say more than the other, one hand reaching behind you, looking for your brother’s hand to entwine your fingers, the other reaching for your father’s.
Both men indulge you, squeezing your hands as they let you come down from your high, watching you with calculated, patient gazes.
Shinsou whines when Aizawa’s free hand, originally nestled and knotted into your hair, suddenly reaches for his, “it’s gotten long, hasn’t it?” he asks curiously. Shinsou lifts an eyebrow and answers flatly, “it’s been this length since graduation.”
Aizawa huffs out a laugh, the conversation so mundane and casual that it makes the situation even more obscene, “I should cut mine soon,” he laments, “it’s getting long again.”
You pull at his hand with a whine, “Nooooooo, Papa, I love your hair so much.”
Shinsou ruts into you, “’s that why you love me? Because I look like Papa?”
It’s a joke, meant to tease you but you immediately sob, “no, Onii-san, I’m sorry, didn’t mean it like that. I love Onii-san for Onii-san, love you.”
It’s clear that being surrounded by both of them is overwhelming you right now, your nerves frazzled and wired. Shinsou kisses at your shoulder apologetically, “’was just teasing baby, I know you love both of us,” he whispers in your ear. You hum and move your hips, trying to make him move again, “love you so much, love you, love you…”
Aizawa clicks his tongue and tuts at you, hand going back to your head, “how many times did he make you cum before I got here, hm? Are you tired?”
You shake your head, still trying to catch your breath, “’not tired, Papa, I promise.”
Shinsou laughs, “she’s been antsy all day waiting for you to come home; had to give her something to do.”
Aizawa smiles down at you as he caresses your cheek, “that so? Couldn’t wait to have a cock stuffed in you?”
Shinsou gets back up on his knees and pulls you with him, your back flush with his front and putting you on display for Aizawa. You tighten around him when Aizawa tuts at you, “you let him bite you like this? Baby…” there’s a scolding to his tone that makes your lash line wet with humiliation as Aizawa lazily lets his palms travel from your hip to your bitten up chest, over your red and blue collarbone and around your neck. Your breath hitches in your throat even if he doesn’t tighten his grip and holds it until he finally continues further to your wet cheeks. Gently, he forces his thumb inside of your mouth and you immediately start sucking on the appendage. Your brother pulls out of you with a groan as he rearranges his own position on the bed, lying down on his back and tapping at your hip to make you situate yourself on his cock again.
Aizawa jerks his head in his son’s direction while dragging his finger over a row of your teeth, “come on baby, weren’t you playing with your brother? You can’t just leave him waiting for you.”
You pull away from your father’s hand to look behind you at your brother, trying to move your legs clumsily so that you’re hovering over him. You try to turn around so that you’re facing him but both men stop you with their hands and their words, “nuh-uh, baby. Back to your Onii-san, sweet girl. Come on, keep looking at Papa.”
You haven’t tried riding your brother while having your back to him, but you trust your family and their directions, so you keep your eyes on Aizawa as Shinsou guides his cock back inside of you. The wet squelching sound of your dripping pussy taking him makes you cringe in embarrassment but it just makes Aizawa smile proudly, “there’s my girl.”
You throb and pulse, the feeling of your brother’s cock and your father’s voice fueling you on. You start rising up and down, riding your brother’s cock, hoping for praise.
You get more than that; Aizawa’s hand travels to your cunt where he immediately puts pressure on your clit with two fingers, circling it and making you arch your back and moan loudly. Your mouth hangs open as you chase the pleasure of hands and cock, the overstimulation forgotten in the pleasure of having both men’s attention.
With your eyes closed and pleasure clouding your mind, you don’t feel or notice Aizawa crawling up onto the bed, your own movement obscuring the movements of the mattress. It’s not until you choke on excess spit that isn’t your own that you open your eyes to see your father above you, spitting into your mouth and smiling at you.
As you cough and splutter and try to catch your breath you tighten around your brother’s cock in a way that makes his hands tighten around your hips, and curse words fall from his lips. Aizawa laughs cruelly, “’s that too much for both of you?” His hand goes from your clit down towards your hole, fingers ghosting over his son’s cock to continue down and squeeze his balls.
Shinsou’s toes curl at the surprise sensation, thrusting into you harshly to alleviate the sudden pleasure heating up his stomach. Your spit mixed with Aizawa’s come out of you in heavy strings, gliding down your father’s forearm and onto the baby blue sheets underneath. Snot mixes with the saliva as you regain control of your throat, a hand going to your own stomach. Desperately, you start riding your brother faster as you look down and watch your father play with his son’s balls. You whine and moan as you think of the pleasure he’s giving Shinsou, feeling so lucky that he also blesses your brother like you want him to. If it feels that good when Papa touches you, it’ll definitely feel good for Onii-san as well, right?
Aizawa’s other hand starts pushing gently at your shoulder, “lie down, babygirl.”
Your brother helps maneuver you down on him and your cheeks heat up at the way you’re put on display like this, cunt throbbing around Shinsou’s cock right in front of someone else, legs spread and exposed. You try to hide your face behind your hands but Shinsou grabs them and keeps them away from yourself.
Aizawa stays on his knees looking down at you as he lazily pumps his cock, pushing out the precum with a heavy sigh, “look at you. Stuffed full and still begging for more.” His free hand starts going up and down your slit and you strain your neck to follow his movements with a moan, your brother patiently calm underneath you, like he knows what’s about to happen. You pulse in anticipation.
You’d wondered when they’d start playing with your ass; so that father and brother could fill you like Onii-san and Denki-nii did, so that you could feel both of their loves at the same time, but none had made the move to do so, and now in this position the hole was essentially closed off. You whimper at the fear that you won’t be able to take them both; you love Papa and Onii-san so much, you don’t want them taking turns.
Aizawa hushes you, his left hand leaving his monster cock to caress your shaking thigh, trying to coax you into relaxing.
Then he slowly pushes a finger inside your pussy; the very same pussy your brother is currently occupying and you throw your head back and wail. With your head against the pillow next to your brother, his breathing is right next to your ear, making you tighten up further. He’s not moaning loudly right now, not groaning either, but there’s a subtle change in his heavy breathing that tells you that he feels good as well; the twitch of his cock inside of you another clue.
They’re both going inside your pussy?
With eyes unfocused you try to look at your father and say something, anything but he’s already shoved in a second finger next to Shinsou’s cock and it hurts- it hurts so much that you unsuccessfully try to close your legs and stop him from stretching you anymore than this. You want to beg him to stop, that you can take him in your ass instead, that it’ll feel better, that it’s more natural, but then his thumb circles your clit and your breath hitches.
“It’s okay baby, it’s supposed to hurt a little, but you’re Papa’s brave girl, right?”
No, you’re not. You’re Papa’s good girl and right now you can’t be good, not when you’re overwhelmed and confused and unsure. Why’s he not just fucking your ass? That’d feel good, that’d be how it’s supposed to be. That’s what you have two holes for, right?
Aizawa chuckles and your eyes widen in fear, but he leans in over you and kisses you, gentle and innocent, “I know it hurts babygirl, I know. But it’ll feel so good, I promise. So good, yeah?” he kisses you in between words and continues massaging your clit. His five o’clock shadow tickles you in a different way than your brother’s, and it’s not until Shinsou starts breathing performatively heavy and in exact intervals that you subconsciously start to follow it and calm down. Aizawa’s fingers still inside of you as well as he gives you a moment to adjust.
“Do you wanna choose between Papa and Onii-san?” Aizawa asks cruelly and you shake your head, no, no no, you want both of them. Next to your ear your brother says, “you love one of us more than the other?”
No no no, no you don’t. You sob as fat tears start running down the sides of your cheeks, wetting your ears, your hair. Aizawa massages your clit again, “then let us both in, yeah? Show us how much you love both of us. Show us how much you want to be family.”
There’s quiet in the room except for Aizawa’s fingers massaging your wet pussy, and it feels like your head’s in a vacuum. Then your beloved Onii-san starts kissing at your jaw, your neck, your ear, “we love you so much baby, so, so much. Love you,” he ruts into you slowly at the final words and you wail, your father using your open mouth to push in his tongue and lick your teeth. Then, before pulling too far away he repeats the sentiment, “Papa loves you, yeah? Wanna be inside here so badly,” he moves his fingers gently, and you stick out your tongue to lick at his lips, his mouth. He lets you as he continues massaging your clit with his thumb. Both men continue to praise you as you start to move your hips of your own accord, realizing that it isn’t so painful or overwhelming anymore. It’s just ache, just stretching. You want to show your Papa and Onii-san how much you love them, too. Show them how much you want to be family.
With a shaky breath you nod and spread your legs wider again to signal that you’re ready. Aizawa kisses you deeply before pulling out his fingers, raising them to your brother’s mouth so that he can lick them clean. The wet sound is right next to your ear, and it’s making you tighten around your brother’s cock, fidgeting anxiously with the hands still in his grip.
Aizawa starts dragging his cock over your pussy, your slit, applying pressure onto your clit, his balls dragging over his son’s. He lets out a satisfied groan, “what spoiled kids I have, huh? Can’t believe my greedy children started fucking each other without their Papa.”
And then Aizawa pushes into your stretched out cunt and your legs immediately start trashing and kicking. The head of his cock’s so much fatter than his meager fingers and it’s so much all at once.
Your brother and your father’s connected inside of you right now and your visions blackens at the realization that they both love you this much. That both of their cocks are rock hard for you, that they want to give you their milk in your pussy at the same time.
Shinsou chokes as all you keep repeating is the word full, but no other words that would indicate complaints. His eyes roll to the back of his head at the drag of his father’s cock against his own; he’d never imagined that fucking his little sister would lead to him being absolutely fucked out by his father, too. He feels his orgasm come dangerously close as his father forces his fat cock into his daughter, making her take it like some sort of fucktoy. His toes curl as you scream out and cum around the two cocks inside of you, thanking them again and again and again and again, your gratitude obscene in the face of the facts. He feels your cum dribble down in hot streaks, and he blearily realizes that Aizawa made you squirt, and it only dizzies him more.
Aizawa grunts and groans into you as he hits your cervix, his balls resting heavily on top of his son’s, finally fully inside of your completely stuffed hole.
“…Holy fuck,” is all he lets out as everyone catches their breath – you especially, with how hard you just came from the penetration – and Aizawa lets a hand travel to the two already connected by his side, pulls at Shinsou’s fingers so that his nails don’t dig deeper into your skin, “that’s it. Papa’s so proud of you,” he says vaguely, referring to both daughter and son underneath him.
Then his other hand travels to your cheek, which you blearily lean against, eyes still unfocused and tongue lolling out, “that wasn’t so hard, was it, baby? My slutty little princess was made to take cocks after all, weren’t you?”
You moan and nod, which only makes Aizawa choke out a breathless laugh, “yeah, you were already fucked silly before I got here but this is something else, isn’t it? Do you like it? Having Onii-san and Papa filling your special pussy?”
Aizawa leans back to take you in, fucked out underneath him. Your legs are twitching as you lie on top of your brother, mind completely fucked out. He leans over your chest and spits, smearing it over your chest, over his son’s teeth marks and bruises, over your nipples and spits again to drag it over your neck, breath shaking and cock pulsing as his large hand encases your throat again; it’d take so little to choke out your breath, to take away your oxygen. You’d look so good with the red marks from his squeezing, too.
But two cocks might be enough as it is, he rationally thinks. He pulls slightly at your hair to get a better view of his son and can’t help the dark chuckle that leaves him at the equally fucked out expression, “you’re about to cum, aren’t you?” he sneers, caressing his son’s cheek gently. A stark contrast to the tone of his voice.
His son, ever the competitor, furrows his brows and start thrusting into your babycunt, trying to school his own expression at the pleasure. Aizawa laughs again and sticks two fingers into his son’s mouth, “y’don’t have to prove yourself to me, I know you’re a slut, too.”
You moan at the drag of both cocks inside of you; every time Shinsou pulls out, your father pushes at your cervix and it’s almost impossible to catch your breath. Your hand goes to your stomach, “so full here, I can feel both of you here,” you moan, leaning your head to the side to look at your brother, your pussy clenching when you watch him suck your father’s fingers.
“You’re close, aren’t you? I wonder how long you’ll last,” Aizawa tells your brother, and you reach out for his face, too, “Onii-san, is Papa making you feel good, too? I love you, Onii-san. Can you give me your milk?”
You’re drooling down onto his jaw, and when Aizawa pulls his fingers out of his son’s mouth, you immediately lean forward to kiss Shinsou before letting him catch his breath, “Onii-san, feels so good, ‘m so full thank you thank you,” you whine into him and you can feel yet another orgasm build up when he kisses back, fucking his tongue into his mouth like he always does.
Shinsou has completely stopped thrusting into you, the stimulation entirely too much. Aizawa’s fucking into you hard enough for the both of them, providing pleasure to both siblings at the same time, and it’s all Shinsou can do to not cum immediately. He knows Aizawa is watching him when he kisses you, praises you, worships you like Aizawa wants him to. Your father would never allow Shinsou to keep fucking you if he did not appreciate you, and his cock throbs as he can feel the calculating stare boring into him as his hands has gone to your chest, to play with your sticky and spit-slicked nipples. You whine and moan and drool, completely lost to the pleasure provided by your loving, adoptive family.
“C’mon Hitoshi, can you cum for Papa? Can you fill up your baby sister?” Aizawa asks and it doesn’t take much more than the throb of your cunt spasming around him for Shinsou to start cumming; he looks into Aizawa’s eyes as he moans and fills you, thrusting and rutting into you in desperate spurts. You quiver, and like a bow being released, you shake on top of him, too, unraveling at the feeling of being fucked full of cum, thanking your Onii-san again and again. The stretch around your pussy makes it hard for any of the cum to dribble out, which only adds to the fullness you’re currently being subjected to.
Shinsou’s orgasm have barely finished before your father starts fucking into you in earnest, putting his whole bodyweight onto you and subsequently Shinsou as well, and lets out sentences that both of you receive with spasms and moans.
“That’s it, yeah, let it all out for Papa.”
“Greedy sluts, desperate for Papa’s cock, yeah?”
“You’re making Papa feel so good, fuck, take it.”
He slams his cock into you so hard that there’re stars in your eyes as you scream, listening to your father as he moans and curses, praising and degrading you at the same time.
He quickly kisses both of you once, before he slams into his daughter’s pussy one last time before thick ropes of cum shoots into your hungry womb. Shinsou’s moaning below, his softening cock overstimulated and sensitive. You take all the milk you’re given like a good girl, your nails scratching at your father’s back. Everything is too painful and every molecule in your body aches when both men pull out, and you barely register that they carry you into another room; barely aware that Aizawa’s wrapping you both in blankets in his bed after cleaning you up. The only feeling you’re aware of is the sensation of burying your head in the crook of your brother’s neck as your father’s warm and secure front wraps itself around your back.
You’ve never felt so safe in your life, nestled between the two men that you love the most. Who loves you the most, too.
There’s a warmth of happiness in your stomach knowing that father and son love each other, too. It makes the feeling of family so much more special to you. You fall asleep with a smile, knowing that you're finally part of a real family.
