Sakusa doesnāt know if he should be mad or not. The glow of his alarm clock is illuminating his dark room with the soft moonlight slightly peeking in through the blinds. He runs his hands through his curls before he sighs and puts his pillow over his face.Ā
He can hear you. The soft moans and suppressed whimpers coming from plump, swollen lips can be easily heard through your thin walls. If he closes his eyes and really focuses, he could hear how wet your pussy is as you get drilled right next doorāright next to the wall, too, because he knows that you prefer your bed in the corner of the room and the sound of the bed creaking is getting unapologetically louder and louder. He was supposed to be asleep an hour ago for early volleyball practice the next morning, but instead heās listening to you. Every little noise, every creak, every word that slips out of your clenched teeth as you try to be as quiet as you canāāPlease,ā you beg in a broken voice, āY-youāre so big, āTsumu.ā
āTsumu; the little nickname that makes his blood boil and all he can think about is how much of a fucking asshole he is. Yeah, he should be madāhe has every right to be angry, he thinks. Sakusa has to see Atsumu Miyaās cocky face and disgustingly bleached hair at volleyball practice every week and now he has to hear the fucker himself fucking his little sister into oblivion in the next room.Ā
And now itās getting hot in his own room! He scratches the side of his neck in irritation. Why does it feel like his comforters are suffocating him? Sakusa throws his pillow across the room and rips the blankets off of himself. The tip of his hard cock is peeking out from one of the legs of his boxers, almost as if his body is mocking him for feeling this wayāfor getting hard at the sound of his little sister getting split open. He grimaces for a second, but the guilt and shame can hit him later. Right now itās too fucking hot.
So, heās angry because he hates Atsumuāhates how Atsumu has managed to infiltrate his professional life and personal life in such a gross way. Why is Sakusa bitterly pushing his boxers down around his thick thighs? His cock springs free and he grips the shaft harshly.
āFuck,ā Sakusa mutters. He starts slowly, gently pumping his hand around his cock. Itās warm in his hand and twitching at the small bursts of pleasure, enough to allow a pained moan out through gritted teeth. When was the last time he even had someone over to use their body how he pleased? He wishes he could ignore itāignore youābut all he does is pick up his pace as he listens to the sound of your cunt getting destroyed and your sickeningly sweet begging for Atsumu to fuck you harder.
Oh, heās madāso mad that everything is throbbing from his head to the head of his dick. He hisses at the pain in his temples but it does little to stop him from continuing to fist his cock.
āāTsumu!ā he hears you cry out. The sound of your headboard slamming against the wall is getting even louder, accompanied by the slick noises coming from between your legs and skin slapping against skin. The room feels like a sauna at this point, but nonetheless, Sakusa squeezes his eyes shut as he picks up speed and fucks into his own hand like a pervert at the sound of his little sister.Ā
Would you be scared of him if you knew how badly he wanted to be in Atsumuās place? How he wants to rip Atsumu away from you and make you cum on his cock the way he wants to? His skin is getting sticky from his sweatāhis arm is getting tired from how fast heās pumping his cock, desperate to release his frustrations in a stream of hot white liquid and how he wishes he could paint your face with it. He imagines how your lips would feel wrapped around his cockāif you would beg for him through watery eyes and tear-stained puffy cheeks trying to put all of him in your mouth. Is his cock too big for you? Is your pussy as warm and sopping wet as he imagines it is?Ā
āIām gonna cum!ā you scream, āIām cumming! Iām cumming!ā Your voice cracks when you chant for Atsumu. Sakusaās whole body tenses, every single nerve and muscle in his body on fire because damn it, he wants to be the reason why you're screaming and convulsing and crying from pleasure like a whore.
Then with a few more strokes of his cock, he releases his cum in heavy streams that land in a sticky mess on his sheets and lower abs. He groans as his cock twitches against his aching fingers. After a few seconds, he lets go of his shaft and lets it fall against his pelvis. Itās like the whole world has stoppedāthereās no more erotic noise coming from your side of the wall. It would have been completely silent if it werenāt for the sound of labored breaths and giggling. He wonders if Atsumu is going to cuddle you to sleep and stay the night or if heās going to run away and leave you yearning for more.
Embarrassment creeps onto his cheeks with how fast he came, but as fast as the embarrassment comes, the guilt suddenly settles deep into his stomach, into his joints, into every muscle of his being. Sakusa is disgusted with himself for letting his lust take over during a moment of weaknessālust for his imouto who doesnāt know any better, who is in the prime of her life to fuck around and find out without much of a care in the world, who doesnāt think about the consequences. Sakusa canāt do that like you do, itās not built into him except for the few times where he did let looseāalthough heās not as sloppy as you. Sometimes it feels like you were raised in different households. It shouldnāt be a surprise to him that you flirt and fuck with his volleyball teammatesāor anyone that breathes in your direction for that matter. It shouldnātābut for the first time in his life, he asks himself that if you undress for anyoneā¦then why not for him?
He curses to himself. His expectations are too unrealistic. Youāre siblings! And he knows that you both could and should never unless you wanted to ruin your relationship and test your morals. He reaches over to the towel hanging on his desk chair and quickly wipes away the mess he made. A nice, steamy shower pops into his mind, but heās too tired to wash away his sins.
The room gets colder and his transgressions have nowhere to go, marinating into his skin, reminding him that heās a shitty big brother for wanting to ravage you from the inside. As his mind goes hazy from how sleepy he is, he also hears a door open and shut followed by heavy footsteps and another doorāyour door and the front door. A small smirk finds its way across his lips. Sakusa may have a sick attraction to his little sister that he may have recently discovered, but at least heās never lonely. You, howeverā
You can never make them stay long.
~
āOmi-nii~!ā Sakusa hears you sing, bouncing through the hallways of your shared apartment until he feels you wrap your arms around his naked waist. Heās in the kitchen warming up the leftovers you cooked earlier in the day over the stove, looming over the counter and scrolling away at his phone.Ā
He scoffs and leans away from you in mock disgust, āWerenāt you sick last week? Get off me before you give me your disease.āĀ
āI donāt have one! Iām clean!ā you whine with a pout, squeezing your arms around him tighter. You press the front of your body against his back, a gesture that makes Sakusa feel fuzzy, especially when you also press your nose against his bare back to inhale his scent. Thereās something so intimate with the way youāre not even scared to hold him while heās not wearing a shirt. His skin is fresh from the shower and his hair is slightly damp. He pulls away to look at you when he notices how nicely dressed you are.Ā
With a raised brow, he asks, āWhere the hell are you going this late?ā You pull away from him to adjust your dress. He turns to face you, his eyes going up and down your body with sick thoughts beginning to cloud his braināsick, twisted thoughts that should have never crossed his mind.
āFirst of allāā you say, rolling your eyes at him, āāitās not late. Itās literally only six-thirty, you weirdo.ā Sakusa narrows his eyes as he begins to scowl. But despite his obvious look of you better not be going out like that, you happily ignore him. āSecond of all, Iām going out on a date!āĀ
āA date with who?ā he asks sharply, folding his arms against his chest and straightening his posture. He always does this to tower above you, to hopefully make you feel smaller than you are. It worked much better when you were both younger.
You bite your lip before giggling his name, āAtsumu.ā You seem to get bubbly as his name rolls off of your tongue naturally with a smile playing at your lips and warm cheeks to accompany it. Maybe his heart aches a bit with jealousy when you say that stupid name, a feeling that makes the guilt settle heavily again. The last time he heard you say his nameāmoan his nameāwas a few nights ago when he did something no brother should ever do, separated by a few inches of thin walls. As quick as he is to question you, he is also quick to shake those damning thoughts out of his head before they manifest into something more and he ends up losing it in the kitchen you share. Heās scared that he might never forgive himself if he does.
āSince when the hell did you get so close?ā Sakusa shoots you another question with furrowed brows. As monotonous as Sakusa usually is, the distaste is present in his tone and his stance.
āI donāt know,ā you sigh so dreamily, āIt just happened. I didnāt know he could be so sweet.ā He could vomit if he had the chance. Out of all peopleāAtsumu? Really? Sweet?!
āWell, I guess you do have a disease then,ā he retorts, sticking his nose up in disgust, āHeās sick in the head, (Y/N). I thought you had better taste in men but here you go fucking around with my teammateāā
āOmi-nii...ā you pout.
āālike heās the only guy you know. I expected better from you,ā Sakusa continues with a puff of his chest. He turns away from you to turn the stove off. āHeās always sick, too. Always getting a cold and then going to practice like heās not contagious.āĀ
Itās Atsumu taking his little sister away from him that angers him more than he could ever imagineābut itās also knowing that he will never be the one between your thighs that makes him so disappointed. Thereās a silence in the room that creeps up his back.
āYouāve been so out of character recently, Nii-san,ā you ponder behind him, placing your finger on your chin to pretend that youāre thinking, āItās not like you to lose your cool over a guy. Are youā¦
ā¦jealous?ā
No.
Heās just looking out for youāheās your big brother after all! But he doesnāt know how to respond and stands still, holding his breath. Deny, deny, deny. He turns his head to look at you in his peripherals; youāre staring right at him with the same sweet eyes that he remembers from your childhood.Ā Maybe he has been out of characterādid you really notice? As it feels like some kind of tension is suffocating him and the ground is going to swallow him, you crack a wide smile and start giggling uncontrollably, which instantly makes him frown.Ā
This is why you two are complete oppositesāSakusa; as serious as ever and always playing the voice of reason like a good older brother, and you; the first to laugh when itās quiet and always being the fun little sister when things get too serious for your liking. You skip towards him and wrap your arms around him again with the biggest smile on your face, snuggling your nose into the skin of his back.Ā
āYouāll always be my favorite, Omi-nii. I love you more than any boy in the world,ā you hum. He wonders if you can hear his heart beating louder with each syllable of your words.
Sakusa could laugh. Usually he would, before pushing you off and scolding you for getting too close to him. But his heart continues to thump and his voice gets stuck in his throat when your hand slides down his abs and brushes lightly over his twitching cock. Itās not like him to lose his composure like this. You place a saccharine kiss on the curve of his back before you hastily let go of him and walk away.Ā
You didnāt touch him enough for him to say anythingāto reprimand you for touching your Onii-san like thatābut just enough for your touch to linger where it shouldn't.Ā
~
A soft knocking at Sakusaās bedroom door stirs him awake. He groggily twists and turns under his bed sheets, irritated that someone would wake him so late at night. He hears the āclickā of the door knob and the hinges creaking as the door opens.
āOmi-nii?ā you whisper gently from your place at the door. Sakusa ignores you easily, choosing to keep his eyes shut in hopes that maybe youāll leave him alone and let him have his peace.Ā
āOmi-nii,ā you call his name louder and more firmly, āOnii-san, are you awake?āĀ
What a stupid question, he thinks to himself, but Sakusa figures that youāre not going to leave his room any sooner, so he finally opens one of his eyes slowly to see your head peeking into his room. Itās darkāyouāre almost just a black silhouette in his blurry vision, but he can make out your soft and surprisingly tired features just enough. āWhat, (Y/N),ā he groans, his voice gravelly with fatigue.Ā
āCan I sleep with you tonight?ā Your voice is timid when you askāit brings Sakusa back to when you two were younger and you were just as shy to ask him the same questionāand the same question is what prompts him to suddenly sit up, letting his bed sheets fall to expose his lean upper body. He rubs at his eye before looking up to gaze at you, clad in a shirt of his (that he begrudgingly noticed went missing months ago) engulfing your figure.
Omi-niiās shirts are way more comfier than mine, you would whine. He would roll his eyes and snap at you, usually, but would still let you take his shirts anyway. The perverted part of him secretly loves how his clothes fit you.
Sakusa doesnāt ask and figures that itās best that he doesnāt. He sees the way youāre twiddling with the bottom of his shirt between shaky fingers. He could tell you that he was right all along, laugh in your face, anything to rub it ināinstead, he pulls the covers aside and scoots over, creating an empty space for you, just for you.
āCome here,ā he mutters, loud enough for you to hear. You move instantly, your feet delicately pitter pattering against his hardwood floors. The mattress dips lightly as you climb into his bed. You pull his blanket up to your chin instantly and Sakusa grabs whatever he can get. āGo to sleep, (Y/N).ā Without another word, he turns away from you and settles into his sleeping position on his side.
After a few moments of silence, you mumble something Sakusa canāt quite make out. And when he chooses not to respond, you say it again, āCan you hold me, Onii-san?ā Then his body completely stiffens in response. He always said yes when you two were kidsāhell, even when you were teenagers and it was definitely considered inappropriate by then. Would it be weird if he said no now?
But he sighs, knowing that he can't just say no. He turns around and drags himself closer to you, lifting his arm so that you can move underneath it and press yourself into the front of his body. His breath hitches as you do, an all too familiar heat igniting in his stomach as the curves of your body fit perfectly against him.
When he wraps his arm around you, he suddenly feels so complete and so awful, almost having to hold back on how tightly he wants to really hold you. This time he can inhale the scent of your hairāa mixture of whatever shampoo and conditioner you keep in your rotation and your favorite leave-in conditioner. The skin on your arms is soft from your lotion, your legs are smooth and buttery against him, and fuck are you so warm. He could absolutely eat you up right here if youād let him. Maybe in your vulnerable state of mindā¦you wouldnāt say no.
Sauksa doesnāt know what demon has decided to possess him. Heās been thinking too much for the past few weeks for sure. A little earworm is corrupting him, whispering in his ear and daring him to do something and destroy you.
His hands are moving on their own. They slip underneath your shirtāhot fingertips caressing your skin so carelessly and trailing up and down your hips. He wants to laugh because youāre only wearing panties. How obvious can you get? If you were thinking about him the same way he thought about you, you could have just said something.
You tense up at his unexpected touch, but donāt move away from himāyou donāt even say a word, not when his hand slides up to cup one of your tits to pull you closer to him, not when he decides to press his hard cock against your ass, not a single word.
Sakusa thinks heās been too hard on himself recently, especially with how his feelings about you have changed so drastically. Youāre not ready for him like that, that much is obvious with how much youāre shivering, but he deserves this after all the mental anguish you put him through because of how stupid you are.
First, you fuck his dumb teammate in the apartment that Sakusa pays for. And out of all the teammates, you choose the one who used to have piss blond hair back in high school and still slurs his words. Second, you have the audacity to touch him and kiss him and tease him, knowing that he can never have you the way that he wants. Third, you wake him up in the middle of the night to sleep in his bed in one of the shirts heās been looking for for months and just your thin panties that leave so little to the imaginationā
āOmi?ā you quavered, knocking him out of his thoughts. Oh, he didnāt realize how hard he was squeezing you or how rough his grip is on your perky tits. He also didnāt realize how he started grinding himself against your ass, wedging his covered cock between your covered asscheeks in an attempt to feel the warmth from your core. The guilt should have been settling in him again, yet to his surprise, he feelsā¦nothing. All he wants is to hold you down against the bed and wreck your insides until you bleed and beg for him.Ā
āOmi-nii!ā A panicked gasp escapes you and suddenly Sakusa is on top of you, holding you down by your wrists. You gaze up at him, lips parted in shock, eyes so wide, and the first thing that goes through his mind is beautiful. He leans down and presses his lips against yours, leaving you so shocked that your entire body freezes.
āHold still,ā he murmurs, and his words flip a switch in your brain. Youāre already fighting against him, desperate to escape from his hold on your wrists and the sins heās planting on your lips and for the first time in your life youāre actually scared of him.Ā
Sakusa grips your wrists even tighter and hisses as you squirm, āI said hold still.āĀ
Then you force yourself to relax with no choice but to let Sakusa explore your mouth. Your hesitation is obvious (of course, it is) and instead of pulling back and knocking sense into himself, heās offendedāout of all the guys you let violate your body, you wonāt let your own brother do the same?Ā
He disconnects from you to grip both your wrists above your head, holding you down easily with one hand. Then his other hand quickly pushes the bottom of your shirt up to your stomach to display your bottom half and grabs the top of your panties. Youāre horrified as Sakusa effortlessly rips your panties off of you and throws the shredded pieces off to the side, exposing you to the cold air and to your brotherās eyes.Ā
Your brotherās eyes. You can feel the bile coming up to your throat at the realization. Your brother is going to do something to you against your will and you canāt do anything to stop him because heās bigger and stronger than you and you live alone together. As you make eye contact with him, itās like you canāt even recognize him. You jerk your body away in a feeble attempt to free yourself, but itās no use.
āStop!ā you cry, ashamed, scared, and so confused, āNii-san, stop!āĀ
He splits your thighs apart with his own muscled thighs and you feel so weak trying to close them again, to hide that part of you that your big brother should never ever see.Ā
But to Sakusa, itās a sight that he wishes he could see over and over again and he has no problem taking his chances if it means that he can have youāheās already gone way too far, past the point of return, and he doesnāt want to care anymore about what consequences his actions might bring. A small smirk appears on his face as he looks down at you, so vulnerable and small underneath him. He doesnāt want to waste timeāhis boxers are already down his thighs and his cock is free. Youāre looking down at his cock with pure fear on your faceāfuck, heās big, so big that youāre dumbfounded that heās even real. But heās also your brother. You literally grew up together and he still takes care of you and you see each other everyday.
You want to look away but you canāt. Although your vision is blurry due to your tears, you can still see him and only him. āThis is why you asked to sleep with your nii-san tonight, right?ā he breathes, looking down at you with a hunger in his eyes that youāve never seen or noticed before. Youāre shaking your head no. Never. You were just sad and needed your big brother to comfort you without asking any questions.
āStop lying to me, (Y/N). You know what youāre doing,ā he scoffs, āIāll take care of you. Just like I always have.ā Then, he grabs the back of your thigh with his free hand to hoist one of your knees up against your chest, exposing you even more than you already are. Before you can even process it, the head of his hard cock is pressing against your entrance so delicately and so carefully but itās terrifying all the same.
A loud gasp escapes you and you attempt to yank yourself away from him again. Tears are fully streaming down your face now, dampening your hair and the sheets. Your chest is tighteningā youāre so scared. You donāt even know what Sakusa is talking about so you're even more puzzled. As far as you know, youāve been the same as youāve always been. āDonāt d-do that,ā you beg with a crack in your voice, āOmi-nii, please.ā
But Sakusa is pleased to hear your broken voiceāirritated that you donāt want him to continue, sure, but pleased nonetheless. Heās always wanted to see you like this underneath him and he finally has you. Your legs spread wide open for him to feast on is something that seemed so unobtainable yet youāre in his bed, exposed and ready.
Please.
He pushes through the tight rings of your pussy until he completely fills you upāthe tip of his cock is fighting its way through plush walls to kiss your cervix and you swear that your world has shattered into a million tiny pieces. A sob breaks free from your throat.
The room is ice cold. Thereās no more air in your lungs as you convulse around him. You can hear your heartbeat thumping in your ears but everything is so silent. Sakusa lets out a breath that he didnāt know he was holding and suddenly everything is okay nowāhe knows that there was no demon possessing him to think about you in such a dirty way because it was really him all along. All his sick fantasies and insatiable desires, dreams of devouring you, and all those sleepless nights imagining what you would look like with his cock so deep inside you that you couldnāt breatheāit was just him, so painfully in love with you even if he canāt have you. And now heās inside of you. Heās actually inside of you.
āFuck,ā he curses in a strained voice, āYouāre so fucking tight, fuck.ā It feels as if your mind and body are attempting to recover from the shock of Sakusa forcing himself inside your cunt but thereās no time for recovery at allāhell, youāre both surprised that he even managed to slide into you as easily as he did.
Then he starts moving, slow and steady to open you up more. The sting of him stretching you is enough to make you let out a few wails between quivering lips. You can physically feel your walls shudder around his length and your nerves are practically screaming, ringing your inner alarms, knowing that this is so fucking wrong.
āGet the fuck off of me!ā you sob, attempting to jerk your wrists away from his one-handed grip. Youāre not even sure when you became so weak, even with adrenaline coursing through your veins. And youāre even more shocked when he lets go of your wrists for a split second only to hold you by the throat firmly.
āYou need to shut the fuck up sometimes,ā Sakusa breathes with a hint of annoyance. Your shaky hands find their way to wrap around his wrist, nails clawing at his skin, hopelessly trying to loosen his grip. His cock is still moving dangerously inside you, filling you up and then leaving you empty with just his tip, only to fill you up again. The slow rhythm of his hips pressing against yours is tormentingāyour skin is crawling with every moment that your hips meet and you wonder if he moved more then would time go by faster?Ā
Labored breaths and wheezes are the only sounds that youāre able to let out with Sakusaās hand on your throat. Thereās fatigue creeping in your bones yet you feel the energy in your veins and it doesnāt make any sense. Nothing makes sense and everything hurts and justāwhy?
āC-Canātā¦breathe,ā you manage to gasp out. As much as you want to stay awake, afraid of what your older brother might do to you if you pass out, you can see your vision starting to blur and your brain beginning to turn into mush. Your hands are loosening their grip around his arm thatās holding you captive. Heās squeezing your throat tighter and tighter.
You just needed someoneāneeded your onii-san to help you during this fucked up time between you and Atsumu. Usually heād be on top of you like this, fucking you until you cry for him and cum all over his cock. Youād moan and drool and begāanything for him to claim you over and over again. Instead of seeing stupid bleached hair and flirty eyes, you see black curls and dispassionate voids gazing at you as youāre about to pass out and itās like he doesnāt even fucking care! You just wanted to feel better and to feel your onii-sanās comfort again and he decides to touch you andā
He presses his forehead against yours all of a sudden, and you can barely hear him when his lips start moving. ā...What?ā you choke out through wheezes.Ā
āIf you want me to let go, you have to let me fuck you as hard as I want,ā he repeats himself firmly. You donāt realize that heās stopped moving inside you, leaving you feeling oddly empty. All you know is that you need to breathe and maybe that desperation is what makes you attempt to nod your head in agreement. A smirk appears on Sakusaās face and before you can even register what's going on, heās straightening up to thrust his cock even deeper into your core and he finally lets go of your throat.Ā
Youāre coughing and sputtering, oddly embarrassed at how much saliva youāre spitting out, and youāre hyper aware that you have him inside you again, deep inside you and painfully stretching you to the point where youāre afraid that heās going to rip you in half. Sakusa grabs the backs of your thighs and presses both your knees against your chest again, leaving his hands there to hold you down once more and to expose your pussy to the cold air. You feel the warmth spread across your cheeks from how embarrassing it is to be on full display and how repulsive it is that itās Sakusa between your legs to ogle at you as much as he pleases. You wonder what changed between you twoāhas he always felt this way? It makes you sick to your stomach to imagine that your brother that you love so dearly and looked up to your whole life wants you and itās diabolical how this is what he wants from you.
And when he starts thrusting harder than before, slamming his cock into you with such a force that your body lurches with his movements, your brain is back to turning into mush and a part of you wishes that you did pass outāat least you wouldnāt have to be conscious to feel everything. You canāt help but let out quiet whimpers and gasps that donāt even sound like you. It hurtsāthe stretch of his thick cock is so unbearable and his hands on your thighs are sure to leave ugly bruises.Ā
āYou feel so good,ā he almost laughs, like he canāt believe this is happening. You are as soft as he imagined, maybe even more, and how easily your pussy starts creaming around him makes his heart skip a beat. When he presses his forehead against yours again, you want to recoil even though you physically canāt. You donāt want to look him in the eyes yet you canāt bring yourself to look away. You donāt even know if you can hate him after this and Sakusa knows thatāhow you love him so much, even if itās not the way that he wants you toā
ābecause you need him.Ā
Itās nauseating how much you still need him. Itās horrifying how your legs are beginning to shake from how deep he is and how heās shoving himself against your cervix unkindly. Most of all, itās disgusting how you can feelāeven hearāthe puddle pooling from your cunt, forcing you to stretch to accommodate his sizeāand maybe in the midst of your hysterical state, maybe Sakusa feels good, too.
You canāt admit thatāyou definitely donāt want toābut for fuckās sake, you know what your body likes and although itās Sakusa punishing you in the worst way possible, you recognize that tightness in your stomachāthe corrupt feeling that makes you scream and cry and beg, that makes your body writhe in desperation to have more. Fuck, itās morally wrong but at the same time, your body loves to feel full and stretched to its limits. Youāre so sad that Atsumu ābroke upā with you (you werenāt really dating in the first place) because Atsumu knew your body so well and his dick was huge. You really shouldnāt be comparing since the thought is so sickening, yet the way Sakusa is splitting you open is differentāso different from Atsumu with no gentleness, no delicacy, just pure lust and a desire to fuck you until you faint and itāsā¦better. It shouldnāt be better, shouldnāt feel as good as it does, but it's better.
When the realization hits you, the shame and embarrassment floods your stomach, tooāhow could you let your own brother fuck you like this and how could you enjoy it? And now youāre angry at yourself, for how Sakusa is making you feel, how your body is reacting, how raw and wet your pussy, how Atsumu blindsided you, how this whole situation is so fucking unfair.
āOmi-nii,ā you whine with a dry throat, reaching up to grab his thick biceps, all tensed up and veiny from gripping your thighs and turning them purple. His muscles are so well-defined that you almost forget that heās your brother and start melting into his skin. The base of his cock is hitting your clit every time your hips meet, sending shocks of pleasure all throughout your core. The walls of your cunt are convulsing around him. It shouldnāt feel good, it really shouldnāt, but the burning sensation on your thighs from having your knees pressed against your chest to expose your cunt and Sakusa carving the shape of his cock into your pussy is the best fucking thing youāve ever felt in all your years of living. As guilty as you feel for wanting more, you start to beg for him, āPlease make me cum, Omi-nii.ā
A smug smile plays on his lips. Your pussy is dripping everywhere, making wet noises every time Sakusa moves, and he thinks heās finally satisfied. Not completely though, because he wants you to squirt on his cock and he wants you to squirt on his cock every night from now on. He deserves it, deserves this, deserves to be the one inside of you and claiming you and pumping you full of cum.
He leans down and captures your lips with his once again, and this time you let him slip his tongue against yours in a messy passionate kiss. When he lets go of one of your thighs to rub at your clit with his thumb and your body tenses up harshly as a result, he sneers at you, āCum all over my cock, you bitch.āĀ
Then your cunt tightens around him and you hate that heās being so mean to you but you cry and scream and dig your nails into his muscles like youāve never came before because you like how mean he is and the only thing you can pathetically moan is Onii-san~!
He doesnāt stop when you cum, chasing his own high to drown your pussy in his sticky seed and hopefully force another climax out of your body to feed his ego, so he wraps his hands around your throat again while youāre delirious and kisses you again and again. āYou can fuck whoever you want,ā he mutters against your plump lips, āThink that you know what love is when you have some other loser inside youāāĀ
Ā āābut this stupid cunt is all mine.ā
