stepdad grisha who fucks you nice and slow, gently because you really are just so sweet. the cutest as you muffle your own cries and keep any protests to yourself as he fills you up with his big cock. you shake when he pulls out, trembling as you feel him slide out of your sensitive walls then fuck himself back into you. his leaky cockhead always hits your cervix, and you take his tongue in your mouth so obediently when he quickly presses his lips onto yours to shut you up so your mom doesn’t hear. you moan and whimper as he speeds up, but all your noises get swallowed as he works himself up to a fast grind, keeping his entire length buried inside you as his cockhead bumps your cervix over and over. you cry when he praises you for taking it all— he knows it’s really too big for you, but this is good for you. cumming all over your stepdad’s cock is beneficial to your health— trust him, he’s a doctor. just promise you won’t say a word to carla about this, or he’ll have to stop giving you all these private treatments that feel so good.
stepbro eren who fucks you so meanly, hard and deep, putting you in a chokehold so neither of your parents can hear the way you squeak when he bottoms out. he knows all about grisha’s inspections into your little pussy behind your mom’s back, and it makes him sick. you’re such a little slut, trying to corrupt his dad with your needy little pussy. he’ll punish you good for making his dad turn into a nasty old man who fucks his daughter and betrays his wife. it pisses him off every time you cry and squeak out excuses— saying it’s not your fault, you never asked for it, your stepdad makes you take those “special treatments.” what a fucking liar. anyone can see you’re doing it on purpose, just so addicted to being full of cock. you confirm that belief every time you tighten up and cum around his length, even though his brutal thrusts in and out of you are meant to be punishments. and eren really does try not to cum inside your dirty pussy, but the way it sucks him in makes it impossible not to. part of him really can’t blame his dad for being so weak when it comes to you, but he’d never admit that. just sends you on your way back to your own bed once he’s through with you, feeling satisfied that you’re all cock-drunk and confused, not even knowing which jaeger’s cum you have leaking out of you.
Contains: older stepsister Mikasa, both over 20, stepcest, pillow humping, slight masturbation, mention of use of toys.
A/N: I hope y'all enjoy. This was my first time writing for stepcest which I'm a sucker for, so I hope I did good. I'm excited to write more of these in the future <3
•Stepsis!Mikasa who is always giving you tips on how to flirt with guys.
•"So i just twirl my hair?" "Yeah but dont forget to bite your lip at the same time"
•Stepsis!Mikasa who goes shopping with you to make sure you buy the hottest stuff and the shortest skirts.
•"Mikasa, if i bend over , you'll be able to see my underwear!!" "Hm, you're right, it needs to be shorter so you don't even have to bend over to show it"
•Stepsis!Mikasa who one night came home early and overheard you playing with yourself. She didnt mean to, she was just passing by when she heard the faint moans coming from your room.
•Stepsis!Mikasa who cant get those beautiful sounds out of her head, especially since her bed is so close to the wall that separates your rooms.
•Stepsis!Mikasa who waits up until she hears the faint buzzing sound of your vibrator or your bed shaking from humping your pillow. She tries to stop herself but always ends up sliding a hand under her panties, moaning as if she was there with you.

•Stepsis!Mikasa that makes herself cum at the thought of your face contorted in pleasure, saliva dripping down your chin, tits out in display, begging for her touch.
•Stepsis!Mikasa who one day just decides enough is enough, she needs to taste you. She waits patiently, like every night, for you to start playing with yourself. As soon as she hears the first moan, she gets up and walks to your room, opening the door slowly.
•She takes a mental picture of the sight infront of her, you on top of a pillow, humping it slowly and what she sees you wearing makes her heart flutter. You're wearing a red shirt but it's not just any shirt, it's her shirt. She let you keep it after you asked to borrow it one time, she thought it looked cuter on you and God was she right...
•What you did next is what finally broke her -"Mikasa... Please make me cum..."- you were moaning her name!! begging for her to make you feel good.All this time, you were touching yourself to the thought of your stepsister.
•"Oh i will, sweetheart, but make yourself cum first. I want to see how you've been making yourself cum, maybe i need to show you a thing or two".
•Stepsis!Mikasa who spent all night with you, showing you different ways to make youself cum. Reassuring you that anytime you couldn't make yourself cum, she'd help you even if it takes all night. After all, that's what a good step sister does right?

step brother armin creeping into your room late at night while you sleep. he’s quiet, careful not to make a sound as he stands over you, making sure you’re out cold before he dares to touch you. you’ve already kicked the covers off of yourself in your sleep, which makes his job a little easier. it also reveals your nearly naked body, clad in nothing but a thin white tank top and white lace panties.
“are you awake?” he whispers into the quiet room, and holds his breath as he waits for a response that never comes. he runs his fingertips along your bare thigh, which is again met with nothing. you don’t even move your leg.
he waits a few beats, wondering if he should really go through with this. his cock is already hard and leaky in his pants, not made any better with the sight of you laid out before him, looking so vulnerable.
“fuck, get a grip.” he mutters to himself, annoyed that he’s getting cold feet now that he stands before you. he knows what he’s going to do. what he has to do. it’s been months in the making. he can’t sleep anymore, can’t think about anything other than his cute little sister. it’s torture having to see you every day, having to sleep just across the hall and pretend he doesn’t have to fuck his cock into his fist every night to the thought of you just to relieve some of the tension that’s built up. he’s a full-blown degenerate now, reduced to stealing your panties and rutting his hips into his mattress and inadvertently brushing his cock against your ass when he squeezes past you. he has to pretend it’s an accident when he walks in on you in the shower or stumbles into your room when you’re getting dressed just to catch a glimpse of you naked. you think he’s just ridiculously prone to bad timing, but he’s not sure if he can keep you fooled for much longer.
he moves quickly, nimble fingers pulling your panties down your legs and off of you in record time without you feeling a thing. he leaves them dangling around one of your ankles before crouching onto the bed, sucking in a breath at the sight of your now naked lower half, your pussy on display for him in the moonlit room. if he’s lucky, you touched yourself before going to sleep. that would make it easier for him to hurry up and sink his cock into you, but he can’t take any chances. he has to prep you if he’s going to keep you from waking up.
so he tests the waters, grabbing your thighs in his big hands and separating them more. you don’t stir, not even when your cunt is only inches away from his face and he can’t help but breathe in your scent. you only jolt a little, sighing deeply when he places an open-mouthed kiss to your glistening lips, wasting no time and slotting his tongue into your hole. he freezes there, watching to see if you’ll wake up, but you don’t. you only relax into the feeling of him tonguing your walls as deeply as he can, then softly trailing up to your clit. he nearly moans into you, immediately addicted to the way you taste.
he continues wetly kissing the small bud until you whine a little in your sleep, and he takes the opportunity to insert one long digit into your pussy. you squeeze softly around it, but you’re mostly relaxed as he pumps it into you. he knows you’re a deep sleeper, and he’s gotten away with this much, so he’s not too concerned when he adds another. the most you do is bring an arm up by your head and turn your face to the other side, your hair fanning delicately over your eyes in the process.
he wants to make you cum like this. he can almost convince himself to finger-fuck a nice orgasm into you and leave. he’d be satisfied just with the knowledge that you came around his fingers, and he’d be content jerking himself off to that image for the next few months. but he’s already here, and his cock is already throbbing and leaking against the waistband of his pajamas. he came here with a purpose.
he sits up, gently removing his fingers from your heat and licking them clean. he wants to kiss you, stuff his tongue in your mouth and make you taste yourself, but that would surely wake you. he’ll save that for another time, maybe when your parents aren’t home and there’s no one to come running if you scream.
he moves your thighs again, as slowly and gently as he can. you stir a little, but not enough to wake, breathing deeply as you settle into the new position. it’s not until you’re spread open and he lines himself up that you start to get a little fussy, making soft noises of discomfort when he pushes the first few inches in. his thick, mushroom tip leads the way for the rest of his length, and he knows he probably should have prepped you a little more to take his size. you’re getting huffy, whimpering a little as you take him in.
“it’s alright, baby,” he whispers, sinking more of his cock into you. you whine, protesting the intrusion in your sleep, but you still don’t open your eyes. “it’s just a dream.”
he’s not lying, really. it is a dream — one that he’s had for far too long, always waking from it covered in his own cum and desperately bucking his hips into the remnants of you that linger in his mind. it always felt so real, but now that your tight walls are actually suctioning his cockhead and pulling him into you, he knows that no dream will ever compare to this reality.
it must hurt for you, though. he can tell by the way your eyebrows furrow and your breath quickens. he wonders what you’re seeing and feeling. he wonders if your dream is allowing for this scenario to play out, or if your precious mind is protecting itself from what your big brother is doing to you.
“it’s okay.” he coos, running a soothing hand down your face, moving your hair away so he can really see you. but he sort of wants you to know. he doesn’t want you to wake up, but he at least wants to be part of your dream. he wants you to question yourself in the morning, maybe feel a little uneasy around him at breakfast. why not, right? it’s fun to toy with you, and he’d hate if some nameless, faceless phantom that your psyche conjured up to play the man who’s sinking his cock into you got all the credit.
“your big brother’s taking good care of you.”
there. he planted the seed, biting back a groan when he finally bottoms out inside you. you jolt, but he’s pleased to see you’ve relaxed a little at the comforting mention of your big brother. he thinks you’ve even opened your legs a little wider for him, too, but it’s hard to say if it’s because of him or just a product of your restless movements.
“a-armin?” you ask, and he stills. his heart thumps harder in his chest as he stares down at you, but as far as he can tell, your eyes are still closed. you haven’t shoved or screamed or kicked to get him off of you. you’re talking in your sleep.
his cock throbs as he pulls out a little to fuck himself back into your warm, sopping wet hole. you gasp, stretching and arching your back into it. “mmm, armin.” you moan.
he thinks he’s died and gone to heaven. you think you’re having a wet dream about him. he couldn’t have prayed for a better outcome.
“yeah, it’s me, baby. just stay still, i’ll be finished soon.”
you relax into it at his words, and he thinks he sees your eyes crack open for a split second before you resign to accept it as fantasy. you’re too tired to fight it, and it feels blissful enough to be considered a dream when the fat cockhead inside you ruts into the spongey spot that makes your legs shake. you can see him in your mind, your handsome big brother humping into you desperately. he feels so real, it feels so good. in the back of your head you know it’s wrong, but you can’t control it.
“armin,” you whine, sighing as lips trace down your neck softly. it’s so vivid you can feel the grazing of his teeth against your skin. you’re a little less than half-conscious now, because the jostling of your body gets harder the more your big brother pounds into you. but the pleasure increases, too. you’re close to cumming, but you’re so afraid of losing the dream just before you get to release that you don’t fight it.
“my big, big brother.” you say in sort of a rushed sigh that turns into a high-pitched gasp. your body gives way to tremors as you cum around his cock, and behind closed eyes you see your big brother panting along with you, abs tightening and his bottom lip caught between his teeth. you breathe out another dreamy sigh when a warm feeling fills you up.
armin can’t believe you didn’t wake up when he came inside you, but you rather opted to snuggle deeper into your pillow with a peaceful smile on your face. you think you dreamt of your brother rutting into you and filling you up with hot ropes of cum, and it made you fucking smile. you might just be sicker than he is.
he removed himself carefully, fighting against the death grip your walls had on him as he pulled out. he almost pulls your panties back up to cover your leaking pussy, but decides against it. he still wants you to be a little confused in the morning.
and you are. waking up with a dull throbbing sensation in your pussy is one thing, but leaking cream out of your hole and onto your sheets is another. and where the hell are your panties? you could have sworn you went to bed with them on, but they’re nowhere to be found. it’s bizarre, but you chalk it up to the weird dream you had that left you feeling equally as strange. you probably took them off in your sleep and tossed them aside somewhere, however unlikely it seemed.
it wasn’t until you saw armin in the kitchen after quickly throwing on sweatpants that an odd feeling settled in the pit of your stomach. he was shirtless, plaid pajama pants hanging low on his hips and his hair tussled. a hot flush rose to your cheeks as he greeted you in a raspy morning voice, vivid memories of your dream taking over your mind. armin, you remembered. you had a wet dream about your brother — easily the most intense dream you’ve ever had. you remembered how desperately you wanted it, how good it felt, and cumming so hard in your sleep it practically knocked you out.
“something wrong?” he asked, but you couldn’t find the words to respond. it was humiliating. how could you ever look him in the eye again?
“no. nothing.” you choked out after he raised an eyebrow at you. he fought the urge to smirk. he had you just where he wanted you. he could see you questioning reality, going over your memories of last night in your head as you avoided his gaze.
it really did feel so real. sounded real, too. and the throbbing in your pussy this morning was real. so was the cum, and your missing panties. was it real?
you dared to glance at him while his back was turned, thinking it over. no. no. there was no way. big brothers don’t fuck their little sisters in their sleep— do they? your abused hole clenches around nothing at the thought. you still feel full, with remnants of the mysterious liquid still leaking out of you and making you feel needy all over again. what if it’s armin’s—
you almost drop to your knees as he stands behind you to grab something from the cabinet above you, an unmistakable bulge pressed against your ass. you gasp, but he’s gone before you turn, now walking towards the fridge. you catch sight of him toying with a small piece of fabric sticking out of his pocket — white lace. you feel dizzy. you’re still throbbing, you can still feel the phantom — no, your brother — pounding into your pussy almost as vividly as it felt in your dream. you feel the warm, sticky pool of cum inside you, and you think you’re going to pass out.
“so,” he starts, opening the fridge nonchalantly. “how did you sleep?”

thinking abt step brother reiner who has the fattest cock.
just 7 inches of girth with a pretty pink, leaky tip. your eyes roll back and your legs start to shake before he’s even finished stuffing it in. and he feels so bad when he sees tears gathering in your waterline as you bite your bottom lip to hold in a cry. he’s just too big. you’ve never been stretched like this. you can't do anything except take it, your walls tightening and squeezing around him as you try to adjust.
“fuck,” he grunts, and he’s lightheaded because you’re still squeezing rhythmically around him. he’s got you in your bedroom, held up against the wall with your legs hooked over his strong forearms. he’s so big, he’s got you so far off the floor, towers over you and makes you feel weightless. you’re dizzy as he pushes himself in to the hilt, leaky cockhead pushed right up against your cervix. “s-sorry, don’t cry, we can stop if you want.”
but even he knows that’s a lie. he couldn’t stop now even if he wanted to, even if you begged him to. your tight clutch has a death grip on him, it’s so warm, feels so good. and he’s been dreaming about this for as long as he can remember, no matter how much he denied it up to this point.
“no, no, don’t stop.” you whine, your hands tangling through his hair. he leans into your touch, his lips ghosting over yours, breathing in your scent. it’s wrong, it’s so wrong, but you've been begging for it for so long. you tempted and teased and tortured him for it, with soft kisses and lingering touches, flaunting your ass in front of him, touching yourself to the thought of him, moaning and whining his name through the thin wall that separates your rooms. it was agony.
“i love it— love you, love you so much.”
god, he knows. he knows you love him. he loves you, too, more than anything. definitely more than a big brother should love his little sister, but he can’t think about that right now.
he holds you tighter, his grip bruising as he pulls back and delivers another thrust that makes you cry. he knew you couldn’t take it, he tried telling you, but you got so cockhungry and stupid at the sight of his hard bulge through his sweatpants that his warnings meant nothing. so wet you left a damp spot where you humped him through your thin cotton panties like you were in heat, mewling and crying and promising it would just be this once, never again, just so he can relieve the emptiness. whining that you just can’t cum on your own— not that he needed you to tell him that. he’s heard you, crying late at night because your fingers just can’t get the job done. he’s fought the urge to creep into your room to help you so many times, instead fucking his cock into his fist at the sound of your broken moans and whimpers of his name. but he was in the same predicament. it just wasn’t enough, unsatisfying because it wasn’t you.
"i love you, too." he groans, pressing his forehead down to yours as he drives his hips forward again. you're impossibly tight, he knows it has to hurt. "you're taking me so well. just breathe."
you nod, gasping and choking because each thrust knocks the air out of you. you're hanging onto him for dear life, and although the stretch burns and your cervix aches, you're so happy taking his cock deep inside you. it's all you've ever wanted. you almost flutter your eyes closed each time he bottoms out inside you, but he looks so pretty you can’t help but stare. large muscles taught and sweat glistening on his skin, with small beads running down his temples. his eyebrows furrowed, his lips open as he stutters out groans and curses. you tighten up again, squeezing around his thick cock because you want him to feel good. he gasps, his body jerking forward to pin you more firmly to the wall. you take the opportunity to pull him down a little closer, pushing your open lips onto his and tangling your tongues together.
reiner never really lets you kiss him like this. it makes him too hard, weakens his resolve too much, so you take full advantage while you can. you moan into it, greedy for more, sucking his tongue while he forces himself into your tight heat over and over. you want his cock in your mouth next, you wanna go stupid and choke on it and swallow his cum. you can’t believe he’s never let you, but after this, you know he’s likely to give you just about anything you want. you know he feels bad now, but he’ll feel terrible in the aftermath, when you really milk the situation for everything it’s worth— tears and leftover bruises from his strong hands, and your puffy, swollen pussy that’s just been pounded to hell and back. you’ll hold it over his head for the rest of your lives, that he broke in his little sister’s too-small pussy on his fat cock. any time he feels ashamed or lets better judgment stop him from giving in, you’ll remind him of this moment, tonguing and moaning and using brute strength to fuck you against the wall. you’ll happily use his guilt against him so you can use his cock as your own personal dildo and pacifier, forever. you moan just thinking about it as his pelvis bumps against your clit.
you hug him closer, your bare chest against his as you take everything he gives you. the pain is subsiding, but you don’t mind that it lingers along with the growing pleasure. you’re too stupid to care much about anything than getting him to fill you up with his hot cum. you hear the wet squelching of your pussy, his groans mixed with your high-pitched whines, the loud claps of his balls against your skin. they must be so heavy, so achey and so full.
you break the kiss, gasping and crying with your head against the wall. your legs are starting to shake, his fat tip brushing against the sensitive spot inside you that pushes you towards the edge.
“i’m… i’m gonna cum!” you pant, throwing your head back as your limbs all coil like a spring. “oh, oh, feels s-so good, love my big brother’s cock— ah!” you whine, crying out because his grip on your thighs tightens. you know you’ll have imprints of his fingers there for weeks.
“i know you do, baby, fuck.” he grunts. “cum on it, then. cum for your big brother.”
that’s all it takes. you cry, clamping down on his thick member rhythmically as your body shakes. it’s blinding, like nothing you’ve ever felt before with your own fingers or whatever you could hope to stuff yourself full of in the middle of the night that might mimic your big brother’s size. he lets you ride it out, his pace unrelenting to prolong it for you. you feel so good, and you look so pretty cumming around him that he doesn’t really notice your nails digging into his neck and clawing at him to ease up. he can’t— he sees how it drains you, and he feels so bad, but he needs you to hold out a little longer.
you keep bucking your hips to keep his cock nestled inside you as he walks backwards towards the bed behind him, still holding you safely in his arms. but the shift in angle as he flops down and makes you sit on his cock nearly makes you scream. gravity is working against you, fully impaling you on his long, thick cock, but you don’t have time to adjust because his large hands are on your hips in seconds, lifting and dropping you to make you bounce up and down on it.
“that’s it, take it all. make your big brother cum, baby, i’m so close.”
the closer he gets to spilling his seed inside you, the less guilty he feels, so your tears don’t do much except spur him on in the moment. even your begging for him to stop, please stop, it’s too much! don’t sway him from what he’s already determined to do. you asked for it, literally. and you’re such a fucking brat. tormenting him for this, then crying and thrashing once he really gives it to you. he cares that it’s hurting you, overstimulating you and making you cry harder than he’s seen in years— really, he does. but he’s so close. he can’t bring himself to stop driving you down onto his throbbing cock, and you’re too weak to put up the fight it would take to get out of his grip. but you’re a good girl, the best little sister anyone can ask for. you resign to it eventually, and before you know it you’re bouncing on it yourself, babbling with your head thrown back that you’re going to cum again. he is, too.
he holds you down firmly as he drives his hips up into you, and the scream you try to let out sounds more like a strangled cry. you claw at him, back arched as he pushes into you, so deep that you feel him in your guts. you look down and you see him, his fat cock causing a slight bulge in your tummy, your legs and pussy spread wide just to accommodate his width. he sees it, too, and he nearly blacks out as he shoots his heavy load up into you, finally releasing what’s been pent up for as long as he can remember. you ride him through it, using his pelvis to keep nudging against your puffy clit, ignoring the pain deep in your core until you cum again with a jerk, falling onto his chest with his cock still splitting you open and leaking his seed into you.
he wraps his big arms around you, soothing you because he knows it’s a lot. you’re trembling head to toe, all twitchy because you’re so sensitive, but you still moan when he kisses you open-mouthed and passionately, your tongues sliding across one another as he rocks into you until his balls are completely drained. he’ll keep you like this for a while, he thinks selfishly. keep his cum inside you, his still ridiculously thick cock keeping you plugged so none of it can leak out. he’d already lost the good fight against his resolve to not be a little sister fucker, so he really has nothing to lose anymore. he’s no longer denying the fact that he loves his baby sister just a little too much.
step brother eren finding you passed out after touching yourself to sleep, all naked and soaking. ready for him to flip you over and slide his cock right into you with little to no resistance. it’s satisfying to your sleeping body that’s still so needy, because your stupidly small fingers never really could get the job done. but now you’re relaxing into taking something that was meant to make you cum, designed to keep you full and stuffed and bred. a long, thick cock curved specially to slot into you and nudge every sensitive part that makes you twitch and moan.
and it’s your fucking fault. what kind of slut falls asleep naked and compromised for her big brother to find? he doesn’t mind if you wake up from his increasingly hard pounding into your soaked pussy. in fact, he’s happy when you do, because now you know the consequences of being such a stupid, slutty little sister. you’re still disoriented, not putting up much of a fight because ditzy, needy girls like you go fucking dumb on cock like his, already moaning and squeezing down on him as your legs shake. he pins your arms behind your back with one of his big hands to keep you from squirming too much, with the other wrapped firmly around your throat, threatening to put you right back to sleep if you put up so much as a fraction of resistance. but you don’t, because you’re already cumming from your mean older brother using you this way, satisfying your needs the way only a real thick, veiny big brother cock could.
his grip on your throat tightens enough to silence your cries almost completely, and you black out again just as soon as you feel his warm cum start to leak out against your cervix. it’s comforting, makes you feel all warm and full, and you’re out before you know it. he throws his head back when he feels you go limp again, moving his hands to your hips to hold them still as he ruts into you over and over. he savors the soft noises of your wet pussy sucking him in, milking his cock until his heavy balls are emptied. and he’s still hard when he’s finished, already trying to wake you up for round 2 because there’s nothing you can do to stop him and his little sister’s pussy just feels so good.
