#tw stepcest

i NEED stepsis!becky who’s like. older than you and like, genuinely makes you feel so good the first time she touches you that you don’t want anyone else ever.

thinking about her toying with your cunt as your body is practically on fire, whispering for her to stop and that she shouldn’t do this but she just doesn’t stop.

“why would i stop when my darling stepsis is getting so wet from a couple of touches?” she’d coo, brushing a couple of strands of hair from your eyes as she pushes a finger into your soaking hole, watching how your walls clench down on the digit so hard.

“becky….” you whine, before biting your lip so hard that it nearly bleeds from the pressure.

“god, you’re so gorgeous,” your stepsister sighs as she adds another finger into your pussy, before angling her head down and spitting onto your clit, letting her spit mix with your slick coating her manicured fingers.

“that feels— ah, so good,” you whimper, looking at becky with a pout as you start rocking your hips into her pumping fingers.

“what a horny little bitch you are, stepsis,” she laughs evilly, whilst she uses your cunt to her heart’s content, “you’re soooo disgusting for wanting this, honey. for letting your stepsister use and touch your pussy like this,” she adds, only to be met by a pathetic whine from your lips.

she then goes onto degrade you for a couple more minutes before you come on her fingers, your juices dripping down her hand as she slowly removes her fingers from your spasming hole.

Sukuna has surprisingly left you alone for a few days. By the time you wake up in the morning he’s already out the door and gone to practice. During the rare times he joined the family for dinner he minded his own business and was even polite, as much as he was capable of, towards your mother.

It made you feel as if you were losing your mind. Was the animosity one sided? Was he truly being antagonistic towards you this whole time or was it something you projected onto him?

Now you’re having dinner with everyone and Sukuna walks in late. He’s limping and has crutches under his arm. Your instinct is to help him but you catch yourself, nothing good will come from engaging with him.

“Oh sweetheart, what happened?” Your mother asks, concerned.

“Twisted my ankle, might be a torn ligament. The coach fuckin’ benched me for two weeks.” Sukuna huffed as he slumped in the chair next to you, taking the plate your mother hands him with a nod. “I might be out longer if it doesn’t get better.”

Jin’s face lights up, eager to share his news with everyone. “That works out perfectly, doesn’t it honey?” He looks over to your mom who nods back with enthusiasm. “We need someone to watch the house while we're gone for a week.”

“Darling,” your mom faces your confused expression, “Jin and I have been putting off our honeymoon for a little while now and we realized that our schedules will finally align next week. So we’re finally making it to Bali!” Her excitement reaches your ears but you only take in the fact that your safeguards will be thousands of miles away.

Jin takes over just as your face falls, worried about how many responsibilities you’re going to have stacked on your already full plate with them gone. “Yuji is going to stay with the Fushiguro’s for the week and Choso said he is going to take this opportunity to visit Yuki since she moved out of the city.”

Everything suddenly got worse. Yuji and Choso being a constant presence in the home was always a buffer, not as much as your mother was, but still a way to keep Sukuna in line. With them gone you didn’t even want to imagine how his behavior was going to escalate.

“Don’t worry, honey! Jin and I will fill the fridge with plenty of food before we go, and you can always just order food while we're gone, we’ll leave you some money. And now with Sukuna injured, we really do need someone capable of taking care of the home.”

Sukuna says nothing and keeps his face unmoving but the way his eyes glance over you tells you that he’s reveling in the news. There was no getting out of this and once again the idea of ruining your mom’s fairy tale weighed heavily on your mind.

“Besides,” your mom continues on, “Sukuna tells me that you both have started to get along! I’m so glad that you’ve been trying to make our little family work.” Her voice is so cheerful it almost sounds foreign. You can’t burst her bubble now, not yet at least.

“Sure thing, mom.” You nod and try to occupy your mind with something else.

You politely sit and listen to the way your mother gushes about the resort they are going to be staying at and how she can’t wait to pack. Sukuna nudges your leg with his to get your attention. You’re met with a raised brow and a nod towards the hallway of your bedrooms. A sneer graces your features and you gather your plate, appetite ruined.

“I’m not feeling very well. I’m gonna shower and head to bed early.” You say before receiving a nod from your mother. She offers you a kiss on the cheek and asks you to help her pick out a vacation wardrobe tomorrow when you feel better.

As the warm shower water cascades down your back you can’t stop your mind from reeling. Flashes of Sukuna pinning you down and ravishing you while the house is empty won’t leave your mind no matter how much you try to shift your focus.

More than anything else, you hate how you feel yourself getting so worked up over the thought of what he had planned for you. You had to remind yourself that he backed off since that night he climbed in your bed; maybe he got it out of his system, maybe he found someone else to bother.

A strange feeling curled in your stomach at the thought, an ugly feeling of jealousy and possession. That made you feel worse than anything Sukuna himself had done.

You shut the water off and wrap a towel around yourself, upset that the time alone did little to soothe your frazzled mind. As you reach the door to your room you aren’t prepared to be met with Sukuna rummaging through your drawers.

You can still hear Yuji and Choso speaking with your parents on the other side of the house. You quickly close the door behind you so you can speak clearly without someone else listening in.

“What the hell are you doing in here? Get out!”

“I need my nurse to help me again.” Sukuna says while pulling out a pair of lacy underwear from the neat pile inside your dresser. “Oh, you’re definitely wearing this for me when mom and dad are gone.”

“You’re sick.” You spit, disgust marring your features as he pockets a different pair. “And she’s not your mom, don’t call her that.”

“Lock that door,” he nods his head towards it. “I’ve had a shit day and you’re going to make it better for me.”

“I’d rather die.”

“Is that so?” He challenges. “Then go tell your mom what you think of me, right now. Tell her that you hate me, that you think I’m a demon that’s ruining your life. We’ll see how fast that little honeymoon is canceled."

You stand still, teeth biting down on your inner cheek to keep your emotions in check.

“And don’t forget how disappointed in you she’s gonna be. You have no idea how many times she’s told me she’s ‘so proud of us for getting along’ over breakfast. Yuji too. He’d be heartbroken to learn that this family isn’t going to work out. Choso doesn’t say it but you’re probably his only friend outside of Yuji and Yuki.” Sukuna shrugs like what he said means nothing. “Ya’ know, your choice.”

You couldn’t control the wobble in your voice, not even from fear or frustration. His mere presence brought out a side of you that felt meek and helpless, and it made you all the angrier at him.

“I need to get dressed first.” You’re still dripping water onto your floor as the towel wrapped around you soaks up as much as it can handle.

Sukuna simply shakes his head and leans back against the headboard of your bed. With a grunt he stretches out his injured leg and pats the small empty space he left for you on the mattress.

“Leave the towel and get your ass over here.”

His face grows bored the longer you spend deciding what to do. The idea of him growing tired of you is the catalyst for you locking the door and hanging your towel to dry over the knob. You hate that you care about what he thinks and does, but there’s no time to think about that now when you catch the way his throat bobs up and down with a swallow as you approach him fully exposed.

“I didn’t really get a chance to see how pretty my sister’s pussy was last time.”

He grabs your phone off the nightstand and wraps an arm around your shoulder as you sit next to him. An attempt to make space between you both is proven to be useless as he scooches you closer to him, his body heat warming your damp, chilled skin.

Sukuna places your phone directly in front of you, unlocking it automatically as it scans your face. You try to grab the device from him but a sharp swat on your backside stops your fussing. “I already told you, we’re gonna swap videos and we’re doing it now. You wanna go first, or should I?”

“I do not wanna see what depraved shit you’ve been getting off to.” You reply.

“Well… I was gonna come in here and fuck you until the whole house hears you screaming my name but I can’t really chase after you when I’m like this.” He gestures to his elevated ankle. “So watching my depraved shit is what you’re gonna have to do, baby sister. What will it be? You or me first?”

You mull it over in your mind, the last thing you wanted was for him to go through your search history. You never had to hide it before moving in with the Itadori’s, so God only knows what you have bookmarked or saved.

“Ugh, you go first.”

“Oh princess, I didn’t know you were so eager to find out my kinks.” Sukuna’s smile was deadly as he gloated.

“You’re beyond delusional.” You retort, watching anxiously as he casts your phone aside and pulls his own out.

“I’ve been planning this for days, sis. I think you’re gonna like this one a lot.” Sukuna smiles as he rotates the phone horizontally.

You’re unable to move much as his arm holds you even tighter against his side while the video starts. You all but jump as the first noise you hear from the speaker is a woman crying out in pain. Said woman is bent over a leather bench, her round ass in the air and already glowing red under the dim lights.

A man walks around her and fists her hair into a makeshift ponytail. As the camera pans to the front of her bent form, you watch as her mouth opens and tears streak down her face. The man’s cock is shoved down her throat and the muffled sounds of her wet gagging echo out.

A gloved hand smacks her ass cheek and you can’t help the way your heart beats loudly at the visuals of her mouth being used. You’re so entranced by the way the man spanks her once again that you don’t notice Sukuna handing your phone to you until the heavy object lands on your abdomen.

“Your turn.” Sukuna looks more than satisfied by the expression on your face, the slight glaze over your eyes. “Unless you want to finish the video?”

“No!” You say a bit too quickly. “I’ll find something.”

“And no bullshitting me either.” Sukuna warns. “I’ve seen some of your searches, show me something good.”

You open your browser app and much to your misfortune you still have a tab open on your private setting.

“Fuck, were you watching this last night or somethin’?” Sukuna teases but genuine curiosity peaks through his words.

“I’m gonna find another one just give me a minute-” The phone was pulled from your grasp followed by Sukuna starting the video you left open.

The video was already halfway viewed and the scene that was resumed had you mortified. The female actor was being held up in the shower as her significantly taller male costar pounded into her from behind. Her legs dangled as she hovered, solely being supported by his bulky arms wrapped around her midsection and the hands she planted against the shower tiles.

“Okay you saw it.” You wanted to claw your eyes out, maybe his too. “Just show me another one of your perverted ones.”

You wanted to move on quickly. Not because the video was particularly shameful, really it was just a size difference kink being shown, but because you didn’t want him seeing the true reason you clicked the video to begin with. It disgusted you to think about but your brain with its late night urges has never had the best judgement.

Sukuna looked a bit uninterested in the video until the actors shifted to the other side of the shower where the camera panned out to show more than just a closeup of the actress. His garnet eyes widening before a toothy grin broke out on his face.

You feel sick as you see the male actor’s body, knowing that Sukuna was taking in the very detail that made you pause your scrolling and watch it last night.

Not only was the actor’s body sculpted and built intimidatingly large but the tattoo’s he sported, though not exactly the same, had a resemblance to Sukuna’s tattoo’s. Twin black bands across his thigh and bicep. The other tattoos on his body were of their own style but it was undeniable that a few more were also similar to the man laying next to you.

“No fucking way.” Sukuna looked at you incredulously.

“That’s not why I watched it.” Your rebuttal was useless, his ego was already inflated.

“Yes it fucking is. This is perfect; you’re perfect.” He said with such arrogance you wanted to punch him. “You’re gonna love this next one.”

“I would love it if you left my room.”

“So that’s why you wanted to change the video so badly?" Sukuna laughed at your misery, reveling in your discomfort.

You cursed him under your breath and waited as he pulled the next one up on his phone.

Your face fell flat as soon as the thumbnail and description popped up on the small screen. “SLUTTY STEPSIS BEGS FOR DEEP CREAMPIE” 

“You don’t actually watch this shit, do you?” You ask while the most obvious and cheesy porn lines are spoken between both actors. 

“I didn’t before, but I’ve been inspired lately. I prefer them more bound and gagged, a bit like you do, baby sister, but the plot of this one is pretty good.”

You say nothing as you note that the actress shares the same coloring as your own hair and eyes, trying not to dwell on that. Likely just a coincidence that she also has a similar build to your own.

Her legs are pinned back as her “step bro” fucks her in long deep strokes. “Fuck! Bro you’re gonna get me pregnant!” she moans out as the thrusting speeds up. You are far too aware of your own body right now; how fast you're breathing in, how your cheeks warm up, how your body thrums at the, admittedly poor quality, clip.

You’re finding it harder and harder to focus, eyes slipping down past the phone in Sukuna’s large hand only to catch an eyeful of the heavy bulge poking out between his legs. It takes every ounce of control to not groan at the idea of grinding yourself on his thick cock again.

“If you’d rather just have me fuck you, you can say it, you know?”

He definitely caught you staring. But between the heat radiating off of him and the moaning coming from the speakers, you couldn’t be bothered to fight him on the allegation.

“Fuck off.”

“Give me your phone.” He says.

You hand it over without a fight, unlocked and all. Maybe your walls were worn down by his persistence or maybe you were just exhausted from being teased by the videos he had been playing. You didn’t want to think about another option that could be at play; the idea that you are enjoying his twisted attention.

He’s scrolling through your tabs and bookmarks until he lands on one that piques his interests.

The video opens up with its all too familiar intro for the porn studio, and like a pavlovian dog, your clit throbs in anticipation from the sound alone. The scene starts with the actress tied face down to a bed, ass arched high in the air, wearing nothing but a pair of stiletto heels and ropes on her arms.

She’s gagged and looks worried as the male actor enters the scene. He has a leather riding crop in hand and circles her once before striking it across her ass. Her attempts to move her torso away from the strike only earns her another swat, this time across thighs.

The actor has a wand vibrator in hand and holds it against her slit, teasing her sex while alternating between spanking her with a wide palm and whipping her with the crop. She pleads with him, begging through the ball gag for permission to cum as the vibrations get more intense.

“I knew we were alike.” He says presumptuously. “Touch yourself for me.” When you hesitate and don’t move fast enough he adds, “do it or I’ll fuck you and record it. I’ll send it to your mom.”

His threats felt like a gun to the head, so you follow his orders.

Sukuna feels you shifting and takes that as his cue to adjust himself as well. He removes his arm from around you to pull his loose pants down. Your eyes flicker between the screen and the way he begins to slowly fist his cock.

The woman in the video is moaning and drooling as she’s getting fucked, the vibrator tortuously being held against her swollen cunt. The double visuals in front of you make you dizzy with need.

You carefully move your hand down your exposed body and circle your clit. You wanted to get a hold of yourself, to stop your hands from moving and your body from reacting, but you couldn’t be helped now.

Sukuna has seen the porn you watch, and for fuck's sake you remind yourself, you came on his cock already; you can’t get much lower than that.

The man in the video begins inserting a toy inside her other hole as he rams his length inside of her, stuffing her full as she continues to cry out in an overwhelming mix of pain and pleasure.

“Sit on my face.” Sukuna whines out, completely drowning in his own lust.

You’re hardly able to be pulled out of your trance, eyes too focused on the way the actress squirts after a particularly harsh thrust. “Huh?”

“Come on! Get your ass up here or I’ll fuck your throat and leave instead.”

Without a second thought you climb over him while he slides down flat on your mattress. Two warm hands pull you down onto his mouth as the phone and video playing are tossed aside and forgotten about.

Everything about him is big; his body, his cock, even his tongue. The warm muscle slides through your wet slit, covering every inch of you as it moves back and forth. You grind yourself down on him as his tongue sinks inside your pussy, thinking to yourself that if he suffocates to death down there that it is a solution, not a problem.

It doesn’t take much to make your body feel like a live wire is running through you. After half an hour of tension and teasing while watching other people fuck on camera, you are so worked up that just the warmth of his tongue has you panting and moaning.

“I hate you. I hate you.” You chant while chasing your end. He was too talented with his mouth, knowing just when to let up and when to increase the pressure on your clit.

You tense and grip his messy pink hair with one hand, the other one brought to your mouth to bite back your moans. But the high doesn’t last, you’re pulled from the edge of a climax by him lifting you off of his face.

“If you wanna cum, you gotta suck me off, got it?”

Too fucked out of your mind, too close to care you, nod quickly.

“Fine! Just shut up and let me cum-” You squeak out as he positions you to face away from him while still arching over his body.

His hand lands on your ass, the stinging blow causing you to buck away from his touch. A sequence of smacks follow you as you attempt to escape his hand.

You never hated how large he was more than in this moment. Arms that could wrap around you with ease, hands that gripped your hair without him straining to even sit up. You were held in place as he reddened your right cheek with hand prints.

“Don’t pretend you don’t like this.” Sukuna taunts as he tugs your hair a little tighter for emphasis. “I could hold you down and fuck this ass raw and you’d still cum for me.”

You knew that placidity he showed all week was just masking the evil shit he wanted to do to you. You also knew that every word he spoke had some truth behind it. 

“Get your mouth to work, I’ve got something I wanna test out.” Sukuna says before he wraps his lips around your clit and suctions against the aching bud.

You lick his leaking tip with the flat of your tongue, tracing the weeping slit while fisting his shaft. It’s an awkward balancing act as you try to stay arched with only one hand on the bed. It takes you a moment to get used to stretching your jaw around his girth but the feeling of his lips and tongue alternating their movement on your bud ease you into it.

Sukuna switches between using his hands to whack the supple flesh of your thighs and to shove two thick digits deep inside your cunt. You’re leaking down his face and each pump of those rough fingers have you moaning around the cock in your mouth.

“Such a good girl for her big brother.” He delights in the way you’re unable to hide how your walls clench at his words, sucking his fingers even deeper inside of you without meaning to. “I could do anything I want to you and you’d let me, wouldn’t you?”

You panic as one long thick finger leaves your pussy to circle the tight rim adjacent to it, teasing the entrance with how slick the digit is from your essence.

“Don’t touch me there. Stop!” You gasp for air as you turn your head back, trying to meet his eyes, pleading.

All you’re met with is a scowl and deeply blown out pupils, high off lust and power.

“If you pull your mouth off my cock one more time I will fuck this ass dry.”

As your mouth returns to his length, his digits thrust back inside your pussy. The threat of him ravaging you still weighs heavy on your mind. There was no such thing as an empty threat with Sukuna.

The occasional swipe of his tongue upwards had you mewling. A long wet trail of his wet muscle from your clit to your ass makes your legs shake unexpectedly. Thankfully that’s all it remains, an occasional nod, a reminder of his promise.

The action has you strung tight once again, each swirl of tongue and brush of his lips pulling you closer to the edge. You can’t hold back your moans any longer, suddenly thankful for the cock that is prodding your throat for muffling the sounds. As you reach your peak you feel your body release more and more slick.

Your hands clench on Sukuna’s thighs as you cum on his hand and in his mouth. You try to shift off of him when your crescendo ebbs but his mouth remains in place. You’re simultaneously afraid to stop sucking him off but you can’t handle the feeling of your throbbing clit being stimulated any longer.

You double your efforts with your mouth, tongue swirling around the tip and fist rotating around the shaft with each bob of your head. Sukuna’s body goes rigid as he tries to fight off his own release and it becomes a challenge of who can finish first.

Despite focusing on anything but your own body, you feel heat creeping through you once again. Pushing aside the urge to gag and cough, you take him as deep down your throat as you can manage, your moans vibrating the sensitive tip that slides past your uvula.

Sukuna grunts and presses his tongue harder against your clit, a mess of spit and cum sliding around as he works his mouth to exhaustion.

You can’t be sure, mind too foggy to think clearly, but you think it’s you who cums first, rocking your hips as if they weren’t seconds away from collapsing under the stress of holding yourself up for so long. Sukuna finishes down your throat, milky streams that seem to never end, before you pull yourself free and finally catch your breath.

“No more. I can’t-” you try to swat Sukuna away as his fingers replace his mouth on your throbbing slit.

“Of course you can. Your pussy speaks to me ‘ya know,” his fingers furiously slide back and forth over your overly sensitive clit, “and right now she’s saying I can get her to squirt in about two more orgasms.”

“I’ve never-, I don’t think I can.” You are feeling weak down to the bone, left with hardly enough strength to wipe the drool and cum that runs down your chin. “Please don’t.”

“I’ll make you a deal,” Sukuna offers. “You just need to cum one more time for me. If I’m right and I can get you to squirt, then we get to do this every night until mom and dad leave for their honeymoon; If you can’t do it, then I’ll leave you alone… until mom and dad go on their honeymoon.”

“I can’t.” You groan with desperation, tears welling in your eyes as your body twitches at the constant contact of his hand. “I can’t.”

Sukuna rolls you over onto your back and spreads your legs. He spends a moment taking in the sight of your messy folds, swollen and glistening. You feel him as he lines his already semi-hard cock up with your asshole while folding your knees to your chest. “I’ll just fuck you then.”

“No! I’ll do it! I’ll let you do it! Please don’t-” You beg.

“I don’t know, this seems like more fun. I can’t get enough of that look on your face right now.”

You feel a nudge against your tight rim and get desperate. He’s too thick, too large to fit even if you were prepped and stretched. The idea of him taking you right now with only the minimal slick that dripped down made you scared, like a caged rabbit dangled in front of a starved wolf.

“Please, big brother. I want you to make me squirt, make me cum. I’ll take anything, please, just don’t fuck me there.” You cry desperately, willing to say anything that will pull him back.

Sukuna lights up as you call him that. “You want your big brother to make you cum? Want me to take care of you?”

You nod, too ashamed and disgusted by the words you’ve already spoken to say anything more. You’re confident that nothing will happen, you’ve even tried it on yourself before. Squirting is just a function you did not possess. 

Your fingers grip the bed sheets as he works both hands on you. One hand is curling three digits upwards inside your pussy while the other hand rolls your clit back and forth. It’s taking no time at all for the sensations to build higher and higher.

Lolling your head side to side, you moan as his movements become faster. He taunts you as the pressure in your abdomen increases. You are just lucid enough to hear him brag that you’re going to lose and that he will enjoy every second of your time together once he wins.

Juices make an audible splashing noise as you feel your legs shake, your whole body shivering and convulsing. A warmth, growing larger and larger like a bubble, settles over your body. You can’t breathe, everything is too tense, too tight.

With wide eyes you feel it. Warm liquid spraying down your legs that has you gasping for air. Sukuna groans as your body releases itself in a new way. So over-stimulated that you can’t even sense when he removes his hands from inside of you. All you can feel is the aches in your hips and the heavy throbbing of your body.

“I told you. Your pussy speaks to me, and she’s a lot more truthful than you are, little sister.”

“I hope you rot in hell.” You are barely able to speak but your spite wins against exhaustion.

Drunk step-dad! Leon stumbles into the house late, clearly drunk and horny. He doesn’t even bother kicking off his shoes before he bursts into your room and jumps straight onto the bed, crawling over you with a big, goofy grin. Thankfully it’s just you two in the house. He peppers your face with sloppy, eager kisses, humming happily against your skin.

“Oh, my sweet girl… Daddy missed you so much,” he murmurs, his voice warm and low. He gently squeezes your cheeks together before leaning in for a deep, messy kiss, devouring your lips like they’re his favorite candy.

“D-Daddy!” you giggle, and the sound makes him smile against your mouth.

“Ah, you like that, yeah?” He nips at your bottom lip, then soothes it with his tongue.

His hand slides under the oversized t-shirt you’re wearing—his shirt—and he slowly peels it off you. The second your breasts are bare, he lets out a low, drunk chuckle, eyes darkening with lust.

“Look at those pretty tits… all mine.”

He wraps his lips around one hardened nipple, sucking greedily while his hand kneads the other. His tongue swirls and flicks, sending sparks through you, and when he gives the sensitive peak a firm little squeeze between his fingers, a sweet moan slips out of you.

“Yeah, sing for Daddy,” he groans, clearly loving every sound you make.

Still kissing and licking your breasts, he unbuckles his belt with one hand. His other hand slips into your panties, fingers finding your clit and rubbing slow, teasing circles. You feel him free his hard cock, already leaking, and he strokes himself a few times while watching you.

He hooks his fingers into the waistband of your cute strawberry panties and tugs them down your legs.

“My angel always wears such cute little panties,” he says fondly, voice thick with affection and want.

“Only for you.” you say sweetly, in response he squeezes your cheek playfully.

He lines himself up, the blunt head of his cock pressing against your slick entrance.

“It’s gonna take me a while to come, darling… drank too much tonight,” he warns with a lazy grin.

Then he slowly pushes in, stretching you open inch by inch while letting out a deep, satisfied groan.

“Ohh, Daddy…” you whisper breathlessly.

“You missed my cock inside you, didn’t you, sweet pie?” he teases, voice husky.
