Sukuna never tried to hide his lack of morals from anyone, wearing the trait instead as a badge of honor. He reveled in the way others would whisper about him as they watched him out of the corner of their eye, steering their daughters away from him because they knew what he was like. Everyone saw the way he looked at you, his own daughter—lidded eyes that stared for longer than they should, shamelessly ogling what he considered to be the best parts of you. 

When his friends would comment about how well you "filled out" after you grew up, he wouldn't chide them. He'd just laugh and agree. 

"She's mine, course she looks good." 

What people didn't see was how much you fed into his behavior. It was a secret piece of knowledge that Sukuna kept to himself, not wanting to risk it getting out to the wrong people… like your mother. 

You were the only good thing that came from his union with "that woman," as he called her. 

His perfect daughter that never wore pants around the house, opting instead for a pair of panties and a tank top. You were so sweet to him, bending over in the fridge to give him a nice show while he had his breakfast. Sleeping naked with the door opened so when jerked off he could get a view of your bare pussy, still slick from touching yourself—preferring his hand and the idea of his daughter over the body of his wife. 

But as perfect as you are, you sure as shit know how to piss your old man off. 

Veins are bulging in his hand from how hard he's gripping his phone, glaring down at the screen as he replays the video you sent him for the fifth time. Your high pitched moans are flowing from the speaker, all whiny and desperate, as whoever you're with points the camera right at the place where he's sliding inside you. The flash is on, giving Sukuna almost too good of a view of the way your virgin cunt is swallowing the boy's underwhelming length. 

Slut.

That was the first word that came to his mind when he'd opened your message—"my first time :)"

"Home. Now." He'd replied curtly. 

Your knees are aching from being pressed into the floorboards for so long, but they don't hurt nearly as much as your jaw which has been stretched wide for the same amount of time. Sukuna pushed you to his feet less than a minute after you walked through the door, slapping you once across the face with a single command to 'open up.' 

The gags coming from where you're choking on his dick between his legs are merely a distraction as he watches the pathetic way you're getting fucked on camera. 

"You could've just asked if ya wanted your daddy to fuck you like a whore," Sukuna's anger is evident in his tone and the way he presses his cock impossibly harder into the back of your throat. 

Your nose is buried in his untrimmed bush, his natural musk filling your nose as you struggle to breathe. Drool is already spilling from your lips and down to his heavy balls from how long you've been forced to cockwarm the man with your little mouth. 

Sukuna finally closes out of the video, opting to open his own camera now. He makes sure you're captured in the middle of the frame, the flash on as well so he can see the pretty tears in your eyes, the sweat on your skin, the way his dick is shoved between his bratty daughter's lips. "You look good like this, baby. On your knees, mouth filled with my cock," Sukuna muses. "Got you to shut up too. Might have to show Fushiguro."

Sukuna grins wickedly when he sees the way your eyes widen. You don't know what you'd do if a photo like that got out—the tell-tale tattoos around your father's thighs being particularly incriminating. 

"What? Now you don't like bein' in the spotlight?" he goads, pulling you off of him until just the tip rests on your tongue. You're coughing immediately, but the second you're about to take your first real breath of air, Sukuna is thrusting back down your throat.

"Yeah, get my dick nice and wet like that—gonna regret it if you don't. Means it'll hurt more when I fuck your ass." 

"Mmmfg!" is what your strangled attempt at protest sounds like. Even if you could get a word out, Sukuna wouldn't listen. You lost the right to him treating you nicely when you pulled your stupid stunt. 

"You wanna go 'round whoring yourself out on camera, then you'll get fucked the way you deserve," Sukuna all but snarls at you before finally yanking you off of him for good. With one last shove, he sends you tumbling into the ground at his feet.

You hit the floor hard, your palms stinging from attempting to catch yourself. The whole time, Sukuna just stands there. With his cock in his hand, he's pumping himself slowly as he gets off on the way your naked form is sprawled out before him, trying to recuperate. "Face down, ass up, and spread yourself open f'me." 

You scramble to do as he says, not daring to talk back with how stern his voice is. When you're finally presenting yourself to Sukuna how he asked, he wastes no time kneeling behind you, the head of his cock already kissing your entrance. 

"Wait, dad, condom." You remember when you feel the warmth of his tip rubbing along your slit, smearing his pre into the arousal that already gathered there from him using your mouth. 

"You really gonna tell your old man to wrap it up? Don't act like a fuckin' prude when I know you didn't use one with that kid." 

He's right. But it's not the same, because 'that kid' isn't Sukuna. He isn't your own flesh and blood like the man behind you, slamming into your sweet cunt with a single punishing motion. 

Your face rubs painfully against wood floor as you're sent forward with the force of his thrust. "Aah, fuck!" you wail, but Sukuna dismisses you immediately. The weak "Ow…" you let out after must have sounded too close to a moan for him to care. 

The way your pussy feels so good around his dick almost makes Sukuna want to go easy on you, remembering how much he cares about his daugther. 

Almost.

And then remembers that he's not the first person to know what your cunt feels like, and any hopes of being shown mercy from your dad melt away. He sets a pace so brutal that you're trying to crawl away from him, only for him to grab your hips tighter and pull you back. Judging by the footage of your only experience, Sukuna knows you can't handle it and that only makes him want to go harder. 

You're whimpering so cutely, cheeks wet from tears and your lips from the saliva that keeps spilling from them. Everything burns. The stretch from your dad's fat cock inside your tight pussy, your already sore knees now starting to bruise, your neck stiffening as your head is bent at an uncomfortable angle. There's no plush mattress, no cushiony pillows to make you feel better as Sukuna pounds you into the floor so hard you think it might splinter into your skin. 

Through it all, there's nothing you can do to prevent the lewd sounds that are slipping out of your mouth with a messy amount of drool that only makes you look even more like a pornstar. Deep down, you love this, he knows you do. You internalize all the insults that Sukuna throws your way because it makes the occasional praise he sings sound that much louder. Just as with the immense pain he's inflicting upon you, it only serves to make the pleasure that much better. 

Your orgasm is building too quick for your own brain to keep up, rapidly reducing you to a puddle of moans and cries for the man that's destroying you.

"Daddy! I—ohh fuck, I'm," you mewl, eyes rolling back as your cunt starts to throb around Sukuna's girth.

"Yeah, I know," Sukuna grunts. Your hazy mind can hardly comprehend what he's doing when you feel him shifting around you. He adjusts his position with his cock inside you until your face is being trapped against the hardwood, pinned underneath Sukuna's bare foot. 

The new angle is too much. No longer rutting forward into you, Sukuna is slamming down onto you, splitting you in half on his cock as he forces it unbelievably deeper inside you. 

"Ohmygod, ohmygod, I can't," you sob, chest heaving as you cry harder. "Too deep, dad, wait—" 

"Save it," he snaps at you. "This cunt is cryin' more than you, I know ya love getting used like the pretty slut you are. You're fucked in the head just like me." 

He's not wrong. Within moments you're cumming so hard that you think you might pass out, your legs shaking uncontrollably as Sukuna finally starts to slow down. 

"See? Makin' a god damn mess too." Sukuna sneers as he watches the way your pussy is starting to leak, creamy white slick coating his shaft as he slides out of you. "Your mom would be disappointed to know you turned out this way."

"Fuck off," you groan tiredly, not able to be bothered to care what your mother would think when you just had the best orgasm of your life. 

Sukuna chuckles as he steps off your head, moving instead to rub his hand between your folds, gathering your slick on two fingers. You wake up more when you feel him circling the rim of your asshole, prodding at the tight entrance with every couple swipes. 

"No, don't. I don't want to… not today," you try, having a feeling you wouldn't change Sukuna's mind.

He rolls his eyes, confirming your suspicions when he lazily pushes both fingers into your ass, ignoring the loud whine from you. "You say that but you don't mean it, look how well you're takin' these fingers. Can tell you want more." Sukuna slips his hand out of you before replacing them with the tip of his dick. "I know what my little girl needs." 

It's almost adorable the way your asshole clenches like that would stop him from fucking it. And the way you whimper another 'dad please, don't." Pathetic. 

When Sukuna presses his cock inside your tightest hole it's with an agonizing stretch. He didn't give you nearly enough prep to comfortably take someone of his size, and all of the cum and spit that's coating his monstrous length is doing nothing to ease the intrusion. 

A sound halfway between a scream and a croak escapes you as you crumble under Sukuna's weight, slumping into the hard floor beneath you for the second time tonight. 

"You need to loosen up, kid," he grunts, both hands spreading your cheeks apart to get a better view of his dick nudging inside your ass. The skin is taut and he can see the muscles tensing, trying to keep him out. It's causing him such difficulty that he wonders if it's even worth it as the friction starts to spread some of your pain to him. 

But it's the only part of you that hasn't been corrupted yet, and he'll be damned if another man gets to it first. 

"Fuck, it hurts," more tears pour from your eyes, dripping onto the ground below you. "Dad, I'm—am I bleeding?" You have to ask with the way it feels like you're being torn apart—you won't be surprised if the answer is yes.

"Nah, I'd fit inside a lot easier if you were though. Maybe you should," Sukuna muses, grinning when you writhe in his grip, trying to adjust to his size. "What, you don't want that?"

You're not even sure what you want. 

You want this all to be over. You want Sukuna to leave you alone and pretend you never started this whole thing. But you also want him to make you feel good in every way that he knows how, even when it hurts and you're not sure you can take it.

Because your knees are not only bruised but now scraped from sliding roughly against the wood with each thrust you had to endure. Your throat is sore from crying and shouting and gagging on your dad's cock. And still, your pussy is so soaked that it's leaking around nothing, producing more slick as Sukuna's hips inch to yours, until you're flush together once more.

"Never felt anything this tight," Sukuna groans, his entire length now buried inside your ass. It's so warm and squeezing him perfectly, he's not sure he'll ever want to fuck anything else again. With an experimental roll of his hips, his dick feels like it's pressing all the way into your stomach, making you whimper and squirm. 

The pressure is unparalleled. He's everywhere, overwhelming you from the inside out until all you can think of is him. 

All you can smell is his cologne and sweat. All you can hear are his grunts and groans, the sound of his skin slapping against yours when he pulls out half way before slamming back in. And all you can feel are his fingers digging into your flesh, his girth spreading you open so wide and deep that it's dizzying. 

"Play with yourself for me, baby." His voice is raspy, laced with exertion and strain from trying to hold himself together. Your body fits him much better than your mom's. "Told ya to loosen the fuck up," he lands a searing slap to your ass that makes you yelp. 

You have to lean onto your shoulder in order to snake a hand under you, reaching for your clit with a weak finger. Your neck is stiff, crooked at an awkward angle, and the poor thing feeling like it's going to snap when you try to look between your legs as your fumble around. Sukuna's moving faster now, reaching a steady rhythm that only serves to throw you off as you try to touch yourself. 

But eventually you find it—the right amount of pressure on that perfect spot which brings you just enough pleasure to forget all the ways in which your body feels like it's falling apart. Finally you relax just the slightest bit, allowing Sukuna to rut into you easier.

"Thaaat's it. See, feels good when you listen to your daddy." 

"Mmhng," you mewl, unable to find your words. You can't bring yourself to focus on anything more than trying to breathe through your punishment until you can get rewarded with another climax. 

"You let that boy fuck you here?" He already knows the answer.

"N-no," you reply, your voice shaking.

"Good," Sukuna growls. "Stupid girl. Fuckin' pissed me off today," he emphasizes the sentiment with another harsh slap to your ass. He puts all his strength into it, watching as the skin immediately starts to well up. 

He knows he's broken you completely when you don't even cry out at the impact, instead your breath just catches in your throat, followed by a sniffle. 

Tears and snot stain your face. Spit keeps pooling in your mouth and it seems like you're never able to swallow it all down, leaving some saliva to constantly dribble out between your lips and onto your chin. 

"Need a picture of this next time, should see how well this ass is takin' my dick. Knew we'd be perfect together." Sukuna is rambling on now, lost in his own thoughts as you're lost in your second approaching orgasm. "Made these holes just for me. No one else." 

Sukuna can feel the blood rushing in his ears, drowning out the rest of the room. He's teetering on the cusp of his orgasm, only holding on by a thread because he wants to bask in the feeling of you for as long as he can. 

But then you're cumming again. Shuddering and gasping on the floor as your arousal seeps onto your hand, sticky and warm. Your muscles tighten up so much it makes Sukuna hiss as you clamp down around his cock and he knows he's done for. 

"Should breed that pretty pussy, fill you up. You want that?" In a twisted sort of way, it's comical how quickly you panic, snapping out of your cockdrunk haze at his threat. 

"No! Please no, dad, you can't," you beg him, trying to appeal to the side of him that you know loves you as his favorite and only daughter. 

"You're lucky this hole feels so good," Sukuna grumbles, "fuck but you'd look so good pregnant with my kid—might even give me another girl. You don't wanna share your daddy with a sister?" 

You don't. You don't want to share him with anyone. That much is clear when you feel his hips still, his balls twitching once before he's spilling inside you. It's a weird but addictive feeling when warm spurts of cum begin to coat your insides, making it easy for Sukuna to finally slide out of you. 

The worst part of you wishes that your mom wasn't even in the picture. You would be fine with just Sukuna to take care of you, relying only on him and knowing that he only has you too. 

"Shit, look at that," Sukuna breathes, admiring the way your gaping hole is now leaking white spend. It's thick and slow as it slides down towards your cunt. 

He can't help himself when he reaches forward, gathering as much of his seed as he can onto his fingers and pushing them inside your pussy. Sukuna doesn't stop until he's reached the last knuckle, reaching as deep as he can. 

"What…" you cough, the fatigue finally catching up to you as your eyelids grow heavy. "What are you doing?"

"Just couldn't waste it," Sukuna murmurs, pumping his fingers languidly in and out of you. You look so spent, your skin bruised and red, your pussy lips all puffy and sore and smothered in slick. 

If you were all his, he'd make sure you looked like this everyday.

Come next morning when you wake up in your bed, your body shows the evidence of your night though red scratches and purple splotches. But you've been showered and tucked under the sheets, a testament to how gently Sukuna cleaned you up and brought you back to your room. It was confusing after he'd treated you so roughly. 

Maybe he felt bad.

But then you remember the way he pushed more and more of his release into your cunt despite your tired moans of protest. And when you try to tell yourself that it will be okay because it's different than if he'd really came inside you, you remember what he said when he laid you down for bed—about how he got your mom pregnant on their first night together.

His order were absolute as your body obey. Tilting you face back only to have him surging forward to lock your lips with his. Biting into the low of your lip, a cry of pain slipped out your throat as he slide his tongue to invade the inside of your mouth.

The car window were fogging up from the mixed of your breaths with his, scent of sex wafting in the cramped space. His thrusts were rapid and desperate.

Like he'd been getting chased by the time or simply just trying to chase the release to put some load into you.

"such a good, good girl."

He coos into your mouth, saliva mixed into each other as he gaze into your dazed eyes, your moans drown out into his heavy breaths, hips snapping into the pillow of your ass in each thrusts that make the car wobbling from the force.

Then he's burying himself deep into your womb as he finally spurt out his release. Your head lolled to the side of you whine and whimper, him groaning and kissing the side of your face with frantic affectionate, while his hold on you kept firm and possesive like he cant bear an inch away from you.

"god...that felt so good."

He kept himself there as he felt his cum overflow your inside, slipping out the ring of your entrance. "you're okay, baby?"

One of his hand reaching up to swipe the strands away from your face, pecking at the crown of your head as you nod at him, trying to take a breath.

And when you're done, leaning back to look at him in the face where he got them smitten smile curved out his lips, only to yelp when you bit him on the jaw.

"ouch! What's that for?"

You huff at him. "everything."

Been wanting to do that since he pulled up to some nowhere, empty parking lot after dropping his wife from the airport. Correction, your step-mother.

"you're still mad about it?"

A pout form on your lips, and physically sigh.

"Dad's sorry alright? And she already fled to another country, i've send her to a vacation."

"Not happy bout it."

You're being a brat. And he's more than happy indulge to the antic of you with a little act of huff and puff.

"Come on. you're still my favourite daughter though. my teeny little baby."

He smothered your face with kisses, shifting around loud peck and nibbling at the soft of your cheek, had you scrunching up your face.

"And you still married that woman. Even though im the favourite. Why?"

He stop, pressing his lips into thin line as his eyes swift around the cramped space.

"Well, she's pretty and cute. Aint that enough?"

You bit him with more force on the neck and he physically jump at it.

"I am pretty and cute."

You glare at him, one where you'll be looking like some spicy kitten for attention and love because he'd been neglecting you since he'd gotten married again. That's why he's pulling up to some shady parking lot the second he got the chance.

Dad just puff out a breath, eyes literally smiling at your antic. "Yes, yes you're the most prettiest and cutest daughter i have."

The assault comes once again, devouring the skin of your face in more kisses and nibbles as you absorb all of them.

"want dad to divorce her to show you how much dad love you?"

You blink at him, eyes darkening at the suggestion. "That would be better."

The words were enough to bring some renewed lust and twisted devotion surging into his veins. But dad plays it off with a smirk on his face.

"Alright. dad will. But maybe two or three months more..."

The pout came back into your face, glaring daggers into his eyes. You hop onto his cock, catching his breath away as you grind your ass back and forth.

"Make it fast. I hate to see her face around my home."

Safe to say you've been holding grudge against your step-mother, and dad knew. He always knew, he just like to pull the string and playing around with it.

"scary." He chuckle, clearly are heart-swooned by you as he tighten his grip around your body, hands coming down to squeeze at the cheeks of your ass. "dad really need to stop spoiling you."

He's trying to threaten, but that grin on his face just gave it away as you rolled your eyes at his.

"you're the reason im like this, dad."

"yes, yes, it's all dad fault."

And he's pecking at your lips, exaggerating the 'mwah' as another and another came after each kiss. His cock slipped out from your pussy, making some load leaking out like you cant hold all of him, but that's not his concern because he's still hard and aiming the tip of his cock to the hole of your ass.

"Anal next?"

You click your tongue like you annoyed.

"Cant we do it at home?"

And he look around out the parking lot, empty. "We still havent caught yet. So no worries."

An exasperated sigh coming out your lips. "I dont care about getting caught, dad."

The grin on his face widen. Nudging his nose against yours. "My baby dont like car sex that much?"

His voice were one of tease and playful, and you scrunch your face at him. "Fine, anal and we're back."

That's enough consent he need as he start to poke on your asshole, spreading left cum around the rim. "Wont take long. Just another load and we'll be back." He promise, catching your lips into a more purpose and gentle kiss.

Hands guiding your hips to sink down his cock as he breath into your mouth. Making a mental to-do list to lay you out on the nearest place back at the house after this done.

That 'distraction' had gone, and he had no intend to stop.

Not before you're satisfied and full of his cum at the end of the day.
