Work Text:
Maybe it was the way you babbled at that chunky baby at the 7/11.
Maybe it was when you almost cried at the miniature shoes in the kid’s section of Louboutin.
Maybe it was how little Yuji was glued to your hip when you both visited Jin’s earlier today for the toddler’s third birthday.
Whatever it was… Sukuna was fucking hot over it.
…
Behind you, he leaned against the doorway of the bathroom, watching with a simmering dragon’s glare as you absentmindedly brushed your teeth.
You were dressed in your typical pajamas: one of his white wife-beaters that shrunk tiny in the dryer, and his rattiest pair of red boxers, rolled up at the waistband.
In every way, you were his.
You’d been living under his roof now for a year and some change—cooking for him when he came home tired from target practice, choosing decor for him when he couldn’t or didn’t feel like deciding, answering his pedestrian phone as the lady of the house…
...Taking his cum wherever and however he wanted to give it to you…
Fuck…you were so good for him.
Good—to him…
Despite the uncertain and chaotic nature of his line of work, you stuck beside him, and carried yourself as his other half—near flawlessly.
Of course he wanted to tie the knot. You were already functionally married. And you accepted him for everything he was, including his most unsavory aspects.
But you weren’t in a rush. Still young and sexy, both of you enjoyed your time out being wild, having fun and spending his bloody riches on nonsense when he wasn’t busy with a ‘job’ to do.
You had found a rhythm together.
But even with the crazy parties you’d throw and attend, your daily life was starting to feel—domestic.
You started doing more down-to-earth things together. Homemade Sunday brunches and dinners…weekly face masks and binges of trash tv…having a dry-cleaning schedule to replace the sheets you always messed up…
Sukuna’s penthouse started feeling more like a nest…warmer—cozier…with you around.
And this far into it with you, he didn't want any other brat.
…
His hands were fidgety. One crossed over his abdomen, the other at his mouth, thumb gently scratching at his lower lip…where you liked to bite the most…
And you, in his tight little tank top—looked so fucking ripe. Ready. Perfect for him.
Your engagement ring was waiting in his big gun safe, on standby for the right time, but Sukuna wanted to sink his teeth in and stake his ultimate claim on you—now.
You belonged to this man in every way…except the most permanent one.
And so, suave as ever, he stalked up behind you and pulled you into him, hands on your tummy.
He didn’t say anything, he just held you. Let you feel him.
You smiled around your toothbrush and leaned back into his warm chest. Pressed your ass back against the familiar tent of his sweatpants, and swayed back and forth with him as your eyes closed in contentment.
After leaning forward to spit and rinse your mouth out, you met his eyes in the mirror. Sukuna’s look was…different. He was usually a smiley, teasing terror when he moved to seduce you.
In this moment, he looked…pensive.
“Y‘okay?” You set your toothbrush down and reached one hand up to stroke his face.
He tilted his head into your touch, blinked, and his palms trailed up to your breasts. He wasn’t trying to turn you on with usual pinches or rubs.
He was just—holding them…appraising them...
Checking to see if they were tender or swollen. Feeling their weight, and wondering how much bigger they’d get with his seed growing inside of you... Wondering if your nipples would strain and poke through his tank tops more than they already do…
Fantasizing about milk stains…
Before too much confusion set in on your brow, he caressed you properly, and rolled your perky buds between his thumbs and fingers, sending jolts of pleasure straight down to your clit.
And your confusion melted into arousal.
“Mmmh, Babe…” you sighed, and closed your eyes again, standing on your toes and giving him your weight. He was moving unusually slowly… “Sukuna, what’s up with you?”
“Nothing.”
“Why so slow?”
He shrugged. “Wanna go slow.”
“O-Oh…I like slow…” you purred.
“I know y‘do. Come,” he said lowly into your ear as he guided you backwards, out of the bathroom and to your shared bed. He sat down, holding your sides, still stood between his knees.
You turned around in his hold and looked at him, hands resting at the back of his neck, trying to parse the thoughts behind his gaze.
“You tired?”
“No. Just lookin‘ at ya’.” He was still deadpanning.
You played coy, giving a dimpled smile and swiping your hair over your shoulder with a tantalizing dramatic toss…shimmying your shoulders, sticking your tits out at him…trying to make him crack.
He let out a little huff of a laugh, and broke eye contact for a split moment, trying not to show the hint of pink creeping up on his cheeks. He really hoped your first baby would have your smile…
Before you got too cocky, his restless fingers played around with the tank’s hemline at your waist.
“You take your pill, today?”
!!
“No, shit… Thanks for reminding me.”
You couldn't back away, really, with the way his digits quickly dug into your flesh.
“Don’t.”
“…?”
He gingerly pulled you closer to him, looking up at you, chin resting on your sternum between your breasts, “You want my kids…right?” Like a boa constrictor, his hands wound around your middle…under the tank top, holding you tighter…
There was a tense moment of silent eye contact, and it would have made him nervous, but he felt the vibration of your heart skipping a beat against his chin.
He saw that glimmer in your eye, and then, he finally smiled.
!
“Sukuna-sama…this is serious… Are you being serious?”
He slipped his head under your tank, stretching it over the back of his neck to kiss at your stomach and ribs. “Want you full of me…can’t wait…” he murmured hotly against your skin, “Take this off…”
He gave you the command, but he did it himself. With a hook of his thumbs under the hem, the white cotton was peeled from your body like a string cheese wrapper and quickly tossed to the side.
Your tits…those beautiful tits, were in his mouth before you could even blink. He was so thorough, fondling one and sucking on the other, enjoying how soft and supple you were.
When you started panting and sighing, curling your nails along his scalp, he moved for the kill. “Mm-gonna make you feel good, baby… C’m’ere…”
With a gentle spin, he lay you down on the bed, and pulled your ass to the edge. He was handling you so delicately, shimmying his boxers off of you, caressing your calves as he spread them open for him…
He knelt down, settling his grip on your open thighs and gazing at his little honey pot… “So fuckin’ sexy, baby…”
And he tongued you. Immediately getting high on your scent, wetting you up, nice and slick. Indulging you, he latched his lips around your clit, and teased his thick middle finger around your entrance as he sucked. His long, muscled arm reached up around your thigh so he could palm your breast, massaging and squeezing… He started flicking his tongue ring against your bundle of nerves faster…faster…waiting…waiting———!
As that first orgasm hit you, he slid his finger in and pumped it, adding to the pressure bursting between your hips.
Your thighs clamped around his ears, and you sang for him~!
Spine arching off the bed, toes curling at his tattooed shoulders, you came hard for your man. He growled into you like he always does, so pleased with his baby.
At a brisk hook and repeated pull of his finger inside, you yelped, “S-Sukuna~!~! Too much! ’S too much!!” Your nails tore into the sheets, head tossing back and forth, hips squirming in his hold. “Ah—Ahh—!”
He looked up at you and chuckled darkly, giving himself just a few more seconds of your overwhelm before relenting.
Sukuna would never get tired of that…
…
Except for right now.
He was tryna' knock you up.
Sukuna stepped out of his sweatpants and stood tall, with a wide, commanding stance at the edge of the bed. He was licking his lips clean, smacking at your mouthwatering tang. He looked over you—a king surveying his beloved territory, trailing his hands over your soft hills and valleys…
Your body lit up with gooseflesh, so responsive to him. He was making you sweat already...
“You love me, baby?” he tapped his hard cock against your clit, making you shudder through those aftershocks. His other hand kneaded at your thigh.
“Yes, ’Kuna…”
“You want this forever?” Another tap of his tip, and a rub, smearing his pre all over your slicked up labia…
“Mmmmh~ Yes, Sukuna-sama…”
The fact that you were willing to risk a baby by him without a ring… That—drove him insane. He took a hot moment to bask in his adoration for you, taking a reverent breath, teasing you with the cock you’d give it all for…running his other fingers over tits and feeling your heart, beating just for him…
You put your hand on top of his, and curled your fingers around one of his, smiling up at him, already blissed out...
Fuck, he loved you so much…
He grinned, “That’s good.”
And he slid inside of you, slowly—inch—by—inch—by—delicious, girthy...inch———!
...You hissed at the stretch, and he pulled out a little when he met the resistance of your tight squeeze, then back in again, slooowwwllly, all the way to the root—!
“Oh~!”
“Y' feel that?” He grunted, poking his hot tip at your cervix, shallowly rocking his hips into you. “I want my cum right there… All of it… All the time…”
“Sukuna…”
“So much…wanna give you a belly...” Sukuna smoothed his hand over his tip, poking up below your belly button, under your skin... His eyes were glazed over, fixated...
And then they met yours.
“Y’want that?” he asked with a lopsided grin, his baritone low, quiet... His hips were still gently rocking...
You nodded, panting, clenching and writhing below him, desperate for proper movement—!
But he kept making you wait, holding your legs open and leaning forward, pressing his stomach’s tattooed mouth into you and cementing you to the bed, still rocking you lazily...slowly...
You whimpered and tossed your head to the side, flustered by his pressure on you~!
Sukuna pulled your chin back to him with his index finger, then held your face there, gently pinching your chin and murmuring on your lips, “Tell me whatcha want, baby…”
"Wan' you..."
“Want me t‘ what?”
"You...all of you... Give it t’me…"
"Everything?"
You nodded.
And Sukuna kissed you.
A sigh of heat and need into his mouth, then he started to move.
He was keeping you still, holding you close, one hand settling at the crown of your head to prevent you from jolting up the bed at his thrusting. He kept it consistent, nice and easy, building it up for you…
“Mmmmh~! Mmmh~! God…”
He was going slow and soft enough that you could fuck him back, undulating your hips and meeting him halfway.
Your eagerness charmed him oh so much, and he let you take the reins for a bit, “You take me like a goddess… S’perfect… Keep goin’, baby…”
He watched you work, flexing his thighs and keeping still for you as he let you indulge. When it came to sex with Sukuna, he’d normally be in the driver’s seat from start to finish, but when he had you hot and horny under him like this…he couldn’t resist…
“You love this dick, don’t ya’, baby?”
“Yes, ‘Kuna…can’t get enough…You fuck me every day and it’s never enough…”
He smirked and thought to himself, ‘That’s because I haven’t truly fucked you, yet…’
…
Being on birth control had dampened your senses… You always enjoyed yourself, but the ultimate satisfaction only came with the risk…
Sukuna knew it.
He remembered when you first started dating, using condoms—you weren’t on the pill. It was different. You…were different… More feral…
You got higher on his scent, on his cock, on his cum…
…Sukuna missed that.
You had to switch to the pill because every condom you tried kept ripping around his throbbing curve.
Sukuna was ready to say fuck it all.
He wanted you raw.
Really raw…
…Especially if it would make you his hot mama…
Sukuna could feel you slowing down, trembling, close to cumming, but already worn out…
You had a long day—meal prepping, leg day at the gym with him, helping him spot clean his guns, choosing a gift for Yuji…
Then playing with said toddler for hours at his little party…
He caressed your forehead with his thumb, checking in, “You tired, mama?”
!!
He had never called you that out loud before…
It made you stop your now pathetic gyrating and drop your hips back down to the bed.
Sukuna was waiting and ready to pick ‘em back up for you.
“Y’r gonna be such a pretty mama…lemme get you there…”
This soft side of him was so rare…
“Sukuna-sama…”
“Want you to carry all my kids…as many as you want…” he was holding your gaze, picking up the pace where you left off, speeding up and thrusting harder, just enough to make you whine more…
Your heart was gonna burst. Your eyes were brimming with tears. “‘Kuna, you’re serious?”
“Mmm-hmm…dead serious…” He pecked your lips, relishing in the view of your eyes rolling back for him.
“Fuck, I’m so close… so close, babe!!!” you squeaked.
He smiled, gently grabbing your face, “Open up,” he said, and spat between your wet, waiting lips. Then he kissed you as deeply as his cock was reaching inside you… Hard and deep… Making you cum so fucking hard—you started to cry—!
You cried, and he laughed.
Fat tears streaming down your cheeks, wetting the sheets and your hair… Happy tears, tears of overwhelm…
Sukuna kept fuckin’ you deep, though… Never pulling out too far… Snarling and grunting heavily in your mouth, and when he needed air, in your ear…
You started growling back on his tongue like a little cat in heat from how good it felt, threading your nails into his hair and pulling as he fucked you through that crashing wave of pleasure.
He broke the kiss, sensing your clenching cunt and teetering hips needing more… “Y’need it harder, don’t ya baby?”
“Y-y-yes, S-sir, ple-e-ease…”
He growled, his cock throbbing at your fucked out voice… “Hang tight, ’m flippin’ ya’…”
You both sounded like animals, and he wanted to fuck you like one…
Manhandling you into all fours, staying inside of you, he craned his neck around yours, keeping his lips on your neck, pulling your hair, keeping your spine dipped for him as he fucked you hard…
“Yes~! Yes… Fuckfuckffffffffuck~!~!” You braced on your forearms and fucked him back, hips fluidly meeting his…
“That’s right mama… Take this dick… It’s yours…”
———!
“‘Kunaaaa~!”
Your cunt fluttering around on his curve at this angle had his toes curling into the carpet~!
“Pussy’s so good, baby… So good…fuck… ’M gonna bust so fuckin’ hard inside ya’…”
“Yesss, Sukuna-sama~!”
When you couldn’t hold yourself up anymore, he let your top half melt into the bed, and handled business behind you. He re-adjusted his stance, and yanked your hips higher to fully meet his cock. He was kind of rough with your legs, hooking one thigh up as a handle and pressing you forward so he could get deeper inside you, pummeling your spot, and smushing teasingly against your cervix.
“You’re not leaving this bed…‘til I knock you up… Y’hear me?” he panted.
“Mhmmmm~! O-oh, Godddyessss!-!-!” you agreed, breath and heated moans tumbling heavily from your mouth.
His other hand found your tit—a nice, loving squeeze, compared to his brutal pace… “Gonna get you pregnant, make ya’ my little cow…so I can milk ya’ all day…”
!!
You came again—so loudly—that he had to cover your mouth so the whole city didn’t think he was slaughtering anything but that pussy.
Sukuna felt like he was losing his mind—he was inwardly hissing, out of breath at his fantasies, he started talking crazy, spoiling his plans to propose to you—!
“‘M gonna give ya' this baby, then give ya' that ring… Mmmmh—shit—then we can get out of the city… I’ll take ya‘ to the countryside, buy our own land and a private cottage…so I can keep ya’ safe… ‘n’ fill this pussy up, all day ’n’ night, and hear you scream my name… Hhhfuck...Want it to echo off the mountainside…”
You were crying before—you were sobbing, now.
And when he came, loud and rough, his strong hips glued to the squish of your ass and rutting firmly—you both saw white.
With how much his throbbing nuts pumped out, Sukuna was the one messing up the sheets, this time…
With a grunt and sigh of relief, he collapsed on top of you, and for a long while, you were both speechless.
…
Somehow, some way, Sukuna flipped you back over under his weight, and settled on top of you again, gently pulling his still leaking cock from inside your throbbing cunt. With your breast as his pillow, he felt around between your thighs and fingered his scalding hot cum back inside you, and lightly laughed, closing his eyes.
Perfectly—satisfied.
…
You were, too…and in a daze…
He completely caught you off guard.
…
“Sukuna…?”
“Mmm.”
“I have a question.”
“Hmm?”
“…How did you know I wanted a baby this badly?”
At that, he opened one eye, and grumbled out, “You shoulda’ seen yourself with lil’ Yuji today.” He looked up at you, his cheeky grin still squished against your breast.
You blushed and covered your face, whimpering at his thick fingers still playing around inside you. “…Am I that obvious?”
“Yeah. …I thought it was funny, until that fever of yours became contagious... I can’t stop thinkin‘ about you pregnant for me…” He was vulnerable. He withdrew his fingers from you and splayed his hand on your stomach, caressing you…drawing little shapes...
A beat.
Some tender eye contact.
There were stars in his eyes.
You stroked his cheek, swimming in his gaze. “You’re ready to be a daddy?”
“…As long as you’re the mama,” he kissed your palm, and then shifted up on top of you to kiss your lips.
“You’re gonna be such a dilf…” you whispered slowly on his tongue, still in delirium…
Sukuna chuckled, and caught your lips again.
