Chapter Text
Katsuki cannot sleep. It’s been over an hour since they got under the covers and ever since then the omega has been wide awake. Shouto’s sleeping soundly behind him, an arm wrapped around his middle, resting lightly over his bump and nose stuffed into Katsuki’s nape, snoring softly and quietly into it.
Katsuki sighs, placing his hand over Shouto’s on his stomach. It’s all because of you, he says in his head, stroking the alpha’s fingers which lies on his stomach idly.
The second trimester has definitely raised, certain urges, in him. He’s more sensitive ever since entering the fourth month of pregnancy—physically and emotionally; and horny, so incredibly horny. All. the. damn. time. When Katsuki’s not horny, he’s still horny, and when he is horny, he’s very horny; it’s like a heat that is constantly burning in the pit of his stomach.
Katsuki squirms, playing with Shouto’s fingers and imagining all those times the alpha had them in his hole, stretching it out, curling them just so, making him cum over and over till Katsuki’s legs are shaking like a newborn colt, gushing around his alpha’s fingers. Dirty promises and sweet words of praise whispered into his ear in a low, gravely voice while Shouto rocks into his cunt, reaching in deep, so deep in him—
Fuck. Fuck, fuck, shit!
Katsuki feels himself growing wet in his sleep pants, squeezing his thighs together in a poor attempt to stimulate his clit, surely swollen by now, given how aroused he is.
A small noise of frustration slips out of his mouth because it’s not nearly enough to satisfy him. At this point, nothing but his alpha can truly satiate him.
He whines lowly through his teeth yet again, biting his lower lip when another gush of slick leaks out the more he thinks about stupid Shouto and his stupidly long fingers and his stupidly talented tongue and his stupidly huge dick and how much wants—something, anything to take the burning edge of his arousal off.
His patience wears out after some time and various tries at stimulating himself without waking Shouto up, also because it’s borderline unbearable now. He needs to relieve the ache somehow. Katsuki shifts a bit, getting comfortable, carefully untangling his leg from Shouto’s and spreading them a little under the sheets. Just as he’s about to reach down to touch himself, he hears a groan behind him.
“Katsuki?”
Shouto’s voice is a few octaves lower, still heavy with sleep. It goes straight to Katsuki’s cunt, pools hot in his core.
They sit up and Shouto turns the bedside lamp on before his hand goes to stroke Katsuki’s back while the other finds his bump.
“Baby, are you alright?” Shouto’s voice is laced with concern and Katsuki feels a little guilty to have woken him up like that. He squeezes his thighs slightly to hide the fact that he’s so turned on right now, embarassed because of how needy it makes him appear.
But Shouto’s always been very perceptive, always so quick to latch onto the subtle changes in the surroundings. His senses have become heightened even more now that his omega is carrying, fretting over Katsuki for the smallest of things. As soon as notices that his mate needs something or is in discomfort, Shouto’s on him that instant itself, making sure that all of Katsuki’s needs are tended to.
Shouto scents the air immediately and his breath hitches.
There’s no mistaking it.
His lips quirk up in a smug smile, drowsiness gone the second he realises. “Katsuki, sweetheart, are you horny?”
Katsuki’s entire face flushes, ears reddening, cheeks flaring pink. He’s wide-eyed now, breathing a little laboured as a hint of Shouto’s own smell of arousal reaches his nose.
He bites his lip in mortification.
Shouto’s sitting behind him, chin resting atop his shoulder. Cold fingers skirt under Katsuki’s shirt, stroking over his heated skin. Just a small touch is enough to make Katsuki sigh, melting back in Shouto’s arms.
“Tell me Katsuki, are you? You’re really warm,” Shouto mumbles, nosing along the line of his jaw and making fire lick at his insides.
That fucker. He’s teasing Katsuki. He knows it, he can smell the arousal seeping into the air, can see the way Katsuki’s squirming in his place as slick drips from his hole.
Katsuki looks back at him. Shouto seems more awake now, his eyes already watching the omega keenly. He raises his eyebrows a little, smug grin still on his lips, chuckles at the pleading look in the omega’s eyes, silently telling him—take the damn hint already, you bastard.
Shouto hums and kisses are pressed into Katsuki’s hair, behind his ear as fingers rub the top of his tailbone under his shirt.
“Shouto…” Katsuki whispers into the air, tilting his neck to the side so that Shouto can kiss the flushed skin there too. Shouto lets out an amused chuckle and complies easily, dropping his head to nuzzle in the space between Katsuki’s neck and shoulder, brushing his lips softly on the mating scar there before he starts to place open-mouthed kisses, reaching forward and biting Katsuki’s collarbone.
A sharp gasp tears through the room, Katsuki’s hands flying back to Shouto’s head. He buries his fingers into the soft hair as the alpha sucks on his skin. His clit throbs painfully in his briefs and he feels another drip of slick from his entrance.
Katsuki tentatively reaches down and slips his hand beneath the sheets to feel the dampness seeping through his briefs.
His breath catches in his throat.
“F-fuck, I’m so fucking wet Shouto,” Katsuki murmurs, rubbing his index finger between his folds through the fabric.
Shouto’s chest rumbles pleasantly. He grabs Katsuki’s hand and pulls it out, cooing at the way the omega whines at the loss.
“What’s gotten you so riled up baby? Were you dreaming?” Shouto’s voice has a twinkle of intrigue, fingers caressing the side of Katsuki’s waist.
“N-no,”
“Then, were you touching yourself while I was sleeping?”
Katsuki gapes.
“Wha—fuck no! Why would I be touching myse—” he cuts himself off, because he was reaching to touch himself right before Shouto woke up. Just not in his sleep because he was wide awake and fully aware.
More kisses are pressed into his hair and skin, Katsuki’s head growing light.
“…I don’t know okay? I—I’m just really fuckin’ horny.” he whines in a pitiful voice.
A deep voice cuts through the fuzz in his ears.
“Oh? Maybe it’s because of this?” Shouto taps his fingers lightly against the bump below his stomach, his cheek pressed to Katsuki’s sweaty temple. “You’ve been more sensitive and highly receptive to everything. Always so hungry for me,” Shouto murmurs, voice lilting at the end of the sentence.
Katsuki swallows down the saliva pooling in his mouth.
“Mhmm. I’ll have you to thank for it.” the blond says, scooting further back into Shouto’s warm body. The alpha always sleeps shirtless and Katsuki can feel the heat from his body seep into his even through his t-shirt. It’s nice.
Shouto nods and makes a small quip of approval at that, dips down again to kiss Katsuki’s neck. “Mm, I fucked a baby into you, didn’t I?”
Katsuki’s heart thunders in his ribcage, cheeks flushing pink even more, those words doing nothing but making him throb down there.
“You begged me for my knot, didn’t you sweetheart? You came so hard on my cock that night, thought you were gonna pass out.”
Fuck Shouto and his vulgar mouth. Heat mounts more and more in his body, rushing south and making him positively ache.
Katsuki never really thought of giving birth to pups. He knew as an omega, that was something he should look forward to, that was something that he should be hoping for, someday. But he always put his career before everything else, Shouto being the only exception. After all, he is a hero first, an omega second. Kids would be too troublesome and Katsuki certainly did not want any unwanted distractions.
Also, both Shouto and Katsuki aren’t that great with children. Katsuki finds the brats annoying at most and Shouto does not prefer interacting with them much either. When they’re out rescuing kids, they leave the comforting to the other heroes or medics on field because both of them don’t know how to deal with children. They’re awkward, scary (on Katsuki’s part) and complete amateurs when it comes to handling pups.
A few months back, some kidnappers had nabbed a few kids, wanting to make money off of them. Shouto and Katsuki were assigned the rescue mission and they succeeded in saving the kids. There was a little girl in the kidnapped group who somehow took a liking to Shouto immediately, latching onto him, hugging his neck and nuzzling into him with happy quips.
That was the first time Katsuki had seen Shouto giggle and play with a child, booping her nose, rocking the little pup in his arms until she fell asleep, exhausted from the traumatic situation. It was such an endearing sight.
The next time Katsuki’s heat arrived and was at its peak, as he was drowning in the throes of it—clinging onto his alpha while Shouto was fucking into him, knot catching onto his hole with a wet schlick everytime he drove into him—his fever-addled brain could only conjure up images of that day. The small girl cradled in Shouto’s arms, his mate lovingly holding her and rubbing her back in a soothing manner, crooning at her in a soft voice.
And all too suddenly he wanted to give Shouto pups of his own.
His mate is so strong and caring, always looking out for others, especially his omega. There’s just something about the way Shouto loves him, dotes on him, worships the blonde whenever he can, showering kisses and praising him with words dripping sweet like honey at every chance the alpha gets. Katsuki wanted to give him something in return too, something valuable, precious.
He thought about little ones who looked like a mix of them both running around the house, Shouto laughing along and playing with them, cradling their puppies to sleep.
That was enough to make Katsuki cry and beg Shouto to lose the condom and take him raw, knot him and fuck his seed deep into his body.
Katsuki was expecting a lot of things from the estrogen boost the pregnancy brought, but he hadn’t anticipated the horniness and urges that came along, his sex drive increasing every passing month, especially when he thought about where the baby came from.
Ever since that night a month back when Shouto had bought it up. He was balls-deep in him and had made a teasing comment about how he put a baby in the omega. Katsuki was caught completely off-guard with how much it affected him, his mouth parting on a loud moan and his stomach clenching as he came so hard. Shouto was shocked silent, his eyes widening for a second before his lips lifted in a mischievous smile and he fucked Katsuki well into overstimulation, very much into the kink he just discovered.
Since that night, it had been a blatant indulgence for the alpha. Shouto would whisper filthy sentences about how he knocked the omega up in his ear as he was fucking him, or fingering him, knowing how much Katsuki loves it.
Katsuki never thought that he’d like it so much, being heavy with Shouto’s pup, basking in all the attention his alpha showers him with. Katsuki dare say that he’ll miss it after giving birth. Although, he knows that if he’s okay with it, Shouto has absolutely no problems keeping him pregnant all the time, giving him a fucking litter if he asks for it. The alpha is obsessed with his bump, always wanting to touch it, be near it, kiss it and scent it every hour.
He’s bought back to present time when he feels Shouto’s fingers slide underneath the bump, drumming against his mound before it presses lower to where his slit is leaking profusely.
Shouto groans, “Shit, you really are so wet down here,” he says, dipping his finger in his slit through the fabric. Katsuki’s toes curl in the sheets, hissing when Shouto circles his clit, the friction making his pussy flutter.
“Keep your legs spread, yeah?” his lips are brushing against Katsuki’s pink cheek, the other hand holding his waist tenderly.
Katsuki nods. “Y-yeah, yeah, please, I need it—” his cunt aches now, thick flares of heat spreading throughout his entire body, rocking ever so slightly towards the fingers petting his sex.
“Shh, I got you baby. Just relax,” Shouto’s whispers. Katsuki sighs and goes lax, huddling close to him as his thighs spread wider.
Shouto smiles, kissing his hair. “There you go my love, just like that,” he coos, slipping his hand in Katsuki’s briefs, finally, feeling the coarse hair there before his finger slides down his clit and between in folds. Katsuki moans softly, turning his head so that his nose is pressed against Shouto’s warm neck.
The heat from being under the sheets coupled with the heat radiating from his alpha makes Katsuki sweat in a good way.
Shouto’s fingers are teasing but not cruel, his touch tender but arousing at the same time. He rubs the pad of his index finger against his clit, the nub swollen, before sliding down to his hole again. Shouto can hear how wet Katsuki is, and he isn’t even inside yet. The blond blushes at the sounds coming from below, warmth creeping up in neck even as sweat cools on his skin.
Another digit joins the first, spreading his folds apart, dipping into his entrance and back up, occasionally brushing against his clit. Katsuki breaths go erratic against Shouto’s shoulder, closing his eyes and letting himself feel.
“Good?” the alpha asks, his other hand stroking Katsuki’s back and side, pulling him in closer if that was possible.
“Yeah, so good, oh—” Katsuki moans as Shouto’s middle finger breaches his hole, slipping in with no resistance given how slippery and wet he is.
Shouto hums before he removes his finger and instead goes back to what he was doing previously, running his fingers along the flushed lips, up and down.
“N-no,” Katsuki whines meekly at the loss, squirming and trying to get the finger back into him. His cunt aches with need. “Shouto please, I want—”
“I know, baby, I know,” Shouto croons, kissing the blonde hair and Katsuki’s temple, nosing along his jaw lovingly. The other hand which was stroking his back and side comes up to his chest.
“You feelin’ okay here?” Shouto asks, sneaking his hand underneath the shirt and cupping his tit, circling his nipple gently.
Katsuki bites his lip. His breasts are swollen, in preparation for producing milk for the pup. It’s painful on some days, Shouto knows because he’s helped massage Katsuki’s chest numerous times, soothing away the soreness. But he’s okay now, they’re still tender but not in a bad way.
“Good, yeah, mmm,” Katsuki voices, pushing his chest out subtly, hoping Shouto takes the hint. The alpha does, ever so attentive one when it comes to his omega.
He takes the nipple between his thumb and forefinger and twists it, applying pressure that’s not too much but not enough at the same time. Katsuki whimpers, one hand twisting in the sheets and the other bracing against the outside of Shouto’s thigh.
“I wanna take the pants off, ‘s too fuckin’ hot,” Katsuki complains. Shouto nods, removing his hand from the briefs and tucking his thumbs in the waistband. Katsuki’s lifts his hips and wiggles his way out from him, shivering when the cold air hits his flushed and heated pussy.
They get comfortable again, Katsuki’s back pressed against Shouto’s front. He feels much better already, welcoming the breeze as it cools down his body a bit.
Katsuki takes Shouto’s hand and brings it to his mound the second they’ve settled in, not wanting to be empty for long. Shouto laughs at the neediness, goes back to petting and playing with his omega’s pussy. Katsuki muffles a moan into his mate’s neck when Shouto pinches his clit gently, core pulsing and tightening.
His hand creeps back into Katsuki’s shirt and cups his tit, squeezing, digits gliding up and down his slippery cunt. Katsuki thrusts his hips into Shouto’s hold, trying to get the alpha to fuck him properly, his breath coming out in hot puffs as he kisses Shouto’s neck and shoulder absently, already a little out of it.
Katsuki mewls when Shouto’s finger sinks into him with a wet squelch; the sound seemingly echoing in the quiet bedroom and making Katsuki blush yet again. He squeezes the meat of Shouto’s thigh, opening his legs wider.
“Shouto—mmm, yes…”
“Feels good? Tell me if it’s good baby,” Shouto coaxes, pinching and rolling a nipple with his thumb and forefinger while sliding into Katsuki’s cunt till the last knuckle.
“Oh—it’s so good, it’s perfect—fuck,” Katsuki shuts his eyes at the pressure in his pussy, mouth open and panting into Shouto’s neck.
“More?” Shouto asks, teasingly pressing the pad of his index in alongside the middle finger.
“Yeah, hnnn—”
Shouto hums, sliding both fingers into Katsuki’s slick entrance, pulling out and thrusting back in, shallowly fucking him.
Shouto’s hands take him apart so thoroughly, gentle but rough at the same time, exactly how the blonde likes it. Katsuki feels so hot, the warmth unbearable as beads of sweat begin to roll down his forehead.
“Fuck, you’re so open for me baby. I could just slide inside you right now, look at how wet you are,” Shouto says, voice filled with amazement. He draws his fingers out, strings of slick connecting them to Katsuki’s cunt. “Look.”
Katsuki does, watches as Shouto spreads his fingers, wetness stringing and dripping down the length of his digits. He presses them into his hole and draws them out again, the clear slick stretching out from Shouto’s fingers and back to his cunt again. Katsuki hears the wet squelch even more clearly, hyper aware of everything. He’s half ashamed of how he continues to drip profusely, but he’s mostly just really aroused.
Katsuki keens when Shouto carefully drags his thumb on his clit, fucking in deep with two of his fingers, grinding away at soft walls and probing in.
“Oh, please—like that, hah—”
Shouto pinches Katsuki’s nipple, squeezing his tit. The omega shudders at the sparks tittering up his spine, goosebumps raising on his skin.
“Look at how big you’ve gotten, heavy with my child. Pretty…” his voice is dreamy and full of adoration, the sweet praise whispered into the blonde’s ear as Shouto brings his hand down from Katsuki’s chest to his abdomen to rub the baby bump, possessiveness and love all filled in the way he holds it. It’s gentle, a solid weight on his stomach that’s not too heavy to be uncomfortable but not too light that it’s just a fleeting touch. It’s perfect, a grounding presence that’s a reminder of the precious life growing within him.
Katsuki cannot take it anymore. He wants to melt away in Shouto’s embrace, he wants to be even closer, doesn’t want to let go. He turns his head and raises one hand to cup the back of Shouto’s head, pulling him in for a desperate kiss, licking into his mouth as soon as his lips part. Shouto moans into the kiss, nips at Katsuki’s lips and sucks on it, letting the slow drag of their tongues consume him.
When Shouto’s thumb digs into his clit a little too roughly, Katsuki hisses against Shouto’s lips and pulls on dual coloured locks, shivering at the painful pleasure, gasping for breath because it feels so good.
“So hungry for me, aren’t you?” Shouto murmurs, smirking at the resounding and downright needy whine that reverberates in the room.
Katsuki’s hand drops and instead reaches back to cup Shouto’s dick, almost fully hard and trapped in his boxers. It’s an awkward reach, since he has a big tummy to look out for, but he still manages to reach in and close his fingers around the length, squeezing and stroking how much ever he can.
Shouto’s movements stutter, hissing when Katsuki’s swipes a thumb over the head and under it. “…Katsuki, it’s alright. I’ll take care of it, later okay?”
Katsuki shakes his head, barely suppressing the pitiful noise that falls from his lips. “Let me do this, I want to—please…”
Shouto chuckles and kisses the velvet slope of Katsuki’s cheekbone. “Alright, keep going.”
Katsuki obeys, moaning when Shouto’s fingers press inside his folds again. The alpha dips down and presses his mouth against Katsuki’s skin, muffling a loud groan when the blonde flicks his waist on an upstroke, the glide made easier now that Shouto’s leaking precum.
His breaths are hot against Katsuki’s neck, one hand squeezing the mound of his chest, every pinch and pull making liquid fire lick at Katsuki’s core. He works the fingers deep, quirks them inside and Katsuki stumbles on a whimper, hips lifting to get more of it.
“Harder, Shouto please—!”
“Harder?” Shouto teases, “Like this?” his fingers grind in and he curls them upwards, hitting that spot in Katsuki which makes him see stars, before drawing back out and pushing them in,“Yes, yes, yes—fuck—!,”
Katsuki chokes on a gasp, his fingers squeezing Shouto’s dick as his cunt is fingered fast and rough, wet squelching ringing in his ears over the sound of his own whimpers and mewls of pleasure.
Shouto nibbles at the shell of his ear and licks it, sucking on the lobe. “Such a good boy, my fingers feel good in you, hm?”
Katsuki nods fervently, out of breath.
“Shit, I wanna eat you out, taste your sweet slick, want it dripping down my chin.”
The blonde keens, imaging that sinful tongue curling inside him and he wants that too, he wants everything Shouto’s willing to give him.
“Shouto—!”
“That a yes?” his fingers push in deeper, the pressure on his clit increasing.
“Y-yeah, whatever you want, just please—”
Despite the answer and Shouto’s affirming hum, he doesn’t move. Continues to drive his fingers and fuck Katsuki quicker.
The omega’s whole body feels feverish, skittish and so warm. His pussy clenches around the fingers as he feels the pads of it reach and probe deep in him. Shouto carefully grinds the heel of his palm on his clit and the added stimulation makes him jerk in Shouto’s arms. His breathing is haphazard, toes curling and knees locking as he feels it just around the corner.
“Ah—fuck, mmm…” eyes shut and teeth biting into his own lips, his fist tightening around Shouto’s cock. The alpha curls his fingers and strokes that spot inside him and it has Katsuki’s eyes rolling to the back of his skull. His other hand climbs up to his chest to knead it gently, squeezing and pinching his nipple.
“Right there—oh, right there, don’t stop,”
“Gonna cum for me?”
“Yeah, fuck yeah—” Katsuki gasps. Broken moans and mewls fall out of his mouth as he feels himself teetering right at that edge. Teeth nip at his ear and trail down to his neck and collarbone, a tongue licking the sweat pooled in the crevices of his neck. It’s right there, just a bit more, a little more—
“I’m close, so close, nnggh—” Katsuki’s voice is barely a whisper.
Shouto’s reaches below to cup his baby bump again, “Fuck, you look so good like this,” he rubs the skin lovingly, fingers pressing gently on his belly, right at the centre, “Love seeing you waddle around, tummy round with my pup. So fucking hot.”
Oh heavens, the moon and the stars.
“Shouto…” He squeezes Shouto’s thigh and chokes on a loud moan as he orgasms, eyes shut and cunt clenching tightly around the intrusion.
“Fuck, mmm—shitt—” Shouto rocks his fingers in and out, fucking him through his climax, the pleasure rushing up his body and face, blush on his cheeks. He places soft kisses on Katsuki’s pink cheeks, cooing at how the omega’s pussy shivers and flutters around the digits.
Katsuki slumps back against Shouto, boneless and tired, breathing still a little uneven as he slowly climbs down from his high.
“We aren’t done here yet. I did say I wanna eat you out, didn’t I?”
Katsuki’s eyes widen, and before he can protest, he’s being manhandled onto his back carefully, Shouto wiggling down the length of his body till he’s between his thighs.
Katsuki’s still very disoriented and sluggish from the last orgasm, but moans weakly anyways when Shouto kisses the inside of his thigh, turning his head and pressing his nose to the soaked lips and inhaling deeply.
The omega feels the rumble of a pleased alpha vibrating from his pussy and up his body.
He doesn’t waste any time, dipping down to lick the wetness that coats Katsuki’s inner thighs, sucking and moaning in appreciation at the sweet taste that floods his tongue. The kisses lead to his entrance and Shouto takes a moment to admire how flushed Katsuki’s pussy looks, pink and glistening, clit swollen even after the recent orgasm.
He kisses the hard nub and licks between Katsuki’s folds.
The omega keens and shifts, pushing on to his elbows to see over his bump.
Shouto flicks his tongue in short movements on his clit, salivating at the heavenly taste of his omega’s slick, straight from the source. He continues teasing his tongue between his folds for a while, before taking a deep breath through his nose, dipping lower and sliding his tongue inside Katsuki’s cunt.
He takes his hand and laces their fingers together beside Katsuki’s thigh, giving the blonde something to hold onto. Shouto starts eating him out, tongue lapping at the juices, probing inside and moaning at how the hole opens up for him.
“Nnn—Shouto, keep doing that—hahh,” Katsuki sighs, encouraging the alpha, his legs spreading wider to accommodate the head between his thighs more comfortably.
Shouto whines and hugs his thighs, pulling him in closer as he mouths at Katsuki’s cunt, fucking him with his tongue. His chin is wet with Katsuki’s juices, nose smushed against his mound, all and entirely covered in his omega’s scent.
“Fuck, baby, you taste good,” Shouto murmurs and dives right back in, his tongue laving wet and hot over his clit, between his folds before he thrusts it back into Katsuki’s pussy.
“Shouto—you’re so, so—nnghh—!” Katsuki doesn’t get to finish the sentence, all ten toes curling in pleasure when Shouto sucks on his pussy, eats him out like a man starved. His fingers are wrapped tight around the blonde’s thigh, keeping his legs spread wide.
Katsuki goes cross-eyed when Shouto closes his lips around his clit and sucks—hard. His hands fly out to Shouto’s hair, clutching the strands tight, keeping his face buried into the heat of Katsuki’s mound. The alpha groans and his movements become stronger, flicking the tip of tongue over the sensitive nub.
“Shit—mmfuuuck, right there—feels good—,”
“Yeah? Gonna cum for your alpha again?” Shouto rasps, pulling back a little. Smirking at the pitiful mewl that falls from Katsuki’s mouth.
He lifts his head up and looks at Katsuki through his wet bangs, carnal gaze fixed on him as he drags his tongue over his lips, savouring the taste of the sweet slick of his mate, all while keeping his gaze locked firmly on Katsuki.
Oh.
Oh, Shouto looks fucking gorgeous like this, sweat dripping down his temples, eyes wild and clouded over, cheeks and nose flushed rosy and wet because of his slick. Such a handsome man, and Katsuki gets him all to himself. The thought stokes the possessive fire that curls in his body.
He hopes their pup looks like Shouto.
Katsuki whimpers and nods, wiggling his his hips closer to seek that sinful mouth again. Shouto kisses the sticky skin of his thigh, nipping the flesh there. It makes the omega squirm as he curls his fist into the sheets.
He then kisses his mound, running the tip of his tongue on his clit and over his folds, gently, unlike his earlier pace when he was lapping vigorously at his pussy. This is the alpha toying with him, infuriating how he teases Katsuki with the barely there contact and butterfly kisses.
Katsuki still grows wetter, because even a minimal touch is enough to rile him up with how hypersensitive he is.
“Stop—stop teasing and put your mouth back on me.” Katsuki growls, shivering when Shouto breathes hot over his pussy.
Shouto laughs and does as he’s told. Gets his mouth back on Katsuki’s cunt and delves his tongue right back in, sliding a little deeper than before. The soft walls give so pliantly, hole pulsing around the intrusion. Katsuki has his eyes squeezed shut but he feels more than hears a loud groan that Shouto muffles against him, the vibrations travelling up his body and making him shudder.
Over the wet noises his pussy is making as Shouto eats him out, he hears the unmistakable slap, slap, slap of fingers fisting over a cock.
His opens his eyes and sees the movement of Shouto’s hand. Katsuki knows because he’s watching him jerking off, but he still wants to ask. “Are—ah, are you touching yourself?”
“Mhmm,” Shouto hums between his legs.
Katsuki bites his lip and blushes. He loves whenever Shouto touches himself as he pleasures the omega. It makes him feel all the more turned on, the fact that his alpha is getting off to pleasuring Katsuki, his scent and his taste. It makes him feel wanted.
“‘M so hard, shit, and you taste heavenly.” Shouto mumbles in between licks, moaning every so often.
Katsuki can’t see it but he can picture it vividly, Shouto’s lean fingers wrapped around his own cock, stroking it till its red and beading precum, dripping down the shaft. It makes the blond keen, rolling his hips to meet that tongue.
“Shouto, you—you can cum inside,” he says breathily, “Want your cum in me, mmmplease—,”
Shouto groans loudly at the idea, shutting his eyes. “Katsuki…fuck, fuckk—”
He doubles up his effort and starts lapping at his mate’s pussy more eagerly, grinding his tongue in deep, flicking over the clit. His sole purpose right now is to wring out another orgasm out of Katsuki.
Katsuki can feel it coming again, just ‘round the horizon, insides twisting pleasantly.
“Ah—! Fuck yes, yes, yes—” he chokes out, falling back onto the bed and hooking his leg on Shouto’s shoulder, heel digging harshly into his back. He rocks against that mouth, breathing laboured again. He knows he’s being loud, choked moans and gasps and pleas tumbling out of his mouth before he can stop them. He feels like everything is closing in on him, zeroing at the point of ache between his legs, so much pleasure spreading throughout his body.
“So close, ahh—‘m so close, please—” he moans, mouth lolling open. He feels it approaching so quickly, body pulled taut like a string. He just needs—he needs—
Shouto knows what Katsuki desperately wants right now. And on cue, he opens his mouth and bites at Katsuki’s clit very gently, taking it between his teeth and sucking.
That pleasure bordering on pain is what throws Katsuki off the edge.
Katsuki shouts, his thighs shaking and squeezing around Shouto’s head as he cums, squirts and gushes so much in his mouth, the alpha greedily drinking it all up. Lapping at his cunt, licking and slurping so that nothing goes waste.
“Fuck, fuck, fuuuckk—,”
It’s a lot, the intensity of this orgasm catching up to Katsuki as he instinctively cups his baby bump when his back arches a little off the bed, keeping it safe as he struggles to breath and squirms against the mouth still on him.
He collapses back on the bed, eyes still closed, ears buzzing and chest heaving. His limbs grow heavy and he whines in over sensitivity when the alpha licks his clit tenderly, riding out the orgasm.
Shouto draws back. His fist keeps working over his dick, the movement slow and easy, hissing when he circles the wet head with a thumb, smearing the precum around.
After a couple seconds pass for Katsuki to catch his breath, calming down his thudding heart, he opens his eyes and pushes Shouto with his heel. He looks like a mess, a hot mess. Chin dripping with slick, lips red, face and neck flushed and glistening with perspiration.
The alpha sits up on his haunches. He’s hard, the tip red and leaking so much. Katsuki can smell the musk of the alpha’s arousal under his own scent. He wants to make Shouto feel good too.
“Keep going, don’t stop,” he says, watching with rapt attention at the way Shouto fucks his cock in the tight circle of his hand.
Katsuki maintains his position, keeps his legs spread. Shouto swallows tightly, his gaze slipping feebly from Katsuki’s flushed face, to his bump and then lower down to his dripping pussy. His eyes linger there, bites his lip and squeezes the shaft, grunting lowly.
Katsuki keens in approval. “C’mere,” he whispers, arms open, inviting him in. Shouto goes, balancing his weight on his arms, careful to not put any pressure on Katsuki’s stomach as he dips down at the same time the blonde reaches up, the angle awkward but they make it work.
Katsuki melts into the kiss, sighing and carding his fingers through dual coloured hair. With the other hand he removes Shouto’s hold on his dick and instead replaces it with his own, loving the moan that slips out of Shouto in between the wet kisses.
“Shouto, I want your cum in me.” he says, equal parts demanding and pleading. He flicks his wrist on an upstroke, thumbing the head and dragging his fingers over the hard shaft.
“Shit—okay…” Shouto curses, thrusting his cock in the circle of Katsuki’s hand once, twice, trying to regain his composure. He starts pressing kisses to Katsuki’s neck, sucking a few marks on his skin as he manoeuvres lower, always so careful of the bump. He lifts the omega’s shirt till his tits are out, nipples hardening immediately in response to the cool surrounding.
Shouto latches onto one nipple, suckling on it like a baby. He bites gently on it, licking it after in a soothing manner. Katsuki sighs, pulling Shouto in closer. The alpha does the same to the other nipple too.
“Keep this lifted up, yeah?” he says, gesturing to the t-shirt and sits back on his haunches.
Katsuki nods, shifting so that his ass is practically resting on Shouto’s lap. Once he gets comfortable, he bites his lip and lifts the shirt up till it bunches around his underarms, so that his swollen tits and his bump are out on display. He shivers, half from the cold air hitting his heated skin and half at the way Shouto moans in appreciation.
He looks at Katsuki with hungry eyes raking over his body as he starts fisting his cock again, keeping it near his pussy. “Look at you, fuck—,” he hisses, “knocked up so prettily.”
Katsuki moans softly. He slides in closer, angles his hip in a way so that Shouto can drag his dick between his folds, slicking himself up. “Baby, shit, that feels good.”
Shouto’s breathing is erratic, his face flushed a deep red, all the way down to his neck. Hair sticking to his forehead, his musky scent growing stronger the more aroused he gets, mixing in with Katsuki’s own sweet smell.
Shouto slaps the head of his cock gently against his cunt, the sound it makes lands heavy in Katsuki’s ear, thick and wet.
“Fuck.” Katsuki curses in a low voice.
“You’re still dripping wet and so open for me. You really want me to cum in you that badly?”
Katsuki nods his head in a silent plea.
“Yeah? Just like I did to put a pup in you?” Shouto smirks, jerking his dick faster and faster, grunting through his teeth, the sound echoing in the room.
Katsuki’s heart thuds, his face burning at how much those words affect him and heavens and the moon, he doesn’t think he can handle another orgasm tonight.
“Please, please, please—,” Katsuki chokes, his throat feeling a little tight. He’s so needy for it right now, evident in the way his legs open up wider.
Shouto growls at the desperation in his omega’s voice, his thumb spreading his folds as he holds the tip against Katsuki’s hole.
“More, just—a little deeper…” Katsuki whispers and Shouto obliges easily, pressing only the head of his cock inside his cunt. “Yeah, just like that.”
“Fuck, baby, fuck—I’m gonna cum,” Shouto groans throatily, throwing his head back, shallowly fucking the engorged tip of his cock in and out of Katsuki as he jerks off the shaft that is outside at the same time.
“C’mon baby, give it to me, my alpha...” Katsuki purrs, coaxing and urging as he clenches around the head.
“Katsuki, shit—” Shouto moans brokenly, cumming hard inside the warm cunt, coating the walls with his seed.
The omega shudders underneath him, his insides pulsing with heat, making his toes curl and his breathing a little fast.
Shouto pulls out gingerly, watching in fascination as cum dribbles out of Katsuki’s hole and down the curve of his ass. The omega bites his tongue, blushing at how wet he feels down there. Shouto’s breathing heavily above him, jerking off the last bits of cum and smearing it on Katsuki’s swollen folds.
Katsuki reaches down and eases two fingers in himself, pushing the cum that’s dripped down back inside, pulling his fingers out to gather whatever dripped out of his pussy and pushing it back inside too, right where it belongs—in his cunt, warm and thick. He feels good, being claimed like this, no amount of scenting or hickies compares to his alpha’s seed in him, although those certainly are a plus point.
“Christ—that’s so hot, holy shit,” Shouto pants, “You’re perfect,” he leans down, nuzzling the baby bump with his cheek, kissing it on the sides and right in the centre. Shouto’s chest rumbles in a resounding purr, nosing and mouthing Katsuki’s stomach, covering the area with his scent, almost like he’s staking his claim. As if people don’t already know that Shouto’s the one who put a baby in him.
The omega buries his fingers in Shouto’s hair, playing with the damp red and white strands, pulling it back to reveal Shouto’s forehead. He watches the man sprinkle delicate kisses wherever his lips can reach. It makes the blond chuckle at how much of a child Shouto himself is.
“Mmm, you’re such an alpha, god,” Katsuki shakes his head fondly, scratching Shouto’s scalp with blunt nails. The purr grows louder in volume, Shouto’s eyes fluttering shut at the blissful feeling. He lets Katsuki comb through his locks for a while, both of them relaxing so that their heartbeats slow down to normal again. Then, Shouto takes the hand on his head and brings it to his lips, kissing the palm in the middle.
“I love you. Can’t believe I get to have such a lovely omega all to myself.”
“Likewise baby. I love you and your handsome face and how well you treat me and your stupid possessive alpha tendencies too.” Katsuki chuckles.
He’s rarely so soft and mellow, those successive orgasms might’ve made him this way but all he wants to do right now is to praise Shouto, roll around in his embrace and his delicious alpha scent.
Shouto beams up at him, heterochromatic eyes twinkling. “You deserve it babe. After all, you’re giving me such a precious gift, it doesn’t compare to anything in the world.”
Katsuki’s chest surges with so much affection, heartbeat quickening and face growing hot. His eyes almost well up with tears. Damn pregnancy hormones, making him so emotional and shit.
“Idiot. Come here, I want a kiss,” he’s definitely not pouting as he says that but Shouto’s answering coo and ‘aw don’t pout baby of course I’ll give you a kiss’ says otherwise.
He gets his kiss, many kisses in fact, all over his face, his cheeks, nose, eyes, forehead, and lips. Relaxing into the slow drag of their tongues, the sharp nip of Shouto’s fangs. Katsuki sighs, he’s so drained and tired that he can do nothing but lay there and be kissed thoroughly.
It’s perfect. He’s happy right here, wrapped up in his alpha’s arms, their child growing inside his belly.
“You need a bath? Should I draw one?”
“Yeah. A warm bath sounds nice.” Shouto nods and leaves with one last lingering kiss on Katsuki’s lips and forehead.
Katsuki hears the tap running and he sighs, rubbing his bump in post-orgasmic haze. It’s going to be a long pregnancy, but he basks in it, looking forward to the next exciting months.
