Work Text:
It started with Izuku asking Aizawa to help him through his heat.
They had been dancing around each other for a while, ever since Izuku started teaching at UA; he had thought Aizawa would be the one to suggest anything, but Izuku didn’t have the time to dawdle any longer.
So he had just come out and said it, albeit while red as a tomato.
Aizawa had sagged in relief after.
“Yes, I will.” He made a cute little questioning face, and Izuku’s heart squeezed in his chest.
“Does this mean we’re dating now?" Aizawa asked. "I’ve helped people during heats and ruts before, but that was all platonic. I've never really, dated, and I wasn't sure how to ask you out... people keep telling me to be more subtle. I just don’t know how to date...”
Izuku gave a light laugh, nerves leaving him all at once. “You don’t need to be subtle with me. I like you, all of you, and bluntness is a part of who you are. If you'll have me, I'd love for us to be dating!”
Aizawa had really, really taken that advice to heart.
Two weeks into seeing each other, a few days after Izuku’s heat, they were on his bed in his teachers dorm (the teachers dorms were all basically apartments), buddy reading in silence. Aizawa had finished his chapter, set his book aside, and started watching Izuku with intent eyes.
“I want to bottom.”
Izuku nearly fell off the bed, his face turning a bright red. “Wh-what?”
Aizawa’s gaze was as intense as always, impassive and almost looking bored, with the faintest hint of amusement at Izuku’s reaction. “I want you to fuck me.”
Izuku blushed deeper, if that was even possible. “But I’m an omega.”
“You have a dick, i would know. I don’t see what the problem is.” Aizawa teased, trying to look confused.
Izuku stuttered out a reply. “There’s no p-problem! I just… are you sure?”
Aizawa nodded. “You seemed to really like it, so I tried fingering myself two nights ago. It felt good.” he bluntly answered
Izuku twisted his fists in the sheets, nostrils flaring, he almost regretted his earlier advice. Aizawa is so blunt.
“O-okay, now?” Aizawa nodded again, and Izuku reached into the drawer he keeps all his heat supplies in, pulling out a mostly full bottle of lubricant and a condom.
He was so caught off guard and embarrassed he barely knew what to do with himself, but at the same time, the sight of Aizawa unzipping his tight black jeans, coming up flushed and hard, was enough to make him rub his thighs together in arousal.
He had never thought of anything like this before, but now that Aizawa had said it, he wanted it, badly.
It was really good. Izuku hadn’t been expecting to like it so much, but his own pleasure was heightened by how much Aizawa seemed to enjoy himself.
He reacted in ways he never did when he topped, and Izuku drank up every single expression, moan, whine, and jolt of pleasure with fervor.
He actually ended up liking it more than bottoming. Vaguely, he had wondered if that made him a defective omega. He couldn't really bring himself to care too much, though, when the result is so beautiful.
The next move forward was more than a month later. They’d grown much closer, calling each other by their first names and ending conversations with “I love you”s.
They’d also begun to switch pretty regularly. Izuku was relatively certain that if Shouta didn’t require so much more preparation to bottom than he did, Izuku would rarely ever get the chance to do so himself.
It’s another one of those nights where Shouta wants to bottom, and Izuku was reaching into the drawer to procure the regular supplies when Shouta grabs his wrist.
“Actually,” He leans over, grabbing a knotting condom instead, and the knot simulator he wears at the base of his dick during Izuku’s heats. “Do you mind wearing these?"
“Um, no. I-I don’t mind.” he tentatively answers.
Izuku glances over Shouta’s body, laying nude on his bed, flushed and hard yet again. A thrill runs down his spine. “Are you sure? W-will it even fit?”
Shouta nods. “You’re big for an omega, they’ll fit you.”
Izuku blushes. “I meant more along the lines of, um, if it will fit in you.” he clarified.
Since betas didn't produce slick like omegas, Shouta already needed a lot of prep for him, so he assumed this might (would) hurt the man.
He nods again. “It’ll be fine,” he assured.
Izuku acquiesces and happily fucks Shouta on his fingers, nearly forgetting about the deflated artificial knot and condom as he gets lost in the rare physical reactions from his partner.
That is, until Shouta whines and grabs his shoulder before he says “I’m ready.”
He anxiously rolls both the knot and condom on.
Soon he's driving Shouta onto the edge, fucking him as hard as he can until he starts panting and chanting,
“Knot me, knot me, knot me, izu, please, p-please knot me,” in a shrill, needy beg.
Izuku scrambles to inflate the knot. He knows from experience that the hydraulic technology makes it just the wrong side of realistic
But it’s good enough for Shouta, apparently, as when Izuku drives the knot all the way in and finishes inflating it, Shouta comes in messy stripes all over his belly.
Izuku pants with the effort he had just expended. Grinding his cock into Shouta, painfully turned on but unable to come.
The artificial knot is useful during heats, which betas need extra stamina for, but now it’s just inconvenient; pressing in on the base of his dick, making it impossible to come.
Omegas already have a hard enough time coming without anything inside them, this extra factor makes it completely impossible for him.
Izuku whines, grabbing Shouta’s inner knee and pressing it further down on him until it was almost on the debauched man's chest, bending him nearly in half as he frustratedly chases any sensation he could get.
Shouta, from his spot sprawled out below him, gasps, throwing his head back and moaning. “Do you- can you?”
Izuku shakes his head, inferring that Shouta is asking if he can come like this.
“S’okay. You can take it out,” he assures, still moaning from the stimulation.
Izuku nearly sobs with relief, barely remembering to manually deflate the knot so he can slide out of Shouta without hurting him.
He removes it and the condom and crawls forward on his knees until he’s hovering over Shouta’s hips, fervently stroking himself.
Shouta reaches around and slides two fingers easily into Izuku, where he’s slick and empty. The first brush of his fingers over Izuku’s prostate has him coming so hard he wonders how doesn’t hit Shouta’s chin.
So he and Shouta had both enjoyed their first time with Izuku wearing the artificial knot.
The only problem is it was incredibly hard for Izuku to come, what with the constriction of the knot around the base of his dick.
He spins himself on the Miruko themed desk chair in his apartment office, trying to strategize for a potential repeat, thinking of how to make it better.
His eyes land on his laptop, and he sighs, cracking his knuckles.
He’ll just have to do some research. It won’t be the first time he conducts some more questionable google searches on behalf of his partner, he’s just going to have to slog through some iffy pornography and poorly written articles. For Shouta.
He conducts a few variations of “omega knot” searches, but all the results are about alphas knotting omegas, and he huffs in frustration.
He should have known better.
He tries some variations of “omega simulated knot” and finds a lot of results along the lines of toys for omega heats. He tries “omega topping beta” and finds a whole lot of porn, which is, in fact, the exact opposite way around.
He groans, leaning back in his chair. If he wants to do this, he might have to fudge it a bit. He figures it will be more common for omegas to want to knot other omegas, so he tries “omega omega sex”.
Again, he finds quite a bit of porn, and he almost leaves for a new search in frustration, when his eyes fall onto a promising looking link.
"How Alphas or Omegas Can Switch Second Gender Characteristics."
He’s a bit skeptical, but he’s also a bit desperate, so he clicks the link.
“Gland biting has many functions in our society: our bonding scent glands to signify a bonded (for life) pair, our scent glands are bitten by the pack leader to signify your pack and to feel other pack mates high emotions.
Another one of these scent glad biting processes is colloquially known as “bitching”.
This process allows some alphas or omegas to temporarily switch some aspects of their secondary sex characteristics.
If, while aroused, an omega with a penis bites down on the scent gland on the back of their partner’s neck, there is a large chance they will become able to knot, and their chance of impregnating their partner will increase."
It specified the back of the neck, to try and insure couples not ready wouldn't be accidentally bonding while trying bitching, Izuku realised. He'd have to be careful about that.
"Similarly, if an alpha’s scent gland is bitten down upon during arousal: it makes it much easier for their bodies to accept a knot, they can produce slick, and it increases the chances of pregnancy for alphas with wombs.
It is theorized that these processes are a kind of biological failsafe, in case of omega/omega or alpha/alpha pairings.
Certainly, it makes heats and ruts easier for these kinds of pairs, and increases the chance of reproduction in pairs that could already reproduce.
That is to say, while there are vestigial prostate (slick) glands in most alphas and knots in some omegas, the same cannot be said of wombs and penises.”
Izuku taps his pen against his chin in contemplation. This is all very interesting stuff. He’s never heard about anything like this before, but it makes sense that there might not be a whole lot of information, given how rare same secondary gendered couples are.
Plus, there are quite a few citations at the end of the article, which leaves Izuku feeling hopeful about the legitimacy of the information.
It hadn’t said anything about omega/beta pairs. He wonders if he would be able to knot if he did this to Aizawa.
Well, there's only one way to find out.
Aizawa sighs, putting his book down before he turns to Izuku.
“What is it?” he deadpans.
“Nothing!” It’s pulled out of him on instinct, because he has no clue how to bring this up, regardless of the fact that he’s pretty sure Aizawa will want it.
“Your face is currently indistinguishable from a tomato, and you’re kind of vibrating so hard you’re shaking the bed.”
He blushes deeper and sighs, then places his own book aside, and grabs Aizawa’s cold hand, placing it against his cheek. He exhales in relief at the sensation, nuzzling into the hand.
“What is it, Izuku?” The question is gentler this time, fond.
Izuku coughs a bit, still embarrassed. “I want to… uh, I want to try bitching you.”
He winces at the way it sounds, feeling his cheek grow hotter against Aizawa’s hand, which had stilled.
He forces himself to look up and see the expression on Aizawa’s face.
His head is cocked to the side, and he seems more curious than offended. Izuku sighs in relief.
“I might be able to, um, actually knot. If I bite your neck.” He raises his hand to behind his lover's neck, tracing the scent gland in question, feeling Aizawa shiver and lean into his touch.
When Izuku’s voice comes out next, it’s less hesitant, but lower, and rougher.
“The scent from the gland here, when bitten into, might be able to trigger a knot from me. As far as I can tell it’s only been done in omega/omega pairs but… it might work.”
Shouta’s dark obsidian eyes settle on him with a spark in them at the thought of actually being knotted by Izuku, and for a moment Izuku forgets how to breathe.
“I want to try.”
Izuku shivers a bit, removing Shouta’s hand from his face and clasping it in his instead. “Are you sure?”
Shouta nods, leaning in to capture Izuku’s mouth in a kiss. When they pull apart, he rests their heads together and they breathe each other’s air for a moment.
Izuku palms the front of Shouta’s pants and finds him almost fully hard. Deciding they might as well try it now, instead of dragging out the hope if Izuku can't knot from bitching Shouta.
He smiles gently, tugging his shirt off, leaning back to allow Shouta’s hungry gaze to roam its way over his bare chest.
It had taken some coaxing to get him comfortable with his lover’s heated eyes, but now he takes it in stride, since he knows just how much Shouta likes his strong muscular chest.
“Take your shirt off.”
As Shouta starts throwing off his black V neck in almost hidden excitement, Izuku leans over to grab a condom from the drawer.
“No.” Shouta says, tossing his shirt to the side.
Izuku cocks his head questioningly.
“If you can knot and come inside me, I want to feel it.” he pleads. It sounds like an indifferent toned demand, but Izuku hears the request in his boyfriends voice.
Shouta really isn’t afraid to speak his mind. Like, at all. Izuku’s face practically explodes into a blush.
“I-okay.”
Izuku just grabs the lube, then sits back on his haunches and watches as Shouta rids himself of his pink sweats and tight black boxers, cock already hard in anticipation.
Shouta strokes himself lazily, unabashedly, and Izuku can’t help but lean in to kiss him, hands resting on his beta's cheek.
He’s getting turned on himself, aching for contact. He shuffles forward, pressing their chests together and deepening the kiss until Shouta drops his grip on his cock with a breathy gasp.
Izuku can’t help but smile into the kiss at the reaction, trailing his hands down from Shouta’s handsome face to his neck, down his chest, his stomach, before reaching around to grab a firm handful of each ass cheek.
“Yes.” Shouta gasps. “Finger me.” he begs
Izuku blindly paws behind him for the lube, prolonging their deep kiss until he finds it and has to break off to coat his fingers.
Shouta flops back on the bed and grabs a pillow, propping his hips up. He stretches his arms above his head, rolling his wrists, clearly working out whatever tension he had gathered during their summarily interrupted evening reading together.
His dick stands proud.
Izuku smiles fondly at him, barely suppressing a laugh at the sight of a large cat tattoo just above his left hip. The cute pure black cat, with the only drop of colour being blood red eyes, reminded Izuku of the man below him, despite it being in memory of his second oldest cat, Bastard, dying when he was twenty.
Shouta grabs the head board, pretending he was handcuffed like he and Izuku liked to do to him with the handcuffs he owned, and smirks up at Izuku.
“Come on.” He hooks an ankle behind Izuku, reeling him in a bit closer.
Izuku does laugh then. Just a small huff as he smooths one hand up Shouta’s thigh, bringing the index finger of his other to trail circles around Shouta’s entrance.
A shudder racks Shouta’s body, and he tightens his mock-binded hands grip, his legs parting further.
“Zuku, please-” he cuts off in a gasp as Izuku scratches nails down Shouta’s thigh, simultaneously pressing forward with the finger of the other hand.
Shouta isn’t very expressive usually, but Izuku loves pulling reactions and expressions from the stoic man. He can read the subtle hints in the way he holds himself, how he tries to stop the clenching of his hole, the flush on his face, the twitch in his brow.
Izuku presses his hand to Shouta’s inner thigh, pushing up and forcing his legs further apart.
He revels in the way Shouta’s leg twitches, testing his grip, heat in his gaze doubles when he feels how strong it is.
He presses a kiss into Shouta’s inner thigh, and another finger into his ass, gently fucking them deeper into him. Shouta moans, hiding his face best he can.
"ah~ izuku~" he mumbles quietly over and over.
The knuckles of Izuku’s ring finger gently rub against Shouta’s rim as he fingers him, and he has to restrain himself from just shoving it inside along with the other two.
Instead, he bites Shouta’s thigh, locating and rubbing the pads of his fingers against his prostate as he slips a third in.
There’s a loud, almost startled moan, then a slap as he covers his mouth with his hand. Izuku growls against the man's thigh, removing a finger in warning. Shouta moves his hands back to their mock-confinement quickly.
Trailing his free hand up Shouta’s thigh and to his stomach, Izuku reinserts his third finger before sliding that fourth finger inside.
Shouta’s ass is like a vise, squeezing his fingers uncomfortably together, so Izuku grabs his cock in the hopes of relaxing him a little more.
He throws a longing gaze over his shoulder at the lube, then sighs and spits down onto Shouta’s cock, trying to use it to ease the slide of his hand against Shouta's sensitive skin.
Shouta’s belly jolts when the spit hits him, and Izuku checks his face. With his eyes unfocusing and his cheeks flushing, Izuku almost smirks.
The young adult lowers himself to Shouta's belly with a smirk, drawing the large cock inside his mouth to sloppily suck him off as he drags his fingers inside him.
His own neglected cock throbs against the zipper of his pants, and he can feel how wet he’s getting listening to Shouta's chocked moans, whines, and keening.
He ignores it in favor of pulling off Shouta’s cock, now with enough saliva to spit messily onto his dick, nothing but a slick wet glide when his hand takes its prior place to stroke him.
Carefully, he watches Shouta 's face, watches hunger overtake his eyes.
“Please~” Shouta manages, voice deep and husky.
“Hmm?” he teases, his tone curious while he tightens his grip
“ugh- Please Izuku. Hit me, praise me, fuck me, please, anything, please Izuku~!”
Izuku jolts at the requests, or the begs, he supposes. His dick aches in its confinement, and Izuku can't help but agree.
His brain can’t process any fault, too overwhelmed at how hot it is, and he brings himself up to pull Shouta’s long curly and mattered locks.
The man below him arches his back, loudly whining "Izu~!" even as he has to wince at how hard his lover pulled.
Izuku trails a thumb over the man's chapped bottom lip, and whispers to him "Good kitten" which earns him another moan.
“Ready.” Shouta urges, swiping his tongue across Izuku's thumb before it leaves.
“Okay,” Izuku acquiesces, withdrawing his fingers from the tight hole gently, “Roll over, kitten. Hands and knee,” he orders, mostly for Shouta's benefit. One of the things he had learnt from their time together that Shouta really liked being told what to do.
Shouta complies, and Izuku finally relieves himself of his trousers and soaked underwear, tossing them aside. He grabs the lube and coats his dick, giving himself a few firm strokes as he admires the sight of the debauched mate in front of him.
“C’mon.” Shouta urges, not bothering to lift his face from where he’s turned to stare at the bed, his flush out of view for now.
Izuku presses his hands into Shouta’s waist, readjusting him a bit until they align, and Shouta is no longer slumped over the pillow, now his neck was in easier reach as Shouta leans on hands pushed against the wall. it may not be hands and knees, but this position seemed easier.
He eyes the spot behind Shouta's hair, moving it to rest around Shouta's right shoulder as he gets a look at the gland on the back of his neck. An innocuous stretch of skin, as pale and innocent as the rest.
He leans down and breathes in. Shouta’s scent is milder than an alpha’s or omega’s, but the dark chocolate and coffee that mix so well with his damp pine and cinnamon still makes Izuku’s mouth water.
He kisses Shouta’s neck, reveling in the shudder it elicits.
“You sure?” he checks, wanting consent before he goes too far with the submissive beta.
“Yes.” The answer is immediate and definite, and Shouta’s head shifts to further bare his neck.
Izuku licks the spot, immediately noticing the difference in taste when compared to his thigh. The scent is stronger, and tastes like Shouta, like the man he loves, and he doesn’t think he could stop the press of his teeth into the spot if he wanted to.
Izuku’s arm goes under Shouta’s chest, using his forearm to support his weight, as though sensing the way Shouta would slump forward, hands previously holding him up going limp, before it even happened.
The bite had been gentle at first, but scent bursts from the gland and onto his tongue, a musk of arousal, submission and familiarity that has Izuku rutting his dick into the cleft of Shouta’s ass and sinking his teeth in just a little further.
Shouta whines, entire upper body pliant and arching, supported only by Izuku’s arm. Izuku’s nose presses into Shouta's hair, and he inhales deeply.
He feels his hardness against Shouta's bare hole with a kind of acute focus that he’s never experienced before, his usually annoying slick hardly even a consideration in the back of his mind.
In the small section of his brain that’s still capable of analytical thought, he notes that it might just be working. He forces himself to drop his grip on Shouta’s neck, noting the small prickle of blood where one of his canines had gone just a bit too far and broke skin.
Though he assumes a bit of blood is necessary, much like other scent type bonding.
He releases his grip on Shouta’s chest, moving the man's arms to hold himself up using the wall. With some encouragement, the panting beta does so.
Izuku gently licks the bite, cleaning it off blood and comforting his lover.
He’s still grinding himself against Shouta’s ass, chasing his newfound sensitivity. Shouta arches back into it, arms readjusting as he supports his own weight.
His voice is desperate and somewhat slurred when he finally speaks. “Fuck me." he begs in a voice higher than Izuku has heard from him before.
Fuck, yeah, Izuku had almost forgotten. He grabs Shouta’s asscheeks, prying them open to watch his pink hole spread just the slightest bit.
He watches, entranced, as his beta leaks. Izuku has always produced more slick than what was common, but Shouta seemed to be producing 3 times more in half the time. And the omega loved watching it fall out his hole, coat his inner ass cheeks, before dripping down his inner thighs and drenching the bed.
He wants to lick it.
Shouta’s thigh twitches just a bit in response as his breath stutters. Cute. He smiles, and eases his cock forward into Shouta’s heat, hands tightening at the others waist, gasping both at the sensation and the way his erection is already a bit thicker at the base than normal, twitching at the possibility of knotting his mate.
Shouta mirrors the sound that escaped Izuku at the thought. And Izuku presses himself to the hilt far quicker than he had intended to.
He doesn’t sound like he’s in pain, though, just a bit drowsy with arousal, so Izuku starts fucking him at a moderate pace, eyes glued to the sight of Shouta’s hole stretched perfectly around him.
"Ah, ah~, yes, yes~!, Fuck, god Izuku, ah~ Izu, Izuku~ f-fuck, Izuku~!" he moans, and although Shouta was often vocal during sex, this was the loudest he had ever been.
He remembers, suddenly, that Shouta has a prostate, and shifts his angle to thrust down towards his belly, a bit deeper.
Immediately, he’s awarded with a shaky loud moan, and he can’t help but start to fuck him faster, chasing pleasure far more intense than he’s ever experienced with his cock alone.
"Good boy~ good kitty, right? S-so tight, baby... so good for me!" he praises between thrusts.
Shouta’s knees start to slip out from under him, arms coming with, and Izuku chases him down until he’s pressed into the mattress, almost flat if not for the pillow Shouta rests on that they had left from their previous position.
Izuku’s eyes track up Shouta’s spine to watch the way his hands twist in the sheets, then back down to watch him alternately hump into the pillow and grind back on his cock.
Well, he recovered quick. Two can play at that game.
He leans forward, shifting his weight onto his elbows, sliding one hand under Shouta’s chest and the other up to cradle his throat. “So good,” he praises right into Shouta’s ear, fucking him even harder as he tightens his grip.
His dick was pressed in when they fell, and he relished in how deep he was thrusting now.
Izuku both hears and feels the gasp and inhale through Shouta's throat that tumbles right back out in the form of a moan, almost verging on a sob.
He wanted to make Shouta cry from pleasure after hearing that near sob...
Izuku can feel his orgasm fast approaching, almost embarrassed by the little time he had lasted, with his dick beginning to catch against Shouta’s rim as the base grows.
He nips the lobe of Shouta’s ear, trailing down to suck a bruise against the side of his neck.
He can’t even fit the base of his cock in and out of Shouta's tight ring anymore. He doesn’t want to waste the time it takes to force the knot out, fucking Shouta fast and shallow as he chases his orgasm. Shouta humping him much the same.
“Knot me~!” Shouta moans. “God, please, just- izuku, please knot me! Please, please, Pl-ah- ugh~! ” he sobs before a moan is ripped from his throat and he suddenly spurts ropes of white after Izuku tightened his grip on his throat and waist as well as thrusting in harder and giving him a particularly dark hickey. The bed and his chest are quickly covered in his cum as he shouts his mates name when he releases.
Izuku groans. Shouta had tightened around him as he came, causing him to groan and pant as he fastened his pace.
"ah- ah- i-izu~ fu-" shouta stutterdly huffed out every time Izuku thrusts him further into the bed.
Encouraged to keep going, Izuku fucked faster and harder into the overestimulated man below him.
He stops biting hickeys over Shouta's neck and shifts to praise and help the man along.
"G-good kitty, s-so goo- ugh, so good baby! So tight, s-so- ugh~!"
When he sees tears dripping from his squirming, moaning and half in subspace mate, it's his last push before he reaches his release.
Orgasm sparking through him, he presses his teeth right back in that spot at the back of Shouta’s neck, shoving his cock in to the hilt.
Shouta's name is ripped from his throat as he coats the man's inner walls.
His mouth floods with saliva, and Shouta's previously hardening cock springs to life.
He releases a loud shaky moan, rim twitching around Izuku’s knot as his second orgasm fast approaches.
His body goes rigid and tense, heat bursting in his stomach as his system floods with more endorphins, moaning and squirming beneath Izuku.
Finally done riding his orgasm, Izuku collapses onto the bed, depriving Shouta of the glorious friction that was forcing his constantly dry eyes to water.
He rolls off Shouta's back and onto his right side, taking Shouta with him as his right arm slides under the others torso.
“Please,” Shouta begs, “please, my cock,” he continues to sob out, not ready for aftercare or cuddles yet.
Blearily, Izuku tightens the hands on his lovers throat. His right hand, sprawled on the mattress moves to pinch at Shouta's nipples.
Shouta sobs in relief, and Izuku doesn’t have the motivation or stamina to do much but pinch and flick the bud weakly while his left hand holds Shouta's throat tightly enough to be satisfying as he fucks into Izukus limp knotted-inside-him cock.
Izuku tries to mirror the cadence of his partners hips with his own to give him more friction.
Shouta keens a high moan, knot dragging incrementally back and forth across his prostate.
His hand comes back to grab the wrist of the hand playing with his nipple, steadying himself as he tightens almost painfully around Izuku’s knot and comes messily across his stomach and the bed. Again. While moaning louder than Izuku’s ever heard him.
Izuku, more recovered now, moves his hand from his lovers throat in favour of petting his hair. Gently working Shouta through the post-haze of his second orgasm.
His fist clenches on the dirty sheets, but soon his planting his head in the crook of Izuku's neck as he let's the younger spoon him.
“Holy shit.” Shouta mutters, muffled from his embarrassingly raw throat.
“Good?” Izuku asks, wondering if he should get his spare eye drops from his bedside table for his beta.
Shouta huffs a laugh. “I’m never topping again.”
“Hey!” Izuku weakly pinches his cheek playfully. “How are you going to get me through my next heat with that attitude?”
Shouta waves a lazy hand. “We’ll figure it out.”
Izuku snorts, snaking his arms around the other and placing his head on Shouta's as he snuggles himself into Izukus chest.
He doesn't really doubt that Shouta is serious, but either way, Izuku would make it work. How could he knot?
It was, without a doubt, the best sex either of them had ever had.
