Chapter Text
But still, despite midnight declarations and shared heats and the many years they've spent together, people talk. People talk without knowing shit about what they're saying.
Katsuki is used to schmoozing at these parties his parents put on. To keep morale high in their clan, and to make new connections.
It's boring. All Katsuki does is sit on the sidelines and just listen to idle gossip as he waits for it to be over.
Atleast this time, he thought he'd be able to hang out at Izuku's side. He thought so, at least.
Instead, he has to watch Izuku and that damned Todoroki bastard out in the middle of the room, talking casually to one another as others drift in and out of the circle around them. Eager to listen to the two highest ranking Yakuza chit-chat, or whatever the fuck.
Katsuki is seething from where he sits at a table in the back of the room, if only because it's the one place he could find that he could escape the damned gossip.
Or so he thought. A nameless nobody situates themselves just behind Katsuki's table, gushing not-so-quietly to their companion.
"I just don't know why they haven't announced anything yet. Yagi-san is obviously enamored with Todoroki-san."
"Oh really? I thought it was opposite," another extra pipes up. "How often do you see any Todoroki voluntarily spending time with any other member outside of their family? What a powerful couple they make."
Katsuki snatches the glass of wine (alcohol-free because, despite everything, his mom doesn't want him drinking underage. Tch.) and chugs it down. Anything so that he won't have to focus on the conversation happening in front of him.
Unfortunately, it's completely gone by the third or fourth sip. He'd been doing the same thing all night, and he still had hours to go until the event was over. And he can't exactly leave.
So, with a huff, he glares at the duo behind him and stomps his way up to the bar to get another refill.
Along the way, he's intercepted by none other than the love of his life.
"Kacchan!" Izuku beams, his cheeks flushed after laughing at whatever shitty joke Todoroki came up with. And, speak of the devil-omega, Todoroki peeks at Katsuki from Izuku's other side.
"Deku," Katsuki grunts in response.
"I've barely seen you all night. Do you want me to get you another drink? Oh— have you met Shouto, yet? I talk about him all the time."
Katsuki simply grunts again, looking down at his empty glass. He swirls it, though there's nothing left to swirl, and completely ignores when Izuku begins to introduce them.
"Are we done here? I have more important shit to be doing, you know. Other alphas to hang off of."
Without waiting, he ducks past Izuku and continues his march to the near-empty bar. Still, he notices the look of hurt cross Izuku's face before it gets overshadowed with another expression that makes his eyes darken and a scowl cuts past that jovial smile of his.
Good. Katsuki huffs as he plants himself on a free stool, sliding his cup back and forth against the smooth bartop.
It's quickly refilled, but Katsuki stays where he planted himself, if only so he won't have to turn around and see Izuku get all buddy-buddy with whats-his-name Todoroki all over again.
He's so busy glaring into the red pearlescent swirls of his drink that he doesn't notice someone sliding in the seat beside him until there's a hand touching the small of his back.
Katsuki stiffens, biting his tongue so that he doesn't immediately rip into the stranger. Instead, he carefully twists in his stool and travels his gaze up the offending arm to the smug-looking face attached to it.
Oh. It's the kid of one of the families that have been steadily losing power for the last few years. What was it… Nishino? Nishito!
Katsuki quirks a brow at him as he bows his head respectfully.
"It's strange seeing you without your guard dog, Bakugou-san."
Katsuki huffs, immediately turning back to the bar. "That's a shitty pick-up line."
"Oh, but it's true. Every time I've seen you, I've hardly been able to say 'hello' without feeling the pinprick of an angry glare stabbing me in the back."
The youngest of the Nishito family laughs, and his hand drifts higher up Katsuki's back to rest there. As if to publicly state his interest.
Katsuki glances over his shoulder, partly to see if anyone noticed.
And— of course. The one person in the room who matters most to him noticed, and Katsuki bathes in the glower shadowing Izuku's face like it's liquid gold.
"Guess so…"
"You're quite pretty. Such beautiful eyes."
The next hand comes to try and cup against his cheek, but Katsuki twists away from the hold to instead hold his drink up between them.
"You're a touchy fuck, aren't you?"
"I'm drawn to beautiful jewels, you could say."
Nishito steps off of his stool to instead lean directly against the bar. It gives him a few more inches on Katsuki, urging his gaze away from where it was trailing back towards Deku.
He nudges his fingers one last time against Katsuki's back before he lets his hand fall away. They instead cross atop the counter, showing off the number of shiny rings adorning each finger.
"… I can see that," Katsuki snorts. "Overcompensating for something?"
"Had to catch your attention somehow. It's so hard when your precious time is stolen by that… Midoriya fellow."
The tone is rude, even by Katsuki's standards.
"It's Yagi. Thought that news would've passed down to the lower ranks by now," Katsuki shoots back, just as haughty.
Nishito laughs again, raising his hand placatingly. "Of course. But we all know he doesn't actually want that title— he has all of his guards refer to him simply as 'boss', I've heard. So why should we address him as such when he isn't around?"
Katsuki rolls his eyes so hard that his head starts to hurt. One of these guys— bitter that Izuku took up the mantle, wasting their years of schmoozing up to his dad to try to gain favor. Little did they know that Izuku was doing even better for their community than even Toshinori did, to the pride of said father.
"You're an idiot."
Katsuki grabs his drink, gulps it down like a shot, and pushes the cup away from him. Then he hops out of his seat.
"Now fuck off and go suck someone else's dick."
When he turns to leave, though, his arm is grabbed in a tight grip. Those many rings pinch his skin, causing him to wince.
"Hey now, no need to be upset. We were having such a good time. It's not my fault that green-haired bastard has you wrapped around his finger."
And, well… Katsuki never was one with a hard-to-trigger temper. He slaps the asshole with his bare palm, right across the cheek, and tries to yank himself away.
Nishito's grip just tightens as Katsuki's feet slide against the freshly-waxed floor.
"Listen, you grade-school bitch—"
"Get off me," Katsuki hisses, pained. "Unless you want to get thrown across the room."
Nishito drags Katsuki ever closer, until they're face to face and Katsuki has to balance on the tips of his toes. It makes him reflexively release a distressed scent, one that Nishito seems to enjoy by the way he smirks.
Before Nishito can further insult him, though, there's a burst of furious alpha-scent before Nishito's wrist is grabbed by a familiar hand.
There's only a split second for them to react, and all Katsuki can focus on is the influx of feral pheromones that wrap around him and have him straining his neck to bare it in submission.
Izuku isn't focused on him, though, but instead on Nishito and the wrist he's crushing in his palm. The other man is brought to his knees just from the pain, weakly grasping at Izuku's clutch to try to get him to let go.
"Don't ever touch my omega again," Izuku bites. "I won't need my men to hide your body if you do. I'll do the honors myself."
Katsuki gulps, and Nishito pales.
"I meant… no disrespect."
"Liar," Katsuki quips.
Izuku drops Nishito, only to plant his foot on the man's back and have him curl up as if he's begging for his life.
Then, Izuku turns his furious gaze to Katsuki.
"Quiet, Kacchan. I'll deal with you in a minute."
"But, I—!"
Izuku grips him by the shoulder, tugging him close so that Katsuki is held against his side. It does the combined job of shutting Katsuki up and possessively surrounding him in his scent.
"Not. Now."
Izuku's voice is deep, each word outlined by a warning growl. Katsuki's legs reflexively clamp shut, just in time for a rush of arousal to burst forth and drown his underwear.
Izuku must smell it, because his eyelids drop and he takes a deep breath in before he slowly lets it out.
Then he turns to the crowd gathering around them at the upset.
"In case any of you missed it— this is my omega."
And, as if the declaration wasn't enough, Izuku tugs at Katsuki's suit to show his bared neck to the scene. His bite is still red and swollen and fresh, and when Izuku tilts his neck to the side, his own is adorning the same.
"If you touch him, you will be answering to me. If you make him upset, there's nothing I won't do for his honor. He is my mate."
Izuku looks Katsuki in the eye at this, ignoring everyone else around them. The words are meant for Katsuki, next.
"Mine. Understood?"
There's an uneasy, if not quick, agreement from the growing crowd, and Katsuki watches as even Todoroki nods his head.
Katsuki shoots him a smug look, though it's quickly wiped from his face when Izuku hoists him up and carries him right out of the ballroom with little other fanfare.
---
Katsuki grunts as he's thrown onto the bed, scrambling to crawl off of it and stand his ground. Izuku just pushes him back down with a firm hand to his chest, pinning him.
"Get off me," Katsuki grumbles, with much less heat towards him than towards Nishito.
"I don't even know what to say to you, Kacchan."
Izuku is fuming, and Katsuki is hesitant to move when he takes his hands off of him to instead fist them as he begins to yank his own suit off.
"If you'd be willing to listen, you'd know I have no interest in Shouto. He's just a friend. But you go and do this anyway?"
"But if he offered, bet you'd bend him over no problem," Katsuki bites back. "Guess our mating means nothing to you."
Izuku fits his finger against his tie and tugs it off in one smooth motion. Then he does the same to Katsuki's, staring him in the eye the entire while.
"Don't you ever put words like that in my mouth, Katsuki."
Katsuki shivers. The words are like an ice cube dragged down his spine, especially hearing his given name fall from Izuku's lips.
"But apparently you believe that, don't you? Would you have gone with that person at the party, just to get back at me?"
"I wouldn't—"
"Are you sure? Because you acted like such a slut, I can't imagine anything else happening."
Katsuki gasps at the insult. Though that, too, sends an overwhelming feeling of arousal heating its way between his legs.
"Oh, what's wrong, baby? Don't like it when I call you a slut?" Izuku's hand tightens around his neck, keeping him still. "Too bad. If you had been good tonight, I would've called you anything you wanted. Everything you are to me— my heart… the love of my life. Instead you're acting like a spoiled brat— a bitchy princess—"
Katsuki moans at the sudden insult, and everything between them stills.
Then, Izuku grins.
"Yeah? Wanna be my princess, baby?"
"D-Deku," Katsuki wheezes, squeezing his legs shut. He writhes, and just the feeling of his suit pants rubbing against his sensitive cunt is enough.
Izuku stops him, though, yanking Katsuki's legs apart so that the stimulation stops.
"Deku!"
"You were a slut, Kacchan. Naughty sluts don't get to play with themselves without my permission."
Katsuki gasps when Izuku actually rips his pants at the seam, baring him completely to Izuku's gaze. All he has left on are his plain panties and leftover hickeys and bruises from their first time not even a week ago.
Izuku's eyes pass over the markings, but then they zero in on the red, finger-shaped spots around his upper arm. Where he'd been grabbed earlier that evening.
"Oh, what am I gonna do with you, Kacchan? I'll have to wrap you up in our nest to keep you out of trouble."
Izuku kisses the tender near-bruises. Katsuki huffs at him.
"It's your fault for ignoring me all night… dumb Deku."
Izuku's tender kisses stop abruptly. They're soon replaced by a sharp nip to his shoulder, before a warning growl sounds from Izuku's chest. When he presses his face against their healing mating bond, Katsuki's head goes fuzzy.
"Turn over, princess."
Katsuki knows his face must be burning red. He squeezes his eyes shut until Izuku sits up, straddling him. Then he scowls at the alpha and says,
"Make me."
Izuku's nostrils flare, swallowing down the heady scent of arousal flowing off of Katsuki in waves. His eyes are so dark they're practically black, and his face is shadowed both by his frown and by the dim lighting from their curtained windows.
The next thing Katsuki knows, his face is in the satin sheets and his ass is being hoisted upwards, knees settled beneath himself to keep him steady.
When he tries to flail and kick his legs out, Izuku keeps him in place with one hand to his waist, and a firm spank to his ass.
"I said turn over, and show me your pretty pussy."
Katsuki whines at how rough Izuku is being, but his cunt doesn't seem to catch the memo. It's dripping wet when Izuku parts Katsuki's ass, and only gets wetter when Izuku hums in contemplation.
"Now how will I punish you for being so slutty today? Fuck you stupid, until you can't move? Or maybe I shouldn't touch you at all— make you beg for it."
He spanks Katsuki again, making the young omega jerk in his hold. Then he does it again, on the other side.
"St— ah! Stop it," Katsuki pants. "As if you could actually fuck me well enough for that. B-bet you can't even last long enough to get inside me."
Izuku laughs at him. Actually laughs, as if it was a joke. It makes Katsuki feel even hotter, like a small little plaything for his alpha.
Fuck, his pussy is throbbing for it. Katsuki balances himself on one shoulder, angling his head back to watch as he trails his own touch down his body until he reaches the heat radiating from between his legs. Just a little touch…
As soon as his hand touches his clit, Katsuki dissolves into wanton, almost overwhelmed moans. The words 'naughty slut' and 'princess' play on repeat in his mind, Izuku's smooth voice wrapping around his brain like silk. He can't help it as he keeps nudging and prodding and rubbing at himself, nearly forgetting where he is.
That is, until that warm, usually gentle hand of his alpha's comes to punish him again. First, he's yanked away from his clit. Then, Izuku slaps his own fingers down against Katsuki's swollen, wanting clit.
It makes the omega yelp, slamming his thighs shut with an audible noise.
"Alpha!"
Izuku's own grunt follows Katsuki's outburst, and another humiliating moan makes Katsuki sink further against the mattress.
He's not allowed to go fully flat, though, as Izuku simply lifts him by his hips again and squeezes his ass in warning.
"Keep playing with yourself, slut. Since you don't want me to do it for you."
Katsuki's next breath comes out shaky and shuddery, and he bites the sheets to quiet down the embarrassing sounds.
"D-Don't need your help, anyway," he gripes.
He reaches for his clit again, but pauses instead at his cock. It hangs between his thighs, small and weeping for attention. Katsuki clumsily wraps his fingers around it as he spreads his legs all over again, angling his hips just that much more upwards so that Izuku can see it all.
"Dumb alpha," Katsuki gasps as he begins to pump himself. It's different than with his clit, different than when Izuku touched him the first time, but still good. He strokes himself from tip to base, practically humping his own hand for the stimulation. "Fuuuck…"
Izuku hums with him, a soft sound of encouragement. Katsuki's pace stutters when Izuku rubs little circles along the reddened spots on Katsuki's ass, but quickly picks it up again as he feels himself throb for more stimulation.
It's when he's gotten relaxed, near boneless as he huffs and moans and cries out at the stimulation, that Izuku punishes him again.
It just feels so good that of course Katsuki's grip falters again and his cock falls with a soft, wet sound against his upper thigh. Before he can get himself under control, keep bringing himself to completion under Izuku's heavy gaze, teeth bite into the soft, pliant flesh of his ass.
Katsuki cries out both in shock and in pleasure-pain when Izuku pulls back to immediately slap his palm against that aching spot. He does it three times in succession, making Katsuki's skin ripple with the impact, before he lets his hand fall between Katsuki's legs again and feel his cock.
"Ow!" Katsuki hisses, though his hips are already jerking against Izuku's palm.
"I didn't tell you to stop," Izuku tuts. "Keep playing with yourself and show me how much better you are at it."
Katsuki ignores him, or tries to anyway. He's already so close, just rutting his hips back and forth so that his cock knocks against Izuku's fingertips. Fuck, fuck— just a little more…!
Izuku lowers his hand slowly, until just his index finger is rubbing up and down the shaft. Then he drops that touch, too, and spanks the other side of Katsuki's ass.
"Noo!" Katsuki whines. "Hnngh— fuck!"
He hides his face flat against the bedsheets, fisting them against his sharp nails for a moment. Frustrated tears well up against his squeezed-shut eyes, but that's not enough to get Izuku's hands back on him.
Instead, both his cock and his cunt are left untouched as Izuku simply enjoys himself behind Katsuki. Every so often, he'll spank Katsuki to encourage him to hurry up, but otherwise he doesn't touch the needy little omega practically in his lap.
Katsuki forgoes his cock this time, instead reaching directly for his cunt. He sinks three fingers past the entrance, tiny in comparison to Izuku's, and wriggles them in as deep as they can go.
It doesn't feel as good as when Izuku does it, but Katsuki makes do. He immediately crooks them in search of that one spot that Izuku seemed to memorize inside of him, but it feels so good every time he passes over it that he spasms and loses his place.
Katsuki tries to make his hand do most of the work, but it quickly cramps and feels numb. But when he tries to ride his own fingers instead, he can't get the angle right, leaving him frustrated and wanting and dripping against his own palm.
Katsuki yanks his hand out to slap it against the bed, as if throwing a tantrum.
"I can't," he sobs. "Fuck me already, Deku— you proved your point."
"Oh? And what point is that?"
Izuku doesn't stop kneading Katsuki's ass, making the omega moan softly beneath his breath. It feels so much more sensitive after the brief spanking that it's hard to focus on anything except that.
"T-that…" Katsuki stumbles over his words when Izuku dips between his crack and passes his thumb across the bottom half of his slit. "Yesss…"
"'That' what, princess? Tell me exactly what you failed at doing so I can help my baby the way he needs."
Katsuki shrinks, resolve wavering.
"I'm…"
Izuku waits patiently, but Katsuki lets the words die in his throat. Instead, he bites his lips and jerks his head the other way.
"You're so stubborn, princess."
Izuku leaves a kiss in the small of Katsuki's back. "But that's okay. I know exactly what you need."
Oh, finally. Katsuki perks up immediately, shuffling forward on the bed when Izuku begins to sit up. He wriggles his hips back and forth to find the best position, and has just begun to reach behind himself to spread his ass when, instead, he's lifted completely off the bed and instead settled in Izuku's lap.
"Deku!" Katsuki gripes. "This isn't what I wanted."
Izuku makes a noncommittal noise. Katsuki doesn't exactly realize the position they're in until Izuku plants Katsuki's feet flat against the carpet. He's bent over Izuku's lap, like a kid about to be— about to be spanked.
Katsuki's face heats up with the force of his blush, but he doesn't have enough time to argue his case before Izuku's hand is settling against his ass.
"I know. Count for me."
"Wait— ah!"
The first spank is hard and loud between the two of them. Katsuki's feet scramble against the floor, but he's so short in comparison to the alpha that he can only find new purchase on the tips of his toes. It makes his ass stick up that much more, as if he's asking for it.
Katsuki digs his fingers against Izuku's leg, the only thing stopping him from faceplanting back into the bed.
"… O-one."
"Good boy."
Izuku spanks him again, and Katsuki loses his mind. It rocks him forward again, making him lose balance again, but Izuku doesn't pause this time. He spanks again and again, both landing near the tender spots on the backs of Katsuki's thighs.
Katsuki loses strength in his legs quickly at that, and the full weight of his hips pins his own cock against Izuku's lap.
"Two— a-and three!" Katsuki sobs.
Izuku shushes him, his free hand dropping to cup against Katsuki's chin. Then his palm finds its way against Katsuki's mouth, to quiet him more.
"You're being too loud, princess. We don't want everyone to know what a whore you are for me just yet."
His thumb rubs along Katsuki's lower lip, smearing a bit of drool there, before he lays his palm flat and silences most of the gasping pleads.
Then he keeps spanking him. The blows are precise, measured. Each one meant to keep Katsuki focused on the pain of it as it radiates across his backside. His cock didn't seem to mind by the way it stays hard.
Between each slap, Izuku pauses. His hand waiting mid-air for Katsuki's obedient, if not muffled, voice to continue the count.
He doesn't realize tears are spilling down his cheeks until he tastes the salt of it mixing with the spit that starts to drip from his chin.
Katsuki garbles nonsense against Izuku's palm, his fingers dropping from Izuku's legs to instead wrap around his wrist. It keeps his back arched, so that all of his weight is dependent on Izuku.
"Hush, princess. Here— you don't even have to count anymore. Just be a good omega and take your punishment."
And then the spanking speeds up all at once.
What before was a steady, easy to handle pace, quickly grows into something overwhelming all over again. Slap after slap land against Katsuki's tender ass, painting it pink and red all over. Katsuki loses count after the twentieth overall spank almost immediately, but he doesn't lose focus of his each time he jolts in Izuku's hold, his pussy convulses around nothing.
Soon, his wet is dripping down Izuku's thigh.
"Oh, does my pretty baby like his punishment? That won't do." Izuku pauses briefly, only to dip two fingers immediately in Katsuki's pussy and pull them out to show Katsuki just how aroused he is.
Then he wipes the mess on Katsuki's cheek, for him to wear.
When his fingers come back dry, he brings them back to the crack of Katsuki's ass. Katsuki prepares himself for more spankings, his chest heaving (and subsequently rubbing his nipples against the silk sheets).
Instead, Izuku spreads Katsuki's legs open. His fingers slowly slide from Katsuki's chin, prompting him to go boneless and flat on his upper half. When Izuku shifts them a bit, his knees end up back on the bed, so that there's less pressure on his hips.
Then he's made to spread his legs even wider, so that his cunt can feel the cool breeze of the fan rotating above their heads.
Izuku taps his thumb against Katsuki's mound, prompting the latter to try to arch into the stimulation and send him lower.
What he gets instead is another spanking. Directly against his pussy this time.
Katsuki lets out a startled, wounded sound, and Izuku shushes him with a distracted murmur. He's focused on the way Katsuki's pussy had immediately dripped and splattered wet against his palm.
"Looks like I'll have to punish you here more often. Look how eager you are for it, princess. Have I been neglecting you all over again? I'm so sorry, baby."
The soft tone conflicts with the next two spankings that make Katsuki lose his mind. He doesn't know what to do with his limbs each time it happens, the only thing he can focus on is the sound and the feeling.
With the angle coming in from behind, the very tips of Izuku's fingers land directly against Katsuki's hooded clit. The pain is sharp, grounding, and makes him wail on each impact. Izuku doesn't hit him as hard here as he did on his ass, but it's enough.
Fuck, it hurts so good.
His eyes begin to roll as he stuffs his mouth against the bunched up sheets, so that anyone listening from the doorway doesn't hear him start to whine for more.
With each pause, his body jerks forward only to immediately rock back into position, ready for the next swing. The next few spanks have him choking a mix between 'Alpha!' and 'Izuku!', and the ones after that are aimed specifically at where he's most tender, as if to remind him that he's not supposed to like it so much.
But he can't help it when Izuku's cock is pressing insistently against his belly, spreading precum there and reminding him of how it felt to be split on it during his first heat. He wants it inside him now, especially with his pussy so tender and sensitive.
If his cunt had been radiating heat before this, it was basically on fire now. Even without touching with his fingers, he can feel how the swollen lips must be red from the abuse.
Izuku spanks him for the nth time, and then lets his heavy hand rest against Katsuki's spread taint. He thumbs across Katsuki's asshole briefly, just to touch, and it takes every ounce of concentration for Katsuki not to kick up a fuss. He wouldn't survive if Izuku spanked him there, too.
But he doesn't have to worry, because he's quickly rolled onto his back all over again and gathered into Izuku's arms.
"There we go, princess. You took your punishment so well."
Katsuki can't do anything more than cry as Izuku sits them up in bed, letting him settle between his spread legs. Katsuki's pussy aches, and so does his ass, when he tries to lean his weight against the soft mattress.
"Hurts," Katsuki sighs, letting his head rock against Izuku's shoulder. Izuku laughs softly, but nods his head.
"I know. We're almost done, baby. Just a bit more."
More?
Katsuki perks up as Izuku leans him against the headboard, urging him to spread his legs. He's face-up so that he can't hide anything from sight, not his expression nor how he minutely humps his hips up to try to entice his alpha in.
Instead, Izuku sits back on his haunches.
"Finger yourself open."
"Alpha, please…"
"I know, baby. But show me how much you really want it. Be good for me and I won't have to spank you anymore."
It's half a joke but Katsuki is quick to dip his fingers past his swollen pussy lips and part them on either side. Deeper in him is pink and practically untouched, and he can feel a warm glob of his arousal quickly spill out now that nothing is holding it back.
Izuku gathers it up with a few of his fingers, and then uses it to lube himself up. He palms himself, spreading it messily up and down his shaft, until it's glistening with Katsuki's slick.
Then, he shuffles up the bed. Katsuki leans back hurriedly, moving to hold himself open, but Izuku clicks his tongue.
"Finger yourself, baby. Like I said."
Katsuki doesn't even have it in himself to argue anymore. Anything to hurry Izuku inside of him.
He hiccups a bit, unable to stop himself from shaking as he briefly prods his clit just to gather some of that wet up as well. Then he slides just one finger inside of himself, the longest one.
It goes in easy, of course, but he's embarrassed to feel how his cunt twitches and throbs around just that. As if it's waiting for a cock to sink inside so that it can urge the cum out of it.
Instead, he's left with only his own fingers and Izuku staring at him all over again. Except this time, his ass is sore.
Katsuki obediently begins to work his finger in and out of himself, until he needs to add another as his cunt gets looser.
When he adds the second one, Izuku leans just a bit closer, to get a better view. He presses his hand flat against Katsuki's thigh, still soft with baby fat, and nudges his thumb against one of those fat cunt lips to pry it open further.
Katsuki gets nothing more than that, so he keeps fingering himself. He's so wet that there's a noisy squelch when he wriggles the third finger in. Just like last time, though, it doesn't feel as good as when Izuku does it. He can't find that spot in him, and it's more frustrating than gratifying.
"I need you, Deku," Katsuki pleads. "Izuku. Alpha, please… I can't— M-my pussy…" Katsuki's blush dusts him pink all the way down to his chest, because he isn't sure exactly how to ask for what he needs.
But after his punishment, Izuku is eager to treat him. He nods, scooting forward to shoo Katsuki's hands away and instead replace those slim fingers with his own thicker ones.
They go in quickly and eagerly, as if Izuku is just barely holding himself back for one last moment of preparing the omega. He angles his fingers upward, curves them just slightly, and Katsuki sees stars and galaxies.
His cunt is easily played as Izuku finds the perfect rhythm to rub against his inner walls, until he's dripping a steady stream of wet against the bedsheets.
"Feels so good," Katsuki urges. "So g-good, aah—! I need you, alpha!"
"I've got you, my omega." Izuku quickens that pace until Katsuki's legs begin to clamp down on his wrist. It isn't overstimulation, but rather Katsuki holding on for the ride as each wave of pleasure crashes into him, tightening a coil in his belly. Tighter, tighter, tighter until he can't do anything more than breathily moan— then…
When he cums, Katsuki loses himself. It's hard to focus on anything when everything feels good. The fingers inside of him, the sheets tickling against his ankles. The breathless way Izuku mutters his name as he watches him come undone.
It rocks him from head to toe until there's nothing but buzzing static across his body. Then he goes limp, all at once, and Izuku is there to hold him again.
"There we go," Izuku praises gently. "You were so perfect Kacchan."
Katsuki can't respond to that with anything more eloquent than a lovesick sigh, but Izuku doesn't seem to mind. Instead, he slowly tugs his fingers out of Katsuki's still spasming hole.
When he wraps those still-wet fingers around himself, Katsuki feels his tummy flip. His cock is so hard. So dark at the tip with how aroused he must be, and dripping precum.
Katsuki licks his lips, and it's Izuku's turn to blush.
"You still want it, Kacchan? Think you can handle my cock after all of that?"
"Yes."
Katsuki flops towards an open space on the bed and rolls onto his back, spreading his legs eagerly. Izuku drinks in the sight of him, one leg crooked up high with a palm supporting him at the knee to keep it that way. Katsuki didn't train his flexibility for nothing, after all.
Izuku settles himself between his legs, stroking his cock one last time, before he finally slides into the omega. It's what Katsuki had been waiting for all this time.
As Izuku slowly sinks inside of him, though, Katsuki's emotions seem to get pushed out.
The overwhelmed tears that clung to his pale eyelashes start to fall again, and Izuku pauses immediately. Katsuki shakes his head, even as Izuku sends forth a burst of soothing alpha-scent, to calm him down.
"I-I didn't mean to be such a s-slut," Katsuki blubbers, clinging to Izuku. "I just want you, alpha. Only you."
The noises that bubble out of him are precious, as is the sniffling from his congested nose. Izuku lavishes him with kisses throughout the stuttering apology, already accepting it before Katsuki finishes. He pauses halfway in, and Katsuki wraps his legs around Izuku's hips to keep him from leaving. As if Izuku would.
"C'mere… I know, baby. You're not a slut— you're my perfect Kacchan."
Izuku lets his hands dip between Katsuki's legs. "I was just so angry— I couldn't let you go on believing I would want anyone except you. You're mine, just like I'm yours. Okay?"
Katsuki nods, and that's all Izuku needs to kiss him silly.
He continues that slow press inside, splitting Katsuki open with his wide girth. Fuck it's so intense, Katsuki has to break their kiss to pant needily against Izuku's tongue. By the time he catches his breath, Izuku has pulled out a few inches only to sink them back in past his swollen lips.
The aftermath of pain from his spanking mixes deliciously with the influx of pleasure as Izuku passes perfectly across his gspot, and Katsuki is embarrassed as he feels himself get so close to the edge all over again.
"I-I'm not gonna last."
"Let me see you cum, Kacchan," Izuku encourages. "Let me feel it."
The wanton noises urged out of him are embarrassing, but Izuku ruts into him again and again to keep them coming. Each time the full heat of him is shoved balls deep inside him, Katsuki can feel himself teetering back towards that edge.
But he wants Deku to cum, too. He wants to feel it inside of him— and… and feel it get caught inside. Would his knot feel as good stretching his insides as his cock does? Katsuki is sure of it.
He begins to grind his hips in little circles on each inward thrust, grunting with the exertion. Izuku eases his hips up just half an inch, but that's enough to add the sharp sound of their hips slapping together to the cacophony of moans.
Katsuki is so close— he just needs Deku to cum first.
"In me, alpha," he huffs. "I want your knot this time. Want you to breed my pussy."
A tremble travels up Izuku's spine as the words register.
"Fuck, you're so naughty, Kacchan," He groans. "My naughty slut. You're mine aren't you?"
"I'm yours!"
Izuku grins, before dropping his face to nudge it against Katsuki's scent gland.
"Then c'mon, princess," he teases. "Keep being good for me."
The words make Katsuki tense as his pleasure crescendos.
"Cum for me, Kacchan."
Then Kacchan comes undone all over again. He isn't sure if he cries out this time, because the heat of Izuku is all he focuses on. His body overtop of him, his weight keeping him steady against the bed as he's rocked up and down the bedsheets. Their hips don't stop slapping together, the mess of the influx of his cum making it sound that much more lewd.
Izuku huffs as he sits up suddenly, yanking Katsuki up with him. He plants his palms against the soft of Katsuki's hips, fucking up into him.
"Gonna breed you so good, omega. Gonna pump you full of my cum 'til we see it here."
His palm shoves against the underside of Katsuki's tummy, before it drops lower so that he can thumb at his clit to keep his pussy milking his cock for its spend.
"I want it!" Katsuki moans. "Alpha!"
Izuku bites him, just below their mating bond. It's partly a way to keep Katsuki still as he feels the first spurt of cum heat the deepest part of his cunt, but mostly just so that he can taste Katsuki's pleased omega pheromones directly from the source.
Katsuki jolts each time he feels a strong burst of cum fill him up, though it's nothing compared to the quick swell of the knot that catches just past his already stretched rim. Only a few drops of cum escape before it's locked inside of him, sealing the rest.
Still, Izuku humps him for what he's worth. Katsuki is sure he's slurring nonsense as he paws at Izuku's back, doing his best to have his insides swallow it all down.
By the time it quells, Katsuki's voice is hoarse with his moans, and his scent gland is throbbing just as much as his pussy is.
By the time Izuku's shoulders drop, doused with slobber as Katsuki absent-mindedly passes his tongue across his scent gland, too, Katsuki is entirely out of it.
All he knows is his alpha, pleasure, and contentedness.
He purrs as Izuku shifts, gathering a clean blanket at the end of the bed to wrap around them and stave off the chill from their sweat-slicked skin.
Then he, too, flops out on the bed so that they can cuddle as they both come down from their combined high. He grunts and joins in on Katsuki's purring every so often, stopping only to nuzzle his face against his omega's cheek.
Katsuki doesn't realize he's drifted to sleep until he blinks his eyes open again some few hours later. It's darker out than before, and there's the soft sound of midnight ambiance filtering in through the closed window. The moon is beaming directly in his face, and he grunts as he jerks his head the other way to immediately try to fall back into his pleasant dream.
Izuku is still beneath him, and sleepy hands pat at his lower back.
Izuku breathes a soft, "Kacchan," rubbing gentle circles into his skin. His cock is still inside, keeping them locked together.
Katsuki rubs the sleep out of one eye just to watch his alpha for a few moments. How his chest rises and falls with his relaxed breath, how his eyes flicker back and forth as he dreams. His alpha is so handsome, so perfect.
Mean when he wants to be, though. Katsuki winces as Izuku's hand strays just an inch lower and nudges against his tender ass.
Still, even that sends a giddy feeling through Katsuki and has his heart beating like a little bird's wings.
Katsuki lays his head back against Izuku's chest and snuggles in, to fall back asleep.
There's no other alpha Katsuki would choose. And now he's sure that there's no other omega Izuku would have.
Just before he falls asleep, Katsuki makes a promise to himself to take care of Izuku for as long as they're together. Even when he's being a brat, he'll love him for as long as he's able.
Forever, then. He already knows Izuku will do the same.
