“We’re both omegas so it’s fine.”
That was the line that Katsuki had used to finally convenience Shoto to heatshare. The other omega had been so reluctant to do anything with Katsuki despite the fact that their heats had been syncing up lately and it was normal for omegas to heatshare. He was too busy being worried about the bullshit his traditional as fuck family had taught him. Just listening to Shoto go on and on about how it was “beneath him to touch himself” and “he was only meant to be used by his alpha” made Katsuki roll his eyes.
It took fucking Izuku overhearing Shoto saying that shit in the common room and subsequently telling him that was not how that worked, to get the dense omega to finally start listening to Katsuki.
Slowly but surely, Katsuki had broken down Shoto’s resolve. He taught him about omega heat shares, pulled up articles that mentioned shit like how it was healthy for young omegas to have a space to safely explore themselves without the overbearing presence of an alpha or whatever, and he even had Dunce Face weigh in for good measure. Shoto had been shocked by all the information, eyes widening and lips just slightly parting as he took in the information. Katsuki tried not to think about how cute a confused and awed Shoto looked.
It wasn't that he particularly liked Shoto, or had a crush on him or anything, the other omega just smelled nice. Like a crisp winter night and marshmallows roasting on an open fire. The scent was so intoxicating lately that Katsuki found himself hovering near Shoto much more often than before. He had the urge to just bury his nose into the crook of the omega’s neck and lick over the scent gland there until he tasted marshmallow on his tongue.
He'd spent a number of nights rubbing at his clit and moaning softly into his pillow as he thought about his own scent of cinnamon ginger tea mixing with that warm marshmallow. Wanted their scents to mingle and turn even sweeter with arousal and rub off into his nest.
… okay, maybe Katsuki had a crush.
But he sure as fuck was not opening that can of worms at the moment. He was too busy making sure he had everything ready for Shoto and his heatshare. Katsuki had gotten plenty of water bottles, a few bentos to put in his mini fridge, and lots of snacks. He'd also cleaned up and tidied his room and then spent an hour or so fussing over his nest. Katsuki needed it to be perfect if he ever wanted to do this with Shoto again.
There was a light knock on his dorm door and Katsuki hurried to make himself presentable while stalling a little so he didn't look desperate to open the door. When he finally opens it, Shoto stands in front of him. He looks normal except for his cheeks that are slightly flushed, his pupils were a little bigger than normal, and the crisp scent of chilled air and softly melting marshmallows wraps around Katsuki’s brain. He subtly tries to take in deeper lungful's of it and feels his stomach twist in arousal, slick starting to gather between his thighs.
“Hi,” Shoto says, clutching onto the little bag in his hand a bit more.
Katsuki huffs, “Get in here Halfie,”
He pulls Shoto into his room and locks the door behind them as the other omega stumbles in. Shoto stands there awkwardly for a moment before opening up the bag in his hands.
“I um … I brought some of my nest items, like you told me to,”
Shoto’s scent was all over the large nightshirt and thick blanket that he pulled out. Katsuki has to resist the urge to grab the items and rub them all over himself. Instead he nods his head and points towards his nest, “Go ahead and put them in the nest,”
Shoto looks over at Katsuki’s nest and his cheeks grow a little bit pinker, “I don’t want to mess up your nest. It looks very pretty,”
Katsuki’s knee jerk reaction is to sneer. “Just do it! I wouldn’t let you do it if I thought you’d fuck it up,” He barks out, but his heart is beating a little faster and his omega is practically running around in little circles with joy from the fact that Shoto likes his nest. He called it pretty. It was a very high compliment from another omega and Katsuki couldn’t help but feel smug about it. Still he shoved down the frilly little impulses popping up in his mind.
That shit was so embarrassing.
A nod is given from Shoto and he carefully makes his way over towards Katsuki’s nest. Gently he crawls in and starts to weave in his items. Katsuki stares at Shoto kneeling in his nest, heat brain starting to take over just from the sight of it. It has him frozen and imagining how good Shoto will look once he strips off his clothes and enters into a full heat. He wondered if Shoto’s pussy would taste just as sweet as he smelled.
He doesn’t even realize the little growl he’s letting out until Shoto looks back at him. Big mismatched eyes blinking up at him in concern. Katsuki cleared his throat to stop the growling and made his way over to sit in the nest too. Shoto looks at him expectantly.
“So what now?”
Katsuki sighed, “Slow down Halfie. Neither of us are in full heat yet so just relax. We can watch a movie or something for now,”
“Oh, okay…” Shoto says quietly. Katsuki can’t tell if Shoto seems disappointed or relieved.
They both settle into the nest after Katsuki puts on some weird ass conspiracy documentary that Shoto wanted to watch. He tries to pay attention to the documentary but it’s hard. His brain is constantly thinking about how close Shoto is, Katsuki can feel the heat of his skin getting warmer each passing minute. He’s leaning back a bit so Katsuki’s eyes are very easily able to trail over the back of Shoto’s neck and his shoulders – all the soft exposed skin that’s just sitting there for the taking.
Shoto’s skin was pale, easy to bruise if all the training from class had anything to say about it, and Katsuki wanted to bruise it in a much different way. He wanted to kiss the flushed skin, wanted to lick it, suck on it, sink his teeth into it. His gums hurt from the way his canines ached with the need to claim. Shoto’s hair was nice too, he could already picture it tangled between his fingers while they kissed or while he put Shoto’s pretty mouth to work. Fuck, Katsuki shifted his legs a little and Shoto jumped.
Katsuki raised a brow at the other omega, “You good?”
“Sorry,” Shoto glanced back at Katsuki and bit his lip. Katsuki watches the action like a hawk, “I’m just a bit nervous, I guess. I’ve never … done anything. Especially not with someone else,”
“Huh? You’ve seriously never done anything!?” Katsuki asked as he sat up straight, slightly pissed off at the mere thought.
Shoto nodded in agreement, “I’ve told you I was raised to … not do that,”
“Yeah you fucking told me but I didn’t think you actually followed all that shit the whole time,” the blond growled, “So … what? You’ve never touched yourself? Not even a little? How the fuck have you been getting through your heats?”
The blush on Shoto’s face grows, “I just kinda … lay there. I’ve grinded against stuff a little but I usually try to sleep through the waves,”
“What the fuck!?” Katsuki exclaims. That was so fucking ridiculous that Katsuki felt his own pooling heat die out a little. Anger rolled through him and turned his scent sharp, peppery, and sour like a lemon. Shoto frowned and tried to make himself a bit smaller.
“Why are you mad?”
“Because,” Katsuki tries hard to reign in his scent, breathes deeply to keep his palms from sparking up, “That’s the most fucked up shit I’ve ever heard. It’s not healthy in the slightest and you’re supposed to touch yourself during your heat. Or at least get some fucking toys. It helps with the cramping and general pain,”
“... What?”
“Oh my god, I’m gonna kill your stupid fucking asshole family,” Katsuki growls out. “Okay, walk me through this shit. You’ve never once touched your own pussy?”
“N-No,” Shoto’s blush has reached the tips of his ears and his eyes look away from Katsuki’s.
“Nothings been in your pussy? Not even your fingers?”
“No,”
“You said you’ve grinded a little, did you cum?”
“No, I was too tired to get there. It was also … painful,”
“Have you ever cum during your heat?”
Shoto pauses, takes a second to think, and then answers, “... No,”
“God fucking damn Halfie. Have you even kissed anyone? Scented someone?” Katsuki asks. He was starting to wonder if this was why Shoto was so fucking stiff all the time. If Shoto had never gotten off or had any of the basic ass necessities of being scented and given some type of physical affection as an omega it would explain why he had been so confused about heatsharing. Actually, it would explain why he seemed so uncomfortable and confused about how everyone in class acted.
He’d seen Shoto staring at the way the alphas would shower the other betas and omegas in the class with attention. A lot of them had taken to cuddling and giving each other small peaks on the cheek and for those more comfortable actual kisses. Hell, even Katsuki got scented by Izuku and Kirishima regularly. Shoto had never participated and most of their classmates just assumed it was because he wasn’t comfortable with it, but now Katsuki knew that wasn't the case. Shoto just straight up didn’t know what the fuck was even happening.
“Sort of?” Shoto answered.
“The fuck do you mean sort of?”
Shoto shifted in the nest, “I mean … my siblings would scent me sometimes–”
“That’s not the same thing,”
“–And Izuku kissed my forehead once,”
Katsuki rolled his eyes, “So you’re really not experienced at all. Do you even want to ‘save yourself’ for some fucking alpha or whatever bullshit they fed you?”
Shoto frowned again, “I don’t know … maybe? The thought is nice, I guess,”
“But? I don’t see you going around trying to get any suitors?”
“But I’m not sure how to approach alphas for stuff like that. My heats hurt, they’re painful and I wish they weren’t. But I just always figured that I’d be set up with some other powerhouse hero family’s alpha kid at some point…”
Katsuki thinks he might rip out his own hair, “Jesus christ. That still doesn’t answer my question though. Do you want that?”
Again, Shoto goes quiet. He fidgets his fingers a little and Katsuki can literally see the gears in his pretty little head turning. Then after a minute he finally answers with a soft, “No,”
“Good, that’s what I thought,” Katsuki nods his head and leans back into his nest again. Scent finally mellowing back out and the change makes Shoto relax too, “Now come over here. I’m about to change your whole fucking world,”
Shoto seems a bit confused at first, but when Katsuki pats at his thighs Shoto gets the idea and crawls into the blond omega’s lap. He straddles Katsuki’s waist, hovers a bit before Katsuki slowly drags his hands up the back of Shoto’s thighs and just brushes the sides of his ass before gripping his waist. Katsuki lowers Shoto’s hips down so he’s actually sitting down. When their hips meet Katsuki feels the air between them grow a little more heated. Shoto’s skin is warm under Katsuki’s hands and with their faces getting so close together he can really take in just how pretty the other omega is.
Pretty white and red hair dangling over gray and turquoise eyes. The pretty blush on his cheeks accentuating the scar over the left side of his face. Pretty pink lips wet and parted as he looked down at Katsuki. Really, Shoto was gorgeous – resident pretty boy of the class and Katsuki couldn’t agree more. And his scent was absolutely divine to Katsuki’s omega. He was definitely gonna get scent drunk off of him and that only served to make his cunt leak more.
“How do we …?” Shoto started, voice barely above a whisper.
Katsuki let one hand trail up Shoto’s back, up to his neck, fingers tugging slightly at the ends of his hair. “Get closer,”
Shoto swallows and lowers his face down until their lips are brushing and Katsuki’s eyes are fluttering shut, “Like this?”
“Yeah,” Katsuki tilts his head up just slightly to push their lips together.
The first taste of Shoto’s lips has him moaning. They were so soft, the perfect mix of warm and cold, and Katsuki shifted his hand to the back of Shoto’s head to deepen the kiss. Shoto awkwardly tries to move his lips but Katsuki takes the lead and guides him. Pulls him away with his hand whenever Shoto’s rhythm got messed up and brought them back together with a slower pace.
Eventually, Shoto gets a hang of kissing and they melt into each other. Katsuki moans when Shoto shuffles closer, scent turning sugary sweet with need and desire. And then the very obvious scent of slick comes from between Shoto’s legs. Makes Katsuki growl into their kiss and he can’t stop himself from breaking away from those perfect lips to kiss down Shoto’s throat. The other omega whines at the loss of Katsuki’s lips on his but moans when he feels a wet tongue lick over his scent gland and shivers rack through his body.
“Fuck, you smell so fucking good, baby,” Katsuki groans before his teeth clamp down around that flushed scent gland, sucking and licks up the honeyed oil that provided Shoto’s scent.
Shoto moans brokenly, body shuddering and hands digging into the nest, “O-Oh that’s– hnnn … that’s r-really intense,”
Katsuki drinks down the taste of gooey marshmallows until he physically can’t stand it anymore. His whole body was hot. He’s sure that when he finally popped off of Shoto’s scent gland his eyes were blown wide in lust. Quickly he presses their lips back together, adding his tongue this time. Katsuki feeds the taste of Shoto’s own scent to him through their kiss. Rubs their tongues together and then wraps his lips around Shoto’s little tongue.
The wet sounds of their tongues and lips meeting could be heard over the stupid documentary that they’d completely forgotten about and only served to further turn them both on. Their heats slowly started to consume them and the thrumming buzz under Katsuki’s skin grew into a blazing burn. He could feel slick starting to leak out of his cunt and couldn’t help but roll his hips up against Shoto’s.
A broken little moan gets pulled out of Shoto at the action and he instinctively grinds his hips down. Katsuki couldn’t be more glad that they were both wearing shorts, the soft fabric created just the right friction on his clit and he let his hand squeeze at Shoto’s waist to help their hips move together fluidly. Shoto can’t seem to keep up with their kiss now that his hips were moving against Katsuki’s. Their kiss breaking down into them simply panting and moaning against each other's lips.
“Wait,” Katsuki stops moving his hips and Shoto’s brows furrow in response but he stops too. Katsuki shifts their legs so that one of Shoto’s is on the outside of his own and then encourages Shoto to lower his hips again. This time he’s sitting perfectly on Katsuki’s thigh while Katsuki gets Shoto’s thigh pressing up against his pussy as well. “There we go,” he breathed out.
Shoto moans at the new position and starts up his grinding again without having to be told. Katsuki can feel the wet little trail of slick being made on his thigh with every back and forth motion. It makes his skin burn with the knowledge that Shoto was rubbing his slick into his skin like this and he leaned up to capture the omega’s lips once more. The noises that Shoto made were so fucking hot. Needy little gasps that showed just how sensitive and hungry the poor boy was. The poor thing had been starved of attention.
Just when they were really getting into the motions Shoto jerked and let out a hiss of pain.
“Ow, ugh … I t-think, I think my heat hit …” Shoto groaned. “My insides are cramping,”
Katsuki quickly halts his movement and tries to stop Shoto from curling up. “Don’t do that shit, it’ll only make it worse. Your insides are fucked up because your pussy needs something in it,”
Shoto flushes at Katsuki’s words, “What do we do?”
“God, sometimes I think your brain might be made of ice,” Katsuki huffed, “Just try to relax. I’ll take care of you Halfie,”
“Okay … hurts,”
Katsuki strokes his hand up and down Shoto’s back to soothe him, “I know baby,”
He pulls the dual tone haired omega back towards his mouth to give him slow, deep kisses. A distraction while his other hand travels over Shoto’s waist and slips into his shorts. It’s hot inside Shoto’s shorts, damp from all the slick that had clung to the fabric, and Katsuki swallows up the sharp gasp that Shoto makes with his own mouth as his fingers slide through his bush and straight to his clit.
Instantly, Katsuki’s fingers are covered in sticky slick. Shoto shudders against his fingers, hips squirming in need and Katsuki has to shush his little whimpers by rubbing at Shoto’s sensitive clit. Just the few strokes he had done had Shoto choking back moans and drool pouring out of his mouth. He clings to Katsuki, lips moving furiously and hungrily.
“Fuck, oh my god,” Shoto moans when Katsuki’s finger press a little harder and brushes down a bit farther over his sensitive clit, “W-What are you touching?”
Katsuki doesn’t know whether to laugh or be pissed off, “I’m touching your clit. It’s gonna get a lot of fucking attention this heat,” Then Katsuki finally lowers his fingers, slides them easily through Shoto’s soaked as fuck folds and finds that fluttering hole. Katsuki can literally feel the harsh, rapid squeezes of the omega’s cunt. It was begging for something to be shoved in it so desperately it had been causing Shoto to cramp up in pain this whole time. It’s almost too easy for Katsuki to slip two fingers in. They get sucked in immediately, Shoto’s walls clamping down on them in relief, “And this is your tight as fuck hole. Goddamn, you’re gripping me so hard,”
Shoto moans loudly, all high pitched and slutty, and Katsuki forces his fingers to move. He pushes them in and then pulls them out just slightly only for Shoto’s cunt to suck him back in. For once the painful cramping heat in Shoto’s stomach is calmed. Katsuki’s fingers fucking into Shoto’s pussy has the omega literally collapsing onto him in delirious pleasure. He breaks their kiss and buries his head into the crook of Katsuki’s neck, pressing his nose into Katsuki’s scent gland before moving his lips to the area to lick out that cinnamon and ginger taste while his hips start to bounce on thick fingers.
If Katsuki had been an alpha he’s pretty sure he would have popped a knot by now just from how fucking wet Shoto was. He was constantly pouring out slick, his shorts were definitely ruined, and the squelches from each thrust of his fingers were obscene. Not to mention the way he had latched onto Katsuki’s scent gland and was moaning against it as he rode Katsuki’s fingers. It was a desperate sort of humping and when Katsuki let his palm fully rest over Shoto’s clit to give him more friction, Shoto greedily took it. Fucked his hips down harder, rolled them forward just so he could get more pressure on his clit like a practiced whore.
“That feel good, baby?” Katsuki chuckles.
“Yes~” Shoto whines, pulls himself away from Katsuki’s neck and looks at him with such dazed pretty eyes, “Feels so good,”
Katsuki feels his own clit pulse at the look and can’t help bring his unoccupied hand up to Shoto’s throat. He squeezes just a little and gets the loveliest little breathy moan ever before he growls and brings their mouths together.
“Gonna make you cum, Halfie,” Katsuki states against Shoto’s lips, “Gonna make your pretty little cunt squirt all over my fingers,”
Shoto nods in approval. Kisses Katsuki more and clenches around his fingers at the statement. Every fiber in his body knew that Katsuki would deliver – even if he hadn’t cum before much less squirt, whatever that was, he knew that Katsuki would make it happen. Katsuki works his fingers harder, tries to get them as deep as possible so he can press directly on that one spot that had Shoto nearly screaming into his mouth.
He fucks Shoto’s pussy hard and fast, and it doesn’t take much. Shoto’s moans grow louder, and more frequent, hips stuttering in their rhythm just slightly as he chases that high and Katsuki thinks it’s the most gorgeous thing, “Fuck … K-Katsuki, something–”
“Yeah, baby, that’s it. Just let it happen,” Katsuki can’t take his eyes off of Shoto. He swears that Shoto was trying to kill him with the way he said his fucking name like that.
Then it happens. Shoto’s body goes rigid, his eyes roll back, mouth dropping open in a wanton moan and he cums. Cums so hard his legs start to lose feelings as slick gushes out of his hole. Katsuki keeps fucking his fingers in even though Shoto’s cunt has him in a vice grip. He keeps going because he knows that Shoto is right there on the edge of squirting and with one more well done thrust Shoto does just that. He squirts all over Katsuki’s hand and his whole body convulses with the force of it.
“Breath baby,” Katsuki mutters against Shoto’s neck as he presses kisses against it.
Shoto struggles to follow instructions but eventually he starts to breathe through the orgasm and it makes his brain and pussy tingle even more. When Shoto stops squirting all over Katsuki’s lap he pulls his fingers out slowly. With a wet pop they slide out and Katsuki finally registers just how fucking ruined Shoto’s shorts are. Shoto had made an absolute mess of them and they would probably have to be thrown out. Katsuki tries to push down the impulsive want to just keep those damn shorts so he can use the slick ruined fabric to grind against.
Pulling his fingers out of Shoto’s shorts, Katsuki looks at his drenched hand. Slick and cum slide down his fingers and before it can drip down to his wrist Katsuki is shoving them into his mouth. Nearly fucking cums just tasting Shoto’s slick like this. Shoto’s absolutely fucked out, slumped against Katsuki’s chest but upon hearing the very enthusiastic sounds of Katsuki fucking his own mouth to suck off Shoto’s taste and moaning he glances up at the blond.
Watches as those pretty red eyes grow more and more cloudy with lust, the black of his pupils blowing out the more slick he consumes. The way he didn’t stop licking until his hand was absolutely clean had Shoto’s pussy aching again already.
Katsuki turned his eyes towards Shoto as he smelled a new wave of slick start to drool out of his pussy. He growls and flips them around in the nest so Shoto’s back is pressed into it. He makes quick work of pulling off Shoto’s ruined shorts, tossing them across the room to hopefully never be found by Shoto ever again, and then spread Shoto’s legs. He pressed Shoto’s knees into the soft nest so that his whole pussy was exposed and fuck. Shoto’s cunt was leaking slick and squirt, thick and glossy, and covering his thighs and gluing his pussy lips together.
The sight was so fucking hot that Katsuki had to dive right into it.
His face gets smeared with all that sweet slick as he starts to eat Shoto’s pussy like a starved man. Wraps his lips around Shoto’s sensitive clit and sucks. Shoto’s hands are scrambling to grip at his head, hips rocking up into that warm and wet mouth. Katsuki is positively pussy drunk already. Addicted to the sweet taste of Shoto’s slick and even more so his cunt, as his tongue flattened out and licked wide stripes up through soft folds.
“Yes yes yes, oh fuck! Katsuki! K-Katsuki~” Shoto moaned brokenly.
Katsuki buried himself in that pretty pussy further. Felt the slick start to coat his chin and drip down his throat and it just made him hungry for more. He slid his hands down from the underside of Shoto’s knees to his thighs and used his thumbs to pull apart Shoto’s folds even more so he could get deep in there. Katsuki could feel how doing that exposed Shoto’s pulsing hole and he finally moved from that little clit down to Shoto’s hole.
The first thrust of his tongue into the throbbing hole has Shoto screaming. His head gets thrown back as he pushes Katsuki’s head closer in order to get that tongue farther inside of him. Katsuki thrusts his tongue in and out of Shoto’s cunt before sliding his fingers in too. Shoto’s legs tighten up around the sides of Katsuki’s head, suffocating him on that pussy. Katsuki fucks in two fingers then three and spreads Shoto open for him to pour his own spit and drool into.
“God you’re so fucking wet Halfie,” Katsuki groans as he pulls away for a moment. A string of slick still connects his lips to Shoto’s pussy. He’s memorized by the way Shoto’s cunt swallows up three of his fingers like it was nothing while still being so damn tight. “You always this wet?”
“I d-don’t know,” Shoto stutters out, hands pressing against the back of Katsuki’s head in need of more.
Katsuki ignores the pushes in favor of teasing Shoto, “You don’t fucking know? Tell me Shoto, how many pairs of shorts have you soaked through? How many pairs of panties? Do your sheets get stained with all the fucking slick you make, huh?”
Shoto clenches around Katsuki’s fingers, “I … I have to take off my shorts for my heat. Keep a heat t-towel under me so I don’t mess up my sheets,”
“Fuck, just the perfect little omega whore. It should be a fucking crime for any of your delicious slick to just get soaked up by some fucking heat towel,”
Another desperate moan and delicate little hands pushing at Katsuki’s head. Shoto’s hips are still rocking and pushing onto Katsuki’s fingers but he wants Katsuki’s tongue again. “Please Katsuki,” Shoto whines.
Katsuki gets back to work after hearing such a sweet little whine come from the other omega. He had just discovered the wonderful feeling of an orgasm and Katsuki needed to make sure that Shoto wouldn’t forget who gave him that experience. He was going to engrave his tongue and fingers into Shoto’s pussy so that it wouldn’t forget. Would make the omega think of him every time he touched himself or hooked up with someone else. He wanted Shoto to think of him the next time someone else gave him head and know that no one would ever fucking compare.
It doesn’t take much to set off Shoto. The way his pussy was gushing and begging for more orgasms meant all Katsuki had to do was play with Shoto’s clit as he fingered him hard. Flicked his tongue over the little nub over and over before sucking, making a show of loudly slurping up all the slick that’s been pouring out, and repeating. Keeps his jaw working until he feels Shoto’s legs tremble and his hole clamps down even more on his fingers.
Shoto cums with a gasp, and Katsuki looks up at the way Shoto’s back arches up off the nest and he throws his head back again while his eyes flutter. He tries to breathe through it like Katsuki taught him and it just ends up lengthening the orgasm. Hot and cold tingles rushing through his body as his quirk activates for a second. Flickering on and off while Katsuki drinks down the cum rushing out of him.
The sight had Katsuki squirming, his own pussy had been neglected the whole time and his heat was starting to demand his attention. He pulls his fingers out of Shoto’s cunt, they’re shiny with slick and squirt and cum, and as much as Katsuki wanted to shove them back into mouth he had a better idea. Shoto was lying limp on the nest trying to catch his breath so Katsuki shifted to lean back and pulled his shorts to the side.
Little strings of slick stuck to Katsuki shorts and broke apart as he uncovered his own pussy. Swiftly he shoves his soiled fingers into his cunt and instantly it makes him cry out in relief. His head tilts back as he moans, fingers fucking deep into his tiny hole. The stretch always hurt a bit, his pussy too small for his own good, but the heat coursing through his veils meant he was operating like a slick machine. Even still, it was like his body could sense the difference between his own slick and Shoto’s and it made his insides tingle as he mixed their slick together.
Katsuki bites his lip as he roughly thrusts his fingers in and out, racing towards his first orgasm, the palm of his hand smacking against his clit. He spreads his legs even wider, whimpering with need and lets himself push up his shirt a little to pinch at his nipple. The sensitive nubs have his hips rolling down onto his fingers faster and harder.
“Shit,” he groans, so close to the edge.
There’s light shuffling from the other side of the nest. Katsuki’s eyes snap open, having closed at some point, and finds Shoto watching him. His cheeks flush a bright shade of red, but Shoto doesn’t seem to notice. He was too busy leaning in close to Katsuki’s pussy. Transfixed by the way Katsuki’s slim, pretty fingers plunged in and out of such a tiny hole.
Shoto was fucking eye level with his cunt and Katsuki felt his legs trembling and his fingers speeding up. A moan was involuntarily ripped out of him when he felt the ghost of a breath over his thighs. Fuck, Shoto was practically one step away from eating him out and Katsuki can’t take the mental image of that.
“It’s so small,” Is what comes out of Shoto’s mouth. And Katsuki falls head first into his orgasm.
He quickly pulls his fingers out as slick gushes down his trembling thighs and instead focuses on his clit so he doesn’t fucking squirt on Shoto’s face right away. “Shut up,” he growls but there’s no real bite behind it.
Katsuki rides out the waves of euphoria until his hole starts to clench around air begging for something inside him once more. His brain, however, was still fixated on the way that Shoto had called his pussy small. It made heat pool in his stomach and slick pour from his hole. He fucking knew that his cunt was tiny. It pissed him off sometimes because it was hard to even really finger himself half the time and it was also a bit embarrassing during times like these, when he was heatsharing and people could look at it.
But Shoto … the pretty omega had said it with such wonder in his voice. Like he couldn’t believe that Katsuki had been hiding that from him this whole time. Shoto’s face is still buried between Katsuki’s thighs when he pulls his fingers away from his throbbing clit. The sight has Katsuki forgetting how to breathe for a second. Shoto’s cheeks are flushed, eyes blown wide with lust as he stares at the other omega’s sticky cunt, and his lips were parted just slightly. Katsuki could see the way Shoto’s tongue licked over his lips and he swallowed down some of his drool.
Dual colored eyes shift up to meet Katsuki’s, “It’s really pretty Katsuki,”
Katsuki almost explodes the whole fucking room, “Fuck off Halfie! Don’t say stupid shit like that,”
Shoto tilts his head a little, “Sorry? But it’s true. Your pussy is really pretty. Tiny. Wet. Can I … can I lick it? Like you did for me?”
“Fuck,” he says brokenly and a little hoarse. That time Katsuki’s palms do spark up. He can’t respond verbally so he just nods his head and pulls off his shorts.
When he’s fully exposed, Shoto lets out a little gasp. His hand gently touches Katsuki’s thighs and he takes in the view of the blond's pink little pussy. With his legs spread open, Shoto can see everything. The pudgy little folds of Katsuki’s pussy spread to the side to show off a tiny hole dripping cum and slick onto the nest and an even tinier clit. His whole cunt was a fiery pink and Shoto just can’t resist the urge to kiss it.
So he does.
Slowly presses his lips to Katsuki’s clit and makes out with it. Katsuki’s fingers dig into the nest to try and stop the trembling of his legs, but it’s no use. Shoto’s soft mouth feels heavenly on his pussy and when he feels Shoto’s tongue slide over his hole and clit all at once he moans high pitched and needy. Shoto purrs at the sound, vibrating his tongue against Katsuki’s sensitive cunt, and starts to enthusiastically lick and suck up all the slick gushing out.
Katsuki’s slick coats his tongue and it’s the most addictive spicy sweetness. Has Shoto burying his head into the pretty cunt more. He lacks the finesse that Katsuki had, but he makes up for it in other ways. Like how his mouth seems to get warmer, his tongue feeling cooler in contrast. And his lips close over Katsuki’s clit to suck at it, making it swell just a little bit. Then he pushes his tongue against Katsuki’s sweet little hole.
Shoto barely gets the tip of his tongue inside of Katsuki. He pulls away and Katsuki can see all of his slick coating Shoto’s lips and chin and the way that the other omega is so fucking focused on his pussy is insane. Long fingers pull at the sides of Katsuki’s hole, opening it up a bit more, before he once more shoves his tongue in him. He gets deeper this time. Feels Katsuki’s pussy clench and squeeze around his tongue greedily.
“Ngh … Sho–” Katsuki can’t get out words. His insides were so sensitive and feeling that warm thick tongue sliding in and out of him, taking scoops of his slick to swallow down, was overwhelming.
Then Shoto moves one of his hands towards Katsuki’s clit. The first touch has the blond omega screaming. His hips buck against Shoto’s mouth. His hands are sparking again and he quickly tries to pat his palms dry against the nest. Katsuki’s heart was racing, the only thoughts in his head being cum and fuck. He starts to desperately hump against Shoto’s mouth, legs locking around that perfect face and pulling him in deeper towards his cunt. Shoto happily complied and alternated between rubbing at Katsuki’s clit with his fingers while tongue fucking him and sucking at his clit while licking all over that sweet honeyed pussy.
The only time Shoto pulls back is when he needs air, but then he’s right back at it. When he pulls back this time though he looks back up at Katsuki like a wild animal.
“How do I? What you made me do … squirt?” He asks, out of breath.
“Fingers. Two,” Katsuki gasps out quickly, needing Shoto’s soft mouth back on his pussy. He grabs Shoto’s hair and leads him back to his clit so he can grind on his tongue.
Shoto allows himself to be positioned and then quickly runs his fingers through Katsuki’s slick before gently pushing into his pulsing hole. They both moan at the action. Katsuki because Shoto’s fingers are longer and thicker than his so they fill him more and reach deeper. Shoto because Katsuki’s tiny cunt grips his fingers like vice and his slick turns even sweeter. The inside of Katsuki’s pussy was so hot and velvety, squeezing and sucking at Shoto’s fingers, and it drove Shoto a little insane.
He plunges those two fingers into Katsuki’s cunt hard and fast, copying the motions that Katsuki had used on him earlier. Katsuki fucks himself on Shoto’s fingers, eyes rolling back as Shoto’s mouth sucks and slurps up his juices. It doesn’t take much more for the blond to cum. Shoto’s fingers hit deep and rub up against the perfect spot and he’s gone – moaning and shaking with the force of his orgasm.
With a wet pop Shoto pulls off of Katsuki’s pussy and watches as his fingers sink into that tiny little hole.
“Yes!” Katsuki moans, “F-Fuck, keep fucking me. Just a little harder– ngh , yeah … right there, oh fuckfuckfuck,”
Katsuki feels the pleasure slam into his body violently. Shoto’s fingers hitting just right inside him over and over until he’s squirting hard. Drenches Shoto’s whole face in his squirt and the other omega just seems to fuck him harder. Tears leak out of the corners of Katsuki’s eyes and he lets himself sob out more moans.
“You look gorgeous Katsuki,” Shoto said quietly, watching him in awe. “Taste amazing too,”
The last part is said right against Katsuki’s cunt. Shoto lightly runs his tongue over the sticky mess of Katsuki’s clit. Licks up a thick string of slick off his pussy and Katsuki’s fingers immediately pull at Shoto’s hair. God his pussy was so sensitive but it still ached with need. His heat already getting him ready for more. So Katsuki growls and forces himself to move.
He pushes Shoto so his back is once again pressed into the nest and straddles his face. Lowers himself down onto that waiting mouth. Arms snake around his waist and hold him down firmly so Shoto can lick up all that slick and cum and squirt. Katsuki’s pretty sure that Shoto was pussy drunk off his slick from the way he moans at the taste of Katsuki’s cunt.
But pussy drunk or not, Katsuki still plants his hands above Shoto’s head and rocks his hip against that soft tongue. Grinds his pussy on Shoto’s face nice and hard because Shoto’s nose is rubbing just right against his clit and that cool tongue is snaking its way into his tiny entrance once again. Already Shoto was improving his pussy eating skills and was flexing his jaw just right when he pulled out his tongue to click over Katsuki’s clit.
Their combined scents of cum and squirt was starting to get to Katsuki’s head because it smelled like sex and gooey marshmallows and spicy sweet tea and an overall rightness. It had the blond omega burning up with need and desire. Had him fucking his hips against Shoto’s face until he was shaking and crying out.
“Almost there,” Katsuki moans and Shoto echoes it back. Pulls Katsuki down onto his face even more. And then Katsuki has a great idea. “Fuck, Shoto … can you– ah, c-can you use your quirk? In your mouth?”
“How?” Shoto breathes out as he parts from Katsuki’s dripping cunt long enough to get the question out. His voice sounds wrecked and fucked out and then wet as he dives right back in, his mismatched eyes glancing up at Katsuki with lust.
Katsuki feels his hole clench and his clit throb at the look, “Make your tongue colder – just your tongue,”
It takes a moment, but Shoto finally concentrates enough to turn his tongue almost ice cold and the effect is immediate. Katsuki screams as he cums. Legs trembling violently as he continues to fuck his little clit onto Shoto’s cold tongue, grinding against it and Shoto’s face. Then Shoto’s fingers are making their way back into his cunt. Fucks him hard while licking over his clit and Katsuki’s thighs squeeze around his head as he squirts.
“Fuckfuckfuck , oh my god, oh f-fuuuck,” Red eyes roll back into Katsuki’s skull as he finally stops moving and just convulses in his orgasm. Shoto is lovingly and eagerly slurping down Katsuki’s slick. The sweet taste coating his tongue in cinnamon and caramelized bananas like Katsuki’s pussy was some kind of dessert.
Katsuki has to physically pull himself away from Shoto’s mouth when he finally stops cumming. His fucking lips were glued to the other omegas cunt like he needed it to survive. With a sparking hand pressed into Shoto’s throat Katsuki finally pulls his soaked pussy away from that sinful mouth. Shoto looks absolutely deranged with Katsuki’s mess all over his face and it gets worse when Shoto shoves his fingers into his mouth to lick up the fresh slick from his fingers.
An obscene moan comes from Shoto while he sucks off his fingers. He’s basically giving them a fucking blow job at this point an Katsuki growls at the sight. Rips those fingers out of Shoto’s mouth, moves himself down to lay on top of the omega, and licks up his own slick from Shoto’s chin before meeting his lips in a kiss. It’s filthy and wet, their tongues swapping Katsuki’s slick and squirt between them. Katsuki cleans up Shoto’s face with his tongue, feeds that sticky mess into Shoto’s mouth, and kisses him deep.
They finally break apart when Shoto’s face is clean and Katsuki knows that the heat has fully consumed them both when they can’t keep their hands to themself. Any clothes that were still on get ripped off – shredded for even daring to be covering up any skin. Shoto’s mouth is quickly searching for Katsuki’s again but a hand tangles in his hair and pulls him towards Katsuki’s neck instead.
Shoto gets to work, sucking hickeys into the soft skin. Bites into Katsuki’s throat with his rapidly sharpening omega fangs and then works his way towards that sensitive scent gland. Having lips and tongue and teeth working over his scent gland has Katsuki’s mind swimming. That damn mouth was too fucking much. He needed it in another spot. So he yanks Shoto’s head back, drinks in the whiny little noise he makes, and then shoves his head down towards his chest. Presses Shoto’s head towards one of his nipples and groans out when Shoto latches on.
Tongue switching between hot and cold, Shoto works it over Katsuki’s nipple until its a stiff peak – puffy and red. He abuses those cute little nipples because Katsuki keeps making the sweetest high pitched moans. They almost sound like sobs when Shoto’s teeth graze over them lightly and it makes slick rush from Shoto’s own pussy. He squirms, rubbing and squeezing his thighs together to get some type of relief but it’s not enough. Shoto whines against Katsuki’s chest and grabs the blond omega’s hand and places it between his thighs.
“More,” Shoto moans, forehead resting against Katsuki’s chest as his hips roll over those soft fingers.
Katsuki growls and takes his hand away from Shoto’s pussy. Places his hand on the dual tone haired omega’s thigh instead and pins it against the nest before situating himself over Shoto’s non pinned leg. Shoto watches with curiosity as Katsuki lowers his hips down until their cunts meet in a soft kiss. The first wet slide of their pussies has them both moaning, eyes rolling back as Katsuki finds a quick rhythm.
It’s so fucking wet and sloppy. They’re both leaking slick all over each other, rubbing their scents into each other and mixing them like a claim. Katsuki was losing his mind over the way that Shoto’s clit was so much bigger than his. It was so easy to grind against. Poked at his little hole with every thrust and it was making his insides ache in need.
One of Shoto’s hands pulls Katsuki’s face down towards his, kisses him in between panting moans and tangles their tongues together. The other hand grips Katsuki’s hip and uses it to roll their hips together better. He can feel the way that Katsuki’s tiny hole keeps trying to suck at the tip of his clit and the sudden urge to fuck into the tight space sets his body on fire. To have Katsuki, such a proud and aggressive omega, under him and rocking his hips on to his clit like a dick was a wild image in Shoto’s head. It drives him into using both of his hands to wrap around Katsuki’s small as fuck waist and roll them over in the nest.
Finally on top of Katsuki once again, Shoto takes in the way the blond omega’s cheeks are flushed the cutest shade of red, his hair is a mess, lips swollen and cherry red, eyes blown out in lust, and fuck he just leaked more slick. Shoto makes sure Katsuki’s legs are spread nicely before he lines up their pussies again and grinds down into that messy tiny cunt.
“Katsuki,” Shoto moans, “You feel so good. A-Am I doing this right?”
“Mhm, doing just perfect baby,” Katsuki replies breathlessly. His hands grab onto Shoto’s waist and help him rub against him. Loves how it feels all creamy and sticky and makes the most obscene sounds.
Shoto’s hips grind harder under Katsuki’s guidance, “Fuck … wanna fuck you. Please Katsuki, please your pussy feels too good. It’s so warm, your tiny hole keeps trying to suck me in,” The red and white haired omega’s cheeks flush while saying that, while begging to fuck Katsuki, but he can’t help it! Katsuki’s cunt was amazing.
The plush little thing felt so soft and silky against his own pussy. Warm and wet and grippy, just begging to be fucked open and Shoto needed to push his clit into that hole so badly. He can feel the shiver that goes through Katsuki’s body after he asks and it only encourages him more. Katsuki wasn’t sure where the hell Shoto learned to talk like that, can’t tell if the other omega had been reading some filthy shit behind closed doors, had an overactive imagination, or was just blurting out the most obscene shit without a filter. It was probably the last one, and that was worse because it made his pussy throb knowing that Shoto’s raw thoughts were that he wanted to fuck him.
Katsuki whined a bit, spread his legs some more and bit his lip as he gave a small nod. Now – during his heat – was the only time he’d let this candy cane fucker see him so flustered and vulnerable. And the cute, endearing, subtle show of submission had Shoto growling and sliding himself a little further down to smash his clit against Katsuki’s needy hole. Shoto presses, and presses, until he breaches that tight entrance.
Immediately, Shoto feels dizzy. Katsuki’s cunt sucks in the tip of his clit so fucking good it’s insane. It’s a pathetic display as Shoto whines and ruts into Katsuki’s hot little pussy. They’re both at the edge of orgasm, barely a few thrust of Shoto’s clit inside Katsuki and they cum together. Lips meeting to kiss and moan into each other's mouths as they cum.
Shoto continues to fuck into Katsuki with trembling limbs and gushing slick and cum all over the place. He’s so overly sensitive but his hips won’t stop. “Good … so good, hnnn … Katsuki, Katsuki,”
“Shit … fucking hell,” Katsuki voice is high, body shaking from his still ongoing orgasm and the way Shoto’s slamming his hips against his. Shoto’s drooling from how good he feels just taking and taking from Katsuki’s tiny cunt, and the nonstop stimulation has Katsuki rolling right into another orgasm.
He gasps out a moan, pussy slicking up Shoto’s clit and pouring down his thighs onto the nest and soaking into all the material there. His nails are starting to dig into Shoto’s hips because the omega is still fucking thrusting and grinding against him. Still moaning and drooling and forcing them both to cum over and over again. Katsuki can’t even push at Shoto because his body is just locked in wave after wave of pleasure.
When he rolls into yet another orgasm that has his mouth dropping open in a silent scream, the tears start to run down his cheeks again. Katsuki takes a gasping breath, swallows down the spit and drool that was building in his mouth and finally makes a wrecked garbled up sound. Shoto refocuses on Katsuki, heat clouded eyes blinking for a moment to take in the blond omega.
“Pretty,” he mutters out.
Katsuki blushes down to his neck but finally manages to slap at Shoto’s waist, “S-Stop! You’re gonna fucking kill me with orgasms, Halfie,”
Slowly Shoto pops his clit out of Katsuki’s hole and they both shiver at the exit. It wasn’t like Shoto was that deep in him or anything, but the connection was still felt throughout Katsuki’s whole body thanks to his heat. But his hole ached for something bigger.
The two omega’s kiss again to cool down from the back to back orgasms. Katsuki slips his fingers into Shoto’s hot cunt because he was still too squirmy. Only settled down when Katsuki plunged two fingers deep into him and fucked his pussy nice and slow. But it wasn’t long before that familiar throb in between Katsuki’s legs became an incessant blaring alarm in his body. And by the way Shoto was squeezing around his fingers and his whines were getting more frequent, Katsuki knew that Shoto was in need of being filled up too.
“Fuck … okay. Hold on,” Katsuki spoke, “Need to get something,”
Shoto made a dissatisfied noise at Katsuki moving away from him but didn’t try to stop him. He was curious about what the other omega needed to grab. It took less than a minute for Katsuki to pull out a box from underneath his bed and open it, grabbing something long and pastel orange and … Shoto gulps as he realizes what it is. It’s a toy. More specifically, a doubled ended knotted dildo.
The omega inside of Shoto was clawing at the surface, pussy slicking up and dripping all over his place in the nest, scent sweetening, and his insides tightening painfully. Shoto leans back against the nest and spreads his legs for Katsuki in submission. Glossy abused pussy out for display and Katsuki growls looking at it.
A perfect little pussy to get wrecked by Katsuki. He can hardly breathe looking at the way Shoto’s cunt flutters around nothing but air, hole pushing out more slick as the omega whines. Katsuki makes his way over to Shoto, he slowly runs the dildo over those soft, wet folds getting one end soaked and ready. Shoto rolls his hips back onto the toy, trying desperately to get it inside of him. His bottom lip is sucked up between his teeth as he watches Katsuki trail the toy over Shoto’s trembling pussy.
“Look at me,” Katsuki growls.
Pretty gray and turquoise eyes snap up to meet red eyes at Katsuki’s command. The dildo presses against Shoto’s soft little hole and slowly sinks in. Katsuki drinks in the way that Shoto’s eyes grow dazed, pupils dilating and mouth dropping open in a drooling moan as the toy fills him. Even through just pushing the toy inside, Katsuki can feel how tight Shoto’s cunt is holding onto it. Hungrily sucking it in right up until the knot.
Shoto groans and rocks his hips against the fake knot and whines and whimpers. “Please,” he moans.
Katsuki smirks, “Don’t worry I’ll give you my knot in just a second baby,”
The words have Shoto’s eyes rolling back as he cums around the toy. It’s so fucking hot watching Shoto cum, Katsuki doesn’t think he’ll ever get tired of watching it. Poor Shoto’s limbs are just weak little noodles at this point. Katsuki on the other hand, easily raises himself up, positioning himself over top of the other end of the dildo. Runs his fingers through the mess between his legs and coats the toy before sinking down on it.
His cheeks flare red as he holds in the scream he wants to make at being stretched so much. His tiny cunt getting split open felt so fucking good. As he takes the dildo deeper, it starts to push the knot against the rim of Shoto’s hole. Has him hiccupping out sobs as he scrambles to hold his legs open more for Katsuki.
“K-Katsuki! Pleasepleaseplease, oh my god, please!” Shoto whines. “Knot!”
Finally, Katsuki sits himself all the way down on his half of the dildo. Sinks down on the knot that his pussy so desperately wanted. Pulsing squeezes and aches in his cunt calming down now that there was a knot nestled in his pussy.
“Fuckin’ greedy little omega,” Katsuki grunts, feeling the way that Shoto can’t stop squirming on the toy. “Already addicted to cumming, aren’t you baby?”
Shoto nods his head, not paying any attention as he pushes against the toy, trying to stuff his pretty cunt with that knot. Katsuki grins wickedly and grabs onto Shoto’s legs tightly before thrusting deep into Shoto’s cunt. The knot slams into Shoto violently and makes the omega scream out. He squirts immediately. Gushes around the fake knot and tilts his head back exposing his neck. Katsuki wastes no time sinking his teeth into the soft porcelain skin and leaving more marks. Finds his way to that sensitive scent gland and abuses the area with lips and tongue and sharp omega fangs while he fucks into Shoto’s squirting pussy.
The pace Katsuki starts is harsh and quick, just chasing orgasm after orgasm. His own cunt was getting rubbed raw by the knot inside him but nothing felt better than their wet little cunts kissing with each thrust of Katsuki’s hips. Shoto’s clit brushing against Katsuki’s tiny one and giving them more friction. When Shoto finally comes down from his squirting orgasm he locks his legs around Katsuki’s waist, hands grabbing at Katsuki’s ass and forcing them closer together, pushing the dildo deep into both of them.
Katsuki moans as Shoto’s hips start to thrust back and fucks the toy deeper into his little cunt. It rubs against his walls, hits that sweet spot over and over again, and pushes at his cervix just fucking right. Katsuki cums with a shaky breath and captures Shoto’s lips in a kiss. They kiss sloppy and open mouthed, tongues tangling up in their moans and pants.
Never once do their hips stop meeting each other even as they shake and tremble through the motions. The only thing they could think about was cumming over and over, again and again, until they physically couldn’t anymore. The overstimulation burned so good, left them in a heated daze that just got worse the more they came. An insatiable appetite deep in the pit of their stomachs for that knot to fill them up.
With a wet smacking sound, their lips part. Katsuki leans back until his hands are planted on the nest and he fucks into Shoto’s cunt some more. Drool running down his chin and legs slotting themselves between each other so the toy gets completely swallowed up between their cunts. They grind and hump and fuck back onto the dildo just to make their slick clits kiss.
“Don’t stop … Please don’t stop! Feels so fucking good . Please Katsuki, more~” Shoto moans deliriously.
“Fuck … Take my knot so well, Shoto. Take it like the good little omega whore you are,” Katsuki growls and slams their hips together harder.
Shoto’s hands are gripping the side of Katsuki’s tiny waist, nails digging into flesh with the need to claim and mark. The wet sound of their cunts was driving them both crazy. If the puddle of slick forming under them and soiling the nest wasn’t clue enough, the loud lewd sound of their messy little pussies kissing and grinding and sucking in that toy would definitely alert them to how fucking wet they were. Strings of their thick slick stuck to each other's pussy and thighs and stretched out every time they pulled back from the dildo just to sink back down on it and mix their juices together once more.
Katsuki’s hands spark as he grips Shoto’s leg sandwiched between his own and grinds them together harder. Shoves that fake knot so deep in Shoto’s cunt that he can see the slight bulge it makes in his stomach. Shoto stutters out a moan at the little heated pops on his skin and grips Katsuki tighter.
The poor dual toned omega was just barely hanging onto his sanity. Heat fogging up his brain as he begged to be pushed over the edge once more, “Yes, please! Pleasepleaseplease want your knot! Katsuki! Katsuki! Please, I’m gonna–”
His broken and hoarse voice cuts off as Katsuki’s hips thrust just right over his sweet spot and smashes the head of the toy into his cervix, their clits grinding up against each other and Shoto can feel Katsuki’s starting to tremble too. They both crash over the edge at the same time, both squirting as they sit fully on the toy, pussies pressed together.
Screaming moans ring throughout the room. Wet squirt and thick slick pour out of their holes over everything, making them sticky and messy, mixing with the sweat covering their bodies and their hips are still lightly twitching and pushing back on each other as they both see white. Katsuki swears this was the hardest he’s ever cum in his life. It’s painful and so goddamn good it’s making him lose his mind. His ears are ringing, body convulsing with the force of the orgasm, and with both of them still pressed together his poor fucking clit is damn near burning.
He barely even registers the way his hands are sparking and lightly burning his own handprints into Shoto’s skin. Barely realizes Shoto’s hands are doing the same, though one side is burning a light handprint and the other is icing it into his skin. It takes a while for both of them to calm down. Their harsh breathing evening out after a while. Katsuki can only stare up at the ceiling, blinking his eyes so that his vision isn’t so fucking blurry. The first wave of his heat had finally been slated and the same seemed to be true for Shoto.
Just thinking about the intensity of this first round was making Katsuki’s skin hot. Another few days of this is going to leave him so fucking wrecked. He gets up on shaky limbs and slowly, and carefully clenches down on the toy so he can pull it out of Shoto’s ruined and abused cunt. A flood of slick leaves with it and a choked out moan from Shoto’s mouth. Once it’s out of Shoto, Katsuki relaxes his own pussy to let the dildo slip out and onto the nest.
Katsuki looks over at Shoto who’s still regaining himself and feels his heart flutter a little. Shoto looks so fucked out, every part of him is flushed, splotches of red and purple hickeys and teeth marks litter his skin, handprints bruised and burned into him, lips swollen from kissing and licking and biting, eyes dazed, and cunt fucked open and swollen and red from use. He looked perfect.
“God … stupid fucking pretty boy,” Katsuki mutters to himself before fisting Shoto’s throat and kissing him.
Shoto moans softly into Katsuki’s mouth as they kiss. As dazed as he is, Katsuki has to give him props for kissing back as much as he does. When they part, Shoto blinks up at him, all cute and innocent.
“You think I’m pretty?” he asks quietly.
Katsuki flushes, “Shut up, Halfie,”
“I liked it when you said my name. When you called me Shoto,”
“Stop it! You didn’t hear me say shit,”
“But–”
A hand slaps over Shoto’s lips, “You didn’t. hear. shit. Now I’m gonna grab us some water and we’re gonna take a fucking nap,”
Shoto nods his head and Katsuki removes his hand from the omegas mouth. He very slowly shuffles over to the mini fridge and grabs out two bottled waters for them before Shoto speaks again.
“... I really do like it when you say my name Katsuki,”
Katsuki nearly blows up Shoto’s water bottle.
When Katsuki and Shoto’s heatshare is over they both look like they got fucking mauled. Their scents seem to be tied together and everyone in the dorm can’t help but notice how much the two omegas linger by each other. They're much more touchy than before. Sometimes Shoto will seek out Katsuki for a cuddle or sit in his lap while the blond makes a fuss but ultimately wraps his arms around the other omega’s waist and buries his nose in Shoto’s scent gland.
It’s no surprise when other students find the two of them making out on the dorm couches right before their heats. The two omegas are so engrossed in each other’s mouths that they don’t register anything else around them. Only when the two are physically pulled apart do they turn their heads and growl at being disconnected. Still they make their way to one of their rooms and Katsuki does his absolute best to corrupt Shoto’s sheltered little omega mind every time they heatshare.
And maybe during one of those heatshares Katsuki sneaks in a little whispered confession of having a crush on Shoto and the omega whispers the same back.
