Work Text:
It was the weekend before Halloween so it was granted that the streets were packed to the brim with locals and foreigners, the stores were full of candy bags and costumes with people going in and out with handfuls bags of alcohol and candy, all the while cops were roaming the streets to keep an eye on anything suspicious.
Halloween was also a perfect time for Izuku to go out and let loose while simultaneously dressing like a whore without being judged before he turned into a sweet innocent boy for Christmas so his mother didn’t suspect a thing. If she ever saw her perfect omega son dressed like this, she would have an aneurysm, die, come back as a ghost and haunt Izuku for the rest of his life.
But to be fair, Izuku hardly dressed like this and his wardrobe only consisted of corny shirts, sweatshirts, and baggy jeans so when the time did come for Izuku to dress up—he dressed up. Even though he mostly sat at the bar sipping on his fruity cocktails and making sure his friends were safe from any weirdos, it was fun to be able to dress freely without being judged.
Now was a perfect example of being judged, Izuku cleared his throat and tugged at his white pencil skirt ignoring the dirty looks he got from the older men and women on the train; having given up his seat to a pregnant omega, Izuku was holding onto the railing beside her and scrolling through his phone aimlessly, occasionally shifting and fixing his skirt whenever the train would stop, doing his best to ignore the heated gaze from the Beta standing across from him.
Izuku almost sighed in relief when his stop was called through intercom and the train slowed to a squeaky stop, there was a slight pause before suddenly the doors opened and Izuku was the first one out considering the doors opened up right behind him and he hightailed it out of the lower platform towards the stairs. Izuku hurried up the steps of the station, holding his skirt down in case he accidentally flashed someone and it was just his luck that the outfit he ordered online ran in smaller than he expected or he forgot the extra volume he carried on his lower half.
The white shimmery pencil skirt was tight with tiny slits on each side, the skirt should’ve stopped mid-thigh but unfortunately considering his heavier bottom half, the skirt hiked up higher than he expected so now he was in fear of getting arrested for accidentally flashing someone, on top of that the tights he got for the skirt had ripped midway while he was putting it on. So now he was late because he was rummaging around his room trying to find something to match and instead all he got were some white knee-high socks he bought on a whim cause they were on sale.
Thankfully that did the trick covering up his legs but just up to knees, he was still freezing his ass off, literally. The top of the costume was a sleeveless white ribbed crop top with a heart cut-out for his cleavage, despite being a male omega his tits were smaller than average so he never even bought regular wired bras aside from sports bras or bralettes.
Izuku's mind was a mess because of his tights incident and he was running even more behind that he forgot the white bralette he laid out beside his top and grabbed his coat and hightailed it out of his apartment. Adding to his horrible luck, he had somehow left his jacket while connecting to another train and now here he was in the middle of downtown with no means to protect him from the October cold on top of that the Beta had followed him out and Izuku did his best to ignore him by pulling out his phone and staying near the station in case he had to make a run for it.
“Hey,”
Blinking, Izuku looked over to see a Beta smiling at him, managing a quick smile Izuku straightened up watching him warily. “What’re you doing out here in the cold?” he asked, Izuku continued with his fake smile and he waved his phone, “Waiting for my boyfriend,” he said quickly watching the Beta’s reaction and it was not much of a surprise when he saw a flash of irritation in his brown eyes before calming himself.
Izuku hadn’t expected the beta to start a conversation, most of the time Beta’s would stare for a bit and watch him before getting bored and leaving, it was usually Alpha’s Izuku had to worry about.
“Really? I wouldn’t let my partner wait out in the cold like this, especially dressed like that,” he said, his eyes drifting down to his chest and looking around, “Practically a fresh piece of meat in this street right now,” he said.
Izuku glanced down and to his embarrassment, his nipples were hardened and poking through his ripped sweater, worst of all he hadn’t noticed how sheer his top was and anyone could practically see his pink areola. Izuku really hated his luck, maybe he should've been a good boy and stayed at home like his mother told him to.
Crossing his arms to protect his exposed chest and without realizing he managed to perk up his breast more, “My boyfriend should be here soon,” Izuku said firmly but that didn’t seem to the do the trick, most Alpha’s laughed whenever Izuku would pull the fake boyfriend move, calling him cute or whatever lame compliment they gave him until Izuku had to bare his fangs for them to leave and it looked like the Beta was about to do the same thing, he let out a tiny laugh and started to unzip his jacket.
“Here, look I’m just trying to help, take my jacket and I’ll wait here till your boyfriend comes along, how about that?” he said already shrugging off his jacket, Izuku shook his head and took a step back, “N-no it’s alright, sorry my boyfriend gets really jealous and possessive,” Izuku lied between his teeth.
Izuku prayed that his phone would buzz or that his date would show up somehow to save him from this disaster. He knew he should’ve gone to the station’s bathroom to wait or find a cop so he could report the creepy beta.
The beta didn’t seem to like that answer and the grip on his jacket tightened, “That’s very toxic of your boyfriend, he would rather let you freeze than take on an offer from a kind beta? I’m not trying to do anything but help,” he said, his voice louder and more assertive.
“I’m fine really! He should be here any minute,”
“Take the jacket, I'm just being a nice guy."
Swallowing, Izuku racked his brains on what to do, his fight or flight instinct was really kicking in and his entire body told him to fight, just as he was about to argue back Izuku saw a flash of familiar blonde spikes just beyond the Beta standing near the curb in all his glory.
Decked in all black except for his leather maroon racer bomber covered in patches, he wore his wire headphones around his neck and was aimlessly scrolling through his phone. Heart racing, Izuku almost cried in relief and he stepped to the side ignoring the confused look the beta was giving him.
“K-Kacchan!” Izuku called getting up on his toes and started waving his hand trying to get Katsuki’s attention, sure enough, Izuku could see Katsuki perk up and look around before those red eyes that haunt Izuku every night land on him and he could see the confusion on Katsuki’s face before settling in with annoyance.
The beta who was originally facing Izuku turned to face Katsuki with a frown and in that moment Izuku took his chance, his eyes widened in panic and he mouthed help to Katsuki while waving him over frantically. Izuku could see the exact moment Katsuki clicked everything together, a scowl slipped on his face and he started to walk over while shoving his phone in his pocket and wrapping the headphones around his fist shoving them in his pocket as well.
Izuku had never been so grateful in his entire life and when the Beta turned back around to face Izuku, the jacket still in his hands, the Omega couldn’t help but smile at him smugly. Heart racing, Izuku squeezed around the brown haired beta not even bothering to excuse himself and only managed to take a couple of steps forward when Katsuki reached him and Izuku quickly latched both of his hands around Katsuki’s one hand and frowned up at him.
“Kacchan! I was waiting for you!” Izuku whining forcing a pout, the blonde raised an eyebrow at him and his eyes flickered behind at the Beta; it didn’t take long for Katsuki to realize what Izuku was planning and the hand sandwiched between Izuku’s tightened and tugged him forward, making Izuku stumble forward with a tiny ‘oof’ and land against Katsuki’s chest, his tiny breast squishing again Katsuki’s hard muscle.
There was a low rumble coming from Katsuki’s throat and for a split second Izuku wanted to chirp back and bare his throat but he knew that it would get him into more trouble than he was now and instead he took a half a step back so he wasn’t shamefully pressed against Katsuki like that.
“Hey baby,” Katsuki rumbled, moving his hand and settling it on Izuku’s bare lower back, his heavy hand searing into Izuku’s cold back and Izuku’s brain almost went to mush when he felt Katsuki’s thumb gently caressed his tender skin in a soothing manner. A shiver traveled down Izuku’s spine sending goosebumps erupting all over his body and he flushed bright red, hoping Katsuki would blame the cold for Izuku’s shiver.
Swallowing, Izuku pressed a shaky hand on Katsuki’s stomach feeling it tense up and Izuku turned to glance over his shoulder at the Beta with another smile this time less smug because he was trying not to freak out when he felt Katsuki’s hands just barley dipped under the fabric of his skirt, gently teasing the soft skin of his lower spine.
“Thanks for keeping me company,” Izuku said sweetly, the beta was quiet for a moment and Katsuki took that chance to slide his hand down so it settled on the curve of his butt possessively and gave his ass a few firm taps and Izuku felt the blush rise up in his cheeks, squirming against the touch.
“ This is your boyfriend?” The beta questioned looking at Katsuki, it was the wrong thing to say because Katsuki cupped his ass tightly and yanked him back against him. Izuku’s startled squeak was ignored by both of them, “You gotta a problem four-eyes?” he demanded.
The beta shook his head and raised his hands, “No–I was just saying cause you two don’t smell like each other or smell mated,” he said, he sounded suspicious and it was suspicious. Izuku quickly looked over his shoulder again, “We’re recently just started dating so I wanted to take things slo—”
“—Fuck off you freak, what me and my damn boyfriend do ain’t none of your business!” Katsuki snapped, Izuku quickly clamped his mouth shut because now he made it seem more suspicious, gosh he was so stupid.
“Woah hey, I was just concerned for the omega, he was left all alone in the cold, I was just helping him”
“Thanks for the concern glasses, but it’s not needed,” Katsuki said coldly, “We should get going, c’mon” Katsuki said not bothering on waiting for an answer and with a hand still on his ass, he guided Izuku away from the creepy beta and down the busy road trying to blend in with the crowd. Taking large steps that Izuku had to half jog and half walk to keep up, it didn’t help that his skirt kept rising so he had to use one hand to hold onto the bottom of the skirt while trying to match Katsuki’s pace.
Once they were further away, Katsuki yanked his hand away from his ass and before Izuku could get offended, he grabbed Izuku’s hand so he didn’t fall behind in the holiday crowd.
“How the fuck do you always end up in these kind of situations!” Katsuki hissed, his eyes still trained in front of him, both of them could easily smell the creepy beta following them, keeping a safe distance so it wasn’t at all suspicious if you were an outsider looking in.
“How are you blaming me!” Izuku snapped back, “And slow down! I can’t keep up and I’m freezing!” Izuku panted, he almost tripped twice the entire time and his nipples were so hard against his top, he was sure they would poke a hole through the fabric and it wasn’t pleasant getting stared at by the passing crowd.
“Goddamit,” Katsuki snapped, pulling Izuku to the side where he was able to take off his jacket, holding it out for Izuku to take and he didn’t argue. Instead he quickly slipped it on with a deep sigh, snuggling into the heated leather jacket. The jacket was soaked in katsuki’s charcoal scent and it was confronting like a summer night.
“Also, where the fuck is your jacket, now wonder the creep cornered you when you’re walking like that! ”
Izuku refrained from stomping his feet and glared up at him, “I forgot my jacket on the train, can you stop blaming me and besides it’s halloween , I normally don’t dress like this!” Izuku snapped, waving his hands over his body and he resisted the urge to squirm when Katsuki’s eyes roamed his body, pausing before flickering back towards his face.
“I know. Why the fuck are you dressed like that anyways,” he demanded.
Izuku crossed his arm and glared at his feet, “Like I said it’s halloween and I’m supposed to be an angel,” Izuku muttered and at that Katsuki snorted a laugh leaning back against the wall, “Yeah? So where’s your wings and halo?” he asked and that had Izuku shifting awkwardly, “I also forgot them on the train,” Izuku mumbled, making Katsuki huff out a short laugh that had Izuku flushing harder.
“I’ll call a cab okay, can you just wait till it arrives and then I’ll be out of your hair,” Izuku said with a defeated sigh and lifted one flap of the jacket so he could reach for his phone, he heard Katsuki clear his throat and when he looked up to see the blonde’s ears were pink.
“Don’t be an idiot, it’s safer to stay with me then leave, the fucker could easily follow you in another taxi,” Katsuki said grabbing Izuku’s phone from him and tucking it in his own pocket.
“Hey!”
“And zip yourself up! Jesus, you’re flashing everyone!” He added waving his hand in front of Izuku’s chest. Embarrassed, he quickly folded the jacket over his chest not bothering to zip it up.
“Where were you going anyways, I’ll walk you,” Katsuki said, running a hand through his hair. Izuku sighed and asked for his phone back to which Katsuki reluctantly gave it back, watching Izuku pull up an address and held the phone in Katsuki’s face.
“Don’t go shoving your phone in peoples face,” Katsuki snapped, grabbing the phone from Izuku’s hand and zoomed in and out on the map with a frown, his eyes scanning the light up screen.
“It’s this bar that’s doing a halloween night, Uraraka-san asked me to come—we were supposed to go together ended up going with her girlfriend,” Izuku mumbled and Katsuki wrinkles his nose at the statement seemingly judging Izuku for his lack of backbone.
“Cheeks got a girlfriend?”
“Yeah they met at this vampire themed bar or hopefully it was a themed bar, some people were very serious into their roleplay,”
“...why were you at a vampire bar?”
“What’s the questions!?” Izuku demanded, his cheeks heating up again at Katsuki’s judgmental look, “Can you take me there or not?”
“Damn, calm the fuck down I’ll take you and why the fuck would she let you go alone,” Katsuki snapped, Izuku shrugged not knowing what to say when his eyes caught a familiar person leaning against bus stand, the beta wasn’t watching them but he was close enough to know he was definitely followed Izuku.
“Kacchan,” Izuku mumbled, stepping closer to the blonde who raised his eyebrow at him, “He’s right there,” Izuku whispered, his body going tense when Katsuki frowned and stood up straight. “Let’s keep walking,” Katsuki said, grabbing his hand and holding it tight and pulling them back into the crowd towards the direction of the bar.
The beta was persistent, not wavering once and his irritated scent kept growing stronger with each passing second and for some reason that scared Izuku, he would’ve thought that seeing Katsuki would scare him but the beta seemed more irritated than scared.
Most Alpha or Beta got scared of Katsuki and Izuku knew, he’s seen Mina use Katsuki to be her fake boyfriend multiple times whenever Kirishima wasn’t around.
“Can’t you beat him up!” Izuku whispered, sticking closer to Katsuki while they got stuck at a crosswalk. Katsuki’s lips twitched and his gaze flickered down to him for a second. “I thought you were all about peace and love,” he teased, making Izuku give him a dead panned look, “No when I’m being stalked! Besides you should be jumping with joy ready to beat an extra up, don’t you spout that shit all the time,” Izuku muttered then squeaked when Katsuki reached down and grabbed his cheeks squeezing them playfully forcing his lips into a fishy pout.
“You kiss your mother with this potty mouth, you taught you that word anyways,” Katsuki remarked and Izuku slapped the offending hands off him and glared up at Katsuki with red cheeks, “Stop acting all righteous when every other words that comes out of your mouth is a curse,” Izuku snapped.
“ Anyways ,” Katsuki started rolling his eyes and Izuku rolled his own, “The freaks a minor, do you want me to go to fucking jail for trying to kill a minor,” he said, quickly tugging him when it was safe to cross, “Trust me I would love to whale on that creep and I’m holding back on tossing his sorry ass onto the street.”
“Kacchan, can you please slow down and I’m not asking you to kill him! Just a punch or two—maybe three?”
“No and keep those stubby legs moving also I aint hitting a minor, damn Deku. I could be charged for assault even if he was stalking you, now if he was an Alpha the case would be different but he’s not,” Katsuki snapped, Izuku huffed and kept on toddling after Katsuki, his curls in a continuous bounce and his cheeks were so pink it looked like he had placed blush all over his face.
“I guess that makes sense, I kept wondering why you didn’t punch his face in yet,” Izuku muttered, Katsuki barked a laugh and tugged Izuku closer ignoring the squeak as Izuku jogged to keep up, “Seriously? You think I want to go around beating people up,” he asked.
“No!” Izuku snapped, it was a lie, he did. But who could blame him with how many times he saw the blonde ruffled up with a bruise on his cheek or his lip split, the blonde loved to fight like it was breathing. Must be an Alpha thing, Izuku thought curiously.
“That fucker is still following us,” Katsuki muttered, Izuku nibbled on his lower lip, “Should we call the police?” he wondered, the alpha shook his head. “You think the cops are gonna help us? Betas are second rank from Omegas that are the most protected by the government, that’s how they can easily fly under the radar. He can easily twist the situation around and have the cops believe him even if you vouch for me and besides—Do you really think a bunch of cops are gonna believe an omega dressed like a damn slut on a saturday night?” he said.
“You know this is not how I dress all the time!” Izuku whined, already getting irritated by his situation, “Besides, you’re here with me, what if you say something and they always believe Alpha’s anyways,” Izuku said hopefully but Katsuki ignored him.
“Hey!—Ow Kacchan!” Izuku gasped when Katsuki quickly pulled him into an empty dark alleyway, he stumbled after the blonde then squeaked when katsuki pushed him against the wall after they passed a large green recycle box, bracing a hand behind Izuku’s head and stepped into his space, looking down at him.
“Kacchan?” he asked again looking up, the blonde’s face was shadowed by the dimly lit street lamp and he watched as Katsuki’s red eyes darken and he leaned closer just enough for the tips of their noses to brush slightly and Izuku’s eyes fluttered, he could smell Katsuki’s heavy pheromones and he was so glad he remembered to wear his All-Might patches, otherwise he would rather brain himself if Katsuki could smell his slick pooling in his panties.
“Follow my lead,” Katsuki whispered, tilting his head down and lifting one hand to slowly unzip the jacket, exposing Izuku’s body little by little until the jacket was completely unzipped and pushed off his shoulder falling into a heap beside his white boots.
“...cold…” Izuku mumbled, then gasped when the hand behind his head slid down and cupped the back of his neck, his thumb pressing right against his scent patches, fiddling with the corners of it. Something so bold that not even an Alpha who was courting an Omega would ever dream to do.
Izuku lashes fluttered and let out a whine, that seemed to do something as Katsuki cursed quietly and grasp one of Izuku’s thighs in his hand, guiding the thigh up and around Katsuki’s own hip, he gently caressed the meaty muscle, his fingers deeping under the white pencil skirt. Izuku let out a breathy gasp, his plush lips parted in a silent ‘o’ showing off his cute pearly bunny teeth.
“You with me?”
“Uh-huh,”
“Good boy,” Katsuki breathed leaning down to let their breaths mingle, Izuku’s eyelashes fluttered and he didn’t even realize he was arching into the blonde, silently begging for him to keep going.
“Pinch me if I take it too far,” Katsuki warned and that was the only warning he got before he ducked down and kissed him. Izuku was ashamed at the moan he let out when their lips touched, but that was all the motivation Katsuki needed to keep going.
The hand around his neck tightened and Izuku hated how easily that made his knees weak, he hated how quick he was to get wet by such a simple act; he also hated how good of a kisser Katsuki was.
Kissing him like their lips were making love for the first time. If this was his first kiss, Izuku knew he would be spoiled because now he can’t imagine mating with someone who didn’t kiss like Katsuki. Izuku’s hands were hovering beside him before he put them on Katsuki’s biceps, twisting his fingers into the delicate sweater.
“ Mph, ” Izuku whined when he pulled back to breath only to be tugged back into another kiss, this time Katsuki slipped his tongue in that had Izuku’s eyes pop open and to his embarrassment, Katsuki was watching him with half lidded eyes.
Oh
His eyes were glowing red and his pupils were slitted, it was then that Izuku felt the sharpness of Katsuki’s claws that had emerged in the beginning of their kiss, gently scraping the sides of his neck making him almost cream his underwear, the soft sensation of Katsuki’s claws tickling his neck made his scalp tingle and his body squirm delightfully
Izuku pulled away with a lewd wet slick sound, he flushed all over and Katsuki chuffed at him, nipping at his chin, “Kacchan,” Izuku whispered breathlessly, he was panting and his lips were wet, his underwear was soaking, and he knew Katsuki would smell just how wet and horny he was.
“Shhh, just a bit more,” Katsuki said gently guiding Izuku back in for another kiss, Izuku closed his eyes and this time he looped his arms around Katsuki’s neck, dragged him close so they were pressed chest to chest with each other, he parted his lips letting Katsuki slid his tongue in. Izuku always hated the idea of someone’s tongue in his mouth, he would listen to Uraraka-san or anyone else talk about kissing and he always found it odd and icky to think someone’s tongue could be so erotic but Izuku took it all back.
Katsuki could hardly let him breath, his tongue stroked Izuku’s tongue, twisting around it playfully before up and trailing the tip of his tongue along the roof of his mouth sending tingles down down his spine and he whined pulling away just to breath but Katsuki was quick to keep yanking him back.
Each time was more desperate than the last, their kisses became messy and Izuku knew there was a drool coming out from the corner of his mouth but he couldn’t stop. It was like they were both waiting for this moment to happen for ages.
“Fuck baby,” Katsuki cursed pulling away to breath, this time it was Izuku who whined and pulled him back, swallowing the groan with a kiss. The hand on his thigh slid up towards his waist and Izuku’s leg dropped but Katsuki was quick to shove his knee between his legs making Izuku whine into the kiss, he pressed down on the blonde’s thigh pressing himself flush against the thick fabric of his jeans.
Izuku broke away from the wet and knocked his head against Katsuki’s collarbone, breathing heavily when Katsuki slide his leg back and forth, a muffled groan escaped him and he clutched tighter onto Katsuki’s shirt his own body swaying back and forth to match Katsuki’s leg.
“Ka– ngh –Kacch– Oh!”
“That’s it baby,” Katsuki cooed, cupping Izuku’s jaw and tilted his head back to kiss him, swallowing every desperate whimper that slipped back his lips, and the hand around his waist slowly slid up and he hadn’t even noticed that Katsuki’s warm hands slipped under his crop top until he cupped his tiny cold breast, pinching his nipple between his knuckles.
Izuku couldn’t help but roll his eyes back and break away from the kiss, panting heavily against Katsuki’s lips, he let out a croaky moan when Katsuki’s leg jolted up making Izuku bounce on his thigh.
“You like that?” Katsuki hissed, rolling the aroused nipple between his knuckles and Izuku whined, grinding down harder on Katsuki’s thigh, his slick completely soaked through his jeans. Katsuki snorted and he leaned forward to suck on Izuku’s tongue that had been slightly sticking out of his panting mouth and he continued to squish and fondle his breast, pushing up the fabric of his top to expose the one breast he was fondling.
“You want me don’t you Deku,” Katsuki teased, pinching the nipple and giving it a tug, his cock twitching in his jeans when Izuku arched into his hands, his eyes half lidded and watching him. “I can fucking smell you. It fucking reeks of arousal, I bet every unmated Alpha from kilometers away could smell your dirty stench,” Katsuki groaned and Izuku shook his head with tears brimming his eyes.
“M’not stinky,”
“No, you’re not. I was just being mean, but you like me mean don’t you?”
“Uh-huh,”
“ Uh-huh . Look at you so sweet and willing, fuck you smell so damn sweet. it’s making me lose my damn mind everytime I’m around you,” Katsuki snarled, twisting the pink nipple painfully and his body shivered at Izuku’s high pitched yelped and he resisted the urge to stomp his feet and howl like a deranged animal.
“Want me to fuck you Deku? I bet you would like that, right here in this alleyway like a goddamn slut,” Katsuki taunted, leaning down to suckle the nipple in his mouth while his hand switched to pinch and pull on the other nipple through the thin slutty fabric of Izuku’s top.
He felt Izuku moan and cup the back of his head urging him closer and who was Katsuki to deny such a sweet request. Sucking harder and swirling his tongue around the pebbled nipple, Katsuki held back a groan when Izuku moaned softly, twisting his fingers into Katsuki’s hair
Katsuki pulled away with a wet pop, gently nipping at the nipple and glanced up to see Izuku watching him with wide eyes, flushed cheeks, and parted lips. He looked so debauched just from having his itty nipples sucked but Katsuki wasn’t done yet, he moved the hand on Izuku’s lower back slowly sliding it around and under his fitted pencil skirt.
Grinning around the nipple between his teeth when Izuku let out a breathy moan as Katsuki’s fingers petted the soaked panties and he watched as Izuku’s mouth parted a bit and he whined his hips jerking against Katsuki’s touch. Pressing a soft kiss to his nipple, Katsuki moved back up to kiss the apples of Izuku’s soft glittery cheeks.
Katsuki pressed a finger against the swollen nub through the underwear and Izuku whined and squirmed away the pressure was too much and Katsuki wasted no time in slipping his fingers under the soaked fabric, his fingers gently fondling the wet folds while his thumb slowly circled the berry clit before pushing two fingers inside the heated cunt and Katsuki couldn’t help but watch, entranced as Izuku’s lips parted and a soft gasp escaped him, his body trembling at the sudden intrusion.
Katsuki himself felt like he was in heaven, Izuku’s cunt was slippery, heated and sucking in his fingers like a warm hug, “That’s it baby, slowly, shhh, don’t moan so loudly,” Katsuki cooed easing his middle and ring finger in and out of Izuku, crowding him into the brick wall and licked those pretty swollen lips.
“ Ah–ah—mmmh— ”
Stroking his fingers along the velvety walls, Katsuki held back a groan when Izuku clenched tightly around his fingers and his body twitching. Taking his time, Katsuki was captivated at who easily Izuku’s cunt sucked him in, his juices squirting around the fingers as they pumped inside him faster.
“Fuck you feel so good,” Katsuki moaned leaning pressing a wet open mouth kiss on the apples of Izukui’s cheek and kissing all the way down to his ear where he sucked on the sensative skin under his earlobe, “So pent up baby, when’s the last time someone fucked you this good? Or has no one got a chance in claiming this pussy? Am I your first baby?”
Izuku moaned in response his body jerking trying to ride Katsuki’s fingers, his eyes screwing shut and brows furrowing, open mouth panting against Katsuki’s shoulder but Katsuki was quick to curl his hand into those thick curls and yank his head back, staring down at Izuku with a mean smirk.
“Tongue out,” Katsuki ordered and even though it was a proper Alpha command, Izuku’s body reacted like it was, his cunt clenching around his fingers and Izuku’s green eyes darkened. If he looked this sex drunk, Katsuki couldnt imagine what he looked like once he actually fucked him with his cock.
Pretty pink tongue stuck out of those swollen lips, Katsuki could feel Izuku’s body tremble and jerk when he spat right on his tongue, groaning at the sight of his spit dripping backwards down his tongue further into his mouth.
“Christ, Izuku,” Kaatsuki hissed, tilting his head and swallowing the moan that almost escaped Izuku with a harsh and desperate kiss. It couldn’t even be described as a kiss but mostly a mess of saliva and tongues, Katsuki was quick to suck on Izuku’s tongue before aggressively kissing him again.
Izuku’s hand quickly came up and dug into his arms, his elongated omega nails latched onto Katsuki’s sweater and Katsuki hissed at the slight pain but that didn’t stop him, instead he fucked him harder with his fingers and circled the clit harshly with his thumb making an absolute sweaty mess of the omega under him.
Katsuki grinned, flashing his fangs while he watched Izuku almost unfold under him, seeing how quick his eyes almost rolled back but at the end of the day Katsuki was a cruel bully. He waited until Izuku was almost close enough before he yanked his fingers out of his cunt. Katsuki couldn't help but mock Izuku’s whine, shushing him teasingly.
“Oh baby, what’s wrong?” Katsuki cooed watching Izuku start crying out of frustration and he almost snickered when Izuku glared up at him pitifully, “You wanna cum? Fuck baby you know you gotta work for that. I did save your life so where’s my thanks? I can’t let you get everything you want,” he taunted. It bothered him to tease him because he desperately wanted to forgo the cruel act and fuck Izuku like a horn-dog he was but he needed to be patient.
“Wha?” Izuku mumbled, his brain finally catching up from being so lust drunk. Katsuki scoffed and he stepped back despite his Alpha ready to brain himself on the floor from denying his omega.
His Omega . Katsuki thought with a sharp inhale.
“I need you to beg for it, c’mon tell me you need me as much as I need you,” Katsuki sneered cruelty and to prove his point he unzipped his pants, shoving his pants and boxers down just enough for his cock to spring free and he swore the air turned thicker and Izuku’s pheromones were stronger.
“Beg for it Omega.”
Ecstatic, he watched Izuku shift nervously, his hand coming up to grip the hem of his cropped sweater There was a moment of hesitation while he rubbed his thighs together painfully being reminded of how desperately empty and horny he was.
A shiver went down his spine and a wicked grin spread across his face when he watched Izuku grip his top and push it up, just enough to expose his other breast with the top scrunched above his breast. They were perfect, tiny but pillowy and softly rounded with pink areolas.
Fuck this was good, the damn nerd was actually going to do it.
Katsuki thought, his cock twitched and he reached down to grasp it, slowly pumping himself holding back a groan when Izuku thumbed his pencil skirt, embarrassingly shimming out of the skirt and soaked panties. Awkwardly stepped out of it and left him in his two inch white boots and his knee high white socks.
The blonde sucked in a breath at the sight of Izuku’s body on display, he looked like one of those red distract whores that people buy out. Chubby shaved cunt, glistening with slick, thigh thighs that pudged out from his knee thigh socks, wide hips that went up to his thick toned stomach and his cute little belly button and the two perky breast, the best part he was pink all over and Katsuki wondered how did he get so lucky.
Katsuki almost came in his hand when Izuku leaned back into the wall and spread his legs wide, one hand going to spread his cunt lips with two of his fingers, “Please,” Izuku pleaded, “I need you, ‘m so empty, Kacchan,” Izuku begged and Katsuki swallowed licking his lips, his eyes narrowing on the sight of his pink flesh.
“What's the magic word,” Katsuki whispered, juicing the situation as much as he could. Izuku flushed and he panted desperately at him, shifting his legs wider, “Please Alpha ,” Izuku whined low in his throat and to top it all off, he tilted his head just slightly to the side.
Something snapped and Katsuki instantly loomed over Izuku blocking any sort of light raining down on him, he shoved a hand against Izuku’s neck squeezing it just shy of painful forcing the omega to blink up at him with wide tearful eyes.
“Katsuki, ” Izuku breathed his lashes fluttering, an fierce scowl spread across Katsuki’s face and he shoved his cock right on top of Izuku’s cunt, sliding the thick cock between those chubby wet lips and teased him watching the desperation easily leak back into Izuku’s eyes, his cockhead just barely brushing Izuku’s rim with each thrust.
“ Mmmh!” Izuku moaned, biting his lip and fluttering his lashes at Katsuki; he parted his wet lips and breathed his name again, “Please Kacchan, I’m so empty, want your cock,” he begged. Katsuki inhaled sharply, voicing a low curse and stepped back, ignoring Izuku’s confused whine.
Katsuki haphazardly grabbed Izuku’s wrist before twisting him around pushing him into the wall chest first and kicked Izuku’s legs apart so he could widen his stance. Katsuki paused for a second before grabbing his jacket from the floor and placing it as a protective barrier between Izuku and the brick wall.
“Oh,” Izuku mumbled, holding onto the jacket so his hands weren’t scraping against the wall, “Thank you,” he mumbled shyly as if he wasn't naked in a dark alleyway. Katsuki grunted adjusting the jacket so it laid flat on the wall, protecting Izuku's chest.
Katsuki grunted before fully admiring the fat ass in front of him, olive skin with a scatter of freckles all over, especially tiny brown ones all over the curve of Izuku’s ass. A groan escaped when he cupped the cold ass cheeks, massaging the fleshy muscle with gusto.
“Kacchan hurry,” Izuku whined looking over his shoulder at him, wiggling his hips and he almost got light headed by the side of Izuku’s ass jiggling back and forth, arching against his cock, “Be fucking patient,” Katsuki warned gripping his ass.
With his other hand, he aligned his cock right against the freckled cunt and slid in slowly, his head lulling back at the feeling of Izuku’s tight heat surrounding him, goosebumps erupting all over his skin and he shivered in excitement. Katsuki groaned loudly, his mouth dropping when he bottomed out, his hips meeting Izuku’s ass.
“Shit,” Katsuki cursed, taking in a deep breath. He was not about to cum like a pathetic loser on his first time, he needed to prove to Izuku that he was a capable Alpha. Cursing under his breath, Katsuki gritted his teeth and took heavy breaths to calm himself, one half wanted to go ham and jackrabbit into the omega but the other wanted to take it slow.
You’re in a dirty alley, Katsuki thought, there was no way to take this slow.
“B-big, so big,” Izuku gasped, his face was smoothed into his jacket, eyes wide and his mouth parted, his hand was clutching desperately onto his jacket. They both groaned when Izuku clenched his cock hard making his hips involuntarily jerk forward and Izuku cried out.
Katsuki swallowed and slowly drew back making Izuku whine low in his throat, his lashes fluttering shut as he did before he slammed back forward, his hips clapping loudly against Izuku’s cheeks making him rockward onto his toes.
“Gonna rearrange your guts,” Katsuki swore and with a hand to the back of Izuku’s neck, keeping him faced into the wall and the other gripping tightly onto Izuku’s ass cheek, he started a brutal pace and rocked Izuku’s body back and forth on his cock like a dumb cocksleeve.
Gritting his teeth, Katsuki glanced down at how easily Izuku’s cunt split open with his cock going in and out of him. Katsuki watched almost drooling on himself as he pulled out fully with only the tip of his cock kissing Izuku’s stretching hole, teasing the trembling cunt and sliding back in.
“Ah! Ngh! Kacc– mmh— Kacch ahn! ”
Sweaty bodies rocked against each other in a desperate attempt to gain pleasure in the cold winter night and Katsuki quickly moved his hand to cover the incoming scream from Izuku’s throat, clamping his large hand over his mouth with his thumb over the bridge of his nose.
“Sh-sh-shhh,” Katsuki panted, the last thing he wanted was for someone to hear his wanton moaning. The clapping sounds of Izuku’s ass and his hips were loud enough already. Katsuki closed his eyes and held back a groan when Izuku moaned into the hand covering his mouth, rocking back against Katsuki’s cock with his eyes screwed shut in pleasure and he could feel the heat build up in his lower stomach, he was slicking up so much that there was a small puddle between Izuku’s legs.
“C’mon baby, that’s it, shhh, I got you, Alpha’s got you,” Katsuki cooed swiveling his hips and the hand that was desperately grasping onto Izuku’s ass slide forward and rubbed his swollen clit making Izuku scream into the hand covering his mouth, his body jolting when Katsuki tickled the bundle of nerves under his clit with a thick finger.
Eyes crossing, Izuku’s body clenched hard around him, sucking him in every time he tried to pull out and Katsuki swore he would almost break his jaw with how hard he was clenching it, his hips pounding into the freckled slicked cunt and his calves were burning and sweat was steadily dripping down his back but it was all worth it.
It was so worth it.
Gritting his teeth, Katsuki fucked him harder making the smaller boy under him jerk back and forth on his cock, his tits swaying with each thrust and Katsuki’s fingers were dripping from the amount of slick coming from his cunt and Izuku was so damn tight, clenching down hard every time he pulled out and Katsuki flicked his clit faster, pinching it painfully between his fingers and using his thumb to swirl the bundle of nerves.
That seemed to do it because within seconds Izuku was cumming, his cunt clenching onto him so tight as his body jolted and twitched through his orgasm and Katsuki cursed under his breath feeling his eyes cross when the rapid clenching build up his knot and he fucked Izuku faster, his head jerking back when he felt the knot starting to form on his cock and he urgently moved his hand from Izuku’s mouth to grasp the bottom of his cock, squeezing the forming knot and groaning loudly when he felt Izuku’s cunt rock into his hand.
“M-M-more! I need more, Kacchan!” Izuku whined turning to look at him over his shoulder, his eyes were pulsing and glowing green, fuck he looked so ravishing being so sweaty with his wet curls pressed against his forehead and his lips red and swollen.
The blonde gritted his teeth already making up his mind to make Izuku come once more and his thumb went back to Izuku’s clit, heavily petting it without it being painful.
Izuku’s head dropped between his arms and his body trembled to hold himself up and Katsuki's jaw tingled at the sight of Izuku’s deliciously sweaty nape with a few curls sticking to the back of his neck. Katsuki mouth dropped voluntarily at the thin neck and his mouth started to salivate from the sight, he could feel his canine start to elongate, dripping venom and landing on the Izuku’s naked back, thick and yellow.
It was so easy to bite him right now, the dumb fucking omega was busy getting his cunt pounded in to even notice the Katsuki’s canines ready to sink down.
“Auh-auh-auh—! ”
Katsuki could claim him right here, knot him and get him knocked up so he could stay with him forever and ever.
“Mmh! Yes! Oh–ah! Mmng! Faster, faster!”
It’ll be easy, just one bite, Izuku was already cock drunk so he wouldn’t even care and actually his omega would be happy to be finally mated to a strong Alpha like Katsuki.
“So close! I’m so close! Kacchan–aaah! ”
No he couldn’t, he wouldn’t lose Izuku’s trust like this, it was Izuku’s choice not his despite how desperately he wanted to mark his naked neck. Claim Izuku as he always wanted to since the moment he laid eyes on the big doe eyes and the curly head full of hair, his mouth going a mile a second talking about the latest All Might comic books. Katsuki fell hard and fast for the stupid nerd.
His stupid nerd.
Snarling, Katsuki squeezed his knot in his fist making sure it didn’t grow any bigger because that would create a horrible situation for him.
Just to tease Izuku, he leaned down and licked a tongeful of his sweaty skin, his fangs just gently scraping at the tender skin and Izuku’s body tensed up, his cunt clenching painfully around Katsuki's cock making him moan loudly at the feeling of his cock being trapped and sucked in by Izuku’s delicious heated cunt.
Izuku whined high in his throat and Katsuki let a low groan of his own, his tongue tingling when he tasted him, it was sweet and tangy from the sweat, the taste alone was enough to send Katsuki into overdrive and yanked Izuku’s arms back, gripping tightly onto each wrist so he could ram into his swollen cunt like a madman, his balls slapping Izuku’s clit with each thrust.
The repeated breathless moans and cries that escaped the omega under him fueled his body and he had forgotten about the knot slowly growing and with every rapid thrust and in the back of his mind there was a fear of Katsuki accidently knotting Izuku in this dirty alleyway.
“Yes–yes—ah–ah–ah!”
Katsuki couldn’t hold it anymore, Izuku was hot so fucking hot inside and out. His body glistened with sweat and Katsuki felt eyes roll back when Izuku would clench his velvet walls around him. Katsuki cursed low in his throat and his head lulling back as he fucked Izuku faster ignoring the cramp building up in his leg or the slight skin irritation around his hips and thighs.
Katsukis squeezed Izuku’s wrist tighter and he gritted his teeth as he came, his body jerking forward rapidly and frantically, emptying his load in Izuku’s cunt, the hot seed planting itself in Izuku’s cunt had him cumming a second later, Izuku’s body tensing up and he let out a loud drawn out moan, his cunt clenching and unclenching around his cock milking him dry.
He would need a morning after pill for sure with how much his cock unloaded itself inside Izuku. Speaking of the omega, Izuku’s body twitched with the aftershocks of his orgasm while Katsuki continued to thrust into him slowly to ride out his high, the wet squelching sounds of their cums mixing together filtered through the air between Katsuki’s groans and Izuku’s short rapid moans.
“Fuck,” Katsuki muttered feeling himself grow soft and he reluctantly pulled out slowly with a wet squelch, moaning at the size of Izuku’s gaping hole with his cum steadily dripping out of it and he was desperately trying to clench to keep it in but it was no use, it was a river of cum coming from the gaping hole.
“What a mess,” Katsuki mused and the Izuku only moaned in response, his legs finally giving out but Katsuki was quick to catch him, holding him close with an arm wrapping around his waist while Izuku’s body flopped forward uselessly like a rag dog and for some reason it boosted Katsuki’s dumb Alpha ego knowing how good he was able to fuck his omega useless.
“Give me a second,” Katsuki said, reaching back into his sagging pants and pulling out his phone, quickly dialing up Kirishima.
“Yo! Dude where’ve you been! The party started like an hour ago!”
“Come pick me up, shitty hair” Katsuki demanding and there was a pause before Kirishima quickly asked why and started to fake tear up, “Can't believe your asking for help man, finally growing up I see ,”
“Shut the fuck up! I’ll send you my location and get here as fast as you can or I’ll fucking kill you!” Katsuki snarled while hanging up, sending his pinged location to the fake redhead and turned his attention back to Izuku. Glancing around, he managed to find a concrete stoop that led to a metal doorway of an establishment, he carefully walked over and gently deposited Izuku on the last steps leaning his body back against the metal doorway.
“I know it’s not ideal but stay with me,” Katsuki muttered, getting back up and paused looking down at his dripping soft cock, he quickly shoved himself back in his pants and zipped himself back up. Katsuki held back a grimace at the uncomfortable feeling of his boxers getting sticky but he would have to make do until they got back to his apartment.
Katsuki walked back over and retrieved the rest of Izuku’s clothing which was literally only a baby blue thong and his skimpy white skirt, he also grabbed his jacket before jogging back over to Izuku who had finally started to gain some sort of consciousness.
“Kacchan?” Izuku rasped weakly rolling is head to the side, the blonde quickly leaned down and his cock pathetically twitched in his pants at the site of Izuku’s spread legs exposing his messed up cunt, “Alright, c’mon put these back on,” Katsuki ordered, there was nothing else to clean Izuku up with so he had to hope for the best that they got to Katsuki’s apartment quickly.
He shimmied back on the thong holding, he almost wanted to tease Izuku but shoving it between his messy lips and grinding the fabric against his clit but he was not about to do round two in a dirty alleyway, Izuku deserved better than this.
“Now the skirt,” Katsuki muttered pushing the skirt up, there was some resistants from his thighs but Katsuki managed to get it up and over his hips and tugged down the top over his breast, adjusting it so nothing looked a mess which was a lie, he looked like he had been fucked raw in a back alleyway. Which wasn’t a lie.
“Here put this one,” Katsuki said, helping Izuku wear his coat before he slumped back against the door, eyeing him warily and while Katsuki rubbed his cheek making sure to avoid Izuku’s suspicious gaze.
“You didn’t bite me?” Izuku questioned almost curiously and Katsuki snorted, rubbing the back of his neck still squatting in front of him, “I’m not an asshole,” Katsuki muttered, almost offended that Izuku thought so little of him.
“You also didn’t knot me either.”
“The fuck?! Did you wanna hang on my knot for almost twenty minutes extra?” Katsuki snapped, there was a pause between them and Katsuki was busy cursing his foul mouth for ruining the mood but he hadn’t noticed Izuku lean forward until those crooked fingers cupped his cheeks, tilting his head towards him and gently press a soft kiss near the corner of his mouth.
“Thank you,” Izuku whispered sweetly to him, Katsuki’s alpha gushed and whine happily, he too flushed deeply and he ducked his head down shyly, “Tch, s’nothing,” he muttered, forcing his lips to stay in a scowl but it didn’t look like he did a good job with how Izuku was smiling at him, petting his cheeks soothingly.
“Kacchan?”
“What?”
“My heat, it’s coming in two weeks—will you spend it with me?” Izuku asked to brush back the hair from Katsuki’s forehead, the blonde resisted the urge to tap his foot repeatedly with excitement and instead he shrugged awkwardly, “I–I guess,” he said with an accidental stutter making Izuku laugh at him.
“Shut up! Fuck you, spent it all on your own now and with your damn toys!” Katsuki shouted, yanking his face out of Izuku’s hand, who the hell does the nerd think he is for laughing at him like that.
“Maybe…maybe I would let you knot me during my heat,” Izuku offered ignoring Katsuki’s threat and he inched closer, gently scratching behind his ear and Katsuki pretended like he wasn’t preening into like a damn mutt, “Fuck–okay, yeah let’s do it. My place, get all your shit and I’m gonna knot the fuck out of you,” Katsuki hissed feeling his cock tent back up in his pants and he knew Izuku didn’t miss the reaction.
Katsuki’s eyes widened and his alpha started howling when Izuku leaned in, pressing his breast against Katsuki’s arm and brushing his lips against his ear, “I might also let you claim me, Alpha ,” Izuku whispered breathlessly and then pressed an open mouth kiss to his ear with breathless moan.
“Holy fucking—”
Katsuki's phone went off and he cursed his luck, he carelessly pulled out his phone from his pocket and answered it, ignoring Izuku peppering open mouth kisses all over his cheek moaning ever so softly.
“W-what!” Katsuki snapped, he heard Kirishima laugh and tell him that he was here, Katsuki quickly hung up at the same time Izuku pulled away from him with a gentle smile, gritting his teeth Katsuki stood up and yanked Izuku up along with him.
“Come back to my apartment,” Katsuki asked or more like demanded but with the flush on his face but Katsuki could care less, “Oh,” Izuku mumbled, shifting shyly the toes of his boots clicking against each other.
“Ditch your friends and come back to my place, I-I’ll treat you right and leading up to those two week, I’ll court you and I’ll keep courting you even after your heat,” Katsuki stated and Izuku flushed harder, his mouth dropping in a pretty ‘o’
“You’ll court me?”
“I will–am! I am going to court you, buy you nesting shit and a stupid collar and I’ll—I’ll do whatever it takes to be a good Alpha and you can’t say no!”
Izuku laughed, throwing his head back and covering his mouth, “Kacchan!” he gasped, eyes tearing up and they twinkled up at him, “Kacchan, how could I ever say no to you,” he breathed, pressing closer and wrapping his arms tightly around Katsuki’s waist.
“I’m going to court you”
“Mhm,”
“You’ll spend your heat at my place,”
“Okay,”
“And I’m going to be your Alpha,”
“Yes, Kacchan,”
“Even if your mom says no and your shitty step-dad tries to kill me,”
Izuku grinned and he tilted his head slightly to the left, “I’ll ask Kacchan to run away with me then,” he whispered, making Katsuki’s lips twitch into a wobbly shy smile and Izuku giggled at his reaction, “Shitty Deku,” he muttered, “No take backs,” he added.
“Never, Kacchan will always be mine and I’ll be his right?”
“Damn right.”
“Sooo? Can we go back to your place, I really need to shower,” Izuku said showing his legs to see Katsuki’s cum was dripping down his thigh and staining his knee high socks and Katsuki wasted no time in scooping him up and running towards the nissan cube waiting for them. He’s already wasted so many years before and this time, Izuku is his and he’s gonna make sure it stays that way.
