Like Brown Sugar and Petrichor

The undeniable buzz of excitement throughout the camp of the Crimson Dragon Party as they went about their morning routines was a hell of a thing to wake up to. Luckily for Katsuki Bakugo, he hadn't slept yet. Instead, he cracked his neck and cleared his throat. His entire body was stiff, and his eyes ached from staring at the same pieces of paper for hours on end immediately after walking through the camp, helping with last-minute preparations before the move. The lack of sleep and the day's early start combined into a sour mood. And all because his Second-in-Command, and the party's only Beta, Izuku Midoriya, wasn't around to do his damn job and finalize the details as he ought to have done. Katsuki knew he could have sought Izuku and dragged him back into his tent and forced him to do his damn job, but he would have wasted so much time searching for him and they couldn't delay their departure.

After verifying the tip of a raging dragon shifter terrorizing a village in the mountains, Katsuki had declared they would be heading out to see what the Party could do to help them.

Two weeks later, it was finally moving day.

What was sure to be a day of chaotic grace as their impressive band of adventurers began the arduous and exciting trek through the mountains, he would certainly need his wits about him, and his temper was well-known to cloud his judgement when he was provoked.

Rubbing his eyes, Katsuki grunted in displeasure and inhaled deeply. A lovely scent caught his attention, and he followed it to a mug sitting nearby. There, just within arm's reach, was his favorite enchanted mug with a neatly folded note on the lid and a bare plate with crumbs of what looked like there had once been a few pieces of cinnamon crumble cake.

"You're so dead, Zuku," Katsuki mused with a smirk. It was a phrase so common in the camp that no one batted an eye at it anymore, and had become warped into a phrase of endearment for whenever Izuku annoyed him. He vaguely remembered Izuku setting the dishes down before mumbling some lame-ass excuse before fleeing his tent. Katsuki hadn't been interested in eating anything at the time; he was too absorbed in his work, but now the need for something warm appealed to him.

Snatching the note between his ring and forefinger, he plucked the lid off the mug and inhaled the splendidly rich and bitter caffeine inside.

Katsuki idly licked the pad of his pointer finger and dabbed it onto the plate, collecting the remaining crumbs of cake before putting it into his mouth as he took his time unfolding the note.

Chief,

Have gone into town to get some last minute items. I don't know when I will be back. Go ahead with the move. If you must, leave me behind, and I WILL catch up.

-Zuku

Not even an apology for the inconvenience. Damn brat.

There was an unexpected but wholly pleasant additional taste to the usually simple baked goods. He wondered if their chef, Satou, had added a new spice to this batch in celebration of the big day or maybe he was trying to get rid of ingredients that wouldn't travel well.

"You're so dead, Zuku," he repeated, doing his best to refold the note. He should have just burned it; it was just another piece of paper that was going to be packed, but something in him carefully refolded it and added it to the messiness of his desk.

The mug was a recent gift from his Second-in-Command. Katsuki remembered snapping at him for taking so damn long perusing the town's shopping district and he stormed off back to the austere comforts of the camp. It was later that evening that he spotted the small wrapped box on his desk, Izuku's weak graphite shavings and fresh paper scent all over it. He opened it to find a mug that fits the palm of his hand perfectly, and according to the square note, the mug would remain cold to the touch on the outside while its contents would remain at the temperature it was when it was first poured until there was nothing left inside.

He finally picked up his mug and tentatively drank, eyes closing at the first blessed swallow. Traces of the new, intriguing scent were around the mug, and Katsuki resisted the urge to sniff it.

Now that he thought about it, the smell was on Izuku's note, too. Well, that just confirmed the Beta had been the one to prepare and eat his breakfast. Izuku has been eating a lot lately. He was like a bottomless pi,t and the sight of the delicious cake must have been too much temptation for Izuku to ignore. Katsuki had teased him about it once, poking at his side and calling him fat, and nearly had his fingers bitten off for his trouble.

Izuku had immediately apologized for the outburst and made himself scarce for the rest of the night.

He had been making himself scarce for the last fortnight. Sure, there were signs that he had been in camp, doing his job, so it wasn't as if Katsuki could be upset at Izuku's lax in completing duties, but that didn't stop Katsuki from feeling bad that Izuku hadn't spent more than a few moments in the same space as him and they had spoken even less.

It didn't help that many of their party members had come up to him asking him to make up with Izuku. But that only served to piss him off. Not only had he not been aware they were fighting, but according to the party, Katsuki was the one at fault!

But Katsuki had swallowed his indignation and cornered his Beta the next chance he got. He had done his best to apologize, but Izuku had brushed him off saying there was nothing to be sorry for. That confirmation had been satisfying at the time, but when nothing changed in Izuku's disappearing act the next day, Katsuki felt like he'd been lied to.

What's worse, he just missed his friend and confidant.

His shitty mood had him stomping his way over to the tent of the Party's Relief Omega only to stop in his tracks when he spotted Izuku exiting the tent himself. Izuku had looked as flushed and sex-drunk as so many people at the party had after spending time with Denki Kaminari. As a Beta, it was a part of Izuku's duties to care for the Omega during his heats as he was the only person in the party who wouldn't be affected by the sights and sounds and scents of an unattached Omega begging to be so thoroughly bred. The sight of Izuku around Denki's tent wasn't unusual, it was the timing of it not being during a heat that had piqued Katsuki's interest in what his Second-in-Command had been up to.

It wasn't the first time Katsuki wondered what his second would be like in bed, but only in the way Betas as a whole baffled him. How could they go through their lives and not experience the sweet ecstasy of an Omega's intoxicating scent drawing them in or the immense high of completing a rut with a whimpering and satisfied Omega?

Seeing Izuku emerge from the tent that night had him questioning his assumption, so he went to the only source willing to talk to him to figure out what the hell was happening to his Beta.

Denki had stirred from his relaxed position in his chaise lounge when Katsuki appeared.

He had tried not to envision Izuku sitting there as Denki serviced him, but he couldn't deny the weak graphite shavings scent that still lingered in the air. Izuku had gotten off here. He had gotten off here recently. It shouldn't have mattered; all of the Party members were allowed to make use of Denki as long as Denki was comfortable with it.

Turns out, Denki was comfortable with a lot of things. Except for telling Katsuki about his time with Izuku.

"You know the rules, I don't kiss and tell."

It was an unspoken rule not to acknowledge when and how the party was with Denki, but Katsuki wasn't having it. He was the one in charge. "You just admitted that there'd been kissing at all, otherwise there'd be nothing to tell."

"Damn, you got me," Denki rolled over onto his stomach and looked over at his shoulder at Katsuki. "What does our esteemed leader plan to do about it?"

Katsuki placed a hand over his eyes and sighed, trying to stave off a headache. "Put that away, that's not why I'm here."

Denki's answering giggle had his cock twitching with interest. Okay, well, maybe he could go for a little playtime, but after he got answers.

"If you really want to know, come back an hour after sunset." They had a mild stand-off, but Denki didn't back down. It made Katsuki want to shred all their clothes and fuck the information out of him, but the urge passed as soon as it came. Katsuki had excellent control of his urges. He could wait a few hours to scratch that itch.

"Fine, you better not be lying to me."

"Please, Chief, I know better than to displease an Alpha."

Izuku's preferred name for him coming out of Denki's mouth didn't sit well with Katsuki, but it wasn't his highest priority right then. "Tch."

When he had arrived at the appointed time, it was to the sight of Izuku underneath Denki on that same chaise lounge, looking disheveled with his shirt and vest unbuttoned and Denki's hands deep in his green curls. Katsuki had been able to just make out the purple head of Izuku's cock peeking out over the top of his pants as Denki rubbed his against the rough fabric.

The tent had been heavy with Denki's earthy and golden honey scent and Izuku's graphite shavings and fresh paper scent. It had Katsuki breathing in deeply. Katsuki couldn't recall Izuku's scent ever being so pervasive before. The combination was causing an instant reaction from him. His earlier urge to tear off all his clothes and fuck had returned full force. He hadn't known why. It was obvious what happened in Denki's tent, and yet, seeing Izuku there, enjoying himself in a way that he had never witnessed before,e had him rock hard and excited. He had been eager to be Denki's next customer but he also hadn't wanted this scene to end yet.

Denki noticed him first, his hands turned Izuku's head to the side away from the tent entrance, and began to kiss along Izuku's neck. Using the new angle to block Izuku's sight Denki gestured for Katsuki to join them.

It wasn't until Katsuki was behind Denki that Izuku became aware he was there.

"Chief-" he had squeaked, his eyes widening. He had tried to get from under Denki, but the strong Omega only held him close, whispering words of appeasement and reassurance.

"Please, Zu. I asked him to come. I want this, too. Just this once. If you really don't want to I'll let you go, but if you wanna try this…You can just focus on us, Okay? The chief is here for me. He won't do anything to you, will he?" The last part had been aimed at Katsuki.

"Yeah, Dragon's Honor," he had said. It was the highest promise he could make. With that vow, he had basically created a new law that Katsuki wouldn't touch Izuku unless he wanted him to. (He was so desperate to be around Izu that he was wishing laws into existence just to make it happen.)

If Izuku had said no, Katsuki would have left. He would have returned to his tent and fucked his fist raw. And as he chased his release, he would do so to the thought of the two of them together. And he would be fucking touching Izuku. He might have staked his honor on not touching Izuku in that tent, but he hadn't promised not to do so in his thoughts. Lust and longing had him really hoping Izuku would go through with this.

Something passed between Denki and Izuku that Katsuki was able to see but not understand.

"Yeah, okay," Izuku had mumbled, his eyes entirely focused on Denki.

"Yes?" Denki had asked.

"Yes," Izuku had said clearly with a nod.

"Oh, you are too good to me," Denki had squealed in happiness and pressed a kiss to Izuku's freckled cheek in gratitude before reclaiming his lips. Katsuki had nearly come when he first heard the way Izuku moaned while kissing Denki. It had been like he was purring.

"Do as you wish, Alpha," Denki had encouraged, pressing his ass against Katsuki's crotch. The movement had both Katsuki and Izuku moaning together. Katsuki had stared and stared, desperately wishing Izuku's eyes would land on him so he could better gauge what he was feeling, but they were screwed shut as he sloppily kissed.

That was how Katsuki and Izuku had ended up sharing Denki at the same time. Katsuki's fingers had been stiff afterward with how hard he had held onto Denki's waist as he fucked him from behind spurred on by the way Denki had made out and frotted against Izuku.

It hadn't been his first threesome, though it was the first time he'd been with someone who wasn't an Omega. He had been entranced watching his Beta being sexually gratified. And he doubted he would ever be able to fuck anyone else and there not be three people, not after the moment his and Izuku's eyes had met over Denki's shoulder just before Izuku turned his head to the side and gasped softly as he came. He was pretty sure the image of Izuku's red and blissed-out face would haunt his sexual exploits for the rest of his life.

Katsuki had learned how affectionate Izuku was while they took great care of Denki afterward. Denki had clung to Izuku while Katsuki prepared his post-coital bath.

"Thank you for this," Katsuki had overheard Denki saying. "It was good, right?"

"Hmmm, it wasn't terrible," Izuku had muttered.

"That's what I love about you, Mido. Your optimism," Denki had laughed and Katsuki had looked over in time to see Denki press a kiss to Izuku's temple.

The pleased expression on Izuku's face had Katsuki's turning down in the opposite. He had started to see the bigger picture of what had been happening these last two weeks. Well, he had wanted answers. He was the only one to blame if he didn't like them.

Afterward, when Izuku had stumbled off to sleep it off in his tent, Katsuki had asked Denki how often it was that Izuku was visiting him. The answer had shocked him to his core. Every day. Every day for the past fortnight. Katsuki figured he now knew the answer. Izuku had a crush on Denki and he didn't want Katsuki to know about it.

It was pathetic.

It was…cute.

But mostly pathetic. It made his heart hurt at how cutely pathetic it was.

After that revelation he hadn't been as eager to have Izuku around him. If he was going to be a sulky fool in love then Katsuki was better not being around all of that.

He downed the rest of his coffee, ignoring the way it burned his throat. He reached for this crimson fur-lined cloak and pulled his arms through the straps, then shoved his feet into his boots and left his tent.

He had work to do.

It was easy for Katsuki to locate his Third-in-Command, all he had to do was pick out the mixed scent of mangoes and cinnamon from the myriad of scents encompassing in camp, and he would find him.

As he suspected, Eijirou Kirishima was at the center of things, helping their kitchen staff prepare and distribute the morning meal.

"How long 's he been gone?" He greeted Eijirou.

It's good that Eijirou didn't bother to confirm who he was asking after. There was only ever one he Katsuki ever meant. Instead, his Third-In-Command looked up into the sky using the position of the sun to judge the time.

"Two hours, give or take a few minutes."

So he left before sunrise. "Did he say when he'd be back?" Katsuki asked, helping himself to a serving of crumb cake. While it was still good, it wasn't as good as the crumbs had been. It must have been a special small batch.

Eijirou looked abashed at having to give an answer his leader wouldn't like. "No. But I am sure he'll be back in time for the camp-wide meeting. I mean, it's an important day, and it's his meeting," Eijirou said, trying his best to appease Katsuki. "Besides, if for some reason he doesn't make it back, I could always take the lead this time, you know, give a big motivational speech to pump everyone up. I've got this covered," Eijirou promised, flexing his arm as if that proved anything.

If the suggestion had come from anyone else, Katsuki would immediately suspect them of attempting to undermine Izuku's place in the party, but with Eijirou, Katsuki knew he was only giving a suggestion that would benefit all of them and not a ploy to socially advance. It was why he knew he could rely on him to pick up whatever slack he or Izuku let slip through their grasp.

"Do that," Katsuki snapped and spun around to go back into his tent. "I want to know the second that dead fool returns."

Eijirou saluted him and grinned broadly. "Understood!"

Katsuki nodded and grunted greetings to party members who braved addressing him as he stalked back into his tent.

"He's fucking dead," Katsuki grumbled for the four or fifth time that hour. The sun was nearly set and the camp moved on. He had lost sight and sound of them hours ago and Izuku still hadn't returned. Katsuki had to put Eijirou and his mango scented partner, Mina, in charge of the departure with strict instructions to not go looking for them. Katsuki had made the joke that he didn't want any witnesses around when Izuku finally appeared. But it was becoming less and less of a joke when he came across an unsealed letter during his tent packing. It was unsigned, but he didn't need one to know that Izuku had written it.

Katsuki couldn't remember ever feeling as pissed off as he was after reading Izuku's unsigned letter. Katsuki had spent his time waiting for Izuku to return meticulously planning out what he was going to do to Izuku, a chuckle issuing out of him whenever a particular detail amused him.

He was sitting atop his pack, wrapped in his cloak with his right cheek buried comfortably on the plush fur collar as he idly twisted the malachite plug in his left earlobe. It was a habit he'd developed by watching Izuku twist his carnelian ones whenever he was lost in concentration; while reading his correspondences or studying a map. He had made fun of Izuku for the habit, but now it had a strange calming effect on him and he could use all the soothing help he could get. He was absolutely livid with his Beta. He was debating on starting an evening fire when the inhalation of surprise had him jumping off his pack and on the alert.

"Hah! I'm surprised you showed up at all."

The shock of seeing Katsuki was evident on Izuku's face as returned to the emptied campsite.

"Chief, what are you doing here? I thought you left with the others."

"You would've loved that, huh? Woulda made it easier for ya ta abandon the party. Fucking coward."

"What?"

"That was your plan wasn't it? Set everything up so I could go on without you."

"No, I could never," Izuku protested, but Katsuki was too upset to listen.

"I saw the gods' damned resignation papers! I knew what you were planning to do."

"No, Chief, I promise it's not what you think."

"Oh? You weren't on some pretend errand so you wouldn't be here when we had to leave?"

Izuku froze when Katsuki impatiently stalked over to him.

"W-wait, stay back."

"Don't tell me what to fucking do," Katsuki growled until he slammed into an invisible wall of putrid smells and immediately covered the lower half of his face with his hand before the scent could invaded his nose further. "What the fuck is that?"

"Citronella and some other herbs," Izuku explained, shifting the straps of his own heavy travel pack on his shoulders.

"Why the fuck would you-"

"For the bugs," Izuku said weakly. He sounded near tears. "Chief, I promise if you give me a chance, I'll explain everything."

"Nuh-uh. You fucking reek. I'm not gonna listen to anything you say with you smellin' like that," he said, growing more annoyed. It was messing with his senses the longer they stood near each other. "Go to the river and wash it off," he ordered with a wave of his arm.

Izuku huffed but turned on his heels and headed toward the sound of rushing water.

Katsuki sat back on his pack, pleased that Izuku had listened to him. The disgusting scents must have been fucking with his head because he didn't think twice as Izuku walked off towards the river, when usually, he would put up much more of a fight before ultimately obeying him.

It was some time later when Izuku hadn't returned that Katsuki grew annoyed enough to go down to the river.

"What mess have you gotten your dumbass self into now?" Katsuki asked but his advance was once halted at a potent scent, only this time instead of being repulsed by it, he was drawn to how strong and incredibly delectable it was. It was rich and spicy, like burning wood and smoky leather. It reminded him of the nights spent around a bonfire, laughing with Izuku and mornings after when they shared coffee and cake.

Like the crumbs he'd sampled that morning.

Like Izuku.

"Hah?" he said as his mouth began to fill with saliva. He gathered it all and spat it out. He was reacting as if he were a shitty Alpha coming across an Omega in heat. What the hell was happening to him? "You're dead, Zuku! Where are you?"

Izuku's answering moan had a shiver go up his spine and goosebumps breaking out over his skin. It wasn't the resigned moan he usually made when Katsuki said the familiar phrase. No, it sounded more like one of pleasure.

He slowly approached the break in the treeline as the beguiling scent lured him closer to the riverbank.

The first thing he saw was Izuku's massive traveling pack on its side, the top open and its contents spilled all over the ground.

"Izuku?" He managed a few steps when he spotted his special shade of green hair.

He followed the repeating moan to the base of a tall pine tree where he found Izuku on his left side, facing away from Katsuki. The foul scents from before were gone, replaced with that sweet scent that was making Katsuki swallow so much. The rhythmic squelching of fucking into one's fist was barely audible of the rush of the river, but Katsuki heard it all the same.

"Don't tell me you can smell - oh, holy fuck," Katsuki breathed as he moved beyond Izuku's pack to see the full extent of Izuku's prone form. His shirt was undone and his vest had been discarded. His trousers and under garments were cuffed around his ankles exposing his bare legs and groin. There underneath his tightened flushed, purpling balls was a glistening pink slit. Izuku was soaking wet, but just not from bathing in the river but from the sweat and slick he was producing. "Izuku."

Izuku turned his head towards the sound of his voice and Katsuki saw a pair of Katsuki's under garments stuffed into his mouth. That wasn't the only piece of his clothing. He recognized some of his laundry he thought had been lost nestled along with the circle of Izuku's belongings that lay scattered around him in some rushed makeshift nest.

Izuku was an Omega. A late bloomer. It was rare, but not unheard of.

How long had Izuku been showing Omega signs?

The mood swings, the increase in appetite, the heightened sex drive…

The heightened sex drive!

He remembered how just before Izuku had come when they were with Denki, he had turned his head to the side and screwed his eyes shut as if begging to be bitten. To be claimed.

Fuuuck.

Izuku had been becoming an Omega for weeks now. How had Katsuki missed all of the signs?

"Please, help me, Chief," Izuku whimpered, his undergarment lay crumpled next to Izuku, who turned his head back to bury his nose into the smelly garment as he continued to pump his fist over his hard dick.

Izuku was a fucking Omega going into his first heat.

And he was asking Katsuki to help him get through it. Did that mean he wanted Katsuki to breed him?

That was the Alpha asking, hoping, that was the case. Katsuki was better than to give into those base desires. Though even he could admit he was having trouble pushing his growing desire for this newly developed Omega. Something deep within him wanted to throw off the shackles of his reason and join the breedable Omega, drive his cock deep inside him until he was begging for his knot. It was what this pretty Omega deserved. Why was the Alpha hesitating? Clearly, the Omega deserved it. And more.

Katsuki shuddered as he came back to his senses. He was losing it. Too much of his blood had left his brain too quickly at Izuku's scent. He was on edge. His cock was hard and aching, his balls heavy and, dammit, he was drooling. Seeing Izuku in such a state was driving him into an early rut. He had never felt this intensely during a rut before. He felt like he was shapeshifting into a mindless beast and all because of Little Izuku.

"Right," Katsuki said, crouching down and searching through Izuku's pack. "Do you have any suppressants?"

Izuku groaned. "Too–too late."

Of course it was too late to take them because the universe just loved to fuck with him.

So he did the next best thing and pulled off his cape. He thought he could give Izuku a better place than a bed of pine needles. His plan was to spread it on the ground next to Izuku and back away before the Alpha in him dug its horny claws into him. Izuku kicked off his trousers and underwear and rolled over onto it before it fully landed, immediately drawn to its scent.

His scent.

Fuck.

A hand whipped out and clamped around his wrist like a vise.

"Mmmmm." Izuku hummed pleasantly, pressing Katsuki's palm to his 's mind was going. His pupils were blown wide. He looked possessed by some sex demon and Katsuki was hanging on by a thread. Wait, if that was true then…

"Let go."

Izuku whined but released him only to burrow into his cloak as he cowered at the strength of Katsuki's Command.

"Thank you. Good Omega."

Izuku looked up at him and gave him a dazzling smile.

God, if any other Alpha got to see this…Katsuki would rip them apart with his bare hands.

He needed to look away. He needed to move away. He finally understood why it was that Izuku had made himself smell so terrible. He smelled better than anything Katsuki remembered anything smelling. The image of his morning coffee and his pre-eaten breakfast and Izuku's note had held traces of this, of his true scent. It was no wonder Katsuki had been attracted to it.

It figured that his biggest reaction ever to an Omega would be because of Izuku. He looked…incredible.

Their eyes met and Izuku's legs parted in invitation.

This was dangerous. Being this close had him wanting to get in between those powerful thighs and lick at the center of him.

Just a taste, he thought deliriously, taking a step closer to Izuku. Surely he could manage just a small taste.

Izuku's scent grew potent and more slick gushed out and ran down soaking into his cloak. Katsuki wondered if it would be enough to always smell like Izuku now, even after being through the wash.

He hissed through his teeth, trying to say "You're dead, Zuku," but he was losing his ability to speak so it came out as "Yo-Ugh-De-ku."

Gods, he was so hard and Izuku looked so ready for him.

Katsuki felt like an absolute bastard. Izuku was asking for his help because he trusted him to remain in control and here he was thinking about shoving his tongue deep inside him.

He was Katsuki Bakugou, renowned leader of the Crimson Dragon Party and one of the strongest Alphas ever known. He could help his Second-in-Command go through his heat-

"I need you. Please. Alpha."

Fuuuuuuuuck.

It was the first time Izuku had ever called him that, in that way. It was like a spell abolishing the law to not touch Izuku until he asked for it. Hearing Izuku call him Alpha had Katsuki on his knees crawling the last few paces to Izuku's beautiful form.

His right hand touched Izuku's left leg, gripping the knee. They both shivered at the rightness of it. Katsuki wanted to bite and lick and suck…to devour him.

That's what Katsuki wanted. What did Izuku want? He remembered how Denki had jerked him off. No penetrative sex. He could do that. Izuku was gifting him his first time and Katsuki would do everything he could to make it good for him. It was one thing that he and his Alpha wholeheartedly agree on.

The rite of finally being able to touch this Omega had him regain some of the reason he had lost as his early rut started overwriting his mind. He tried to speak.

"Can I taste you?" Was all he was able to manage before Izuku whined and lifted a leg in the air giving Katsuki permission to bite and lick and suck.

Katsuki grasped Izuku by the ankle and nuzzled his nose into the offered leg and inhaled deeply. His mouth watered again and he licked along the length of his calf.

He experimented with the force of the bites. Starting off with little nibbles, nothing more than his lips and the barest touch of teeth. Katsuki watched Izuku watch him. Katsuki recorded every expression, every exhalation, every flex of muscle that came over his freckled face. He wanted to know the very moment he found Izuku's Goldilocks zone where everything he was feeling was just right. He opened his mouth wider and teeth came into play, scraping the back of Izuku's knee. His tongue lolled out and licked at the sweat forming at the joint.

Izuku was shaking and panting heavily, the overstimulation egging Katsuki to take his time. "Chief," he puffed, taking huge gulps of air. "Harder."

"Mmm," he agreed and firmly bit down on the expanse of the squishy flesh of Izuku's thigh. Izuku's entire body spasmed when Katsuki's teeth broke the skin. He lost his grip on Izuku's ankle and nearly had his neck snapped in half as Izuku's thighs clamped down around the sides of his head.

Had Izuku just? A tight squeeze of his thighs and the fresh outpouring of Izuku's sweet slick confirmed it. Yes, Izuku had just orgasmed from being bitten. What an incredible Omega Izuku was turning out to be. His eyes closed on their own as aftershocks of Izuku's orgasm shook through him. Katsuki felt like a god, making Izuku come so quickly.

And he'd barely touched him at all.

Katsuki left a plethora of bruising kisses on whatever patches of skin his limited range of motion could reach. Light amounts of slick reached his tongue and he could have come right then at the taste. Izuku was delicious. He wanted more.

"Open," he Commanded. Izuku's legs parted instantly, releasing Katsuki from his succulent prison. He tore himself away from Izuku's legs and sat back on his haunches, collecting his breath.

"So-sorry," Izuku gasped in embarrassment.

"Don't be. That was magnificent."

Izuku blushed and turned his head to the side, his delight in Katsuki's praise evident. "I wanna touch you, too, Chief."

Katsuki's cock throbbed at the frantic need of Izuku's breathless words. But he knew it was just the heat talking, not his heart. Still, he could play this game. "So greedy. Trust me, we'll get there. But first, I wanna finish tasting you. I haven't had nearly enough of you. Maybe that's something you can help me with."

At Izuku's blank look, Katsuki chuckled deeply in the back of his throat. He reached out and a hand landed on Izuku's inner thigh. They both moaned as his hand practically sank into the warm plushness of it. All the extra food cravings Izuku had been indulging in had been his body's way of preparing for this first heat, for Katsuki's touch. His body was the perfect amount of fluffy and muscular. Soft and strong. His Izuku.

Katsuki's other hand joined and Izuku shivered and moaned as Katsuki's fingers dug into his fleshy thighs and Katsuki hoped that anywhere they touched it was going to elicit this reaction. He flattened his palms on the backs of Izuku's legs and pushed, causing them to fold inward towards Izuku's chest.

"Present," he Commanded.

Izuku's hands instantly shot out and held the backs of his knees, completely exposing himself to Katsuki.

Katsuki made him stay that way. Partly to just enjoy the sight, partly because he wasn't sure where to start. The imprint of his bite on his thigh was tempting him to do it again, but it was finally seeing more of the dick that had been plaguing his mind ever since he first caught a glimpse of the plum tinted head back in Denki's tent that drew his eyes more. It lay flush against his stomach, twitching and drooling with pre-cum, and begging for attention. He wished he had an extra set of arms or another mouth so he could indulge in every part of Izuku at once.

"Katsuki."

His name had his gaze meeting Izuku's. "Yes?" he asked casually, as if they were in the middle of a camp-wide meeting.

"Does this-? Am I-? Do I-?" Izuku bit down on his lip and groaned as he struggled to put his thoughts into words.

"Say it."

"Do I please you?"

What a fucking dumb question. Katsuki's thoughts must have shown on his face because Izuku flinched and broke eye contact with him.

The shy uncertainty in Izuku's question made Katsuki want to bully him.

He lightly stroked the length of Izuku's cock with two fingertips, testing Izuku's resolve. His Second-in-Command whimpered and his hips bucked, but he maintained his position. "Don't ask questions you already know the fucking answer to," he advised and didn't wait for Izuku's response as he leaned forward. He opened his mouth and let his drool drip over Izuku's cock and balls before he licked the length of it and took Izuku's cock into his mouth. He sucked hard, his tongue twirling back and forth over the head.

Izuku's head snapped back and he moaned, filling Katsuki's mouth with more pre-cum.

He swallowed it and his saliva as he bobbed his head but there was so much of it that it ended up pouring out the sides of his mouth. He let it as he increased the pressure of his suction whenever the tip of his tongue reached the head.

His left hand lightly explored Izuku. Through the short hairs around his groin passed his balls down to his slippery, swollen lips. His fingers dipped between the folds, gently rubbing up and down over Izuku's pussy, gathering enough of the slick for his purpose.

While one hand worked over Izuku's pussy, his other began undoing the buttons of his pants. He didn't wait to undo them all, when he had enough give to pull them over his hips, he did so. Once his aching cock was free he used his slick covered fingers and started to fuck his fist.

This was his plan. Using Izuku's slick to get off in order to trick his Alpha's senses into ending his rut and Izuku's heat without resorting to penetrative sex. It had seemed fool-proof when he first thought of it, but now he knew that it wouldn't be enough. Not for him anyways. But if it worked for Izuku, he would find a way to make it work for him, too.

Izuku was vibrating with pleasure and keening as Katsuki teased him. Nonsense spilled from his lips as Katsuki drove him to the edge. Just a bit more, Katsuki thought. He released Izuku's cock, replacing his mouth with his hand as he pumped Izuku in time with his own rhythm.

His mouth didn't remain idle for long. He kissed and licked a similar path his hand had earlier down Izuku's balls to his pussy were he finally licked at the prize he'd been clamoring for ever since he first scented Izuku's heat.

His mouth clamped down on Izuku's clit, and sucked on it harder than he had Izuku's cockhead, and Izuku was coming again.

A few more erratic pumps of his fist had Katsuki following moments later, his mouth filling with Izuku's slick and orgasm as he groaned into his pussy while his cock spilled onto his cloak. He bowed in front of Izuku, and breathed, doing his best to regain his senses.

"Ch-Chief."

"Hm?" Katsuki sat up and looked at Izuku. His knuckles were white as he dug into his knees as he attempted to keep his form. Izuku was breathing hard and looked like an absolute mess.

"You're so fucking perfect." The thought had slipped out without him wanting it to. Seeing him undone like that had only accomplished in making Katsuki want him more.

"Release," Katsuki Commanded and Izuku's hands let go of his legs and they fell to the sides.

Izuku's cock was still hard in his hand and even after just coming hard Katsuki was too.

He shifted so he knelt flush against Izuku. He added his cock to Izuku's in his palm, his thumb and forefinger making a tight ring for them to thrust into.

His pant legs were coated in his cum and Izuku's slick within seconds when his free hand reached down in between them and began rubbing his clit again.

"Hn!" Izuku's hands latched onto his forearms as he jerked into his hand.

"This okay?" Katsuki asked, speeding up his pace.

"Yes, but-"

"But what?"

"Need this inside," he panted, his eyes closed as he jerked into Katsuki's hand. "Need you inside. Do it like you did that night," Izuku panted. It was the first time Izuku had touched upon that incredible time with Denki together.

And, Gods, did Katsuki want that too.

But.

"I can't fuck you like that. Not for your first fucking time. Are you fucking stupid?"

"Nuh-uh," his weak protest turned into another moan as Katsuki's thumb rubbed over his clit in maddening circles, just as Katsuki intended. Let him stew in his own juices, Katsuki thought.

"Yeah, you're stupid as fuck, huh?"

"Yes," Izuku agreed, but it was in that tone that suggested that he was agreeing with Katsuki now so he could get his way later. "I still want it."

"I'm sorry, what do you want? I don't know what it is. Use your words, you damn brat. Tell me you want me to put my huge cock into you and fuck you until you come and die."

"Chief-Katsuki, please-"

"Say it."

"I-I want you to put it in me and die."

Katsuki chuckled at his poor attempt. He'd never had so much fun teasing an Omega before. He could get addicted to this. "Mmm, not good enough, my Little Izuku."

"Katsuki, please. I want-" Izuku's hand clutched at the hips of Katsuku's pants, tugging desperately at the fur lining in silent pleas for him to remove them.

"I said to use your words. You want your reward?"

"Yes."

"Then you know what you hafta do." He fully expected Izuku to go all soft and whine and plead for him to change his mind and give in and Katsuki probably would have done it after hearing it. What he hadn't accounted for was the fact that his partner was Izuku Midoriya and that he didn't always play by the rules.

Izuku reached out and grabbed a handful of Katsuki's necklaces that denoted his rank and position in the party. Katsuki had no choice but to follow Izuku's tugging lest the necklaces break. He wildly thought that his necklaces that proved he was powerful and important were currently being used as a makeshift leash and collar as Izuku wrapped his hand around them, drawing Katsuki closer to him.

The moment Katsuki was within reach, Izuku pressed their foreheads together. "I want you to take that huge cock of yours and fuck me with it until you die," he growled and then forced their lips together in their first kiss.

And Katsuki didn't hate it. In fact, he kind of loved how Izuku was making him work to prove that he was the one that gave the orders.

It didn't help that Izuku was an excellent kisser. Katsuki opened his mouth to him and Izuku's opened to match him. He had let go of Katsuki's necklaces in favor of wrapping his arms around Katsuki's neck. Izuku was making that purring sound like crazy as their tongues danced.

Once Katsuki was able to form thoughts again, he quickly got to work undoing the rest of the buttons on his pants.

Izuku moaned into their kiss when he felt the heat of Katsuki pressing against him.

"It's time." Izuku kissed him again, pursing his lips.

Katsuki nodded in the space between them. "Lay down."

Izuku loosened his hold on Katsuki's necklaces, the slight shiver of pleasure at the scraping of them over his flushed skin had him sucking in his breath.

"So damn pretty," Katsuki muttered. He kissed Izuku back, hoping the contact would be enough to distract Izuku from examining the words too closely. He took himself in hand and ran his tip along the length of Izuku's pussy, teasing Izuku senseless. They moaned in sync with each other when Katsuki lowered himself inside of Izuku.

He was so tight. Despite the river of slick that enveloped them both, he had used more force than he had been expecting when he pushed in and Izuku cried out in pain.

Katsuki stilled. "Izu. Sorry. I'm so sorry. I was tryin' so hard for it not to hurt, but you're so fucking tight that I-" Katsuki paused as Izuku's palm came up and wiped sweat from under Katsuki's eye. No, that wasn't sweat, but a tear.

"It's okay. I'm fine. I chose this. Don't stop. I feel too good to care."

Katsuki sniffed and accepted Izuku's words. "Okay, I'm gonna move now."

"Please."

"Gods, you feel incredible," Katsuki amended, sliding all the way inside, and he was embarrassed to discover he was the one trembling when he entered Izuku. "Need a minute?" he asked, trying to cover his reaction to being inside of Izuku.

Izuku shook his head. "No, move, please," he said and wiggled his hips as if proving that what he said was true.

Izuku gasped as Katsuki did as instructed and began to move.

"Oh, wow," he said smartly into his ear. "Katsuki…"

"Feel good?" Katsuki asked, his slow and steady pace had Izuku shivering every time he pushed back in.

"Yeah, now do it like you promised."

Katsuki chuckled. He liked that Izuku knew what he wanted.

"Alright. Hold onto me, Zu," Katsuki said, hooking his arms underneath Izuku. Their chests were pressed together and his hands were braced on Izuku shoulders for the best purchase as he made a few shallow passes into him. Just before Izuku could inhale the air to comment, Katsuki's thrust accelerated to a punishing speed.

"There. You, fucking, happy?" he gritted out.

"Ye-Yes. Yes! YES!" Izuku's hold on him tightened as Katsuki fucked him fast and hard. Each of his powerful, hip crushing thrusts had Izuku screaming his name and secondary.

"Katsuki! KATSUKI! ALPHA! ALPHA! ALPHA!"

Hearing Izuku lose his mind like that…yeah he was addicted. He's building orgasm was nearing rapidly. It might be the quickest he'd come since he was a teenager first discovering how his body worked.

"Izu, I'm about ta," he said in warning.

"Me too. Me too. So close. Please, right there!"

"No, I think I'm gonna come first. I gotta pull out!"

"Don't care, don't care, don't care! Come inside! Come inside! Please! Please! Please!" Izuku chanted and locked his legs around his waist.

Hearing his Omega's demand drove his Alpha into overdrive and his thrusts became erratic.

"You want my knot, huh?"

"Yes!"

"You want my knot so fucking bad?"

"Take it!"

"Gimme, gimme, gimme!"

He was so close he could taste it and that's when he noticed that he was the one being tasted as a shock of pressure on his neck sent him over the edge bringing his knot with him as he thrust one last time before stilling as his orgasm rushed into Izuku.

Izuku was purring as he bit into Katsuki's neck, the walls of his pussy squeezing him for everything he had and then some.

He was coming. He was coming inside Izuku and had died and gone to heaven. And he was pissed about it. He felt incredible, but that wasn't how Izuku's first time was supposed to go.

"You fucking idiot!" He shouted. "Why are you letting me do this?"

Izuku shrank at his question. And Katsuki felt like he'd just kicked a puppy.

"Sorry," he apologized instantly and closed his eyes. "I just. I don't understand why you wanted this. Were you just caught up in the moment?"

"If I get pregnant you don't have to worry," Izuku stated seriously.

"Hah? What bullshit are you saying now?"

"I-if I get pregnant I can take sole responsibility. My mother was a single parent."

"Oh, I see," Katsuki growled. "So you were gonna let any Alpha knot you your first time?"

"What? No!"

"Then what the fuck are you talking about being a single fucking parent?"

"Well, I'd never assume-"

"Yeah, that's a good start. Stop assuming shit and talk to me."

"I would if you'd let me finish a fucking sentence!"

Katsuki blinked at the curse word and then smirked as Izuku realized what he'd said too.

Izuku shifted and they both moaned again as it tugged on Katsuki's knot. Katsuki shuddered as pleasure rippled through him and the fight left him. He lowered his head to Izuku's shoulder. "You should have done this with someone you loved."

"I thought I had."

Katsuki pulled back to look Izuku in the eyes. He was smiling softly. Happily.

"What did you say?"

His soft smile turned into a knowing grin. "You have excellent hearing, Chief, you heard every heartbeat I had while saying it." Izuku's hands ran over Katsuki's arm and down his back, petting him. "I love you."

"No, you love Denki."

Izuku's hands stilled on his sides as he laughed. "What?"

"You love Denki," Katsuki repeated.

"As a friend, sure. But I am not in love with him. Why could I be when…" Izuku sighed, embarrassed to say it again, "I'm crazy about you?"

"Then care to explain why the fuck you've been avoiding me and hanging out with him all this time? "

"I thought I was supposed to be the stupid one," Izuku teased, but relented as an impatient Katsuki growled. "I've been feeling out of sorts for a while and Denki was the only person to realize what was happening to me. I thought I had food poisoning or that I was dying, but he helped me see that I was developing my Omega traits. He volunteered to teach me about my body and what things I could expect. It led to some…exploration."

"Okay, that explains why you've been attached to blondie, but not why you've been avoiding me."

Izuku snorted and rolled his eyes. "Kiss me," he ordered.

"Why?" Katsuki asked, already lowering his head.

"So I can remember why I am putting up with you," Izuku mumbled against Katsuki's lips. His hands moved up to the sides of Katsuki's head. Katsuki let him hold him like that as they kissed again and again. His knot pulsed inside Izuku and he broke off the kiss to moan.

"This is why," Izuku started. "I've wanted to be close to you for years, but as an Omega, my mind kept going fuzzy whenever I came across your scent. It was the first time I had ever felt the pull of desire. It was overwhelming. It still is. That night in Denki's tent. I wanted it to be just us. I wanted you to, well, it doesn't matter," he said, tracing over the bite mark he'd made on Katsuki's shoulder. "Denki knew how I felt. That night of us together? I guess it was his way of showing me how it could be when I wasn't in heat. It was good, but it wasn't enough. It wasn't this. But at the time I didn't know if - how'd you feel about everything."

Katsuki smirked at the knowledge, but didn't feel the need to let Izuku know how much his scent affected him too. "Is that why you wrote that quittin' letter?"

"I wondered what you were talking about. I wrote that ages ago when- oh, gosh, it's so embarrassing." Izuku covered his face with his hands.

"Izuku- I won't laugh or make fun of you. Tell me."

He lowered his hands so he could see the seriousness in Katsuki's face. "There'd been a rumor running through the camp that you were going to get engaged soon. In a moment of despair, I got drunk and wrote a letter resigning from the party because I didn't think I could handle seeing someone who wasn't you walking around with your mark. I passed out after and never sent it, obviously. I haven't thought about it since. I didn't even remember it until you brought it up."

"You are such a loser."

"Chief! You promised?"

"Did I?" Katsuki swallowed Izuku's protest in a kiss.

"What was that for?"

"To remind me why I put up with you. Finish telling me about your brillant plan not to end up fucked and knotted by the greatest Alpha ever."

Izuku laughed at how much that plan had backfired. "Well, Denki sorta scared the soul outta me when he told me about how first heats go. Mine was going to happen soon and I didn't want to be so vulnerable around camp. It didn't help that I would be cutting it close to Moving Day. So I devised a plan to deal with my heat on my own."

Katsuki listened as Izuku explained how he didn't want anyone else to know about the change in his secondary gender just yet. He hoped the others would have left him behind. He was confident he knew how to track them so he would be able to catch up when his heat had ended. So he'd gotten up early and gone to the apothecary's shop in town to stock up on suppressants and other pungent scents to help throw off his growing Omega scent and repel any unattached Alphas he may come across on the journey. Katsuki knew that meant him too.

But Izuku had underestimated how strong his first heat was going to be. And then Katsuki had found him anyway. It didn't help that Katsuki had used his command on him. The combo of his scent and his voice drove Izuku into his first heat.

"And here we are," Izuku finished and nipped Katsuki's lips with a quick kiss. "I have to say, it was one thing to read it in a book or to witness it when I took care of Denki but it's entirely different when I'm going through it." he leaned in and sniffed Katsuki's neck. "Your scent is still making my head go fuzzy. Is this how Denki feels all the time?"

"You'll have to ask him." Katsuki could tell that Izuku was returning to his senses as he began to go on a rambling rant about how it felt to be an Omega.

"Oh, right."

"I didn't fuck all the braincells outta ya, did I?"

Izuku giggled. "I don't think so, but it's not fair that I am the only one feeling this way."

"Not a one left," Katsuki muttered.

"What?"

"A brain cell."

"I'm confused."

"You honestly think I have been unaffected by this whole thing?"

"Oh, um, yes?"

Katsuki turned his head away from Izuku. "Tch."

"You gonna tell me I am wrong?"

"Your scent changed," Katsuki admitted.

"It did?"

"Yeah, before it was like graphite and parchment. Sometimes ink, sometimes glue."

"You're describing mail."

Katsuki snorted. "It fits you to the letter."

Izuku huffed and rolled his eyes, but his smile told Katsuki he enjoyed the pun.

"What do I smell like now?"

"My cum."

"Katsuki!"

Katsuki laughed and kissed into Izuku's hair, inhaling his scent. "It's hard to describe."

"Please, try. I really want to know."

"Hm, it's like a bonfire and leather and cake all rolled into one."

Izuku's face scrunched up at the strange combination. "Huh, that sounds pleasant actually."

"Hm. Let's just say it's a good thing that I'm already inside you."

Izuku shivered and pulled Katsuki closer to him. He turned to Katsuki's side and breathed in deeply.

"Is there a reason you're smelling my armpit?"

"Your scent has changed too."

"What are you talking about? You couldn't even smell me before today."

"Not true! I've been able to smell you for two weeks now!" He said proudly. Katsuki wasn't sure if it was because he had corrected Katsuki or because of his ability to smell him for such a short amount of time. Knowing Izuku, it was probably both.

"Okay, so what was it before and what it is now?"

"Like the outside."

"Like the outside?" Katsuki asked with a smartass smirk. "What the hell does that mean?"

"I dunno, like air."

"Air? I smell like fucking air?"

"That is not what I meant!"

"I didn't think Betas had such a bad sense of smell."

"Leave me alone, this is harder than I thought," Izuku whined.

"Okay, forget about my outside-air smell, what do I smell like now?"

Izuku inhaled again and giggled like he was intoxicated. "Sweet. Like brown sugar and water. Like the cakes we eat on our walks after it rains. Oh, that probably doesn't make sense."

"'S fine," Katsuki assured him. He rested his head on Izuku's shoulder as a swell of affection for him made his chest hurt in a good way. "You're so fucking perfect. Do you understand that? It's like the universe was just waiting for some reason to give you to me." Katsuki intoned. He lapped at the pulse point where Izuku's neck and shoulder met and then he opened his mouth. And bit down.

Izuku hiccuped at Katsuki's bite. "Katsuki."

"Hm?" he grunted over his skin.

Izuku suddenly went shy and looked away.

Katsuki grunted again, harsher and sucked harder, the wordless Command had Izuku crying, his tears hot and unending.

"I love you so freakin' much!"

Katsuki unhooked himself from Izuku's neck and kissed him.

"Yes. As you should, because you're mine, you got that? You better love me with everything you are 'cause I'm doing the same."

That declaration made Izuku gasp and his pussy squeezed the last of his release from him. The resulting rush of slick was enough to help Katsuki's knot calm down enough to be removed.

"The next time that happens, none of that is leaving you, understood?"

Izuku giggled. "Yes, Alpha."

Five days and several mating attempts later, they started seeing signs of the party in the new campsite. When they reached the outskirts of the camp, Katsuki halted their progress to fuck Izuku against a tree. He doesn't finish inside of him this time because he didn't want to accidentally knot Izuku when they were so close to the campsite.

"Come here, I wanna give you something," he ordered, after they'd dressed.

"I think you've given me plenty these last few days."

"And you'll keep getting it. You're stuck with me, Brat. But that's not why I want you."

Curious Izuku stood in front of him obediently awaiting whatever Katsuki wanted with him.

He loved how they could still bicker like this. He had been worried that Izuku would have become some obedient doll after his powerful bite. He should have known better than to doubt Izuku's ability to balance him out instead of being overpowered by him.

"Take your left plug out," he instructed simply, reaching up to his left side to do the same. "If you want," he added.

Izuku's eyes widened as he caught on immediately to the reasons behind Katsuki's request. "Yes, I do want!"

Katsuki had to chuckle at Izuku's eagerness. "Don't rip your fucking ear out," he warned, even taking his out had him wincing slightly.

"Maybe we should wait until we're back in camp to wash these properly." Katsuki thought aloud after Izuku had put his carnelian plug in.

"We can always clean them later," Izuku reasoned, tilting his head to the side so Katsuki could install his malachite plug into his ear.

Seeing Izuku wearing his color was making that tree look awfully tempting again.

"I really like seeing you in my color," Izuku said, idly twisting his newly acquired plug.

"Yeah, how much do you like it?" Katsuki teased. Fuck it, he thought. The Party could wait as Izuku took his hand and led him back to the tree.
