Midoriya Izuku was a normal omega in his prime, studying anatomy to be a physical therapist at yuuei university. He had a part time job at the local cafe not a ten minute walk from his campus and a twenty minute walk from his dorms. He had lots of friends that seemed to magnetize towards him but only a few close friends he really cared about. His mother calls him frequently to check in on him and from the outside he looks like a completely normal 20 year old omega.

But if you look around him, no matter where he is, if you look carefully enough you'll see the blonde hair and eyes stained with blood that follow his movements. A constant hover that never directly has contact with the beautiful omega with the scent of honey and thunderstorms. But even if you can't see the blonde you would still be able to smell his pheromones. The constant stench of fresh spilt blood lined with burning campfire. The smell so volatile it deters most potential alphas from approaching the green haired boy. His scent was like an aphrodisiac to those not familiar with him, drawing the attention of every alpha he passes. 

The only time he is free from the pungent scent is inside the cafe during his shift or inside his home. The alpha seems to follow everywhere he goes but still respects boundaries. His constant hovering concerns the omega’s friends and causes them to voice their concerns often. Like right now, at their study session in the university library.

“Izuku, doesn't it bother you?” Ochako whispered. Midoriya lifted his head to look at her across the table.

“What?” he asked, brows furrowed like he wasn’t aware what she was talking about.

“The alpha that's stalking you!” she hissed. “His scent is near overwhelming.'' The disgust clear on her face didn't seem to bother her friend who hummed with a smile turning back to his notes.

“I like his scent. Besides if he was dangerous he would have done something months ago. I think he's just watching. Maybe trying to court me.” a small blush rose to his cheeks as he tightened his grip around his pencil. Ochako’s jaw dropped. Out of every discussion they had had regarding Midoriya's alpha shadow, this was the first he had ever brought up courtship.

“Courting you?” she just barely managed to control her volume, though the smack of her hand on the cluttered table still drew unwanted attention.

“He left me something.” he mumbled, fiddling anxiously with his pencil.

“Something?”

“Yeah” he paused, knowing she was going to freak out. “In my dorm.” he nearly whispered it but it might has well have been shouted for his poor best friend. Ochako smacked a hand over her mouth as she attempted to silence the angered scream that wanted to spill out.

“Izuku! Inside your dorm? Are you fucking crazy? Did you tell the hall monitor that a psycho alpha broke into your home?” Izuku looked so guilty, his lips pulled back in a grimace and eyes trained on the ceiling to avoid her eyes. 

“Oh no.” her voice was strangely level. “You didn't.. And you're not going to.” Ochako looked so horrified at his subpar reaction.

“It was a scarf covered in his calming pheromones and the most romantic letter I have ever seen.” he looked almost dreamy at the messy notebook. 

“But Izuku, in your dorm. That's dangerous.”

“It doesn't feel dangerous.” he mumbled looking to the side. He couldn’t face her because he knew his argument was stupid. She was completely right. This was stalking and breaking and entering was a crime but he could feel the devotion in the scent left on his new scarf, a beautiful deep red that reminded him of his suitor’s eyes. He sighed and his eyes lazily traced the room for the familiar blonde but after finding none he raised his nose to take a deep breath. Spilt blood lined with campfire invaded his senses and he couldn’t help the fond smile that now decorated his freckled cheeks. 

“You actually like him. You like that he’s courting you.” Ochako seemed to slowly be resigning herself to play bodyguard for the stubborn omega. As a beta herself, she had nowhere near the natural strength the alphas were born with but she could still hold her ground and had slammed several cocky alphas to the unforgiving blue mat that she practiced judo on. 

Midoriya's subtle blush raged anew with a fiery vengeance. He practically combusted and whined low in shame. Ochako sighed dramatically loud and stood up. Midoriya looked up slightly to see his friend’s head on a swivel. 

“What are you doing?” he asked quietly. She stopped, staring across the library for a moment.

“Just gonna go have a chat with your stalker.”

“Please don’t scare him off!”

“Chill. Just gonna set some ground rules. Like no breaking and entering!” she hissed back, no room for argument. She started for the alpha and once within 10 feet the smell of him was near unbearable. The mildly tolerable scent when the campfire was there was gone. Only fresh spilt blood and ash danced in the air with his angry pheromones.

“Relax. I'm just here to talk.” she gasped out, hand pushing her shirt collar to her nose in an attempt to stifle it. The ash receded and the campfire returned with the blood taking a back seat. She breathed a sigh of relief but honestly his scent disgusted her no matter what.

She sat down a table away as the entire area had been vacated besides the hooded figure lazily slouched in a chair with his combat boots crossed on the table. 

“Are you courting my friend?” it was a question but the answer was so glaringly obvious she wasn't sure why she didn't figure it out without Midoriya’s help.

The man just shrugged and Ochako couldn't help but scoff.

“That's fine, my friend can take care of himself and make his own decisions, I'm not here for any of that.” he tilted his head and his rubies made contact with her own chocolate spheres. His eyes swam with such volatile emotions to match his scent, she couldn't help the slight shudder of fear coursing through her beta body.

“I'm here because you broke into his dorm to give him a gift. Gifts are great and are part of courting, that's fine and everything but you can't break into an omega’s dorm!” she glared at him and his scent switched again towards annoyance, blood leaking through slowly. She stood quickly.

“If you break in again, I will tell the hall monitor and get you banned from the building.” she left with those parting words and was surprised the anger did not intensify. Instead he seemed to accept that. Making her way back to her anxious friend who was faintly releasing distress pheromones she couldn't help but see this as dangerous. This alpha was stalking her friend and he liked it. What was wrong with him.

******

Katsuki Bakugo was a prime alpha with perfect marks in everything he had ever tried, attending yuuei university more for fun than actual schooling. Studying business management for when he would take over his parent’s million dollar fashion line in a few years. His first day of his second year was boring and he vaguely considered dropping out before he passed through the center courtyard and caught wind of the most deliciously mouth watering scent he had ever smelt.

Every omega and beta he ever had the unfortunate chance of smelling had disgusted him until that moment. Honey coated his tongue and showered him with the feeling of standing in a rainstorm. Fresh and refined. Perfect.

He spent the next 45 minutes scouring the courtyard full of new first years that still had that annoying pep in their step, before he found the source. A beautiful healthy omega with shiny green curly hair, good signs of fertility, and round rosy cheeks sitting high with splatters of fine freckles across them and the bridge of his nose. Glowing green emeralds shining with the laughter that twinkled like bells around him. He was on the shorter side like most omegas with a thinner frame but had wide hips, a thick backside and long legs. He was gorgeous and perfect and his. Maybe not yet but he would be. He was surrounded by two betas, an omega and one alpha, probably his friends from the mutual looks of delight being shared.

One of the betas was a girl, short and thin with brown cropped hair and brown eyes. Plain and unappealing to him. The other was a boy with fair skin and half white half red hair that was giving his omega too flirtatious looks. He would need to tell him to back off.

The omega with them had long greenish hair and was the shortest of them all with big black eyes and thin lips. Not a threat.

Lastly the unfamiliar alpha. Tall, broad, muscular, everything screamed alpha with his booming voice and jerky movements. Short blue hair and soft thin eyes when directed at the beta girl. Not a threat. He felt his inner alpha relax slightly with the alpha’s affections diverted. Half and half would need to go or be diverted but he can work up to that. For now he would watch and wait for a time to begin courtship. 

*****

It wasn’t for another 2 weeks before Katsuki had allowed the omega to smell him for the first time. He was alone, sitting under a maple tree in the courtyard. At this time of day, most students had classes and very few were mulling about outdoors. He stood upwind to let his scent carry down to the unsuspecting omega before peeling off his scent block patches and pushing his calming pheromones into the air. It was only a few seconds before Midoriya paused in his scribbling and lifted his nose to scent the air. His shoulders relaxed and his eyes drifted shut in contentment. 

Katsuki let the smell of warm campfires on chilling winter days invade the air for a few minutes before mixing in his usual scent of split blood only lined with the previous campfire. He could see him stiffen and his eyes slowly opening and his chest rise and fall with several deep breaths. Katsuki wasn't sure if he liked it or not. The reason for his scent blockers was because not many could stand his scent. He was a naturally hot headed alpha, which was quite common but mixed with his scent, it was overbearing and the sheer amount of disgusted peers he had come across urged him to use blocker patches to avoid the annoying complaining. 

He slowly replaced the patch until his scent disappeared almost entirely and Midoriya frowned. His eyes peering back at his notebook with a look of almost disappointment maring his pretty face. He looked back up and started looking around and Katsuki realized he was looking for him. He wanted to know who the scent belonged to. But if it was because he wanted to get closer or avoid the source was unclear so he remained hidden in the shadow of the tall lecture hall. 

His alpha whined in frustration at his master's hesitation, telling him to claim, mate, bite, breed, love. While he agreed he knew he wouldn't risk spooking the gorgeous creature.

He knew he took a risk with the breaking and entering but he was tired of having to ward off other suitors with his scent. His instincts drove him to provide and prove his worth, so he tried. He left him a scarf with his eye color absolutely saturated with his most pleasant calming pheromones and a letter that he poured his longing, affection and desire into. He hoped it would please him. He wanted his future mate happy and to feel safe with him. So when his beta friend had approached him the next day in the library from his seat far away to give space, he was nervous and uncomfortable. His go-to emotion of rage entering and overtaking his scent and crashing like a tidal wave over the surrounding area. The tears that sprang to her eyes and her muffled request for him to calm down was satisfying. What he didn't like was her insinuation that he would ever do anything to put his mate in danger or try to make him uncomfortable.

But he heeded her words and decided that it would be best to refrain from entering without permission. He watched her retreat to her table where Midoriya was mumbling incoherently and was releasing a mild distress scent. His hackles rose urging him to comfort, protect, cherish, hide his mate but he fought them down, waiting until they spoke for a minute before the scent dispersed and his shoulders relaxed from their tense position. 

****

He wanted to have him. Wanted to hold him tight and breath him in from the source. He wanted to fall asleep next to him and wake up just to make him breakfast in their kitchen. He wanted to cuddle with him on their couch and watch movies or play games. He wanted to spoil him rotten and give him anything he desired in this world.

He finally worked up the nerve one cold winter’s day, almost 6 months after his first sighting and after two months of giving him gifts. He saw his omega standing alone at a bus stop across from the cafe he worked at in the cold. The first present he ever gave him wrapped tightly around his neck with his nose and mouth protected from the chill. It was what finally got him to suck down his nerves and approach him.

He was cautious and he had gotten within just a few feet before he lifted his head for a moment and his nose was freed from the scarf’s confinement. In one breath his eyes shot wide and he whirled around to come face to face with his secret admirer.

“Are you finally going to talk to me?” he asked quietly, his eyes pleading for him to do something, he wasn’t sure.

“Yes.” he grunted, very smooth. The brilliant smile that encompassed his cheeks melted his heart and he found himself unable to bite back his own small grin.

“I’ve been waiting for months now.” he toyed with the end of the red knitting. “You have something you wanna ask me?” he looked up to meet his eyes and took a step forward, the hope shining there was impossible to miss and Katsuki was weak to him.

“Will you let me court you properly?” it was so quiet and so out of character for him but the nerves twisting in his guts was making it difficult.

“Only if you tell me your name.” he smiled softly.

“Katsuki Bakugo” and Midoriya beamed at him, wrapping his arms around the blonde’s neck and pushing his face into the greenette’s neck. Katsuki was in heaven. His long arms wrapped tightly around his much smaller frame and pressed into him taking deep breaths of the intoxicating smell that was pumping out waves of happiness. His own scent having not a trace of blood or ash. Only the distant and rare smores leaking into his usual campfire heavy smell.

Katsuki felt his chest rumble with an instinctual crooning of his delight and Midoriya's answering purrs only sent him soaring higher.

*****

After that night they were practically inseparable. Katsuki was with him everywhere. Anytime he had been previously stalking him he was now found at the greenette’s side, his arm wrapped prosessively around his waist and glaring at any alpha that came close. He wore scent blockers again much to Midoriya's disappointment but made sure to thoroughly scent mark him at the beginning of everyday and anytime his boyfriend asked him to. He personally didn't enjoy the scent blockers either but he needed the approval of his friends unfortunately so he compromised. He was fine with dowsing his mate-to-be in his scent and blocking his own. He loved the way their pheromones wrapped together into the most pleasing burning rainforest scent.

It took a few weeks but eventually he earned the approval of all but the two toned beta. He was expecting that though. He had agonized the previous six months within himself not to tear the beta to shreds everytime he let a touch linger too long at his shoulder or waist. Everytime he showed the omega affection and when he actually confessed and asked to court him he actually carved deep gouges into the cement wall with his feral claws. He had managed to slap scent blockers on before his scent swarmed the area with murderous intent. The only reason he didn't rip him apart was because his little omega kindly refused his attempt to claim. They remained friends which led him to his current situation. 

The beta’s usually passive face was scrunched up in outward disdain as he starred as the arm hooked around the petite omega. The group was chatting animatedly about a new movie that had recently been released aside from the sulking beta and the smug alpha. He could survive with just one of his mate’s friends not liking him. 

His other friends that he had learned the names of were, Iida, Ochako and asui, and they didn't mind the blonde very much. He stayed out of their conversations for the most part and didn't keep their friend from them so he had gained approval quickly. Even Ochako who had been so bold as to threaten him when he crossed a line had warmed up to him. 

Katsuki was happy. He could wrap his arms around the boy and press his face to his neck whenever he wanted. Everything was perfect.

Until it wasn’t. His rut had snuck up on him and he only had a day before it would hit him full force. He hastily dialed his boyfriend as he paced through his dorm.

“Hello” his chipper voice rang happily.

“Hey, love. My rut came early, gotta prepare everything in a day so I won't be in school for the next week. You gonna be okay?” he asked cautiously.

“I’ll be fine, Kacchan.” The pet name rang through the receiver and warmed his heart, the embers of his desire stoked slightly with his omega's voice so close.

“Will you be okay without me?” His voice was small and timid.

“I'm definitely not going to have our first time be during my rut, darling. Ruts aren't sweet or slow or patient, I won't be in control of myself. I can survive a week, don't worry.” he soothed him. The thought of Izuku joining him in his rut was definitely tempting and very hard to resist but he wanted to talk care of him during their first time together so he shoved his instincts down and began pulling a plastic bin from his closet that had things to help him through it.

“Do you want some of my clothes?” his voice came through a bit louder this time and Katsuki shuddered with desire. Having clothing of his partner during his rut would be heaven scent and much more pleasing than anything he could ever get elsewhere.

“If you don't mind, it would be great.” he smiled. He was so lucky to have his little omega. His caretaker instincts were extremely high, always trying to take care of others before himself.

“Okay, I’ll prepare some tonight and drop them off in the morning okay?” 

“No. my rut will begin sometime during the night. If you want to bring me clothes you have to get them to me before tonight.” he was stern. No way was he going to let Izuku anywhere near him after his rut started.

“Alright I'll see you in a few hours then.” he hummed and they exchanged good byes.

Just around 8 o’clock that night a knock came on Katsuki’s door and he put down the steel cuff he would be attaching to his ankle soon. Treading carefully he looked through the peephole and was gifted with a flushed freckled face looking around anxiously. Katsuki opened the door and let out a breath of relief when he couldn't smell his scent. It would have probably pushed him over the edge right then. Midoriya smiled at him when the dark cedar wood revealed the familiar head of blonde and crimson eyes.

“Here, these are for you.” he held out a cardboard box and Katsuki took it from his hand, noticing the clear patches over his wrist glands as his neck was covered by his red scarf.

“Thank you, I appreciate it.” Midoriya fidgeted for a few seconds before taking a deep breath.

“I know this is kinda reckless but will you scent me one last time before you lock yourself up?” His eyes looked so pleadingly and Katsuki had a very difficult time rejecting that. His alpha screamed at him to please his mate but Katsuki had to fight passed that to protect him in the long run.

“Izuku, that's too dangerous.” he sighed, unhappy about the refusal. “But” he cut in seeing the pure disappointment on his face, he should never take him to vegas.

“Give me your scarf. I can scent that while you wait outside.” he compromised. Midoriya seemed content with that and his favorite smile was back in place. He quickly handed over the cloth, revealing his other two clear patches and stepped into the hall again. Katsuki nodded and gently closed the door, retreating back into his room before peeling a scent gland clean of the patch and wiping the scarf over the pouring scent over and over until he was satisfied that it would last. He slapped the plastic back over his neck and returned to his love that waited patiently behind too thick of a door.

Midoriya brightened as he brought the scarf back to its place around his neck, cooing happily into the soft material. Katsuki smiled fondly and dragged him in to plant a soft kiss to his mouth. Midoriya pressed into it as well before Katsuki broke away too soon for either of them and finally sent him on his way after making sure Midoriya knew to stay away from all alphas and ‘half and half bastard’. They shared one last kiss and the door was shut.

****

Katsuki would forever be grateful for how thoughtful his soon-to-be-mate was. He had dragged the delivered box back to his room where he had found it to be filled with large ziplock bags filled with clothing. He pulled out of the many nearly airless bags from the bag and peeled it open only to be hit with the scent of his boyfriend’s slick and arousal, sending him crashing into his first round of rut.

He smashed the damp shorts into his nose and mouth and sucked in air greedily. Falling to the floor and not even bothering with getting to the bed before his mind was hazy and his clothes were far too confining. He ripped his sweats off his body, releasing his pulsing erection into the open air. He hissed as he wrapped his hand around it, jerking roughly as he kept the smell of slick crushed into his face. The tangy smell with the sickly sweet taste washed over his senses and pulled a loud groan from his throat. He mindlessly reached for his bed and pulled a rut sex toy from it, shoving his aching length into the cocksleeve. He groaned and rolled onto his back, writhing in ecstasy as he rode out the pleasure his mate had given him. He called out Izuku’s name over and over into the empty room filled only with the sound of his own cries and the squelching of the poor imitation for a green haired partner. 

He adjusted the clothing slightly and pressed into a fresh section of slick. 

“Fuck!” his shout echoed as his knot pulsed and his cum shot into the tight toy. His chest heaved as he slowly came down from his high, pulling the crumpling cloth from his face and sitting back up shakily. He would have a few minutes before the next wave hit and he looked through the rest of the box finding five more identical bags as the first and two more that had sticky notes with hearts on them. He pulled one of the separate bags out and found it to be filled with different things. He saw a pillowcase and a different scarf, several beanies. The other one was just a blanket, easily the biggest in what looked like a vacuum seal bag. He pulled the smaller bag out and cracked it open. Suddenly he was surrounded by a calm rain storm lined with honey in what was clearly Midoriya’s calming pheromones. Yeah. he was so, so lucky.

****

Midoriya was miserable the entire week. He never realized the effect that Katsuki’s presence had on other alphas. When he had been watching from afar, his pheromones were so strong they deterred almost everyone away except his friends who were persistent and stubborn. When he had finally come forward and they became official he had begun wearing the scent blockers again but he was such an alpha male that no one dared try to challenge him.

Without Katsuki’s presence and his overpowering scent he had been rejecting alphas left and right. His frustration was at a all time high by day 6 when his boyfriend's rut ended and he returned to school. He first saw him in the courtyard after his first class of the day and at that same moment he had two different alphas approach him at the same time. He growled lowly at their advances.

“Kacchan!” he called and his boyfriend was at his side in only a few seconds. Before he could start threatening the sad excuse for competition Midoriya pounced on him. Dropping his bag to the ground he gripped his shoulders and jumped up, wrapping his legs firmly around his waist and his arms around his neck. Katsukis hands immediately went to his thighs to keep him supported and stumbled back a step from the sudden weight shift before standing straight again. Midoriya's lips attacked him with a passion he matched at every drag of lip and swipe of tongue. During their intense and very public display of affection Midoriya had successfully ripped off his scent blockers and was now rubbing their necks together harshly, pumping out waves of his mixed irritation and happiness. 

Katsuki got with the program real quick and started to emit possessive growls and pumped out pheromones shouting mine mine mine MINE! Midoriya finally settled back down after he could only smell the burning rainforest scent and the strong arms of his alpha wrapped around him. 

Midoriya began purring and Katsuki replied with soft crooning as he walked them through the campus. Midoriya didn't care where they went as long as he didn't let go but he soon felt them stop and lower before he was sat in his lap and he could hear the chatter of his friends but he still didn't come up, pressing his nose against his gland and purring happily. Katsuki’s hands ran through his hair gently and he felt himself drift slowly with Katsuki’s calm pheromones lulling him into safety and comfort.

****

“Can one of you explain to me why he was so distressed when I came on campus?” Katsuki gave a pointed look to the four students seated around the table. Ochako giggled at the cute picture they made before ignoring the pheromones running rampant around their table.

“He’s been having a lot of problems with alphas all week. You started stalking him about two weeks after the semester started so students weren't really settled into routines yet and we didn't have to fight off that many alphas. This was the first time you had been away from him this year.” she took a sip of her juice, the others happy to let her explain it.

“Alphas I guess took the chance to try and woo him away from you. I even offered him my bat to help ward off horny boys.” she giggled. “Izuku was very firm with everyone, but they were relentless. You tell off one, two more come back. I suppose he was just happy to have you back.” she motioned to the koala that the omega had become as soon as he had seen him.

Katsuki let out a sigh of relief? Contentment? Stress? Who knew. But at least he was back and he could resume his place as boyfriend guard.

****

Izuku sat on his bed staring intently at the little plastic ring in his hand. He then stared at the sheet of paper it came with listing all possible side effects and directions of use. He grimaced but this was something he just had to do. He sighed and popped open the first pockets and swallowed the small pill with a gulp of water. He placed the wheel gently into his side table and folded the paper back up to put away later. Picking up his personal calendar he clicked his pen and wrote start on today’s date.

He was now officially on birth control. After he had confided in his friends about wanting to sleep with Katsuki, Iida had lectured him profusly on safe sex and demanded he start birth control if he didnt want pups yet. While he was right he still didn't like having to take stupid pills everyday. How annoying.

He stood up with a stretch and waited for Katsuki to get there. He still had about twenty minutes so he decided to make a nest to pass the time. Pulling blankets from his closet and the pillows on the side of his bed he continued to shift things around until he was satisfied. His inner omega whined, it still needed something. Something of Katsuki’s. He walked to his dresser and picked up his favorite scarf, wrapping it around himself he whined when all he could smell was himself. He wanted Katsuki and like he had summoned him there, three quick knocks hit his door. 

He smiled and walked swiftly to his door and looked through the peephole out of habit. He froze, that was not his boyfriend. The man was tall with black hair and dark purple scars covering a large portion of his face and chest from what he could see. As quietly as he could, he locked the second lock on his door for extra support. The man looked dangerous but very bored. Midoriya wasn't risking it and sent a text for help to Katsuki. The three knocks came again a bit louder than before and he heard a loud irritated sigh. Midoriya clutched his phone to his chest in anxiety and was extremely grateful he hadn't taken off his scent blockers from his shift at the cafe yet. Not a minute later a fist pounded on his door, rattling the lock and Midoriya bit back his whimper.

“Hey!” he heard a familiar muffled yell and he slowly peered into the peep hole again. His heart sang seeing his boyfriend standing toe to toe with the newcomer.

“You need something?” he asked calmly.

“Nothing from you. It’s not your business.”

“You think you pounding on my boyfriend’s door is not my business ?” he growled. Midoriya watched his eyes widened before he took a step back and groaned loudly wiping a hand down his face.

“Look man, sorry. Didn't know he was taken. Honestly I'm just a go between, sent by my friend who's got the hots for him.” he sounded so done with everything.

“Well tell your friend to go look somewhere else cause he's not available.” he ripped off one of his scent blockers and a crash of fresh split blood and ash flooded the hallway. Such aggressive pheromones permeated through every door in the hallway and he could hear several doors open around them but not his. No, he wouldn't open it until Katsuki said it was okay. 

He knew that this floor had mostly omegas and the agressive waves that promised murder and pain must have sent quiet a few into a panic but Midoriya felt them as protection and safety.

Safe, safe, relax, alpha will protect, alpha will provide .

Midoriya watched the man go from relaxed to stiff as a board in less then a second and then fear was flooding just under the stench of blood.

“yeah, I’ll do that. Bye.” he quickly headed for the stairs on the other side instead of passing Katsuki to get to the elevator. It wasn’t until the intruder was out of sight that Katsuki relaxed and reigned in his scent. He switched to his calming campfire and the distress radiating from the other room diminished. Midoriya released the latch on the lock but waited for his say so.

“Wanna let me in, babe?” he chuckled and Midoriya flung the door open and pulled him inside slamming the door shut and replacing all three locks.

“He really scared you, huh?” he pulled Midoriya into his firm chest, running his fingers through his hair to calm him. Yes Midoriya was scared of the strange man but he was more happy to be able to snuggle into his alpha’s chest.

“Mmm.. come snuggle with me.” he pulled away and walked to the back, Katsuki following close behind. The greenette immediately snuggled into his nest and waited for his alpha to join him but saw him hesitating at the edge. 

To enter an omega’s nest was a huge sign of trust. The only ones allowed into an omega’s nest was their mate and mother. Nests were not something to be taken lightly.

“Are you sure?” he asked. He would not over step with his omega. He would wait years if that was what it took.

“It’s okay, Kacchan. I want you in my nest.” he gently pulled his wrist and the blonde kicked off his shoes before crawling in beside him. He pulled Midoriya into his chest and held him close, peeling off the scent blockers he was still wearing. Instantly happy pheromones surrounded him in misting rain and drizzles of honey in his tongue. He crooned against his nape and Midoriya’s answering purrs vibrated through his chest. Katsuki pulled the last blanket over them up to their chins and they fell into a peaceful calm letting burning rainforests soak into their bones.

Midoriya’s omega was preening and singing inside him. He thought that if Katsuki had asked to give his mark right then he would say yes.

*****

Katsuki had been courting his omega for 4 months now, doing his best to shower him in love and affection. He walked him home after every shift and stuck to his side whenever he roamed the campus. He should have been satisfied with his attention but he just couldn't settle down. every minute he spent wrapped in his scent urged his inner alpha to scratch at his cage and let him claim him.

Katsuki thought of the one thing besides mating that might placate his alpha. A collar. Collars were a visible item that omega could wear to show any potential alphas that they were being courted.

Typically they were given later in the courtship almost like an engagement ring for normal weddings. Such blatant intent to claim would soothe his alpha and repress his instinct to dominate and claim him. 

He had left campus during Midoriya's back to back lectures and had stopped inside three different collar stores with no such luck. The door chimed as he stepped inside the fourth store,  a beta stepping forward to greet him and he brushed her aside to look in the glass cases.

Collars of all lengths, girths and textures were displayed just like other stores but they all were just too gaudy. Covered in rhinestones or intricate patterns that made him want to scrunch his nose. He scanned through all the cases quickly and nearly gave up on the last case but something caught his eye.

It was a simple thin collar made of leather in a dark forest green. Thin red lines in the form of fire danced across the surface finished with a gold buckle. It was perfect.

"This one." He called over to the two whispering betas. The blonde with far too much cleavage showing strutted over pouring out sharp lavender and pomegranate. It was revolting and he wrinkled his nose in distaste.

"Is this for an omega or beta?" She asked, bending over to give a clear view of her dipping breasts.

"None of your business." he hissed and removed one of his blockers from his wrists letting fresh spilt blood pour into the room with his annoyance. The beta stood straight and stiffly walked to the register, collar in a simple brown bag and gave him his total. He let his scent permeate the small room for the rest of his time there and left the two betas to cower. 

Satisfied, he replaced his patch and exited back onto the street. He was immensely happy with his collar decision. His alpha was preening and not grating on his nerves for once. Checking the time, it was getting late.

When Katsuki arrived back on campus he lifted his nose to the air to scent his omega, his senses now able to hone in on his pheromones from a distance. He could barely smell him, meaning he was far away. He began his track across the large university, passing sleep deprived students holding coffee cups or energy drink cans. It  looked like a horde from the walking dead of mindless zombies. He guessed that was what finals did to people. 

Midoriya had been studying nonstop for the past 3 weeks in preparation and he was only allowed to cuddle against him while he studied. They hadn't really talked a lot during the stress so maybe that's why his alpha was throwing a fit. But today was his last finals before spring break and he was going to be able to lock him away and have him all to himself.

His omega's scent gradually became stronger until he could drink him in. His back was turned from him as he was chatting with Ochako as Katsuki crept up behind, wrapping his arms tightly around his abdomen nuzzling into his nape.

"Kacchan! You scared me!" he giggled and his joy spread honey around them.

"You're done for the day, right?" 

"Yeah, I'm all yours." he leaned back into his embrace and Katsuki sighed. This is what he wanted forever. No one would ever take his omega from him. 

"Good.'' Midoriya said his goodbyes and they started for the familiarity of Midoriya's dorm. 

*****

“I got you something.” Katsuki’s heart was in his throat, pounding so hard he could feel the pulse in his fingertips.

“Another courting gift?” his head tilt was adorable.

“Something like that.” he mumbled and handed over the inconspicuous bag with a shaking hand. He clenched his fists in his lap as he watched nimble fingers gently part away the brown paper. The only thing keeping him from bolting from the room was the heavy scent of burning rainforests that soaked into every corner of the dorm, concentrated in his place in his omega’s nest.

Midoriya gasped as he removed the stiff leather and clasped his hands over his mouth, tears falling from glassy eyes as he looked back at Katsuki. His alpha was full panicking. There were tears and he was sobbing but there was no distress, only vibrant honey and crisp rain showers broadcasting his joy. 

“Babe?” he asked, his voice strained as he moved his hands back and forth mid air trying to decide if he should comfort him or not.

“I’m so happy!” he finally choked out, picking the collar back up with shaky hands and thrusting it into his alpha’s chest. “Put it on me!”

Katsuki felt his shoulders sag heavily letting out a deep breath he didn't realize was stuck in his lungs. Understanding passed through him and he felt his campfire scent meet his boyfriend’s in response to his excitement. He gingerly took it and undid the clasp before slowly pulling it around the greenette’s thin neck and clasping it loosely. He pulled his hands away and smiled fondly, his alpha dormant with the croons rumbling in his chest in approval. 

Midoriya scrambled out of his nest and over to his dresser mirror. He stared at his reflection for a minute before bringing his hand up to trace over the material. His radiant smile pinched his flushed cheeks and his glassy eyes crinkled. He turned around and returned to his companion, wrapping his arms around his neck and straddling his waist to have as much contact as possible.

“It’s beautiful.” his voice soft and wobbly from his running tears.

“I’m glad you like it.” he wrapped his arms around his waist and buried his nose into his neck, swiping his tongue over his scent gland. The coating of fresh rain that hit his tongue like crisp sweet water made him salivate. He sucked lightly as Midoriya nosed at his alpha’s neck, purring loudly in satisfaction. His inner omega was crying with joy at his claim. It wasn’t a mating mark but it was the promise of one should he accept it.

They stayed wrapped up in each other for a long time, just enjoying the comfort that came from their partner. Letting all traces of stress ooze out of their systems. 

“Kacchan.” Midoriya whispered against his skin. “I want you there for my heat.” 

Katsuki went rigid. Spending a heat with his omega was one of the most arousing thoughts ever introduced to him and he felt his dick respond in kind, swelling with his arousal. He groaned deep but quietly, muffled in his shoulder.

“Babe, I don’t want our first time to be during a sex haze.” he started.

“Then take me now.” Midoriya pleaded, lips pressed to his ear. Katsuki groaned much louder, his arms tightening almost painfully around his omega’s ribcage before releasing him and pressing him to the bed.

Surrounded by their pheromones in the comfort of their nest, Katsuki couldn't refuse if he wanted to. He pressed their chests together as he pinned him down, Midoriya’s legs spreading naturally for his alpha to settle between.

“Izuku” he called between pressing kisses down his jaw. “Are you sure? I can wait if you're not ready.” he pulled back up to cradle his intended’s face, stroking his thumb over his cheek. Midoriya smiled at him, warmth blooming in his chest.

“I’m sure.” he nodded and closed his eyes as their lips came together. Softly moving against each other in a slow dance before Katsuki nibbled at his lips and pushed his seeking tongue through. Stroking his opponent’s and licking over his teeth. Midoriya moaned softly, fingers smoothing up his back to tangle into his short blonde spikes. Katsuki pressed a bit deeper, sliding his left hand down to grip the bottom of his shirt and pulled it up slowly, only breaking the kiss for a moment to remove it completely before latching back onto each other.

Katsuki’s hot fingers glided over his exposed skin, sending tremors through his frame. He gasped into his mouth and the alpha trailed his lips down his neck in short kisses before biting softly into the skin just above the collar. Midoriya arched on a moan. The sharp sting of fleeting pain from the bite sparking his nerves alight. 

Their breathing picked up as they explored each other. Soon they were both free of their coverings and they writhed against each other, hands never staying in one place for too long. desperate to feel every dip and crease they could map out with their touch. Midoriya’s small omega penis leaked with precum from every harsh grind against the alpha’s much larger cock. The spicy edge to their scents of arousal mixed with the scent of slick flowing from Midoriya’s vagina sent pulsing need, deep into Katsuki in an aching instinct to provide him pleasure. 

Katsuki claimed his lips in a deep open mouth kiss as his hand trailed up the inside of the smaller man’s thighs before lightly stroking his soaked heat. Midoriya gasped and moaned, digging his nails into his biceps. Katsuki was in heaven, arousal coursing through his veins with every breathy moan and soft cry he pulled from the greenette. 

He prodded a finger against him for a second before dipping it inside. He froze at the sheer tightness of it, a solid hymen greeting him. He pulled back from his neck that he had been sucking galaxies into.

“Izuku, are you a virgin?” he asked wide eyed. Midoriya was flushed a bright crimson from his hairline to his chest, eyes averted in embarrassment.

“I just never found anyone I wanted before you so, yeah.” he mumbled, digging his fingers absentmindedly into his boyfriend's tender flesh.

“Fuck, that's so hot.” he planted a seering kiss to his mouth for a few seconds. “You know it's going to hurt right? I have to break your hymen.” 

“I know. I trust you.” he smiled and dragged him back down to him. With this new knowledge in mind he proceeded in his ministrations. He carefully began moving his thick finger in and out in a steady shallow thrust to get him accustomed to the feeling before assaulting his mouth and gripping the back of his neck with his other hand. The kiss distracts the omega from the stretch on the second finger. Midoriya keened into the attention, a shiver racking his body. The aggressive attention pulling a coil tight in his gut that he had never felt before. He panted as he just enjoyed feeling everywhere his alpha touched. 

Felt the odd sensation of fingers dragging against his insides. The slight burn when he spread the fingers apart. The constant thrusting inside him pulls whimpers and whines from his throat.

Katsuki bit into the flesh of his shoulder roughly as he added a third finger. Not hard enough to break skin but enough to leave a mark. His omega arched his spine with a long slutty whine at the attention and his alpha responded with a deep growl. 

Midoriya was scratching his alpha’s back, his leg hiked up over his hip and moaning depravedly.

“Kacchan… so good.. Please.” he cried.

“Please what?” he growled into his chest. Snaking his tongue out to lap against a flushed nipple then swirling his tongue and sucking. He keened, arching up into his mouth.

“Please fuck me.” he cried out, voice shaking with lust. Katsuki pulled back to sit on his haunches, taking in the beautiful image of his omega. Flushed cheeks, chest heaving with every ragged breath, dripping cunt stuffed full of his pruning fingers. His thighs trembled under his palm. He curled his fingers up at the same moment he grasped his penis and Midoriya screamed out his name, a flood of slick left him and a small spurt of cum covered his stomach.

Katsuki pulled away from him for a moment, giving him time to come back down from his orgasm, peppering his shoulders with kisses and rubbing his hand up and down his waist.

“Kacchan.” he slurred out, reaching for his face and Katsuki didn't hesitate to connect them. Midoriya pushed his hips up against him, feeling his aching cock that hung heavy and neglected against his abdomen.

“I want your cock inside me.” he murmured and Katsuki groaned throatally. He felt the omega's thighs shift farther apart and he angled himself down grabbing his dick and aiming the tip against his hole. He pushed inside slowly, only an inch or so to make sure he was angled correctly. 

“Do you want me to go slow or just get it over with? Like ripping off a bandaid.” he nuzzled his cheek.

“Just get it over with.” he mumbled but Katsuki felt the already extremely tight ring around his dick clench dangerously. He was nervous and it was making him tense. Katsuki poured out his calming pheromones for his love and dragged him into another searing kiss to distract him. After a few seconds of intense lip lock, Midoriya loosened slightly and Katsuki took the opportunity to thrust to the hilt, tearing through the hymen in one swift movement and stilled, hips flush with his trembling omega.

Fat painful tears escaped his face, his eyes clenched and Katsuki pulled away to brush them with his fingers and palms. He cried and whimpered at the pain and his alpha crooned to help him calm down. He breathed heavily through the pain for a few minutes as Katsuki waited patiently for the omega to adjust. He was so incredibly tight around him it was a bit dizzying.

“You okay, love?” Katsuki hummed. Midoriya let out a shaky breath, relaxing slowly around the intrusion. While his physical body was in a lot of slowly fading searing pain, his inner omega was controlling his pheromones and drive. Slick poured from him as his omega whined for him to breed him.

Mate, breed, bite, mate mate mate, give alpha pups, make alpha happy.

The constant whines from his omega helped him relax and within a few minutes the pain faded to a dull ache and the stretch became pleasurable. 

“I’m okay.” he breathed. 

“You're doing so good. Taking me so well. Wish you could see how gorgeous you look full of my cock.” he grumbled against his neck, sucking on his scent gland. Midoriya keened at the praise, his own small dick coming back to hardness quickly.

“Move.” 

Katsuki gently rocked against him, not pulling out quite yet to allow him to grow accustomed to the feeling. A pulse of pleasure echoed inside him and pulled a harsh gasp from his lungs, tilting his head back to press against the pillows.

Katsuki growled into his bared neck, his instincts to bite were strong. He pulled out a few inches and gradually increased the strength of each slow thrust. Midoriya moaned high, his nails digging into his lover’s shoulders on a harsh thrust, his cock hitting his g-spot.

Katsuki worked up to a solid rhythm, pulling whines and moans and cries from his omega as he pleasured him. every cry of his name that rolled off his tongue pulsing pleasure through him. The tight gripping heat encasing his throbbing length pulling him closer and closer to his peak.

“Alpha!” he cried out, his opening contracting around him. “Knot me!” 

Katsuki let out a possessive growl that echoed in the small dorm, slamming into his omega harshly. The hot coil of need in his gut was approaching quickly with every shout and moan that escaped his kiss swollen lips.

“Omega.” he groaned and his pace began to falter. Reaching between them he wrapped his hand around his bouncing cock and began to pump with his thrusts. The loud cries that were ripped from his throat came louder in an almost scream of ecstasy. 

“Alpha! Please! Give me your knot! I need it!” he had tears streaming down his cheeks from the over stimulation.

“I’ll give it to you if that's what you want. You want me to fill you? Pump you full of my cum?” he growled, he was so close. He could feel his knot beginning to expand. Stretching him just a bit wider each thrust. He gripped his hips to hold him steady as he rammed into him over and over. His thrusts were jerky and sporadic this close to popping his knot but the screaming omega didn't seem to mind. The bed shook and slammed against the wall, no doubt another unlucky student was being subjected to this.

“Yes! Knot me, alpha! Breed me!” he shouted and came across his stomach again. His vagina clamping down and pulsing with his orgasm. Katsuki roared and slammed home, fingers digging into his hips to keep them flush as his knot expanded and locked them together. Hot pulses of cum filling his omega just like he wanted.

They panted harshly against each other. Midoriya practically vibrated in ecstasy, trying to get his body to move how he wanted to. Katsuki slid his palms up and down his thighs and waist to calm him, crooning to soothe his omega.

“Hey” he whispered, his voice was strained from their love making but he tried.

“Kacchan.” Katsuki smirked. He was so wrecked. Midoriya couldn’t even focus, on the brink of passing out. His eyes dazed in his post orgasmic high. Katsuki smiled fondly at him and moved his hair away from his eyes as he waited for him to come back to reality.

It took some time but eventually he was able to make eye contact and the exhausted smile that he gave the blonde would remain one of his favorite moments for the rest of his life. A smile so filled with love and happiness it was impossible to put it all into words. So they didn't try. Katsuki returned his smile, pulling him into his chest and shifting them into a more comfortable position as they waited for his knot to deflate.

“Are you happy? Did I hurt you?” Katsuki asked quietly, one hand stroking his fingers through his hair and running his nails along his scalp while the other rubbed softly against his lower back. Midoriya hummed and snuggled his face into his chest.

“Yes, I’m happy and no you didn't hurt me. I mean it hurt at first but then it went away and you made me feel so good, Kacchan, don't worry so much.” he kissed his collar bone. Katsuki idly thumbed his collar and kissed his crown.

“Good.” 

They talked while they waited. Midoriya told him about his finals and how happy he is that he won't ever have to deal with his loud and obnoxious English professor again. He talked about how his mother is dying to meet him and has demanded that he come home to visit for the holiday.

“I’d like to meet your mother, if you want me to.” 

“Really?”

“Of course, you're going to be my mate. I need to thank her for creating such a perfect omega.” Midoriya burst into a fit of giggles.

“I wonder how she’ll react when I show up wearing a collar. She’ll definitely cry.” Katsuki groaned in despair. He hated dealing with crying people, he was never the most tactful person. 

His knot eventually went down and they quickly cleaned up. Midoriya demanded that he stay the night and cuddle with him until morning. And how could Katsuki refuse such an offer?

“This probably should have been asked earlier but are you taking birth control?” Katsuki asked after they settled down.

“I started two months ago so I'm covered don’t worry.” he paused for a few minutes, drawing faint patterns on his alpha’s broad chest with his fingers. “When we do mate.. Did you want pups?” The question was so quiet, it was like he was afraid of his answer.

“I do. I want a family with you. I want to endure sleepless nights just to watch blonde and green eyed little pups grow. I want that as long as you want that.” Midoriya couldn’t help the tears that fell down his cheeks. The wobbly smile that stretched his lips and he hummed in agreement. Katsuki just tightened his arms around his waist and let him cry because he knew he was happy. He had never smelled such pure rich honey from the little body buried into his chest and he felt the swell of pride at being the cause of that.

*****

Katsuki wanted to meet Inko, yes. That was true. However he was not prepared for the anxiety that came with seeking the approval of the only parent his future mate had. Midoriya told him that his mother was a lot like him and that they would get along great, but Katsuki was not convinced. Midoriya even tried to convince him not to wear scent blockers and that was a hard no. Midoriya is the only person he has ever met that has enjoyed his scent. Fresh split blood is not an attractive smell.

He can only imagine the uneasiness it would give his mother to know the person courting her only child smelled like a fresh crime scene. Even through all his anxiety, he was genuinely excited to be granted full permission to complete the courtship. His little omega was everything he could have ever wanted in a partner. 

The Midoriya household was a small house in a residential area of a small town. One of a street line of near identical structures. A simple white door with a light chime of a door bell. 

Almost immediately afterwards the door was slammed open so fast the nob hit the wall hard and bounced back. A short woman with long green straight hair snatched his omega into a crushing hug with a squeal of glee. Katsuki was very unprepared. Midoriya had given him the idea of a soft spoken timid omega but she was anything but, with this impression. 

Katsuki stood like a deer in headlights watching her swing his boyfriend around while he let out that beautiful bell tinkle laugh. Not a moment or two later he was placed back onto his feet and Inko stood back to actually look at him. Katsuki saw the exact second that she registered the collar. Her gaze locking in on the green leather and her hand came up to yank him down to her level. She eyed it closely and he could feel sweat gather in his palms. He tried to subtly wipe it off on his pants but the movement drew his mother’s attention. 

Her curious demeanor shifted to surprise as she looked at him.

“My goodness, you must be Katsuki!” she clapped her hands together. Midoriya’s smile was obviously inherited from her.

“Yes ma’am. I’m Katsuki Bakugo, it's a pleasure to meet you.” he held out his hand in greeting and she completely bypassed it to squeeze him in a bone crushing hug for just a second.

“I’m a hugger, dear. It’s nice to finally meet you as well.” she pulled away and motioned for them to follow her inside. “You’re even more attractive than my little Izuku described.” she gushed as they gathered into the living room. A couch sat across from an older tv and an armchair was placed to the left. She poured them both a cup of tea from the already set pot on the coffee table.

“Mom!” Midoriya cried. His face was flushed in embarrassment and he tried to hide in his jacket, pulling the hood over his head with a groan.

“Thank you.” he smiled politely before giving his omega a mischievous grin.

“I’ve noticed that you're wearing blockers.” man, she did not beat around the bush.

“Yes.” he frowned slightly, trying to figure a way to avoid removing them.

“Is it for a medical reason?” she sipped her tea and he already knew he was fucked.

“No”

“A man of few words aren't you.” she didn't seem upset at all, more of an observation.

“Sorry, I'm just nervous to meet you. I wanna leave a good impression but..”

“But?”

“My scent isn't very pleasant.” he relented, hoping beyond hope that she would leave it like that.

“Oh I'm sure it isn't that bad.” Great, she was just like her son. Stubborn.

“I’d like to keep my blockers on if it's all the same.” he didn't want to offend her, and shot a pleading look to Midoriya who was simply watching the exchange and sipping his tea. He caught Katsuki’s gaze and a small smirk lifted the edge of his lips. He knew this would happen. That’s why he didn't push the topic before they left. Katsuki sent him a small glare and he had the audacity to shrug.

“Nonsense. This is a blocker free household.” she wasn’t having it and narrowed her eyes on him. His anxiety was spiking and he knew if he removed them now smoke and blood would fill the room with his distress. He sighed and swallowed his heart beat.

“Please excuse me. I need to get some air.” he stood up and quickly left the room. 

*****

Midoriya felt bad. He knew how stressful this meeting was for his alpha and how much he didn't like his own scent. It didn't help that every person besides him has hated it. He felt his stomach drop at causing his alpha such distress. He could see the tension in his shoulders as he walked away.

He didn't mean to upset him so much but he really likes his scent and wanted to show him off to his mother. He figured they would argue back and forth for a minute and then he would give in and everything would be fine. He did not see this coming. He didn't need to smell him to see his distress. He whined low in his throat as he closed the door.

“Sweet heart.” his mother called. “Why is he so against taking off his blockers?”

“Sorry mom. I didn't think it would bother him this much.” he knew he was leaking distress and it would pull his alpha back inside soon. “Everyone hates his pheromones. He wears blockers around everyone but me and only when we are alone. I love his scent but he wants to make a good impression and he’s afraid that you won't approve of him because of it.”

“That's ridiculous.” she huffed, but Midoriya just frowned at her before staring down at his cup.

“Is it really that bad?” she asked quietly. She could feel the guilt coming off him in waves. He just gave her a sad smile before the door opened and shut quickly, his alpha returning to him on the couch. But he wasn’t paying attention to his mother anymore, only concerned with the strong distress radiating from his omega.

He took his drink from him and placed it on the table before pulling him into his lap and crooning softly into his hair. His arms wrapped around him to try and calm him but the distress did not waver and after some time passed his alpha was clawing at his cage, demanding he calm him.

He growled in frustration before finally relenting and peeling the clear plastic off his neck and angling his omega’s head to press him into his gland. Within no time burning campfire flooded the room with his calming pheromones and not a few seconds more before all distress from his boyfriend was gone. His body slack against him with his arms still wrapped tightly around him, crooning softly. Midoriya purred back.

“I'm sorry.” he muttered and Katsuki just sighed.

“It's okay. I know you didn't intend for this to happen.” Rubbing circles into his back, he looked up to make eye contact with Inko who was simply observing the exchange.

“The reason that I was so hesitant is because I don't smell pleasant. I don't want you rejecting me because of my pheromones.” 

“Oh dear, pheromones have nothing to do with my approval. All that matters to me is how well you treat my son.” Her smile was warm and inviting. Her grassy lilac scent spread her calming pheromones into the air and Midoriya stiffened. Katsuki looked down at him and saw his disgust. Midoriya didn't like his mother’s scent? Well that made two of them. He didn't want to offend her so he said nothing but his smile was forced and he hoped it didn't look too bad.

“Besides, you smell like a campfire. I don't know why you think you smell so bad.”

Katsuki did grimace this time.

“That's not my neutral smell.” he took a deep breath and just let it go. Immediately the fresh spilt blood he had been repressing flooded the room and his campfire merely lined the edges of it, an afterthought. He watched as she had the same reaction as every other person he had ever met. Her face scrunched and her eyes watered. He pulled it back in and replaced his blockers.

“That’s why I don't take off my blockers.” he sounded so resigned and disappointed. Inko had a long running promise to herself never to lie to a loved one and it pained her to admit that his scent was revolting to her. The thick iron stench had overwhelmed every other fragrance in the area completely and made her stomach roll with nausea. 

It was Midoriya's turn to comfort his alpha and he cradled his face into his shoulder. Releasing his own honey misted rainforest scent to calm his nerves and silently reassure his mate that he was not going anywhere. Katsuki nuzzled into him and just blocked out everything but his calming pheromones and the gentle fingers threading through his hair.

“Sorry, mom. We're going to go up to my room for a bit.” he stood and guided Katsuki up the stairs, not waiting for her response. But what response could she even give him. Her son had chosen an alpha who obviously cared very much for him. He was handsome and everything exuded prime alpha but his scent was nauseating. Her son had the complete opposite reaction to her own. When blood filled the air she was disgusted whereas her son relaxed even more into his hold and smiled at him. The love she could see in that moment solidified his place in her family but he had to wear scent blockers. She wished she could have said that his scent was pleasant but that would be a lie she would not even be able to fake.

She sighed and cleaned up the few cups, bringing the tray to the kitchen.

*****

The two adults crammed into the small twin sized bed and kept pressed together. The burning rainforest scent that leaked into the room surrounded them and calmed them into a hazy comfort.

“We’re going home tomorrow.” Midoriya whispered against his hair. He was sad to not spend time with his mother but his alpha was his priority right now and she could wait. 

“Are you sure? I know you miss her. You can stay if you want. I won't make you give up time with your mother.” he rubbed his back and nuzzled into his neck.

“I’m sure.” he kissed his crown. “This is partially my fault but I would still feel better just staying with you in the dorms. Give my mom space to process on her own.” he mumbled. “I don’t like the way she reacted. I'm a bit insulted honestly.” he pouted.

“Babe, I knew she would, that's why I wanted to just wear my blockers. If anything it’s her fault for pushing so hard.” he chuckled at his feisty omega. “If you would rather go back to the dorms that's totally fine. As long as I get to be with you, I don't care where we go.” Midoriya giggled.

“You're such a sap.”

*****

Spring break was a routine of snuggles, movies and random dates that Katsuki enjoyed springing on the omega. The current one had them perched at the edge of a cliff overlooking brilliant forests and mountains.

“This is beautiful, Kacchan!” he gushed. He had complained the entire hike up the mountain but all his fatigue drained from him at the gorgeous sight. Clear blue skies and only a slight breeze to ward off the melting sun made for a perfect day to go on his favorite hike. No matter how much he complained and whined, Katsuki was proud of him for actually making it, besides his omega hadn't been getting enough sun recently.

"was it worth the hike?" he grinned, wrapping his arms around his waist.

"yes, I'm sorry I complained so much." he smiled. 

The wind was only a soft breeze that swayed their hair like leaves and brushed their skin like a ghost of a touch but it made the moment really special. Away from everything in the city. All the cars and people were replaced by rustling leaves and calling birds. Midoriya never felt so free. His only real hold on reality being the strong arms of his alpha wrapped possessively around his torso. 

He never felt so happy and it was all thanks to this gorgeous man who decided that he was worth it. 

Midoriya turned in his hold and cupped his cheeks. The warmth tingling his fingertips and rushed heat down his arms to settle in his chest.

“It's so quiet here. Like there's no one in the world but us.” he whispered.

“I know. That's why I like coming here.” the blonde grumbled, nosing at his jaw and neck before planting a kiss on his scent gland. 

Midoriya was typically a very straight laced omega. Never tried any popular drugs and not fond of alcohol. He never broke the rules and never did anything really spontaneous, but right here in this moment, with this gorgeous hunk of an alpha, he craved to be a rule breaker. And what better way to start than public sex.

The thought of getting dicked down by his alpha right there in broad daylight, with no coverage sent a thrill down his spine. His shorts began to feel damp with his slick and his boyfriend growled.

“What are you thinking about that would make you slick so quickly.” His voice was husky and deep, rich with lust and heavy with desire. His large palms slid down his waist to cup his ass and press the omega’s erection against his thick thigh. Midoriya moaned softly against his shoulder.

“Kacchan” he breathed and Katsuki pulled back to look at his omega. “I want you to fuck me right here.” he punctuated his desire with a bite to his ear lobe, pulling lightly with his teeth. Katsuki growled, biting his shoulder before coming up and gripping his jaw, pulling his face to kiss him. Katsuki held the omega by the back of his neck as he thoroughly wrecked him with just his tongue, teeth and lips. 

When he finally released him, Midoriya was gasping and moaning. His back came in contact with harsh tree bark and he winced just slightly. His alpha was hyper alert of any distress and pulled his thick sweater over his head and slipped it over the omega instead providing a cushion between his back and the rough bark.

The strong iron of blood and thick smoke of campfire surrounded him and he moaned loudly, arching his chest into his alpha’s hold. His arousal spiking with the rush of pheromones, hips flexing for contact. His head was so fuzzy he didn't even notice when his shorts and underwear were removed but he did feel the fingers that entered him slowly. 

“Kacchan!” he cried, the steady stroking against his insides pulling him deeper into his aroused haze, and all he knew was pleasure. The deep groans and growls from his alpha only stoking the fire and making his need grow unbearable.

“Alpha, please” he gasped, red eyes catching his own, waiting for him to speak, to ask for what he wanted. “Please, inside, I need you.” he sobbed, wanting to be filled by the thick cock that was rubbing against his ass as his alpha prepped him. His desire unable to be contained and leaking in fat tears of frustration down his cheeks.

“Izuku, my omega. I love you.” Katsuki murmured against his lips before claiming them in a deep embrace. He pressed inside slowly and the stretch was nothing but pleasurable. His craving was finally fulfilled and he cried with happiness, feeling his cock so deep inside.

“Kacchan! So good!” he moaned and Katsuki growled loudly as he bottomed out. Midoriya was about to be fucked against a tree in the middle of the forest and he had never been so turned on. The possibility of being caught in such an obscene manner stirred something inside him and he rolled his hips the best he could with the little room he had.

“Move, alpha. Fuck me hard and fast.” Midoriya could see his red ears and feel his hot breath against his throat before a feral growl vibrated from his alpha’s chest and Midoriya was jerked up straight and balanced against the trunk higher again before Katsuki pulled half way out and slammed back inside. The omega shouted in ecstasy, every harsh thrust hitting that deep bundle of nerves and sending crashing waves of bliss.

His slick poured out of him, wetting the soil under his feet and making wet slaps everytime the blonde’s hips made contact with his flushed ass. He wasn’t going to last. The overpowering heat and constant shocks of pleasure coursing through his blood sent him rushing to his orgasm.

“Alpha, I’m ...gonna...ahhhhh” Midoriya threw his head back with a scream as his orgasm rocked through him, blurring his vision and making his limbs tremble. The gush of slick that erupted from deep inside and the sudden pulsing around the alpha’s cock pushed him over the edge and he thrusted hard and a rough groan, his knot locking them together. 

They gasped for air. Panting hard against each other’s chests. Midoriya’s legs had a solid lock around the blonde’s waist and his hands fisting those soft blonde spikes. He wasn't sure when his hands grabbed his hair or when he latched his legs around his waist but as he came down from his high and his senses returned to him his blush bursted hot on his cheeks.

“I'm so sorry.” he squeaked, releasing his tight hold and rubbing his fingers softly over his scalp in apology. Katsuki chuckled.

“Who knew that innocent little omega Izuku would beg to be fucked in the middle of a forest.” he cocked an eyebrow at his boyfriend, that sharp smirk sitting on his lips.

“Oh shut up. Like you didn't enjoy it.” he grumbled, puffing his cheeks.

“Oh, I enjoyed it, trust me. However your legs locked around me and forced me to knot you.” he patted his thigh lightly. “So we aren't going anywhere for awhile.” His grin was full of so much self satisfaction that it pulled a giggle from the greenette. The giggle turned into a chorus of laughter from them both that echoed in the valley. Midoriya’s bell-like laughter cut off suddenly.

“You okay?” Midoriya was stark white.

“Our laughs echo.”

“Yeah.”

“That means that...when I..during the...the sounds.” he whined and Katsuki erupted in laughter.

*****

“Izuku, your collar is gorgeous!” Ochako beamed. Classes have begun again for the new semester and Midoriya has received nothing but compliments on his collar. Even people he had never spoken to before gave a passing compliment and it filled his alpha with pride. Just like before the break, Katsuki was still attached to him at the hip. His arm wrapped possessively around his waist and his smug smirk now has permanent residency on his mouth. 

“Thank you, Ochako.'' His smile was genuine. After so many compliments his response and thank you became automatic but Ochako was his best friend and his chest swelled with affection. He leaned back into his alpha’s chest and strong arms wrapped around his waist from behind.

They sat at their usual place in the library, their planners open to compare schedules and make new study dates.

“Hello.” Todoroki greeted, his chair squeaking slightly against the floor. He froze slightly as he was sitting as his eyes landed on the green collar. Slowly he sat down and opened his notebook as well. 

“Hi, Shoto!” Midoriya and Ochako greeted while Katsuki merely nodded his head to make his omega happy, playing nice with his friends. Todoroki frowned as he extracted a pen, clicking it repeatedly.

There was a tension in the air as Todoroki was silent. He was the first to not comment on Midoriya's new collar. 

“So Shoto, what do you think of Izuku’s new collar?” Ochako asked, attempting to break the silence but the tension only grew suffocating. He looked up at her before slowly looking back at the collar. His lips thinned and his eyes narrowed in the most expressive face the blonde had ever seen.

“Looks cheap.” he noted and returned back to his notes. Katsuki growled, thankful for his blockers that held back the violent ash that would have spread through the room. No one paid attention to his reaction though as Midoriya and Ochako stole the show. 

“Shoto!” Ochako snapped in both surprise and outrage. But the flood of distress and hurt that filled the air, called even the attention of the surrounding students. Even the quiet chatter died completely, the only sound echoing in the silent room was the sob that tore from the omega before he stood and walked away. His alpha picking up their things and turning back to make eye contact with the brunette beta. They had developed a strange relationship through the mutual care for their green haired companion. She understood without words and took a deep breath before he ripped off his blockers. 

The full force of his anger poured through his skin in waves of ash and blood. Todoroki’s eyes widened before he bared his neck on instinct and he went green. His eyes pouring tears from fear or disgust he didn't care.

“You best fucking apologize, you peice of shit. I don’t give a flying fuck if you don’t like me but he’s supposed to be your friend. If you care about him then you should support him in what makes him happy not throw out such fucking petty and hurtful words just because he rejected you. If you can't handle being around us then stay the hell away from him.” he growled dangerously before slapping his patch back into place and stomping off to comfort his omega.

Ochako stood as well letting out her deep breath and covering her nose in her scarf to protect from the violent scent that was still fading. She looked at her friend and she hoped her sadness and disappointment was comprehended before she took her leave without a word said.

*****

Midroiya never felt so hurt. Todoroki was supposed to be his friend. For him to say something so mean and unwarranted just because he could, hurt . It hurt so bad. His tears continued to fall as he headed for his dorm. He left without checking for his alpha to follow but he knew he would. His alpha would always follow after him. He actually cared about what he thought and what made him happy. 

It wasn't long before strong campfire enveloped him and his tears slowed. His harsh sobs caught in his throat and turned into small sniffles. He was pulled to a stop and brought into his boyfriend’s chest. Deep rumbling croons whispered softly against his hair helped pull him away from his distress until he finally calmed down. 

“It’s okay, baby.” he was so soft, handling him with such care and compassion. Not telling him not to cry and letting him feel, only whispering comforting words to help him through it. 

“I want my nest.” he croaked.

“Okay, let’s go to your nest then.” 

*****

Midoriya has not forgiven Todoroki in 3 months. Not since the library incident. He had found him a few days later and apologized but his words cut deep and Midoriya could not forgive him so easily. Midoriya spent most of his time with his alpha and Ochako now even sometimes with Kirishima, a red haired alpha that had become friends with Katsuki through mutual classes. 

Kirishima was an interesting character. Definitely a muscle head with an overly friendly personality that had somehow grown on the blonde. They were currently at a movie night in the red haired alpha’s dorm room. He had insisted on introducing his omega to them.

“He’ll be here soon.” his grin reminded Midoriya of the sun with how blinding and constant it was. The man never frowned, there was the rare neutral and the contant happy aura was very pleasant. His lighter ocean breeze scent was easy on the senses and tolerable to both parties.

“He?” Midoriya asked, lighting up at meeting another male omega.

“Yeah, he’s not from here. Lives two hours north and only comes down a few times a month for me.” his fond smile softened his sharper features and Midoriya smiled in return.

“Well he better hurry up, I'm bored.” Katsuki mused. 

“I’m here, bitches!” the door slammed open to reveal a blonde with slightly longer straight hair and an outfit of mismatched patterns.

“What the fuck are you wearing?” was the first thing that Katsuki said. Sitting straight from his lounging on the floor. His eyes were burning from the disgusting apparel. As a child raised by fashion designers this was a crime against humanity. Kirishima laughed loudly, tears clinging to his lashes in mirth.

“How dare you, sir. This is art.” he snapped his fingers before kicking the door shut with his heel and plopping down in Kirishima’s lap. His beefy arms wrapping snug and he nuzzled into his neck. 

“It’s disgusting. Where did you even get those.” he jabbed his finger at his pink zebra print felt pants.

“Oh these are my friend Mina’s. She has a gift for finding this style.” he stretched his leg up proudly. Katsuki gagged and pulled his omega into his lap to distract himself. Midoriya giggled through the whole ordeal, a shriek of laughter escaping as he was pulled into his lap.

“Oh you must be Midoriya. I’m Denki.” he offered his hand and Midoriya grasped it firmly.

“Call me Izuku. I’ve never met another male omega.” he grinned. 

“Oh yeah, me too. How long have you been with mister grumpy?” he asked.

“Kacchan‘s been courting me for over a year but we’ve only been dating for about 8 months.”

“What?” he gasped in shock and Midoriya jumped in surprise. 

“What?”

“You guys aren't mated yet?” He looked a mix of horrified and confused.

“No..” Midoriya said quietly and glanced back at his alpha that was now giving his undivided attention to the other omega.

“Are you two mated?” he asked. Kirishima lifted his face for the first time and beamed wide.

“For the past 2 years.”

“How old were you?” Midoriya asked, eyes wide in wonderment.

“We were both 18. We courted for I think 4 months?” 

“5 month, Kiri.” Denki corrected. Midoriya was shocked.

“So soon.” 

“Well yeah,” Kirishima grinned. “When you find your mate, you just know.” 

They shared a look and kissed. Midoriya stared down at his lap in thought. He wondered why Katsuki hadn’t asked him to mate yet. He did not doubt his desire but maybe he was afraid he would reject him. He already got his mother’s permission. After that disastrous first meeting she had reached out to him to apologize and expressed her happiness for them. 

Midoriya knew he wanted to mate with Katsuki. The blonde had proven time and time again his love and affection. He wanted to be with him. He wanted to be his husband and carry his pups. He wanted to raise little blonde pups alongside his gorgeous mate. He wanted him.

“Babe?” Katsuki called.

“Huh? Yeah?” Midoriya cocked his head to the side to see his worried mate.

“You okay?” Midoriya smiled.

“Yes. I’m great.” 

*****

Midoriya gasped awake. His back arching off the bed and a deep groan echoing from his throat. It was here. He was in heat. He reached a shaky hand to his night stand and managed to hit his speed dial. His phone read 2:38 am. It rang twice before the groggy voice of his alpha rumbled through the receiver.

“Izuku?” Midoriya whimpered. “Babe? What's wrong?” his voice filled with worry, his concern rocketing.

“M-my heat.” a throb vibrated his body and tore a cry from his lips. “Help me.”

“I’ll be there in 10 minutes.” the line went dead and Midoriya cried. His omega was calling for his alpha tearing at its shackles and ripping all the strength from his limbs. He couldn’t track how much time passed as he writhed in his bed but his skin was sticky with sweat and the cold air of his dorm chilled his bare skin. It was his first real heat. He needed his alpha. 

After so many years of faux heats before he lost his virginity, this was the first that his body felt the deep ache and craving for cock. His vagina pulsed and dripped with slick, ready and waiting for his alpha.

Another wave of ache passed over him and he whined low. His door banged open and he looked up through blurry vision to see a silhouette of spiky hair and red eyes reflecting off the moon standing in the doorway. 

“Izuku.” he growled, hot campfire and blood filled the room and sent a cry tearing from his lips.

“Kacchan, please.” he begged and his alpha’s arms wrapped around him tightly.

“Tell me what you need.” he pleaded. He would not take advantage of his omega in such a state. Even if his alpha was rattling his cage and screaming at him. He brushed his sweaty hair from his forehead.

“Please...please..”

“use your words, please Izuku” he whimpered at the pain his omega was enduring.

“Mate me.” he pleaded and Katsuki’s heart swelled.

“Are you sure you don't just want me to get you through your heat?” he asked, his thumb stroked his cheek before searching his eyes for any hesitation.

“I love you Katsuki...please..mark me.” Katsuki didn’t hesitate to embrace his omega. He stripped his clothes quickly and laid himself over the smaller body. Pleads and whines falling from his lips with every brush of skin and whaft of his alpha’s aroused scent. 

“Kacchan, now please. No prep.” he gasped as two fingers entered his sex.

“Fuck you’re so wet.” he pulled away from him to grip his base and pushed his tip inside. A scream of pleasure echoed around the room as he thrust to the hilt.

“Move, please!” his back arched high, his hips flexing to keep him as deep as possible. His body arching naturally to meet his alpha’s thrusts. Hot lips covered his own to muffle his screams. Midoriya's nails scraped and clawed at his back urging him to mark him in any way he could.

Every harsh thrust deep inside twisted that coil tighter and tighter. Aching on the edge of release but nothing was enough.

“Kacchan, please.” he begged, choking on a wrecked sob. Tears flowing down his flushed cheek, leaving chills down hot flesh. His neck pulsed with his desire to be marked and he bared his gland to him. Open indisputable permission to claim, to mate. His omega was begging and pleading for it, for him.

Katsuki groaned deep, falling down to his forearms. His claiming canines lengthened and dangerous, dripping in bonding fluid. Midoriya exposed his own smaller fangs, bones aching to drive his teeth into his flesh. He stretched his jaw over his neck, his hot breath fanning the skin before a small poke then searing pain erupted in his shoulder. He screamed in pain and buried his own fangs deep in his alpha's opposite gland. The pain faded immediately and was replaced with scorching hot pleasure launching him over the edge into orgasm. His alpha thrust deep into his warm heat one last time before his knot locked them in place. 

They panted harshly with the sheer exertion of energy the bonding pulled out of them. Their teeth still dug deep into the muscle. Slowly Katsuki pulled his fangs away and they shrank immediately to their normal size. Midoriya followed soon after and he could feel Katsuki’s love, swirling like an endless vortex in his chest, barely able to be contained.He cupped his face with shaking fingers and gawked into those deep blood red eyed that he so adored. They were so soft, so fond of him. 

This man who chose him out of all the omega he had ever met. He chose him. He felt fresh tears stream down his face and watched matching ones drip from his lover like a mirror of emotions. They were connected. Through the bond they both wore. A mutual decision made in love and trust during his most vulnerable time.

“My alpha.” he whispered.

“My omega.”
