Work Text:
It was early afternoon on a Friday and Shinso was running on schedule. Class had only gotten out ten minutes ago yet he found himself back on the training fields of U.A, sparring with Neito Monoma.
It was part of a pact they had made at the beginning of the year, both boys were terrified of failure but could only seem to admit it to each other. So they practiced in secret. It was a win-win situation, Monoma got time to practice with his quirk, and Shinso got time to fight against a variety of abilities.
Most days they engaged in hand to hand combat, while other days he would try out a new trick he learned with his capture scarf on Monoma. Either way, they met up every other day in the open pastures surrounding the schools and practiced.
Recently, as hotter months approached, less and less students wanted to be outside, which gave them more privacy. Large oak trees surrounded them and gave shade while dew still stuck to the green grass below them. Crickets and cicadas sang in the background of their grunts and heavy breathing.
They were mid combat when Shinso knocked Monoma to the ground, he hit his back hard against the dirt and threw his head back. Shinso expected him to get back up, to use Shinso’s hesitation as a tool for a counterattack, but the blond stayed on the ground, his chest heaving.
It caught him so off guard, watching him just give up on the ground, that he knelt down to his side. The grass was warm and wet which left the residue of mud on his knees. Monoma’s eyes were slightly out of focus, he was staring up at the sky.
“Something wrong?” Shinso asked.
“I just— I just need a minute,” he said between heavy breaths.
Hitoshi stood up to grab his water bottle from beneath a tree, thinking he was just dehydrated and tired beneath the blazing sun. He picked it up and walked back over to his side, handing him the bottle.
Monoma, almost aggressively, took it from him and chugged the water until it was empty. When he was done he threw it to the side and went back to laying down.
Shinso was completely and utterly confused, but as he thought more and more about the past ten minutes he had to admit, Neito had been acting weird all afternoon. He had been impatient with him the moment they met up at the field, his movements had been jagged and sloppy, but Shinso found himself blaming it on the heat. As time went on it became increasingly apparent that the weather wasn’t the issue.
”Are you sure everything is alright?”
“Just leave me alone! Okay? I don’t need help, especially from a Class A kid… I’m going home.” He slowly managed to stand up, albeit his movements were wobbly at best.
Shinso couldn’t do anything else but watch his back as Monoma walked off towards the dorms. Something was definitely wrong, it was one thing for the blond to be snappy at times, but it was another thing for him to outright insult Hitoshi, something he never did.
Neito had made his relationship with Class A very apparent since the moment Hitoshi joined the hero course. But there had always been this quiet truce between the two ever since the joint training they did when they were first years that Hitoshi was the exception to his Class A hatred.
The two had a rough patch when it was confirmed that Shinso would be joining Class A instead of B at the beginning of their second year, but he assumed that conflict was long behind them as third years. There must still have been some resentment laying dormant inside Monoma’s mind this whole time.
Begrudgingly, he grabbed his water bottle and noticed Neito had left his book bag in the grass. How the blond had managed to forget it, he didn’t know, but he was so off put while stomping back to the dorms, Shinso couldn’t imagine it as impossible.
So he grabbed it and slung it across his shoulder before heading back to the dormitories. Both Class A and B’s buildings were a short minute walk away, so it wasn’t too much of an inconvenience for him to just stop by and drop it off for him. As he walked back, he thought more and more about the past ten minutes. They hadn’t even been out there for long, so it was strange for Neito to already be so exhausted.
Some might call it unconventional for an Alpha and an Omega to fight on par with each other, but far too many people underestimated Monoma. He was quick and smart, which made up for the fact he was a half foot shorter than Shinso and a few pounds lighter. Something was always going on behind those blue eyes and Shinso loved to pick his brain, whether it was battle strategy or just small talk, the Omega always surprised him with whatever came out of his mouth.
When they were fighting that day there was definitely tension in the air, but Shinso just labeled it as Monoma wanting to win, like he always did. But maybe it wasn’t tension he was noticing, but something sweeter. He stopped walking and held up Monoma’s book bag, his scent was thick on the fabric.
He suddenly felt so stupid; even though it was stupidly hot outside, it was still spring, which meant it was still mating season. Monoma was in heat.
Once Shinso noticed his scent he felt like it encompassed his very being, it had been all around him the whole time, even when they were sparring. At first smell, Neito’s scent was lemony and sour, but soon melted into that of a lemon cake. Something warm that reminded him of home.
He found himself salivating while standing there before snapping out of it. Shinso couldn’t say he was a typical Alpha, he lacked the possessive urges that people like Bakugo had, but he still had the frame and biology of one.
No matter how much he respected Monoma as a person, and as an Omega, he couldn’t ignore the desires he was born with. He walked faster, thinking if he moved his body the dirty thoughts plaguing him would subside but they only grew as he got closer to Class B’s dorms.
Green grass turned into concrete beneath his feet as he walked up the front steps. The cool AC inside hit his face, causing him to realize how hot his body felt. A few students sat out in the living room, drifting between the couch and kitchen. He waved at Shoda, who was playing a video game on the TV, and prayed he didn’t notice his own pheromones he tried so hard to contain.
Monoma’s dorm room was on the second floor, which gave him a moment of rest in the elevator before he had to confront him.
Shinso had gone through ruts before, but since he was just a teenager they were always spent alone in his room. He never minded only being able to pleasure himself, uncharacteristically, he found himself not wanting to burden an Omega with his urges. Ever since he was a kid he was quiet, partially due to being shunned by society, partially due to his own personality, so part of him enjoyed being in charge of his own anatomy. But Monoma had turned everything he knew about himself on its head. He found himself craving his touch, yearning to know what the Omega would look like below him.
It was like he was being torn apart from the inside. One side of him felt guilty for thinking about Monoma that way, knowing it was wrong and an intrusion on his privacy, while another side of him tried to convince him it was his right as an Alpha to feel the way he did. The discord in his head didn’t stop once the elevator opened on the second floor.
He hurried outside once he noticed Kendo staring at him from a bean bag next to Tetsutetsu. She raised an eyebrow at his presence but quickly let it go and went back to the card game the two of them were playing.
Neito’s room was just down the hall but he couldn’t help but stop before reaching for the doorknob. He rested his head on the wood of the door and against his better judgement, opened it.
The scene that laid before him is exactly what he should have expected, yet he still found himself taking a sharp breath.
Monoma had turned his bed into a nest, pillows surrounded him in a circle that outlined his body. His face was buried in a pillow and his hand was beneath the waistband of his pants, his breathing was so loud that he didn’t even hear Shinso walk in.
He whimpered while his arm made jagged movements beneath his shorts. Shinso wanted to know if he was fingering himself or stroking himself, he wanted to know what made him moan and jerk, and how he could replicate it.
Every neuron in his body was telling him to pounce, to take what was his and relish in everything that came with it. Somehow, he managed to gently set down his bag before giving in, which made enough noise for Neito to look up in embarrassment.
“Hitoshi? What are you—?” His voice was soft but his blue eyes went wild at the sight of the Alpha.
Shinso was on him before he could finish his sentence, straddling his hips.
“You—fuck— you left your bag.” He looked over at it, sitting on the floor next to the bed.
It was so hard to make conversation when all he wanted to do was rip the Omega’s clothes off, but his self discipline ran strong in his veins. He noticed Neito’s right hand, he had pulled it out from his boxers and slick coated his fingers, practically dripping onto the floor.
“Yeah?” They were both panting.
”Do you normally spend your heats alone?” He asked and immediately regretted it as he watched Monoma’s face cringe.
“I don’t want people acknowledging I’m an Omega, you can go now.” He pushed Shinso off of him and went back to cuddling a pillow.
“Don’t be like that.” Shinso had thrown out his voice of reason the moment he saw Monoma laying in his bed, legs slightly parted as he touched himself and moaned into his sheets, it wasn’t right for an Omega as pretty as himself to spend his heat alone.
“Be like what?” Neito said, even his voice turned Hitoshi on.
“Stuck up, arrogant, egotistical, narcissistic, acting like you’re better than everyone else.” He crawled back onto the bed without complaints.
He smelled so fucking good, Shinso wondered if he smelled better beneath his clothes.
“You’re in heat, Neito, let me make this easy for you,” he added, lacing his voice with the pull of his quirk.
It obviously worked because Monoma let him lay on top of him again.
”How long has this been going on?”
”Stop acting like you care, just hurry and satisfy yourself already.” He bit back with that signature scowl.
“You know I’d never do that to you.” He traced a hand down his jawline, absolutely captured by his beauty.
The blond could only look away at his words because he knew they were true.
For some reason, he liked that Monoma was playing hard to get. He liked that even in his state, he was still the same bastard who could talk back to anyone.
”I want to help, that’s all.” It was like a game, how many walls could Shinso break down in Monoma’s mind before he finally gave in?
”F—fine.”
The air in the room was thick with the smell of lemon and Shinso’s own scent; something close to dark chocolate. Not to mention the subtle aroma of Monoma’s slick.
Their first kiss was hesitant at first, but soon melted into something hot and passionate. They both quickly realized how badly they needed this, how badly they needed each other.
Shinso knew the way Monoma’s head worked better than anyone else, he could anticipate a thought or combat move a mile away, which only made this all the more easier. Their bodies rocked against each other in sync, weirdly similar to the way they did when they sparred.
Everything became too hot to bear so Shinso quickly pulled off his shirt and discarded it on the floor. When he pulled away, Monoma was a dazed mess of drool and sweat running down his face. It was kind of cute.
He softly nudged the blond to sit up so he could pull his own shirt off, they were both still wearing the dress shirts that went with their uniforms. He cradled Monoma and set him back down on the bed.
”Please,” he whined, “my pants.”
It was shocking to hear the normally confident Omega talk in such a pathetic tone, he couldn’t think of a single instance in which Neito ever said ‘please’ to someone. But these were different circumstances and both boys’ heads were thick with the fog that came with mating season.
Immediately, Hitoshi complied. He pulled off his shorts along with his own before adding them to the pile with the rest of their clothes.
They made out in their underwear until the wetness leaking through Neito’s boxers became too great to ignore. Shinso planted kisses down his neck, stopping to suck against his earlobe, before continuing down his torso.
He stopped at his chest, teasing Monoma’s nipples with his tongue, flicking at them until they hardened at his touch. Every little movement he did sent shockwaves through the blond’s body, his back arched higher with every kiss. Who knew it was this easy to watch the infamously cocky Neito Monoma unravel.
He inched his way down his body until he reached the waistband of his boxers, nudging his face against the hard bulge inside them. Neito moaned at the teasing, his voice high pitched like a cry.
“Please, please Hitoshi, I need it.” He begged.
It became extremely evident that Monoma had never spent a heat with an Alpha before, which Shinso almost found shocking. There were a handful of other Alpha’s in Class B, and Monoma—in Hitoshi’s opinion—was the hottest looking Omega in their grade, so it was strange that he never let one of his classmates satisfy him while going through a heat.
But when he thought back to what he had said only minutes before, “I don’t want people acknowledging I’m an Omega”, everything started to make sense.
He pulled his boxers off and this time gently set them down, the smell of them only made his conscious slip even more.
Neito’s cock was wet with slick and even more erect. Hitoshi pulled his legs apart and forced him to spread. He only stopped to stare at his leaking pussy for a moment before deciding it needed to be filled.
The Omega was too flexible for his own good. He melted into whatever position he was asked of all while purring. Hitoshi, slowly, edged the sides of his hole, feeling the wetness that had been building up with two fingers.
He looked upwards to watch Neito’s face contort from the contact. His brows were knit in concentration and his mouth was slightly open, soft pants escaping.
“I’m sorry you’ve been having to go through this alone.” He murmured before pressing a kiss against his inner thigh.
“I— it’s fine—, please, Hitoshi, I can’t—.”
“—Yes you can, baby, just breathe.” He took that as his queue and slid his middle and ring finger inside, gently massaging his inner walls before reaching his swollen clit.
For some reason, pleasuring Monoma was like second nature for him. His fingers slid so easily in and out of him due to the excess amounts of slick dripping from his entrance.
Moans filled the room as he quickened his pace. He scissored his fingers inside him, making sure he was nice and loose before filling him with ten inches of cock. Shinso moved his face from between his legs to eye level with the Omega, all while keeping his fingers pumping inside of him.
He was even prettier up close. His blond hair framed his face and fell around him, his pink lips wet with drool and slightly parted as he moaned and whimpered, and his light blue eyes flashed with pleasure every time Shinso curled his fingers inside him.
“I need you inside me.” He took a big, shaky breath. “I need you to breed me.”
“I wish I could, pretty boy.” He moved some of his blond hair out of his face. His pussy was so warm and supple, it would be so easy to fill him with pups.
Once his fingering had warmed up Monoma’s leaking pussy, he pulled them out. When he did, Neito cried into him, wrapping his arms around his back and clawing into the skin.
“No! Put them back in and don’t take them out until I come!” He demanded like the brat he was.
Shinso hoped his nails would scar down his back, leaving him with something to remember this evening by. His groans only made marking him even more of an appetizing idea, it wouldn’t hurt, Shinso thought, it would fade over time, anyway, he reasoned with himself. The Omega whined like a child that had its toy taken away, but it couldn’t have been easy for him, especially with Shinso making him teeter on an orgasm for so long.
He let Monoma watch as he pulled his own boxers off, doing it excruciatingly slow just to tease him. His cock was already hard when he threw his remaining clothes to the side. He wondered if the blond had ever thought about how large he was, sure, they had showered together after practice, but they never faced each other. So the Omega only had shadows and glances to go off of.
He positioned his body over him, spreading his legs even further, and let his hard cock enter him. He started hesitantly but immediately thrusted his entire length inside him once he felt the tightness of his ass around his girth. At first, he thought it wouldn’t fit, but Neito was so easy to stretch out.
A satisfied moan left Neito’s mouth while being filled, he had been waiting his whole heat for this very moment.
Thrusts turned into glides as thick layers of slick coated his dick. The Omega’s eyes rolled back and he moved his hips in sync with him.
Tears threatened to well up in his eyes from overstimulation, but Hitoshi continued anyway, if he did decide to cry, he would kiss each tear that fell down his beautiful face. Neito’s nails finally drew blood on his back and Hitoshi reveled in the feeling, only wanting to mark him even more.
If he left a temporary mark, other Alpha’s would know Neito was his, but did Neito want that? To be held down as just another marked Omega? He was begging to be bred but that wasn’t him talking, it was the pheromones. Shinso was smart enough to know that.
“Good boy, that’s it,” he said, cooing right into his ear.
He felt his own climax building inside of him, hot and heavy in his lower abdomen. If he couldn’t mark his Omega, he could at least fill him with his cum.
“Hitoshi.” He bucked his hips a little harder every time he said his name. “I need you to fill me, and mark me.” His words mixed with high pitched whimpers.
Shinso buffered off his rhythm, luckily, not enough for Monoma to notice. He wondered if Omegas could read minds, or maybe it was just that the two of them were so interlinked he didn’t need to, he just knew.
“Are you sure, baby?” The pet name rolled off his tongue like silver.
“Yes! —ngh— please, I don’t think I’ve ever wanted anything more,” he begged.
The Alpha’s cock pressed deeper inside his pussy, causing him to shudder in arousal as his g-spot was pounded over and over again. Harder and harder because he knew he could handle it.
Neito’s back arched hard. “Fuck!” He cried and threw his head back against the mattress.
It was like déjà vu watching it happen, because he had done the exact thing only hours before on the fields when they were training together.
His cum spewed all over both of their stomachs. The squirt was warm and smelled like his scent. Before he could think, Hitoshi was already licking it up from his body, continuing to thrust inside him. Even after the Omega came he was still waiting on his own orgasm, he kept bucking his hips inside him, sidelining the fact that it might be too much for Neito to handle.
A few seconds later his vision rolled to the back of his head and he saw sparks as he came inside his Omega’s pussy, his thrusts only sped up as he chased the feeling.
He growled and pumped the rest of his cum inside Neito until he was satisfied. The blond’s lips were slightly upturned and his eyes were closed shut, reveling in the warmth blossoming inside him.
His entire body felt like it was being hugged from the inside, a tight squeeze causing all his muscles to cramp. He wanted to keep riding on that high all night.
With the smell of Monoma’s scent blocking the Alpha’s brain from thinking, Shinso bit down against his scent glands, the soft skin between his neck and shoulder, drawing blood and causing the Omega to shriek in pleasure. The process was primal and messy, their aromas mixed in an instant before Hitoshi drew back. He licked his canines and tasted the sweet lemon cake he had been craving all evening.
He let himself collapse on his back, side by side with Neito, catching his breath. They both stared at the ceiling in silence, only the sound of their panting and the Omega’s purring filling the room. He had opened his eyes and was staring at Hitoshi, sharp blue eyes locked on him.
Even though he couldn’t see him, he could feel his eyes on him. Shinso turned his head to the side to face him. Slightly startled at the sight of his wide eyes already looking at him, the blue was blinding.
“Again,” he said with his signature maniacal smile spreading across his face.
“What?” Shinso was still catching his breath.
“I want to go again,” he repeated, his tone a little firmer.
“I didn’t know you were the one calling the shots now?” He stared at his fresh mark already taking shape on his neck.
“You didn’t fill me enough, I want to go again.” He forced Shinso to look at him.
It was then when he realized Monoma was serious.
“Baby…” Against his better judgement, and all the sex ed lessons he had been taught on teen pregnancy, he couldn’t help but want it as badly as Neito did.
The Omega pouted and Hitoshi knew he was screwed.
────୨୧────
The sun had already set when both of their stamina finally ran out. Monoma must have finally been satisfied because after their last round because he cuddled into his Alpha’s side. Shinso quickly wrapped himself around him, rubbing his back with a free hand.
Cum and sweat stained the sheets beneath them and the thick smell of both their scents filled the room. It had gotten pretty stuffy in the Omega’s room but they were too exhausted to care.
Bite marks dotted Neito’s body, including the initial mating mark his Alpha had left on him, none of the other marks drew blood like that one did.
After letting the blond rest for a while, Hitoshi decided it was time for aftercare. Carefully, he sat up and caught Neito’s attention.
“What’re you doing?” He muttered.
“Getting you water.” He replied, grabbing his water bottle from next to his book bag and going to fill it up in the bathroom sink.
From the bed, Monoma watched him unscrew the lid and hold it under the sink. It filled quickly and he walked back over to his side. His Alpha lifted his chin and let him drink from his bottle. This time, unlike out in the field, he sipped carefully and slowly.
“Good boy.” Shinso said while pulling it away from his lips, a string of saliva breaking between him and the nozzle.
He set the bottle back down before turning back towards him.
“You need some fresh air.” He cupped his face.
His Omega rubbed his face against his palm, marking his territory and spreading his scent across his skin. Hitoshi smiled while watching him. He couldn’t remember a single time when he had seen Neito in such a vulnerable state, he was just glad he could be there for him.
It comforted Shinso to know that he had been his first time, that nobody else had taken the pleasure before him.
“C‘mon, do you need help getting dressed?” He asked while picking up his own discarded clothes.
Monoma just groaned in response, he was trying to sit up but wasn’t getting very far.
“Hey, hey.” He hurried to his side. “I’ve got you.” He held a hand behind his back, pushing him upwards.
His Alpha stamina had allowed him to quickly recover after mating for so long, so he had almost forgotten it couldn’t have been the same for his Omega. Monoma was strong, but in his state his natural muscles were no use with pheromones weakening him.
Once he managed to sit up, Hitoshi went back to dressing himself. Neito had already licked up all his cum which left him mostly clean, he would still have to bathe later that night. He pulled on his boxers and pants before shrugging on his shirt.
He directed his attention back to his Omega, quickly moving back to his side to dress him. He helped him with his shirt and pants, watching as he slowly regained his energy. They quietly chatted about their weekend plans while Shinso fastened his belt.
After another minute of rest he managed to persuade Monoma into standing up, which then evolved into them walking out of the room and into the silent hallway. Almost everyone in his class was asleep besides them, so they managed to get by with nobody noticing them. Not to mention the pungent smell of their scents following them.
They moved into the elevator and Shinso pressed the button for the lobby. Before the elevator door could close, Kendo walked out of her own dorm room and joined them in the elevator.
Hitoshi froze at the sight of her but tried to keep his cool, Neito, on the other hand, seemed far too tired and dazed to care about her joining them. It was one thing that their clothes were rumpled and probably stained with cum, but it was another thing that Neito smelled so heavily like Hitoshi’s scent it was blinding.
She joined them quietly and waited as the elevator went down. It was the most embarrassing twenty seconds of the Alpha’s life. Their relationship was so obvious in that very moment anyone could’ve picked up on it. Yet a part of him relished the fact that she knew Monoma was his.
The elevator opened with a ding and she was quick to leave them. He looked over at Monoma who must have regained his grip on reality because he wore a pained expression. It couldn’t have been easy for one of his best friends to walk in on them like that.
They awkwardly walked into the common room.
Momoma grabbed his arm. “…Thanks for today, it was nice.” He admitted.
“Of course, how much longer do you think you’ll be…?”
“In heat?” He finished it for him.
“Yeah,” he admitted awkwardly.
“It’s been going on for at least two days, so it’ll probably go through to the weekend.” He explained and couldn’t help but look away.
Shinso thought for a moment but decided to go for it. “Could I… come over?”
“Oh, uhm, I’ll see, my parents might go crazy over the mark, though.”
He suddenly felt guilty. “I get it, just let me know if things get bad, okay?” He said, remembering the scene he walked in on early that day, of Neito curled in on himself masturbating.
“Will do, just text me, yeah?”
“Yeah, of course.”
Words were left unsaid in the air during their goodbye. Too much had happened in the past six hours. Shinso couldn’t swallow all the emotions he was feeling in the moment, but he hoped that the next time he saw his Omega, he would be able to express his feelings more properly.
Slowly, he turned towards the door and started to walk away, leaving Monoma alone in the common room. While reaching for the door he had to look back, savoring his scent and those soft blue eyes staring back at him.
“I love you, by the way,” he said in the doorway.
”I know,” Neito replied and Hitoshi smiled because he knew that was the blond’s stubborn way of saying it back.
