Chapter Text
shouta was huffy.
it wasn’t his fault! his heat hit him out of nowhere and his mate had all but squirreled him away into the teacher’s dorms before he could ‘commit crimes’. whatever that meant.
the thing was- his heat caught them unprepared and he hadn’t stock up on his beloved jelly packets before he was caught prisoner. he just knew that he had at least half a carton left in the 1-A dorm’s kitchen. hizashi had specifically forbade him from stepping a foot out the door- which- not a problem, he’ll just use the window.
hizashi had gone to inform nedzu about the situation and the kids should still be in class. he would just swing down, steal away his jelly packets and no one would be non the wiser. literally in and out. easy.
what he didn’t account for was the possibility of someone to not be in class. his heat has swiftly and effectively rendered his memory and attention span regarding anything that wasn’t instinct driven utterly useless. unfortunately, that included the known fact that a certain green-haired problem child had been out of commission the past two days, banned to the dorms until his fever ran its course.
so, of course, with his dumb luck, running into the child was basically inevitable.
shouta froze as he came face to face to a startled teary eyed midoriya staring right back at him with wide green eyes. the boy looked to have stopped dead in his tracks into the kitchen. midoriya must have smelled the scent of his heat, of the barely restrained omega because he watched the kid’s nose twitch as he took a hesitant step forward, chirping a tentative pack? parent?
that singular noise triggered every instinct in his body until every part of him was practically screaming puppy puppy puppy puppy.
and really, it was hizashi’s fault for leaving him alone in the first place. shouta refused to be held accountable for the sequence of events. he tried to reel in his omega. really. you have to believe him.
yet, even with all of the self control he could muster (which wasn’t very much), shouta couldn’t help but open his mouth and chuff a distinct call of puppy, come here.
he watched the puppy perk up, big green eyes widening before he was all but scrambling across the room and into shouta’s waiting arms, chirping happy, relieved, thank you mama.
at once, all of shouta’s previous hang ups, every single one, vanished into thin air, replaced by a visceral wave of parental pride and joy. he didn’t even have it in him to be sorry. he couldn’t even remember what exactly he had to regret. it didn’t matter now.
his omega was yipping in unabashed joy. he was now a mama to a pup and his first order of business was to take his baby back to his nest so he could fuss and fret and drown the puppy in his scent until everyone knew he was his.
after he stole back his jelly pouches, of course. he gave the puppy a pouch for helping.
_(:3 」∠)_
when hizashi stepped into the apartment not to find his mate restlessly pacing the hallway, he was admittedly concerned. happy his omega wasn’t fretting, sure, but concerned all the same.
he followed his nose to their bedroom, shrugging of his jacket as he walked pass the couch. a whiff of a foreign scent that clearly did not belong to his mate tickled his senses, yet it was strangely familiar.
“shouta,” he hissed at the sight that greeted him.
shouta rumbled lazily in greeting from where he was curled in the mess of pillows, blankets and various random articles of clothing from their pack members. a very normal sight for his mate in heat.
what was not normal was the presence of a second smaller body sprawled over his mate, scent content and pleased as shouta’s hand pet over fluffy green curls. hizashi was used to shouta constantly trying to steal away his students during his heats but he had never successfully gotten as far as having them in his nest. actually- was that-
“midoriya?” hizashi watched the boy perk up at his voice, sitting up to scent the air.
alpha? pack alpha? izuku chittered curiously, peering up from the cocoon of blankets shouta had bundled him in. he took in the scent of the newcomer, before turning to shouta to chirp questioningly mama’s alpha?
apparently, no one cared for the rhetorical cliff hizashi was just forced off of because he was not given any time to process the situation and formulate an appropriate reply before his mate was happily crooning affirmatively in response to the pup’s question. instantly, a burst of excited pheromones flared from the puppy, who scrambled to free himself from tangled blankets and rush over to stand before him, staring up at hizashi with huge emerald eyes practically sparkling with so much hope that hizashi was taken aback. he barely heard the amused huff from shouta.
papa?
the blonde man felt himself freeze before he was sputtering to reply. his obvious overwhelming panic and the lack of immediate positive response had the puppy flinching and a spark of guilt flared in his chest
“i- uh. i’m sure you already… have…?” he trailed of to shoot his mate who was already glaring at him a confused, questioning glance.
no pack. puppy no pack. shouta whuffed chidingly, fretting over his puppy’s growing distress, flaring his own scent of comfort. hizashi’s eyes widened in realization, gaze snapping back over to his student who was fidgeting uncomfortably like he was trying to shrink himself under their gaze. izuku hesitantly peeked up through his messy bangs pitifully to chirp quietly.
not papa…? the pup asked meekly, scent already sad and mournful. hizashi looked between his mate who looked like he was trying to set him on fire with his mind and sad little puppy before realizing this was just a fight he wasn’t going to win.
sighing in defeat, hizashi lifts a hand to pet through fluffy green curls, startling big green eyes to look up at him. he offered the boy a fond, apologetic smile before crooning lowly. papa’s sorry, puppy.
he watched the pup blink up at him before he broke into a impossibly bright, beaming smile, surging forward to snuggle into hizashi’s front, happily wiggling out a gleeful scent of thank you papa. my papa.
hizashi felt his heart stuttered in his chest and looked up to see his mate watching them with an expression of smug satisfaction. he didn’t even have it in him to be annoyed as he gathered the puppy into his arms when the little thing started purring.
how in the world was he supposed to resist?
he still disapproved of his husband’s bad habit of kidnapping kids and attempts of hiding them away in his nest during his heats. though his victims were rarely discontented- the 1-A kids couldn’t make their satisfaction of their dam claiming them as his own when he was stripped down to his absolute base instincts more obvious with all their purring and snuggling- it wasn't right nonetheless.
but looking down at the obviously touch starved puppy in his arms, scent sweet and happy, he could make an exception just this once.
(it will not be just this once.)
(shouta knows.)
(it would be his fault anyways.)
