Izuku couldn’t place his finger on it, but, but something isn’t right. The hybrid lifts his bag up and checks it making sure he left nothing behind in the car or worse, the store. He pats himself down, he has his phone, though it’s dead. He has his keys and he’s pretty sure he could just borrow Katsuki’s charger if he couldn’t find his own.
He’s got his wallet, what’s wrong? What’s giving him this dreadful feeling of anxiety? Did he not have a good day? Maybe he’s overwhelmed!
Truly, he hates feeling like this. Having this unsettling weight on his chest, and as a rabbit hybrid, this nervousness was considered the ‘norm’ and was often overlooked. Nothing provided to give him ease, besides a few videos on the web about how to attempt to relax, little exercises, breathing techniques and games he could do to help with the all natural anxiety for a prey hybrid like himself.
Izuku figures he’d just have to wait it out, he hopes he doesn’t snap on Katsuki out of irritation. Lately his alpha has been a bit out of sorts , Katsuki often complains that he’s bitchy and needs to get his ahem ‘ knot wet’ or do something because he’s incredibly pent up.
Izuku slouches and sighs, keys in his hand as he unlocks his door. The minute he steps into the house, there’s a shiver that runs up his body and the most delicious scent to ever cross his nose.
Izuku steps in, shaking his head to try to clear his temporary mental fog. Saliva pools in his mouth when he closes the door.
“ Kacchan! Are you home?” He asks, toeing his shoes off at the door, tail wagging gently. He walks across the living room expecting Katsuki to come stomping out of the kitchen any moment now.
He heads straight for his own room, when he hears a very loud and intimidating growl.
“ EEPK !!” Izuku squeaks embarrassingly loud, ears up right and every hair on his body standing tall. He shoves his room door open glaring at the wolf huddle in his bedroom.
“Kacchan! October is long over, that's not nice!!” He snaps, then he realizes and tenses, this is his room right? Izuku looks back across the hall at what’s definitely Katsuki’s room, before looking back into his own, eyes locking on large dark pupils.
“W-huh?” Why is Kacchan in his bed?!!
“The fuck are you doing here shitnerd?!!” The wolf hybrid snaps enlarged fangs hanging over his lips, ears flattened against his head.
“Wha- Kacchan I live here too!!”
“No! You dumbfuck didn’t you read my me-me-“ the blonde curls over whimpering lowly, face buried in Izuku’s sheets. Now that Izuku takes a really good look, Katsuki’s skin is flushed, he’s red all over and covered in sweat, and has no scent patches to be found and- and…
Izuku belatedly realizes that the most delicious scent he’s been smelling since he walked into the house is Kacchan, that scent is so strong it’s giving him brain fog every five seconds. Izuku’s gums are starting to itch.
“Wait! Kacchan are you in heat?!” Izuku moves to step forward and Katsuki sits straight up with a snarl, loud and shaking, it sends fear straight down Izuku’s spine. He tenses and stands in place a bit confused.
“Don’t fucking move Deku!” Katsuki yells at him. He looks adorable, in one of Izuku’s shirts, in Izuku’s bed. If Izuku could think, he’d wonder if this is why everything in the house was washed and clean whenever he came back after Katsuki’s heat.
Did he always get in Izuku’s bed?
“But Ka-“
“I’m serious!! If you move I’m going to fucking chase you!!” Katsuki pants, hunched over the bed, squirming around on the sheets, trying to get through this wave of pain without doing anything creepier than being caught in Izuku’s bed.
“ I’m- I’m not that far along but, with an alpha here it’s different!”
“Th-then what do I do Kacchan?! I can’t stand still the whole time!!” Izuku panics, his ears drooping over the side of his head. He nibbles on his bottom lip wondering if he could outrun Katsuki with his quirk.
“ I don’t know!!! Just don’t move!! F-fuck! Didn’t you get my message?!” The blonde whines clutching at a pillow, he wants to chuck it at Izuku’s head so badly.
“No?! My phone is dead!!”
“Damnit Deku!! Just Get the fuck outta my sight!”
“ and don’t let me catch you…. don wanna hurt alpha..” the omega murmurs, Izuku’s ears twitch when he hears how concerned the hybrid sounds or the fact that Katsuki has referred to him as alpha? Like, as in his alpha?
No, Izuku really shouldn’t be thinking about that! This situation is quite dangerous for him, heat/rut sharing without preparation or knowing the limits of each other is a large issue.
Izuku’s stares at Katsuki, unaware that his own eyes have become slitted, his fangs hanging over his bottom lip as he shifts into a fight or flight stance, ready to bounce off any minute.
They stare at each other for a bit just waiting for one to make a move and in a blink of an eye Izuku is flinging himself outside his room door with Katsuki hot on his tail.
________
Damn, the front door is locked. If Izuku breaks it down to escape he’d be putting both Katsuki and many others at risk! His eyes darted around the apartment looking for ways he could shake Katsuki, his heart’s pounding in his chest, anxiety bubbling up. What would happen if Katsuki caught him?
Wasn’t it usually the alpha to chase the omega?
But wolf hybrids were different. Izuku’s read about this, but he’s so frantic he can’t think about what it is that happens after he’s caught.
He could keep running around their apartment until Katsuki gets tired. Izuku did have plenty and more stamina. But it’s becoming increasingly hard to dodge everything, he’s in a closed space,their shared furniture is everywhere, picture frames, flower vases, all might merchandise.
Luck is not on his side! On one hand Katsuki might kill him if he catches him, on the other, Katsuki WILL kill him if he puts a hole in the wall! He’s putting in so much effort to move fast and flawlessly!
Even with all his stamina,and training, he’s still a clumsy dumb rabbit. Hopping around their house without any shoes on or protective gear! Izuku steps onto the cord of their unplugged heater and screeches when his toes curl around the plug sitting near the wall innocently. Pain shoots through his body and he stumbles forward, face first into the wall.
“Gah- Ack!”
Katsuki’s far gone, too far gone to know Izuku had hurt and injured himself. When the blond pounces on the groaning figure below.
