"are you okay? you look hot?"
"your forehead is on fire!"
"you look red. drink some water."
you've been hearing that non-stop all day. of course, you know that everyone has good intentions, but it was so annoying.
no, you didn't feel fine, nor did you feel sick. it was a strange, embarrassing thing to admit. in a world full of truly remarkable quirks, you just had to get a basic one. your quirk was rabbit. you know mirko? yeah, well you two are in the same boat.
you have floppy bunny ears the same color as your hair, a puff ball of a bunny tail, & muscular legs. all so cutesy & alright to deal with. the behavioral traits were what got you though. increased hearing, jittery/easily scared, & most annoying of all, the heat that came with it.
though it wasn't unusual to have heat, it was definitely not something you mention in a passing conversation. heat made it hard to focus on anything except for breeding & sex. your senses are enhanced, making clothes feel itchy at all times. your train of thought always derailed to live making. that's why you were prescribed heat repressant.
no side affects & it worked like a charm.
however, this month you forgot to stock up on them, & you just so happened to run out. you would've just skipped school to get some, but it was midterms, which comes with tests & presentations that simply could not be made up. it was either fail your classes or bite the bullet.
"oi! what's your deal?" someone barked at you. ah yes, your boyfriend of six months, katsuki bakugo.
"nothing," you said with annoyance. another thing about your heat is that you get irritable because of the overwhelming feeling of needing to do a certain activity. "don't worry about it."
taken aback, katsuki reached out for you & spun you around. your eyes welled with tears of frustration & utter embarrassment, the tips of your ears were red, & every thread of your clothes made your skin crawl. "hey, what's going on?"
"i-it's nothing, just leave me alone. class is about to start." you understood how much katsuki prides himself in his academics. you're not gonna be the one to drag him down; that's not very amazing-cool-awesome girlfriend of you, after all.
he wanted to say that he didn't care & let's just ditch class, but you both knew you couldn't. the exams were too important. luckily for the both of you, the last period of the day was study hall. most kids just skip it, starting their free time early.
just a few classes, then i can go get medication, that's not bad at all, i've been through worse, you thought in attempts to calm yourself.
yeah, but imagine how could it would feel to be absolutely railed, oh fuck, imagine katsuki-
you had to cut yourself off, he was standing right beside you after all.
your relationship with katsuki has been slow, healthy, & true. the most you two have done in the span of six months is make out, grind, & grope each other clothed. both of you saw a future together so having sex didn't have to happen right then & there. if it happens, it happens, but there was no need to have it to connect.
you didn't want you first time with the love of your life to be because of your current circumstances.
"did i do something?" he asked, making your ears twitch.
"no, it's not you," you reassured, "there's nothing going on." you both entered the classroom, & you could feel katsuki's worried stare focused on you the entire time.
you took exam after exam, which, in of itself, is a long, stressful process. the bell rang throughout the school, & your classmates shuffled out of the room to go to their last period. finally, it was study hall. you threw everything into your backpack without a care. you were practically panting.
throughout the school day, the pressure building inside of you only gotten worse. you couldn't stop thinking about katsuki. his god-sent body, his perfect face, his rugged voice. god, he turned you on so much-- too much, actually.
you felt bad for ignoring all of his texts throughout the day. if you didn't, however, you had a feeling you would've sent some embarrassing messages.
as you exited your class, someone grasped your wrist, dragging you out of the school. their touch lit you on fire. you knew exactly who it was. "let me go, katsuki."
"no, not until you tell me what i did!" he growled at you. he doesn't even realize how wet i am for him-
you had to shut off your thoughts, but that's easier said than done.
"i told you already. you didn't do anything."
"well something is going on with you. tell me what's happening," he raised his voice, a vice grip still hanging onto your wrist. you were getting overstimulated & overwhelmed. once again, you couldn't help the angry tears from forming. you couldn't help but hyperfixate on your panties brushing against your sensitive clit. you couldn't help that your nipples were painfully perked.
you can't just admit that though. it's such a stupid problem to you. you felt so wrong & disgusting for thinking about sex all day. "you wouldn't understand!" you finally yelled back. "you wouldn't get it."
he didn't respond. katsuki continued to drag you throughout campus, leaving you with your thoughts.
god, i made him mad, you mentally cried out. hopefully he'll hate fuck you then-
you want to rip out your own brain & throw it on the concrete. it was a constant cycle of that the entire walk.
a few moments later, you realized you were in his dorm, sitting on his bed with him across from you in his desk chair. both of your hands were in his as he brushed his thumbs against your knuckles. that alone gave you goosebumps. "please tell me what's wrong, baby," he said in a hushed near-whimper. "i'm worried about you."
"you really wouldn't get it, katsuki," you whispered, finally letting a few tears roll down your cheek.
he placed his index finger underneath your chin. he gently raised your head, your gaze following suit. the two of you locked eyes, his swirling with worry & yours sprawling in uncertainty. "then make me understand."
"it's my stupid quirk," you exasperated. you tried coming up with ways of how to say what you want to say without scaring him off.
"what about it?" he asked.
"you have such a nice quirk, you know," you started, avoiding his question. "it's just so much flashier & cooler than mine. there's already a rabbit hero!"
"what are you talking about? you do have a cool quirk."
"i'm a bunnygirl. nothing more. people already know what to expect-"
"what is this really about? you brag all the time how you get to come up with new ways to make your quirk yours," he countered, not convinced with your answer. "there's something more, isn't there?"
katsuki was so good at reading people-- at reading you. the other times you've confided in him, your voice lacked clarity, stability. why would it be different now? it wouldn't, that's why.
"yeah, there is," you admitted, tugging on his hands so he'd get closer. "i just don't know how you'll react or how to even say it-"
"it's fine. just tell me, i won't get mad or judge you or whatever," he assured. you began to cry even more, staining his dress shirt.
he smelt so good, i can feel his muscles through his shirt, he's so sexy-
"i need you," you muttered into his chest.
"what was that, baby?"
you glanced up at him, eyes glossy, lips pouted. "i need you."
katsuki's breath hitched, "what are you talking about?" yes, he's had theories about your quirk & its drawbacks. was this it? was his theory correct?
more tears of frustration rolled down your cheeks as you tried to explained, "i have... you know."
his cock stirred, scolding himself mentally for getting hard during a time like this. "have what?" he wanted you to say it, confirm his suspicions.
you took a deep breath. "i have this thing every month or so, & it just makes things so much harder."
"tell me." his stern voice sent shockwaves through you.
it made you obey him automatically, robotically. "i'm going through heat." a silence followed. "it's normal for people with quirks like mine to go through this. i usually have repressants! & i know this probably makes you so uncomfortable; i understand if you don't want to be-"
-- nsfw starts here --
katsuki cut off your rambling, almost offended. "don't ever say that. i want you, all of you."
"p-please don't say such things," you begged him as you felt your pussy throb. "i'm r-really trying to hold back-"
"let me take care of you, princess," katsuki purred, finger tips ghosting over your exposed thighs. he buried his face into the crook of your neck. "do you want this, y/n? because i want you right now. if you tell me you don't want this, i'll stop."
all you could do is nod, your breath turning uneven.
"say it, y/n."
"i need you so bad. please, katsuki," you cried out as you rubbed your legs together.
he smirked into your neck before he started kissing your neck. you couldn't help but whimper. he noticed you holding back, so he bit your neck. he sucked hickeys all over your neck. your unsteady breathes turned into needy moans.
"t-take off my shirt, please-"
katsuki took in your demand by ripping it off your skin as if it were poison. he unhooked your bra, throwing it on the floor. "ah fuck," he groaned, cupping your breasts.
"are they o-okay?"
"you're fuckin' perfect, baby."
with one, he replaced his rough, calloused hand with his mouth. you grinder against his thigh as flicked your nipple with his tongue. "k-katsuki~"
he switched to the other one, giving it the same treatment. "all mine," he growled in between. he nipped at the skin around your nipples. your neck & chest were soon littered with purple marks & bites.
"let me touch you," you begged & you began to fidget with the buttons of his shirt. "take this off~"
"so needy, aren't you, princess," katsuki teased, yet he gave into you. he threw off his shirt, looming over you. goosebumps pricked at your skin, all over your arms down to your legs. you found yourself trailing your hands all over his abs, his muscular arms, around his back. it was like your hands had a mind of their own.
you flipped the two of you around, so now he was under you. "c-can i please mark you?"
he let out a laugh of amusement, making your face turn a deep red. "you don't have to ask, baby," he told you. as a response, you mimicked his actions from earlier. your lips kissed all over his neck, leaving marks in its wake. you trailed down to his chest, then his abs then his v-line until you reached the band of his pants.
the entire time, he was groaning, feeding you praises that shot straight through your core. when you stopped, he looked down at you, & there you were, staring back at him with eager, wide eyes. he could read you so well. "go ahead, y/n. pull them down."
to which you did. you hands hooked both his uniform pants & his boxers. you pulled them down, & your mouth watered when his cock sprung out. "i-it's so big," you moaned; you meant to only think that, but you couldn't help it.
his mushroom tip beaded precum, his veiny shaft twitched in anticipation. "you see how hard i am for you? all for you," katsuki told you, watching your eyes dart to his then back down to his cock.
you started licking him to test the waters. you saw as his eyebrows furrowed together, his mouth agape, narrowed eyes. your licks evolved into you sticking his tip into your mouth. your tongue flicked around his cock. you crossed your eyes & whined when you tasted his precum. thanks to his quirk, it tasted almost sweet, salty, & god, was it addicting.
you bobbed your head up & down his thick rod. the tip hit the back of your throat while spit flooded your mouth. it was hard to breath, but you didn't care. having katsuki inside of you was more important than breathing. "slow down. you're gonna make me cum, good girl."
that was enough inspiration for you. you needed his cum. you forced your head all the way down his cock, your nose buried in his pubes. your eyes watered (for the fifth time today), & you stared into katsuki's eyes. both of his hands tangled themselves into your hair. "i'm gonna fuck that slutty, little throat, okay? just tap if it's too much," he informed, but he had a feeling you were going let him do whatever he wanted.
you moaned as a way to let him know that you heard him. the vibrations quivered his tip. "mmm, fuck. you're doing so good," he praised, jutting his hips forward the drawing them back.
his thrusts at first were small, in fear he was hurting you. however, as he looked down at you, your eyes rolled back, drool spilling out of your mouth, rubbing your aching clit for some sort of release, he couldn't hold back. he started using your throat as a fuck toy.
fast & rough, & all you could do was take it. take it, even though you're crying & it's hard to breath. "i'm close," he uttered out in between moans. his sultry voice turned a pitch higher in a humiliating tease, "you want my cum, baby? huh? c'mon, tell me you want it."
you choked out muffled, "yes please" & "cum down my throat please." he laughed at you trying to form sentences with your mouth stuffed. "such an eager bitch. fine, i'll give you what you want."
he thrusted his hips forwards, keeping your head in place. you face smushed against his hips. his cock twitched as he unloaded spurts of cum down your throat.
he pulled away, & strings of saliva mixed with his semen leaked onto your skirt. you looked back up at him, finding his cock still erect. "you look so surprised," katsuki said as he caught his breath. "i'm still so hard for you. after all, i told you i was going to take care of you."
"p-please have sex with me," you barely even whispered.
"what was that?"
"please-"
"i still can't hear you," katsuki told you, stroking his dick. he really knew how to push your buttons
"please fuck me, katsuki! i need it, i need you so bad~ i need your big cock inside of me," you blurted out. you finally let you stupid, nasty fantasies get the better of you.
judging from katsuki's smug expression, he wanted you to indulge in them. "alright, alright. you've been such a good girl for me. it's the least i could do," he shrugged before flipping you over so you were trapped under him. even in your most intimate moments, he was cocky. & god, did it make your pussy wet.
as he started to pull your skirt down, your hands shot to grab his wrists. "no, fuck me now, i can't wait. it hurts too bad," you whined, your glossy lips pouting.
"of course, princess," he said with a smirk. "whatever you want." katsuki's fingers dove under your skirt to push your panties out of the way. he held your legs up, placing your calves over his shoulders.
he lubed the tip of his dick with your juices by running it through your folds. "you're so wet for me, good girl."
"it's all for you, katsuki~" you purred, anticipation practically killing you. you felt pride as he turned his head to kiss the meat of your calf in approval.
"can't let it go to waste," he told you. he lined his thick, heavy cock with your entrance. something must've taken over you because, the moment it lined up with your hole, you shoved your hips forward with your entire body.
you let out a squeal of pleasure, your pussy stretching to accommodate for katsuki's lengthy cock. "shit, baby, you almost knocked me over," he chuckled as he readjusted. both of his hands were on your hips.
"shut up & fuck me," you growled at him. his cock twitched, brow raised in amusement.
"yes ma'am," he replied, "but remember you said that." from the get-go, his thrusts were powerful, immediately finding the cervix. your nails dug into his biceps down to his wrists. moans, whimpers, & screams spilled out of your lips.
katsuki took his fingers to your mouth & demanded in a low voice, "suck."
the action made you quiet down. he found your g-spot soon after, & you felt lightheaded. with his fingers down your throat, his cock abusing your most sensitive spot, & katsuki whispering dirty nothings into your ears, you shut your eyes & released all the tension building up.
"f-f-fuck, i-i'm cumming, katsuki," you rasped, voice having a small lisp thanks to his fingers. you squirted all over his abdomen, breath heavy & uneven.
he didn't stop though. he still rammed his big fuckin' dick in & out of you, not letting you calm down from your euphoric high. in fact, his hand that you slobbered all over found their way to your clit. he drew small circles around it. "ah, katsuki!" you moaned. "it's too much!"
"you'll be a good girl, & take it, won't you? i haven't cum inside you yet," he responded while his other hand pinched your nipples.
"i-i-i'll be a good girl, katsuki~" you slurred, speaking on beat with his thrusts. he made you cum three more times then you felt as his hips became more robotic, shorter, uncalculated.
"i'm cumming," he groaned through gritted teeth. "i'm cumming. fuckin' take all of it." thick jets of hot, white cum stained your walls. his dick pulsated inside of you. you came again; who could blame you?
he took a few deep breaths, collapsing on top of you as he pulled out of your pussy. cum spilled out of you & onto his sheets. he embraced you, whispering, "round two?"
