Miruko in Heat [MHA]

Credit: MightyMoosifer

===================================

Mirko hated being in heat; it made trying to go about everyday life worse than usual, seeing as she was needing to take breaks every few hours to keep herself from literally exploding in some sort of lust-fueled fugue. She had talked to some of the other female heroes, asking if they had felt such insane lust and madness, and none of them had the same experience; not even Tsuyu, who was literally part frog. Nevertheless, she took it in stride, doing her best to keep herself from going insane day in and day out for one week per months. Many of the heroes wondered where she disappeared to during those times, but no one knew for sure … well, no-one but her closest friends who she recruited to help her through it.

Being in heat did terrible things to Mirko, things she would rather the boys at the academy not hear about. Regularly, she was a Goddess among them: fit, tall, with rippling lean muscles, fat F-cup tits, a fat ass which jiggled, and powerful thighs she could crush someone's head in between with enough force. What completed the package was the red eyes, huge bunny ears, and the long white hair which reached well past her ass. But being in heat made her even crazier. Her hips and tits filled out, her ass growing massive and her breasts reaching H-cup size. Her pussy puffed up, forcing itself open as juices flowed out of it like a river, and her libido slammed into the roof, making her get turned on the by slightest thing.

Regularly, Mirko would wear pajamas to bed, getting up in the morning, looking out her apartment window and down into the city; not when she was in heat. She would wear nothing, lest the slightest crazing of fabric over her tight cunt and protruding nipples made her yearn to cum. In the morning, she would open her drawer and pull out her many toys, stimulating herself and forcing an orgasm, giving her a few hours of leeway to get ready and perhaps trying and get something done. But, as always, it failed; the hot water in the shower would send her into a frenzy, the slightest image of a woman's cleavage or a man made her pussy explode with delight, and smelling the scent of another human made her strip off all her clothes and beg to fuck. She was thankful that Nejire would stop by to help her out and keep her secret; then again, she was also thankful that Nejire was so skillful with her tongue, making her cum in seconds flat rather than minutes or even hours using her toys and wands and vibrators.

Still, being in heat only made her want cock even more, and rubber toys and tongues and fingers could only do so much. The more times she was in heat and avoided cock, the crazier she became next time, and it had been many, many times that she had been in heat. Recently, she had taken to researching the men at the academy, hoping to see one which might send her lust into overdrive and make her actually consider carrying their babies in her belly. She enjoyed the brawny power of All Might and the fat cock he might have between his legs, even in his not super-powered form, or perhaps even Endeavour and his reportedly elephantine cock. But then an idea struck her whilst she was sitting on her chair, legs up on the table as she fingered herself: these two men had monster cocks, but what might their protégé be holding back?

Izuku was pretty normal, for a super hero; he seemed nice enough, looked young, was unassuming, short, and kind. But For some reason, his attitude, his little quirks … they drove Mirko crazy. She wanted to see what he was hiding, wanted to know if he really had a monster cock in those baggy pants of his, wanted to feel his cock and cum in her, giving her a litter of children to grow in her belly and make her forever horny and her tits fully of milk. She looked at a picture of him, and the instant she did, her legs seized, her body began to vibrate, and her cunt splashed juice everywhere.

She began to browse more pictures of him, and her eyes went wide, her jaw slacking as she began to drool over every picture that crossed her eyes. His tight suit failed to hide the impressive bulge which ran down his left leg, reaching his knee, the latex of his pants wrapping around each and every crevice his cock had, showing the veiny shaft, the fat balls, the thick head which was larger than her mouth, everything about this surprisingly large and yet still soft cock making her cum again and again, the image burnt into her brain as she screamed in her little apartment, covering her computer keyboard and her floor in her sweet-smelling rabbit juices.

She knew exactly what she would do with him: she would make him into the perfect sex toy. Surely a man with a cock like his would have had his way with any woman who crossed his path, fucking and destroying cunts wherever he went. She had very particular tastes, but if he was willing, she could take him, mold him, and transform this Izuku into the perfect little sex toy, the man she could call on to fuck her whenever she was in heat, to satisfy her, and perhaps breed her as well. Perhaps that was the heat talking, or maybe her ferocious appetite for that massive cock, but just looking at it, imagining what kind of children it could put in her, imagining how fat her belly would grow if he emptied his massive balls inside her …

Mirko had to go back to fucking herself, shoving a line of anal beads into her asshole whilst she stuffed two vibrators into her puffed up, enlarged pussy. She slowly began to pull the anal beads out, the vibrating plastic parts shoved all the way to her cervix, shaking her body as her cum-slick thighs shook and tightened, her knees banging into each other while she forced her tight asshole to quiver and stretch as each bead came out, tightening her pussy around the vibrators. She screamed once more, her pussy beginning to grow weak and tired after spewing so much cum from deep inside her everywhere. She needed some sleep; she needed some time away from looking at the massive cock her new sex toy had. She left the computer running, pulled out her anal beads and vibrators, and slipped into bed, pleasuring her puffy nipples until exhaustion overtook her and she drifted to sleep …

#

The following day, Mirko set out to find her little toy.

She got out of bed, biting her lip as she felt the cool air from the air conditioner brushing over her ultra-sensitive nipples and pussy lips, keeping herself sane by saving her sexual energy for the man she lusted for. She lipped on a pair of short shorts which acted more as a skirt, pulled over hips enough to hide her pussy from immediate view, but if she spread her legs too much, it would be quite easy to spot. She didn't wear panties, lest the rubbing fabric turn her on and make her cum while she walked. Her huge nipples were hidden beneath a loose sky-blue top which only tied at the top near the neck, flowing down over her tits, her thumb-sized nipples pushing through and her dinner-plate areolas unable to be hidden by the shirt. All dressed, Mirko slid a finger up her skirt and fingered herself to orgasm, hoping it would help her get through the few minutes it took to get to the academy and meet this new hero.

The train ride there was difficult. Men and women kept staring at her, and it didn't help that her nipples were beginning to leak, staining her blue top even darker, her pussy juices flowing down her thighs as she struggled not to play with her enlarged clit. Finally reaching the academy, she ran out of the train, pushing herself towards the building, hyperventilating as she felt the yearning need to cum, to play with herself, to get fucked …

Thank God the blue-haired Nejire spotted her and ran up, leaving a few other friends, looking absolutely panic-stricken.

"Mirko, what in the hell are you doing here?" She asked in a harsh whisper, looking around, seeing everyone outside the academy staring at them, and more specifically the bunny girl. "You're in heat! You should be at home until all this blows over!"

"I need to find … a new hero. A man. Izuku." She said, drooling after speaking his name, more cum pouring down her leg, the scent of men and women, the smell of her own cum turning her on. "Find him for me … I need him. Need. Him."

"I … Mirko, I don't think this is a good idea …"

"Fuck good ideas, I need to cum now! She me where he is!"

Nejire, unable to say no to her friend, beckoned her into the academy, dragging her through the halls and into a nearby empty classroom while she went to her homeroom class to get Izuku. She stepped in and asked for Izuku to come out and meet her friend, which the young, naïve boy was far too happy to do. He wore a regular shirt with a tie and pants, but underneath, even Nejire could sense the monster cock which he tried to keep contained. She brought him to the empty classroom, sending him in before closing the door and standing guard.

Inside, Mirko was practically naked, slipping off her pants and already having thrown her top off. Izuku looked stunned, quite unsure as to what he should do as the bunny-eared woman descended and grabbed him, shoving him to a wall as she began to undo his belt.

"Well, h-hi there." He said, grinning awkwardly. "Maybe we can like … exchange names and stuff before we jump to this?"

"No. Need cock, need your cock now!"

"A-are you sure? It's pretty big, most girl's I've been with can't handle it."

"Oh, I can handle it, stud. Just show it to me, let me at it and I'll –"

Mirko gasped as his belt came undone, his pants hit the floor, and his cock sprung out of its containment. Mirko gasped as the monstrous sausage slapped her in the face, blood rushing to it as it inflated and hung above her, looming over her like some sort of alien monolith. She began to drool, her jaw hanging down as she frothed at the mouth, wanting nothing more than this monstrous slab of meat. It was huge! A while 18 inches long, and a third of that wide, so large that no human woman could possibly take such a magnificent cock … no one but her. His balls were each as large as a basketball, compressed inside his pants and beginning to inflate the moment they were released from their containment. She loved how each was as large as her head … and filled with delicious cum …

"S-so you see, it's a bit … freakishly big …" Izuku said while gulping. "I hope you don't run away or find me weird, I just … I really want a girl who can handle it, a girl who can –"

Izuku didn't finish as Mirko grabbed his balls, stuffing her face between them, motorboating his testicles like he might motorboat her tits. He gasped, groaning as he felt blood rush to his cock thickening it and shooting it to its maximum length of twenty inches long! He could feel her soft fingers and manicured nails rubbing his monstrously sensitive balls and his hyper cock, stroking it and feeling how thick and hot and meaty it was.

She pulled back from his balls, pushing him down into a chair as she wrapped her massively engorged tits around it, spilling milk from her nipples onto his lap, using the white fluid as a natural lubricant for the tit job. Izuku looked shocked, watching her as she was entranced by his cock, stroking it, coating it in a thin layer of tit milk as her lips expanded to wrap around the entire head. The monstrous cock was almost as girthy as her head, and seeing her extend her jaw to encompass the entire tip was something which drove Izuku over the edge. He moaned and groaned, feeling his cock being milked by both lips and tits, unable to get away, and unwilling to get up. He wasn't sure if this girl he had never met before would be able to handle his cock, but seeing as she was quite adamant about sucking it and stroking it, he was willing to give her the benefit of the doubt as to if she could take it.

Mirko pushed herself further, swallowing more of the cock as her throat stretched to thrice its previous width, feeling it reach her stomach and actually fuck her intestines! She moaned, feeling how it stretched out her neck, her sternum, her stomach, feeling it between her tits and inside her … she was in heaven. Her legs shook as she came, covering the floor in her juices, milk still pouring from her enlarged mammaries as Izuku watched, horrified and turned on, shocked that such a woman could swallow his cock in almost its entirety! He was certain, then and there, that this was the woman he was meant to fuck, the woman of his dreams, which would make every fantasy he had ever had come true.

"Sorry, w-what's your name, honey?" Izuku asked, his eyes fluttering and his mouth open, drooling in ecstasy.

Mirko pulled herself back, seeing the cock emerge, coated in a thick laying of saliva as she wiped her mouth and giggled. "Mirko, darling. I'm Mirko. And I'm about to make your dreams come true."

"Oh, g-good to hear …"

She stood and crawled atop him, sliding her puffy cunt over his cock, stimulating it as the massively thick lips pulled back, revealing her engorged clit which was as long as one of her fingers, and her swollen lips which looked like a puffy asshole, begging to suck down something. Izuku smiled nervously, watching as she eased herself onto the cock, feeling her hip bones actually grow achy from being stretched by just the head of this python. She released the tension in her shaking legs, letting gravity do the work as she was yanked down, slamming the cock through her body, her cervix weakening and allowing it to pierce her womb and then some. She looked at her belly, her abdominal muscles fucked up as the cock literally pushed itself through her skin, pressing itself between her tits, wrapped in her belly flesh. She giggled, moaned, her brain about to break fro the pain, pleasure, and absolute ecstasy of finally letting her heat get the best of her, her libido taking over as she satisfied her most primal of urges: to breed.

Izuku was screaming in joy, grabbing Mirko's fat tits and massaging them, seeing his fingers sink into her soft fluffy pillow tits, burying his face in the milky udders. His lips latched onto one of the mammaries, sucking the milk out of it as he began to thrust upwards, one of his hands grabbing his cock through her skin. At the same time, Mirko grabbed her tits and squeezed them together, stuffing Izuku's mouth full of milk whilst both his hand and her tits smothered his cock, which was already firmly shoved so deep in her womb it would be a wonder to see it ever come out.

"Izuku pulled back, looking at her as she leaned down, kissing him, shoving her tongue into her mouth and swirling it around. She sucked on his tongue, kissing him, making him feel molested as she did as she wished with his mouth, but let his cock ravage her. He didn't even need to thrust for her to have orgasm after orgasm, her cunt going haywire as pussy juices leaked down across his monstrous balls, her thick muscular thighs, her toes dripping with liquid joy. He was nowhere near close to releasing his own load, and Mirko could tell. She put her feet on his knees, grabbing his shoulders as she began to pull herself off his cock, screaming the entire time, feeling every single vein, every crevice of his cock pulling against the ribbed insides of her cunt.

She could only bounce on his cock, swallowing and spitting out the same ten inches, unable to swallow the rest lest she get trapped again. As she did this, her pussy lips closed in on his head, rubbing the sensitive but under his urethra, stimulating him as both of them felt his cock fill up more, expanding and thickening, making her cunt stretch out even further. Izuku reached up and grabbed her tits again, squeezing them as milk poured over his hands and down his arms, covering him in his goo and hers, pre-cum and pussy juice slapping and flying everywhere, making them little more than moist balls of goo fucking each other. Izuku didn't mind … he licked his arm, enjoying the taste of her cum and milk, feeling it make him go haywire, the powerful aphrodisiac making him thrust a bit more, a bit too much …

Izuku squeezed her nipples and yanked Mirko down, forcing her to slam and take his entire cock again, making not only her cum, but him too. He screamed as he buried his face in her tits, feeling his cock pump and pump, gallon after gallon of liquid cum pushing its way into her belly, forcing it to expand, her abdominal muscles disappearing as her stomach began to extend, looking more and more pregnant with each drop which poured out of his tip and was trapped by her deep hole. She rubbed her belly, moaning as she felt billons upon trillions of sperm assaulting her eggs, fertilizing her, making her feel … fulfilled. She was a mother, she was impregnated, by this powerful cock and the virile cum which spewed from it. She felt caught in ecstasy as she came over and over, her cunt sucking on the cock which kept on giving more and more. As she looked more and more pregnant, eventually her puffy lips couldn't contain this much cum, and released their grip on his cock, a waterfall of white semen pouring out and covering her legs and his, the floor stretching out into a pool of seed which made the room smell so, so, so good to her.

"FUUUUCK!" Mirko screamed, grabbing her tits and spraying milk everywhere. "GIVE ME YOUR BABIES, IZUKU, GIVE ME YOUR BABIES! YES, Yes … yes …"

Her eyes fluttered, her sexual stamina finally quenched, the need to breed finally defeating her as she went limp, semi-unconscious as she slipped off his cock and onto the floor. Izuku stood, weak at the knees but stull shockingly hard, the aphrodisiacal milk keeping him erect, as Mirko's body wanted her to breed, and would keep any man who feasted on her juices hard enough until she was impregnated. She writhed in the pool of cum on the ground, smiling, her limbs twitching as her brain tried to process the joy she had just felt. She turned around, moaning, on her hands and knees, sucking on the goo, wanting to taste it as well as feel it inside her.

Looking down at her wretched and pathetic form, Izuku got an idea. Not a good idea, but an idea, a lustful need to fulfill a fantasy he had had for many years. No woman could take his cock in their mouths, let alone their wombs, and yet here was this rabbit girl who had done both of those, with shocking efficiency. Watching her writhe in his sea of cum, he got on his knees, touching her body, spreading her ass cheeks to see the gushing pussy lips from which his seed continued to pour out, and looked up, to the perfect, pristine, never-before-stretched asshole. He sucked on his finger, moistening it up as he pushed it into her asshole, not hearing her complain, but noting how difficult it was to get it in. He pulled his cock up, squeezing the tip as a monstrous glob of seed poured into her ass crack, his finger slipping into her asshole with ease now. She continued to not notice, still in her blissful fugue, and feeling bold, he got into a crouched position, lined up his cock, grabbed her hips, and shoved his cock inside her.

Her eyes snapped open as she realized what was happening, reaching back to feel Izuku's massive balls slapping against her thighs, screaming as she felt her body being ripped in half. She was unable to move, stuck in this position, her face pressed into the floor, constantly feeling cum splash into her open mouth, up her nose, invading her holes as she was fucked in her tiny little pristine ass. She wasn't sure how long she could go for, if she could take it; he was so big, so thick, so long, so powerful! Every stroke pushed his cock through her intestines and back into her stomach, invading the same organ from the opposite end, making her feel skewered. She reached with one hand onto her belly, feeling his cock rip through her body, moaning as she felt her insides being rearranged by his monster cock. She began to moan and scream again, the cum in her mouth gurgling as she felt another orgasm approach, spraying her own cum and Izuku's out of her cunt and all across the floor.

Izuku continued ramming into her ass, his good-boy demeanour stripping away as her went wild, fucking her perfect hole, losing track of time as the alarm for the next class rang, but he didn't care. Several women peeked inside the classroom they were supposed to be using, seeing his monstrous cock fucking the daylights out of Mirko, and decided to have class elsewhere, leaving them to their own devices for hours on end. Mirko, unable to move, unable to do anything but be used and fucked, lay there, gallons upon gallons of seed pushed into her asshole, into her pussy, so much cum it started to leak out of her nose and mouth as it filled her from the bottom up. She was in love, she was in paradise, and she knew that after this, there was no way Izuku would ever let her go.

#

It was nearing the end of the school day, and Izuku finally felt himself go soft, pulling his cock from her asshole as he pulled her onto his shoulder, feeling cum pour from both ends of her. As he walked through the academy out the front door, every woman that as there immediately felt the pangs of lust and orgasmic joy. Many felt their cunts explode and spray juice all over their pants and skirts, Tsuyu and Mina both falling to their knees and rubbing themselves, the sight of his cock too much for them to handle, and the pheromones coming off of the in-heat Mirko causing them to lose their minds. The bunny girl was like some sort of lust bomb: everywhere she went, women within a mile radius went into a sex-crazed heat, wanting to find and fuck the nearest cock. Izuku enjoyed watching this as he walked naked through the halls, some women even literally worshipping him as he passed by, no cock in the city – hell, even the world – coming close to his.

Mirko gurgled something while she rode on Izuku's shoulder. She was still unable to speak, barely conscious as she was carried from the school, into the city, into parts unknown, leaving a trail of hard cocks and gushing pussies wherever they went.

"Don't worry, Mirko … we'll get to know each other a lot better. All you have to do is take my cock in your holes, understood?" Izuku said.

"Yeth … yeth mathter …" She choked out, groaning as she finally slept, feeling his fingers violating her holes even as she drifted to euphoric sleep.

"Good girl … rest now … because when you wake up, you'll have to service me twenty-four/seven for the rest of your life …"

#

Several months alter, and Mirko's home had become Izuku's.

She had dropped out of the academy after becoming pregnant, as she was much too thick and curvy now to properly fight crime with a litter of bunnies in her belly. She had grown more milfy due to the pregnancy as well, her tits larger than any other human's, M-cups which only stayed on her chest because of her powerful back preventing them from snapping her in two. Her ass had grown massive and thick, and her pussy was permanently puffy as well. Her belly was huge, spilling out everywhere, each of her tits three times the size of her head, and her belly larger than both her tits put together, all nine of her children inside kicking and waiting to emerge.

Whenever Izuku came home from a day superhero-ing, she was happy to get on her knees and suck his cock, relieving his stress for the day by literally sucking it out of him. She was happy to please her master, blowing him and letting him fuck her face every day for as long as he wanted; sometimes she wouldn't even get dressed knowing that when he got home, he could very well just rip all her clothes off and ruin them. Afterwards, she happily made him dinner before sliding his cock into her asshole, using her back as a plate while he ate and got his cock milked by her sphincter, taking more and more cum in her with each passing day. She never needed to eat herself; with all the cum she gurgled and sucked down, she was quite full from a mere blowjob, sometimes even getting fucked anally was enough to fill her belly and keep her sated for an entire day.

After being fed, she sat on his lap with his cock in her ass, continually feeding her his protein-rich cum whilst he sucked the milk from her monstrous mammaries, using her like his own personal cow, the milk only making him hornier, harder, and causing him to produce more cum than ever before. She loved feeding this cycle, swallowing his cum and feeding him with her milk. She was in love, and she felt how he loved the babies in her belly, rubbing her swollen stomach whilst he was nursed by her milk. They often kissed, swapping the milk around their mouths, Mirko sucking down her own milk to make herself horny and happy.

"Master …" Mirko would start whilst he sucked on her nipples, feeling her tit run dry finally, "… I was wondering if you could help me with something, a problem I'm having."

"Oh?" He said, swapping nipples but still keeping his eyes on her.

"You see … I miss … I miss having some friends around. When you're here, I'm so happy and satisfied! I love when you're here! But I know you can't be, you have to leave and go places … and I can only satisfy myself for so long … I want other girls to play with, more girls to share you with."

"Oh? Are you saying I should bring in someone like … Tsuyu?" He grinned, his mouth covered and filled with milk. "I heard that frog girl can be quite stretchy."

"Oh yes, yes master! Fill her with seed and impregnate her too! Then she can come here and stay with us forever, she can never leave!"

"Are you sure that you can share me with another girl, darling?" He asked, massaging her belly whilst his cock released another torrent of cum. "After all, I know how jealous you used to get when you first got pregnant and Nejire would come over."

"No, master … please bring more women over, and breed them to. But … so long as I

'm your favourite. I have your favourite babies, and I have your favourite milk and holes …"

"Oh, darling, I would be happy to do that for you …" He giggled, pulling his cock out as it spilt cum onto the floor. "Go clean that up, and I'll go talk to Tsuyu tomorrow, and by talk, I mean I'll fuck her until she loves me. Then I'll bring her by and you can train her."

"Master!" Mirko screamed and hugged him, kissing him as she allowed him to empty another of her breasts. "Oh, I can't wait, I just can't wait, master!"

"But no matter who comes into this apartment, you'll always be my number one girl …" He winked, and Mirko fawned over him, moaning as that alone made her cum. "Now suck me off, slut."

"Yes, master …"

She giggled and got on her knees, sucking his cock again, feeling his half-flaccid cock rape her throat as she felt him dumping the rest of his cum inside her belly, making her feel sated, happy, and at home. She was so excited for the other girls; she could hardly wait. Soon the entire academy would be filled with pregnant women, all of them having been bred by Izuku and his monster cock. And who knows, perhaps he might have to use his superhero-ness to find more women and bring them by … Mirko wouldn't mind if all the women in the entire city were knocked up by him …

So long as she was his favourite.
