[Femdom, Breeding, Hyper Pregnancy/Cumflation]

The moon shone through the window as a young green-haired hero-in-training stepped into the abode of the woman he was interning with. Izuku Midoriya, Alias Deku, gulped a little as he felt the air within the apartment, especially how tense it was. He could practically cut through it with a knife and it'd still be as thick as ever.

"M-Miss Mirko? You called me all of a sudden, and you didn't even tell me anything except to stop by... A-Are you okay?" The young man asked aloud as he closed the door behind him, a few drops of sweat ran down his brow as he looked around in the seemingly empty living room. Working with other Pro Heroes was one thing, but having to deal with the biggest female hero in the business... It was a little intimidating, to say the least. Especially considering the puberty that he was going through.

He continued to take slow and deliberate steps around the apartment, checking every single room to ensure that nothing was out of the ordinary, while also trying to locate the woman that he had interned under. There wasn't anybody in the kitchen, nor on the toilet or in one of the spare rooms that had dotted the hallways. It was a rather spacious apartment, which just made him a little more suspicious.

Finally, when he checked the bedroom, he was in for quite a surprise. Laying with her legs spread out on the bed was the tanned beauty he was looking for, only with her legs spread to let him see just how inappropriately dressed she was. Her leotard, the one that she commonly wore whenever she was out doing her various heroic duties, was digging into her crotch leaving little to the imagination as her lower lips quivered...

"Took you long enough, kiddo..." Mirko, Alias Rumi Usagiyama, panted a little as she closed her legs before beckoning the young boy to come closer. "Now come on, what are you waiting for? Are you going to leave a woman while she's all hot and bothered? You're not the kind of hero to deny somebody a little request, are ya?"

Just the sight of the brown and toned woman made the young hero-to-be grow incredibly flustered, his feet instinctively backing away. "H-Hold on a second, I'm not ready for thi-" Izuku tried to protest, only to find himself suddenly pounced upon at breakneck speeds. Seconds later, his back met the floor as he had been mounted by the horny bunny, a soft giggle slipping from her throat.

Rumi licked her lips as she wrapped her legs around the young man while reaching one of her hands down into his pants. "Come on, I was trying to be nice and see if you were going to take the bait, but I guess you're a little too wet behind the ears. That's alright, just means I'll have to break you in the old fashioned way." The white-haired bunny chuckled as she pressed her near-exposed slit up against the young man's face, forcing him to get a strong whiff of her natural feminine musk.

The poor boy squirmed and struggled against her leg-hold, but he was no match against the strength in her thighs. She was one of the top heroes after all, so naturally, every part of her had to be in that very same top condition. The more he felt his breath leaving him, the tighter his pants grew, even as his nose pushed right up against her nearly exposed clit, prompting him to huff and gasp as he inhaled more and more of that sweet scent...

While her little target was too busy taking a deep breath of her wonderful musk, the Rabbit Hero was equally busy playing with the piece of meat that was growing steadily within his pants. Inch after inch. The more turned on he got, the quicker he grew. From a soft three inches, all the way to a foot as he steadily climbed the ladder of arousal. Something that enticed the brown beauty more and more.

"Sheesh, you're even bigger than most of the pros in their prime, you know? Maybe calling my cute little intern to deal with my full moon issues wasn't a bad idea after all." Rumi chimed as she momentarily released her grip on the boy, only to whip around and clamp her legs back down on him, as she now faced his cock while her ass pushed up against his face. Despite the moment of weakness, he was still left just as incapable of defending himself as before.

Her warm buttcheeks pushed up against his cheeks, slathering his face in her dripping juices as the bunny bobbed up and down, kissing his growing bulge as the seconds ticked by. The more she teased it, the closer it came to breaking free from its fabric prison. Her lips kept delivering kiss after kiss, until...

The older woman planted one too many kisses, as the boy cried out in pleasure as his pants popped open to reveal the juicy rod within. A veritable feast of meat and cum, packed in one perfect-sized package. Exactly what the bunny-eared woman had been waiting for.

"You can hold on back there, can't you, Izuku? Don't bother answering, because I'm going to dig in!" She was as fast as ever, even in sexual situations. Her lips wrapped around that mighty piece of cock before she bobbed up and down with the intensity of a jackhammer. Normally, it'd be her partners pulverizing her pelvis, but this time she had all the time in the world to make a meal and a toy out of her intern. Something that he was unfortunately forced to endure, as he could feel the warmth and the heat radiating off her nethers.

As he thought back, he did remember that she was a little squirmy around the day that he joined her agency. It had just been a full moon, and she was always a little too jittery, but she seemed to recover her spunky and tomboyish energy not long after that, so he didn't pay any mind to it. Maybe he should've, as he saw the full moon pouring in from the outside. He had heard about lunacy causing issues, but the moon inducing lust like this was completely new to him...

Izuku's eyes suddenly shot open as he felt a powerful pulse of pleasure shoot through his spine, as his temporary teacher squeezed her hand around his potent nuts. One squeeze was all it took for him to arch backward as he instinctively pumped his hips forward, pushing as much of that massive cock down Mirko's throat before blowing his load. Neither of them could even get close to telling how quickly he fired off an excessive amount of cum, but by the time she finally managed to pull herself off it, she could feel at least a few gallons sloshing around in her belly, with an appropriate growth around her waistline to indicate what just happened.

Unfortunately for the boy, this just spurred the older woman's lust for him onward. She finally unclamped her legs completely, grinning as a little line of cum-drool ran down her chin. "I'm impressed, really. But if you can cum that much into my mouth, I wonder how much you're going to stain my womb. God, it's been so long since I've been pregnant..." The short but curvy heroine grinned as she let herself fall down on that rod, her lips practically swallowing it whole as she filled the apartment with one powerful scream.

He could feel the very same orgasmic pulse run through his body again, but he didn't cum this time. In fact, he seemingly couldn't There was a pressure that kept the base of his cock pinched together... and upon examination, it made all too much sense. The tanned hero had managed to make her lips clench together, making most of his cock compress inside of her pussy until it could ram up against her cervix with as much potency as possible.

"W-Wait, this can't be allowed, c-can it?" Izuku was lucid enough to ask the obvious question, which prompted a laugh from his temporary teacher. A laugh that had that same underlying lust as the rest of her actions and intentions...

Rumi leaned down, while her lower lips had swallowed that entire cock whole. The fact she remained perfectly still despite it all was actually a bit of a wonder, as she whispered quietly into his ear. "Of course it's not allowed. Why do you think we're in some random apartment? You really think this is where I live?" She chuckled a little as she put a finger on his lips, only to wink as she lifted herself up a little once more, letting the tip of his cock kiss against her lips without any of the pressure those lips put on it. "Come on. Give me one of those 'Smash'es of yours. I wanna see just how much you can pour into me with that inherited power of yours, kiddo."

The boy should feel a little betrayed and used by the way she had set him up, just to cure her of the lust inside of her loins, and to even use him as some sort of breeding bull... And yet, he couldn't work up that anger. She had lied to him, but ultimately she just wanted his help. So why didn't he help her out?

Izuku closed his eyes as he focused his quick into his cock, while the tip gradually got lubed up by the pussy that dribbled juices constantly onto it... only to then SMASH his hips forward, breaking straight through the horny bunny's defenses, shattering her cervix in the process. His rod kept going as it reached all the way into the back of her womb before spreading the entrance to her ovaries open, letting him have a clear shot that would no doubt impregnate her to the extremes.

Despite the pulverizing pleasures that ran through her body as she felt her womb being literally and proverbially smashed, Rumi couldn't feel happier. A massive warm blush from all of her perverted arousal poured onto her face as she could feel her womb and her ovaries twitching, waiting for the storm of cum to blast forth as she was ready to take it all in...

And take it all in was exactly what she did. The boy's balls contracted as their contents fired out with nary a moment to rest. White, sticky baby batter splattered all over the insides of the bunny hero's womb, vaginal canal and especially the passages leading into the ovaries that held every single precious egg of hers. Sperm rushed into those protected egg-holders, only to spear every single egg in seconds. A process that caused explosive pops of pleasure to run through the Pro Hero's body to the point where she could hardly keep herself thinking straight.

Pop. Pop. Pop. Every single solitary egg was filled with an abundance of sperm, making it certain that she was going to be pregnant. Even more so as her stomach bloated outward with all of that wonderful baby batter, making her look even more gravid than a woman who had carried her child to term. In fact, her belly was so large from the sheer amount of cum inflating it, that she could probably use it as an exercise ball if she was careful enough.

Finally, as the rush of cum slowed down, the older woman collapsed on top of the young man, a line of drool running out of the corner of her mouth. She was utterly spent, and she wasn't going to move an inch until she had gathered every little bit of strength by the time she woke up... but that, at the very same time, pinned the boy underneath her for the next while.

A fate that he honestly wasn't that bothered by, but it was going to make his dreams a little too wet. He just hoped that she was happy in the end, due to his roundabout heroic act...

---

Days passed ever since that strange night, and Izuku almost thought that it was a dream. How couldn't he? He woke up in bed all by his lonesome, and his memories of the night were actually quite hazy. He knew that he had done something with the woman he had interned with, but he didn't dare try to visit her to try and confirm if it had truly happened.

One day, while he was busy studying for an upcoming exam, he heard a knock on the door to his dorm room. Upon answering it, he found his jaw-dropping to the floor as he saw the most beautifully shocking sight he had ever witnessed.

Rumi, the Heroine he had interned with, and impregnated on that very fateful night... standing outside of his door, wearing her strained costume around her extremely gravid stomach. A belly that had grown to the point where it made up at least 66% of her size, complete with the sides of it barely fitting into the young man's doorframe. Her breasts weren't far behind either as those milky maternal mounds pushed up and over her belly. They had managed to outgrow head while her nipples dribbled the rich and nutritious white liquid, preparing her for motherhood. Her hips were also quite ready for the time she'd go into labor, as both of them poked out from behind the massive dome she called a gravid belly. Despite the change in size, she seemed much more shy given the blushing expression on her face. Her 'lunacy' had been cured, and she was left with a dilemma much bigger than she was.

"Izuku, I... I have to apologize for what happened that night. I was in heat, you know how it works with animal-type quirks." The brown beauty tiptoed back and forth, before taking a deep breath as she put her hands on her belly, smiling just a little. He could tell what she wanted to tell him, but she wanted him to approve of the situation before she sprung the question.

The green-haired boy nervously smiled, before that smile turned earnest and loving. He had done good, and she repaid his deed by being honest with her feelings and apologetic over what she had done. Why shouldn't he return the favor? He laid his hands upon her own, causing her smile to widen in turn as she spoke up one last time.

"Could you take responsibility for our brood, Izuku..?"

"I do."
