My Harem System In My Hero Academia

It was early morning, and Yami's cock was still buried deep inside Momo as he fucked her relentlessly in the living room. 

The house reeked of sex—a disgusting cocktail of cum, sweat, and Momo's constant squirting. 

Every surface was drenched in filth. The couch, the walls, even the damn kitchen table where they had eaten dinner last night—everything was stained with their fluids. 

They hadn't stopped fucking since last night, and Momo's pussy was wrecked beyond recognition, her swollen pussy lips stretched raw from taking his cock over and over again.

Yami had her in a full nelson, his hands gripping her thighs as he jackhammered into her cunt from behind. 

Her tits bounced wildly with every thrust, heavy and smeared with dried cum from his earlier loads. 

Her bloated stomach jiggled as he pounded her, sloshing with the obscene amount of semen he'd dumped into her womb. 

She looked pregnant, her belly round and swollen, and yet she still begged for more like a cock-starved whore-cow.

"Don't you fucking dare pull out!" Momo moaned, her voice hoarse from screaming all night.

Her pussy clenched around him, her juices dripping down his balls and pooling on the floor. 

She was beyond fucked—her mind completely lost in the haze of lust. Her face was a mess, mascara smeared, drool leaking from the corner of her mouth as her eyes rolled back in pure cock-drunk bliss.

Just then, the front door creaked open.

Angela walked in, the click of her heels echoing through the house. She immediately caught the overwhelming stench of sex and spotted Yami still slamming into Momo like a bull to a cow. 

Cum dripped from Momo's abused pussy, splattering the floor with every brutal thrust. Angela smirked, not at all surprised by the filthy scene before her; she had been in the same position as Momo, quite literally.

"Still going at it, huh?" Angela teased, setting Momo's freshly pressed U.A. uniform down on a dry spot on the floor. 

Her green eyes lingered on Momo's cum-stuffed belly and the way her pussy lips clung to Yami's cock with each pull.

Yami didn't slow down. His cock pistoned in and out of Momo's soaked hole, each thrust making her tits jiggle violently. He glanced over at Angela, smirking through gritted teeth.

"Morning, Mom," he grunted. "You're back early."

Angela chuckled, walking closer, her hips swaying with each step. Her black kimono was as spotless as ever, and her massive tits threatened to spill out as she leaned against the couch.

"I'd join you," she said, biting her lip as she watched Yami pound Momo into oblivion. "But you've got your first day at school today. Time to get ready, sweetheart."

Yami groaned in frustration. His cock twitched inside Momo, the tight grip of her cunt refusing to let go. 

He slammed into her one last time, grinding balls-deep as he pumped another thick, boiling load into her already overflowing womb.

Momo screamed, her whole body convulsing as she squirted again, soaking Yami's thighs and Angela's face and kimono. 

Momo's belly bulged even more as his cum filled her to the brim, and her pussy twitched uncontrollably around his cock, milking every drop.

When Yami finally pulled out, a flood of creamy cum gushed from Momo's stretched hole, dripping down her thighs and onto the floor. 

She collapsed onto the couch, panting like a cow in heat, her legs spread wide and trembling. 

Her pussy lips were red and swollen, still twitching from the abuse.

Angela raised an eyebrow. "You're really going to leave her like that?"

"She's fine," Yami said, wiping the sweat from his forehead. He glanced down at Momo, sprawled out on the couch, surrounded by crumpled tissues and puddles of her own squirt.

"Fuck…" Momo whimpered her voice barely a whisper. "I can feel it… sloshing inside me…"

Yami chuckled, reaching down to pat her swollen belly. "You're lucky I don't keep going."

Momo's glazed eyes met his, a cock-drunk smile spreading across her face. "I'd let you… Keep fucking me, Yami… Please…"

Angela laughed softly, shaking her head. "You two stink. Now go shower before you're late."

Yami bent down, scooping Momo into his arms. Her body was limp, her tits pressed against his chest as he carried her to the bathroom. 

Cum dripped from between her legs with every step he took.

In the bathroom, Yami set Momo down gently. Momo leaned against the wall, her legs trembling as more of Yami's cum leaked from her pussy, splattering onto the tiled floor.

"I need a plug," Momo muttered, her fingers dipping between her legs to scoop up the leaking cum. "I can't go to school like this…"

Yami turned on the shower, adjusting the water temperature before stepping in. He grabbed Momo by the waist, pulling her into the water spray.

"Then make one," he said, his hands roaming over her wet body, squeezing her tits and ass. "Keep my cum inside you all day."

Momo moaned softly, using her quirk to create a small, flexible plug from the fat stored in her stomach to make it less bloated. 

She slid it into her pussy, gasping as it locked in place, sealing his cum inside her.

"It's sloshing around," she murmured, pressing a hand to her belly. "I can feel it… flowing from my womb back into my pussy…and then back into my womb..."

Yami smirked, leaning in to bite her neck. "Good. Keep it there."

After their shower, Momo's belly wasn't as bloated, but she still had a slight tummy. 

Her U.A. uniform hugged her curves tightly, the skirt barely covering her thick ass. Her tits strained against the blazer, and the plug in her pussy made her squirm with every step.

Downstairs, Angela had cleaned up most of the mess in the living room and prepared breakfast. The smell of grilled fish and rice filled the air.

"Eat up," Angela said with a smirk as they sat down at the table. "You'll need your strength."

Yami glanced at Momo, who took a bite of her rice, her cheeks flushed. His golden eyes darkened with lust as he watched her squirm in her seat, feeling his cum sloshing around inside her.

Yami chuckled, already feeling his cock twitch in anticipation. Still, for the sake of not being late, he decided to just enjoy the rest of the day as a normal couple on their first day of high-school.

[My man... Sniff~]

After Momo called her limousine, it pulled up right in front of U.A. 

The ride had been quiet, except for Momo constantly fidgeting in her seat, her thighs pressing together as she tried to ignore the steady sloshing of Yami's cum inside her. 

Her plug was doing its best to hold everything in, but every little bump in the road made her feel the still hot, dense and thick liquid move inside her, making her squirm.

Yami noticed, of course. How could he not? He could see the faint twitch of her legs and the slight blush on her cheeks. 

But he didn't say anything. He just smirked to himself, thinking about how tight she had felt the night before, how her pussy had sucked him in like it never wanted to let go. 

The thought made his cock twitch in his pants, but he pushed it aside. There would be time for more later.

When the limo finally pulled up in front of the massive school gates, Momo stepped out first, adjusting her skirt and blazer. 

Yami followed, his golden eyes scanning the school grounds. It looked just like he remembered from the manga—tall buildings, clean pathways, and that H shape.

As they walked through the entrance and looked for their classroom, Yami couldn't help but think about how surreal it all felt. He was actually here, standing in front of Class 1-A. The place where the story really kicked off.

But everything suddenly stopped before he could open the door for him and Momo.

The world around him turned black and white. Even the gentle breeze rustling the trees outside stopped as the world stood still.

"Sup, Zuko here," a voice echoed in Yami's head.

Yami froze, his eyes widening—if they could wide in the stopped time. 

He hadn't heard that voice in years. 'Snail?' he thought.

"Yup, it's me," the voice continued, sounding smug. "Just wanted to drop by and let you know I made some balance patches to the world. Gotta keep things interesting, you know? Some villains will have new abilities or be mixed up with other franchises, and you might run into a few original characters I cooked up. Don't worry; the system will keep you up for the details."

Yami groaned in his mind, 'You're messing with the world again?'

"Of course! How else would I make the U.A. girls more fuckable and the age gap less awkward, anyways? Gotta go." 

"Good luck, champ. Oh, and by the way… keep an eye on that cow of yours. She's gonna need a bigger plug soon."

And just like that, everything snapped back to normal.

The world regained its colour, and the sounds of the school filled the air once more. 

Yami shook his head, trying to process what had just happened. 'Fucking Snail,' he thought, sighing as he finally stepped into the classroom.

Class 1-A looked exactly how he remembered it from the manga—neat desks arranged in rows, a large blackboard at the front, and wide windows letting in natural light. 

He and Momo were early, so the room was mostly empty, with only a few students scattered around.

What immediately caught Yami's attention, though, was the seating chart displayed on the wall.

His eyes scanned the list, noting the familiar names. Bakugo. Midoriya. Todoroki. But then his gaze landed on Seat No. 19.

Iwatani Yami.

Right next to Seat No. 20: Yaoyorozu Momo.

Yami smirked. "Guess we're stuck together, huh?" he said, glancing at Momo, who was still fidgeting uncomfortably.

Momo nodded, her cheeks pink as she adjusted her blazer again. "Looks like it."

Yami kept scanning the chart, curious about who had been moved around to make room for him. That's when he noticed it.

Mineta.

The little purple pervert was sitting in Seat No. 9, which originally belonged to Koda...Koda, the quiet guy who could talk to animals. 

Yami frowned. He hadn't seen Koda anywhere. 'Had Snail erased him from existence or something?'

He glanced toward Mineta, who was busy ogling the few female students as they walked in. 

The rat's eyes lingered a little too long on Momo's legs, making Yami's jaw clench.

'This fucker better not get any ideas,' Yami thought, already feeling the urge to punch Mineta square in the face.

As more students trickled in, the classroom quickly filled with chatter.

Bakugo stomped in, looking pissed off as if someone had fucked his mother... 'Maybe another day'. 

Todoroki entered quietly, his brown and blue eyes scanning the room before taking his seat.

Yami leaned back in his chair, watching it all happen. It felt strange seeing these characters come to life right in front of him, well, a little less since he had been fucking with one of them just a night earlier. 

Momo shifted in her seat beside him, crossing her legs tightly. Yami noticed how her thighs pressed together, the subtle twitch of her hips.

"You good?" Yami whispered, leaning over slightly.

Momo nodded quickly, her cheeks turning an even deeper shade of red as Yami's face was a little to close to hers. "Y-Yeah. Just… adjusting."

Yami smirked. "Adjusting to what? The seat or the plug?"

Momo shot him a glare, but no real heat was behind it. "Shut up."

Before Yami could tease her further, the classroom door slid open as Midoriya and Bakugo fought, and a familiar, tired-looking man walked in.

Aizawa.

The Pro Hero, known as Eraserhead, strolled to the front of the class, his messy black hair covering part of his face. He looked exhausted as if he hadn't slept all night.

"Alright, everyone. Settle down," Aizawa said, his voice monotone. "I'm your homeroom teacher, Aizawa Shouta. Welcome to U.A."

The students quickly quieted down, all eyes on their new teacher.

"We're not here to make friends or have fun," Aizawa continued. "You're here to become heroes. And that means we'll push you to your limits daily."

With a sigh, Aizawa took a Gym U.A uniform and held it up for everyone to see, "Quickly now, change into your gym clothes and head to the grounds."
