My Harem System In My Hero Academia

Yami slammed into Momo's soaking pussy relentlessly, her moans echoing through the house as her thick ass bounced against his hips. 

Her massive tits jiggled wildly with every thrust, droplets of milk spraying onto her stomach and the bed. 

Angela sat nearby, sipping on a glass of wine, watching the scene unfold with an amused smirk.

"Honestly, Momo," Angela said, swirling the wine around like a connoisseur. "You're letting him do all the work. Where's the enthusiasm? If you're going to call yourself a cow, act like one. Ride him properly, or let me show you how it's done."

Momo's cheeks flushed red, and then she nodded and adjusted as Yami flipped her over. 

This time, he pulled her into a reverse cowgirl position. Momo's fat ass pressed against his hips as she began bouncing, her round cheeks slapping against his thighs.

Angela leaned over and gave Momo's ass a playful slap. "Better, but you're still too stiff! Loosen up those hips, girl. Use that ass for more than just decoration."

Yami smirked, grabbing Momo's waist to guide her movements. "You heard her, Cow. Don't embarrass yourself in front of Mom."

Switching positions, Yami pulled Momo onto all fours, her massive tits swaying beneath her as he slid back inside her. His pace was ruthless, each thrust making Momo moan in pleasure. 

Angela, still critiquing, leaned in close and pinched one of Momo's leaking nipples, causing Momo to squeal.

"You're spilling milk everywhere," Angela said with mock disappointment, catching the stream with her tongue. "How will you be a proper cow if you waste the goods? How could you ever begin to be half the wife I am?"

Next, Yami moved Momo onto her back, folding her legs up toward her shoulders in a mating press. 

Her thick thighs pressed against his torso as he drove into her deeper than before, his cock twitching inside her. Angela, watching from the side, reached down to play with her own dripping pussy, enjoying the show.

"Now that's what I like to see," Angela said, licking her lips. "He's absolutely ruining you, Momo. But you need to hold those legs higher. Let him get in even deeper."

Momo whimpered, doing her best to follow Angela's instructions, her body trembling as Yami filled her over and over. 

Angela leaned down and suckled at Momo's tits, drinking the sweet milk as Yami pounded her mercilessly.

For the fourth position, Yami lifted Momo off the couch, holding her by the ass as he fucked her standing up. Her legs wrapped tightly around his waist, her arms clinging to his shoulders for balance. 

Angela stood behind Momo, her hands squeezing Momo's ass as she whispered tauntingly into her ear.

"See? Now you're doing something useful," Angela said, giving Momo's ass a firm slap. "Let him know you're actually enjoying yourself."

The final position had Yami lying back on the bed while Momo rode him in a traditional cowgirl position. 

Her hips moved erratically, her massive tits bouncing wildly as she desperately tried to milk his cock for everything it was worth. Angela, sitting behind her, guided her movements with her hands on Momo's waist.

"See? That's how you do it," Angela said, her tone smug. "Now, if only you weren't so clumsy. You've got the body, but you lack the technique. Keep practising, and maybe you'll be worth being his first wife."

By the time they finished using the tenth condom, Momo collapsed onto Yami's chest, her body drenched in sweat. 

Angela cuddled up beside him, resting her head on his shoulder. The three of them drifted off to sleep.

The next morning, Yami woke up first. Momo and Angela were sound asleep, their soft, warm bodies pressed against his. 

He carefully slid out of their vice, letting them rest, and headed to his father's—his own study to get some work done.

As he opened a book on Quirk applications, the system popped up with its usual obnoxious timing.

[Well, don't you have two sluts to milk?] the system chimed. 

[But hey, I thought giving you a flashy new ability wouldn't hurt anyone.]

Yami rolled his eyes as the system continued.

Yami stared at the screen, his golden eyes narrowing. "Of course," he muttered to himself. "Because nothing's ever simple with you."

[Fuck you! Stop whining like a little bitch and just go around sticking your cock in crazy like a proper man.]

[...]

[Then again, on second thought, maybe don't stick your cock in crazy just yet. There are some terrifying monsters out there. Better keep it in your pants for now.]

[Anyway, Angela's been missing having brats running around the house. She was planning to ask you to knock her up by the end of the month, so really, I'm doing you a favour, you spoiled brat.]

Yami groaned and dismissed the obnoxious system message. 

It had a way of getting on his nerves, but this time, it wasn't entirely wrong. 

Angela had mentioned how quiet the house felt sometimes, and she'd been spending more time tending to her garden, looking lost in thought. Maybe there was some truth to it.

After shaking off the distraction, Yami focused the next two hours on his studies. His sharp golden eyes scanned page after page, absorbing information like a sponge. 

The peaceful quiet was only broken when the sound of bacon sizzling and the faint smell of omelettes drifted up from downstairs.

Yami stretched, his muscles flexing as he stood, and headed to the kitchen. 

When he stepped in, the sight that greeted him made him pause momentarily. Angela and Momo were busy at the stove, both wearing cow-print bikinis. 

Their wet hair hung loose, glistening in the morning light, and it was clear they'd just showered.

Angela was humming softly as she flipped a slice of bacon, her massive chest barely contained by the skimpy top. 

Beside her, Momo was focused on the omelettes, her thick hips swaying slightly as she worked. 

Her cheeks were flushed, though Yami couldn't tell whether it was from the heat of the stove or something else.

"Good morning, Yami!" Angela greeted him cheerfully, turning to smile at him. 

Her warm expression softened even more when she added, "Momo's an amazing cook. I don't think I've ever had such perfectly fluffy omelettes before."

Momo glanced over her shoulder, her cheeks turning a deeper shade of pink. "Oh, it's nothing special," she said modestly, brushing a strand of dark hair behind her ear. "It's just part of my family training. Cooking, table manners, etiquette—it's all expected."

Angela laughed, her wide hips swaying as she placed a plate of bacon on the table. "Well, Yami, it looks like you found yourself a good first wife," she teased, her tone playful but warm.

Yami smirked, stepping closer to Angela and wrapping his arms around her waist. His hands slid up, cupping her massive tits as he leaned in. "A good wife, huh?" he murmured, his voice low and teasing. "What about you, Angela? Ready to make me a dad?"

Angela hesitated, her blue eyes flickering with a mix of emotions. For a moment, she seemed unsure, but then her lips curled into a soft smile.

"Maybe I am," she admitted quietly, her voice barely above a whisper. "I've been thinking about it lately... about how nice it would be to have kids running around again."

Momo finished plating the omelettes and set them on the table, her face still red as she glanced at the pair. "If that's what Yami wants, then I agree," she said softly, her tone full of devotion. "I'll support whatever decision you make."

Yami let out a deep chuckle, pulling Angela closer and kissing her neck. "Well, that settles it," he said, his golden eyes glinting with satisfaction. "Guess we've got some work to do."

Angela swatted his chest playfully, though her cheeks were red like Momo's. "Eat your breakfast first, you animal," she said, laughing.

Yami sat, watching as Angela and Momo joined him at the table. After a brief lunch, Yami and Angela walked back upstairs.

Yami and Angela didn't even reach the bedroom before their clothes were torn off and tossed across the room. 

Angela's fat tits spilt free as she yanked off her bikini top, her nipples already hard and leaking from excitement. 

She grabbed Yami by his cock, her fingers stroking his thick cock as she pulled him toward the bed.

"Yami," Angela moaned, her voice dripping with need. "I want you to fuck me raw. Fill me up, ruin me. Don't hold anything back, fuck me as you will fuck your wifes~."

Yami didn't waste time with sweet words. He shoved her onto the bed, spreading her thick thighs apart as he lined himself up with her dripping pussy. 

Her fat ass jiggled as she squirmed beneath him, desperate for him to shove it inside her.

"You want it that bad, huh?" Yami teased, slapping the tip of his cock against her soaked lips. Angela whined, reaching down to spread her pussy lips open for him, her juices already running down her thighs.

"Stop teasing me and fuck me already!" she cried, her nails clawing at his arms.

Yami smirked and thrust into her in one brutal thrust; her tight pussy swallowed him whole. 

Angela screamed his name, her nails digging into his back as he started pounding her like a wild animal. 

Her tits bounced violently with every thrust, milk spraying everywhere as Yami squeezed them roughly, drinking the warm liquid straight from her nipples.

"Fuck, you're so tight," Yami growled, slamming into her harder, his balls slapping against her fat ass. "I'm gonna breed you, Angela. I'm gonna pump you so full of cum, you won't be able to think about anything else."

Angela moaned like a bitch in heat, her legs wrapping tightly around his waist as she begged for more. "Do it, Yami! Fill me up! Knock me up with your babies! Make me your breeding bitch just like Momo!"

Yami grabbed her by the hips, lifting her ass off the bed so he could fuck her even deeper. 

Her pussy was so wet, his cock slid in and out with obscene squelching noises. 

The bed creaked and groaned under the force of his thrusts, but neither of them cared. All that mattered was the way Angela's insides gripped him like a vice, milking him for every drop of cum.

When Yami finally came, he didn't pull out. He buried himself as deep as he could go, his cock throbbing as he pumped her full of hot, sticky cum. 

Angela's belly started to swell immediately, bloating with the sheer volume of his load. She looked down at herself, her hands resting on her cum-filled stomach, and let out a shaky moan.

"More," she whispered, her eyes half-lidded with lust. "I need more."

Yami flipped her onto her hands and knees, her fat ass high in the air. He slapped her cheeks hard, watching them jiggle before plunging back into her sloppy, cum-filled pussy. 

Angela cried out, her face buried in the pillows as Yami fucked her even harder than before. His cock stretched her open, his cum spilling out and dripping down her thighs, but he didn't stop.

"You're such a greedy slut," Yami said, gripping her ass as he pounded her from behind. "Look at you, begging for more. You'll take every fucking drop I give you."

Angela moaned louder, her voice muffled by the pillows. "Yes! I'm your woman, Yami! Use me, breed me, fill me with your fucking cum!"

By the time Yami came for the ninth time, Angela's belly was so swollen she looked like she was already four months pregnant. 

Yami used his quirk technique, [Population Control], to make sure every last was as probable to impregnate as possible.

As Yami pulled out, Angela collapsed onto the bed, her body trembling. Cum leaked out of her gaping pussy, pooling on the sheets, but she still wanted more. 

She rolled onto her back, spreading her legs wide as she looked up at him with a desperate expression.

"Don't stop," she begged, her voice hoarse from screaming. "I need you to keep fucking me. I need more of your cum, Yami. Please."

Yami smirked, stroking his cock as he positioned himself over her. "You're insatiable, aren't you?" he said, sliding back inside her. "Fine. I'll give you more. I'll fuck you until your pussy can't take it anymore."

And he did. Yami fucked Angela relentlessly, pouring load after load into her until her stomach was bloated to the point of absurdity. 

Her body was drenched in sweat and covered in milk and cum, her tits sore from how much he'd sucked on them. Yet she still begged for more, her voice hoarse but determined.

Meanwhile, Momo stayed downstairs, ignoring Angela's screams and the bed creaking. 

She spent the day reading her favourite books and practising kendo, occasionally glancing at the clock to see how much time had passed. 

She knew Yami and Angela wouldn't stop soon, so she kept busy.

But occasionally, Momo's thoughts would drift to what was happening upstairs. She imagined Yami's cock stretching Angela open, his cum filling her womb until she couldn't take anymore. 

Her cheeks flushed at the thought, and she quickly shook her head, focusing on her kendo drills.

When evening came, Yami emerged from the bedroom, his golden eyes gleaming with satisfaction. He looked down at Momo, still practising in the living room, and smirked.

"You're up next, Cow," he said, walking past her toward the kitchen. "Get ready."
