Izuku’s Pro Hero Harem Life!

Summary:

Two years after defeating Shigaraki and overthrowing the Paranormal Liberation Front, Izuku Midoriya is enjoying life as the new number 1 hero with his girlfriend and soon fiancée, Ochako Uraraka, as they lead the way to a brighter future for hero society. Yet many of the women in Deku’s life find themselves at a crossroads, and one after the other begin falling for him, which he and Ochaco find they actually don’t mind.

Summary:

Izuku wakes up outnumbered, but by who?

Notes:

(See the end of the chapter for notes.)

Chapter Text

Waking up, Izuku found himself awash in a feeling of smooth skin. Rubbing the morning crust from his eyes, he tried to sit up but found his body weighed down. He blinked at the sight before him. Even after so much time had passed, he was still amazed that he was able to wake up like this every day.

Sprawled out around and on top of him in the large bed they slept in were a myriad amount of women, each as naked as the day they were born. His girlfriends… God, it sounded weird just saying it in his head, but he liked the sound of it. When he’d met them all those years ago, he could never have imagined that every last one would become involved with him quite like this.

There was Camie resting on top of Jiro, both clasping hands. Mina held Itsuka in a warm embrace, smiling softly as she did so. Her legs were what were weighing atop the left side of Izuku’s chest. Mei and Melissa, who’d taken a liking to one another instantly due to their shared interest in support equipment and technology, had the other’s legs wrapped around their necks. They were rather fond of sixty-nining one another before bed, and the others were careful not to disturb them unless they were in the mood for something a little more adventurous with the others. Normally with Izuku, but they weren’t opposed to experimenting with the other girls when they felt like it.

Tsuyu had her head on Ryukyu’s stomach, the latter of whom already had her legs wrapped around Rumi – this was a bedroom tick of hers – and was resting below Shino, Pixie-Bob (they decided to call her and Ryukyu by their hero names to avoid any confusion) and Tomoko. Moe, meanwhile, had her face buried between Setsuna’s legs and was snoring softly, butt in the air. Setsuna giggled every time her breath tickled her core, unconsciously pressing her closer. Nejire hid her face in the crook of Yuyu’s neck, the both of them holding each other tight. Nemuri was spread eagle in the middle, her stamina allowing her to get to every single girl at least once, and Izuku twice whenever they had one of their group sessions.

Izuku allowed himself to feel a little impressed at their massive polygamous relationship. Even when this whole crazy adventure started, he never imagined it would end up quite this… outrageous. But he figured that with seven quirks at his disposal and having ascended to the top of the hero totem pole after defeating Shigaraki, maybe it wasn’t too far-fetched of a scenario. The girls he’d come to know at school and work were all here with him.

His gaze fell upon Momo by his side, awake with her tender lips curling upward. He moved his hand to rub the small bump that had formed in her stomach. “Hey.”

She brushed a lock of black hair out of her eyes. “Hey.”

“Ready to take on another day?”

“Ready to take on you for sure.”

“Oh really?”

“Really.”

Izuku continued to rub her belly. “Careful, Ms. Number 8 hero. Pretty soon you’re gonna have some more competition vying for my attention.”

“Oh, I’m sure I’ll be able to take care of whatever little monster we’ve created. Are you?”

Izuku leaned in for a soft kiss. “Born ready.”

“Hahaha… Oh, you never change… Ah!”

Just then, Momo’s body jolted. The bed sheets over her crotch shifted, a head bobbing up and down beneath them. Right after, Izuku felt a mouth wrap around his morning wood.

“Oh… Jesus… Well, that’s one way to wake up.”

“Only two missing from what I see… think we can guess who they are by their tongues?”

Izuku chuckled as he shifted Mina’s legs off him. “Okay then, I’ll guess… Toru?”

Momo nodded. “Yeah… this ferocity definitely reminds me of…”

They both flipped up the sheets revealing their bedmates.

“Ochako!”

The rosy-cheeked brunette, her hair now longer than in her high school days, was doing vigorous cunnilingus against Momo’s snatch. She gazed up at her with heavy desire. Toru, invisible she may be, was clearly lathering Izuku’s cock with saliva. Giving it one last peck, she then rose up until her heart-shaped ass sat in front of his rod as she kissed up his jaw.

“Morning, handsome,” she purred.

Ochako was still licking away at Momo’s pussy, the lust on her face and her energetic tongue too much for Momo to bear.

“Oh God… Ohhhh God! Ochako, you’re always too faaaaaaaaaaast!”

Momo came with a small yell, biting the back of her hand to stop. Ochako was panting heavily, her ample breasts (which had grown to rival Momo’s in size as she’d aged) trailing up Momo’s voluptuous frame until she could easily stroke her face. Her belly was also protruding forward, pregnant with Izuku’s first child.

She gently pulled Momo’s hand away from her mouth and gave her the sweetest, most languid French kiss she could muster. Izuku was preoccupied with Toru grinding against his nether region, rocking back and forth in all the right ways. Izuku gave a weary grin.

“I know you guys get horny in the morning, but quite frankly, this is a lot.”

Toru giggled. “It’s all because we love you.” She bent down to kiss him again.

As Ochako and Momo broke their kiss, the latter sighed. “You know we’re not going to be able to do this that often with the kids to take care of, right?”

Ochako giggled, thumbing Momo’s hair. “That’s why I’m collecting right now.” She pecked her lips. “Although who says we won’t be able to find some downtime when we’re off duty?”

Momo sighed contentedly. “I’d like that.”

“But still…” Ochako crawled over to Izuku, eying his dick hungrily. “We need to always be prepared for the main course.”

Murmuring at the commotion, the other women began to stir. Yui had Pony, Ibara and Reiko latched to her slender frame at the other end of the bed. They all blinked groggily. Kaoruko bolted upright, hair a mess as she shook her head. She had hickeys coloring her skin purple up and down her bare neck and chest. Kinoko rose beside her in a similar state, caressing her back.

Rumi’s rabbit ears twitched. “Ohhhh, another morning fuck session? After we exhausted each other last night?” She let a feral grin fall upon her tanned features as she rubbed her own baby bump. “Joining this massive harem of yours has been the best decision of my life.”

Setsuna gasped in pleasure as Moe resumed licking at her right away. “I’ll say!”

Moe pulled her head up to get some oxygen, the tips of her green hair firing up as she did so. “Some of the best heroes in the nation, including Mr Number 1 himself, all in one package? It’s the deal of a lifetime. Doesn’t hurt that you’re all gorgeous.” She bent down again, tongue prodding at Setsuna’s labia with reckless abandon.

Kissing Shino and Tomoko, Pixie-Bob eyed their pregnant bellies lovingly along with her own. Nemuri came over and hugged the three, kissing them all as her own pregnant stomach pressed against theirs. As they were the oldest, they decided to receive Izuku’s seed faster than most of the others. And they weren’t the only ones…

“A shame the others had to skip out on crashing with us last night,” Pony said.

“They have to get ready for our bonds of holy matrimony to be exchanged soon,” Ibara said, holding a quick prayer.

“It’s only a week awayyyyyy! Eek-!” Nejire giggled as Yuyu hugged her close.

It was then that Itsuka and Mina crawled over to Izuku as well.

“Looks like it’s another busy day.”

“Better be ready, Midoriiii!”

Momo sat by Izuku’s head, gently stroking his face. “So? Glad you decided to start dating us all at once?”

Izuku grinned as Ochako inserted herself atop his cock, gently pushing Toru away who acquiesced in letting her go first. Pumping up into his first girlfriend at once, he held her close, her thick thighs wrapping around his waist and her chest smushed against his.

“Do you even need to ask? I love every single one of you.”

Mei turned on a vibrator. “So do I! Want me to prove it?”

Nejire eagerly went over to Mei, pulling her in for a kiss. “We’d love to.”

Yuyu rolled her eyes. “Honestly… always so rowdy in the morning.” Although she didn’t complain when Melissa began gently fingering her and nibbling at her ear, long blonde hair cascading past her face.

With another insane bout of sex upon them, Izuku could only thank whatever powers that be which had allowed him to amass the world’s greatest lovers.

And with that, we go back to where the tale starts about two years ago…

Notes:

Yes. Yes, I'm really doing this. I intend to write the ultimate MHA harem smut fic, all because reading through the others has left me... unsatisfied. There are some great ones out there, some not-so great ones, and a lot that are in the middle or didn't quite do what I've been hoping to see for a while. I wanted to deliver something completely shameless to stand out from the crowd. This isn't going to be like Total Command where it does an overwrite of the MHA world or even has much of an overarching story. Just take this as a crazy AU with a Deku who begins the fic at 20 and is 5'9" tall. (Sorry, super tall muscleman Deku is too off putting for me to ever consider writing.) He's a couple years into being a Pro Hero and got to number 1 in next to no time flat after defeating Shigaraki once and for all who's now in prison, but not before he killed All Might. :(

Deku's first girlfriend will be Ochako, and from there he'll start hooking up with the others, and they'll start hooking up with each other too. I also plan to do separate episodes just focused on femslash which I think there's a severe lack of in this fandom. I'm feeling like doing Ochako/Momo first since there's not a whole lot of those two. Oh, and as you may have guessed, everybody's over 18.

All that said, I might end up doing a sequel down the road with all of Deku's kids that I'll treat more seriously. That'd be fun. But until then, stay tuned for further insanity. Keep an eye on this for updates!

26 girls and that’s final! Not open to adding Toga, this follows the manga storyline too closely for me to feel comfortable writing her even a shade less psychotic than she is in the story. Let the harem begin…

UPDATE: A lot has changed since I wrote this note lol. Lots of extra girls, I'm correcting Ochako's name to the popular spelling. Small adjustments will be made through the rest of the fic including rewriting Fuyumi so she was never in a relationship with Bakugo. Be patient for new chapters and have fun reading!
