“Nmmmmmhmmmmh…” purred Setsuna Tokage as she lay her head against Izuku Midoriya’s chest. Both of them were covered in a thick layer of sweat, and the sheets of the bed they lay on were all but soaked. Not to the point that any movement made a squishing sound, but definitely to the point where the fabric liked to cling to their skin.

 

The green haired young woman planted a few gentle kisses on Izuku’s bare chest, and he turned his gaze from the ceiling down to her. She was beautiful, with her wavy, dark green hair, dark colored eyes, and even her shark toothed grin, all were part of her overall charms. The two of them were currently on the fourth floor of the Busteez Hero Agency. One of the nice, regular rooms, not the illusioned suites Camie maintained. Izuku had run into Setsuna as he came in after working his shift at the Endeavor Agency. It had been a mostly quiet day, a couple attempted purse snatchings was all the area he was assigned to had to offer. Ka-chan had to deal with a gas main explosion on the other end of town which still had leftover infrastructure damage from AfO’s rampage. His friend had cleverly put out the flames by setting off a blast that for just a second blew away all the air around the flaming pipe.

 

Izuku tried to suppress a wince at the way Ka-chan laughed as they put in their reports. Burnin had given him a solid knock to the back of his head for that though.

 

“HEY! It’s a GOOD thing when there’s nothing to report aside from some petty crimes! It means we’re doing our job well!” she had chided him. “I’ll take a purse snatcher over All for One any day of the week!”

 

“What’cha thinking ‘bout, Dekun?” Setsuna asked, snapping him back to the present.

 

“Hmm, nothing much. Just remembering earlier today, and admiring how pretty you are.” he said with a smile.

 

Her cheeks flushed just slightly, so slightly he might not have even noticed before they officially got together and began spending more free time with one another. She reached up and flicked his nose playfully. “Normally, flattery like that will get you everywhere, but we’ve already ruined these sheets.” she told him. “Oh…!” she then squeaked as Izuku put his arms around her narrow waist in a gentle embrace. She snuggled into his arms, letting out a soft sound that was somewhere between a cat’s purr and an erotic moan.

 

“Nmmmmm, someone has really upped his Rizz Levels!” she giggled.

 

“Eh?” Izuku responded, “What’s Rizz?” he asked.

 

“Something I heard from Camie. I think it means your romantic skills most directly translated, or just raw sex appeal, or both. Honestly, I don’t speak Gyaru fluently, so gotta use context a lot with her.” Setsuna explained. “And even then, I only understand her maybe three fourths of the time.”

 

“Ahh.” said Izuku. He actually owed Camie a lot. Were it not for her, he’d never have asked Momo out that one time, and he wouldn’t be in bed with Setsuna now. Momo was actively building a full blown Harem for Izuku, like one of those silly romcom manga. She had explained it as she wanted that big “sisterly” kind of family centered on a man they all loved.

 

Izuku had been very hesitant at first, but the idea had grown on him. Though it did have some drawbacks. Whenever his girlfriends wanted something collectively, his own opinion had ceased to matter.

 

“So, what’s the plan for tomorrow?” Setsuna asked, jarring him out of his thoughts again.

 

“Huh, tomorrow?” Izuku asked, blinking his eyes in confusion.

 

“It’s July 15th? Your birthday?” Setsuna responded, “Wait, did you ACTUALLY forget? I thought that was a Manga joke!”

 

Izuku thought for a moment, “Huh, you’re right! I think I did! Or more, I lost track of the days for a bit.”

 

“Wow, you know, it’s OKAY to be selfish every now and then!” Setsuna chided him.

 

“I think having seven girlfriends might be selfish enough, aheheh…” Izuku chuckled.

 

“Eight.” Setsuna corrected.

 

“Huh?” replied Izuku.

 

“You have eight girlfriends, not seven.” she explained.

 

“Wha… Hold on…” Izuku said as he brought up both hands, “You, Momo, Ochaco, Tsu, Toru, Rie, and now Kaina makes seven,” he said, sticking up a finger for each name he counted off, “Who’s the eighth?”

 

Setsuna gave him a wide, predatory grin that showed off her shark-like teeth, “Mitsuki. She said she wanted to join after that thing with Kaina a couple days ago.” Setsuna told him. She then began laughing as Izuku turned to stone so fast, he could actually feel his body cracking from how sudden it was.

 

“AHAHAHAHA, the look on your face!!!!” Setsuna laughed hard, slapping a hand down on his chest, tears actually beading at the corners of her eyes.

 

“But, Mitsuki, I mean, she’s married, and Ka-chan’s mom, and she has a husband, and…” Izuku stammered, repeating the same two points like a broken record.

 

“Relax, relax…” Setsuna said, still trying to stop herself from laughing, “I’m only kidding! Well, mostly. I don’t know what I saw her and Momo talking about earlier, so you might wanna prepare yourself for that!” she warned, “No, the girl I meant is… Actually, know what, I’ll keep it a surprise for tomorrow!” she said with that same grin. “All the other girls are gonna be busy with actual hero work, right?”

 

Izuku thought for a moment. Aside from Setsuna herself, ALL of his other girlfriends were busy with work for the next few days. Momo had seemed a little bummed about so many of the girls being busy for some reason, and now he knew why. “You’re right, but it’s not like we have to celebrate it on the actual day, I’m fine waiting until everyone is free.” he told her.

 

“Gnope!” Setsuna replied, making an “X” with her index fingers, “M’kay, since you really didn’t have anything already planned, my idea will work then!” she said with that same shark-toothed grin that made her look so cute.

 

“And what’s that?” Izuku asked, his interest peaked.

 

“It’s… A… Secret!” she replied with a giggle.

 

---

 

“GHEEEP!” Izuku gulped loudly at the sight that greeted him when he walked into the suite Setsuna had told him to come to. It was an illusioned room by Camie where everything was done up in a swirl of colors that were constantly moving, meant to give the place a kind of dream-like quality.

 

Waiting inside the room were four beautiful naked women, three of them grinning like the Cheshire Cat, one who looked a little nervous.

 

“Awww, what’s that look for? Don’t most guys dream of this sort of thing?” asked Rumi Usagiyama as she leaned forward in a way that showed off her huge tits.

 

“Yeah, I’d have thought you’d be used to this by now!” added Mina Ashido, who stood in a way to show off her pink ass.

 

“Oh, he is. He’s had four of us at once before.” Setsuna said as she gave him a wave, “Happy Birthday, by the way!”

 

“Um, happy birthday, Sir Izuku.” said the fourth girl in the room. Someone Izuku didn’t know extremely well, but he’d seen her many times both in school and on the main stage in the ballroom. Ibara Shiozaki, of class 3-B. She had a quasi heteromorphic quirk in the form of her hair being made of thorny vines. Quasi in the manner of it was a permanent fixture that she could not change. She wasn’t as extreme as other heteromorphs like Shoji and Koji, or a woman he briefly met during those months he was out on his own, acting as bait for AfO.

 

“I hope you will find me satisfactory.” Ibara said.

 

“Girl, relax!” Setsuna said, moving to drape her arm around the vine haired girl’s shoulder, “I thought you weren’t all hung-up on pre-marital stuff anymore?”

 

“I’m not. It’s just, well, the other girls are a lot prettier…” said Ibara.

 

“Nah girl,” said Mina, giving a thumbs up, “That bod is hawt!”

 

“Agreed.” said Rumi.

 

“Thank you all. I hope the Lord will bless our union today!” Ibara said, clasping her hands together in a prayer pose.

 

“Eh, I’m a little lost.” said Izuku.

 

“Set-chan here filled us in on most of your harem being out for your birthday. A guy who saves the world deserves a proper group of sexy ladies for his birthday!” explained the rabbit eared woman. “And Melissa is away with Cassie visiting her dad in the States, and honestly, I’m horny as fuck! So I agreed on the spot!”

 

“I’m still cross on being cockblocked that last time.” said Mina with a slightly sour look.

 

“And Ibara here has just signed on as the latest girlfriend!” Setsuna announced, “Surprise!” she said with a cheeky grin while doing a “V” with her fingers.

 

“EEEHHHHH!?” exclaimed Izuku.

 

“Yeah, that’s news to me.” said Mina, “You do know what a harem is, right, girl?”

 

“Well of course I do! Many figures in the bible had multiple wives and concubines! There’s no shame in it at all.” Ibara said, “King Solomon himself had seven hundred wives and three hundred concubines!”

 

“Damn, and I thought I was horny!” Rumi said with a hearty laugh. “I don’t even think you could bang all those girls in a calendar year!”

 

“Nah, it’s doable.” said Mina, “Just not much time for anything else, so doing kingly stuff would be difficult.”

 

“Yeah, guy must’ve died from dehydration!” Rumi laughed.

 

“Actually, he died of natural causes around fifty-five years of age after a forty year reign.” Ibara said.

 

“Dehydration is a natural cause.” Rumi said.

 

“Oh, I guess it is…” the vine haired girl conceded.

 

Setsuna clapped her hands loudly, “Riveting as that subject is, we’re here for Dekun!”

 

“She’s right. Come on punk, pick whichever one you want!” said Rumi, still grinning, “But, if you can’t pick, we can just all go at once!” she said, moving to strike a pose that showed off all her curves. Her huge tits bounced and jiggled enticingly, she’d clearly been to see Rie before coming here today. “After all, isn’t a harem every man’s dream?”

 

“It certainly is Mineta’s.” Mina giggled, “I swear he cries bloody tears whenever someone brings you up, Izuku.”

 

“Oh, that short guy?” Rumi asked, “He’d be cute if he wasn’t so open with his pervertedness.” she said, “Don’t get me wrong, it’s good when a man knows what he wants. But a little discretion is sexy too.”

 

Ibara then moved away from the group of naked women, stepping closer to Izuku. Close enough that he could smell her, a rich earthy aroma with a hint of moisture, like when you first walked into a botanical garden. The vines that were her hair snaked out like tentacles, lashing around his wrists, ankles, and waist, pulling him closer to her like he weighed nothing.

 

What surprised Izuku most though wasn’t the sudden aggressive move from the normally demure girl. But more that the vines that made up her hair didn’t FEEL like vines at all. They had a smooth feel to them, like silk, but also kind of like rubber. More than that, the thorns that grew on those vines weren’t sharp at all, so Izuku could feel several of them pressing against his skin, but they didn’t scratch or cut into him in any way.

 

“I can control when they get sharp.” Ibara said when she saw him looking at the vines around his wrist with confusion. She then reached up and grabbed his face with both hands. “Excuse me.” she said before pressing her lips to his in a surprisingly tender kiss. She pressed her naked body against him, and Izuku felt the vines entwinning his wrists loosen enough to let him move his arms freely.

 

So he slipped those arms around the vine haired girl’s slender waist. Ibara jolted slightly, startled, but quickly relaxed in his arms. He felt her slip her own around his shoulders, hugging him tightly as their tongues met. The young woman made a soft noise that was both a gasp and a moan at the same time somehow. She then began sucking roughly on his tongue, as if she were trying to drink him in, moaning against his mouth as he moved one hand to gently caress her rounded ass.

 

“Haah…!” Ibara gasped, finally breaking the kiss and sucking in a breath as if she had been holding it for the entire duration. She then leaned her face close to his, pressing her cheek against his own, “Please, Lord Izuku, take me as your lover and one of your wives.” she whispered very softly, her breath tickling his ear.

 

Izuku responded by moving to kiss and nibble her neck, and Ibara moaned as if she were having an orgasm!

 

“Now we’re talking!” Mina said excitedly. All four women gently escorted Izuku over to a large mound of glowing light, it was an illusion of course, Camie’s work. Izuku knew from the cookie cutter layout of the rooms Camie enchanted for lack of a better term, that this was actually the bed.

 

Rumi yanked off the top cover, revealing the actual mattress beneath the illusioned blanket, which made it easier for everyone to climb into the bed. The green haired young man was quickly stripped by all of them, his clothes sent flying in all directions.

 

“Oh, oh myyyy…!” Ibara gasped when she saw his naked body.

 

“Yep! Could grate cheese on these abs!” Rumi said, rapping her knuckles against his belly.

 

“I think she meant this more.” Mina said, grabbing Izuku’s dick which was already rapidly swelling to its full size. “No one here’s gonna cock-block me, right?” she asked with a slightly bitter tone.

 

Setsuna giggled, “Nah girl, you can…” she didn’t finish her sentence before Ibara moved quickly, shoving Izuku down onto his back and quickly mounting his dick!

 

“H-hey!!!” Mina protested, puffing her cheeks in annoyance.

 

“Ahhhnmmmmmh, soooo… Thiiiick…” Ibara moaned, rubbing her hands over her now distended belly, the size of Izuku’s cock making a distinct phallic shaped lump in her abdomen.

 

“Feels like you’re being split in half, right?” Rumi asked with a wide grin.

 

“Ahhhhnnn, ye… Yesss, but it feels so gooood!!!” Ibara moaned, resting her weight on her knees as she straddled Izuku. She then used her legs like a hinge and began rocking herself up and down on his length. “Ahhhh, yes, this… This feels so amaaaazing!! I’m… I’m making love the way Lilith wanted to, ahhh, I’m so sinfuulllll!!!” she moaned.

 

“Oh please, girl, cowgirl is TAME!” said Rumi, “And Missionary is boring. Well, most of the time.”

 

“I dunno, I kinda like looking up at a guy when he’s plowing me!” said Mina.

 

Izuku mostly ignored their commentary as he reached up with both hands, gripping Ibara’s big, soft tits, squeezing them firmly. “OOOOHH!!! YES LORD, AHH, TAKE MEEEEE!” she moaned, her voice louder now as she surrendered to her desires.

 

Izuku sat up, still holding onto Ibara’s heavy breasts as he latched his mouth onto her left nipple, sucking on it roughly. Ibara’s reaction was instant as she let out another long and loud moan of pleasure and began rolling and swirling her hips against him, stirring his dick around inside herself!

 

He groaned, enjoying the warm, tight, wetness of her pussy as he began gently bucking his hips into her movements. A wet, lewd, squishing noise could be heard of the vine haired girl’s moaning as she began breathing heavier.

 

“AHHN, YES, PLEASE DON’T STOP!” Ibara screamed, “AHH, PLEASE, PLEASE, PLEASE, PLEASE KEEP GHOOOOING!!! AHHHN, I… I… AHHHNNNMMMMH!!!” Ibara panted and moaned, her entire body shaking as Izuku moved from one nipple to the other, swirling his tongue around the hard circle of flesh. He could feel her entire body clenching all at once as she came hard, her pussy spraying all over his groin.

 

“Wow, seriously?” asked Mina, “Just from that much?”

 

“Ibara mostly does the dance floor and such. Not a lot of experience with the more ‘active’ jobs.” explained Setsuna.

 

“Please don’t tell me she’s a…” Rumi said, letting the sentence hang, but Izuku wasn’t naive enough to miss what she was implying.

 

“No,” both he and Setsuna said together. “Not a virgin.”

 

Mina giggled, when they both looked at her, she got herself under better control, “Nothing. It’s just cute, the way you said that together.” the all pink girl told them before she crawled over to Izuku and Ibara on the bed, “‘Kay, MY turn!” she said, helping to gently extricate the vine haired girl from Izuku. Ibara was still shaking, a lewd expression on her semi-conscious face.

 

“OOOOOOHH, YEEEEEAAAAAH!!!” Mina howled as Izuku pushed her down on all fours like a beast and shoved his dick inside her! Once Ibara was off him, he moved quickly, getting the all pink girl into position and pushing inside her all in one smooth, almost fluid motion.

 

“FUUUUUUUUCK!!! THAT DICK IS SO BHIIIIIIG!!! I CAN FEEL IT FORCING ITSELF INTO MY WOMB!!! AHH YEAH, POUND THAT BITCH BREAKER INTO MHEEEEEE!!!” Mina screamed, rocking herself back into him as he started moving his hips. He pulled the thick length of his cock back, until he was only halfway inside her, then shoved it back inside with a loud and slightly moist ‘PLAP’!

 

PLAP! PLAP!! PLAP!!!

 

With every movement, Izuku got rougher and more forceful, until the room was filled with a loud almost machine gun PLAP PLAP PLAP PLAP PLAP sound!

 

“HWEEEEEEEEGH!!!! YES!!! THAT’S IT! KEEP GOING, FUCK ME LIKE YOU WANNA RUIN MHEEEEE!!! AHHHN, YEAH, SO GOOD!!! IT FEELS AS IF YOU’RE GONNA TURN ME INSIDE OUT, BUT IT FEELS SO AMAZINGLY GOOOD!!! AHH, DO IT! FUCK ME! FUCK ME HARRRD! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME! FUCK ME!!” Mina demanded, sounding almost as if she were chanting a mantra. All the while, she rocked her body back against his thrusts, driving his dick as deep as it would go!

 

“Ahhhh, Mina…” Izuku groaned as he leaned over her, pressing his chest against her back and reaching around to grab her big tits and squeezing them hard.

 

“HWEEEEEEEEEE!!! YEAH! HARDER! I WANT IT ROUGH! AHHH, THAT’S IIIIT!! CUMMING!!! I’M CUMMING FROM YOUR BIG FAT BITCH BREAKER SPREADING MY HOOOOOOLE!!!!” Mina screamed, her pussy gushing hard now.

 

“Heh, she’s a screamer!” Izuku heard Rumi chuckle. “Honestly, it’s cute.”

 

“Momo’s been trying to bring her in for a while now.” Setsuna said, then moaned softly, “Nmmmmh, stick your tongue in deeper… Ahhhh…”

 

Their little exchange drew his attention, and he turned his head to see the two naked women sitting at the edge of the huge bed. Setsuna leaned back against the wall that the bed was flush against, her legs spread wide as Rumi knelt in front of her like she was giving her a dogeza bow, only her head was between the other girl’s legs, face pressed against her crotch! Izuku could see Rumi moving her tongue in long, broad strokes, then moving to suck on Setsuna’s clit, making her moan a little louder!

 

Izuku groaned, feeling as if someone had injected his dick with liquid steel at the sight! He squeezed Mina’s tits even harder, red lines of energy spreading across his skin like cracks.

 

“Oh, here we go!” Setsuna said just as the arcs of green electricity began sparking around him, “If he did that to Ibara, she’d likely go into a coma!”

 

Groaning, Izuku began slamming into Mina even harder and faster with One for All’s power flowing through him.

 

“AHHHHEEEEEEEEEEE!!! YEAH!!! MORE, POUND MY HOLE MORE, OH FUCK I’M CUMMING!!! MY PUSSY IS CUMMING SO HARD MY MIND IS GOING BLANK!!! FUCK ME MORE! FUCK ME MORE! FUCK ME MORE! CHURN UP MY INSIDES AND REARRANGE THEM INTO A SLOPPY MEEESSSSSS!!!” screamed Mina as she arched her back, letting out a long, deep moan as Izuku groaned in pleasure.

 

“NMMMMMMH, FUCK, DON’T YOU DARE HOLD BACK ON ME! GO PLUS ULTRA IN MY CUUUUUNT!!! CUMMING! CUMMING AGAAAAIN!!! AHH, YOU’RE FUCKING ME SO MUCH BETTER THAN THAT FIRST TIIIIIIME!!!” Mina wailed. “CUMMING CUMMING CUMMING, I’M GUUUMMMINGH!!!” she moaned, her voice slurring as she became drunk with pleasure.

 

Izuku could feel her pussy clamping down on him with her every orgasm, almost like it was trying to milk his dick! He leaned his head over her shoulder, swirling tongue with Mina as she let out more long, incoherent moans until he jammed his entire cock inside her and came, HARD!

 

“Shoooo, phuuulll…” Mina slurred, still tongue locked with Izuku as he groaned and stood up on his knees. Mina fell forward, sliding off his dick with a squishy wet sound. Her ass sticking up in the air, quivering, his cum only slowly leaking out of her as her cervix shut tight once his cock was out.

 

Rumi and Setsuna came at him together next. He locked lips with Setsuna, the two of them thoroughly exploring the other’s mouth with their tongues while Rumi gobbled his cock! She surprisingly managed to throat his entire length with seemingly no difficulty. He felt more than seeing her moving her head back and forth, her plump lips making lewd slurpy noises every time her face pulled back.

 

Izuku kept his arms around Setsuna’s waist, holding her close until she broke the kiss and moved to gently bite his neck. He hissed and groaned in pleasure, tilting his head to give her full access. She nibbled his neck with her shark-like teeth while her hand fondled his huge balls!

 

When they shifted positions, Izuku found himself on his back again, Rumi riding his cock in a reverse cowgirl while Setsuna straddled his face! The green haired girl leaned forward, fondling Rumi’s huge tits from behind while Izuku moved his tongue all around his girlfriend’s pussy.

 

“AHHH YES!!! SO, FUCKING, BHIIIIIIG!!! AHHH, I DON’T WANNA HOLD IT IN!!! AHHH, FUCK ME, POUND THAT BIG DICK UP INTO ME LIKE YOU WANNA BREED ME!!!! AHHH, I WANNA BREED, I WANNA BREED, I WANNA BREED, I WANNA BREED, I WANNA BREEEEED!!!” moaned Rumi, bouncing herself up and down on his dick, her shapely ass jiggling every time she brought it down on his cock!

 

Izuku grunted and groaned, pumping his hips up and down with her, his hands on Setsuna’s thighs, pulling her ass down on his face harder. The green haired girl moaned, and he heard a sickening wet tearing sound that he knew now as her using her quirk to split part of herself off. He later learned Setsuna had separated her upper body from the lower half and floated it around in front of Rumi. The two of them kissed hard, dueling tongues with wild and raw lust.

 

Everything seemed to blur, and Izuku found himself standing, Rumi pressed up against the wall, him holding one of her legs high in the air as he drilled his dick into her from behind. Meanwhile, Setsuna kneeled between them, licking his balls all over!

 

“AAAAAHHHGH, GYESH, BWEED DA BUNNY!!!” Rumi slurred while they dueled tongues, “SHO GUUD, GUUMMINGH!! AHH, BWEEDING ISH DA BESSSSHT!!!” she moaned as he began slamming into her using One for All again. Rumi let out a loud squeaking moan like an animal as Izuku pounded his length into her with a loud SMACK SMACK SMACK SMACK!

 

Time blurred again, and he was on top of Setsuna now, Rumi laying with the other girls, her pussy gaping so wide he could see all the way inside her. She looked up at him as she kept her legs wrapped tightly around his waist, locking him inside her as he thrusted again and again!

 

They kissed, and he heard her moaning into his mouth as they moved together on the now soaking wet mattress. He moved slower now, feeling the fatigue from using One for All like this, but still thoroughly enjoying being inside her. Setsuna seemed to pick up on this, and didn’t demand rougher treatment like Mina and Rumi had.

 

She hugged him tight, dragging her nails across his back, leaving long scratches there as he made her cum once, twice, five times before everything finally fell still! Izuku rolled off of her, not wanting his dense weight to smoother her. Unwilling to be separated, Setsuna moved to get on top of him, keeping his dick deep inside herself as she rested her arms on his chest and grinned sharply down at him.

 

“Happy birthday, Dekun.” she said, her tone oddly romantic in spite of the erotic setting. She then kissed him with a passion that rivaled Momo and Ochaco, reigniting his erection!
