Midoriya’s

In another life, the Midoriyas, Inko and her son Izuku, were timid creatures. They were shy, anxious and polite to a fault. A society of Quirks and Heroes was dominated by the confident and bold, traits that didn't come naturally to the teary-eyed family, leaving many barriers in their way to find their place in the world.

But this world is another matter. Here the Midoriyas are very comfortable with themselves and shockingly open with each other.

And with their sexuality.

"Mom! Are you sure I can't help you finish up in there?

"I'm almost done, honey," Inko called out from the kitchen. She was drying off the last dishes after sending her son to the living room to relax after dinner.

"It's almost time for Midnight's show and I don't want you miss any of it!"

Inko smiled and shook her head as she put the last dish away and dried her hands on her apron. Finished with the chore, she untied the frilly, yellow thing and tossed it towards the laundry room, vowing to deal with it later.

"Don't worry, I made it," she said as she plopped down on the couch next to her son.

"Just in time!" he cheered as he pressed the buttons on the remote to tune into Midnight's livestream on TV. His eyes lit up as the pre-stream clock counted down and leaned back into the plush cushions of their sofa, getting comfortable for the show ahead.

"You look like you're all ready to go, Izu," Inko commented on his appearance with no small amount of amusement.

Izuku rolled her eyes at her before gifting her with a bright smile. He was ready after all; he sat there, a towel underneath him to protect the couch.

And he was completely naked.

"Sure am, Mom. You better hurry up, too!"

Inko nodded as she started unbuttoning her sweater, and after she sat it aside she wasted no time in lifting her blouse off her plump body, too. She reached around to unhook her bra, but she still had trouble with the finicky clasp on this new one that Mitsuki had given her.

"Izu," she began to ask as she turned her back to him. "Can you help me with this?"

A chipper "Mmm-hm!" was all the affirmative she received before her son's strong, calloused fingers brushed against the soft, flabby roll of fat that hung over the snug band of her bra. In an effortless flick of his fingers, well-trained in helping his mother disrobe from her undergarments, the hook was released, and so were her breasts.

Inko sighed, relieved to be free of the restrictive thing. She pulled the bra's straps over her shoulders then tossed it onto the growing pile of her discarded clothes. When the enormous cups of the garment were removed, her heavy, saggy tits fell free, dragged down by gravity until they slapped against her chest.

Her breasts were large, as was her whole body. She had always been blessed with a generous chest, but as she let her body fill out into the chubby state she was in now, her breasts continued to grow. While shallow people still existed even in their Quirked society, turning their nose at the sight of a chubby women, Inko always puffed out her chest with pride, gifting the more open-minded gawkers around town with the sight of her big, bouncing melons.

Inko finished undressing, pulling her skirt and panties off in one smooth motion before kicking them away. Then she wiggled in her seat on the couch, getting re-situated and comfortable as she joined Izuku in waiting for the show to start.

"Better?" Izuku asked, a smile on his lips.

"Much," she replied with a deep sigh. She rested her legs on the coffee table in front of them, letting them spread open comfortably. She slouched in her seat a bit, letting her shoulders sink against the backrest, much as her son did. She patted her big belly that stood bunched up in front of her, enjoying the deep, satisfying "thunk" it made. Then she reached lower and patted the thick mound above her pussy, perking up a bit at the touch, before idly running her chubby fingers through the thick, damp swath of hair that sprouted from there.

"Come on, Midnight, let's get this show on the road!"

As if answering Inko's impatient demand, the timer hit zero and the screen shifted to show the R18 Heroine greeting her audience.

Mother and son both locked their eyes on the television as the scandalous heroine introduced the show. They were both big fans of Midnight; she was an amazing hero, a caring teacher, and most of all she took her responsibilities as the pre-eminent lewd hero in Japan seriously.

While by day she narrowly skirted the lines of acceptable, public behavior, this late night show of hers was her way to connect with the naughtier side of society.

She was a pornographic livestreamer, but one whose efforts were sanctioned by the Hero Commission. She had no need to hold anything back to entice patrons to pay up.

She was free to give her viewers an unrestrained, uncensored show.

And boy did she.

With her introductions done, Midnight wasted no more time getting into it. She spread her legs and started teasing her pussy, one experienced and well-used but still impossibly tight and enticing.

Inko and Izuku's eyes started to shine as they gawked at the lewd performance, and as Midnight started to moan while she masturbated, the pair joined in.

Izuku bit his lower lip to try to contain the giddy rattle in his bones that the shameless display triggered. His cock had grown long, swollen and tall above his waist and one hand instinctively started stroking it. This first couple of tugs were just to warm up, but by the third he pulled just a little firmer, teasing his flesh in a thrilling way before ramping up the rhythm to push his pleasure further.

Inko, too, openly started playing with herself. One hand pulled at her belly fat so her other could reach the wet folds of her pussy, but once her fingers were teasing her clit her forearm kept her flabby core contained. She moaned as her senses came to life, teased by watching Midnight's sinful actions on screen and taken farther as she manipulated her lust.

She was revved up but it wasn't enough; a tension, a hunger for more buzzed inside of her. Her free hand flexed, looking for some way to further satisfy the primal urges screaming inside her.

She fondled one of her breasts, pinching and pulling harder and harder, trying to feel more. It wasn't enough, but as she watched Midnight shove bigger and bigger toys into her hungry cunt, Inko pawed at her own pussy more and more furiously. She released her tit and bit a finger on her newly-freed hand, breathing heavier, chasing more and more sensation.

Still, she was more frustrated than satisfied. She pulled her free hand away and slammed it on the couch in the meager space between her and her son.

Inko glanced at Izuku, seeing him similarly vexed. His fist was blurring up and down along his cock, and his teeth were grit and his hips were leaning forward, hopelessly reaching for the satisfaction he craved.

He, too, slammed a frustrated fist against the couch, brushing his hand against hers. Surprised, he turned his head just enough to face her, never neglecting the rubdown of his manhood.

"M-mom?"

Inko didn't answer, only smiling at him. She patted his hand gently, prompting him to open his fist. Then she turned his hand and wove their fingers together before offering him a reassuring squeeze.

Inko and Izuku were very different; very open. They didn't hide their lust from each other; they acknowledged it, accepted it, and supported each other in it. Other families bonded over TV shows, too, and in their minds masturbating together to porn they both enjoyed seemed just as natural.

They were both endlessly horny, and right now they were similarly frustrated. But they were there for each other and it helped both of them to know they weren't alone.

"Oooh--OH!" Midnight's outburst on the screen pulled their attention back to the show, and they both got excited at the messy smile on the heroine's face. "I'm almost there, lovelies...Get ready because I'm about to..." her body twitched. "CUMMM!"

Midnight pulled a vibrator out of her cunt and her legs started spasming. Her eyes rolled up and her tongue hung out.

And Inko and Izuku were pulled back in. They fapped harder and harder, their chase to satisfy their lust closing in.

Then Midnight's promise followed through; her orgasm peeked with a powerful squirt blasting against the camera, leaving the screen a blurry, wet haze.

But it was enough for the Midoriyas. They joined Midnight in reaching their own climaxes.

Izuku groaned and let go; his cock erupted and spewed thick, hot cum back at him. He tilted his head just in time to avoid an eyeful of his own semen, but cum was splattered on his cheek and chest in a filthy trail along his body.

Inko's orgasm wasn't as messy, but it was just as intense. Her whole body shivered as the wave of lust coursed through her. Her legs shook and her shoulders heaved and her feet kicked the pile of clothes off the table.

A moment later her heart was pounding but she thought it was done.

She was wrong.

A squeeky sound leaked out from her loins, rumbling and growing louder. A queef escaped from her pussy, putting a cap on her orgasm.

"I fucking love this show," she said in a tired tone. Izuku could only nod in agreement.

The two sat there a few moments to recover. Midnight was faster on the rebound and the show would go on, but they were done with it for now. They would come back and watch the rest on repeat later, but for now they had their fill.

As they stood off the couch Inko shook her head.

"Tsk, tsk, Izuku. You make an even bigger mess beating your meat than the mess you make eating Katsudon."

Izuku blushed, embarrassed. Inko was teasing him but it was cute how he couldn't disagree. She reached over and wiped the glob of cum off his cheek, cleaning him up as she had since he was a child. She forgot to bring a new box of tissues out, and settled for bending over and wiping her son's seed off on her discarded clothes.

'They need to be washed, anyway,' she reasoned.

Still, cleaning her son's face didn't get them very far. They needed to shower.

"Come on, Izu, let's go."

He followed her to the bathroom. She turned on the faucet and let it warm up, then stepped in and waved him in to join her.

This, too, was nothing unusual for them. They had always bathed together. Izuku didn't hesitate to step in behind her and they both danced around each other to share the shower spray.

Both Midoriyas were very attractive specimens, naked and wet under the shower. Izuku's chest and abs looked as if they had been sculpted out of marble, and Inko's butt was large, wide and soft, full of jiggly fat reaching out from her hips that the shower's rain loved to crash against.

Any couple wouldn't be able to keep their hands off of each other, sharing a shower like this. And in literal terms it was the same for them; the two quickly went to work soaping up and scrubbing the other as they cleaned up. But to them there was nothing especially salacious about it; it was just normal for them to be naked together, to put their hands on the other's naked body.

Izuku stood behind his mother and scrubbed her back then they traded places so she could return the favor. Then they faced each other, Inko's bulging belly pressing gently against his abs, and after squirting some shampoo into her palms she started washing his hair.

Meanwhile, Izuku washed his mom's massive tits, no small task. He massaged the heavy, stretched out things, then lifted them up to scrub the sweat and dirt away from underneath.

Groping his mother's tits would seem wild to anyone else, but he was just happy to help her.

The moment between them was peaceful; they smiled and hummed and didn't put much thought into it.

Then Inko blinked and her hands stopped running through her son's hair.

"Mom?" Izuku asked, curious as to why she stopped. He was met with a playful smirk and a moment later he returned it, realizing what it meant.

"Oh, are you going to...?"

Inko nodded. "Are you ready?"

Izuku giggled. A childlike excitement came over him and he nodded.

"I'm always ready, Mom!"

"Okay, here it comes..."

She started massaging the shampoo into his scalp again, but Izuku's hands were bunched under his chin, unable to contain his glee.

Then he got his reward; Inko's loins let loose and started peeing.

On Izuku.

Her stream was unguided and uncontrolled, standing up as she was with her hands busy lathering her son's hair. Izuku squealed as her hot piss pelted his body, hitting the bottom of his stomach then reaching almost up to his navel for an instant before settling to raining against his crotch.

Izuku loved it! Mom peeing on him in the shower was nothing new; it washed right off but it tickled him so much! It was so hot, and the pressure was unpredictable. It was filthy and deviant, but none of that mattered to him. To Izuku it was simply fun; goofy, ticklish antics to add a bit of playful spice to their shower.

But getting peed on was only half the fun. After a moment of enjoying her gift to him, Izuku returned the favor, letting loose and peeing on her.

His stream was even stronger and it sent his cock flopping around like a fire hose. Its course was even wilder, creeping up her thigh, then flushing into her thick, green bush. Then it shot up to her belly, splashing the flabby folds of her gut, filling her deep belly button. Unlike hers, his stream never settled in one spot and Inko's midsection was treated to a dance of urine pelting her.

They both giggled until they were done, and after basking in the filthy warmth, they let the clean shower rinse their filth away. They finished cleaning each other up, dried off and dressed for bed.

To the outside world their evening would have been the peak of degeneracy. To them it was a ho-hum Sunday night.

After Mitsuki got word of her best friend's frustration with her new bra, the loud woman insisted on gifting Inko another that perfectly fit her body and her tastes. She sent over a catalog of designer lingerie that her connections in the fashion industry made available, and told Inko to take some detailed measurements so it fit just right.

While Inko was no stranger to altering Izuku's clothes, she couldn't easily measure herself. So after explaining the process to her son, she asked him to help her out.

"I've got it, Mom," he assured her, spinning the rolled-up tape measure around his finger. "Go ahead and get ready and we'll get this done!"

Inko lovingly patted his cheek; Izuku was always so sweet. She was proud of him for many things but his eagerness to help filled her heart the most.

Inko stripped down in front of him, neatly folding her clothes and resting them on the dining table. Izuku had brought her mirror out from her bedroom so he could see as he measured her, and guided her to stand in front of it.

She spread her arms out and Izuku went to work. He measured up and down her arm, around her hips, her belly, her legs. Inko gasped when he pressed his body against her from behind, his thighs smashing against her thick ass. But it wasn't from the close, intimate touch; instead it was from him wrapping the tape her breasts, the cool material of the tape sending a chill through her sensitive nipples.

After a few moments it was done and Izuku had noted her measurements.

"All done, Mom!"

"Thank you, Izu! You're such a big help." Inko kissed him on the forehead and Izuku smiled back. She sat down and started flipping through the catalog.

Completely naked; she had yet to get dressed.

"Can I help, Mom?"

Inko lit up and gave him a smile. Instead of pulling another chair beside her, she scooted a bit on her own, leaving just one of her large cheeks barely resting on the seat.

Izuku smiled at the invitation to join her in her chair. It would be a tight fit; his mother was not a slender woman, but they could make it work if they weren't shy and pressed close to each other.

'We may be many things, but Midoriyas are anything but shy!'

Izuku sat down. Their balance was a little awkward, but he wrapped an arm around her, resting his hand just under her naked, damp armpit on the opposite side. Inko also held him close, but by his fully-clothed shoulder.

Together they flipped through the catalog. They pointed at designs that caught their eye, laughing at a few of the more outrageous ones, and turning their noses at ones that looked hideous.

"What do you think of this one, Izu?"

"Hmm," Izuku considered her choice. It looked cute enough, but he wondered how it would fit on his mom. Even with a tailored fit, the bra looked like it was designed to press her tits together, to accentuate her cleavage.

"I'm not sure," he admitted, turning his head to study her closely. He stood up and guided her to turn to face him. After a moment of deliberating he reached out to grab her tits directly.

Inko didn't bat an eye, smiling mildly the whole time. Why would she? It was perfectly natural.

He started by cupping her heavy tits in his hands. His palms were wholly inadequate to contain the massive forms; the soft, meaty flesh spilled over his fingers. He bounced them in his hold a few times, twisting his face into an unsure grimace.

Then he grasped her tits from the sides and smashed them together, staring at them a moment before letting them drop.

"I don't know, Mom," he began. "You'd look great with that holding them tight, but I think something that lets them sink in and breathe would be even better."

Inko looked down and repeated Izuku's test, squeezing her tits together then letting them drop.

"I think you're right, honey. Let's keep looking."

They looked some more until Izuku gasped in delight.

"This one, Mom! It's gotta be this!" Inko followed his finger to study his choice then blushed.

It was pretty cute, she had to admit. It was pale yellow, with some interesting, lacy designs that weren't too flashy. It was for the most part right up her alley.

"You could get these to go with it, too!"

Inko followed his finger further down the page until she saw the matching item in question.

"A thong, Izu?"

He nodded.

"Definitely! Your butt is really cute, Mom, you should flaunt it!"

Inko thought about it a moment then stood up and walked back to the mirror. She turned her body and looked at her ass in the reflection. She reached back and smacked it a couple times, letting it jiggle. Then she shook it a few times, too.

"Ah, what the hell. If I've got it, might as well show it off!"

"Definitely!"

One evening Izuku was kneeling at the coffee table, finishing his homework as he listened in the background to the day's hero news on TV. UA's course load was advanced, but for a lifelong hero nerd like him, it was no big deal.

"Done!" Izuku announced to the empty room, slamming his textbook closed and reaching out to stretch.

"Oh, perfect timing!" Inko walked through the door just then, setting down some shopping bags on the counter before bringing one of them over to her son.

"I picked these up for you when I was out," she said, offering the bag to Izuku.

Izuku thanked her and tore into the bag, pulling out three books.

"Whoa, I almost forgot!"

Inko giggled.

"You're lucky I'm never so scatterbrained to forget when the new porn comes out!"

Izuku was excited! The first book was Mount Lady's debut adult gravure album. He flipped through and smiled at the shots of the Mineyama Heroine in different sexy cosplays, both at normal size and giant size.

'I wish I could've been there when she did this one!' he thought when his eyes lingered on a pinup of Mt Lady spreading her pussy in front of the windows at the Tokyo Skytree, giving the crowd of tourists a show of a lifetime.

The next book was an anthology of hentai centered on assholes. His mother was the real fan of anal action, rimjobs especially, but Izuku would get plenty of mileage out of this, too. He was lucky that he and his mom shared so many of the same tastes when it came to smut.

But as much as those first two books excited him, his eyes began to sparkle as he looked at the last one.

"Whoa! I can't believe you got this, Mom!"

It was the latest doujin release from his and Inko's favorite circle. The pair of them had worn out the previous release, a ridiculously wild story about Uwabami's snakes going rogue and relentlessly fucking her in a masterpiece of tentacle bondage action. They'd spilled gallons of lust over that last book, but Izuku could tell this one was going to steal more cum from them by far.

'In fact, it looks like it already has...'

Izuku noticed how half the book was crinkled and warped, like it had suffered some water damage. He furrowed his brow, touched the still damp pages before he brought it close to his nose for a curious sniff.

'Yep,' Izuku thought as a wave of recognition flowed over him. He turned to his mother and gave her a knowing smile, one that she responded to with a blush.

"Couldn't wait to get home and check it out, huh?" She shook her head.

"Did you just start fapping to it right there in the bookstore?" She nodded. "You're lucky nobody saw you!"

Inko's blushed deepened and her hands anxiously started gripping her skirt.

"Well..." she started. "Who says no one did?"

Izuku's eyes went wide. "Mom!"

"Don't worry," she assured him. "Those nice boys won't tell anyone...not after I let them jerk off and cum on me while I masturbated reading the book."

"Holy shit," Izuku marvelled. "That sounds pretty exciting!"

"Eh, not really. They were cute and all but a few pumps and they were done." Inko sighed, clearly unsatisfied from her spectators' performance. "This was far more exciting," she said, tapping on the cover of the doujin.

Izuku opened it up and started skimming the art, page-by-page. This one focused on Miruko, and instead of a heroine being a victim to her own quirk, the story was about Miruko taking charge and fucking anyone in sight with an impressively long, carrot-shaped strap-on.

"Fuck..." Izuku whispered in awe, one hand absentmindedly reaching into his lap. "I can see what you mean..."

Izuku soon got to a page that had clearly been Inko's favorite. Her love juices had stained the paper, right over the image of Miruko furiously fucking a woman's big butt, at the same time she was pulling a guy towards her by his cock so her long tongue could reach out to slurp up his asshole.

"Mmm," Inko said, salivating as she looked on with him over his shoulder. "I'd love for Miruko to fuck me like that," she purred.

Izuku didn't hear her. He was lost in the pages of the perverse book, his cock pulled from his shorts and in his firm, furious grasp. Izuku flipped back to the first page, carefully taking in every twisted detail, grunting and sweating as he stared in primal fascination.

Inko smiled lovingly and kissed the top of her son's head. She watched him a moment as she slid his hand along his big cock. It was much bigger, much more impressive than those gangly boys at the bookstore. They couldn't even tear her interest away from some printed smut, but if they had been packing the kind of heat her son had between his legs it would have been a different story...

Inko froze for a moment as a strange tingle ticked her inside. She didn't know where it came from but for some reason she started to feel excited again herself.

'Well, Izuku's having his fun right now so I think I'll do the same.' Inko turned and started rubbing one of her breasts through her shirt as she walked to her room, where there was a box of dildos waiting with her name on it.

The anal action in that Miruko doujin, all the images of the Rabbit Heroine pegging butts, plump and small, would not leave Inko's head, even days later. She wanted to feel something up her ass, something wild and powerful!

Which was an issue for her. She was fat enough that reaching around to manipulate a toy behind her like that didn't work. She would sometimes mount a toy on a chair and fuck it that way, and with the heavy weight she could drop on it she could feel a bit of a thrill stabbing into her.

But it just wasn't enough. She wanted real power pushing into her; she wanted to be pummeled and dominated in her ass!

So she broke down and bought a fucking machine. The ad said it was ruthless and unforgiving; the company's logo was a demonic beast that even All Might would be intimidated by.

"I can't wait!" Inko squealed as she tore into the box. And in an instant that glee went cold.

"IZUUUU!"

In an instant her son, her little hero, rushed to her aid.

"Mom! Are you okay? Is everything alright?"

Inko turned to him and started crying, and he swept her up into a protective hug.

"What's wrong?!"

"This!" Inko pointed to the box and Izuku let her go to peer inside.

He calmed a bit, seeing that the problem wasn't a big deal to anyone but a horny mother.

"What's all this?" he asked.

"It's supposed to be my new fucking machine but there's a million pieces!" She fished out the thick instruction manual. "I don't know how to put this together! Help!"

Izuku smiled and took the book from her. It was cute that his mother got so worked up over something like this, but Izuku was always eager to help.

"Sure thing, Mom. Let me handle it!"

It seemed like hours but finally Izuku set the machine up. Inko had been impatient the whole time, and insatiable to boot. Izuku had suggested she masturbate while he worked on it, but even after all the screams and moans he heard in the background as he worked, nothing seemed to quell her lust.

"All done!"

"FINALLY!"

Inko wasted no time, stripping her clothes and kneeling on the bed. The machine was set up just off the foot of her bed and Izuku helped to guide her as she crawled back and shook her thick ass towards it.

"There we go, Mom. Right there!"

Inko leaned back against it, feeling the dildo on the machine's pistoning rod. She wanted to just slide onto it, let it pierce her asshole, but she kept missing the mark and it slid against her taint.

"A little help, Izu?"

"Okay," he replied, patient as ever. With one hand he held the dildo; it was thick and menacing, but no longer than his own cock. With his other hand he gripped his mother's plump ass, and pulling gently he guided her back and aimed the toy until it prodded against her hole. With a tap against her cheek, Inko leaned back again and the toy filled her anus with a wet squelch.

Inko cheered.

"Perfect! Now go...go go GO! Fuck meee!"

Izuku shook his head; his mom was such a slut. With one last pat against her butt he flipped the switch and turned the machine on.

It didn't have a dial for speed; the machine had one setting - CRAZY. The motor whirred to life and with a sharp, punching motion it pushed the toy cock into his mother, in and out. Izuku was surprised at how much force the machine had behind it; for a moment he was worried for his mother.

"Are...are you okay, Mom?"

Inko took a moment to reply, but when she finally did she started with a sigh.

"I'm fine, baby. Other than being unimpressed." Izuku's eyes went wide. "They made it sound like it would be something special but...feh."

"Feh?!"

"Oh well," Inko said, resigned to the limits of the machine. "It will have to do. Thanks for all your help, Izu! Sorry to waste your afternoon."

Izuku waved off her apology as he left her to her fun. Once he closed the door behind him, he stood there, frozen.

"That thing was crazy, but Mom barely even felt it!" He shivered a moment, and looked back at the door. What kind of monster was she?

His shivered lingered; something more stirred within him. He didn't know why, but all of a sudden he felt hot.

And bothered.

A few days later found Inko tidying up around the apartment. She was about to start on laundry and was gathering the dirty clothes.

All that was left was Izuku's room. Without knocking, as the two of them never did when entering each others' rooms, she walked in.

...right as her son was masturbating.

It wasn't a shock to her; the two of them were far too open and depraved for that. It wasn't all that surprising for her, either. She didn't want to distract him, especially since he seemed really into it, so she stood in the doorway and watched.

Izuku was laying on his bed, completely naked, his sheets damp from the sheen of sweat wicking off his body. He held his phone close to his face, staring at something glowing off its screen. His other hand was, obviously, on his cock, desperately churning up and down.

His head and shoulders dug into his pillow underneath him, and his toes pushed off the bed, too. He was lifting his hips high above, reaching his long, heated penis as he leaned into his desire, into his lust, into the aching want his cock had to fill something.

Or someone.

'He's close,' Inko noted, staring intently at the scene before her. And just as she thought, a moment later Izuku exploded, cum flying above him before crashing back down on his body and on the bed.

Izuku's body froze in that awkward bridge a moment until the high of his orgasm passed and he collapsed tiredly onto his mattress. His eyes were dazed and his chest heaved as she fought to catch his breath.

Then finally he did and he let his head roll to the side.

"Oh! Mom! I didn't know you were there!"

"Mm-hmm," she replied, taking his acknowledgement to enter. She gathered his dirty clothes, including the ones he shed before stripping down for his playtime. She crinkled her nose at the mess on his sheets; she was glad her son had a good time with himself but now she'd have to clean those, too.

"Was it that good, Izu?" she asked.

"Definitely," he said, his voice heavy with confidence and satisfaction.

"Oh?" His tone piqued her interest and she sat her hamper down and walked beside him as he sat up on his bed. "What were you jerking it too?"

"You remember my friend Uraraka, right?" Izuku turned the phone so she could see a photo of the girl in her hero costume. Inko nodded at the the girl's image smiling at the camera.

"Well, we were in Heroics today, suited up and everything. At some point, Uraraka bent down to pick something up and the back of her suit ripped! Guess she had been too rough on it lately and it gave."

"Aww, bless her heart," Inko said, feeling sorry for the girl.

"That's not all! Turns out she's been going commando underneath, so when it ripped her ass was on full display!"

"Oh no! She must have been so embarrassed!"

"Yeah, she was. But Mr. Aizawa let me follow her back to campus to get changed, so I could block anyone from seeing."

"That's so wonderful of you, Izu."

Izuku smiled; hearing his mom praise him always filled him with warmth. Then his smile turned mischievous as he swiped the screen to show his mother the next photo.

"The best part is that we had body cameras on for the exercise. So, while no one else got to see, I was able to record Uraraka's bare ass, bouncing and jiggling with every step, the whole walk back to school!"

"Izuku Midoriya!" Inko swatted her son's shoulder. Certainly, Inko was charmed by the first few seconds of the clip she saw; the girl certainly had a cute ass, one any boy and his mother would love to taste. But still, it was scandalous what Izuku had done!

"We may be really open about things, but that doesn't mean everyone else is! You can't just record that poor girl like that without her permission!"

"Oh, don't worry. I did have her permission."

"Y-you did?"

Izuku nodded. "Yeah! Actually, she insisted. She stopped me from turning the camera off and said she wanted to make sure we had something to remember it by. She was really excited to show off!"

Inko blinked. Uraraka...wanted to be exposed? To her son, no less? That changed things.

"That girl sounds pretty special, Izuku." He blushed and Inko seized the moment. "Just how special is she...?"

"Well," he said, before gesturing to the mess on his bed. "Does all this answer your question?"

"Hmm," Inko purred, imagining the possibilities. "If she's that open to our perverted ways, maybe you should invite her over some time. Take things to the next level with her."

"We already made plans for Summer Break! It'll be all-fucking, all the time!"

Inko giggled. "I can't wait to meet her," she said.

"Oh, she's going to love you, Mom." Izuku wagged his eyebrows suggestively. "I guarantee it."

That sent a shiver down her spine. The girl was really cute; the possibility of fucking his son's little girlfriend excited her!

"Can I see the whole video?" she asked. Izuku smiled and sat on his knees, inviting Inko to join him on the bed. He sat it phone down flat between them and pressed play.

It didn't take long for Inko to be charmed by Uraraka's ass. It was big and soft; Inko was proud of her own plump dump truck, and she got turned on by this girl's butt, too. She shimmied out of her skirt and started teasing her pussy as she watched, and Izuku, already recovered from his earlier climax, started jerking along, too.

The girl hadn't just walked the whole way; she teased her cameraman, swaying her hips and reaching back to spread her cheeks now and then. The dirty talk she teased her son with got Inko salivating, too.

'I like this girl,' she thought as her fingering grew more feverish, as she lost herself to her lust.

The video was almost over; Uraraka was walking up the stairs to the main campus. Before she opened the door to enter, she stopped and turned back to flash the Izuku holding the camera a naughty smirk. A moment later the camera tilted down and focused on the girl's ass. Again Uraraka's hand reached back to spread her cheeks and reveal her cute little asshole. But this time something else happened.

PFFRRRTT

The girl farted, giggling the whole time as she spewed some undoubtedly foul air from her chubby ass. It wasn't so much Inko's thing, farting; she didn't get turned on by it. But the close-up view, the way her tight little asshole rumbled and flared open as she farted...Inko liked that.

A lot.

"CUMMING!"

"AAAAHH!"

Together, the mother and son reached their moment and let loose. Izuku spewed rope after rope of cum; so much that no one would have known he had just wrung himself dry a scant few minutes before.

Inko's release was just as messy, squirting a powerful burst of lust that added to the mess on the bed.

But not just the bed. Their love juices rained on Izuku's phone screen, staining it with globs of lust and filth.

Inko picked it up, and noticed that final frame was Uraraka, facing the camera once again and posing with a cheeky smile on her face.

'She sure looks cute like this,' Inko thought. She sure looked cute with cum overlaid on her in a tribute to the Midoriyas' shared love for her.

Summer break arrived. Ochaco would be coming over next weekend, after spending some time back home to visit her parents. Izuku and Inko were excited; the girl had been just as eager to meet and fuck Izuku's mother as she was to sleep with him. They were all looking forward to it!

But today was special, too. It was Inko's birthday! Izuku got the cake, put up some decorations, and had spent the morning pampering his mother.

And now that lunch was over, she had just opened the present he got her.

"Oh, Izu, this looks nice!"

"Do you want to try it out?"

"Yes!"

The pair scampered to her bedroom. Izuku unboxed the present as Inko started shedding her clothes.

"I think you're really going to like this, Mom," Izuku said, excited to see her try it out.

It was a new dildo. His mother wasn't hurting for sex toys; the overflowing box in the corner was evidence enough of that. But after seeing her disappointment with the fucking machine, Izuku wanted to find a toy that would satisfy Inko's voracious appetite.

'I couldn't find any, though,' he remembered. So he had to go a little "Plus Ultra" and have one made, just for her.

He enlisted Mei Hatsume's help, as well as All Might's. Midnight even joined in to offer some ideas, too.

They molded the toy after the Symbol of Peace's monstrous cock. The girls were skeptical that Izuku's mother would be able to handle it; Midnight quipped that no human woman would! But Izuku waved off their worries; after seeing how unaffected she was by that demonic sex machine, he was certain his mother could take anything up her ass that they could throw at it.

Mei crammed the thing full of all kinds of tech; motors and vibration and any number of thrilling feedback functions. Normally Izuku would be concerned; Mei often got carried away and overpowered her babies. But that was just why he went to her; Izuku wanted something that got carried away!

And now he was about to see the fruit of his efforts. He sat the toy on the floor and Inko had to stand on her tiptoes for her hips to clear the monstrously tall thing. Izuku smiled when he saw her bite her lip, when he heard the squeals of excitement and anticipation as she loomed over it.

Then she dropped. She let her knees bend and in one fell swoop she slammed her big ass over the toy, letting it plunge inside of her, all the way to the hilt.

"O-OHH!"

Inko felt electrified the instant this thing filled her. It was so big, so long; it felt like it was tickling her ribs! Even without moving it was rearranging her insides in the most intense way.

"Does it feel good, Mom?"

"It feels AMAZING, Izu!" The breathy tone in her words let Izuku know she spoke the truth.

"Get ready. It's going to get even better!"

Izuku reached between her legs, the back of his hand brushing Inko's thick. wet pubes. He pressed a button on the base of the toy then pulled back.

The toy came alive, rumbling and whirring. Inko's eyes crossed and her whole body started shaking; the vibrations were carrying through her whole body.

"F-fuuuuck!" she cried out, her voice warbling as her body was rattled.

Izuku watched as her tits shook, along with her belly fat. Her legs were kicking out, back and forth, and her toes were flexed, too.

Then the toy went quiet, just for a second, before whining loud.

"AHHH!" Something happened, something charged up and hit Inko just right and that was it.

She came, and she came HARD. Her hips rocked back, her arms scrambling behind her, scraping the carpet to pull her off of the dildo. And the instant it popped out of her pussy, Inko squirted, a powerful, high-pressure burst.

Then she lost all control and started peeing, a flood of piss rushing out. The flow was strong and spewed out in an high arc, but it still wasn't enough to clear that height of the All Might-sized dildo, standing tall and proud. Her piss splashed against it, running down its length until it soaked into her carpet.

"That good, huh, Mom?"

She shot back up into a sitting position and grabbed Izuku's shoulders.

"Fuck, Izu. It's the BEST! I LOVE IT! And I love you!" She pulled him forward and kissed him, planting a big, juicy kiss right on his lips.

When she pulled back, Izuku was blushing. Inko's eyes widened, surprised that she had kissed him so forcefully.

'Why did I do that?!'

Before either of them could process the kiss, the doorbell rang.

"Oh! She's here! Time for your other present, Mom!" Izuku hopped up and rushed to answer the door and the awkward kiss was forgotten.

Mitsuki stood in the breezeway after knocking on the door. She sighed as she waited for either Inko or Izuku to answer.

'Come on, Mitsuki,' she thought, trying to psych herself up. 'It's Inko's birthday; don't be a downer!"

Mitsuki loved Inko, as much as she loved her own family, if not more. Same with Izuku. He was her sweet, adorable nephew that she wished her own shithead son would take a cue from.

'Well, certain cues, anyway...'

Mitsuki loved the Midoriyas but they were exhausting. She was well aware of their deviant antics; the brazen nudity and uncontained sexuality that took place just on the other side of that door.

Mitsuki had been pretty wild in her day, and she certainly wasn't one to hold back her emotions now. Even so, her deceptively meek friend was in a whole other league. Mitsuki's quirk was like a fountain of youth, keeping her skin youthful and pristine, but even she couldn't hope to keep up with her fat little friend and her insane libido.

'To say nothing of little Izuku, too...'

The Midoriyas were very dear to her, but they were kind of a pain in the ass. They were always inviting her over for marathon sex and Mitsuki always found an excuse to escape their ravenous attention for her.

But today was Inko's birthday. And she dearly loved her friend, so she wouldn't refuse a visit for the birthday girl.

'Besides,' she thought, her face taking on a chagrined smirk. 'I'm the present!'

It was a tradition, for better or worse. Whenever one of the Midoriyas had a birthday, she was the present. She offered herself to be fucked by Inko for her birthday, letting her friend have her fill of her on her special day.

But no matter which one was having a special day, the other would join in, too. It wouldn't take long for both of the green-haired sex fiends to double-team her, to ravage her in tandem and overwhelm her.

Mitsuki sighed. She hoped she was ready for this.

The door swung open and a green blur rushed her and wrapped her up in a hug.

"Auntie!"

Mitsuki recovered from the sudden tackle; Izuku was already starting with too much energy!

'Still,' she thought, smiling and returning the hug. 'He is a sweet boy, despite it all.'

The hug was warm and calm, but only for a minute. The peaceful embrace ended with a jolt as Izuku pulled her into the apartment, shut the door and pinned Mitsuki against the wall.

Then he kissed her, deep and hot, his tongue wrestling hers in a moment of sudden passion.

Mitsuki tried to push back at him, to give herself some breathing room, but her resistance crumbled quickly as she melted into the kiss, leaning into his lips and enjoying the taste of her best friend's son.

As the kiss went on, he didn't let his hands stay idle. While one was planted against the wall right next to her head, his other hand roamed her body. He squeezed and kneaded her tits through her blouse, he lifted her shirt just enough to rub her toned abs underneath. Then, without the slightest hesitation, he sunk his hands under her skirt, under her lacy panties, and plunged his scarred fingers inside of her.

"Mmf!" she squeaked into the kiss. Izuku's lips pressed against hers were the only thing that muffled her cry of "oh, fuck!"

Izuku didn't take things slow. His fingers dug into her and drew her closer to him. In an instant she was soaking wet, and a moment later her legs were losing strength and her body began to twitch.

Mitsuki moaned into the kiss, louder and louder, then rested her hands on Izuku's shoulders for support. Sensing her frantic emotions, Izuku pulled away from the kiss and smiled.

"Fuck, Izu-kun. I'm...CUMMING!"

Sure enough she did. With his fingers still inside her pussy she reached her first climax, and Izuku cheered at the feel of her body tensing around him and the pressure of her squirting against him. When the moment passed he unplugged her, pulling his fingers out, and her lust was fully freed, staining her clothes and leaving them drenched between her legs.

Mitsuki was panting, still leaning on Izuku to keep her balance. She stared into his eyes; her face strained but Izuku looked back with a smug smile. She saw his hand come into view as he brought it close to his face, dripping with her love juices. Then one by one he popped his fingers into his mouth, savoring the taste of her naughty nectar.

"Mmm...you taste so good, Auntie."

Mitsuki had an image of being loud and brash. Most people thought she was a huge bitch, and she wore that badge with pride. But for all of her strength and abrasiveness, right now she was wrapped around this boy's finger. Seeing him in control of the situation, in control of her, seeing him enjoying her body so brazenly, Mitsuki couldn't help but blush.

"Mitsuki! So glad to see you!" Mitsuki blinked and managed to tear her gaze away from Izuku's magnetic stare. She looked at Inko and her eyes widened.

"Good, Izuku got you warmed up. Now we can get this party started! You can help me try out my new toy."

Izuku and Inko cheered together, but Mitsuki felt her heart sink. She thought she knew what she was getting into, another sex party with her best friend.

But that new toy, that present that could only have from her twisted son, was overwhelming the woman, held tightly in both of her arms. Huge and monstrous, already glazed in Inko's lust, it was an intimating sight.

'She wants to stick that inside of ME?'

Hours passed and the Midoriyas fucked Mitsuki silly. She laid on her back, soaking Inko's bedsheets as sweat poured from her body. Inko had utterly destroyed her holes with that giant dildo and her body kept producing more and more of her glycerin sweat in an attempt to keep the massive thing lubed up.

Finally Inko had set the toy aside; its batteries had run out and the birthday girl took that as an opportunity to shift gears.

Now Inko was sitting on Mitsuki's face, grinding her wet, hairy pussy into her face. Between her fat ass and her thick things, Inko was nearly smothering Mitsuki, but thankfully the woman was considerate enough to leave her enough slack so she could breathe easy.

...at least, she could have breathed easy if Izuku wasn't at the foot of the bed, fucking the breath out of her. Even after Inko's new toy stretched her holes out, Izuku's monster cock still stuffed her full. And he wasn't gentle about pounding into her.

'Maniacs!' Mitsuki screamed in her head.

Still, it wasn't like she hated them. On the contrary, she loved Inko. She loved hearing the woman moan as Mitsuki licked her sloppy pussy, as her nose tickled her forest green pubes, as she coaxed her clit to reveal itself so she could suck on it.

Even with Inko's flabby legs trapping her head, even through the pounding of her racing heartbeat, Mitsuki could hear her best friend moaning and laughing, enjoying her lustful affection in full measure.

'So cute..." Mitsuki thought. Inko was a handful, but her joy was music to her ears.

Still, they were too much for her. Soon they both came; Inko nearly drowned her by squirting right in her face and the massive load Izuku was pumping into her cunt left her feeling light-headed.

"I need...I need a break, okay?" Mitsuki barely got out, begging for them to give her a breather.

With disappointed looks on their faces, Inko and Izuku agreed and pulled away, letting Mitsuki rest in peace. If she hadn't been so exhausted she would have glared at them, but it was all she could do to stay conscious.

She tried to get her breathing under control, tried to muster up her strength for the inevitable next round. It had only been a moment before Inko started shaking her shoulder like a petulant child.

"That's enough rest, right? You're ready for more, right, Mitsi?"

Mitsuki closed her eyes and growled as her only response.

"Come on, Aunty, we want to fuck you some more!" Izuku joined in shaking her, and Mitsuki had it.

"ENOUGH!" She screamed, sitting straight up and hopping off the bed. Her tired body was screaming at her but she couldn't take it anymore.

"I've had it!" She continued as she spun around to face them. Sweat and cum alike were sliding down her naked body but she didn't care.

"Look, Inko, Izuku, I love you both but you two are fucking maniacs! I can't keep up with you. I don't know how anyone could!

"I don't know why you don't just fuck each other!"

With that, Mitsuki scooped up her clothes, not bothering to put them back on, and stormed out of the apartment.

Inko and Izuku sat there silent and wide-eyed, stunned at Mitsuki's outburst. After a moment they turned their heads to face each other as the woman's words sunk in.

'Fuck...Izuku?' Inko thought.

'Fuck...Mom?' Izuku ran the words through his head, too.

They both ran their eyes across each other's naked, sweaty bodies. It was hardly an unfamiliar sight to them, but for all their openness with each other's sexuality they had never considered having sex with each other.

Mother and son? Incest?

"That sounds like a GREAT IDEA!"

"Why have we never thought of this before?!"

They both smiled and got ready to make up for lost time.

Inko sunk back into her bed and Izuku wasted no time climbing on top of her. He leaned in for a deep kiss, but quickly shifted to licking her face. He was relentless, running his tongue all across her face; he reminded Inko of an excited puppy.

Once her face was slick with his saliva, Inko pushed him off and guided him to rest on his hands and knees. Inko crawled around him on the bed and licked her lips as she stared at the prize he was presenting to her.

His ass.

She leaned in and started licking his sweaty asshole. She smiled when she felt her son shiver underneath her touch, and her heart beat faster when she heard the girlish moans that escaped his lips.

'My cute little slut,' she thought as she continued to devour his ass. If this is how he reacted to getting rimmed, she decided she needed to buy a new strap-on so she could fuck his naughty ass, too.

As she continued to lick, nuzzling her chubby cheeks against his tight ass, one of her hands reached up to stroke his long cock dangling under his hips. It was hot and hard, aroused already by the rimjob, but there was always room for more.

Her pudgy fingers slid up and down the length of his rod, first slowly as they dragged along the taut skin, then faster and faster. Izuku's breathing and his moans grew more frantic until finally he couldn't take the sensations of his mother's hand on his cock or her tongue in his ass anymore.

"MOM!" he screamed as his body tensed and cum shot from his cock towards the bed below him.

At least, it would have hit the bed if Inko had not acted so quickly. She reached her other hand down, her palm cupped under his tip to collect the storm of cum he released. A lot of it still spilled and splashed out, but by the time he was done her hand was full.

Her empty hand released his cock and gently patted his ass, signaling him that he could rest for a moment. When he collapsed face first in the mattress, Inko raised her full hand to her lips and gulped down the handful of her son's seed.

"Mmm," she sounded. "So good..."

Seeing Izuku so tuckered out from sex, of all things, stirred some maternal instincts inside of Inko. She gently lifted his shoulders and moved him to rest his head in her lap. His hair, slick with sweat, tangled with her drenched, thick, matching pubes as his head settled comfortably in place.

"Poor baby," Inko teased. "Here, let mommy take care of you."

She didn't have to lean over much to drop her tits in his face. She could barely see his face over them, but she did peek a smile stretching across Izuku's cheeks.

Inko lifted one massive breast and guided her thick nipple to her son's lips. It only took one prod of the stiff nub against his lips for him to open up and accept it into his mouth.

Inko smiled at the warmth of her son sucking her nipple. His tongue flicked across it inside of his mouth, triggering goosebumps to form on her skin.

"Mmm, such a hungry boy," she said, her voice sultry and teasing. Izuku seemed to like the way she egged him on, if his hardening cock was any indication.

Inko decided to give his manhood some more attention. She reached over to take hold of it again, leaning down and pressing her chest against her son's face. The pressure of her soft breasts against his face was too much and before Inko could even pump a single stroke along his cock, Izuku exploded again and a new rain of cum went flying.

"Izuku! Shame on you! Spoiling my fun by being a quick shot." Izuku sat back up, stealing her nipple from Izuku's mouth and making a show of pouting.

Izuku played along and looked chagrined.

"Sorry, Mom. How can I make it up to you?"

Inko smiled a dangerous smile at him.

"I know one way..."

Inko mounted Izuku's face, just like she had Mitsuki's a little while ago. She sat down and grinded her pussy against his lips.

Izuku started licking away, enjoying the sweetness of his mother's cunt, but he was surprised that was what she wanted.

'Not that I'm complaining!'

"Mmm, that feels so good, sweetie. I can never get enough of this...' Inko sighed happily as her son ate her out.

"But this isn't all I want."

Izuku was confused; what did she mean by that?

Then he found out.

Inko relaxed her body and let loose. She started peeing, right into Izuku face.

"Ahhh..." she sighed again. She always enjoyed pissing so freely, and feeling it splash against her son's face underneath her was a whole new sensation.

Izuku coughed and sputtered, surprised by the sudden shower. But he quickly got used to it and laughed and sputtered as his mother's hot filth rained against him.

She went on and on but eventually she ran out. A queef squeaked out when she was lifting off of his face and when she laid down beside Izuku both of them started to laugh together.

Inko turned her head to face him, and Izuku turned his to meet her gaze. They stared at each other, each of their faces flushed from the excitement of taboo sex, before their gazes softened.

"I love you, Mom," Izuku said

"I love you, too."

Izuku mounted his mother again and slid his cock inside of her. Both of them felt a spark of new pleasure between them as they formed the lewd connection.

Izuku lifted her flabby legs under his arms and started thrusting his hips, digging his cock inside of her.

"Oh! Yes, Izuku...that feels so good!"

"YOU feel so good, Mom! How are you so tight?!"

Inko giggled. Sex had never felt like this before; not with Hisashi, not with any of her toys, not with the occasional stranger she coaxed into a quick tryst when she went out on errands.

Izuku let her legs fall and leaned down close against her, his hard abs pressing against her soft belly, his chiseled pecks smashing her fat tits. He stole his mother's lips in a deep kiss, his hips driving his cock into her harder and faster the whole time.

They pulled apart again, a trail of saliva between them, and they stared lovingly at each other for a moment.

"Izuku," Inko breathed.

"Why don't you get me pregnant?"

Izuku stopped moving, stunned by his mother's request. Was she serious?

The intensity of her stare showed that she was. Once the idea sunk in, Izuku could feel his member growing inside of her, their bond growing even tighter.

"Fuck yes, mom!"

Then he came, flooding her loins with his seed.

Izuku was about to pull out when Inko snared him with her quirk, pulling him in and holding him tight.

"If we're going to do this, we need to make sure it sticks. Get ready to fuck me over and over until there's a baby in my belly, Izu!"

Izuku smiled. Nothing sounded better than constantly fucking his mom.

Months passed and Mitsuki found herself at the Midoriyas' doorstep once again. She didn't remember what this "special occasion" was supposed to be, but it didn't really matter because she knew it was all just an excuse for another fuckfest.

The door opened and she stepped inside to be greeted by Izuku and Inko.

Both were naked, and Izuku's hand was firmly attached to his mother's fat ass.

Oh, and Inko was pregnant. Very pregnant.

Mitsuki shook her head, like she always did when she saw them. It should have been unthinkable to imagine Izuku getting his mother pregnant, but she knew what kind of deviants these two were.

'Still,' Mitsuki thought. 'They're starting to rub off on me. Inko has never looked hotter than she does right now with that big, bulging belly...'

"You look sexier every time I see you, girl," Mitsuki said, reaching over to pat Inko's swollen stomach. "Pregnancy suits you well."

Inko giggled and shared a glance with her son.

"We wanted to talk to you about that, Mitsi," she began, getting Mitsuki's attention. "Izu and I would like for the little one to have a friend to grow up with. A little brother or sister. So we were thinking..." She was interrupted as Izuku cut in.

"Why don't I get YOU pregnant, too, Auntie?!"

Mitsuki stared. She didn't think these two could surprise her anymore but here she was.

They were smiling eagerly, as if it were the most natural question in the world. Her best friend, and her best friend's son, who was the father of her best friend's unborn child, asking if he could knock her up, too?

By this point Mitsuki had given up. These two were insane, and that insanity had infected her, as well.

Mitsuki lifted her skirt and yanked down her panties, showing off her wet, hairy pussy to the pair.

"Sounds good to me. Get in here and get to work!"
