Midoriya's Daycare for Nice and Naughty Boys

by Mono_D_Duo, Pie555

Summary:

Midoriya Izuku runs a daycare for boys that helps prepare them for later schooling. He makes sure they learn their spellings, their arithmetic and the responsibilities of having quirks. The only really strange thing, one that is kept under utmost lock and key, is that he, and his two members of staff, uses the daycare as a means to get close to, earn the trust of and groom young boys.

A rebellious, wilful little boy, Bakugo Katsuki, is signed up for the daycare and his parents have signed the special permission form that allows the members of staff to use corporal punishment if he gets out of hand. He thinks it's just gonna be more boring adults telling him what to do, that is, until he sees his new sensei. He's quickly besotted by the man's kind smile, his sweet eyes, his honey-like tone and, most of all, the way he speaks to Katsuki. He makes him want to behave but inspires the utmost jealousy within the boy too, and the worst part is, he doesn't even realize what he's feeling.

Chapter 1: Enter: Kacchan

“Make sure you behave for Midoriya-sensei, okay Katsuki?” Bakugo Masaru said, glancing in the rear-view mirror to look at his four-year-old son, who was battling with the clasp on his car seat.

“Whatever!” The tyke said, unable to undo the blasted lock that kept him in place.

“Ah he’ll be fine, Masaru.” Bakugo Mitsuki said, grinning as she looked at her clone in the back seat. “He’s just energetic. Besides this daycare uses proper discipline! You hear that, boy? Behave or your little ass will be blistered!”

“Yeah I know!” Katsuki growled, giving up his battle with the car seat and crossing his arms in a huff, kicking his legs.

Meanwhile, across town, Midoriya Izuku was busy with the rest of his staff as they began to prepare for the day to start. Most of the kids had already arrived for the day, but he was still waiting for the last few to show up.

Taking a moment to step away from the group of children, Izuku made the decision to wait outside of his daycare for the Bakugo family’s arrival. Out of all the other children that he had his mind on, he was stuck on young Bakugo Katsuki.

He had learned of the child after a call from his mother, Mitsuki who was seeking to find a daycare willing to discipline her boy. If Izuku was honest with himself, hearing that had excited him. Not many parents were willing to sign the consent form to allow him and his staff to discipline their children, and he had a feeling that the woman was a bit of a disciplinarian herself. It was something he had to learn to own a daycare like his.

He wanted to meet the woman in person and speak to her privately for a bit. If there was a chance she was okay with him being more...severe than the law normally allowed when it came to corporal punishment, he needed to know. For all he knew, young Katsuki could be a little goldmine.

Izuku felt his heart thump like a drum in his chest. He saw a station wagon turn the corner, a fierce looking woman in the front seat. She looked like she’d fit the loud and boisterous voice he’d spoken to over the phone. His suspicions were confirmed when the car pulled to a stop in front of him. He offered a kind smile to the parents as the meek looking father stepped out and, looking rather bedraggled, went to take the thrashing child out of the back seat.

“Midoriya Izuku?” The woman asked as she stepped onto the curb, holding her right hand out while holding a backpack in the other.

“Yup, that’s me!” He said, taking her hand and shaking it. “You’re the Bakugos, yes?”

“Yeah, that’s us.” As she said this she looked over her shoulder, her face blanching as she watched her husband struggle to take their son out.

“He seems...excitable.” Izuku chirped, barely able to see the boy for all of his erratic movements.

“He’s a hellion.” Mitsuki said plainly. “That’s why I signed that consent form. Between you and me,” Her voice lowered and she leaned in. “my husband isn’t totally convinced yet, thinks it’ll mess Katsuki up.”

“You disagree?” Izuku suggested with a smirk and a raised eyebrow.

“To put it lightly.” She grumbled. “Anyway, I know there’s an official limit to what you can do but…” She trailed off, giving Izuku a look, a look that told him in no uncertain terms; “Do as you see fit.”

“I understand.” He said, watching as the other man joined them, holding a sulking, growling boy at arm’s length. “And you must be Katsuki-chan!” Izuku said, looking the adorable boy in the eye. “I think I’ll call you ‘Kacchan’ for short, how about that?”

“Whatever, idiot!” The boy spat, shaking himself from his father’s hold.

“Now now,” Izuku said, getting to a knee. “Here, my students call me ‘Midoriya-sensei’. You can say that, right?” He asked, knowing the indignant child would say it to prove a point.

“Of course I can!” Katsuki blurted with a puffed chest. “Minori-sensei!” He grinned as if he’d won a thousand victories.

“We...can fix that later.” Izuku said, standing tall again. “We’ll see you again at five?” He asked the parents. It was later than most of his children, in fact Katsuki would be the only one there for a whole half-hour, but he didn’t mind, he didn’t mind at all.

Izuku held his hand out to little Katsuki with a small smile before looking back up to his parents. “I can take him inside, unless you two would like to look inside and stay for a few minutes?”

“No, no, we’re sure you can handle it!” Mitsuki said, taking her husband by the arm and stepping back.

“Are you sure, hon, I mean it couldn’t hurt to-” Masaru said, but he saw the look on his wife’s face and knew that when they returned home...well, they’d be doing things they couldn’t for a long time since their son came into the picture. “I mean, yes, we should go, and leave everything in Izuku-sensei’s capable hands!” He said, bowing to the other man before darting back into the driver’s seat before his wife even got to the passenger door.

“Men.” She grinned to herself. She then handed Izuku the backpack, said a final goodbye to her son, gave Izuku a knowing look, and left.

Izuku softly chuckled and gave them a wave goodbye. ‘’Wave goodbye to your papa and mommy, Kacchan.’’ He urged, ruffling the tyke’s fluffy head of ash blonde hair. Izuku waited until the station wagon had pulled around the corner again to stand back up.

‘’Ready to head inside, Kacchan?’’ Izuku asked as he took a hold of the boy’s hand and led him inside to meet the other children and staff.

“Tch, sure.” He said, stuffing his hands into his pockets and stepping inside, ignoring the teacher’s outstretched hand.

Izuku couldn’t help but find the belligerence endearing. “We do have a uniform, Kacchan, in fact, we have one ready for you to put on in my office.” He said, catching up to the child in a few short strides as the boy took off his shoes and left them in a pigeon hole labelled with his name.

“What! Uniforms suck!” He said, kicking up dust on the tiled floor.

“Now, now, everyone has them, so you have to.” Izuku said, leading the boy into his own little space of heaven, his office. He closed the door and locked it to give them both some privacy.

“So, can you remind me what your quirk is Kacchan? Your mother said it was ‘Explosion’. Am I correct?’’ Izuku asked while laying out Katsuki’s uniform. Sitting down in his office chair, he gestured for Katsuki to stand in front of him so he could undress him and get him changed.

Katsuki turned his nose up at the gesture and insisted on undressing himself. Or he at least tried to. He took off his coat well enough, letting it fall to the floor haphazardly. He pulled his t-shirt out of his jeans and tried to pull it over his head but quickly got stuck.

“Here, let me help, Izuku chuckled, gently pulling on the shirt’s hem so it came off like a breeze. His mouth dried at the sight of Katsuki’s bare upper half. His skin was smooth, flawless and milky. He touched his hand against the boy’s back. He was almost hot to the touch and silky smooth. Words almost tangled in his throat.

“Now for your pants!” He said, acting as if his member wasn’t stiffening in his slacks. He was glad he always had a yellow apron on, otherwise he probably would’ve given himself away long ago. Not that his staff would’ve had anything to say about it.

Izuku lifted little Katsuki by his armpits and sat him on his thigh as he took off the boy’s socks before lifting him, grabbing the waistband of his pants and sliding them down his legs to meet his ankles, after which he pulled them straight off his feet.

Katsuki blushed a deep red. He hated to be manhandled, he hated to be controlled like that, but the man was so swift, so quick, that he didn’t even have the chance to protest. He just hoped that Izuku wouldn’t think of him as a baby because he, well...

Under Katsuki’s pants, the boy was wearing a white diaper with little cartoon All Might prints. Izuku’s cock twitched from within his trousers as he patted the boy on his bum. ‘’Are you a fan of All Might Kacchan? He’s my favourite hero too, you know.’’

“Y-yeah.” Kacchan blushed, crossing his arms in a flushed hush as the teacher sat him on his lap. “He’s the strongest! And I’m gonna be the strongest too someday!” He declared, a fist pumping into the air.

“I’m sure you will be, Kacchan.” Izuku said, standing and laying the boy on his back on his desk. “Now just let me check if you’re wet, after all, if I change you now, no-one else will have to know you still wear one.” He said this last bit in a whisper, winking at the boy.

“Like a secret?” The boy said in a whisper too.

The teacher nodded, resting his hands on Katsuki’s hips.

The freckled adult slowly unstrapped the diaper, one side at a time before pulling the front down to check the diaper for wetness, and secretly, to take a good look at Katsuki’s little dick and balls. ‘’You look all dry, that’s good. Can you pull your knees to your chest, Kacchan? I want to make sure your bum bum is clean.’’ Izuku said with a playful sing song voice.

In reality, he just wanted an excuse to see the boy’s back hole and rub his hands against his supple cheeks.

Katsuki’s cheeks darkened red. “My butt’s clean!” He said, pulling his knees back to prove as such. “See!”

“I see, Kacchan.” Izuku said, his hands trembling at the too-tempting sight. He let his hands rest on the boy’s pale cheeks, rubbed them, kneaded them, spread them and squished them. “You’re such a good boy!” He said, getting a grip and pulling his hands away from the naked child’s rear-end. “Now let’s get you dressed.”

They did so without much of a scuffle. Of course, Katsuki tried to do it himself but ultimately needed the teacher’s assistance, who was all too happy to oblige. By the end of it, Izuku couldn’t help but gush at how adorable Kacchan was in his baby-blue frock. He seemed to soak the praise up like a sponge and seemed to beam with pride when it was time to introduce him to the rest of the children.

Izuku clapped his hands together to get all the children’s attention, a kind smile gracing his freckled face. ‘’Hello boys, let's quiet down. Now, I want all of you to sit down on the rainbow mat. We have some new faces here today, so I’d like it if all the new boys can come up here and stand in a line, then when I say your name you can step forward and introduce yourself, and you can tell everyone your quirk, but you don’t have to if you’d like to keep it to yourself.’’

“I’m Eijiro!” The black haired, pointy-toothed boy yelled out first, sticking his hand in the air. He was without a doubt adorable, but Izuku had already conceded this boy to Shinso. The morose young man had taken to little Eijiro pretty quickly in the extensive interview his parents had insisted upon, and it was so hard for him to put himself out there and commit himself to a boy, so he was glad to let him have Eijiro.

“I can harden my skin!” Eijiro declared, holding his hands out. His hardening looked as if his skin turned to rock. He’d have to have a talk about being careful at playtime, he could see that the boy had already cut himself over the eye, probably with his very own quirk.

“And I’m Bakugo Katsuki!” Little Kacchan yelled, as if he were determined to be the loudest. “My quirk’s explosion and with it I’m gonna be the number one hero!” He held his hands out. Little sparks danced from the palms, almost like fireworks. Izuku had a hunch that it would be quite formidable when the boy got older, very formidable indeed.

The third and final new child stood still looking down at the floor and playing with the hem of his frock. Izuku kneeled next to him. “Come on Shoto, tell everyone your name.” He whispered, rubbing the boy’s back soothingly.

“M-my name’s Shoto Tod-” He cut himself off. “Just Shoto.” He said, fisting his frock. “And I don’t know what my quirk is yet.”

It was a lie, Izuku knew it was a lie. He’d had an interview with the boy’s father, a terrifying hero, famous and renowned, yes, but terrifying. He’d even signed the consent form that allowed him to spank Shoto if need be, and had been informed, even advised, to be as severe and strict as possible with him. He doubted he’d need to, and besides, Dabi seemed to have his eyes dead set on this one.

The freckled daycare owner gently patted the Todoroki boy on the head. ‘’Good job, Shoto-chan.’’ He praised softly just for the boy to hear. ‘’Okay boys, you can sit down again.’’ Smiling to the class, Izuku absentmindedly rubbed his hands together.

‘’Now this school has some rules that I expect all of you to follow. That board has a list of all the rules, but I’m going to go over a few points just to be sure you all understand. All of your parents were given a choice to sign a consent form with us. This consent form would give me and my staff the right to spank you if you were to misbehave. For the boys whose parents signed this consent form, I want you to understand to not expect to be punished privately if you are naughty. While most of the time any spankings that we must give will be done privately, we have the right to punish you in the same spot you earned that punishment. So if you’d rather NOT have the class see your bare little bottom, I’d advise you to not be bad.’’

Izuku narrowed his eyes and gave the rest of his class a stern look. ‘’BUT, I also have a zero-tolerance bullying policy. So for the rest of you, I don’t want to see any attempts to get other boys in trouble just so they can be spanked. If any of us learn you fabricated a story to get another classmate in trouble and they get spanked for it, you will be kicked out of this daycare and not allowed to return. Now let’s see… Mirio-kun, can you explain to the class the rest of the rules for me?’’

“Sure thing, Midoriya-sensei!” The energetic blond declared, standing up from the crowd of little boys. “First, no bullying!” He puffed his chest out, looking about as serious as a four-year-old could. “Second, no quirks during playtime! Third, be quiet when Izuku-sensei, Shinso-sensei or Hokuro-sensei is giving a lesson. Fourth, always go to sleep at naptime, or don’t make any noise so you don’t wake anyone else. Fifth, if something’s wrong, tell a teacher right away! Did I miss anything, sensei?”

Izuku laughed and held up a single finger. ‘’You missed one thing, Mirio, but you were close! Rule number six, no fighting. I only allow one type of sparring here and it’s done without quirks, both boys must agree to it and a sensei must be there to oversee. The rules are simple though, you can only wedgie your opponent and whoever gives up first wins!’’

Izuku kept a straight face for a few seconds before snickering to himself and waving his hands. ‘’Okay, okay, I was just joking about that part. No wedgie spars. And no fighting either. You can play wrestle with each other in the gym room on the mats, but you can’t be too rough and you can’t use your quirks. Got it boys?’’

“Yes, Sensei!” The class chorused.

Izuku kept a close eye on Katsuki as the day went by, Shinso kept an eye on Eijiro and Dabi on Shoto, just to make sure that they integrated well. The former pair did, but Shoto seemed content to play by himself in the corner and he shied away from anyone who approached. Dabi asked him if he was okay, but they both knew the quiet, reserved type when they saw them, and they also both knew that it was best to let them extend branches and socialise at their own pace.

After lunchtime, little Katsuki came up to him, red cheeked and uncharacteristically meek. He knew what it meant, the awkward shuffle, the playing with the frock, the staring at the floor.

“Midori-sensei…” He said in barely a whisper. “I’m wet.”

Izuku chuckled, took Kacchan by the hand and led him back into his office. It was an unspoken rule amongst the boys, they all knew what it meant to be suddenly led to the sensei’s office, and they all had silently agreed that nobody would be teased or taunted about it. It was a wonderful instance of daycare solidarity.

“Alright, clothes off.” Izuku said in a sing song voice, taking a seat on his chair and undressing Katsuki down to his diaper once more. It was much quicker, since all he wore was the frock and the loose pants underneath.

‘’You weren’t wet for very long were you Kacchan?’’ Izuku asked as he unsnapped the diaper and pulled it off from the four year old, leaving him naked as he stood in front of him. Izuku bagged the used diaper and tossed it into the trash, pulling a new one out of the backpack Mitsuki had given him. He picked Katsuki up and laid him down on his desk while grabbing some wet wipes.

“This is going to be a little cold.’’ He warned before gently pushing the boy’s knees apart, wiping his small willy and marble sized balls clean. Izuku softly pinched the tip of Katsuki’s member. Being very careful, he peeled back his foreskin to clean his pink little tip. The naked boy writhed and winced, arching his back and clenching his fists but still determined to show no registration of pain. Once he was finished cleaning him, Izuku gave him a sprinkle of baby powder on his shiny privates and thighs, then he grabbed both of his ankles in one hand, pushed his legs back and sprinkled more onto his peach-soft behind, making sure to pat it in with tiny little pats on his cheeks. Satisfied and painfully hard, the teacher snapped the new diaper on. ‘’There, all dry again. That wasn’t so bad.’’ Having Katsuki sit up, Izuku pressed a gentle kiss to his temple and gave him a warm, long hug.

Katsuki nuzzled into his sensei’s neck, something stirring in him, something new and unfamiliar. It made him want to stay there forever and never leave Izuku’s embrace. It wasn’t anything like when either of his parents changed him, not at all. This was warm and fuzzy, as if he were snuggling a cloud.

“Thank you for being a good boy for me Kacchan. I’m very proud of you.’’ Izuku whispered while nuzzling the child back. He placed a soft kiss on the boy’s cheek and wiggled his nose against his. ‘’Now let’s get you dressed again.’’ Izuku chirped.

“W-whatever!” He said, his palms sweating at the attention. Back in class, Bakugo couldn’t get the fluttery feeling out of his chest. He watched the sensei like a hawk, not letting him get out of his sight for too long during their hiragana lesson, or even lunch. Something hot and furious seized him when he saw another boy, Kaibara, approach Midoriya-sensei and whisper something in his ear, then they went to his office, just like they’d done.

He growled and scowled until they came back minutes later. How dare this brat get changed by his sensei! He clutched the colouring pencil in his hand so hard it snapped, causing the boy who owned it to go crying to Shinso-sensei. He’d been given a stern warning about respecting other people’s property and got off with a light slap on the wrist, metaphorically speaking.

When it was time for finger painting, Katsuki had the good fortune to end up next to the brat Kaibara, and, by a stroke of inspiration, he overturned a pallet of paint over his head so that his hair was now coloured like a rainbow.

He pointed and laughed at the tearful, plain looking boy, and was joined by several others, but that goody-goody Mirio approached him and took him by the hand to Izuku, his Izuku. He was fuming with indignation when he was pulled aside by the teacher.

Izuku pulled the young tyke by the hand, away from the group of children. He kneeled down to be on Katsuki’s level. ‘’Katsuki Bakugo. I am very disappointed with you young man. That was very mean to pour paint all over young Kaibara. You’re going to apologize to him, is that understood?’’ Izuku scolded sharply.

Fisting the front of his frock, Katsuki nodded, his cheeks heating red and tears on the verge of brimming his eyes. The look his sensei gave him, the tone of his voice, it all sent a shattering wave through his chest unlike anything his parents ever could. He sniffed, turning his head away.

Izuku’s gaze softened by just a tiny bit, before he pulled Katsuki into a light hug. But the purpose of it wasn’t to comfort the boy, it was to pull up the back of his frock, pull down the back of his pants and keep him still as he gave two sharp smacks against his bare thighs, before righting his clothes and pulling away.

“I want you to use your words like a big boy Katsuki. Don’t just nod to me. Now, you’re going to apologize to him. Understood?’’

“Y-yes sensei!” He said, forcing himself to keep tears from spilling. Walking away, he rubbed the seat of his pants with one hand while rubbing his eyes with his fist with the other.

He walked up to Kaibara, who’s hair was wet and clean and had Shinso-sensei kneeling next to him, rubbing a soothing hand up and down his back and Mirio holding his hand, promising that they’d paint something cool together.

He sneered internally, feeling it best to keep his behaviour in check for the moment. “Hey!” He barked, getting the trio’s attention and causing the sniffling boy to flinch. “That was...shitty…” He said, refusing to look at any of them. “I won’t do it again.” If he had pockets, he would’ve shoved his hands in them.

 

Izuku watched from a distance, a small smile growing seeing that Katsuki was apologizing. After a few minutes he made a retreat to his office to draft up an email for Mitsuki. There was a feeling he had in his gut when it came to the woman.

Izuku took about half an hour to type up an email for the woman. Inside sat a list of punishments, ranging from very simple and common, to a growing severity that would in many places be considered abusive. The list included items such as ginger figging, enema’s, and various other methods of punishments that he wanted her opinion on.

If she replied positively...perhaps he would be able to have a more personal chat with her.

Re-reading his email, he sent it and turned off his computer before returning back to attend the class.

Little Katsuki remained on his best behaviour throughout the day, but always seemed to be miffed whenever he left with another boy to either change him or see to anything else like a cut or a missed parent. He liked the idea that little Kacchan already grew attached to him, it made his heart flutter and his member swell.

The day ended, parents came and picked up their offspring until only he and Kacchan remained but even that ended all too quickly when Mitsuki and Masaru arrived. He did have a brief talk with the mother, asking if she got the email and what she thought. She had read it and explained that she was all for the harsher punishments, things that others might shy away from.

“He needs it, believe me.” She said in a low voice. “And coming from you it might make more of an impact on him.” She winked at him, and like that they were gone and Izuku and his staff were left to clean up for the following day.

The next morning came faster than Izuku expected, but that was probably from his own nerves getting to him. Knowing that Mitsuki had agreed with all of his ideas had the green haired boy-lover all excited at the future he had with little Katsuki.

“Hello Eijiro-chan, hello Sora-chan. Go on in and get your morning snack off the table and some juice okay?’’ Izuku gave each boy a high five or pat on the back. Seeing Mirio coming up the walk, his plain looking dad waving from his car, Izuku smiled and gave the boy a tight hug.

“Hey Mirio, did you sleep well champ? Ready for another fun day?’’ Izuku asked while scanning the parking lot for the Bakugo family’s car, but he had a feeling they wouldn’t be here for a few more minutes.

“I’m always ready for a fun day, sensei!” The blonde boy declared, pumping his fist in the air.

Izuku grinned and gave Mirio’s plump butt a stinging but playful smack to help him get inside. ‘’That’s what I like to hear! Go and get yourself a snack.’’ He teased with a smile, waving at Mirio.

Mirio giggled and rubbed the light, tickling sting on the seat of his butt, pushing his pants down just enough to show off his cheeks and let the unmarked slap breathe.

Izuku sighed. “The little nudist.” He muttered to himself, smiling and adjusting the growing rod in his trousers.

The Bakugos’ station wagon turned the corner before too long. Izuku grinned widely, he could practically hear the rambunctious tot jumping, screaming and scrambling to get out of his seat and into the daycare.

The little hellion was released by his father, who was alone this time, and he darted straight for Izuku’s legs, strangling them in a tight hold.

“Hiya, sensei!” He said, smirking up at him with a toothy smile.

“Good morning, Katsuki-chan.” He said, smiling warmly and kneeling to the boy’s level. “Wave goodbye to your dad.”

Katsuki gave a quick and careless wave to his father before following the other children inside. They went about their usual morning routine, snack-time, naptime, lesson-time and playtime. Katsuki, and most of the children, had been very well behaved until that last time. Playtime always ended up being the most troublesome, especially when young quirks got involved.

Izuku and his staff always had to try their best when watching over a group of boys with quirks. Whether it was Mirio who would slip out of his clothes and into the ground, or Sora and his ability to turn his fingers into locks which he would then forget how to turn back to normal. There were bound to be a few boys that got overlooked.

The sound of tiny explosive pops caused some of the children to jump in fright before a cry of fear came from one boy. Little Eijiro whose frock was smoking and slightly scorched while Katsuki stood in front of him, his hands outstretched.

‘’Katsuki!’’ Izuku scolded sharply before hurrying over to the two boys. “Eijiro-chan are you hurt? What happened?’’ Izuku asked softly while glancing at Katsuki with a glare to let the boy know he was in trouble.

The noirette hiccupped and sobbed as Izuku took him into his arms. “He, he burned me!” He said, rubbing at the crook of his neck where his baby-blue frock was singed.

“Let me see.” Izuku coaxed, petting the back of his hand. Relief flooded over him when he saw that the boy had hardened his skin in the nick of time, reducing what could have been a major burn to a minor tenderness. Still, it must’ve been scary to him, so he gestured for Shinso to take him while he took Katsuki by the wrist and into his office.

Katsuki remained wordless and wide-eyed throughout the whole process. He hadn’t actually meant to burn Eijiro, just scare him a bit. And that look, that glower that Izuku-sensei had given him sent tremors down his spine unlike anything else.

‘’Bakugo Katsuki I am very disappointed with you young man. You do not use your quirk to hurt or scare others. You are very, very lucky that Eijiro is not seriously burned.’’ Izuku grabbed his desk chair and pulled it away from his desk.

‘’Now I’m going to give you a good spanking on your bare bottom. Now arms up.’’ Izuku instructed while sitting down and grabbing the bottom of Katsuki’s frock and pulling it up over his head.

Katsuki’s words got caught in his throat. Usually he’d have something to say or at least try to struggle or argue his way out of a spanking, but that look, that ferocity in Izuku-sensei’s eyes told him that anything of the sort was a terrible idea. He raised his arms as ordered and didn’t blink when the man hooked his thumbs into his trousers and drew them down to show off his diaper.

‘’Now I want you to pee in your diaper right now. Since I’ll be spanking your bare bottom, I don’t want you to have an accident over my lap so instead you’ll pee right now.’’ Izuku took the blue frock and put it on the table. This left Katsuki without a shirt and his trousers at his knees.

Katsuki flushed red. “I, I won’t pee when you spank me!” He declared, taking a tiny step forward. It was one thing to wet when he couldn’t help it, but doing it on purpose was just too much for him. “I promise I won’t.”

Izuku sighed. He pushed the boy’s pants down to his ankles and gestured for him to step out. “Katsuki-chan, if you don’t do as you’re told, things will only be made more difficult for you.” The teacher folded the pants on top of the frock. “Now, do. As. Your. Told.” With the last word, he lay a harsh smack to the side of the boy’s leg, causing him to cry out and stamp his foot.

Izuku slipped his hand into his pocket and pulled out his phone. He secretly turned on the camera and set his phone on his desk in the perfect position to record every second of the punishment he was about to give out.

Katsuki’s lip trembled. The side of his leg had a big pink handprint on it, and it hurt! He didn’t want that to happen on his butt, but his teacher made it clear it was going to happen so he at least didn’t want it to happen too much. So, crossing his arms with a pout, Katsuki forced himself to wet his diaper.

Izuku watched as the diaper sagged slowly to indicate to him that Katsuki was wetting himself. ‘’Good boy Katsuki. Things will be easier for you when you obey your sensei.’’ He waited for the boy to finish before un-snapping each side of the diaper, bagging it and tossing it in the trash can. With Katsuki left to stand in just his shoes and socks, Izuku got a wet wipe and cleaned the blonde’s crotch without the gentle care and comfort he had before, instead remaining methodical and quick.

Tossing the wet wipe into the trash Izuku lifted Katsuki by his armpits and placed the nude boy over his lap. ‘’Now I won’t lie to you Katsuki-chan, this is going to hurt and you will cry. But I know you want to be a Hero, but Hero’s don’t use their quirks to scare or hurt their classmates now do they?’’

The freckled daycare owner cupped and rubbed Katsuki’s plump little cheeks before spreading them for the camera he had set up. ‘’You’ve been here for two days, Katsuki. Yesterday you poured paint on one boy and today you’ve almost badly hurt another. That’s two strikes young man. If you’re naughty again, I’ll have to be really tough on you and I don’t want that at all.’’ Izuku allowed Katsuki’s cheeks to bounce back together.

‘’I love you Katsuki, that’s why I’m doing this.’’ Izuku lifted his hand and gave two mean swats right across Katsuki’s cheeks. He gave the child a few seconds before lifting his hand and spanking him again. One smack every second with a moderate amount of strength. He would start with fifty swats as a baseline, if Katsuki seemed punished enough he would stop. If not he would keep going.

Katsuki bit his lip, just barely registering his teacher’s words amidst the stinging swats against his naked rear end. He was a resilient pup though, and refused to give in so easily. He fisted the fabric of Izuku’s trousers and steeled himself for the oncoming onslaught.

SMACK! SMACK! SMACK! SMACK!

Izuku was very careful not to put all of his power into the early smacks, he was happy to watch the boy’s cheeks bounce and clench as he lit them up, light pink marks forming on them before too long. Nearing the fifteenth smack Izuku lifted his right knee to prop Katsuki’s soft unmarked thighs and sit spots into the firing line of his big palm.

SMACK! SMACK! SMACK! SMACK! SMACK!
SMACK! SMACK! SMACK! SMACK! SMACK!

Ten more swats, these a bit harder than before bit into Katsuki’s lower bottom. Bringing the number up to twenty-five.

The boy was struggling to keep his composure. The burn was getting more and more intense with each passing spank. Not to mention his willy was beginning to poke annoyingly into his sensei’s leg, which only added to his frustrations.

“S-sensei!” He cried out as the thirtieth spank landed across the sensitive, light red sit spots. “Please!” He begged, a wet sob leaping from his throat as the brimming tears threatened to fall.

Izuku brought the punishment to a halt and gently rubbed the light red flesh. Any other caretaker would have stopped twenty spanks beforehand, but Izuku was far from finished. ‘’You should think deeply about what you did to young Eijiro. After this you will apologize to him and promise that you will be extra careful with your quirk from now on.’’

Gently stroking the blushing flesh a few more times Izuku lifted his hand and brought it down with over fifty percent of his strength. He carefully focused the majority of the next twenty swats to Katsuki’s butt cheeks rather than his sit spots. Bringing the full number to fifty like he had planned. ‘’You must feel like quite a naughty little boy right now Katsuki. Am I right young man?’’ Izuku asked sternly while giving the boy another small break.

Katsuki sobbed and bucked as those last smacks blistered into his bare bottom. There were more than he could count and it felt like they would never end, so when his teacher relented and questioned him, he was ready to say anything to end the whole thing.

“Yes! Yes!” He said, heaving where he lay. “I’ll be good! I promise!” He hoped that this would be enough to convince the man to end it, god he hoped it would.

Izuku rubbed Katsuki’s bottom for a few seconds before lifting his palm and bringing it down with his full strength.

SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK!

He counted the last ten in his head before lifting Katsuki up and hugging him tight. ‘’There, there. It’s over Kacchan. It’s over…’’ Izuku whispered as he rocked the naked toddler.

Katsuki was too preoccupied with the burning, searing pain in his backside to notice that it had stopped. He suddenly felt himself get crushed in his sensei’s embrace, whispering in his ear, as his bare bottom continued to smart and burn.

He wanted desperately to reach back and rub the sting away but his arms were trapped between his and Izuku’s bodies. He barely noticed how his little willy was still hard, poking into Izuku’s front, but the teacher certainly did.

“Now, you’re gonna do some corner time, okay Kacchan?” Izuku said, running his fingers through the boy’s locks. “You’re gonna keep your hands on your head and not move an inch until I say so. If you do, you’ll get more spanking, only this time I’ll bring you out to where everyone can see.” The man was sweating, barely able to restrain himself. He needed to nut, right this second, right now, and what better sight was there than a naked little boy’s red ass?

Setting Katsuki down he firmly pointed to the corner of his room. ‘’Do as I say, Kacchan.’’ Izuku reached over and grabbed his phone and turned it so the lens followed Katsuki into the corner. Then he sneakily pulled his cock out from his trousers and began to jack off as quietly as possible.

The boy’s plump cheeks were as red as a pair of cherries, large handprints clearly visible from top to bottom, down to his sit spots and thighs. He imagined how Katsuki would hiss every time he sat down for the next few days, reminded of the time he spent over Izuku’s lap, getting his soft, silky cheeks beaten and blistered.

Izuku bit his lip to repress a moan. The way Katsuki clenched and unclenched his cheeks, a visible sign of perpetual discomfort, sent sparks down to the tip of his swollen cock.

“Spread your legs, Kacchan.” He said, trying to sound as authoritative as possible as he felt his climax approach. “Wider!” He snapped after the boy’s feeble first attempt. He wanted to see the boy’s small, pink hole, he wanted to see his tight little sack dangle from between his legs.

Katsuki did as he was ordered without a second thought, not even entertaining the idea of disobedience. He spread his legs so wide that he had to step back from the corner. Whatever the reason, he hoped it pleased the teacher.

A few seconds spent staring at the image of little Katsuki’s spanked cheeks, pink twitching hole and tight sack in between his legs pushed Izuku over the edge. He used pure will power to hold back his moan as he exploded all over his hand. Hot cum splatted over his fingers and onto the underside of his desk.

The pervert stroked himself a few more times to get some of that remaining high in his brain before he licked up the mess on his hand and dabbed away the rest with a tissue. Once he was presentable and his cock was tucked back into his pants he called for Katsuki to come over to him.

“You can come here now Katsuki. I want you to tell me why you were punished, and what will happen if you’re naughty again.’’ Izuku said firmly, both hands on his knees.

Trembling and still crying, Katsuki slowly made his way back to his sensei, keeping his hands on his head just in case he wasn’t allowed to take them away again. Izuku looked much bigger than before when he looked up at the man again this time. The feeling of utter powerlessness before him sent some weird, new, electric feeling through his willy, a feeling that made him want to cover up, but his better judgement told him not to.

“I, I spilled paint on, on Kai-Kaibara,” He hiccupped and stuttered through the words, trying his best to say what he thought the man wanted to hear. “And I, I b-b-b-burned Eijiro-chan.” He said, looking away as another volley of sobs wracked his little body. “And, and if I’m, I’m naughty again, you’ll, you’ll spank me in f-front of everybody.” He said, sounding smaller and more pitiful than Izuku had ever seen a boy look.

‘’And those were very naughty things to do. I expect better from you Katsuki, heroes don’t bully people.’’ Izuku took a deep breath and pulled the boy into another hug. ‘’And that’s correct, if you’re naughty again you will get spanked in front of the whole class and far harder than what you got just now. So you be good.’’ Izuku whispered as he cupped Katsuki’s bottom and gently rubbed.

‘’And you can drop your hands now Kacchan. I forgive you. You still have to apologize to Eijiro, but between us, you’re forgiven.’’ Izuku pressed a loving kiss to Katsuki’s forehead before pulling back a little to look into his little red eyes.

“I love you. No matter what, I will always love you sweetie, but you have to be a good boy. I don’t want to punish you again.’’ Izuku whispered, half lying to Katsuki because he very much wanted to punish him again. Closing his eyes he held Katsuki again, this time for a nice long while, his big hand gently soothing the sting from Katsuki’s hiney until he was calm once more.

Katsuki buried his face in the man’s neck, taking in his sweet, musky scent as his large, cool hand soothed the bitter sting in his cheeks. The rocking almost lulled him to sleep, the warmth cocooning him like a warm towel after a bath. He didn’t want this moment to end, this small, beautiful moment that only existed for him and his teacher.

Izuku held the naked boy in the hug for a few moments longer, enjoying his sweet smell, rubbing his hand over his red and pained rear-end.

 

‘’There we go. Now I’m going to call for Eijiro-kun so you can apologize to him. After which you can get dressed again.’’ 

 

Katsuki nodded, already missing the man’s warmth when he got up and left. It was only a minute later when he returned, leading Eijiro by the hand. The other boy seemed to have gotten over the scare already. Katsuki blushed a furious red when the boy looked at him. He covered his upward pointing cock with his hands, more embarrassed to be seen naked by Eijiro than by Izuku.

 

‘’Katsuki. You wanted to say something to Kiri-kun correct?’’ Izuku prodded to get Katsuki talking. He gently patted Kirishima on the back, edging him closer to Katsuki.

 

‘’Katsuki’s naked because he just got spanked, but be open minded for what he has to say.’’ Izuku whispered into Kirishima’s ear before backing away to let the two boys have their moment.

 

The naked boy’s lip trembled. He wasn’t good at this, not at all. “I-” He started, but his words got caught in his throat. “S-sorry!” He blurted out, looking at the floor.

 

“Hmmm…” Eijiro crossed his arms, a thoughtful look crossing his face, his eyes closed in concentration. “Show me your butt!” He demanded pointing at Katsuki’s lower half.

 

Blushing furiously, Katsuki looked to his sensei, who only nodded, saying “Do you as he tells you.”

 

The blond turned, showing his red cheeks and thighs to the other boy.

 

“Whoa. That looks really sore.” Eijiro said, stepping forward and poking the middle of the squishy left cheek. Katsuki winced and hissed, jerking his hips forward to escape the rough touch. “Alright, I forgive you!” Eijiro declared with a big, toothy grin, wrapping his arms around the naked boy from behind, holding on tight and rocking back and forth.

 

Izuku happily smiled seeing Eijiro forgive Katsuki and even hug him. He was a kind child for sure. Stepping up to the boys he kneeled down and pulled them both into his chest. ‘’I’m very proud of both of you boys. Katsuki for apologizing, and Eijiro for you accepting it so kindly. I think you two boys could be good friends.’’ He kissed both of the boys on their cheeks.

“I promise that Katsuki will be more careful with his quirk now. He never meant to hurt you, he just needs to learn to be careful.’’ Izuku gave both boys another smooch and smile.

“Now Kirishima, since you got to see Katsuki naked, I think it would be really nice of you to let Katsuki see you naked, too. You can even stay in my office for a little play together. Naked wrestling is a lot of fun.’’ Izuku whispered with a wink. Saying it in a way like he was giving away a big secret. "So what do you think?’’

 

“Yeah! I wanna do that!” Eijiro said, visibly excited. Before Izuku could say another word the boy had already pulled his frock over his head and seated himself on the floor to pull his shoes off.

 

“Let me help you.” Izuku said, gently tapping the boy’s hands away slipping off his shoes for him. He then peeled off his socks, showing his most adorable little feet, and slowly trailed a hand up his leg, causing the boy to giggle. He slipped his fingers into the waistband of the boy’s pants and tugged them down his hips, revealing his briefs with pictures of Crimson-Riot on them. He pulled the boy’s pants down his tanned legs, causing him to harden in his trousers again.

 

“I think Kacchan should take off your briefs, Eijiro-kun. After all, you gotta touch his sore bottom.” He said, helping the boy to his feet.

 

“Oh, okay sure!” He said, not at all phased at the thought. Izuku made sure to catch every second of the interaction with his phone, Katsuki’s smug grin as he grabbed the waistband of the other boy’s underwear and pulled them down to his ankles in one quick action. Eijiro seemed to have even less humility than Katsuki, proudly standing there with his hands on his hips, his little member sticking up. Izuku couldn’t help but giggle when he saw that it was clearly longer than the other boy’s though he doubted either of them would know the significance of that just yet.

 

"Okay, I just have two rules. Don’t do anything that could break something in my office, and don’t hurt the other. Now then…’’ Izuku used both hands to smack each boy on their bottoms. "Get to playing. I will be back in a few minutes.’’

Standing to his full height he waved at both boys before slipping out of his office and quickly checking on the rest of the class and his staff to get an update from them.

 

Izuku nodded his head softly as he watched the children play. "I’m glad you guys have everything handled, I’m having Kirishima and Katsuki playing in my office.’’ He whispered with a small wink to Dabi and Shinso. The freckled adult frowned after a moment. ‘’And I got to piss, too.’’

 

Shinso glanced over to his boss once he heard that. ‘’Mirio just went to pee, too. If you’re quick you can catch him in the bathroom and have some fun with him.’’

Izuku’s eyes brightened considerably. ‘’Thanks for the tip.’’ He slapped both young men on the back before quickly hurrying to the bathroom and stepping inside.

 

‘’Mirio, are you in here?’’ Izuku asked while heading over to the urinal to quickly pee. ‘’I had a little challenge I wanted to see if you would like to take a shot at it.’’ 

 

The energic blond boy emerged from one of the three doorless stalls with a yell, completely naked and ready to take on anything!

 

“Whatever challenge you give me, I’ll do it, Sensei!” He declared, jumping up and down on the spot, his cocklet bobbing up and down with him.

 

Izuku’s face blushed bright red as he held back his laughter. ‘’Mirio, why do I always find you naked?’’ He teased with a giggle as he finished peeing. Tucking his cock back into his pants he walked over to the boy and ruffled his short hair.

“Well you’re going to need to wear your undies for this kiddo. It’s the hanging wedgie challenge. Three minutes hanging by the back of your undies. If you give up you lose and have to spend five minutes with a wedgie. If you win I’ll let you go naked for the entire day tomorrow!’’

Izuku grinned cockily. ‘’So what do you think? Want to take the challenge kid?’’

 

The boy brightened, the brightness of his eyes almost blinding the man. “Yes! I’ll do it! And I’ll win, too, just you see!” He said, darting back into the stall and reemerging with his blue briefs on. “I’m ready when you are, sensei!” He said, stalking up to the teacher with a fluttering giddiness in his chest. If he won he got to spend the entire day naked. That was the dream!

 

Izuku snickered into his fist as Mirio slipped on his undies quickly and came back out. ‘’I love that enthusiasm bud!’’ Leaning down he picked Mirio up by his armpits and carefully hooked the back of his undies over the stall wall. ‘’Remember you got to hang with your full weight. No cheating.’’ He held the boy out and away from him. ‘’Okay, ready? Here we go…’’

Izuku dropped Mirio all at once. Leading his underwear to be swiftly and brutally introduced to his butt crack. ‘’And time starts now!’’

 

Mirio winced when he dropped. The urge to let himself go intangible was there but he pushed it away, not wanting anything to get between him and his day of nude freedom! Still, it stung, but having Izuku-sensei there, watching him with that kind yet challenging smile, egged him on. It made him want to win more than anything because the way Izuku looked at him when he was naked made him feel like the most special, most extraordinary boy around! He didn’t particularly mind whether or not if he was naked before meeting Izuku, but after the first time the man stripped him down in his office, he’d had an accident and was in quick need of fresh pants and a clean cock, he’d gotten a penchant for nudity.

 

It didn’t take much for him to start stripping randomly, surprising his teacher with his bare body. There would be an initial shock for sure, but then he’d settle his gaze and look him over, staring at him with such a warm and caring expression that it made his little heart flutter.

 

It also did something he didn’t quite understand to his willy, but he figured out how to make it go down pretty quickly. He only had to rub it until a charge went through his body, a good-feeling one at that, and then it’d go down. He’d shared this advice with some of the other boys during naptime, and each time they came back to him with much thanks.

 

Mirio had the unique ability to hypnotize Izuku in a way. He could remember the first time he had ever seen the boy nude and he had been hooked ever since. In a way, Mirio was the perfect boy for someone like him. Always willing to be naked, always so eager to impress and lacking any sense of modesty.

“One minute down Mirio, two more to go!’’ Izuku cheered on with a smile as he gently spun the boy around from where he hung. Exposing his split buttcheeks to his eyes which he cupped and squeezed. ‘’You’re doing great Mirio. I’m so proud of you.’’

Izuku had come across many boys in his time and he had gotten attached to plenty of them, but that was such a quick way to get hurt. They never stuck around despite his best effort, or they grew weary of him and he had to back away for his own safety. And Mirio was one of those boys that had gotten into his heart and in a way he hated it. The chance of the boy staying around were low, and he would no doubt grow up, change and notice how wrong this all was.

 

It was happening with Katsuki too. He could feel him worming his way into his heart. 

 

Both of the boys were close by at least. Mitsuki was the most accepting parent he had ever meant. And Mirio’s father was so...cheerful and carefree that he would never notice. Not to mention the kindest man he had ever met.

 

So...maybe? Maybe there was more to his future then an eventual prison cell and angry inmates or a suicide to avoid being caught.

 

Yeah. He doubted it.

 

The minutes ticked away and Izuku was snapped from his reverie when he glanced at his watch and realised five whole minutes had passed.

“Whoa!” He said, promptly lifting the boy by the armpits and holding him on his hip. “You did it Mirio! You even lasted longer than I said!”

 

“R-really?” He asked, a tear brimming his eye but the broad grin plastered on his face told Izuku that he was okay. “Does that mean I win?”

 

“You more than won.” Izuku said, rubbing the tip of Mirio’s nose with his own. “You passed the challenge and then some, so, as a reward, you can go naked for the rest of the day today too.” He whispered the last part, squeezing the boy’s silly soft cheek as he did so.

 

Mirio squealed in delight. He wriggled for his sensei to let him down, pulling the wedgie out the moment his feet hit the floor and pushing his underwear down again, leaving him completely bare once more. Izuku’s mouth went dry at the sight of his boner. Another drastic effect the upbeat boy had on him.

 

“Before you go back, Mirio-chan, how about I give you a special treat?”

 

“Really, what?” He asked, seeming more excited than before, if that was even possible.

 

“I’ll show you, but you’ll have to keep it between us, okay?” He said, kneeling and whispering in the boy’s ear. “Our little secret. Can you keep a secret?”

 

“Yes!” Mirio said, his tone resolute.

 

“Good boy!” Izuku beamed.

 

Sitting down on the floor, Izuku helped Mirio sit down on his lap so he had his legs around his waist. His small fluffy butt pressed warmly on his hard on while his arm wrapped around his waist. ‘’This is going to feel a little funny, but I promise you’ll like it.’’ Izuku whispered as he took the boy’s little cock between his fingers and began to stroke him slowly.

 

‘’This is called masterbation, it's what big boys do when they feel horny. But little boys can do it too.’’ Izuku kissed Mirio on his button nose. ‘’Do you like it?’’ He asked softly.

 

“Yessss.” The boy almost melted in his hold. “It feels much better when you do it, Sensei!” He said, moving his hips back and forth.

 

Izuku choked on his spit as he looked up into Mirio’s blue eyes in shock. ‘’You masterbate, Mirio? How did you find out about it?’’ Glancing down at his cute little cock, he peeled the foreskin back to expose his pink tip. He used his thumb to rub and brush that sensitive little mushroom head and glands as he sped up his strokes.

 

‘’Maybe you need an even more special reward…’’ Izuku whispered to himself.

 

“W-what do you mean, sensei?” Mirio asked, his fists clenched onto the fabric of his teacher’s apron. “What’s better than this?”

 

“I’ll show you, Mirio-kun.” Izuku said in an eager, cheery tone. He brought the boy into the stall he’d been in, sat him on the toilet and kneeled before him, licking his lips. “You’ll need to try to be quiet, okay? Can you do that for me, Mirio?” Izuku asked, placing his hands on the naked boy’s shoulders.

 

“Yes!” Mirio said, nodding resolutely.

 

“Great!” Izuku smiled.

 

Eyeing Mirio’s little stiffy Izuku could feel his mouth begin to water. He slowly leaned in and pressed a soft kiss to the boy’s tiny smooth balls then another to his small tip. Opening his mouth he stuck his tongue out and flattened it to give a long lick from his balls all the way up his cock.

 

‘’So yummy…’’ Izuku purred lustfully. Closing his eyes he took Mirio’s little cock into his mouth and began to suck him gently. First only taking him half way and bobbing his head for a bit. Then pushing down farther and taking his whole cock into his mouth. Inside his wet cavern he flicked and rubbed the child’s cock with his tongue. From his glands, pee hole and shaft.

 

Mirio repressed a moan as brand new sensations washed over his body, electricity flying from his cock to the rest of his body. He bucked and thrust his hips into his sensei’s face, his small hands tangling themselves in the man’s green hair, that familiar, intense feeling shooting through him, but this time it was a million times stronger thanks to the work of Izuku’s mouth.

 

Panting, Mirio lay back as Izuku continued to suckly on his wilting cocklet.

 

Izuku gave Mirio’s throbbing and softening penis a few more soft sucks before pulling his mouth away and grinning up to the blonde boy. ‘’I hope you liked that Mirio. You just got your first blow job.’’ Leaning up slowly, he kissed him on the lips. He was slow and gentle before pulling back.

 

‘’Remember that this needs to stay our secret. We’d get in big trouble if people found out.’’ He gently kissed Mirio’s belly button before standing up. ‘’I’ll take your clothes to my office. But you have to get dressed before your daddy comes and picks you up okay?’’

 

“O-okay!” The naked boy said, lethargically pumping his fist into the air. He leaned back against the cistern, needing to regain his breath before going back to the pack. “Can we do this again tomorrow?” He asked, a blush tinging his cheeks.

 

Izuku softly nodded his head while gently ruffling Mirio’s hair. ‘’I’d love that Mirio. It sounds like a plan.’’ He leaned down and slapped his bare bubble butt. ‘’Now get going, my naked little hero.’’ He teased.

 

Giggling, Mirio hopped off the toilet and darted out of the bathroom as giddy as could be. Izuku bit his lip as he watched that adorable boy, and his luscious, pinchable behind run away from him. He hoped his staff would be able to keep themselves together for the next two days, the boy was very affectionate after all.

 

Smiling to himself, he made his way back to his office, Mirio’s clothes in hand, to see how his other two boys were doing.

 

“Oh boys, I hope nothing’s broken in here, if there is you’re gonna get a spanky!” He said playfully, covering his eyes as he entered the room. When he looked, his mouth fell agape at what he saw. Nothing was broken, in fact it seemed as if the pair of naked boys hadn’t moved from the spot he’d left them in at all.

 

Katsuki was on his back, his chest heaving, his nails scraping at the carpet as Eijiro, his eyes closed in concentration, was jutting, rubbing and grinding his hips against the other boy’s, a hand reached down between them, holding both of their small cocks in a grip.

 

He blushed, his cock springing to full mast in his pants, a dribble of precum leaking into his boxers.

 

“K-Kacchan! Eijiro-chan!” He stammered, closing the door hurriedly behind him as he entered the room.

 

‘’Just what kind of wrestling are you two doing?’’ He semi-squealed in a shocked tone of voice. This wasn’t what he had been expecting to walk into! Part of him was badly jealous, another part was eager to join, and a third was worried as hell. Eijiro was Shinsou’s boy but he wasn’t sure how far the purple haired teen had gone with the boy yet. Or if he had yet to successfully get Eijiro to understand that this kind of play had to be kept secret.

 

“Oh! Izuku-sensei!” Eijiro said, shooting the teacher a grin as he paused his rutting. “I’m just showing Katsuki-chan the good feeling thing that Mirio-chan told me about!” He said, pulling his hips back and pointing to his standing cocklet. “See? He said that when it gets all pointy, you just have to rub it like that and it goes away.”

 

A wave of relief flowed through Izuku. Okay, if this got back to a parent, he’d just have to let them follow the trail back to Mirio, which meant he only had to tell Mirio to make sure he says that he found it out himself. He hadn’t shown the boy how to masturbate, but suspicions could be raised if three boys were found playing with their cocks in his daycare, a daycare in which corporal punishment was allowed.

 

“O-oh.” He said, kneeling in front of them. “That’s great, Eijiro-chan.” He said, patting the boy on the head. “But you shouldn’t be touching other boys on their peepees when you’re alone, you might hurt yourselves.” He said, trying to think of something, anything, to say to get the boy to not say anything at all without arousing suspicion. Eijiro wasn’t as enamoured with him as Katsuki and Mirio were. He’d have to talk with Shinsou about this, and Mirio too while he was at it.

 

‘’Let me get Shinsou-sensei, I’m sure he can explain more to you Eijiro-chan.’’ Izuku gave the raven a small smile to show that he wasn’t in trouble before getting up and poking his head out the door where he locked eyes with Shinsou.

 

‘’Shinsou-kun. Can you come to my office real quick?’’ 

 

He made a quick gesture with his hand that the zombie-like teen caught.

 

Walking over to his bosses office, he raised a tired eyebrow as he was allowed in. ‘’What’s up?’’ The lavender haired sensei nearly choked on his spit as he got a good look at the two very nude boys and the naughty position they were still in.

 

Izuku gave his employee a weak smile. ‘’Kirishima was showing Katsuki-kun how to make his penis go soft when it got hard. He said he learned it from Mirio-chan. I was telling him that they could hurt themselves if they did it alone. But I thought that you can handle that talk with Kiri for me while I handle Katsuki and later Mirio.’’

 

Shinsou let his shoulders sag in understanding, his surprised face melting back to its tired self. Save for the tent in his pants. ‘’I see. Okay Eijiro, let’s get you dressed and you and I can have a little talk. You’re not in trouble, I promise.’’ He added softly as he patted the boy on the head.

 

Izuku smiled and looked down at Katsuki. “I should get you dressed too Katsuki and have us all rejoin the rest of the class.’’

 

Eijiro and Katsuki looked disappointed to have to stop already, both of their cocks were still sticking up, but they obeyed their teachers’ orders without protest. Shinsou redressed Eijiro promptly and lead him by the hand out of the office to have their little talk. Izuku stood Katsuki in front of him, facing away, so he could inspect his cherry-red butt.

 

“You must still be stinging, huh Kacchan?” He asked, running his hands soothingly over the soft cheeks.

 

“Uh-huh.” He said, crossing his arms impertinently. “It hurts!” He said, wiggling and clenching his hindquarters.

 

Izuku chuckled. “How about this, you don’t have to wear your pants until the end of the day. That way they’re not rubbing against your sore little tushy?” Saying this, he gave the right cheek a little pinch.

 

“Can I not wear the diaper too?” He asked excitedly, turning to face the man.

 

“No, you still have to wear that. You still can’t go potty properly and I know you wouldn’t wanna wet yourself in front of everyone else, right?”

 

“Guess not.” Katsuki said with a pouty, defiant blush.

 

“There, there, you’ll get it eventually.” He smiled, kissing the naked boy on the cheek. “Come on, I’ll give you a little treat as I’m dressing you.” He winked, picking Katsuki up and laying him on the desk. “I’ll show you what Eijiro-chan was talking about.”

 

‘’I love you, Kaachan.’’ He whispered lovingly as he began to slowly jerk Katsuki off with his larger adult hand. Unknown to Katsuki, Izuku had an evil scheme forming in his head as he masterbated the younger boy.

 

He waited and watched carefully so that when he noticed Katsuki’s toddler orgasm start to build and almost erupt he would be able to let go and deny him his orgasm.

 

He did always wonder how a little boy would react to some edging compared to some adults reacted to it.

 

Katsuki threw his head back and moaned, his body writhing, a new, unfamiliar building up in his gut. It was just like when Eijiro had been grinding against him only more intense now. Noises flew from his throat as he felt that pressure build and build, his willy spasming and twitching until-

 

Izuku smirked as he let go of Katsuki’s little twitching willy. ‘’Oops! Sorry, my hand slipped off.’’ He didn’t grab Katsuki’s cock right away, instead he gently rubbed his tiny sack and waited till his cock stopped jumping and spasming. Only then did he start jerking him off again, but at a slower pace.

 

‘’You must have been so close to that sweet feeling. Don’t worry Kaachan. I’ll get you there.’’ He whispered teasingly.

 

The boy’s blush deepened at the man’s tone. Something about it lit a fire in his stomach that he didn’t know what to do with. The slow pace of the man’s strokes were almost torturous, yet nothing compared to his formidable spanks. He could feel that new, wonderful feeling build up again. His body twitched, he threw his head back, he squeaked and groaned until again, that pressure built up!

 

Izuku didn’t let go of Katuski’s cock this time but he did stop jerking him off. Ending the build up for a second time and forcing the boy to be denied a second time in a row. ‘’Mmmm I know, Katsuki. You want it really bad don’t you?’’ 

After a few seconds he began to jerk the boy off again, building him up to that sweet release a third time with that same slow pace before denying him again...and again...and again.

 

“Senseiiiii!” Katsuki moaned, thrusting and bucking his hips. “Please!” He begged, his lip trembling at the constant teasing. He knew what he was supposed to feel but the constant denial, that explosion being withheld from him made him want to cry. “Please, it hurts!” He almost sobbed.

 

“Okay okay, no more teasing. This one is going to be the big one. I promise.’’ Izuku whispered as he stroked his little toddler fast and hard. He had tortured little Katsuki for long enough, now it was time for his reward. ‘’Cum for me Katsuki-chan. Cum for Sensei.’’

 

Katsuki let out a throaty moan as the dam that had been building up in the pit of his stomach burst, and a veritable explosion of colors burst through his body! It was unlike anything he’d ever felt before, it felt better than anything he’d ever experienced! It felt like his body was melting and wringing and stretching all at the same time.

 

In a moment, the euphoric climax died down and sense came back to Katsuki’s addled brain.

 

“S-sensei.” He said, a groggy hoarseness drying his throat.

 

Katsuki had a dry orgasm which was no surprise to Izuku, but it had clearly been a powerful one. ‘’Did that feel awesome or what Kacchan?’’ Izuku teased as he stroked his little cock a few final times.

Izuku pressed a kiss to Katsuki’s belly while letting go of his cock. ‘’Now let's get you dressed sweet pea.’’ Grabbing a diaper, Izuku carefully slid it under Katsuki’s bottom and then taped him up. “Sit up for me Katsuki~.’’ The freckled adult helped the boy put on his baby blue frock.

 

The rest of the day passed by without much more excitement. Mirio was happy to go streaking, even after their little chat where he explained that he shouldn’t just show other boys how to play with their weiners, and that if they’re having such problems they should talk to a grown-up, preferably their parents. Of course, he had no true issue if a hard boy stroked himself at the daycare, but he didn’t need the bother if the topic of masturbating tots got back to a parent and he didn’t have plausible deniability.

 

He dressed the little nudist moments before his father collected him, and after Kacchan was gone, pants on and a note explaining his spanking for his parents, he and his staff cleaned up shop and awaited the next day.

Katsuki tossed and turned on his bed, still feeling the red sting on his bottom that his teacher had given him earlier that day. Thoughts of the man came and went, as well as flashes of Eijiro and how he and the boy had grinded against each other while naked and of how Izuku-sensei had rubbed his hard willy between his fingers until an amazing feeling blazed through his body.

With a growl, he pushed himself up from his facedown position and stomped over to his mirror, lit up by his orange-glowing night light. He was stark naked, his little cocklet standing tall after reminiscing over the day. He grabbed it in his fist and pumped it up and down, a small spark shooting through his body. He let out a small mewl, not wanting to alert his parents.

Katsuki felt his heartbeat quicken as he pumped his little willy as fast as he could. Izuku-sensei’s hands had felt so much better on his little penis than his own did, but if he kept his eyes closed he could imagine that it was his sensei touching him down there. More mewls of pleasure escaped past his tiny lips as he used his other hand to reach back and rub his small red bottom.

He wished he had his sensei to rub his little tush. Izuku-sensei had such big and warm hands...they could hurt him so badly but they made everything feel so much better afterwards too. ‘’Sensei..’’ Katsuki cooed, his voice barely a whisper as he felt the fire in his belly grow hotter.

That explosion he’d felt erupt in the pit of his stomach flared through him again! He let out a grunt, almost feeling as if something shot out of his willy, but nothing did. Panting, he returned to his bed, face down, his red bottom out for the world to see, and within minutes, he was snoring lightly, dreaming dreams where he was in his sensei’s arms, his willy being touched and pulled and stroked all night long.

The following morning, Izuku was eager as all hell to see his little Katsuki again. He imagined the boy had had a rough night, given the spanking he’d received. Still, he hoped the boy wouldn’t hold it against him, especially given what he’d done to him afterwards.

As they all began to file in, some parents staying until the bell rang, others leaving immediately and some not even coming in, Izuku kept a keen eye out for Kacchan. He came in, looking very sorry for himself indeed. His eyes were slightly red, showing he’d been crying, and he walked very stiffly. Izuku felt a stirring in his groin at the thought of Katsuki’s red rear end. He pushed the thought aside for a moment as he saw Shoto walk in all on his lonesome, looking very...shaken. He wore no expression but seemed to tremble and flinch with every move.

“Sensei!” He heard Katsuki yell. He looked down and the boy had wrapped himself around his legs, a bright smile on his face.

“Good morning, Kacchan.” He said, ruffling the boy’s hair. He leaned down and whispered in his ear. “I hope your bottom’s okay.”

The boy blushed and shook his head. “Hurts!” He said, sniffing.

“Well, we’ll do something about that later.” He said, giving him a small wink. “But for now, go play.”

Izuku patted the boy on the head to send him off on his way before heading over to young Shoto to say hello to him, and to comfort the clearly upset child.

Reaching the young boy, he took a knee and gave him a comforting smile. ‘’Hello Shouto-chan, how are you feeling this morning?’’ Izuku held out his hand and gave the boy his warmest smile.

“I’m okay.” He said, barely audible, especially in the room of boisterous boys, “Midoriya-sensei.” He seemed to not want to say anything else, so Izuku silently led him to the rest of the group, taking his place in front of them all next to Shinso and Dabi. Dabi gave a warning glance out of the side of his eye. He simply smiled in response, not intending to step on the other man’s toes.

They proceeded with the day’s activities, starting with toy time, then colouring, then the hiragana lesson followed by nap time. It was then that something out of the ordinary happened. Izuku heard a soft sobbing in the far corner of the room. Ever the worrier, he shuffled silently through the litter of small, unconscious boys, unable to not look at adorable and good-natured Mirio, who was completely naked, lying on top of the covers. His member stirred at the sight of the little boy, curled up in the nude, but he had an actual job to do, and he was nothing if not prideful in his work.

He got to the source of the soft sobbing, little Shoto, who had drawn his covers over his head. By the smell, Izuku could immediately tell what had happened. Crouching down, he spoke softly to not startle the boy.

“Hey Shouto-chan, it’s just me and you don’t have to be embarrassed or scared. Let’s get you to my office with Hokuro-sensei so we can help tidy you up. Okay?’’ Izuku whispered as he rested a hand on the blanket, rubbing the boy on his back in a soothing gesture. Looking over across the room, he waved the perpetually-scowling employee over to come and help him.

Shoto said nothing, he lay completely still when he was picked up and cradled into Midoriya’s office. “It’s okay, I have everything we need to make it seem like it never happened. Dabi-sensei, could you undress him please?”

Dabi, who had been silent up until now, took the trembling boy from his boss’s arms and went behind the desk. He stood Shoto on it, the boy’s eyes downcast. “Arms up.” He said, lifting the frock over his head. “...good boy.” He said, barely able to think of a compliment that didn’t sound as if he were praising a puppy.

He didn’t waste any time in hooking his thumbs into Shoto’s pants and underwear, drawing the sodden clothes down his pale, milky legs and gesturing for him to step out of them. He did, moving his hands to cover his small boyhood, tinges of red permeating his cheeks.

Izuku, with baby wipes in hand, gently patted the back of the boy's palms.’’It’s okay Shoto-chan, you don’t have to hide your wee wee from us. We’ve seen plenty, yours won’t be any different. I promise.’’ Just to make sure Shoto could trust him, he crossed his heart. With Shoto’s hands moved out of the way, the daycare owner gently wiped Shoto clean, taking care with his little pink tip like he always did for the boys.

Dabi couldn’t help but soften his expression as he felt the grip of Shoto’s tiny hand around two of his fingers. His eyes darted to the side, spotting a tinge of red on the side of Shoto’s bare behind. He craned his head to look and saw a series of dark red hand-prints littering the boy’s plump cheeks. He ghosted a hand over the skin, feeling the heat from them, his jeans tightening.

“You got spanked, huh?” He asked, taking another wet wipe as Izuku stepped back to get some spare clothes and running it up and down the inside of Shoto’s thighs, his eyes focusing on the boy’s small, erect member. He turned the boy around, pulled one cheek to the side and started to wipe up and down the crack, glancing over his pink hole as he did so.

Izuku forced himself to grimace at the damage displayed across young Shoto’s cheeks. The size of the handprints were from that of a large man, no doubt from Shoto’s father. ‘’Ouchies, that sure looks like it hurts.’’ Izuku said sympathetically as he laid out a spare change of clothes. Smiling softly, he tapped Dabi’s shoulder.

“You know Dabi, I bet Shoto would feel a lot better if you shared some of your special lotion with him. Maybe a nice butt rub will help him fall asleep too.’’ Izuku suggested, smiling at his burned best friend.

“Yeah,” Dabi said, biting the inside of his lip to keep from breaking out into a massive grin. “I think that’ll do the trick.” Dabi went to the lockers in the corner of the room where he, Shinso and Izuku kept their more private things. He unlocked his and took out a lavender, labelless bottle.

“This’ll do the trick alright.” He said, sitting in the chair behind the desk and pulling Shoto onto his lap such that the naked boy was kneeling on his thighs. He popped the bottle open, squeezed a small dollop onto his hand and began to massage it into Shoto’s red butt-cheeks.

He felt the boy stiffen at the contact so he pulled him closer. He could feel his member poke him, the fact the boy was erect making him hard even moreso.

“How’s that?” He asked, resting his chin on Shoto’s bicoloured hair.

Shoto clenched the fabric of Dabi-sensei’s shirt, his cheeks red at his own nudity and the touch to his bare bottom. But...the touch wasn’t so bad. Not like his daddy’s touch. ‘’It..it’s okay…’’ Shoto whispered shyly as he hesitantly pushed his sore bottom into Dabi’s hand while burying his face into the corner of his neck. ‘’Keep going...p-please.’’

Izuku watched the scene with a kind smile, his pants tented at the alluring and adorable sight. “Dabi-sensei will take good care of you Shoto-chan, you can trust him.’’ Leaning down, he pressed a kiss to the child’s temple before giving Dabi a small wave and wink as he left his office and went back out to check on the other children, and clean up the wet spot Shoto had left behind.

Unbeknownst to him, Katsuki was seething a few futons away, barely able to keep his hands from detonating. How dare Shoto go into his sensei’s office! That bedwetter didn’t deserve to have such privileges! That was his and Izuku-sensei’s special place! Where they’d play their special game during their special private time!

He’d have his revenge, he knew that for certain.

The mess little Shoto had made was cleaned up quickly by Izuku and after another forty-five minutes, nap time came to an official end with the help of Izuku and Shinso waking up all the boys and slowly turning the lights back on.

“Okay boys, if any of you need to use the potty, raise your hands so you can go to the bathroom. And for those that don’t think so, I want you all to try to go anyways after the boys who DO need to use the bathroom are finished.’’ Izuku clapped his hands to help get all the boys' attention.

‘’And if you need help you can come to me or Shinso. We are always here to help.’’

Izuku was excited for the next activity, pool time! The daycare had its own, a rather small, shallow one that was just the right size for a rambunctious group of little boys. Though he didn’t say it out loud, his favourite part was watching all of the boys change into their swimsuits, many of them needed help and some of them didn’t even bring any, so he’d let them skinny dip. Mirio was one of those boys, even if he didn’t have the go ahead to stay naked for the day, he wouldn’t have brought one. The boy was an exhibitionist, through and through.

It was great.

Katsuki was actually excited about the activity. He didn’t have a swimsuit, or even underwear to substitute, and like hell was he going in his diaper, so he’d have to go naked, and he wouldn’t have it any other way.

As the other boys changed in the main room, many of them taking their time to run around completely bare, not a care in the world, he went up to Izuku-sensei and, putting on the most bashful display he could manage, said this;

“Izuku-sensei, I don’t want the other boys to see my diaper.” He touched his fingertips together, a small hint of truth in the statement.

“Hm?’’ Izuku glanced down, acting as if he hadn’t been watching Katsuki and had seen him coming up to him. ‘’You don’t want them to see your diaper? Well, I guess I can help you with that.’’ Offering his hand to Katsuki, he led the little toddler to his office where they could be private with each other.

‘’Do you want to undress on your own? Or would you like your sensei’s help?’’ Izuku didn’t bother making his question sound much like a question. Izuku had a feeling that they could both read each other pretty well by now, and he made it plenty obvious he wanted to be the one to strip Katsuki naked.

“I want your help!” Katsuki said, losing all hints of embarrassment.

Hand-in-hand, they went into the familiar room and Izuku took his place behind the desk, moving Katsuki to stand between his legs. He placed his hands on the boy’s hips and ran them up his sides and under his frock until he pulled it over the boy’s head. Tossing the frock away to the side, Izuku wrapped his arms around Katsuki’s middle and squeezed his butt through his pants while gently pressing his lips against the boy’s little button nose.

 

Sinking his fingers into Katsuki’s waistband, he dragged his pants down until they dropped to his little ankles. After helping him out of them, he carefully unstrapped the diaper and pulled it off. ‘’There we go, now let me see your bum.’’ Izuku whispered as he turned Katsuki around to see the damage he had done to the child’s bottom.

“You’re redder than I thought you’d be? Did your momma spank you when you got home?’’ Izuku asked softly as he gently rubbed Katsuki’s cheeks.

“Mm-hm.” He mumbled, enjoying the attention his sensei was giving to his sore bottom. It had hurt so much even though she’d only used her hand. “I had to stand in the corner forever afterwards.” He complained, feeling that odd stirring in his willy again. “But you make it feel better!” He said, pushing his rear back against the man’s hands. “Can you do the thing you did yesterday again? Please?” He asked, turning his head to look up at the man.

A rush of blood filled Izuku’s cock and his cheeks turned pink. ‘’Of course, anything for you Kacchan.’’ Izuku happily whispered as he lifted Katsuki up and laid him down on his desk. ‘’You don’t have to pee do you?’’ He asked as an afterthought as he kissed Katsuki’s forehead, peppering his way down with little pecks, kissing his cheek, neck, chest and stomach before reaching his crotch. He pulled away, debating whether or not to fellate the boy. He decided not to, not yet, as to not risk scaring him away.

Izuku decided to simply jerk the boy off for now. He made a small circle with his thumb and pointer finger and began to stroke the boy. ‘’Lets see if I can make you feel a little bit better.’’ Izuku added some spit to the mix so he could hold Katsuki’s foreskin back and allow his hand to glide uninterrupted over his small sensitive glands and tip.

Katsuki’s top cheeks tinged a deep red as his bottom ones stung against the wood of the desk. He couldn’t stop the sounds that escaped his mouth as that fiery feeling spread through him again, sending electric pulses through his entire body. He clutched onto his sensei’s arm, fisting the fabric of his shirt as his toes curled, his legs pushed together as that pressure built up in his gut and-

Katsuki’s member pulsed and throbbed as he orgasmed, shooting non-existent cum into his sensei’s hand, his brain a mile high as it experienced an overload of pleasure. Panting, he fell back, ignoring the sting on his red butt.

“That felt amazing!” He said, feeling his sensei’s fingers begin to slow and stop stroking his cock. Then, an idea popped into his mind, one that he knew would make his sensei like him more than Shoto or any other boy. “Can I do it to you?” He asked, sitting up.

Izuku’s green eyebrows nearly vanished into his hairline, his cheeks burning pink. ‘’You want to jerk me off?’’ Izuku asked just to make sure as he didn’t know what to say to that request. It sounded hot and enticing as hell too. But…

Izuku shook his head no with a sad smile. ‘’How about later? We don’t want to keep everyone waiting and I don’t want you to miss out on any swimming time. But once we get time I’ll let you do it. Does that sound okay, Kacchan?’’

“Hm! Okay.” Katsuki said, crossing his arms with a pout.

Izuku led the butt naked boy back to rest by the hand, his eyes immediately darting to the other naked and half naked tots, his cock leaking into his underwear at the sight. Eijiro was naked, chasing TestuTetsu who had his swimsuit held in the air, Mirio was helping Kaibara strip down, Amajiki was hiding behind Shinso’s legs as he slid his trunks up. Dabi was helping Shoto, holding the boy’s speedo out for him to step into. His heart panged for the sweet boy, his red rear would be out for all to see. Then again, so would Katsuki’s, but he imagined the other boy wouldn’t mind that much.
Izuku gave Katsuki’s little hand a small squeeze before letting him go. ‘’Okay boys, those of you who don’t have your swimsuits on yet, put them on. Tetsu-chan, give Eijiro-chan his swimsuit.’’ He scolded softly while giving the boy his ‘stern’ face.

The silver haired boy pouted but did as he was told after being called out, tossing Eijiro’s swimsuit to him. Eijiro caught it with a fumble and was quick to slip into it.

Izuku smiled as TetsuTetsu did as he was told, his eyes turning to the two naked boys out of the group. ‘’Mirio, Katsuki. Since you two don’t have your swimsuits you don’t technically have to go and swim. But I have a feeling neither of you have a problem with that. Am I right?’’

“Nah.” Katsuki said, swaggering over to join the group.

“Not at all!” Mirio said, shooting his sensei a broad grin and giving him a thumbs up.

“Alrighty then, off to the pool!” He declared to uproarious cheering, a stampede of half-naked boys racing out to the back. Izuku glanced at Shinso. The teen’s knuckles were white with how hard they were grasping the edge of the table he was leaning against. As he walked after the crows of boys, he leaned in to whisper to the other.

“My office is free, use it and be back in ten minutes.” He winked, knowing that he was more than likely sporting a rock hard boner in his pants.

Shinso looked relieved and strolled off in a hurry, Dabi sneering; “Amateur.” when he was out of earshot.

“Be nice!” Izuku chastised. “He’s still new to this, seeing so many little boys naked at once would do that to anyone...like us.” He said in a low whisper as they emerged out the back entrance, the boys already splashing and playing in the water. The two teachers stood sentinel at the edges of the shallow pool, patrolling around it to make sure all were behaving.

Izuku scanned the pool, making sure everyone was behaving and okay as he walked past Dabi. The tiniest of smirks gracing his lips. ‘’I’m not afraid to spank you two either if you can’t play along.’’ He whispered as he winked at Dabi. He gave the scarred man’s bottom a firm smack on his way past, the boys in the pool unaware in the midst of their fun.

Katsuki caught the sight of Shoto out of the side of his eye. The half-’n-half brat was playfully splashing with Mirio. He told Eijiro that he’d be back in a minute as he began to approach the boy. He’d not forgotten that he’d gone into his sensei’s office. The thought sent anger blistering through him. He kept his hands in the water to stop them from smoldering. The last thing he needed was to hurt another boy with his quirk, this time one with literally nothing protecting him, he got lucky that Eijiro had hard skin.

He didn’t know what he’d do once he reached the meek boy, but when he called him and he turned to look at him, his anger boiled over. He didn’t realise he’d grabbed the boy by his shoulders and pushed him under the water until he felt pulling at his arms, Mirio on one side and TetsuTetsu on the other.

Dabi had waded into the water to pull a gurgling, coughing and crying Shoto into his arms. All the boys were so stunned by the drama that no one except the senseis noticed the crystals of ice that had floated to the pool’s surface.

‘’Bakugo Katsuki!’’ Izuku stood on the edge of the pool, his green eyes slitted in anger. ‘’Get out of the pool, NOW young man.’’ He turned his head towards the building. ‘’Shinso, get out here we need you!’’ He snapped before turning his piercing gaze onto Katsuki. ‘’I said, Get. Out. Of. The. Pool.’’

Katsuki froze where he stood. Suddenly everyone was looking at him. He was naked, and everyone was looking at him. He flushed a deep red, and then he caught Izuku’s eyes. He was pissed. The man’s words finally registered with him and he started to silently wade through the pool until he reached its edge, where he was lifted by the armpits and stood roughly onto the ground.

Izuku lifted his hand high and brought it down with a thunderous affect across Katsuki’s wet, bare little ass. Five deafening smacks echoed from out behind the building. The man didn’t leave an ounce of mercy for the boy as he hit him with all his strength. ‘’Stand at this corner. Do not move until I tell you. You are in BIG trouble young man.’’ Izuku knew he was being harsh, but this was unacceptable.

He turned to look at Dabi as Shinso finally came running out. His cheeks flustered and his forehead sweaty. ‘’Shinso, replace Dabi. Dabi, take Shoto inside and make sure he’s okay.’’ Izuku rarely spoke in the tone he was using now. But when he did, even his employees knew better than to argue with him. ‘’Everyone else...if I see anyone get dunked again. I don’t care if your parents haven't signed the form. I’ll whip your butt! Now go back to playing.’’

Katsuki was mortified. He was being made to stand there, where all could see his bare, red ass, for god knows how long. He could hear them all having fun as his butt smarted from those five blistering smacks Izuku had given him. He wanted to cry, he wanted to cry so bad, but he absolutely refused to do so while everyone could still see him.

The minutes ticked by and pretty quickly, Katsuki realised he needed to pee, only, he hadn’t realised soon enough and it wasn’t until he was already peeing that he felt it. Right there, in front of everybody, he was essentially wetting himself. At least he wasn’t wearing the diaper, that would’ve just been too much.

The mood was somber for the rest of the activity for the other children. Izuku felt a bit guilty over that but he could just have another swim day to make it up for all the good children. “Okay, swim time’s over. Everyone get on out and dry off.’’ Izuku turned to Katsuki and grabbed the boy by his ear.

“You’re coming with me young man.’’ Izuku scolded him as he pulled Katsuki into the daycare so he could be dried off.

Once he had Katsuki dried off he led him by his ear into the main room of the daycare and forced him to stand at the front of the room as all the other children came back in dressed and dried off, except Mirio, who remained as naked as before.

Katsuki’s lip trembled, his face flushing a deep red as everybody’s eyes went to him in all his naked glory. It was different when everyone was swimming, it was okay then, but now he was the only one naked, except for the upbeat blond, but he liked it so he didn’t count. It was humiliating, even more so now that he knew they’d all seen his red bottom and saw him pee involuntarily.

“Your behaviour was unacceptable, Katsuki.” Izuku-sensei said, towering over the nude boy with his arms crossed, a semi-circle of boys all staring at Katsuki’s bare behind. “You’ve misbehaved three days in a row, spilling paint on Kaibara-chan, using your quirk on Eijiro-chan, now you forced Shoto-chan under the water and held him there. I’ve never had such a troublesome student before. Never.” He scolded, letting his tone be as harsh as possible. He liked Katsuki of course, the boy was beautiful and so susceptible to him, his words and his quirk.

“Yesterday I gave you a spanking on your bare bottom in private. Today, you’re getting a spanking in front of everyone, one much more severe than what you got yesterday.” He said, the little boy looking up at him, a shattered, despairing look in his eyes.

“Please no!” He begged, grabbing onto the man’s apron. “I swear, I promise I’ll be good! Please not another spanking! It still hurts really bad!” Tears started to flow down Katsuki’s cheeks, his hind-quarters trembling at the thought of an even worse spanking than he’d gotten the day before.

‘’No Katsuki. I can’t trust you anymore. You’ve been here for three days, and each day you’ve only gotten naughtier and naughtier.’’ Izuku sat down on the ornate, tall-backed reading chair and pulled the little blonde over his lap. ‘’This time I’m going to make sure you learn your lesson in front of everybody.’’

Izuku looked to Shinsou. ‘’Bring me my brush Shinsou-sensei.’’ There was no going back from this point. He loved Katsuki, but it was his job to ensure he was disciplined while he was at his daycare.

A strain of fear pulsed through Katsuki. In his short life he’d only ever been spanked with a hand and that was always more than sore enough. But a brush? He couldn’t even begin to imagine how that would feel against his tiny, unprotected bottom.

Shinso went and returned within half a minute, a broad-backed, thick wooden brush in his hand. There were seven holes drilled into the back on it, the mere sight of the implement in Shinso’s hand sending chills down Katsuki’s spine.

“Please, Izuku-sensei!” He cried, looking over his shoulder. “Please don’t!” He was close to screaming, his entire tiny body shaking. He didn’t even have the will to thrash or physically resist.

Izuku took the heavy brush in hand and clamped his arm around Katsuki’s waist so he had no chance to escape. ‘’Let this be a warning to everyone in the class. This is what happens to bad little boys.’’ He patted Katsuki’s bottom gently with the back end of the brush. He then lifted the implement over his head and brought it down with all his strength, flicking his wrist at the last moment so it struck both cheeks at once.

Katsuki screamed out loud, a surge of energy bursting through him, coaxing him to struggle and wriggle, anything to escape the blistering pain that single spank wrought onto his bare, already reddened bottom.

SMACK!

Izuku lay another fierce spank onto the naked boy’s clenched, red rear! Inciting another curdling yell from Katsuki. His heart throbbed, it really did, but he knew that if his behaviour didn’t improve, and fast, he’d have no choice but to expel Katsuki. Three days, three boys, three incidents. That could not fly, and it was his responsibility to nip that awful behaviour in the bud.

SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK! SMACK!

Every crack of the brush brought a scream from Katsuki and a terrible welt was left behind on his ass. The previous redness was quickly replaced with dark red, purplish welts that only got worse with every hard impact of the brush. Izuku did his best to even the spread of the smacks around. But he quickly ran out of room, even after he targeted Katsuki’s sit spots and thighs. So Izuku was forced to smack already welted flesh, creating blister marks from the holes in the brush.

‘’I expect you to behave now, Bakugo Katsuki. Do you understand?’’ Izuku scolded as he painted Katsuki’s flesh with blisters down to his lower thighs.

Katsuki was inconsolable. The intense, burning, hellish pain that consumed his entire ass and thighs left him incapable of taking in his sensei’s words. He sobbed and struggled, no real energy left to put into resistance. He could only lay slack over the man’s lap, taking every harsh, stinging slap of the brush, his palms sweating as they held a vice-like grip onto Izuku’s trouser leg.

He didn’t know why he did it, it was an absolutely idiotic idea, especially given the situation he had already put himself in. He only knew the pain, and he wanted out! He lit his sweaty palms, small but hot sparks singing the trouser leg. He regretted it the instant he did it, but he wasn’t able to say that, he just hurt too much!

Izuku hissed as his leg was burned with Katsuki’s quirk. ‘’Katsuki! Watch it with your quirk!’’ He landed two final smacks with the brush before setting it down. ‘’Dabi, carve a ginger plug for little Katsuki. He just made the rest of his spanking much worse.’’ Izuku harshly pinched Katsuki’s beaten cheeks. ‘’You should start apologizing to the class Katsuki.’’ Izuku started coldly.

Katsuki hiccuped and sobbed, his chest heaving, his breath short as the burn on his cheeks persisted and settled, getting worse and worse by the minute.

“S-s-s-s-sorry!” He blurted out, not able to string more than two syllables together.

Izuku knew that was all he was going to get for now. He’d make the boy apologise properly later on, before class ended. A moment later, Dabi returned, a small piece of ginger root carved into the shape of a plug in one hand. He took the root from the other man and propped up Katsuki’s hind-quarters. He forced him to spread his legs, revealing his little pink hole. He touched the tip of the root to his virgin entrance.

“I want you to think long and hard about everything you’ve done until now, Katsuki-chan.” He admonished, pushing the root in, inch by slow in inch until only the very end poked out from his hole.

Katsuki quirmed and screamed, a new type of burning festering in him now, one that grew more and more intense with every passing second. Words failed him, he could only gurgle out random syllables that flowed with the torrent of tears and snot down his face.

With the root inserted Izuku began to spank the boy with his hand knowing that every time he clenched down on the fig it would make the burning all the worse.

Katsuki quickly realised this too but as both the burnings on the inside and outside of his butt grew more and more searing he could do absolutely nothing about it except accept it, falling limp over the man’s lap as he experienced pain unlike anything he’d ever thought possible.

Minutes passed like this, the CLAP CLAP CLAP of bare hand on naked, bouncing buttock echoed over the class, all of the other children watching on in amazement as their most ill behaved peer got his rear shaded a deep, deep mahogany red, that light orange plug sticking out slightly from between his clenched cheeks. All of them now had a much healthier fear and respect for their usually jubilant, broccoli-haired sensei.

Izuku gave out twenty firm smacks with his hand before grabbing the hairbrush for a second time and using it against Katsuki’s well beaten and burning red bottom. “You will act like a good little boy from now on Katsuki. Or I will make this a daily occurance. Do. You. Understand!” Izuku gave a flurry of full power smacks with the brush. Covering his cheeks down to his little thighs. All while Katsuki’s little hole clenched and unclenched around that unforgiving root of ginger.

“YES! YES! I’LL BE G-G-G-GOOD!” Katsuki sobbed, his body writhing, his insides and outsides burning like nothing he’d ever known before. It was as if his cheeks were being pressed onto a white hot flame while his insides burned like unholy fire! It was truly the worst thing he’d ever felt in his short life.

“I PROMISE! I PROMISE, SENSEI! PLEASE! PLEASE!” He begged, his body going limp, his throat too sore to say anything else, any wilful defiance he’d had burned from him through his scarlet bottom and stinging insides.

Izuku continued the onslaught of burning pain for another five straight minutes. Punishing Katsuki even when he went completely limp.This was both a punishment to Katsuki and a warning for the rest of the class as well.

When he was finally done Izuku slowly pulled the root of ginger from between Katsuki’s bruised cheeks, put the brush down and stood the naked, sobbing boy on his trembling legs. “You will stand in that corner until I say you can leave with your hands on your head, and your nose touching the wall. Now get moving Katsuki.’’ Izuku scolded, slapping his rear to get him moving.

Katsuki let out a miserable sob as a final slap was etched into his bottom. Slowly but surely he made his way to the corner, his classmates parting for him, and stuck his nose in it, placing his hands on his head. He did not want to disobey a single letter his sensei said, not now that he knew what the man was really capable of. Even if it killed him, he would be a good little boy.

The class continued for everyone else, Izuku reverting to his typical upbeat self, but the curtain had been pulled back and no one stepped even a toe out of line.

Gathering the class together for storytime. Izuku wanted to try and bring back some sense of normalcy after what had just happened. “Mirio, how would you like to be today’s special reader? You can pick any book you like and sit on my lap and read it to the class.” Izuku offered as he gestured to the large array of children’s books he had on display.
“Of course, Sensei!” The happily nude boy said, darting over to the bookcase, passing the still sobbing Katsuki, whom he gave a sorrowful look. He picked a class favourite, “The Quirkless Boy Who Could”, and presented it to his sensei, who was already sitting cross-legged at the head of the class.

Izuku guided the naked boy onto his lap, making sure his perky little bottom sat right on top of his straining bulge. “Oooh I like this one Mirio. It’s one of my favorites.” Izuku praised him while he wrapped his arms around the boy’s middle. Mirio was by far the best reader in class, he was already reading two grades above his level. Apparently Mr. Togata put a lot of emphasis on it and Mirio was just the right kind of angel to put his heart and soul into it.

“You did very good, Mirio.” Izuku said after the boy finished the last page of the book. “Now everyone, Hokuro-sensei and Hitoshi-sensei will be in charge for naptime.” He said, standing up with Mirio in his arms.

Some of the boys groaned, others were all too happy to nap, but no one put up a fuss after what happened to Katsuki.

“Now, would you like a reward for reading so well?” He whispered into Mirio’s ear. The boy nodded, bouncing in his arms. “Very good.” He smiled, taking him into his office.

“What’s my reward gonna be, sensei?” Mirio asked as the man sat him down on his desk. Izuku hesitated to respond, choosing to lock his door first.

“You really like being naked, don’t you, Mirio?” He asked, beaming a bright smile at the boy, who was swinging his legs back and forth over the edge of the desk.

“Yup! I love it!”

“I think I’ll try it too!” Izuku announced, clapping his hands together. “Just to see if I like it too.”

Mirio beamed back at him, his cheek going a light pink.

“That’d be great!” He cheered, hopping off the desk, his little cocklet standing tall.

Izuku ruffled Mirio’s head of fluffy yellow hair. “Thank you for being such a good boy for me by the way. You’ve been nothing but an angel for me.” He said with a warm smile as he began to undress, starting with the apron, followed by his simple t-shirt.

The final articles of clothing he removed were his pants and underwear. The freckled man could see Mirio’s little eyes follow his massive cock as it bobbed in the air. The impressive seven inch member bobbed in the air. Clear drops of pre-cum shined and dropped from his tip. “Mirio, it’s naughty to stare.” He teased as kneeled onto the carpeted floor. His arms held open so Mirio could hug him.

The boy’s heart raced, he was almost short of breath. He ran into his sensei’s open embrace, wrapping his arms around his neck as he felt himself become engulfed by the man’s warmth. His hard little member stirred as he squirmed and writhed against Izuku, whose arms went down to caress and knead his soft bottom.

“You're my little angel, Mirio.” Izuku whispered while kissing his smaller lips. He held the boy tight, his member bobbing and leaking pre as he played with his soft bouncy cheeks and made out with the young boy. His tongue slipped between his lips to swipe across Mirio’s lower lip before sucking it into his mouth to gently nibble on.

“You’re just a sweet little gummy bear aren’t you Mirio? I love you so much~.’’ He whispered between passionate kisses. Eventually he was able to wiggle his tongue into his mouth and explore his little wet cavern.

Mirio went red in the face, closing his eyes in ecstasy. He’d seem grown-ups kiss all the time, they always seemed to like it. His dad said it meant they loved each other, so that must mean that his sensei loves him! He could barely contain himself!

“I love you, sensei!” He said when the man pulled back for air. Mirio then pulled him back in, pushing his own tongue into Izuku’s mouth, hoping more than anything that he was doing everything right.

Izuku moaned sweetly as he felt Mirio kiss him back. ‘The little rascal!’ Smiling from the kiss he let their tongues dance against each other. Every touch leaving a buzzing tingle behind that spread into Izuku’s very core.

With Mirio distracted from the kiss he slipped his middle finger down his ass crack to rub his virgin little butthole. The pad of his finger teased and massaged his rim. After a good minute he pulled back, his breath coming out in short pants. “Ready for your big reward Mirio, it’s going to feel really really good.” He whispered as he grabbed a bottle of lube out from his desk draw.

“Spread your legs just a little bit.” He commanded softly, slipping his member between his plush thighs. “Now squeeze them shut around my willy. Just like that.” Izuku purred as he drizzled some lube down Mirio’s butt crack. Which he helped spread and rub into his hole using his fingers.

Mirio shivered as the cold, slippery substance went between his cheeks, but he trusted his teacher more than anything else in the world and believed that he was telling the truth.

“O-okay, sensei.” He breathed, his heart pounding, his cocklet straining, his fingers trembling and his pink hole quivering. It had never been touched like that before and, while strange, it didn’t feel bad.

Mirio let out a little yip when Izuku’s finger breached the ring of muscle, slowly worming its way deeper and deeper into him. He couldn’t help but clench down in it, his arms wrapping around his sensei’s midsection as an all new feeling spread in his lower half.

Izuku only slid in half way before easing his digit back out. He wanted to take this easy and slow for Mirio who was a complete virgin. “Try to relax Mirio, it will feel really good I promise.” He whispered as he shallowly fingered his hole and fucked his thighs at the same time. With every thrust with his finger he dug in a bit deeper, a bit closer to those bundles of nerves that would feel so good to be touched and poked.

Once he felt as if Mirio had relaxed his hole enough, the freckled boy-lover slid his digit into the last knuckle and pressed down hard on Mirio’s tiny prostate.

“Oh-oh-OH!” Mirio moaned, throwing his head back, his cheeks flushed red, his nails digging harmlessly into his sensei’s skin. “S-s-s-s-sensei!” He stuttered, his breaths short and ragged. He couldn’t not push back on the man’s intruding finger as it pressed something he didn’t know he had at all. He felt his willy spasm and twitch, that wonderful feeling exploding through his body once again. And this time he didn’t even need to use his hands! “Wha-wha-what is that?” He asked, barely able to get a word out as the man continued to press down on his sweet spot.

Mirio wasn’t the only one red faced. Izuku was still sliding his cock in between his student’s soft little thighs and it was just driving him mad with lust. “It’s your prostate Mirio. It’s what all boys have inside them, it’s their feel-good spot.” Izuku murmured as he added a second finger to Mirio’s impossibly tight rectum. He twisted and curled his fingers against that special spot inside of him.

“You're going to make me cum with just your thighs, sweetie. Keep your legs tight…” Izuku murmured under his breath, his forehead slick with sweat.

“O-okay!” Mirio said, determined to make his sensei feel good too. The feeling of being stretched was brand new to him and it stung, but at the same time it felt amazing, especially when his sensei pushed down on his “prostate”. He could do that as long as he wanted and Mirio would never complain.

“S-sensei! It’s happening again!” He cried out as his cock twitched again, a shooting feeling coursing through it! Worn out, he leaned against the man’s warm body but was determined to keep his legs tight so he could slide his man-sized dick between them.

Izuku stuffed his two fingers as deep into Mirio as he could as he clung to him. His hips thrusting away at a million miles a minute. He was like a needy animal as he soaked the back of Mirio’s thighs with his shiny pre-cum. Then finally he felt it happen. The invisible rubber band inside his stomach snapped and he pulled his cock out from between his thighs and pressed it up against Mirio’s stomach.

Cum shot out and soaked Mirio’s belly and chest. The syrupy spray coating that smooth tummy like a hose. As his orgasm died down, Izuku slowly slipped his fingers out from Mirio’s backside and laid down with him on the floor of his office.

“M-Mirio...you were amazing.” Izuku whispered, his arms wrapped around Mirio’s tiny waist. Leaning in he kissed him softly.

Mirio, glad to have pleased his sensei so much, kissed back, tired and weak-limbed from all the new sensations he’d felt today. He hoped they’d get to do more in the future.

Minutes passed, the man and boy switching between soft kisses and warm cuddling, but eventually they had to stop as naptime came to an end.

Izuku sighed as he kissed Mirio one last time before sitting up. “It’s time to get ourselves cleaned up baby. We don’t want others to get suspicious.” Izuku whispered as he grabbed his box of tissues and wiped them clean of lube and cum. He was going to have to make Mirio take a shower before his dad came to pick him up.

“There, all better.” Izuku whispered as he tossed the used tissues into the trash can. Dabi would cremate the biological evidence away later. He then got dressed and presentable for the class. “C’mon Mirio, time to join your classmates.” Izuku whispered as he swatted the boy’s rump playfully.

Mirio giggled, rubbing the swatted cheek. Even his sensei’s play-spanks had a bite to them. He was glad he was his little angel, but he couldn’t deny that he was curious what a real spanking felt like. In any case, he went with the man, a bit weak in the knees but all in all very happy with this new development with his sensei. They loved each other, they kissed and made each other feel good! That was what love was after all, right?

Izuku walked into the room giving off the vibe that he’d just slept on the fluffiest cloud in the universe. He radiated such an aura of euphoria that the children almost forgot what they’d seen him do to Katsuki’s bare behind.

Speaking of, Izuku looked the other naked boy, still in the same position as he’d been in earlier, his bottom having settled into a deep red, almost purple colour. Feeling a slight pang in his chest, he decided that the boy had been punished enough.

He took a deep breath.

“Kacchan, could you come to my office, please?”
