All Might was watching Shoto take down targets.

"Good day, Yagi." Hizashi greeted, antisocial husband in tow. "Shota and I came to check on Todoroki."

The student in question was shirtless and slick with sweat. Aizawa stepped forwards as the boy swayed on his feet, exhausted.

"Enough. Go back to the clinic. Dinner's waiting for you." The teacher ordered.

Todoroki was not allowed to walk on campus, alone. He was a flight risk, so Toshinori walked him.

"Hey, All Might." Shoto began.

"Yes, Young Todoroki." The man responded.

"Can I ever be a Symbol of Peace?" Shoto asked, walking into the clinic. There was a prepared meal on his bedside table.

"Of course you can. Anyone has the potential. You show great promise, Young Todoroki."

All Might checked in on the other side of the curtain, awakening Katsuki.

"Wha—AH!" Bakugo panicked. "God! Don't just come over here, Sensei!"

Shoto leaned over to see from his bed what the matter was. "You're the Symbol of Piss." Todoroki joked, seeing that Katsuki never did remember to put on his pull-ups.

"Did you have a nightmare?" Toshinori asked his student.

Bakugo screamed "No!" And then lowered his voice down. "I just… spilled some water. On myself. On accident." He looked at All Might. "Don't tell Eraser- please. Now, can you leave?"

"Don't tell Eraser, WHAT?" Came a voice.

"Dah! Eraserhead!" Katsuki squirmed.

Sensing it was not his job, Toshinori walked back to the other side of the curtain and talked with Shoto to keep him occupied.

"You don't get to tease people." The great hero lectured. He sighed. "Bare your bottom. Three of the best."

Todoroki frowned. "I won't do it again, All Might. I'm sorry."

But the boy made no move to pull down his pants.

Toshinori took a seat beside the boy, after taking away his soba and placing it back on the side table before he yanked the boy over his lap and pulled down a now-thrashing-Shoto's pants and briefs.

THWACK! THWACK! THWACK!

"No rubbing." He said, before sliding Todoroki off onto his bed, on his bottom. Shoto JUMPED up immediately as the sore skin took his weight on the bed. He hurriedly took his briefs off and slipped his gym shorts off before rubbing out the sting. He didn't care WHAT All Might said- he just HAD to!

"Two for rubbing. Grab your ankles, Young Todoroki." Yagi sighed, heavily. He popped the boy twice and left him to eat while Eraserhead dealt with a very angry and somewhat sleepy Bakugo.

Aizawa grabbed the briefs from earlier and stretched them out. "Tell me the truth." He warned, pointing a finger. "Did you sleep without your diaper?"

Bakugo strangely did as he was told. "I had a bad memory and pissed myself. I didn't even TAKE a nap!" He hissed.

"Go bring me your laundry basket." Shota ordered. "Put these linens in and which drawer is your underwear drawer?"

"Top." Katsuki muttered.

Aizawa took out Bakugo's underwear and, while Katsuki expected him to be handed a pair, the lot of them were taken and placed into the basket.

"This is the ONLY time I'm doing your laundry." Aizawa said. "You're staying in the briefs until the council says so. You are grounded tomorrow except you're NOT missing therapy."

"But-!" Bakugo began angilry.

"And I'll take the bottoms you're wearing now." Shota said, engaging his erasure quirk.

"And who the fuck is on the "council"? HUH?!" Katsuki began to stalk, angrily towards his teacher, who calmly sat the basket down.

"Little boy- you can not take on a pro. Change into briefs and pajamas, eat your dinner, brush your teeth, and go to BED. I will see you in the morning. I am NOT giving in to your qualms." Aizawa ordered, before turning his head. "And Todoroki?"

"Yes, sir?" Shoto asked from behind the curtain.

"If you ever say a cruel nickname to your peers again, I will personally paddle you." Eraserhead threatened.

Todoroki swallowed. "Yes, sir."

"Apologize." The instructor ordered, before disappearing.

The boys went to bed.

The next day, during therapy, a note was passed around. Bakugo rolled his eyes at it.

To the BOYZ:
Does Size Matter to a Mate?
VOTE YES [ ]
VOTE NO [ ]

"This is childish." He said, looking at Kirishima.

"Ha! Scared, Bakugo? I'm doing it." Eijiro smirked.

"Count me out." Midoriya said. "I agree with Kacchan."

"It's just a check mark." Kaminari laughed.

"What does it saaaaaaaaaay?" Ashido asked, leaning in against Bakugo. He wanted to push her off. SO. Badly.

He did.

"Boo, you're no fun, Bakugo." Mina said, frowning.

"I bet it's something stupid." Jiro said, doing the assignment in her notebook. "Midnight will be back in a minute."

"Flip it over—" Denki whispered.

On the other side, was a running tally and dumb interjections with signatures. It had some-er- all of the boy's information. DAMN BEING GROUNDED TODAY! Bakugo thought.

He excused himself for the bathroom and went to a urinal and walked into a stall. He was mortified that he was in a pull-up and couldn't just access his penis through the fly. He sighed and pulled down his pants and the pull-up to piss into the toilet, while praying no one would come in.

Katsuki washed his hands after kicking the handle on the toilet and remembered the note and Denki's words: Flip it over.

Y.A.- IN the opinion of moi? OUI! But I'm almost
15 centimeters, so it doesn't matter.

M.O- Who cares when you've got
a whole TAIL! Also Yuga- T.M.I.

K.K.- Ducks have corkscrew penises!

H.S.- Yooo 15 centimeters? I'm 16cm!

M.M.- Well, technically, I have the
biggest penis, proportionally.

D.K.- I'm 14 cm! Jiro doesn't mind ;)

E.K.- Therapy group just got interesting.
My quirk makes me GROW. Try 18 cm on for size!

F.T..- Yall better not let the class
prezzies see this, dumbasses.

In a puff of smoke, Bakugo burned the paper and then stomped the ashes out with his foot. He did not get up again to throw it out because he was stuck in a pull-up and getting around with no one noticing was a challenge in itself.

Kirishima and Kaminari whined that their fun was OVER. Midnight appeared.

"I was watching you all on the screen while I ran my errand. Do you mind telling me what was on that piece of paper?" Kayama asked, standing over Bakugo.

He looked up and swallowed, suddenly nervous. The ONLY good thing about the diaper was that it hid his erection from reading about Kirishima's dick size. Katsuki swallowed.

"It was just a love letter. From a classmate in 1-B. I'm sorry it was distracting." Bakugo lied.

Nemuri finished the group's activities for the day and dismissed the boys.

Katsuki waited for everyone to leave before he got up and waddled as little as possible back to the clinic.

"You can't tell, you know." Todoroki said, honestly. "You're in briefs, which are slightly different from diapers."

Bakugo was now still horny AND annoyed. He looked at Shoto. "Well I have an idea. I'm not wearing them anymore. I'm gonna burn the pack." He said.

"Dude." Todoroki said, looking serious. "You're gonna get a HUGE spanking. Mic might paddle you again."

Katsuki smirked. "He can't." he explained. "That's too many spankings. I've met my quota and since the school is responsible for my kidnapping, they get to deal with a little post-trauma rebellion."

"You're an idiot." Shoto rolled his eyes. "But whatever. I told you so."

Meanwhile, night began to fall and Uraraka was planning to sneak into Midoriya's room.

"This is it." She told herself, looking in the mirror. "Tonight- we go to third base."

Shota Aizawa had patrolled the dorms building. Everyone was where they were supposed to be…it was strange that all of the kids behaved. Something had to not be right.

"Bakugo." The instructor suddenly said to his lover.

"What?" Mic asked.

"Check the monitor. I have a sixth sense for bullshit." Eraserhead said, annoyed. He was going to do a rare patrol of hero work, but he couldn't until he knew everyone was safe at school. He treated the kids as if they were his own.

Five minutes later, Aizawa and Yamada were in the clinic.

"You burned them." Aizawa said, stalking with so much obvious anger towards Katsuki that the teen became frightened, internally.

"Yeah, so?" Bakugo said, smugly.

Shoto got up and left the clinic. Midnight was there to intervene.

"I'm getting anxious—" Shoto shrugged. "I think Bakugo is getting a BAD spanking."

"If only that were his punishment." Nemuri sighed. She looked at Shoto. "C'mon. Brief up- you're going to stay in the spare room on the first floor tonight. Bakugo is in BIG trouble."

After a thirty minute lecture and an expectation of an eight page essay on "impulsivity and fire safety," Bakugo was given the final slam-dunk of punishment.

"You're in diapers then." Aizawa said.

"I think you know I burned them." Bakugo said smugly.

"No." Shota said, annoyed, while waiting on his husband to slide in a heavy box. "You're in diapers now. NOT pull-ups. Taped in. Secure. And you will be changed by Recovery Girl OR staff ONLY if you dick around again."

Katsuki's smirk faded. "Wait- hold on. I can't FIGHT or show my face in school if I—wait—" He began to nearly hyperventilate. The anxiety he now felt was enough to make him urinate from fear: and urinate, he did.

"You're outta combat classes. You have earned yourself this punishment. And when your skin is better- you have earned a spanking. NOW—" Aizawa paused. "To review. You WILL change into your diapers morning and night and any time necessary. If you don't—the first option that you lose is changing them yourself. You will have Recovery Girl change you. IF FOR ANY REASON you mess with them, there is a product called plastic pants. You will wear them over your diaper and staff will lock them. You may choose to use a school laptop to virtually join class this week, as per your punishment, but you WILL be in therapy, in person. Am I UNDERSTOOD?" Aizawa asked, sternly.

A meek nod came from Bakugo and Aizawa handed him a diaper. Full padding.

"I can tell you need a change. I'm sorry you are so scared but on the other hand it is WISE of you to be afraid. I will NOT tolerate any more bullshit behavior from you. You WILL return to being a good student."

With great upset, Katsuki changed into his diaper, making sure to add powder for once. He wanted to cry, but didn't.

Worst night ever. He thought.

Ochaco looked in the mirror, back in her dorm. "Okay- here goes. Best night ever, here I come."
