Monday arrived hot on the heels of Sunday. It seemed that the boys slept well. Instead of gym, they were all sent to the nurse's office, where Recovery Girl ensured no bruising had occurred. She gave them each a small tube of lidocane ointment and sent them off to class. The bell rang loudly across the campus.

"No way I'm putting that shit on. My ass is still hot to the touch." Katsuki said, unhappily shouldering his backpack. He tossed the tube into the trash.

"I dunno, Kacchan. I can't imagine sitting to be bearable without it." Izuku rebuttled.

Eijirio fetched it out of the trash bin, which had nothing but paper in it from the morning so far. "Midoriya's right." Kirishima said.

They stopped into the bathroom and took turns using the stalls. It hurt to stand. It hurt to sit even worse though, so while Shoto and Midoriya rubbed cream into their rear ends, Kaminari, Kirishima, and Bakugo waited.

"Hey Kirishima. Does my butt look that bad?" Kaminari said dropping his waistband down below his butt.

Eijirio thought about kicking his friend in the ass just because he could, but decided against it. "Yeah, it's red."

"It's nothing compared to me, though." Katsuki scoffed. "No WAY Mic hits harder than Eraserhead."

Kaminari pulled his pants up. "Yeah, um, WAY. Present Mic popped us FIFTEEN times!"

Todoroki came out of the stalls. "Well none of you got spanked by Endeavour. That's the worst."

Kirishima traded stalls with him.

Izuku came out. "Guys, the cream works. It feels kinda better?"

… At least he was hopeful.

"If my skin hasn't blistered and fallen off yet, I'm not tempting it to leave my body by putting some dumbass cream on it." Katsuki said, unzipping his fly and pissing into a urinal.

… Not so hopeful.

Kirishima came out of the stall last, zipping his fly as Bakugo washed his hands. Eijirio laughed. "Okay. Fine. You owe me 100 yen the second you can't sit anymore."

"And I get the next 100 yen." Kaminari agreed.

"Third." Todoroki joined in.

"Fourth." Midoriy announced.

Bakugo glared and punched Kirishima on the shoulder. "Fine. Then you all owe me 500 yen when I don't stand up."

"Deal." Kirishima grinned, rubbing his shoulder.

The five boys arrived late to class, but were granted an excuse. They took their seats, gingerly, and some students snickered. Some other students still milled around the classroom. Where was Eraserhead?

"That's quite enough, now." Tenya lectured.

The girls from the party wouldn't even look at the boys. They felt awful... but were more so just grateful that they didn't get caught.

Finally, their teacher came into the room. Bakugo had yet to sit.

"Seats. Now. Class bagan two minutes ago." He turned to the board and began writing. He heard the girls giggling and turned around. Bakugo was bright red in the face and couldn't sit down.

"Dude. Sit. Down!" Denki whispered.

"Are you waiting for an invitation, Mr. Bakugo?" Aizawa asked.

Katsuki glared out the window and sat down, hard, immediately feeling the burn in his bottom. Several of the punished boys winced. Now THAT was an unnessecary power move. Sure enough, as Aizawa was lecturing, Bakugo popped up and sat back down after having wriggled for several minutes.

"Cha-ching." Kirishima whispered.

Then the second.

Denki made bank.

Then Shoto.

Finally, the bell rang for lunch and the students waited to be dismissed for lunch in the cafeteria. Eraserhead held the boys back.

They assembled at the front of the room by the board, as Aizawa wrote their names down with chalk. He put a tally beneath each name.

"Three gets you a repeat."

Then he put a second under Bakugo's.

"Fuck." Katsuki muttered, staring at the ground. He was bright red again.

"What was so funny today, Kaminari?" He asked, chalk held by his name, threatening a second tally. "And you know better than to lie." He waited and then drew a second line. "Kirishima?"

Eijirio panicked. "Um, so we made a bet... on how many times Bakugo would get up."

Eraserhead frowned. He heard a knock at the door and it was his husband, Present Mic. English class was next, after lunch. "Continue, please." Aizawa instructed.

"Um, you see, Sensei, Recovery Girl gave us lidocane cream but Bakugo threw his out. We got it out of the trash can and gave it back though..."

Present Mic was listening. "So what I'm hearing is that you are still playing games and misbehaving?"

"No!" Midoriya blurted out. "Please, it's not quite that. Um..." He hesitated, wishing suddenly that he had said nothing. "I think we were just all embarrassed that we got spanked like kids and wanted to..." feel better about the whole thing."

Todoroki nodded. He hadn't said much, but figured he'd aide Midoriya. "Yeah, my Dad kinda blew his top when he found out. We're lucky, we know, that we didn't get expelled but at the same time... please know- this has been embarassing for us."

Aizawa erased the names from the board with the eraser and twirled his finger around, sigaling the boys to turn around. They each braced on the desk and got a swat with a ruler.

"Now that ends the poor behavior. Do you understand?" Aizawa said. "You are forgiven. Go get lunch."

"And you'll remember this for longer than your bottoms smart." Yamada Sensei said, arms crossed. "They're not just sore from getting your ass handed to you by your teachers. It's a mark on your soul, too. You're not bad kids. You made bad decisions. And it's not just discomfort. They're growing pains."

The boys nodded and left for lunch, hurridly.

"They're growing pains, alright." Eraserhead agreed. "A growing pain-in-the-ass."

Hizashi laughed. "Shota, love, have lunch with me. I'm tired of being serious and doing my job."

"Fine. Your office or mine?" Shota asked.

"My door handle is getting replaced. I vote yours." Present Mic said.

Eraserhead smiled. "Okay can I laugh about that now?"

Preset Mic smiled. "Of course, my love. They're pretty funny kids." Aizawa followed his husband out into the hallway and down towards the staff offices. "Funny enough, we were like them, too."

"Were not." Shota objected

"Were, too." Mic laughtd.

A heavy sigh from Eraserhead. "So you think they'll be alright?"

"I do certainly hope so. It hurts to grow up."

"Yes, growing pains indeed."

"Growing pains, indeed." Mic nodded.
