Bakugo shucked off his pants and pulled up the briefs. "These are so thin! THANK FUCK!" He said, gleefully sighing.
Aizawa was writing something down, when he noted how raw Katsuki's skin was. "Bakugo, lay down on your bed." Shota sighed, closing the curtain. He looked at Katsuki who was laying down with his arms over his chest and tongue out, head-to-the-side, like a corpse. "Very funny." Aizawa said, flatly. "Roll over. Pull your pants down."
"Aw, man. Am I getting a spanking?! I didn't even do anything!" Bakugo said, exasperated.
"You JUST punched Todoroki in the face!" Shota replied, exasperated, too.
Katsuki rolled onto his stomach and yanked down his pants. At this point, he was not shy- his teacher had spanked him bare at least two dozen times- and this was just his butt.
Aizawa poked at his skin with the back of his pen. "You've been scratching. When?"
"Uhhhh." Bakugo thought out loud. "In, like, the shower… and whenever I can. Diaper rash fucking sucks." He said.
Shota clicked the pen closed and slid out the changing supplies. He showed Katsuki the cream that was SUPPOSED to be empty now. "Ring any bells?" He asked. "You got this BEFORE the quirk training camp. You used it then when you weren't snapping your ankle." The instructor said, popping the cap off. He took out a wipe and gave warning. "The wipe'll be cold." He said, before wiping across the boy's bottom. Aizawa put the amount of a single coin's worth in the middle of his hand. "Use this much for each cheek and twice this amount for your perineum and gentials. And Bakugo?" Shota said, wiping it off with one finger and putting it into Katsuki's hand.
"What?" The teen asked, annoyed and embarrassed.
"Never make me do this again. Take care of yourself." Aizawa frowned.
"Yeah- two things:" Bakugo began. "ONE- NEVER AGAIN- AGREED. Two- the fuck is a perineum?"
Shoto spoke up from behind the curtain. "Your taint, dude!"
"Gross." Bakugo muttered.
Todoroki laughed. Bakugo cursed him out. Recovery Girl hobbled in.
"Dude! At least my teacher didn't have to tell me how to apply cream!" Shoto belittled.
Aizawa was about to discipline Todoroki, but Shuzenji spoke in time to Shoto. "Todoroki, dear, I need to check your rash, please lower your drawers and spread your knees."
"HA!" Katsuki laughed. He waited for Aizawa to walk out of the curtained half of the room and stood to spread the ointment. The burning instantly stopped. WHY DIDN'T HE USE THIS IN THE FIRST PLACE?! He cursed at himself. Once his rash was gone, he intended to sneak out for a night with Kirishima. They had been "texting"… with great difficulty on Bakugo's end, as he was constantly clamped in a diaper. He stripped off his pull-up quickly and snapped a pic of his dick before stuffing his erection in his briefs.
When Aizawa opened the curtain back up, Katsuki was adjusting the fly of his jeans and lowering his black tank top. "Can you, um, tell?" Bakugo asked, as he waited on his side of the curtain for Recovery Girl to finish checking Shoto for a rash.
Shota looked up from his phone. "No." He said after a beat.
"You hesitated!" Katsuki panicked, looking around at his bottom.
Aizawa laughed at a text from Mic and then put his phone away. "You're fine. I wasn't paying attention. All Might is coming soon." He informed.
Like clockwork, Toshinori appeared, and opened the curtain, to reveal Todoroki tucking in his shirt into his pants. Shuzenji threw away a pair of gloves and handed him a gummy medication.
"Shall we? It's just an intake today, no EMDR." All Might said. "Cab is waiting."
Bakugo sat and looked out the window the whole way to the Tokyo Trauma Institute, which was actually not as far as Tokyo, because it was located *just* outside.
The cab left to park, and Katsuki entered the hospital portion of the complex at Yagi's urging, as the instructor and hero had his hand on Bakugo's back. "You're alright, son." He assured.
Katsuki nodded. He waited and waited. Finally, a woman came out. "Bakugo, Katsuki?" She asked.
The teen stood and had his hands clenched to his sides. He bowed, respectfully, and walked on to get his vitals taken and looked only once behind him to see All Might reading a magazine.
"Hi, I'm Yuri." She smiled. "Today's just an intake and on Friday I'll teach you calming techniques." She said before correcting, "—Well I'll teach you more calming strategies."
She asked basic questions about his home life, school life, and growing up, all of which he answered. When he had to talk about his trauma, he locked up a little, so she had him change to learning about 'bilateral tapping', which involved Bakugo crossing his arms over his chest and tapping his collarbone one-side-at-a-time… repetitively while counting his breathing. She asked him again about his trauma and he answered: this time, better.
Before he knew it was over, it was. "See, time's up. I know you've been watching the clock." She said, meeting his nervously scanning eyes. "You dissociated a bit there at the end." She said, smiling gently. "But you remembered your breathing for most of it. I'm very impressed, Katsuki." She said. "I'll see you Friday, okay." She added, standing up. "I'm going to talk with your guardian for a moment, is that okay?" Yuri asked.
Bakugo shrugged and walked out to All Might. It was unlike him to be shy, but he met back up with Toshinori and realized that he dribbled a little bit in the pull-up. He ignored the conversation between the adults and opened the backpack to grab a small cloth pack that was essentially his diaper bag. Yagi watched his student from the corner of his eye and nodded, when Katsuki pointed his thumb over his shoulder towards the bathroom.
Inside the handicapped bathroom, Bakugo took off his shoes, pulled down his pants and stepped out of his diaper before applying cream. He was slightly sore from not being able to masturbate for a few days and could hear All Might still talking, so he used the cream to rub one out quickly and then tucked his manhood away in a fresh pull-up. He washed his hands and looked at the cream bottle. "Not the intended use, but not my worst J.O." He sighed, quietly, turning out the light and rejoining his teacher. They returned to campus and Katsuki sat on his bed in the clinic. He looked at All Might and blinked.
"Hey Sensei?" The student began.
"Yes?" All Might said, flipping through Bakugo's chart.
"May I go to the gym? Sometimes Eraserhead lets me go to the pool and swim laps."
Yagi thought. It WOULD be good for the kid to get out… he reserved silence for a second to think before agreeing and handing back Katsuki's phone. "OK. But be back in an hour or face my wrath." He said, with a chuckle.
