____________________________________________________________________________

Aoyama woke up not feeling so well today. He'd had some challenging quirk-strengthening training the day prior and was still recovering. Usually, on days like this, he regressed and pampered himself. A queen deserves only the best, of course. However, he didn't have that luxury today. He had one of his most important midterms scheduled for his second-period class and was doing his best to push himself to go. As much as he didn't want to take it, he'd rather just do it and get it over with than have to come in another time to make it up.

Truthfully, he was already slipping. But he was determined to stay big and get the test done, even if he had to leave right after. He was a big boy, he could do it! He decided he'd do himself a favor and text his caregiver in advance so he could make extra sure that he would get to be little afterward. Quickly, he typed out a message asking Iida, his papa, if he could be small after class today. He made sure to mention how sore his tummy was and how he hadn't been small all week. He needed it. Of course, Iida approved and came up with a plan to make sure they could get away early.

The little smiled at his phone, excited to regress later in the day. But first, he had to get through his classes. Iida promised that he'd talk to Aizawa prior to the test and make sure it was ok for them to leave. Every other class they had that day was studying and going over past material for their next coming midterms so they wouldn't be missing much. The caregiver also decided to get dressed quicker than usual so he could head over to Aoyama's dorm to help him. It was significantly more difficult to get himself dressed when he was so sore.

Iida knocked on the door and Aoyama wobbled over to open it using his desk chair and walls for support. " Hi bubba," the caregiver said before noticing his paling face and shaky hands. " Oh, sweetie, your tummy must really be hurting you. Are you sure you can make it through class today? We can always talk to Sensai and set up another time to take it." Aoyama shook his head, he was not about to miss this test.

" N-no, I can do it. I really don't wanna...reschedule." he was struggling to talk now, pausing to take extra breaths. Iida was hesitant but understood. He knew how much he'd hate to have to make it up so he respected his partner's choice and continued on helping him out.

" Ok baby, let's get you dressed then. Here, you sit on the bed and I'll get your things." the blond nodded and sat down, he watched as his caregiver went around the room grabbing his clothes for the day and packing his bag. He liked that Iida knew where everything was and how he liked it organized. It made him feel so loved and important.

Iida finished packing his bag and brought his clothes over to him. " Arms up," Aoyama complied, lifting his arms for his partner to dress him. It felt so nice, Iida was so gentle with him. " Good boy, now for the pants." the little smiled at the praise and let Iida maneuver him so he was standing but using Iida's shoulders for support.

Once Aoyama was all dressed, they headed to their class a few minutes early to talk to Aizawa. He was well aware of the strain the boy put on himself the day prior and was supportive of them leaving early, as long as their work was finished. Now all he had to do was get through his test. He just had to make it through second period and then he and his papa would be home together watching studio ghibli movies and cuddling.

...

First period was a study hall so mostly everyone used it to prepare for the test. That did not include the majority of the Baku squad. Kirishima and Kaminari just played a few rounds of cards, they were adamant about the fact that they were prepared. They'd apparently studied all week. That was hard to believe though, considering they'd been goofing off during any free time they had.

" Hey, Yama! You think you're ready for this test?" Kirishima asked, throwing his arm over the blond's shoulder. He winced a little at the action but nodded. " I think so, I've been studying for a while. Do you think you're ready?" the redhead also nodded, removing his arm to hold up two, very confident, thumb's up. Aoyama smiled and returned the gesture, giving his friend a kiss on the cheek for good luck. He did this for all of his friends. Iida didn't mind it, he thought it to be quite adorable, actually. He appreciated how supportive his partner was, it was one of many things he loved about him.

Just before Iida sat down to prepare, he walked over to his partner's desk and had a short, hushed conversation with him. " Are you sure you're gonna be ok?" he asked, worried about his little. The blond smiled and nodded, he was going to finish this test today, no matter what. Otherwise, he wouldn't fully be able to relax and regress later.

" Mhm! My tummy still hurts lots but I can do it! I'm ready," he replied, confident in his knowledge of the subject they'd be tested over. Iida smiled and kissed him on the head. He walked back over to his desk and sat down just as his test was placed on it. He too had studied long and hard. He would pass it with flying colors.

...

About halfway into the test, Aoyama's stomach began to turn. His support belt was only making it worse, putting pressure on his cramping muscles. He looked at his caregiver who was staring very intently at his paper. Obviously, disturbing him wasn't an option. So, instead, he raised his hand and excused himself to the restroom.

...

After splashing some cold water on his face and saying some encouraging words to himself in the mirror, he made his way back to class and finished his test. It didn't take long, the whole thing was multiple-choice questions that he knew the answer to. He turned in his paper and waited patiently at his desk for his caregiver to be finished. It took an extra long time since he had to triple-check his answers and make sure he hadn't made any careless mistakes.

Iida eventually walked to Aizawa's desk to turn in his test and then back to his desk to pack up. Aoyama did the same, excited to leave class. The caregiver grabbed his bag and walked to Aoyama's desk to take his as well. He wanted to make sure that his little boy didn't put any more unnecessary strain on his body.

Quietly, they left the classroom and began the walk back to the dorms. " Papa, my tummy hurt," he whined, gripping his caregiver's hand a little tighter. Iida gave his little's hand a reassuring squeeze, " I know it does, baby. We're almost home, then you can take some medicine and we can cuddle. Sound good?" that sounded more than good. Aoyama was definitely in need of some good cuddles.

...

Iida used his spare key to unlock Aoyama's dorm and let the little go in first. He went straight to his bed and found his favorite stuffie and paci that he'd left in his bed from the night before. " Alright, my prince, let's get you out of those big boy clothes. Then we'll get you some medicine and a snack." Aoyama nodded and waited in his bed for his caregiver to bring him his fuzziest pajamas and his fluffiest socks.

" Here we go, only the best for my baby boy." Iida kissed Aoyama's head and began helping him get dressed. " There, that's much better, huh pup?" the blond nodded. He was feeling rather small and was struggling to communicate verbally.

Iida smiled and walked to the bathroom to find some medicine. He also made sure he went to the treat basket that was hidden in one of the blond's dresser drawers and grabbed a few pieces of candy. The medicine he had to take was liquid so he always gave him a treat after.

Aoyama took the medicine without a fuss, excited for his candy. Iida, of course, praised him and got the both of them settled into bed. He laid behind the boy so he could give him gentle tummy rubs and extra kisses. Aoyama always said that helped him feel better.

" Go to sleep, sugar, you'll feel better when you wake up." with that, the little blond boy allowed himself to drift off to sleep in the comfort of his papa's arms. Iida kissed his head and closed his eyes to sleep as well. He definitely hated when his little was hurting, but he'd never get tired of falling asleep like this. 💛

A/N: Wow, look at me go. Writing an entire chapter in one session, so proud of myself. Anyways, hope you enjoyed!
