TW: Panic attack and Kaminari plays a prank on little Zuku 

____________________________________________________________________________

    “ Kaminari, this is a stupid idea. You’re going to make him cry and Bakugo and Kirishima are going to absolutely murder you.” Mina whisper-yelled. All the blonde did was scoff and offer a confident grin. Of course, he knew that if he made Midoriya cry, the boy’s caregivers would kill him. But he wasn’t going to back down. His plan was perfect and he had to execute it before he lost his chance. 

    Kaminari snuck into the little’s room, the door creaking as he closed it behind him. He tip-toed around to the edge of the bed. Izuku adjusted in his sleep, his pacifier slipping out of his mouth and onto his sheets. 

    The blonde pulled a scary rubber mask from his back pocket. He’d found it in one of the boxes in his closet while cleaning it out and instantly knew he had to scare Midoriya with it. Despite literally everyone else who’d known about it telling him not to do it, he decided he would anyway. 

    He slipped the mask on his face and took a deep breath, swallowing a laugh. In one swift motion, he ripped the blanket off of the sleeping boy and yelled ‘ boo!’ in his face. Midoriya awoke with a scream, clutching his blankie for dear life.

    Instantly, Kaminari knew he’d made a mistake. The poor little guy was shaking and sobbing uncontrollably. His breathing became ragged and he began tugging at his hair. Who knew that one of Midoriya’s anxiety triggers was jump scares? Literally everyone else in class 1-A other than Denki Kaminari. 

    “ Daddy! Papa!” He choked out, grabbing desperately at the oxygen hanging heavy in the room. Just as Kaminari tried to run out of the room, Kirishima ran in and placed a heavy hand on his chest.

     “ Not cool, dude.” That was all the redhead said to his best friend before he rushed to his little’s bedside. Kaminari ripped the mask off and turned to run out again, only to be stopped by Bakugo this time. He gulped down a breath, looking straight into the eyes of murder. Oh, he was going to get it later. 

    “ C’mere baby, it’s alright. Daddy’s got you. Breathe for me, sweetheart. Come on, you can do it.” Kirishima encouraged, cradling the boy in his arms. He’d scooped Midoriya up and set him in his lap, slowly rocking back and forth. 

    Bakugo left Kaminari to guess what would happen to him after he’d calmed Izuku down and walked to the bed, sitting next to Kirishima. Slowly, he began rubbing soft, warm, circles on the little’s back offering his own encouraging words. “ It’s alright, Zuku. You’re doing so well breathing for us, baby. Such a good boy. Does my baby want a bottle, hm?” The little perked up a little at the offer, giving a small nod. 

    Kirishima stood from the bed with the boy in his arms, picking up the discarded pacifier and placing it into Izuku’s mouth. “ Let’s go get my little boy a bottle for being so good and calming down. Katsuki, I trust you’ll take care of this?” The redhead asked, shooting a sharp glare to Kaminari who’d been standing there watching the three in awe for the past several minutes. 

    Bakugo nodded to his redheaded boyfriend and ran his fingers through Midoriya’s curly hair. “ Papa will be there in a minute, baby. You go with daddy for now, okay?” Izuku nodded, knowing his caregiver would protect him. Kirishima walked out of the room and kicked the door closed behind him. He had to go ask Momo for some noise-cancelling headphones before Bakugo could get started with Kaminari. 

    Kirishima walked to the common room, running into Mina on his way to find Momo. “ Here.” She stated, placing a pair of headphones in his hand. He was visibly confused before Mina explained the situation to him. 

    “ Yeah, I told him it was a stupid idea and that you guys would kill him but-” She was cut off by a crying Izuku. His face twisted in fear. 

    “ No, no kill Nari!” He shouted, genuine fear present in his tone. Regardless of whether or not Kaminari scared him, he was still his friend and it was his first offense after all. Before now, Denki had actually done really well with Izuku, so the little didn’t want him hurt. 

    “ No baby, papa isn’t actually going to kill Nari. He’s just going to talk to him for a little bit. With his hands.” He mumbled the last part, not wanting Izuku to hear. He slipped the headphones on the boy’s head before he could protest and walked to the kitchen to make him a bottle. 

    Usually after a panic attack, the little slips into a deeper headspace of around one to two. It often helps him calm down to have one of his caregivers feed him a warm bottle of milk while they cuddled up together under cozy blankets. Neither Kirishima nor Bakugo minded doing so, they quite enjoyed taking care of their baby and they would do whatever he needed to feel better. 

    So that’s exactly what they did. Kirishima made the little a bottle and brought him to the couch to sit down. He wrapped them both up in Izuku’s favorite little space blanket and began feeding him the bottle while a cartoon played softly on the television. 

    Kirishima gave a slight flinch with every small explosion his boyfriend made from upstairs, he was very glad that Izuku couldn’t hear them because it would not end well if he did. 

    It didn’t take long for Kaminari to come stumbling down the stairs with holes burned into his shirt and his hair in an explosive mess. Bakugo walked down behind him as if nothing had happened. It was almost comical how nonchalant he was being. 

The caregiver walked over to the couch where Izuku slept in Kirishima’s arms and kissed his head.“ I don’t think dunce face will be pranking him again anytime soon.” 💛

A/N: Okay so this one is kinda short but I found a good ending place and I didn’t want to drag it on so I just ended it here. I hope you enjoyed it, thanks for reading!
