Babysitting
Aomine visits Kasamatsu in hopes of spending time with his boyfriend but is somehow roped into helping babysit his boyfriend's younger brothers.
Aomine planned to visit unannounced, in the high hopes of catching his boyfriend off guard and maybe getting to see him in his pajamas or casual clothing he wore at home. He expected to see the shorter teen's shocked and/or surprised face, expected to be welcomed in nonetheless just because Kasamatsu cared like that, heck, Aomine was even prepared for a smack to the side of the head, for simply showing up out of the blue, unplanned.
The last thing he expected when Kasamatsu swung the door open was to see the older boy holding a baby close to his chest with one arm while holding a bottle in the other hand, testing the heat of the milk on his wrist of his currently occupied arm, all while talking on the phone which was pressed between the side of his head and his shoulder.
Aomine blinked, not knowing what to say after vaguely wondering if he had the right house for a moment. The tanned skinned basketball player further took in Kasamatsu's appearance, finding it somewhat adorable that the other teen had something on his cheek, possibly baby food, and a piece of lettuce stuck in his hair.
Shuffling the bottle to his other hand, Kasamatsu let the phone drop and slide down his chest before he caught it and pressed the red button, ending the call. He looked up at Aomine, clearly tired and exhausted but at the same time happy and content. "What are you doing here?"
"What? Can't I visit you?"
"Yes, but… I wasn't expecting you to." Kasamatsu blinked, shifting in his stance as he tossed the phone onto the couch, taking the bottle into his free hand and placing it against the tiny baby's mouth. The baby immediately reacted and started sucking on the bottle, drinking the warmed milk. When Kasamatsu turned, it was then Aomine realized that there was a fourth person at the door, hiding behind Kasamatsu the whole time, small hands clutching the older teenager's pants and looking quite shy.
"Hey." Aomine greeted, nodding down to the small boy. Somewhere in the back of his mind, Aomine knew that these were Kasamatsu's brothers, having heard about them a few times from the third year. This, however, was the first time he has seen any of his brothers, also the first time he has seen his boyfriend handling a baby.
It was adorable.
Kasamatsu walked further into the house and Aomine followed, almost obediently. The dark haired teen sat down on the couch, next to Kasamatsu who had put the bottle of milk down and was now holding the baby with both arms, rocking him gently and humming a soft tune that Aomine was sure he heard from somewhere. The baby, his youngest brother, slowly closed his eyes, hiccupping groggily as he nuzzled into Kasamatsu's chest sleepily.
Okay. It was more than adorable.
"Have my babies." Aomine blurted out lamely, his cheeks flushing once he realized what he said, and also from the way Kasamatsu chuckled at him.
"That's impossible and you know it."
"So, if you could, you would?"
It was Kasamatsu's turn to flush, the hues of red splatted across his cheeks, "I- I didn't say that, idiot." He mumbled out in a stutter, turning his eyes away from Aomine in favor of tending to his youngest brother. The second youngest was standing in the entry way, holding onto the door frame as he peeked shyly at Aomine and Kasamatsu. Aomine stared at him and looked away, before looking back just as quickly, uttering a "Boo!" The kid made a squeaking noise and quickly disappeared behind the wall, light footsteps sounding as he ran off, probably upstairs.
"Don't scare him." Kasamatsu scoffed in an accusing tone. Aomine snorted, leaning back on the couch, making himself comfortable.
"He wasn't that scared." He stated, scratching his nose briefly before studying the baby in his boyfriend's arms. The baby appeared to have soft, peachy skin (much like Kasamatsu) and from what Aomine saw before, clear grey-blue eyes. He had short, black ruffled hair which stood upright in every direction and a cute button nose. "What's his name?" Aomine found himself asking, staring at the baby some more.
"Nao."
"Nao?"
"Well, Naoki. But Nao, for short."
"Cute."
"Mmhm." Kasamatsu smiled down at the sleeping baby until he heard a faint crashing noise. Kasamatsu cringed and stood up slowly. "I need to go check on Yuuta." He announced. Aomine made to stand as well, but Kasamatsu nudged him back down with his knee. The third year leaned down and placed the napping Naoki in Aomine's arms before Aomine could say or do anything and walked towards the door, "Watch him for a sec, okay?"
"Oka- Wait, what do I-" Kasamatsu vanished and Aomine looked down at the sleeping baby in his arms, alarmed. 'What do I do? What do I do? Wait, the kid's asleep. I should just keep still and then he won't wake up, right? Oh my god. What if he wakes up and starts crying?' Aomine's eye twitched, thinking of the various scenarios that could possibly happen. With his heart pounding, Aomine thought of another dreaded thing, '… What if he poops?'
A few minutes later, Kasamatsu came back down with who Aomine guessed was Yuuta, only to see Aomine sitting where he left him, perfectly still and with sweat trickling down the side of his face. "Uhh-" He started, only to be interrupted by Aomine.
"Take him."
"What?" Aomine motioned for Kasamatsu to take the baby, which he did, and Aomine let out a sigh of relief. "What was that about?" Kasamatsu asked, sounding amused as he smirked down at Aomine who had collapsed into the couch.
"I dunno. I thought I would drop him. Or he'd wake up and start crying. Or maybe he'd poop on me. Or puke. You know, baby things."
"And here you wanted kids." Kasamatsu teased, shaking his head as he sat back down, gently swaying Naoki in his arms once more as Yuuta came over and sat close to Kasamatsu, his thumb in his mouth. "Yuu, I told you not suck on your thumb."
The thumb came out with a pop and Yuuta giggled quietly, staring up at Kasamatsu with sparkly storm-cloud blue eyes. Kasamatsu reached over and patted the little kid's head, smiling down at him. Aomine watched the exchange and was unable to help the crack of a smile that grew on his face, thinking that Kasamatsu was a great brother and son. And boyfriend. The dark skinned first year stood up and stretched, stifling a yawn. "Should I go?" He asked, looking back at Kasamatsu.
Kasamatsu arched his eyebrow and stood up, as well. "Didn't you want to come visit me?"
"Yeah, but it appears your busy."
"Don't worry; you can help me babysit my brothers." Aomine tensed, noticing that the smile Kasamatsu gave him was the kind where he had no choice in the matter.
"O- Okay…" He agreed warily, rubbing the back of his head.
Nearly an hour later, Aomine was covered in baby vomit and powder because when he had tried to change Nao's diaper, the bottle of powder slipped from his hands and exploded on the ground, dusting everything and everyone in sight.
Naoki, of course, just giggled happily and clapped his tiny hands together while Kasamatsu gave Aomine one of his death glares, wiping the powder from his face with a cloth. Aomine just stood there, sheepishly chuckling and feeling slightly awkward. That is, until Naoki decided that then would be the perfect time to urinate. All over Aomine.
Kasamatsu noticed this and his eyes widened, grabbing a fluffy towel and tossing it over Naoki's lower half before more damage could be done. A quiet silence filled the room but it shattered the moment Naoki hiccupped and giggled, blowing raspberries. Kasamatsu bit his lip, looking away from Aomine because he did not want to laugh straight in his face.
Aomine already sensing Kasamatsu's laughter just sighed and looked over his shirt, frowning at the large wet stain in the center, "Gross." He walked out of the baby's room and into Kasamatsu's, looking for a shirt he may have left behind. Once he found his shirt and changed, the first year went into Kasamatsu's bathroom and quickly cleaned himself off of all the baby powder and left the room, closing the door behind him gently. He turned and smacked right into Kasamatsu – or rather, another Kasamatsu.
The teen in front of him appeared to still be in middle school, maybe around 14 or 15 years old. He was shorter than Aomine but somehow maybe just an inch or so taller than Kasamatsu, with hair that reminded Aomine of Kuroko's, only black, and hard metallic blue eyes. He had a glare on his face, his fingers curled into a fist.
"Who the hell're you?" He asked tensely, his voice cold and wary of Aomine.
"Uhm-"
Before Aomine could say anything else, Kasamatsu appeared out from Naoki's room, holding Naoki who was still blowing raspberries and with a fresh diaper on. Kasamatsu, however, was still covered in baby powder, "Kazuki, that's Aomine." He said, smiling at his brother.
"You mean the guy you like?" Kazuki asked in a scoff, giving Aomine a once over with a raised (and pierced) eyebrow.
Kasamatsu rolled his eyes, "Yeah." He said dryly, walking over and swatting Kazuki over the head. Kazuki grunted but shoved his hands in his pockets, marching past Aomine and purposefully shoulder-checking him. "Kazu!" Kasamatsu hissed, huffing in annoyance.
Kazuki ignored his older brother and slammed the door shut to his room. He opened it a moment later, glare still on his face, "I don't approve." He muttered briefly before re-slamming the door. Kasamatsu and Aomine stared at the door and then looked at each other.
"So… I don't think he likes me."
"Yeah."
"Gee, thanks." Aomine mumbled sarcastically, fighting the smirk from his face as he leaned towards Kasamatsu. He kissed the tip of his boyfriend's nose before moving down and connecting their lips. Aomine could hear Kasamatsu make a faint noise as he tried to pull away but Aomine only tilted his head and deepened the kiss. Kasamatsu's noise of displeasure turned into the opposite as Aomine's hands pulled him closer, and just as Aomine was about to move his hands down from the other's waist, a small hand smacking into the side of his head made him jolt back. "Ow." He huffed, staring down at Naoki who was giving him a rather ominous look. Aomine twitched, taking a step back. "He knows…" He whispered, watching as Naoki snuggled into the crook of Kasamatsu's neck, sucking on his thumb.
"What are you talking about?" Kasamatsu raised his eyebrow, looking from Aomine to Naoki, then back to Aomine.
"Are all your brothers protective of you?" Aomine asked, finally tearing his gaze from Naoki, still feigning innocence, back to Kasamatsu who was giving him a weird look.
"No?"
Aomine snorted, "Yeah, right." He said.
Just then, Kazuki came out of his room, a frown in place. "You're gross, Aomine." He stated in a matter-of-fact sort of way, making Aomine scowl in annoyance and Kasamatsu scoff in amusement. "I don't need to see or hear what you do when you're with Yukio." He added, only to be high with a flying rattle toy by the eldest Kasamatsu.
"Will you be quiet and go do your homework?" Kasamatsu asked as nicely as he could, eyes narrowed at Kazuki. His glare did not seem as bad, mostly because of the flush on his cheeks from Kazuki's previous comment.
"Maybe." Kazuki said as nonchalantly as he could, smirking when Kasamatsu sighed. "Where's Yuuta?"
"He's in his room coloring." Kasamatsu answered, moving Naoki so the baby's chest was against his chest, his head resting on Kasamatsu's shoulder. Kasamatsu rubbed Nao's back and patted it gently, making Naoki hiccup.
"That's probably useless, Yukio." Kazuki intervened, taking Naoki from the eldest Kasamatsu sibling. He held the baby close to him as he turned and smirked slyly at Aomine. "I mean, it's because Nao threw up everything he had on him." Kazuki's devilish looked melted into a soft and caring one when he looked at Naoki. "Isn't that right, Nao?" The middle-schooler asked in a cooing voice, tickling Naoki's sides which made the baby start giggling.
"If I were you, I'd take a shower when I get home." Kazuki simply said, walking past Aomine and into Yuuta's room with Naoki in his arms still.
"They really hate me, don't they?" Aomine asked when the door was closed, blocking his view of the younger siblings of his boyfriend. The dark blue haired teen turned and looked at Kasamatsu in questioning, noticing the amused expression on his face. "What?"
"They don't hate you." Kasamatsu chided, patting Aomine's head. "In fact, I think Kazuki really likes you."
"Sure."
"He does." Kasamatsu pressed, nodding. He stepped closer and kissed Aomine's cheek, "He was just testing you."
"For?"
"… You don't want to know."
I know Kasamatsu has two brothers (don't know their actual names, so I randomly named them) but I wanted to add a third just because I wanted to write about Kasacchi with a baby! And it was too adorable. I seriously couldn't stop fangirling and giggling. And Aomine with the baby was just too awesome, as well. *sighs happily*
