Work Text:
Jimin felt blessed that he had someone like Jungkook in his life. They first met four years ago, roommates in freshmen year of college (Jimin had done his military service the second he graduated high school, so even though he was two years older than Jungkook, they had entered university at the same time). The two of them quickly become close. Away from Busan and their families for the first time, they both latched onto each other for comfort. Listening to Jungkook’s satoori when he was especially homesick always lessened the pain immensely, and the same went for the younger. Sometimes Jungkook needed a little bit of home and Jimin was right there for him whenever he needed.
They went from acquaintances to friends to best friends to lovers naturally over the next few years as they finished up college, but Jimin kept something very important from his younger boyfriend all that time.
Overwhelmed with the weight of his secret on his shoulders, Jimin finally admitted to Jungkook that he was a little just before the two of them decided to move into an apartment together.
Though the younger was a bit surprised by the admission, he actually knew what littlespace was and immediately accepted Jimin with open arms. Jimin couldn’t have been more relieved.
Jungkook became his hyung’s caregiver when he went into littlespace and he couldn’t say it was a burden when he absolutely loved taking care of the older. He had a huge soft spot for the little, especially when Jimin slipped into babyspace, which wasn’t often - only once a month or so. There was just something about Jimin becoming so little he couldn’t even speak, something about the brightness that shined in his wide eyes. He depended on Jungkook even more than normal and the younger enjoyed the responsibility. Baby Jimin was the most cuddly person in the world (Jungkook swore it) and was honestly just too adorable for words.
Just like now.
The two of them were curled up on their shared bed, the older settled snugly on his younger boyfriend’s lap as they watched Pororo on Jungkook’s laptop. Jimin giggled behind his bright blue pacifier every once in a while, but he hadn’t said a word in at least twenty minutes.
Jimin had actually just been in littlespace, but it became obvious to Jungkook that he regressed even more as he watched the little penguin on the screen with his friends. Normally, little Jimin liked to point out things to his Daddy, liked to talk at least a bit, so going completely quiet was the main sign of him slipping into babyspace.
Jungkook tried to hide his excited grin as he took in his baby’s glazed-over eyes staring unwaveringly at the bright colors on the laptop screen. He tightened his arms around the little’s waist and nuzzled into his hair.
Jimin made a sound, hands dropping where they had gripped the blanket draped over them to grab at his Daddy’s strong arms around his stomach. Mindlessly, the little grabbed onto one of Jungkook’s hands and began fiddling with his long fingers.
That was one of the things Jungkook loved - that Jimin’s hands were really quite small and looked infinitely smaller next to his own veiny, big hands. Jungkook didn’t even necessarily have what would be considered big hands, but when compared to Jimin’s they were definitely larger.
As the episode of Pororo came to a close, Jungkook began shifting his baby around in his lap so he could face him. Jimin looked up at him with stars in his eyes and damn, Jungkook couldn’t believe this wonderful man - boy, baby - was his.
“It’s getting late, baby,” Jungkook announced, even though he knew Jimin probably wouldn’t understand him. “Daddy’s gonna get you all ready for bed, okay?”
The little only giggled and wrapped his short arms around Jungkook’s neck, legs tightening where they had fallen on either side of his Daddy’s hips.
Jungkook chuckled and hitched him up as he stood, making his way through their apartment and into their bathroom. It wasn’t very big, but it was enough for them.
Jungkook’s muscles always came in handy in times like this when he couldn’t set his baby down. With Jimin on his hip, one hand safely under the little’s thighs, the other arm maneuvered around to do different tasks. First, he ran the bathwater, checking to make sure that the temperature wasn’t too hot before he began picking out a few of the little’s bath toys from under the sink. He put in a little bubble bath, just to enough to create a few bubbles and give off a nice smell, but not enough to hurt Jimin’s eyes were he to accidentally splash water on them (which Jungkook knew from experience was likely to happen).
Jimin was pliant as his Daddy set him down on the covered toilet seat and began unbuttoning his green dinosaur onesie, allowing him to get it off without much of a fight. The little giggled when Jungkook blew raspberries on his bare stomach. Jungkook grinned at the sound of his baby’s adorable squeaky laugh. He took off the diaper strapped around Jimin’s waist and tossed it into the garbage after folding it up.
Now completely naked, Jungkook lifted the little up and deposited him in the nearly full bathtub. He yelped in surprise at the feeling of the warm water before he settled in. He eagerly grabbed a toy boat from the water and began splashing it in and out, causing bathwater to go flying everywhere.
“No, baby,” Jungkook admonished gently, a hand softly on the little’s wrists to stop his movements. “That’s too much splashing, Jiminie. You need to be gentle.”
Thankfully, Jimin seemed to understand what he was saying and didn’t splash so much water out of the tub. He was so enraptured by the little toy boat that he didn’t even notice his Daddy washing his body and hair. Jungkook wasn’t complaining though, it was nice to sometimes have an easy bath time experience as it wasn’t often like that.
It took a little coaxing to get Jimin out of the bath when it was time, as he was just having so much fun, babbling away unintelligible words, but eventually, Jungkook managed to get him out of the tub and bundled into a soft towel.
After placing Jimin on their bed, Jungkook turned to the dresser, “What onesie should we go for today?” he asked, mostly to himself. “Ah! How about...a puppy, just for my puppy.” He brandished a soft tan-colored onesie with cute dog features on the hood and a tail hanging from the back.
The second the little baby saw it, his eyes widened in excitement and then he squealed, clapping his hands together clumsily.
Jungkook chuckled before closing the closet door and returning to the bed to slip his baby into the new outfit. Once he was finished, diaper also in place, he pressed a kiss to Jimin’s cute little nose and ruffled his mostly dry hair.
Jimin watched as his Daddy turned away from him to get himself some sweatpants, tossing them on quickly with an old white t-shirt on top. Jungkook returned once more, this time with a small, brightly colored rattle. The little accepted it happily and immediately began to shake it around.
“I’m gonna go get you a bottle, love,” his Daddy said, unable to fight the urge to give the little a forehead kiss before leaving the room.
When he came back, he had a freshly warmed bottle of milk with a hint of honey drizzled in - just how his baby liked it.
Jungkook settled himself against the headboard of the bed and shuffled Jimin around so he was lying across his lap, just like one would do when they were going to feed an actual baby. The little spotted the bottle and almost immediately opened his mouth, reaching up to grab onto the sides of the bottle with both hands. His Daddy still kept a firm hold on the object still, not wanting it to accidentally fall.
Jimin suckled at the teat, satisfied with the warm, slightly sweet milk on his tongue. His eyes drooped closed of their own accord as the bottle slowly emptied over the following minutes.
Once he was finished, Jungkook maneuvered the little around so they were hugging, Jimin’s chin hooked over his shoulder. Jungkook patted the older’s upper back gently, going through the motions of burping even if Jimin technically didn’t need it. He knew that it was something that calmed his hyung even further in his headspace and it felt natural to do it.
A few minutes later, the two of them laid snuggled together, limbs intertwined under the warmth of the blanket.
Jungkook gave the little’s nose a kiss, “Goodnight, my little prince.”
Jimin smiled behind his newly acquired pacifier before he fell into a deep sleep, where he dreamt of puppies and bunnies hopping around in a field of bright flowers together.
