tw: sexual and nonsexual ageplay, training pants, omorashi, hyung kink, bp
he’s a bit hesitant and scared bc he doesn’t want their maknae, who looks up to him so much, to see him any differently. but jungkook was the one who suggested it, already knowing that he’s regressed with all of the other hyungs
already, and feeling sad that “everyone’s met little joonie but me!!” so he goes to talk to seokjin, who talks to namjoon, who agrees.

jungkook completely babifies the whole entire dorm when the day finally comes, coloring books and colored pencils splayed out on the small
coffee table in front of the tv, where jungkook has personally selected different documentaries on sea creatures, and a few line cartoons that the other hyungs told him the little liked. in the kitchen, he had star and moon shaped sandwiches sitting in the fridge alongside some
chopped up fruits. he also had three sippy cups ready to go, one with juice, one with water, and one with milk just in case. the couches have the comfiest and warmest blankets and pillows, if joonie wants to lay down, and jungkook is dressed in his most Comfy Clothes that he
wouldn’t mind messing up just in case the little gets too rowdy. he officially deems himself Ready.
he was Not ready.
when little joonie comes into the living room, right after his nap, jungkook almost CRIES at how adorable the baby looks in his koya onesie, clutching one of his many stuffed ryans in one hand with the other holding onto Taehyung’s very tightly because he& #39;s SHY!!! both of them
have major bedhead, and taehyung yawns before whispering something into the little’s ear. joonie nods and they both look over at jungkook, who is rooted in his spot. “go on,” taehyung lets go of the little’s hand and gently nudging him forward with his shoulder. joonie now held
the plushie to his chest, slightly hiding his face behind its head. he looked at jungkook and then back at taehyung, pouting a bit.

“daddy not comin’?” he asked timidly, voice pitched a bit higher. taehyung smiled fondly and shook his head, cooing when joonie’s pout deepened.
“you’re gonna have a play date with kookie, remember, bub?” namjoon pursed his lips in thought before nodding.

“joo ‘members.” he turned towards jungkook, who waved with a lopsided smile. namjoon waves back, and then makes his ryan stuffy wave as well.

jungkook wants to cry.
“he had lunch before his nap,” taehyung is talking to jungkook now. “but he may want a snack soon. he usually has some chopped up fruits and water at this time, but if he wants juice, his favorite is-“

“apple!!” jungkook finishes, causing to taehyung to smile proudly.
“alright, well i’m gonna go get dressed and meet the other hyungs at the studio.” he turns to leave, but namjoon whines loudly in protest. “oh! how could i forget?”

taehyung goes back to namjoon and runs his fingers through his hair. the little practically purs, closing his eyes
and smiling contentedly. he gently tugged joonie down so that he could place a gentle kiss on his forehead. “be a good boy and play nice, okay?” he gets another kiss on the nose.

“‘kay, daddy!” joonie says obediently. taehyung smiles and kisses him again, on the lips this time.
jungkook stands and watches as the two practically make out. from the looks, taehyung’s doing most of the work while joonie just lets him lick into his mouth and nibble on his lips.

when taehyung pulls away, there’s a trail of spit in between them, which causes joonie to giggle.
jungkook blinks, eyes wide and dick chubbing up just a bit. taehyung looks at him with a knowing smirk and winks before turning to finally make his leave.

“have fun, boys!!!”
