Chapter Text
Jungkook had never felt this kind of urge before.
He wasn’t… the omega people expected him to be when he presented. He joined Big Hit when he was only 13 years old, and being the maknae of BTS basically meant being babied through everything; when he presented as omega at the age of 15, it only made them even more protective of him. He could trust his hyungs to take care of him at all times, help and comfort him when he needed, cheer for him at school. Maybe he enjoyed it too much.
People expected their dynamics to change over time, and they did. They all grew up, Jungkook especially, became more mature and aware of his instincts, but also of his own personality. He took care of the members as much as they did, but he grew taller than most alphas in their small pack, and bulkier, due to his love for working out. He hadn’t shown strong nurturing instincts yet and didn’t really think about kids or a big family—as much as he knew Jimin wanted them, they weren’t even allowed to mate officially. They belonged to each other, had discussed it more than once with the other members and their managers, but the career came first.
Jungkook hadn’t shown strong nurturing instincts until that night. Another night of work, even if it didn’t look like it for most people. He had been rehearsing his cover for Oh Holy Night for a long time, Jimin and Namjoon would sing Santa Claus is Coming to Town, Taehyung and Yoongi prepared Jingle Bell Rock, and Jin and Hoseok worked hard to perform Feliz Navidad. They had a beautiful replica of Santa Claus’ sleigh, a candy shop, huge gift boxes and candy canes, all set for a magical performance.
Then the staff came guiding a little girl to the stage by the hand, showing her around and making sure she wasn’t nervous. He knew they’d have a young actress with them, but something clicked inside him when he saw her. Jimin and Taehyung instantly rushed over to her, asking her name—Choo Sarang—and taking care of her. Jungkook found himself being pulled towards them like a magnet, and the girl seemed to like him as well.
All the members seemed enchanted during the rehearsals and the presentation night. Jungkook led Sarang by the hand through the stage, between songs, and made sure she felt comfortable. He brushed his fingers lightly on her hair, fixing the bow on the back of her head and her long black curls. She looked like a little angel in her pretty white dress, and seemed so at ease on the stage, around the members.
As they approached the stage for Santa Claus is Coming to Town, he knew Jimin couldn’t take his eyes off them. Jungkook felt his gaze on them even when his head was down, looking at Sarang while they walked. He looked up and Jimin had the biggest smile on his lips, his heart ached from the adoration coming from Jimin.
But nothing could have prepared him for when Jimin picked the girl up, swirling her around and laughing under the bright spotlights. Sarang threw her arms over his shoulders and leaned towards him for a moment, as if she was going to touch her forehead with his. Jungkook felt like he was having a vision, Jimin with their daughter dancing in the yard to one of their songs, the warm summer sun washing over them, their daughter’s dress moving with the wind and her dad’s steps.
It was a split second, Jungkook realized as Namjoon rushed past him to get to his position, Jimin letting go of Sarang but still holding her hand, yet he felt so sure of his vision, he’d do whatever it took to make it happen.
“Kook, did you forget to apply the scent masker?” Jimin whispered, looking around with a worried expression.
They were together on the stage, all the other groups around them for the wrapping up of the event. Little Sarang had been waving at them from backstage a minute before, looking so happy. Jungkook had waved back, his smile so wide his cheeks actually hurt.
“Noonas would never let me forget. What’s the problem?” He whispered back, feeling deeply at ease. That night had been nothing short of amazing.
“Your scent is so strong.” Jungkook couldn’t tell, that many people around him, but Jimin could smell him meters away. “I think you’re releasing pheromones.”
Jungkook’s eyes opened wide, genuinely surprised and now worried too. He couldn’t think of a reason for it to happen—of course he was excited to be there, but it surely wasn’t enough for him to release pheromones.
He shrugged it off, smiling again. “It’s okay, hyung, it’s almost ending. Then we’ll go home.”
The most he could do to soothe him, in front of all those people, was rub a hand down Jimin’s back. It seemed to work, but it didn’t stop him from snarling at another idol on the back of the stage, who had been looking towards them. Jimin knew the warm smell of cranberries and peaches was alluring, but that boy belonged to him. Jungkook giggled, probably releasing even more pheromones.
Jungkook insisted all the ride back to the dorm for Jimin to sleep in his room that night, Jimin ended up agreeing. How could he possibly resist him?
The younger stepped out of the shower sighing dreamily, not even bothering to put on clothes before plopping down next to Jimin on the bed, the towel around his hips threatening to fall.
“I can’t stop thinking about Sarangie. She’s so pretty, hyung.”
Jimin smiled, the thought of the little girl warming his heart. “Yeah, she is-”
“And she’s so small, but so smart. She did all that performance with us and even though she must have been exhausted, she was smiling so much. And she got everything right, I’m… I’m in love, hyung.”
“I can see that.” Jimin laughed, petting Jungkook’s hair. He’d laid his head on Jimin’s chest, whole body wrapped around him. “You never say stuff like this, are you having baby fever?”
Jungkook connected some dots in his mind. It all made so much sense now that he came to think of it. The awe he felt when seeing Sarang, the way her tiny hands fit in his, her beautiful smile when Jimin picked her up… Jimin’s beautiful smile, the way his heart felt close to exploding. The pheromones.
“Hmm… actually, I think I am.” All the images were already formed in his head, their little family. “I really want one. A baby. Ours.”
Jimin cleared his throat, body stiffening a bit. His hands cupped Jungkook’s cheeks, pulling him up to look into his eyes. “Kookie… you know we can’t. Not right now.”
“But imagine it, we’d get to take our pup to such amazing places around the world, the members would love it.” Jungkook raised a hand to trace the lines of Jimin’s features fondly. “And the pup would have hyung’s button nose and pretty lips, your cute little hands. Don’t you want that?”
Jungkook’s eyes sparkled so bright, Jimin had never seen him so passionate about having kids before. He loved the idea so much, but they couldn’t afford to fuel those dreams for now.
“Ah, Kookie, don’t do that to me. You know it’s what I want most in the world—to finally mate you and start our family, see how pretty your belly would look with my pups in there, then have a lot of them running around. The boys would make such good uncles, Tae would shine brighter than the sun- no, no.” Jimin shook his head vigorously, his chin brushing against the hairs on the top of Jungkook’s head, rested on his chest again. “You can’t do this to me. We’re not supposed to have kids at our age, we’re idols, remember?”
“Yeah, but you do want it.”
Jungkook was so determined when he really wanted something.
“Of course I want it. I think about that all the time, I’ve dreamed about it, I can’t wait for-”
“Then let’s make one.”
Jimin blinked in astonishment. Was he serious?
“What?”
“Let’s make a baby, hyung. Why wait?”
He couldn’t be. Jimin pushed Jungkook by the shoulders, motioning for both of them to sit up.
“Because the company would fucking gut us, Jungkook. Also, we’re both on suppressants, you’re on birth control. It’s nearly impossible.”
“Nearly… and I didn’t take my meds tonight.”
Jungkook looked so young under the dim glow of the lamps, huge eyes and a trace of a hopeful smile on his lips. It’s a baby, Jimin thought, a baby who wants to have babies.
“That’s not how the meds work, love. You really should take them now, though.” If their managers found out he skipped the meds, both of them were in big trouble.
“Aish hyung, you’re no fun at all.” Jungkook pouted and rolled away from Jimin, laying closer to the edge of the mattress. “I just wanted you to knot me and give me your pups.”
Jimin smiled fondly and rolled over to him, big spooning him and sucking a light bruise right on Jungkook’s scent gland, making him shiver. “I can give you the knot, you should’ve just asked. It’s yours anyway.” Jungkook smiled at the reassurance, trying to make his large figure small in Jimin’s arms, although he already felt completely safe. “But I can’t give you the pups, sorry.”
Jungkook sighed, still lost in his daydream. Jimin wondered if he was thinking about his belly, round and soft, their pup kicking into Jimin’s palm, cupped against the smooth skin. If he was thinking about how beautiful their pup would be, fluffy black hair falling over big doe eyes, just like Jungkook’s, round cheeks, rosy and healthy.
God, he wanted it so much. He knew they couldn’t, but the try was absolutely worthy.
“I’m going to pump you up with so much cum that you’ll just have to get pregnant.”
Jungkook loved the change in Jimin’s tone, body already heating up from the change in his scent, filled with desire. He twisted his body towards the older, catching his mouth in a passionate, desperate kiss. The fit of their mouths together was perfect, tongues unhurriedly sliding against each other, savoring every second and every inch they could reach. Jungkook climbed over Jimin, straddling him for a short moment before Jimin turned them over again, staying on top.
Jungkook tangled his fingers in Jimin’s blonde locks, baring his neck when they broke the kiss, waiting for a mark that he knew wouldn’t come. It pained Jimin every time to have his boyfriend, his promised mate silently begging to be claimed, and be forced to focus extremely hard not to give into his instincts. So unfair. But he made up to Jungkook by sucking other bruises on his skin and gently nipping along his shoulder and collarbones. Jimin’s scent was everywhere in the bedroom, Jungkook felt enveloped in it, hoping the cedar and cinnamon would stick to every surface for several days. Jimin’s mouth traveled down to his chest, sucking one of his nipples and making Jungkook drip slick onto the towel, barely wrapped around him. The older traced the lines of Jungkook’s abs with the tip of his nose, the warm breath causing spasms to run through his body.
Jimin finally reached the towel, throwing it away easily, Jungkook’s hard cock, red and hot, now exposed, and he leaned down to suck the tip of it and dart his tongue on the slit. Jungkook was a mess already, leaking slick and precum, moaning and panting, fingers still holding tight to his boyfriend’s hair and tugging. Jimin slid his tongue down Jungkook’s length, past his perineum, lapping up the slick that gushed out.
“A-alpha, please.” Jimin’s head shot up—Jungkook rarely called him that, showing so much submission, but Jimin loved it. He smirked, smug, and licked Jungkook’s hole again, holding his cheeks apart with his thumbs. “Alpha! I w-want your knot, please.”
“You taste so sweet, Kookie. Like juice.” Jimin whispered, coming up to mouth at Jungkook’s jaw. “And you’re such a good boy, you’d make a great dad.”
Jungkook sniffed. “You really think so?”
“I do, baby.” Jimin captured Jungkook’s lips in a slow, calming kiss before he could pout again and start crying. “How I wish we could have a pup. We will someday, okay?”
Jungkook nodded and Jimin smiled at him, looking into his bright eyes. The younger dared to curl his lips in a shy smile, his bunny teeth peeking out. Jimin’s heart flipped.
“Now alpha’s gonna fuck you really good.” Jungkook’s smile widened as he spread his legs further apart to better accommodate Jimin between them, his hands lifting the hem of Jimin’s shirt.
The sight of Jimin’s toned body and the wet spot on his boxers, perfectly outlining the head of his cock, had Jungkook squirming and gushing more slick. He ran his fingers down Jimin’s torso, tracing the letters of his tattoo, caressing his sides until he reached the waistband of his underwear, pushing it down just enough for Jimin’s dick to get out. Jungkook’s mouth watered and he squeezed the base of it around the area where the knot was supposed to form. Jimin nearly choked.
“You want my knot, I got it.” Jimin teased.
“Yes, please.” Jungkook sounded so innocent, Jimin wondered if he had hit his head somewhere. Who was that omega?
“What do you want from me, being so well-behaved?” The older slid off his boxers, leaning closer to Jungkook.
“I’ve said it, want you to breed me, Jiminie hyung.” Jungkook’s large hands cupped Jimin’s cheeks, he looked at him like he hung the moon and the stars in the sky. Jimin shook his head, perplex, and lined his dick to Jungkook’s entrance, pushing in slowly. He buried every inch in the younger’s wet and tight heat, being held down by the strong grip of Jungkook’s arms around his shoulders.
“Ah Kookie, you feel so good around my cock. I love you so much.” The words slipped easily from Jimin’s lips as he rolled his hips and started fucking in drawn out thrusts, pulling all the way out and rocking back inside, tearing sharp breaths from Jungkook.
“I love you too”, the younger managed to say between pants, so overwhelmed with the feeling of being filled so good. His mouth found Jimin’s earlobe, nipping at it and sucking at the sensitive spot behind his ear, scenting him. Strong waves of cedar and cinnamon filled his mouth every time he licked over his scent gland, Jimin’s thrusts becoming harder and faster.
Jimin spread Jungkook’s legs almost until his knees touched the mattress, angling their hips for better access to the boy’s prostate, his moans instantly becoming louder. His dick was trapped between their bodies, the friction from Jimin’s belly pushing him towards the edge too quickly.
“My alpha, my alpha…” Jungkook repeated under his breath like a mantra as Jimin pounded into him mercilessly. They were usually like that when they fucked—too caught up in the sensations, too lost in each other to think coherently, only their broken moans and the filthy squelch of the thrusts surrounding them. Jungkook held Jimin tight to his chest, as if even the shortest distance between them was unbearable. Jimin made the most of it, littering Jungkook’s jaw, neck, shoulders with red and purple bruises, leaving no skin unmarked. Their makeup artists would hate him the next day, but he couldn’t care less. If he couldn’t mate Jungkook, at least everyone would know who that boy belonged to.
“Jimin hyung, I’m- I’m close.” Jungkook said in a mewl. Jimin took a proper look at his face: his mouth hung open and his brow was furrowed, his red highlights glued to the sides of his face.
“Then come for your alpha. Let me see how much you like my cock.” Jimin’s voice was merely a mumble, his own orgasm not far from building up.
Jungkook rocked his hips back to meet Jimin’s halfway, head spinning and heat boiling in his belly, where his dick rubbed. Not too long after that, his whole body stiffened and he came all over his and Jimin’s torsos, his warm cum mixing with the sweat and making them sticky and gross. At another time, Jungkook would’ve cared, but his mind was blank, all he could register was Jimin’s knot starting to swell, catching his clenched rim. He tried his best to relax, but the oversensitiveness was too much to handle, tears starting to well up in the corners of his eyes.
“So tight, baby, so good for me.” Jimin praised, his mouth glued to Jungkook’s ear. He growled low in his throat when the knot was finally in, Jungkook’s tears rolling free down his face and onto the pillow. The large knot pressed incessantly to his prostate, his dick chubbed up again in record speed. Jimin gave a few other thrusts before he was coming inside Jungkook, coating his walls. He spilled so much cum, just as he promised, his body going almost limp in Jungkook’s arms.
“Thank you, hyung.” Jungkook breathed, his eyes drifting shut and his grip around Jimin loosening. The older turned them to their sides, careful with the knot still fully inflated up Jungkook’s ass.
“You’re welcome, baby boy.”
The knot took some minutes to go down, and Jungkook fell asleep in the meantime. Jimin couldn’t even close his eyes, too wired to let go of the beautiful view he had, the love of his life sleeping so peacefully in his arms.
He got up when he was able to pull out, going over to the bathroom to dampen a washcloth and clean Jungkook, but the boy was already awake when he got back. His omega must have been feeling sensitive from the baby fever, any distance between him and his alpha made him uneasy, even though they hadn’t bonded officially. Jimin could get used to that so easily.
“I’m here, love, don’t worry”, he said with a kiss on Jungkook’s forehead.
He noticed some of the cum had oozed out when he left, running down his thigh and pooling on the sheets.
“Can you plug me up? I want to keep it for a while.” Jungkook’s voice was still soft from sleep, lids feeling heavy.
“Of course.” Jimin reached for a box in the back of a drawer on the bedside table, coming back with a silver plug adorned with a pretty purple heart-shaped jewel. He finished cleaning him up and laid behind him, tangling their legs.
Jimin’s breath became stable, calm and heavy against the younger’s nape, finally ready for sleep. Jungkook had a hand spread out across his belly, fingers feeling the lean muscle of his abs, as defined as ever. His eyes slipped out of focus while his mind drifted back to the daydream, their pup, their pup…
“Baby, nothing is going to happen. I’m so sorry.” Jimin’s voice was as smooth as his hand sliding on top of Jungkook’s on his belly, intertwining their fingers.
“I know, I just… one day it’ll happen.”
Jungkook could feel Jimin’s smile on his skin, a soft kiss pressed on the base of his shoulder.
“Definitely, Kookie.”
