Kookie let out a nervous, yet excited breath as the lift ascended all the way up to Yoongi's penthouse, curious about the alphas' plans for the night. He had finally turned sixteen yesterday, and had celebrated with his family, but the hyungs had wanted to throw him a special birthday party with only the four of them there with him. Everyone said that the sixteenth birthday was a big deal for an omega, and that all omegas were sent to specialized schools after that, so Kookie was really curious about what kind of birthday party they had in mind.
He didn't get to ponder more on it though before the doors were opening right into Yoongi hyung's place, the four alphas waiting for him. There were loud, excited yells when they spotted him, his ears attacked with excited cheers of "Happy Birthday!"
Kookie giggled, shyly fidgeting with the hem of his tee. "Thank you, alphas."
"Come, come," Seokjin welcomed, placing a warm hand on his backside and urging him to come closer to the four alphas. "It's a day late, but you're our special little omega today, aren't you?"
"He's always our special little omega," Hoseok interjected with a laugh, making Kookie blush at his words. He'd never get used to the affection these cool, older alphas showed a kid like him.
"We thought we'd give you your gifts first," Namjoon spoke up, twinkles in the eyes that Kookie loved so much. "And then we're going to go out to celebrate."
"Ah, you didn't have to, alphas," Kookie demurred, bowing his head. "Spending time with you is gift enough."
"Really?" Namjoon pouted, amusement clear in his expression. "Yet you still haven't given alphas any kisses yet. We'd start thinking you don't like us."
Kookie gasped, horrified at his oversight. He had been so curious about the party, that he'd completely forgotten to greet the alphas like they do to him. "I didn't mean to! I swea–mmmph!"
His words were cut off by an impatient Namjoon, who had grabbed him by the waist and pressed his lips against him in a searing kiss. Kookie's mind went blank when the alpha probed at his lips with a wet tongue, the omega obediently opening his mouth and giving him access like always. He was dimly aware of being passed around and being kissed and groped by the four alphas, but even after all the kisses they have shared every time, it still left him dazed and stupid.
When they finally let him go, Kookie was panting with saliva drooling down to his chin, wrecked so soon into the night. The alphas smiled smugly, gently leading him to where a pile of gifts were waiting.
"Open them, sweetheart," Seokjin ordered, gesturing to the gifts.
Kookie stared in awe at the sheer number of boxes, overwhelmed. "You didn't have to."
"But we did," Yoongi answered with a casual shrug. "This much is nothing, we like taking care of what's ours."
"And there are some special gifts at the end," Hoseok added with a wink. "Open these first so that we can get to them, yeah?"
Kookie nodded and plopped himself down on the plush carpet next to the pile, obeying what the alphas told him. All the gifts were lovely, from dainty jewellery to pretty plushies– everything an omega could want. He made sure to thank them after every gift, drawing fond smiles from the alphas, who were watching from above on the sofas surrounding Kookie. They occasionally dipped their head for more kisses, which the excited omega bestowed gratefully.
Once he was done, the alphas got up. Kookie looked up at them with wide, curious eyes, until Namjoon bent down and picked up the lithe omega with both hands gripping his waist. Kookie went red at how strong and large the alpha was compared to his tiny omega body, the ease at which he was picked up making his pussy throb. Namjoon deposited him on the couch, declaring that it was now time for the special gifts.
"You're now of age, darling," Seokjin explained kindly, patting Kookie's head. "Alphas want to give you something that will give you a headstart in your new studies."
Kookie went wide eyed. "Really?" He breathed out. He had been super nervous about what kind of things they'd teach him, so this would be a big help. "Thank you alphas! Koo was worried– I've never been good at school, so I was super scared."
Yoongi snorted, and the other alphas seemed to be stifling laughter at his words.
"Eh, don't worry brat," the short alpha said. "You'd be a natural, trust me."
"Enough talking!" Hoseok interrupted, before Kookie could ask what that meant. "We're beginning with my gift first!"
Namjoon rolled his eyes. "Fine, fine, it's not like we already agreed on that or anything."
"Exactly," Hoseok beamed, picking up a box from the side table and passing it to Kookie. The omega held it gratefully, carefully pulling at the ribbon to open the package and reveal a gorgeous dress inside.
"For me?" He breathed out, running a hand over the lacy details.
Hoseok smiled at his reaction, motioning for him to wear it. "Now that you're sixteen, you can wear whatever you want, baby. So what's a better gift to commemorate that than a new dress? Put it on, sweetie."
Kookie nodded, shyly stripping off his tiny cropped tshirt and shorts, going pink at the way the four alphas were following his every move, gaze dark and hungry. He didn't know why they were looking at him like that, but when his hesitated near his panties, Namjoon let out a growl, making Kookie shiver.
"Off, omega." He commanded, and Kookie scrambled to obey. He peeled off his wet panties, revealing his glistening pussy coated with slick.
Seokjin cooed at him, reaching out to run a hand over his folds, making Kookie squirm. "Aww, did the little baby get this wet just from a few kisses?"
Kookie flushed in embarrassment at being caught. At least they didn't know that Kookie starts dripping nowadays even when they hug him, their hot, musky alpha scents doing things to his head. "Alpha…"
Seokjin gave his mound a reassuring squeeze. "It's fine if you do, sweetheart. Nothing to feel bad about."
"I– I'll wear this now," Kookie replied instead, changing the topic. He blindly grabbed whatever he could reach first from the box, picking up a gorgeous black and red corset. He held it with one hand while searching for the top to go underneath it, but Hoseok plucked the corset from his grip.
"Let me put it on your," he purred, reaching around the omega and buttoning up the back of the corset. "Baby just needs to sit there and look pretty."
Kookie pinked and let the alpha dress him up, watching curiously as Hoseok tied a lace collar around his neck and a tiny, frilly skirt around his waist. Next came a pair of lacy, thigh high black stockings, with large, chunky heels to complete the look.
"Do you like it?" Hoseok asked, and Kookie touched himself here and there to figure out the outfit. He couldn't see how he looked because there wasn't a mirror in the living room, but he could tell that his breasts and pussy were fully exposed. There seemed to be no shirt to go under the corset around his stomach, so his tiny breasts were completely open, nipples perked up from the cold. And the skirt was frillier at the sides but really short at the front, so much so that the border of the last frill barely rested midway over his cunt. Kookie had a feeling that if he walked in it, every movement will flash his pussy to everyone.
"Is-is this really okay?" He stuttered, pulling at his nipples.
Yoongi seemed to have misunderstood the question, because he answered, "It's fine. No need to worry about your chest, kid. You just turned sixteen, that's when omega's bodies undergo dramatic and rapid changes. You'd grow into the outfit."
Kookie flushed, imagining the sight that Yoongi described. "I– that's not it, alpha. I mean, um, should I put my panties back on? I didn't wear any bra when leaving my house though…I'm sorry."
"Silly omega," Hoseok scolded, giving his pussy an affectionate slap. "You're a grown omega from now on. You can now go out naked on the streets if you want to."
Kookie flushed even more at that image, unaware that the alphas didn't just mean it as a hypothetical scenario. Alphas could legally do whatever they wanted once an omega was of age, and they definitely planned to show the omega off on the street at some point, even if the omega refused. But then again, with how well they have slowly brainwashed him into being a needy cockslut, they knew he'd be a natural once he learns more about the duties expected of an omega.
"You guys take so long at this," Namjoon complained, drawing everyone's attention. "Time for my gift."
The alpha fished out a box from the same side table, handing it to the dolled up omega. Kookie opened it, revealing something he couldn't identify. They seemed to be similar to clothespins, except made of sleek metal, with silver chains hanging from one pin to the other. He looked up in confusion at the alpha who had given it to him. "Um?"
"You use it like this," the alpha said, picking them up. He brought up one of the clothespins to Kookie's chest, clamping down on his nipple without warning. The omega let out a pained moan, shuddering when the alpha did the same with the other nipple. He then let go, the chain hanging in between Kookie's chest. The omega squirmed at the heavy, tugging sensations assaulting his sensitive nubs, the chain having a lot more weight than he expected. It swung with every movement he made too, continuously pulling at his nipples and sending jolts down to his pussy, slick gushing out of it.
"Perfect," Namjoon hummed, scooping up a bit of slick with his finger and giving it a lick. He looked over to his brother. "Jin hyung, you wanna go next?"
"Obviously," Seokjin scoffed, but his smile turned kind as brought out his box. This time, instead of handing it to Kookie, the alpha opened it himself, explaining as he did. "I know my little baby won't know what to do with this, so let alpha teach you."
Kookie looked in some confusion as Seokjin brought out a large, vaguely cylindrical plastic object out of the box, feeling a sense of apprehension run down his spine for reasons he didn't understand. Seokjin had been right though, the naive omega had no idea what it was or what to use it for. All he could tell was that it was really big and long, being shiny black in color with bumps and ridges running all around it.
"Now, this is a really special toy made for older omegas, because you're not a kid anymore." the alpha explained. "Open your legs wide so that alpha can show you how to play with it."
Kookie gulped, hesitantly spreading his legs. It was embarrassing to show them how wet his cunt already was, but the alphas seemed to like it, because their scents became even stronger. There were even odd tents in their pants near the crotch, but Kookie had no idea what it was. He figured it might be some alpha thing, what would a stupid omega like him know?
Seokjin lined up the tip of the toy with the omega's pussy, briefly glancing at him in a silent order that he was starting. Kookie squealed loudly the moment the tip spread his pussy lips apart, the girthy toy being pushed inside at a slow yet steady pace. Loud moans kept falling out of his pretty pink lips at the penetration, the omega involuntarily arching his back. His restless motions made the clamps pull even more on his nipples, making the omega squirt out slick with obscene squelching sounds. Tears gathered in his doe eyes at the feelings of his pussy being stretched more than he thought possible as the toy made its way almost halfway buried in his warm cunt. Through his hazy gaze, he could see some of the alphas let out stifled groans and start palming themselves over their pants, but he was too distracted to dwell on it.
By the time Seokjin had fully inserted the dildo in the omega all the way to its base, Kookie was lying limp against the plush cushions, letting out soft, involuntary moans. Every tiny movement made some part of his pussy walls brush against the ridges of the toy, and it was absolute torture when combined with the nipple clamps.
"What do you say to alpha, honey?" Seokjin prompted sweetly as he stood up, absently licking slick off his fingers.
"Th-thank you," Kookie slurred, eyes following Seokjin's tongue.
"Good boy." Seokjin bestowed him with a smile, and it made the whole thing worth it. If alpha praised him like that, Kookie would take in as many toys as he was given. And he wouldn't admit it, but a shameful part of him had even enjoyed it. Too much.
"Okay, my turn," Yoongi announced. Kookie's breath hitched in anticipation of what the alpha would produce, and when the man opened his box to show the omega, it was yet another confusing object. It reminded him a little of Seokjin hyung's gift, yet unlike that, this was shorted and metallic, with a jewelled bunny shape at the base.
"Do you know what it's for, omega?" Yoongi asked, sounding like he already knew the answer.
Kookie bit his lip and shook his head, feeling terrible for appearing like an ignorant, stupid kid in front of these older, cooler alphas. But Yoongi just smirked, patting his head and then pulling on the chain, making Kookie let out a scream.
"Don't worry, alpha will teach you," Yoongi crooned. "I need you to turn around for this. Get on your knees."
Kookie was confused, but he tried to do as he was told. The sofa was really big, so with some careful maneuvering, he'd have no problem getting into the position the alpha had ordered. It were the toys that were the issue, the sensations almost making him black out. He moved agonizingly slowly, but he still couldn't help the wanton moans and tears that slipped out continuously from his cute, rosebud lips.
"Ass up," Yoongi commanded once the omega was on his knees, and Kookie scrambled to obey, unaware of the effect he was having on the alphas. The position he was in was almost that of an omega presenting itself to be taken, and the alphas were barely controlling themselves from taking out their cocks and fucking him into a mindless bitch.
Yoongi let out a sharp growl in a reminder for himself and the others to be patient, focusing on the buttplug instead. He laid a pale finger on the omega's clenching asshole, enjoying the way the omega shivered at even this much.
"Your gift is going to go here, okay, baby?" He instructed. "Hyung is going to put it in for you today, but I fully expect you to learn how to do it yourselves soon."
With that, Yoongi pushed the buttplug in the same as Seokjin had done with the dildo, drawing equally broken reactions from the now very, very overstimulated omega. The naive baby could only keep moaning and crying, not even fully aware of what was going on. His moan got louder the second Yoongi switched on the vibrator setting of the plug once it was completely it, a large shudder moving through the omega's entire body. The already thick scent of arousal became even more intense with the smell of strawberries, an obvious indicator that the omega had just orgasmed. Yoongi chuckled, remembering the first orgasm they had drawn out of a fourteen year old Kookie. The omega had been so cute and panicky at the foreign sensations, convinced that he just peed himself. It was a shame that Seokjin had plugged up his cunt, it was always a lovely sight to see cum streaming out of that pussy, mixing with the thick slick.
Seokjin reached out to position Kookie back in a sitting postion. They let the omega calm down a little and come back to himself, and if Namjoon and Hoseok had pulled out their cocks from their slacks to rub one out, then neither Yoongi nor Seokjin had the heart to scold them. It wasn't like the omega was in any sense of mind to notice– and even if he did, it was fine now. He'd know about pleasing alphas sooner than later anyways.
"'yungs?" Kookie murmured after some time, blinking rapidly.
Hoseok was immediately at his side, all smiles. "We're here, baby."
Kookie nodded, blushing. It seemed that now that he was more aware of his surroundings again, the embarrassment was hitting him. Ahh, their baby omega was so cute.
He dipped his head in a bow. "T-thank you for the gift-hnh– alphas. Kookie a-appreciates it", the omega said softly, speech stuttering because of the jolts from the vibrating buttplug.
"You're welcome," Namjoon replied. "Now let's go, shall we? Or else we'd be late for our dinner reservations."
The omega paled, fluttery hands brushing against his skirt hem. "L-like this?" He asked, mortified at the thought of appearing like this in public and the fear of whether he'd even be able to walk.
"Of course. We know our darling can handle it," Seokjin consoled, motioning for him to stand up. "You're a big boy now."
Despite the words, the omega still looked unsure, and for good reason. Even standing up was nothing short of torture, and his knees immediately gave out. But falling down on the floor rustled his nipple chain hard, making black spots appear in his vision. None of the alphas moved to help though, and Kookie clenched his teeth, determined to be the grown up omega they trusted him to be. He didn't know how long it took him to finally push himself upright, or how he managed to stumble towards the car, his breasts and holes getting assaulted with every step.
It was worse on the car– Kookie had always thought the alphas' fancy, expensive cars ran super smoothly, but today he could feel every vibration thrumming through the vehicle, reaching up his already sensitive ass.
By the time they got to the restaurant, he was beyond paying attention as the alphas half dragged him by the arms into the place, or of the lustful gazes and hushed whispers his appearance elicited. The alphas had booked a table in the centre of the expensive establishment, making sure everyone could see their beautiful omega. They cooed and doted on their mindless baby the entire meal, occasionally playing with the toys in between feeding him bites of the food. The teardrops that collected in his eyes when they tugged on his clamps were adorable, and so were the moans when they twisted and thrusted the dildo.
The omega was dumb and dazed throughout the meal from all the overstimulation of the evening, but the alphas knew he was a little cockslut through and through, because despite everything, he was still cognizant enough to thank the alphas for their time through garbled, slurred words once they were in the car.
"You're welcome honey," Seokjin purred.
"Hey," Hoseok interrupted, a wicked gleam in his eyes. "How about a commemorative photo to mark the occasion? A sixteenth birthday comes only once, you know."
Kookie agreed softly as expected, because when has he ever refused his cool, older friends anything? It was already surprising that they spent so much time with him, he couldn't believe they'd even want to take a photo of him.
"Is-ish it okay if I post it on my Instagram?"
"Oh, it's more than okay," Yoongi grinned darkly. "I think everyone should know about our special relationship ."
Later, the alphas' phones with ping with a notification about a new post that was uploaded on Kookie's account, the innocent omega managing to type an amazingly obscene caption without being aware of it. The post had already racked up a crazy number of comments from his classmates within ten minutes of it being up, and they smirked to themselves, marvelling at their perfect omega that would soon belong to them, and them only. For now, they could let the alphas of his school use him for a little fun.
[Picture of the omega leaning on a car seat, almost folded in half with his frilly skirt bunched around him. His legs were wide open and reaching near his shoulders. The position showed both his pussy and his asshole, the base of the dildo and buttplug clearly visible. Above, the chain dangled from the clamps on his erect nipples. The omega was making peace signs with his hands, tongue lolling out and eyes rolled up.]
'Thank you to the alphas for the best birthday ever!! I'm soooo grateful for all your gifts! Kookie is sorry that I'm too stupid for them, but I promise to practice more so that I can make alphas proud 💕 if anyone wants to help me learn, please lmk 💖'
