The Train to Busan

Summary:

In a world where alphas or betas could claim or mate an omega anywhere at any time, Jimin has done his best to save himself for an alpha. He finally smells his intended mate and will do all that it takes to have the alpha mate him - even if it's on a train.

OR

Omega Park Jimin is claimed and mated on a train to Busan.

Notes:

Hello, peaches! Just some words before you begin reading:

*** PLEASE HEED THE TAGS ***

This story contains:
1 - a free use universe, but is not written in the way that most free use universes are done (such as multiple people/strangers having sex with someone, usually publicly)
2 - semi-public sex as this takes place on a train
3 - Jimin is a boy here and has a pussy/vagina
4 - blood is mentioned lightly due to a mating bite
5 - feminization involved in which Jimin wears a skirt (is that the right term? I think so)
6 - mpreg is a possibility in this universe and is implied here (especially with the breeding kink)

If any of these things/ideas make you uncomfortable, then please, just go back and find a fic you will enjoy.
Some details in the story that I did not mention:
Jeongguk is older than Jimin.

I honestly think this could have been done so much better but ... here we are. Hopefully, you can somewhat enjoy my terrible smut writing ~ (also, this turned out way softer than I intended...)

(See the end of the work for more notes.)

Work Text:

Jimin double checks his items: bag - check, phone - check, wallet - check, keys - check. He quickly goes through his phone screen and confirms his train ticket is still there and also confirms the time to make sure he will not be late. Jimin looks at himself through his full-body mirror one last time to fix his oversized sweater and mini skirt, making sure it covers his privates enough. He doesn’t like wearing underwear and enjoys just letting his cunnie breathe, but he always has to be wary in covering it up. Even though he wants to find his mate, he also wants to be sure that his cunnie is reserved for that one alpha only.

Alphas can take an omega and have sex with them wherever and they won’t get in trouble. After all, omegas are mainly just cocksleeves and cumdumps for them. Jimin has yet to be taken by an alpha in his 20 years of life, but he wants to be sure that it will be someone who mates him (and that he will be at least attracted to a little bit hopefully). He even uses a scent blocker in order to keep the alphas at bay and so far it has worked. 

 Quickly walking to his door, Jimin slips into his white sneakers and sprays himself with a scent blocker from head to toe. Satisfied and triple checking his items again, he steps out the door with his small suitcase and walks to the train station. 

After a train transfer and a few stops, Jimin exits into the central station. He is going to the seaside to visit his parents who he hasn’t seen since his training in the most elite school for omegas. His wonderful appa and eomma are paying his rent for his small, but cute studio in the city and for all of his necessities such as food. Omegas that are not mated are not allowed to work, so Jimin has no choice but to be reliant on them until he finds his alpha.

Jimin pulls out his phone and checks which train route he is supposed to go on.

Train to Busan at 12:45 … Train to Busan at 12:45…

He scans the current directory for the trains in order to find which track he has to go to and finds the one he is looking for. “Track 20! Let’s go!” He says to himself, excited to go on a small adventure by himself.

The omega walks past the track numbers and finds track 20, walking to the escalator to wait by the tracks. His train should be arriving in 10 minutes and Jimin is proud of himself for being early. He stops walking at a random spot and waits patiently for the train, casually eyeing the tracks in the distance to see if the train is near.

He breathes in deep, taking a lungful of the crisp, fall air. He loves this time of year, the fresh air giving him a serene sense of happiness. He soon hears the whistle of the train and grins, trying his best to not jump excitedly and look like an idiot in front of strangers. As the train passes by him, it sends along a strong wind full of scents, but one seems to call out to him in particular. The smell of dark chocolate and sea salt wakes up his inner omega and Jimin frantically scans the platform to see if he can pinpoint who is exuding the delicious scent.

However, the train stops and a multitude of people exit the train and the scent becomes muddled, growing fainter. The omega pouts and decides to give up on the pursuit, his inner wolf clearly not happy about the decision. Jimin just doesn’t know how they’re going to find the alpha with that precious scent on such a big train!

After people stop exiting, Jimin climbs up the small steps and finds an empty cabin. He opens the sliding door and gets comfortable in the small area, pulling out the book he’s been studying for school. He plugs in his headphones and quickly falls into a relaxing headspace. Jimin barely notices the train leaving the platform, already immersed in his reading.

A few minutes pass and Jimin smells the scent of smoking wood, the presence of an alpha making himself known. Jimin’s heart pounds and looks up, but then calms down when he notices it is the ticket collector.

“Ticket please.”

Jimin presents the ticket from his phone and the alpha scans it quickly and is about to leave when another person enters the vicinity. Jimin’s inner wolf perks up because it’s them - it’s their alpha. Jimin can’t get a good look at the person since the other alpha is in the way of his view, but he still tries to maneuver his head around to peek a look.

“Oh! Hello, sir. Has your ticket been scanned?”

“Ah, no, not yet. Here you go.” 

Jimin sucks in a breath, his body growing warmer once hearing the sounds of the person’s voice. So it’s an alpha male… Jimin deduces to himself.

“Wonderful. You’re all set.” The alpha steps aside so that the ticket collector can exit and Jimin is finally able to see his alpha face-to-face. 

The first thing he notices are his large, chocolate eyes. They appear to widen when noticing the omega and Jimin is unsure if that is a good or bad thing.

“Oh, I’m sorry! I thought this cabin was empty. I’ll try to find another one.” The strange alpha quickly blurts out and turns to leave, but Jimin jumps out of his seat and grabs the others wrist to hold him.

“No!”

His dream alpha turns his head, eyes wide in shock. “No?” He questions, eyes flitting back and forth between Jimin’s eyes and his tight grasp on his wrist.

“I mean… You can sit here. You’re more than welcome to sit here if the other cabins are full.” Jimin slowly releases his hold and nervously bites his lip. He prays to the Moon goddess to please convince the handsome alpha to stay in his cabin.

“Well… if you’re okay with it.” He hesitantly responds. Jimin grins and holds the sliding door open for the alpha to settle himself inside. Jimin sits down once more and his inner omega preens at the close proximity of their potential mate.

Jimin tries to not stare too much at the beautiful man before him, but his eyes keep on being attracted to the alpha. He is wearing a white button down with black slacks and the omega almost drools at how fitted the outfit is on him, especially around his arms and thighs. The alpha seems to pay him no mind as he types distractedly on his phone, Jimin inwardly pouting at the lack of attention.

So, the omega then decides that he is on a mission! His goal is to make the alpha notice him and hopefully mate him. He softly clears his throat, but the alpha’s eyes stay glued to his phone screen. He clears his throat again louder and finally garners the handsome alpha’s attention. He raises his eyebrows in question, but doesn’t say anything, waiting for the other to speak.

Once the alpha’s eyes land on him, Jimin grows nervous and his mind blanks. The silence elongates and the more it goes on, the more anxious Jimin gets. His eyes drop down to a wallet sitting beside the other man and decides to point it out.

“Um, is that your wallet, sir? I’m sure you wouldn’t want to lose it.”

The alpha looks down beside him and picks up the item, quickly placing it back inside his pants pocket. “It is, thank you for letting me know.” He gives a soft smile and Jimin practically melts in his seat. The omega just nods, no longer trusting himself with his plan and just decides to stay quiet, focusing back on his book.

A faint series of vibrations distracts the omega and realizes that someone is calling the alpha. He quietly excuses himself and steps outside the cabin, leaving Jimin momentarily alone. At that moment, the omega suddenly wonders if the alpha already has an omega, his inner wolf whimpering at the sad thought. Jimin decides once more to try to talk to the alpha and find out more information about him.

Once he enters back in, Jimin looks up and smiles, angling his body towards the other.

“Seems like you’re a very popular man. With your phone blowing up like that, it has to be work or your omega.” Jimin giggles, trying to keep his comment lighthearted so that it doesn’t offend the alpha in any way. He gages the alpha’s bodily response carefully who in turn just blushes and nervously scratches the back of his head.

“Uh, just work, actually.” He sits back down and twirls his phone in his hands. “I don’t even need to answer all these emails since I’m technically on vacation, but I keep getting worried that something bad is going to happen without me there.” The item vibrates once more and the alpha just sighs.

“Oh, vacation? Where are you going?” Jimin tilts his head  to his right and stares at the alpha with wide, curious eyes.

“Busan. I have a beach house that I rarely go to in the area.” The omega gasps causing the stranger to eye him quizzically. 

“I’m going there too! I’m visiting my appa and eomma. I haven’t seen them for awhile since I started school.”

“Oh, what school do you -” The alpha is suddenly interrupted by another phone call and he frowns at the screen. “I’m sorry, I have to get this.” He lets out a heavy sigh and steps out again. “What’s the verdict, Seojun?” Jimin notices that the alpha’s voice deepens and is more sharp compared to how he was speaking with him. The omega feels his body heat up at the tone with a small dribble of slick escaping his hole. He needs to mate with the alpha, and he needs to mate with him now. Jimin’s pheromones override the scent blocker, freely filling the air in the small area.

When the alpha enters back into the cabin, his pupils dilate and eyes glow red at the scent of the sweet smelling omega. “You’re an omega,” he gasps out, body tensing.

“I am, alpha. I’m unmated, you see, and your scent is just so irresistible. My omega and I would love for you to claim us. I promise I’ll be the perfect omega for you. I’ll be obedient, be the perfect knotwarmer and you can breed me all you want, fill me with pups.” The alpha lowly growls at the thought, unconsciously stepping closer to the enticing omega before him. Jimin raises himself on his knees on top of the seat, slowly raising his skirt to reveal his bare cunnie. “I’ll take such good care of your pups. Please, alpha. Make me yours.” Jimin’s inner wolf spoke to the alpha’s wolf, connecting and bonding with each other.

“What a perfect omega I have right in front of me. How can I resist?” His red eyes rake over Jimin’s body, his mouth salivating at the unmarked neck where it lays exposed from the fallen collar. He slowly walks over and sets one knee on the seat beside the omega’s knee, bending his other leg to be at the same eye level. He leans his head down towards the omega’s neck, rubbing his nose over Jimin’s scent gland, drinking in his cherry scent while he holds a firm grip on Jimin’s hips. The alpha glides his tongue over it, letting the sweet flavor drown his senses. His scent of dark chocolate and sea salt mixes in the air with Jimin’s cherry scent, the omega drowning in it. More slick escapes his hole, Jimin spreading his legs wider to further tempt the alpha.

The alpha deeply growls in his ear and switches the omega around, running his hands under Jimin’s sweater, smoothing his hands across the soft flesh. Heat curls in the pit of Jimin’s stomach, focusing on the alpha’s touches, wanting - no - needing more.

“Alpha, please! Want your knot, need your knot!” Jimin cries out, leaning his head against the wall, arching his back and grinding his ass against the hardening cock. The alpha’s hands tighten around his hips, but he makes no other response. He allows Jimin to continue his teasing tactics, enjoying the small amount of friction and the sight of the omega’s bubble butt rubbing against him. After a few agonizing moments, the alpha could no longer hold back, running his hands back up towards Jimin’s chest, pulling him against his body. The omega mewls at being so easily manhandled, the alpha’s strength turning him on even further. The alpha then immediately stuffs Jimin’s cunt with two fingers, thinking only of prepping the omega for his knot. His fingers easily slide in given the amount of slick the omega is producing and Jimin loudly moans at the intrusion. 

Jimin can’t help but think that the alpha’s fingers are perfect, just long enough to hit his sweet spot,  his pleasure continually increasing. He fucks his fingers in and out of Jimin’s pink folds, the omega’s juices splashing across his thighs and on the seat below him.

Oh, hngh, al-alpha, right there!” Jimin cries out, his pussy easily swallowing the thrusting fingers.

The alpha just grunts in his right ear, adding another finger. Jimin spreads his legs further to allow more room and take the alpha’s fingers deeper inside. The alpha nips at the side of his neck, leaving a scattered trail of small red marks against his smooth, fair skin.

“Gonna take my knot so well, aren’t you, my little omega?”

Jimin just nods, and mewls as he feels the alpha pinch and roll his nipple between the alpha’s index finger and thumb. More slick gushes out from the added stimulation, the omega whining high in his throat. His inner omega thrashes wildly inside him, insisting to receive the alpha’s knot and his mark. Jimin cannot ignore his inner wolf and starts to beg.

“Alpha, I’m ready! Please, give me your knot, need your knot.” 

At the request, the alpha pulls out his fingers from Jimin’s soaking cunt and Jimin places his hands against the wall of the cabin, panting out of his mouth. The sounds of a belt buckle and a zipper causes the omega to turn his head in curiosity, eyes widening at the sight.

His alpha has his cock out, thick and flushed red at the tip. Pre-cum is already dripping out of the small slit and Jimin can’t help but lick his lips at the sight. He more so feels than sees the alpha reach between his folds, collecting his juices and Jimin watches him spread it across his hardened length. With a mixture of anxiety and excitement, Jimin arches his back as much as possible, trying his best to present in the small space.

“Fill me alpha, fill me up with your knot and breed me with your pups.” Jimin wiggles his hips, both his words and actions taunting the alpha. Without warning, a tight grip meets the omega’s hips and the alpha drives his cock inside the soft walls, bottoming out all at once. Jimin yells out at the forceful intrusion, this being his first time taking cock inside. 

“Oh, fuck, what a perfect, tight pussy my omega has. Gonna be so good for your alpha, hm? Gonna take my knot whenever and wherever I want, right?” The alpha asks, thrusting slowly in order to drag out the delicious feeling of being enveloped by the tight walls. Jimin can only nod, whimpering out a pathetic yes as tears pool in the corners of his eyes. 

The alpha roughly squeezes his round mounds, massaging the soft flesh. The omega’s ass jiggles in each thrust, the alpha mesmerized at the sight. He just wants to mark the pretty omega all over, and his ass certainly looks like a sweet treat. Jimin moans underneath him as the alpha thrusts at a certain angle and he knows that he has reached the omega’s point of pleasure. He teases around the area, giving what Jimin wants, but also easily taking it away.

The alpha begins an animalistic pace, completely uncaring towards the pleasure of the omega at this point and instead seeking his own release. He can’t stop staring at how well the omega’s cunt swallows his cock, his member shined with so much slick. Jimin can’t stop himself from almost screaming from the blissful mixture of pleasure and pain, the alpha forcing two of his fingers inside his mouth to quiet him down. 

“Ah, the perfect breeding bitch just for me! So wet, so fucking tight, fuckfuckfuck!” 

The base of the alpha’s cock begins to inflate and Jimin realizes that his knot is starting to form. The alpha brings his limp body back to his chest and Jimin tilts his head in submission, preparing himself for what’s to come. Hot breath fans over his scent gland, a shiver running down his spine as he feels the tickle of the alpha’s fangs. Once the alpha’s knot has fully formed, spurts of cum painting the insides of his walls, the alpha finally sinks his teeth into the intended flesh.

Jimin releases a sob, doing his best to stay still and not thrash around despite the pain. The Blood slowly drips down his shoulder towards his chest and back. His alpha’s arm wrapped around his waist is the only thing holding him up, Jimin completely exempt of energy. The fangs retract and the bite is replaced with soothing licks to close the wound, the omega purring in content. Jimin suddenly feels an overwhelming slew of emotions, some he doesn’t fully recognize as his own, and begins crying. He just wants to be held close, wants to drown in his mate’s scent.

“Alpha, alpha, alpha!” The omega cries out, not knowing what else to say or how to express himself.

The alpha rubs his nose up and down Jimin’s neck, releasing calming pheromones.

“Shh, it’s okay, omega. I’ve got you, your alpha’s got you.”

The alpha decides to sit down and waits a few minutes while his knot deflates. Once it has gone down a little, he quickly pulls himself out so that his mate can face him instead. Jimin’s sobs intensify when he is no longer plugged up, drips of cum and slick having escaped and rolling down his thigh. His breathing quickens as all he can think of is possibly not getting pregnant and starts to scratch down the alpha’s arms.

“Hey, don’t worry, c’mere.” The alpha enters back inside the tight, warm heat once the omega is facing him, ensuring that his mate is filled once more. Jimin’s eyes are watery, tears on the brink of rolling down his cheeks. He wraps his arms around his alpha and lays his head in the crook of his partner’s neck.

Jimin tries to control his breathing, inhaling the intoxicating scent of his alpha. His legs straddle his partner, and he slowly leans back to look at his mate. As their eyes meet, a warm feeling grows in his chest and he realizes that the emotion he is now feeling is peace. He feels at peace. 

“Thank you for mating me, alpha.” The omega suddenly grows shy, his cheeks reddening. He tries to hide his face behind his hands, the alpha cooing at the sight of the sweater paws. Despite the adorable sight, the alpha reaches up and easily pulls apart his hands away from his face.

“Jeongguk.”

Jimin tilts his head in confusion, unsure what his alpha means.

“That’s my name. Jeon Jeongguk.” Jimin’s mouth creates a little ‘o’ at the realization, repeating his alpha’s name and giggles.

“Nice to meet you, Jeongguk-ssi. I’m Jimin, Park Jimin.”

They begin to talk, trying to get to know one another. When nearing their stop, Jeongguk had insisted to clean up Jimin, who began to cry at the thought of no longer being knotted or having his alpha’s cum stay inside him. Jeongguk promises to fill him up again later and that slightly appeases the omega. 
Jeongguk pulls out and places Jimin on the seat, kneeling down on the floor.

“Spread your legs for me, baby.” He instructs, Jimin immediately obeying with a shy look. 

The omega’s face reddens as his alpha just continues to stare at his cunnie like a treat. He whines, embarrassment flooding his system, but he does not dare to close his legs even one centimeter. The whine seems to pull Jeongguk out of his thoughts and he leans in, placing his mouth directly on the wet lips. The alpha knows this is only meant to help clean his mate, and not to provide pleasure. So, he decides to quickly dart his tongue in and out of the entrance, but can’t help and moan at the taste of their coupling. Their scents perfectly mix together and it gives alpha an odd sense of pride. 

Jimin intakes a sharp breath, eyes rolling back at the feeling of his mate’s tongue fucking in and out of his pussy. Jeongguk sucks at his entrance, swallowing down the new production of slick. He leaves one last lick between his folds and leans back, slightly panting. He licks the corners of his lips to clean up any remaining slick, addicted to his omega’s cherry taste. Jimin is completely dazed out, eyes hazy and unfocused, the alpha purring in content at seeing his mate pleased.

“Come on, baby. We gotta go. Do you have any underwear with you?”

Jimin blinks slowly, trying to come back down from his temporary high. He then shakes his head in the negative, placing his legs back down as Jeongguk stands.

“Okay. I’ll get all of our things, so fix yourself up, baby.” Jeongguk leans down, placing a soft kiss on Jimin’s lips. It leaves a small smile on the omega who is so content and he begins to fix his outfit as much as possible. The small traces of blood cannot be helped until he washes it off in a bathroom, so he tries to have his sweater avoid the bitten area as much as possible. 

The train announces their stop, coming to a slow halt. Jeongguk opens the sliding door, letting Jimin exit first and following closely behind. He doesn’t have to carry much, just his duffle bag and Jimin’s small suitcase and the omega insisted on carrying his own purse. They hold hands as they walk through the train station, easily following the signs to their exit.

Jimin feels his phone vibrate, pulling it out from his bag and gasping at the text he received. He just remembered that his parents promised to pick him up and they are both waiting at the exit for him. He suddenly feels nervous, but turns to his alpha nonetheless who eyes him curiously.

“Something wrong, baby?” The pet name continues to naturally roll off the alpha’s tongue and Jimin loves it.

“Uhm, no. I just… well, I forgot that my parents are here to pick me up. But I don’t really know what to do. My omega and I want to stay close with you, especially since we just mated. But I promised my parents I would spend time with them, especially since I haven’t seen them in forever. I know this may be all too sudden, but would you like to meet them? Maybe come over to have something to eat?” Jimin gives his best pouty face and puppy eyes, and who is Jeongguk to deny that?

“It’s not a problem at all.” He softly kisses the top of the omega’s forehead, Jimin bursting with happiness. “Let’s go and meet your parents, we shouldn’t have them wait too long.” 

They casually continue walking towards the exit and once they are back outside, they see an older couple holding a sign that says “Welcome home, Jimin!”. The omega laughs and runs to hug his parents. He tightly embraces his appa, leaving a quick peck on his cheek. He then turns to his eomma and hugs her tight, as well. Small drops of tears roll down from the corner of his eyes as he smells the comforting scents of his parents. 

“Oh, my baby! Eomma has missed you so much.” His mother steps back from their embrace, but still holding onto his hands,  some tears of her own having escaped her eyes. 

“I’ve missed you too, eomma.” Jimin lets go of her hands and takes a deep breath. “Actually, I wanted you both to meet someone.” The omega turns around and urges the alpha to step closer. “Appa, eomma, this is Jeon Jeongguk. My alpha.”

Jimin does his best to not laugh at the shocked look on his parents faces, eyes wide and mouths slightly open.

“Hello, I’m Jeon Jungkook and it is very nice to meet you.” He gives a deep bow in sign of respect, then stands tall, wrapping his right arm around Jimin’s waist.

“Oh, darling, you found such a handsome alpha!” Jimin’s eomma squeals out, then opens her arms wide. “Welcome to the family, Jeongguk!” She hugs him tight and then cups his face in her hands. “You treat my baby well, you hear me?” Despite the teasing tone, Jeongguk could very clearly see the threat in her eyes and gulps.

“Yes, ma’am.” She just pats his cheek and gives him space to breathe again.

“Well! How about we all head home and have something to eat together, hm? And we’ll need to clean up your bite, sweetie.” She points to the wound and Jimin nods his head. “Alright, let’s go!”

Jimin and Jeongguk follow behind Jimin’s parents, smiling at one another.

“I’m so glad I took this train to Busan.” Jimin softly whispers to his mate as they sit in the backseat of the car.

“Me too, baby.” Jeongguk quickly kisses Jimin’s soft lips, a small smile adorning his face.

Ironically enough, Jimin’s appa also mated with his eomma on a train to Busan, so Jimin views it to be fate.
