Chapter Text
It is nearly impossible for Namjoon not to notice when Jimin's small A-cup breasts begin to swell. Of course, they all notice because they are all looking, all of the time.
Jimin is small for his age, a contradiction in appearance of purity and sin. He has a round ass and beautifully plump lips and a face that is at once sensuous and innocent. But what Namjoon loves most about the hybrid is his perky little tits.
As small and almost unnoticeable as Jimin's breasts are, all his male, human friends are hyper aware of their presence. And Jimin, innocent Jimin with his long pretty cow eyelashes and twitchy calf ears sticking out the side of his head, has no idea how much of a distraction his chest is to his friends.
He is simply glad that a group of human friends have so easily accepted an animal hybrid into their midst. They treat him kindly, make him feel like an equal, sing stupid songs with him at noraebangs, spend hours with him at PC cafes, and he never feels like an outsider.
Namjoon doesn't think he's the first to notice that Jimin doesn't wear a bra. His little titties jiggle with the slightest movements and Namjoon can't stop himself from sneaking glances.
Namjoon catches others out in the act as well and they share guilty looks. After only a few weeks, he knows for certain he can't be the only one who shoots his fapple sauce every night to despicable fantasies of their hybrid friend.
Soon their perversions and lusts begin to overlap in a beautiful, twisted way. It leads to drunken confessions in Jimin's absence and eventually, some morally dubious scheming and pacts between the human friends.
And Jimin, poor oblivious Jimin with his budding breasts and cute swishy little tail, hardly notices. In fact, when Jimin's tits begin to grow, his friends are certain that they notice before the hybrid himself notices.
Jimin is more than happy to move in with them when they offer. He has a whole room to himself and he can inflict his affection on his friends whenever he wants. It's perfect for him.
And it's perfect for them.
They like to keep the room temperature low. That was actually the first time they noticed how hard it was to ignore Jimin's lack of undergarment. His udders are so pretty, so soft and peaked in the cutest nipples that pebble in the cold - it's nearly impossible not to stare.
After that day, they are all somehow on the same page about the AC without discussing it. And the house generally remains a cool low temperature.
They get to feel his small breasts pressed against their backs when he hugs them from behind. They brush against his tits accidentally, with the back of their hands while passing something to each other, or simply while talking and gesturing. They've gotten good at it. And Jimin always rewards them with pretty blushes and incoherent stammering and bad attempts at pretending he didn't notice anything.
The time is coming when he will need to be milked, and they all know it. The milk he produces will make his small titties expand and protrude, heavy and swollen, waiting to be released and dripping out when it becomes too much. He's going to be a proper cow-hybrid, with full aching breasts.
They all fantasize about it in different ways and Namjoon, after imagining every possible scenario of Jimin in various helpless needy predicaments, is running out of creativity for imaginary fap material.
The first time Namjoon researches cow hybrid lactation, he tells himself he merely wants to be prepared to help his friend out, should the need arise. Nothing wrong with being prepared.
His search leads him to educational videos on proper milking techniques and he learns a lot about the right way to pull milk from a hybrid's tits, the right way to touch them.
And he nearly strips his dick in the process of learning.
Most of the videos seem to be very clinical. But then he stumbles upon nursing videos where men pull milk from the nipples of hybrids with their mouths, sucking and drinking and moaning at the taste while the hybrid becomes visibly aroused from the feeling and tries not to touch themselves, just moaning cutely as their little tails swish about.
It is a dreadful spiral after that, to a porn category he has never ventured near before and Namjoon watches everything in it. For purely scientific reasons of course.
He finds videos of cow hybrids sucking on each others udders, boys with their little tits hooked up to suction machines while a different machine pushes large dildos into their tiny holes, calf boys taking huge cocks while their small cow breasts are suckled.
And Namjoon thinks he’s never seen anything more beautiful than a pretty calf boy crying because his udders are too full and crying even harder when he is milked and finally finds release from the pressure. If his favorite calf boy resembles Jimin a bit too strongly, it’s probably a coincidence. If Namjoon sometimes returns to watch his favourites, that is nobody’s business but his own.
For this reason, he doesn’t blame himself when Jimin comes to the breakfast table and the first thing Namjoon does is check how much the little calf's tits have grown overnight. They jiggle cutely when he sits and he's wearing a white t-shirt today so that the dark areolas are visible if you look hard enough. (Namjoon tries not to look hard enough).
They aren't large by human female standards but they seem to be troubling the hybrid boy this morning. He touches his udders absent-mindedly, probably thinking that no one will notice. Maybe they hurt, Namjoon thinks. And he wonders if Jimin is going to have to milk himself.
He has to really strain his self control in order to drag his eyes away and back to his bowl of breakfast but the sight of his sugary cereal floating around in a pool of sweet white milk only puts his mind back on the calf-boy's lactation.
No one asks Jimin if he's okay and Namjoon realizes that everyone else, like himself, is pretending not to have noticed.
Whenever he thinks no one is looking, Jimin gently massages his chest. He presses it softly and tries to alleviate the growing discomfort. He sometimes lets out soft frustrated sighs, like he does when he's asleep and it gives Namjoon the biggest guiltiest boner he's ever had.
__________
Even though Namjoon has little to no faith in a deity, he says a small prayer of gratitude for his good fortune when he is the one whose fortune allows him to stumble upon a sobbing Jimin. He doesn't need to ask what's wrong but he does anyway.
And Jimin sniffles. His long ears, unmistakably those of a calf, twitch cutely and Namjoon resists the urge to coo.
"What's the matter Jimin?"
The boy is sitting on the floor, back against the tiled bathroom wall and arms wrapped around his knees like someone who had been banished to the bathroom as punishment. “It hurts hyung. It hurts so bad and I don't know what to do,” he sobs, red-rimmed eyes looking up at Namjoon from under long eyelashes.
Oh god, why does he look so cute when he cries? Just as pretty and needy as Namjoon imagines in his dirtiest fantasies. Eyes wide and sparkly with tears as he sits defeated on the bathroom floor.
“What hurts Jiminie?” Namjoon asks gently, crouching so that he can be at Jimin’s eye level.
The hybrid blushes so bright and so red, Namjoon is surprised his face doesn't catch alight.
His demeanor changes quickly and he sits a bit straighter. “It's- I'm alright hyung," he says, wiping his face and offering a shaky smile. "Don't worry about it, okay? It's not a big deal."
"Don't lie to me kid. I know something is wrong. I’ve never seen you cry like this." Namjoon moves from crouching to properly sitting on the bathroom floor opposite Jimin.
“Are you sick? Should I get a doctor or an ambulance?”
“No, it's uh, it's not that."
“Then let me help you Jimin. Tell hyung what’s wrong.”
“I don't think it's something you can help with.”
“Bit presumptuous, don’t you think? Why don't you tell me and then we'll know for sure.”
“No. You're gonna laugh,” Jimin presses his face into his knees so his words were muffled. "It's a hybrid thing.”
Namjoon gives one of the calf's ears a sharp flick like a scolding and Jimin looks up again, surprised and disgruntled.
"Have I ever laughed at a hybrid thing before Jiminie?" Namjoon asks, sounding slightly offended.
Jimin's manages to look sheepish. "N-no I guess not." He looks at Namjoon, holding his gaze and Namjoon doesn't say anything. Merely waits. Jimin eventually speaks, soft like a kid on his first day at kindergarten. "It's- it's my chest. It hurts."
Namjoon makes sure to keep his face neutral as he surveys Jimin's posture. Curled in a way to intentionally hide his chest. When Namjoon finally speaks, its carefully paced, thoughtful.
"Can I tell you what I think Jimin?"
Jimin nods, lower lip pouty.
"I think you’re reaching your age of maturity."
"I’m already of age though," Jimin frowns in confusion.
"No…" Namjoon doesn't mean it to sound so patronizing. "I mean for cow-hybrids. You're only a baby cow, Jimin. I think you're just growing up. It's normal."
Jimin looks away awkwardly. "I- I wouldn't know." He straightens his legs and Namjoon has a hard time ignoring Jimin's swollen udders.
"Don't you have, I don't know, traditions? Isn't someone supposed to help you with… that?" He tries not to gesture too directly at Jimin's chest nor stare too much.
"I don't know hyung." Jimin sighs. "My parents aren't around. They never taught me these things."
"Don't you know any other cow hybrids Jimin? Haven't you played with other calves before? Touched their breasts or helped them when they were leaking?"
"N-no. I don't know any." Jimin sounds ashamed.
"That's okay Chim." He places a reassuring hand on Jimin's knee. "We'll help you, alright? I have some knowledge about cow hybrids."
"You do?" Jimin's eyes widen adorably. They're no longer as red from tears as they were when Namjoon walked in.
"Yeah I know all about milking and Yoongi-hyung knows a lot about the traditions."
Jungkook knows a lot about how to sell hybrid milk and make a lucrative business out of it but Namjoon decides to leave that part out.
Jimin's eyes are wide with hope now, looking at Namjoon like he's a free tutor for a course he's failing."You think they'd help me?"
"Of course they will Jimin. We all will." Namjoon gives him a reassuring smile, an expression that exudes confidence in their ability to take care of Jimin but the hybrid boy seems to be losing that small flame of hope.
His shoulders sag and he looks down at his fingers. "But what do I do until then?"
"What do you mean?"
Jimin is earnest now, far less shy. "I tried to milk myself but I don't think I'm doing it right. It still hurts and nothing really came out."
Namjoon notices that it's a little easier for Jimin to say the word milk now. He doesn't stutter over it.
Namjoon remembers reading about this. About how young cow hybrids often had difficulty expressing milk at first and he remembers the image that had popped into his mind of Jimin squeezing at his chest while crying and trying to get the milk out.
"I can help you if you'd like?"
"You'd do that hyung? Isn't that… weird?
"Not at all. You're a cow hybrid. What else are you supposed to do? If you need help, you need help Jimin."
Jimin blinks at him, clearly trying to understand whether that was rhetorical or not. He has no idea how cow hybrids usually go about this. It's not like it has ever happened to him before.
"Can you take your shirt off for hyung?"
"I- uh… now?" Jimin’s jaw tenses and his hands twitch awkwardly in his lap.
"If you still want me to help you, then yeah," Namjoon says, getting to his feet.
Jimin doesn't stand up with him.
"Oh my god." He suddenly covers his face with his hands. "I can't do this. It's so embarrassing I can't even look at you hyung."
"There's no reason for embarrassment Jimin but if you don't want to do this, we don't have-"
"No! I want to! Please help hyung! It hurts a lot. It's like… heavy. And- and-" he curls in on himself, shielding his body from Namjoon's gaze again.
"Full?"
"Yeah."
"Alright how about this?" Namjoon holds out a hand for Jimin to take and then pulls the reluctant boy to his feet. "Turn around. That way you won't have to look at me and I won't see your face alright?"
"I- uh- okay."
It takes Jimin a few breaths to compose himself before he grabs the hem of his shirt and pulls it over his head. He doesn't turn around.
"Aww, you wear a bra Jimin?"
"Shut up." He doesn't sound angry. He doesn't sound embarrassed. He sounds something else.
"No it's cute. But you're going to have to remove it."
It is obvious that it needs to come off but each step is like an arduous hike up a mountain for Jimin. It takes mental preparation and strength of will before he can reach back to unclasp it. He is nervous. His fingers are shaking, his arms bend backward at an unnatural angle and he can't get a grip on the hooks. "I- uh-"
"Can I help you there, little calf?"
He lets his hands fall to his sides in defeat.
"Yes please. It's um… new. I'm not used to all this-"
"You don't have to be embarrassed Jimin. It's normal for a little calf when their tits start to grow." He snaps the bra open easily but lets Jimin pull it off the rest of the way. It is a simple bra, no fuss, no decoration or design, just plain black. Functional. "It means you're becoming a big cow."
Namjoon steps forward until his broad muscled chest is almost touching Jimin's back. He dwarfs the poor boy, with his comparatively narrow shoulders and small height. It's easy to speak close to his ear and make him shiver.
"You think you can try forcing it out on your own first, kiddo?"
Jimin stammers, flustered. "Wh-, H-how?"
"Arch your back. Like this." He places a guiding hand at the bottom of Jimin's spine, above his swishing tail and pushes forward, showing him how to bend. "Sometimes the milk can spray out on it's own if you do that," Namjoon says softly.
It is complete rubbish but Jimin follows his instructions and thrusts his chest out, arching his back and pushing his little breasts out into the cold bathroom air.
"Good boy. Just like that, little calf."
"It's not working hyung..."
Namjoon sighs as if disappointed. "Guess I'm going to have to get the milk out manually."
"O-okay hyung. Please do it."
"Relax for me, okay. Hyung is gonna help you baby."
The pet name has an obvious effect on the hybrid. Namjoon can see the gentle flush making its way up his neck from between the swells of his breasts.
"I have to massage them first. Since these stubborn little titties don't want to let their milk out, I'm going to help them relax," Namjoon explains, before slowly reaching his arms up around Jimin's small frame to cup each small breast in a hand. His hands seem to swallow them up and Namjoon's height is a great advantage at this moment, allowing him a delicious view of what he's doing to the boy's swollen chest.
Jimin's udders are plump, full of milk so they wobble prettily when he holds them and he can't help but jiggle them more than necessary.
This doesn't have to be sexual, Namjoon knows that. A family member could help milk a cow hybrid with little awkwardness if they use platonic techniques. Namjoon does not use these techniques.
He massages the supple mounds from the outside to the center, pushing the jiggly masses together and apart to stimulate the flow.
Jimin let's out the tiniest whimper and his fists clench at his sides. He's already so responsive, so sensitive and sweet.
“There sure is a lot of milk in these little guys. It's okay if I call them udders right? That's what they are after all.”
Jimin nods, face growing redder. He's embarrassed, too embarrassed. "Hy-hyung. You don't have to do this if you don't want to. I- you can just say no…"
"Don't be ridiculous Jimin. Look how full you are," he gives both udders a soft squeeze. "If I didn't find you when I did, these little titties might have exploded."
Namjoon continues to massage them gently and they feel so good in his hands, soft and heavy.
"Aw your udders must be so swollen and sore baby," Namjoon coos sympathetically.
Jimin makes a pained sound in agreement and pushes his breasts further into Namjoon's hands, a wordless plea for relief.
"Don't worry, hyung is gonna make you feel better, okay? I'm gonna take care of you, baby cow."
"Hyung please," Jimin begs out loud this time and it's breathy and shaky.
"So full Jiminie baby. Your back must hurt so bad," Namjoon says with sympathy. He has moved on to just the left breast, massaging the titty gently and smoothing his palm of the soft skin and pebbled nipple. He chose the fullest one to milk first because he's kind and he just wants to help the little hybrid.
"Y-yeah. How did you know?" Jimin's ears flicker against Namjoon's jaw and it's the cutest thing Namjoon has ever seen.
Jimin's cow ears suit him so well, they look too large for his head, make him look like he still needs to grow into them. Namjoon thinks they'd look really nice with a big ring piercing. Maybe a tag, to say who he belongs to, like a proper cow.
"Because you're so tiny baby cow. Carrying all this milk is too much for your small body. I'm glad I found you when I did Jiminie. Cute little cow like you shouldn't be in so much pain."
Jimin's tail is swishing around and Namjoon can feel it moving against his crotch. He is definitely hard and he is so fortunate that Jimin's back is to him because there is nothing subtle about his boner.
"Don't worry baby, Hyung is going to get all this sweet milk out for you so it doesn't hurt anymore okay?"
"Thank you hyung," Jimin says shyly, genuinely.
"You're welcome baby."
Namjoon works the boy's tits over for a while longer, squeezing and massaging and rubbing the soft mounds to his heart's content.
"Alright buddy, you want to spill your milk onto the floor or do you want hyung to move you to the sink?"
"The- the sink p-please hyung," Jimin says softly.
Namjoon moves the topless hybrid over to the sink, above which is mounted a large mirror - the sympathetic offer Namjoon had made to stand behind Jimin now becoming redundant because of the mirror.
Th reflection lets Namjoon see Jimin from the front, see his full expanse of soft skin, his little udders in Namjoon's hands with their peaked nipples, his chest and neck and face flushed a delicate pretty pink. His cow ears are flicking about and his eyes are watery as he waits for Namjoon to continue.
Namjoon's thumbs rub at the cute nipples until they harden. And when they're hard as pebbles, he flicks at them and Jimin yelps cutely.
"Sorry buddy, I just gotta get these cute little nips ready for your milking."
"O-okay hy- ah!" He yelps again when Namjoon pinches the left nipple and pulls. From Namjoon's angle, he has a clear view of the little calf's chest heaving, looking beautifully debauched.
"Good boy. You're being such a good little cow Jimin."
Namjoon notices Jimin observing his own reflection and he can't help but look too. The little calf looks obscene, mouth swollen pink and pupils blown and the little nipples Namjoon has been teasing look sore and sensitive, swollen from all the flicking.
Jimin blushes harder at his reflection and closes his eyes.
"Everything okay Jimin? Do you want hyung to stop?"
"No hyung. Please. Just… just milk me," Jimin's voice is breathy. His eyes are shut tighter and he nibbles on his lower lip, bracing himself for Namjoon's arousing touches.
"Aw Jimin…this little titty is being naughty isn't it? So stubborn, not letting its milk out," Namjoon teases and he flicks at the left nipple like he's preparing a syringe. And… needles are an interesting thought. Jimin looks so innocent, his skin is so peachy and soft but pinkened by his incessant blushing. Namjoon imagines leading the little thing around by a chain hanging from two sweet rings through his nipples and he nearly comes up the spot.
Jimin whines cutely and he steps closer to the sink, pressing against it. And that's when Namjoon notices that the poor boy is attempting to hide his hard on. It's so small though, that Namjoon's not sure he would have noticed anyway. Jimin tries to hide regardless.
"Ask nicely Jimin. What do you want hyung to do?"
"Milk me hyung," he says softly. His ears are flat against his head and his tail is hanging low between his legs. He's so embarrassed and shy and Namjoon is thriving on how pretty it makes him.
"Milk your what?"
Jimin hesitates. His chest is pink and his fists are clenched tight and he can't open his eyes because he'll have to look at Namjoon. "M-milk my… my udders hyung. Please."
"Good little cow. Hyung's gonna make you feel so good sweetie pie. Poor baby cow can't milk himself."
Jimin shudders, whimpers, his little titties have undergone so much fondling and they're still practically bursting. "Nu-uh. Don't know how," he whines, embarrassed and needy.
"That's right Jimin. Poor helpless little calf. Don't worry baby. Hyung's got you. Hyung will give you what you need."
"I- ah-" Jimin can hardly form words as Namjoon finally takes the left nipple between finger and thumb and pulls back towards his chest before tugging away, coaxing the stubborn milk out of the full breast.
The first jet of milk comes out with such force that it sprays straight onto the mirror and runs down in white streams. Jimin's moan of relief is orgasmic and delicious. He moans like he has a cock inside him, moans like someone is sucking on his tits.
And Namjoon is aching with the desire to pull the boy's sensitive little nipple up to his mouth and suck. Jimin would cry from the feeling of Namjoon pulling the milk from his breast with suction, forcing it out with his mouth. It would be too much for the little guy.
Namjoon repeats the action, this time angling the small udder more towards the sink below.
A beautiful stream of milk falls from his nipple, white and clean and delectable. "You smell so sweet Jimin. Smell like milk, like a little baby."
Namjoon works in a rhythm, pulling on the breast with carefully skilled motions to get the milk out and Jimin throws his head back against Namjoon's shoulder and groans in relief as he's finally emptied.
"You like this Jimin? You like having hyung's big hands on your tiny baby udders?"
"Hy-" Jimin's words are cut short by an erotic moan that goes straight to Namjoon's dick and makes it twitch. Jimin is too naive to know what he's doing to Namjoon, doesn't know how angelic and dirty he looks like this. His small breasts are shiny with milk now, wet all over, and Namjoon can't stop thinking about licking it all up.
"You look perfect like this Jimin. If only the other guys could see you. This is what you're made for little calf." Jimin moans and whines and pushes his udder into Namjoon's touch.
"Are you putting on a little show for me Jimin? I know you are. You want me to tell you how pretty you look, don't you, little calf?
"N-no I wasn't-" Namjoon's pinches his nipples hard and Jimin lets out a sweet sweet cry.
"Wasn't what? Purposefully showing off your little udders around the dorm? Always touching your tits while you knew we were looking?"
"Oh- oh god," Jimin gripped the edge of the sink as if his knees were about to give up.
"Well you do look pretty Jimin. Covered in your own milk with your little cock all hard in your pants. So so pretty baby cow," Namjoon croons into Jimin's neck. Oh, he wants to bite the little ear that's flicking about in front of his face and make the boy scream.
"Didn't mean to…I'm sorry I didn't mean to get hard Hyung," Jimin sobs.
"I know baby cow, I know. It's alright. Hyung understands. You can't help it. It feels good because this is what you're made for, little calf."
Namjoon moves his attention to the other breast, gives it gentle squeezes and then makes Jimin look. "Your full titty is so swollen Jimin. Look at the difference! Look how stretched it is baby," Namjoon hums in sympathy and then teases the nipple by drawing circles around it that makes Jimin squirm and pant.
"You want Hyung to milk your other udder baby cow?"
"Yes! Yes please hyung! Please! I need it!" Jimin cries, shameless now with his one aching breast.
"Look at you. Finally becoming a big cow, aren't you Jimin? A proper cow made for milking," Namjoon praises as he finally begins to pull milk from the right titty. It's so cute and wobbly. The left is smaller, almost flat now, and Namjoon misses it already.
When they're done, there's milk everywhere. On Namjoon's hands, all over Jimin's front and on his pants.
Jimin says a quick thank you and makes the hastiest exit Namjoon has ever seen, only stopping to pick up his abandoned shirt to cover his exposed chest as he flees the bathroom.
He's probably gone to take care of his boner in privacy and Namjoon resigns himself to doing the same, coming into the sink with loud grunts.
__________
The next time Jimin approaches Namjoon and shyly asks him for his help, Namjoon is too busy to help. Says he'll be able to help when he gets back from class and leaves. But Jungkook overhears and hesitantly volunteers his services.
Jungkook is a lot harsher with Jimin's nipples. He pinches really hard when he tugs but he gets the milk out in the end, despite the technique.
He also shares some important information with Jimin about milking customs that Jimin is very surprised to hear.
"You know, it's customary to speak respectfully to someone who is helping to milk you, Jimin."
"Really? I didn't know that Kookie. Namjoon-hyung never told me that." Jimin says, embarrassed.
"He probably didn't want to overwhelm you since it was your first time." Jungkook says as he smooths his hands up Jimin's sides, enjoying the feeling of his soft bare skin.
"Uh… is there something specific I'm supposed to say, Jungkookie?"
"Just call me sir for now. I think that will do."
"Oh." Jimin blushes and looks at the floor. It's hard to call anyone sir but it's even harder to call the maknae such a term of respect.
"Okay, Sir."
Jungkook chuckles. "That's good Jimin. You're doing good, little calf."
__________
It isn't long before everyone in the house has had a turn to milk the hybrid and he thanks each of them at the end with a polite, "Thank you for milking me Sir," that has them struggling to control their urges.
He wouldn't produce so much milk if they didn't milk him so often, encouraging milk production as if Jimin has a young one nursing on his breast. Jimin doesn't know this and they continue to milk him several times a day until he is failing all his university classes from lack of attendance.
But the little calf doesn't seem to care. His skin is pulled taut as his udders grow, stretching and stretching to accommodate all the milk he's producing now.
His tits are so large now that he doesn't really want to go out in public, he doesn't want anyone to see him like this, swollen and leaking most of the time, embarrassing wet patches on his shirts.
__________
"Look Jimin! We got you a present to celebrate your coming of age!" They're all there, with Seokjin holding out a box and a gift bag.
"What? Really?"
"Well, one is a present, the other is tradition," Seokjin elaborates.
"Present first!" Taehyung exclaims, clapping his hands together with pure excitement.
Jimin is confused to say the least when he first pulls it out of the gift bag. "Wh…"
"It's a bell!" Namjoon says. Jimin can see that and he squints at it, holding it up in confusion. It is very big.
"It goes around your neck," Seokjin explains. "Here little calf, let hyung help you."
The bell is attached to a thick leather strap that Seokjin curls around Jimin's neck and buckles closed. The bell rests on his chest, just above the valley between his udders, and makes a dull clanging sort of noise when he moves. He blushes and thanks his friends kindly for the jewellery.
The next present is even more confusing.
"It's tradition for cow hybrids to start wearing these when their lactation starts," Namjoon explains. "Here, hold your hands out."
Jimin's hands have to be in fists to fit inside it and Namjoon helps him to pull both of the things on, zipping them up on the sides.
The gloves are hard as bone on the outside but they aren't heavy. They're fully black, have a flat circular edge to them and make a light clopping noise when he rests them on the table.
They are hooves, he realizes, with humiliation and he wants to get them off but he can't and it's tradition, they explain, so he's supposed to keep them on.
He thanks them for the gift and spends the rest of the day trying to figure out how to do normal things.
__________
They begin to collect the milk in large glass jars and sell it for a high price, so they aren't very pleased when Jimin is leaking and milk is going to waste.
Jimin's tits leak all the time, small droplets of milk pearl at the tips of his nipples continuously and it's not good for business.
So they buy nipple clamps and attach them tightly to his dripping udders to make sure that none of the precious milk goes to waste. The clamps pinch onto his nipples and then, a part like a cap screws on over the top to stop any milk escaping.
His breasts continue to expand from all the milk he is producing and can't let out. It hurts more than ever but Jimin can't get the clamps off with his flat hooves and he's too embarrassed to ask them to take the clamps off and milk him.
His breasts, despite how full and stretched they feel, never droop from the weight of the milk. Instead, his breasts jutted forward, looking very unnatural in their shape and size - by human standards at least. For cows hybrids it was normal to have basketball-shaped tits that seem like they are trying to attract attention. They are still soft though. And they still jiggle prettily like they're beckoning people to milk them and drink from them. The most tempting depraved treat.
Eventually they are too big and hurt too much for him to do much other than lay down on his back and groan, waiting for someone to come to milk him and relieve the ache. His tits poke up into the air, resting on top of him like watermelons and eclipsing the view of his face from below. In fact, when he lies down, he can barely see anything else beside his massive udders in front of his face.
The more time Jimin spends in his room, the more his friends try to make it more comfortable for him.
First they move out most of the furniture he isn't using anymore. His desk, computer, set of drawers, side tables, all are gone. In their place, is all the milking equipment, so Jimin won't have to go far for his milking.
When they eventually give in and buy a fully functioning milking machine, along with massive jars to store the milk, they buy a set of wooden stocks as well.
"It will be more comfortable for you this way," they tell him when he first blanches at the sight of the intimidating contraption.
There are three holes in the stocks: a large one for his head and two smaller ones on either side for his hands. The stocks are at waist height which means that Jimin has to bend over at an inappropriate angle to be locked into the heavy thing.
And as unnecessary as it is, they do lock it. When they pull the top half down over his neck and wrists, there's an ominous creak from the hinges like the stocks are medieval. And then they pull the latch closed. His hooves wouldn't allow him to open the latch anyway.
The second part of the restraining process comes as a complete surprise to the hybrid. They pull his ankles apart, spread his legs and shackle them to the base of the stand. He whines, tugs at the restraints, confused.
They proceed to cut off his clothes. He doesn't need them anymore after all and they'll just get wet and uncomfortable with milk.
Once he's hooked up to the milking machine, suction cups creating a vacuum around his nipples, they switch it on and watch Jimin buck in the stocks from the extreme stimulation to his sensitive udders. It isn't long before his little cock his hard from being milked and he whines with desperation, unable to touch it or help himself but needing to so badly.
"Don't worry, baby cow. Your hyungs got something to help you," they say, as they wheel the massive fucking machine up behind him. He can't see it, so he cries out in surprise when he feels something easing its way between his ass cheeks.
"This dildo is gonna go inside you to keep you nice and horny, baby cow. Makes the milk taste better, you see."
Jimin moans as they push it into him and it sparks pleasure he hadn't anticipated, hitting a special place inside him that makes his cock leak and makes him see stars. He complains with a groan, perplexed and stimulated beyond his senses and he still can't touch his cock.
"Don't worry, you'll learn to come on just the dildo little cow," Hoseok hums sweetly.
Jimin whimpers as the machine fucks into him faster and he has nowhere to go. It forces his way into him while the suction machine forces milk from his engorged udders. It's pain and pleasure like he's never experienced and all his roommates file out the room to leave him to his milking.
The process of milking makes happy hormones rush through Jimin's bloodstream like a drug and the fucking machine only adds to the strange euphoria. It isn't long before Jimin is docile from the pleasure, pliant like a cow should be.
Sometimes they replace the fucking machine with their own cocks, spilling their cum inside the little calf whenever they need relief. Most times it seems like Jimin doesn't even notice.
He does notice, however, when they unplug the milking machine and instead provide suction to his tits with their mouths, latching on and sucking to their heart's content. He loves it, and whenever someone enters the room, his eyes follow their lips eagerly, hoping. And they chuckle at him, his needy gaze too easy to read.

On a day no different from the others, Yoongi walks in to to find someone has left Jimin locked in the stocks, suction cups attached to his udders, but hasn't bothered to switch on the machine.
The hybrid's breasts look painfully engorged, hanging swollen and sore from the stretch.
"Do you need to be milked Jimin?" Yoongi asks, as he approached the trapped little cow from behind.
"Yeah," he groans, tail swishing.
"Are you gonna ask?"
"Uh, p-please can you milk me, Sir? "
Yoongi shakes his head and tsks, disappointed. "That's not how cows are supposed to ask. Do you know what cows do when they want to be milked? "
"What?"
"They moo. Can you moo for me Jimin?"
"Hyung, you know I can't do that! D-don't be r-ridiculous," the hybrid stammers, uncertain.
"I guess I'll come back tomorrow then."
Yoongi pulls the suction cups off and begins to fix the clamps onto Jimin's tits, screwing on the tiny cap and trapping all the milk inside.
Yoongi doesn't even give Jimin a chance to change his mind. He simply turns around and exits the room, leaving Jimin behind with his painfully swollen tits, crying for Yoongi to come back.

When Yoongi returns the next morning, Jimin doesn't hesitate. There's no greeting, no exchange of words, Jimin just lets out a long low desperate moo. It sounds more like a groan but he does it again and again, a frantic plea to be allowed to release the milk inside his tits.
"Sounds like someone finally understands what he is," Yoongi says sweetly.
And Jimin groans in pain and arousal and frustration. He'd been here for so long that his udders look unfathomable in size. He can't believe he can swell so much, can't believe how much milk he made.
"Alright alright, relax sweetheart. We'll get you milked in a second," Yoongi drawls, petting Jimin's bare bottom below his swinging tail.
"First let's get your favorite toy up and running, Yoongi says." He adjusts the fuckine machine, plugs it and let's it run. And Jimin can only moo. It's an expression of pleasure, a desperate cry for release and confirmation of his purpose.
Yoongi rewards him with a single stroke to his cock and Jimin lets out a pained animalistic cry, not having been touched there in so long that he almost can't comprehend the sensation. He thrashes around in the stocks, mooing, hoping to be touched again but Yoongi ignores the bucking easily.
"Let's get your pretty udders hooked up to the machine sweetheart." Yoongi says, giving the hanging melon tits a gentle swat. It makes Jimin let out a cry which quickly reverts to a low moo.
"That's it my dumb little cow. Keep mooing. Keep mooing for me. Show me how much you want to be milked," Yoongi orders and Jimin does. He moos and moos and it's humiliating and degrading but he doesn't care anymore. He's a dumb cow and he needs to be milked.
Yoongi places the suction cups onto Jimin's nipples and the hybrid cries out from the dildo ramming into him and the feeling of his near-bursting udders.
The man flicks the machine on. It starts to whir as it pumps and Jimin moans in ecstasy as his nipples are sucked on by the machine.
He moans and moans, one inescapable machine fucks into his hole while the other pulls on his tits. But his poor cock is untouched and he's so desperate and overwhelmed that he's not sure anymore whether he's mooing or moaning or both.
He doesn't think he could speak anymore if he tried.
"That's it, little calf. Try and enjoy it. It's all you're good for now."
