Yoongi always hated his cow genetics as he produced milk from a young age.
In addition to having an adorable belly, his moobs were like those of a woman, he wore a bra since every week his tits were filled with milk.
This all started when Yoongi turned 18, he hated every moment while being, he didn’t want to do it, but his pain would only increase if he left the milk inside him one more day.
So he asked his family to buy him a milking machine, it hurt, but it was worth it to feel empty and without any pain.
After his family accidentally tasted his milk at a family meal, they implored him to sell it, as it was more delicious than the others.
So we go back to the present, where Yoongi was taking out his fourth bottle of milk, he still had a lot of bottles to take out, but it would be worth it in the end.
It had been only a few weeks since that family meal and now the village had become addicted to the milk it produced, but Yoongi, a bit chubby, could not produce the amount of milk that the entire village needed, so his parents gave him more food and it had worked.
Now Yoongi's belly hung from the waist of all his jeans, his cheeks were adorable and very plump, his thighs brushed against each other when he walked, his butt was large and his arms somewhat chubby.
But it was worth being a little chubby to see the money he received, he was famous in the town and in those nearby.
He could not complain, at only 22 years old he was known by everybody and they had recently made him a proposal to expand the distribution of milk to other towns.
But Yoongi refused, claiming that he would have to gain more weight and that he didn't want it at the time, he still had to find someone who would want him that way.
The following weeks he was so busy with his new job producing milk that he did not hear about the new families who had moved to the city.
So he woke up that morning excited because it was his day off, causing his belly to bounce from the movement and grunt with hunger.
Yoongi had already adapted to his weight, he was not complaining, he could eat whatever he wanted.
So he went downstairs to the kitchen and made some pancakes, with scrambled eggs and some greasy bacon.
It was true that he had a balanced diet, but he only followed it when he had to produce milk, he was grateful that his instincts were not so strong as to only eat salads and water, since he would spend his time producing milk and he did not like the pain that it caused.
When everything was ready, he sat down and began to eat with relish, thinking about the things he could do that day.
----
He entered the supermarket pushing the cart, he was not a fan of shopping for groceries, but he rewarded himself by buying his favorite sweets.
So he went to the candy section, while answering the greetings of the townspeople.
At that, he went through the dairy section noticing that the only milk they now sold was Yoongi's, making him smile proudly. Only he didn't notice the road and hid cart collided with someone’s.
"I’m so sorry!" Yoongi saw the boy's sad face, who was looking at the milk spilled all over the floor.
"Don't worry, I'll have another one" at that moment they exchanged glances and Yoongi blushed, the boy was handsome.
"I-Is it you?" Yoongi tilted his head and the boy pointed to the milk label, it was him but like a cartoon, he blushed and nodded.
When he saw the boy's smile, he couldn't help but smile in the same way. "It can't be, it's you, woah .." The boy approached him with his big bright eyes and admired him closely, making Yoongi blush at the cute boy's attention.
"I just want to tell you that the milk you make is absolutely special."
"T-Thanks" the boy smiled and spoke once more.
"By the way, my name is Jungkook, I'm new to town" he extended his hand and Yoongi took it while his lips parted.
He did not know there were new residents, the good side of this was that this adorable boy had arrived.
"Oh, I was not aware of that" they both laughed nervously separating their hands, which had been held together for a few seconds.
"Yes ... We arrived a few days ago and just yesterday I had the opportunity to try one of the best products from here" he said lifting the new bottle of milk he had taken, making Yoongi blush again.
They continued talking for a few minutes until they said goodbye hoping to meet again.
----
That had already been two weeks ago, the cow hybrid had had a lot of work so he did not run into him on any occasion.
But that day, again, he was free so he decided to go to the park to get some air.
He took his things and left his apartment, he walked to the park that was about two blocks away and sat on a bench that was just under a large tree.
Yoongi began to admire the people and noticed something strange, they were all plump, even if it was minimal, they all showed a little more weight on their bodies.
That surprised the hybrid, since everyone in the town had always been slim, despite their genes, they kept very fit, so he was somewhat puzzled and continued to see the park until a voice interrupted his observation.
"Yoon!" The pale man visualized Jungkook trotting towards him, causing Yoongi to show a gummy smile.
"Hello Kook, what brings you here?"
"Nothing in particular, I just came to walk a bit, being at home is kind of boring when your internet is cut off" the two laughed and continued talking pleasantly.
They had hit it off very well, plus they had several themes in common. Only they were interrupted when they felt a few drops of rain fall on their faces.
The two ran in the direction of Yoongi's house when the rain intensified. When they arrived, Yoongi sent Jungkook to shower, he didn't want him to catch a cold.
When he got out of the shower, Yoongi lent him some clothes and also went in to shower.
After he changed, he went down to the living room and they decided to put on a movie when they saw that the weather was getting worse.
Yoongi got up from the couch and went to the kitchen to prepare some snacks for the movie. He had recently done the shopping so he had plenty of food.
He took out some of the sweets that he had bought along with some soft drinks and returned to the living room, noticing how Jungkook was with a blanket waiting for him.
When they exchanged glances they smiled shyly and played the movie once Yoongi sat down next to each other.
The movie took a back seat to Jungkook as he lost himself admiring Yoongi's gorgeous features. He blushed when he noticed how he looked at him for a few minutes, so he looked away to another part of the room trying not to disturb the older one.
Once the movie was over, the two of them packed everything up and went to the kitchen to make dinner. It was already dark and the rain had only intensified, so Yoongi invited Jungkook to stay at his house that night. Jungkook accepted, very excited, with a big smile on his lips.
"Have you noticed the recent weight gain of the townspeople?" Jungkook stopped chopping the mushrooms to look puzzled at Yoongi.
"Weight gain?"
"Yes, everyone in the town has always been very thin and now everyone has a little more weight" Jungkook tilted his head and fixed his gaze on his body, he was fine but he didn't see a problem so he shrugged.
"I hadn't noticed"
"Neither had I, I'm not saying it's a bad thing to gain weight, I'm chubby, it's just very strange" Yoongi said putting noodles in hot water.
"Maybe their way of thinking has changed" he saw Yoongi nod and they continued preparing everything.
When everything was ready, they put it on the table and began to eat, talking quietly about various topics.
"Ow! Everything was delicious, but I'm very full" Jungkook rubbed the small swelling that protruded from his belly and Yoongi did the same, only this one, rubbed his hard belly.
"So am I, but it was delicious" the two agreed and went to Yoongi's room. There was only that room and his study, but he could not leave his guest on the sofa, so once inside, the two of them changed into more comfortable clothes.
Yoongi with his tight pajamas and Jungkook with pajamas that the older one lent him.
"Very well, in the closet there are more blankets in case you need and here is the bathroom" he spoke while walking to the mentioned places, giving him a little tour of the room.
"With that said, I'm leaving, rest well" before he even advanced Jungkook took his hand.
"Where will you sleep? Didn't you mention you only had this bed?" Yoongi turned and saw the younger's big eyes.
"In the study, there is a sofa" Jungkook denied and dragged him to the bed, "Come on lie down, we will sleep together" Yoongi blushed but did not refute at any time.
The two of them went to bed somewhat nervous because of the closeness, "good night"
"Good night, rest" Jungkook spoke in a whisper.
A few minutes later, the two fell into a deep sleep.
----
"A-Ah" Yoongi moaned softly as he felt a familiar pain in his chest, which meant only one thing, he had been filled with milk during the few hours that he slept.
He had to milk himself, but he did not want to wake the boy who was next to him in a deep sleep so he turned very carefully not to press his moobs and when he found a comfortable position he went back to sleep.
Only an hour later Jungkook woke up to feel something warm on his back, so he turned drowsily and touched the sheets in surprise.
When he noticed that they were wet from something, he tilted his head and saw where the liquid was coming from.
Jungkook opened his eyes and before confirming what it was he approached the sheets and sniffed a little.
When the smell of milk and honey passed his nostrils Jungkook groaned. That day he had not had his usual glass of milk in the morning.
Jungkook saw that Yoongi's shirt was soaked and licked his lips. He knew he shouldn't, but in just a few weeks he had become addicted to that milk.
His mother only gave him a big glass in the morning, leaving the poor boy wanting a few more.
He debated for a few minutes until he heard a groan of pain, when he looked at Yoongi, he could see the expression of pain that reflected his face.
His parents had taught him that when cow hybrids produced milk they suffered a lot, since they needed to get it out immediately because it was beginning to be very painful and uncomfortable for the person. Jungkook pouted when he heard another groan of pain from the older man.
So he cursed in a whisper and walked over to Yoongi. He carefully unbuttoned his shirt and made himself comfortable. He realized that Yoongi was a heavy sleeper and once he was comfortable he took the hybrid's swollen nipple between his lips.
When the first drops of milk touched his tongue he moaned softly, the milk was warm and tasted delicious. Without avoiding it, Jungkook got closer to Yoongi and sucked faster, feeling the milk settle in his stomach.
He was moaning with pleasure at how delicious that milk was, so he drank more quickly, causing a few drops of milk to come out of the corners of his lips.
After a few minutes he dislodged Yoongi's nipple with a gasp and ran his hand over his swollen stomach. He lay on his back as his hands roamed the expanse of his belly, trying to calm the pain that was beginning to emerge.
But without a doubt it was the best sensation he had felt in a long time, when his fingers tightened somewhere on his belly, he burped something hard, making him blush and look at Yoongi.
When he saw that he was still asleep, he sighed and kept rubbing his belly, releasing the burps each time he pressed on different parts of his stomach.
When he felt his belly softer he relaxed and buttoned Yoongi's shirt again. He settled in with difficulty, still feeling quite full, and fell asleep almost instantly.
----
The next morning Yoongi woke up strangely without any pain, so when he noticed the milk stains on the sheets he was worried about what Jungkook would say.
But when he noticed little drops of milk at the corners of his lips and the boy's swollen belly, he blushed. He looked down at his boobs and noticed that one of his nipples was red. Yoongi smiled proudly and went to the kitchen quite happy.
He knew he should reprimand the minor, but when he saw him he couldn't help but look at him with dreamy eyes, he looked so adorable.
Besides that he had a slight attraction to the wolf hybrid. So he started making breakfast with a little plan in mind.
----
Jungkook opened his eyes when the sunlight hit them directly. Causing him to wince.
He rubbed his eyes before opening them and noticed that Yoongi was not in bed.
He could also notice that it was still raining even though the sun had risen.
He got up from the bed but fell into a sitting position due to the sudden weight he felt on his belly.
He looked down and noticed how his abdomen was still swollen from last night, causing him to blush.
He went down the stairs trying to cover his belly uselessly and sat in the dining room waiting for Yoongi.
Who came in just a few minutes later with various exquisite dishes, causing Jungkook to swallow the accumulated saliva in his mouth.
Everything looked and smelled so delicious.
"Well, enjoy" Jungkook stared at the older man in confusion.
"Won't you have any of this?" seeing that Yoongi shook his head cocked.
"No, I had breakfast a little while ago, so enjoy" Jungkook blushed when the older one gave him a beautiful smile.
So he picked up a fork and began to lift the greasy pieces of bacon to his lips. He groaned at the great taste of these so he grabbed some honey pancakes and popped them into his mouth, feeling how soft and fluffy they were. He went on like this, interspersing the bacon with the pancakes until the fork met the pottery on the plate.
He blushed as Yoongi got up from his seat and brought him more dishes that looked extremely delicious. So he didn’t question anything and dug into the plate that had kimchi with tteokbokki on it. He felt the fat from the cheese run down the corners of his lips, but he didn't care, it was so good that he didn't realize it, absorbed in the magnificent flavor of the dish.
So he didn’t notice the look Yoongi was giving him either. The pale man got up quietly and went to lock himself in the bathroom to check the other facets of his plan.
Once he was sure that everything was going according to plan, he left the room to find several empty plates that made his lips rise in a proud smile. And he felt his chest swell with glee at seeing Jungkook with his swollen belly and his face in a mess.
"You're done?" Seeing how Jungkook nodded slowly, he knew it was time to continue with his plan.
"But you didn't drink anything, do you want something in particular?" Jungkook fixed his eyes on Yoongi and blushed as he remembered the events that had happened in the night.
"I-I would like some l-milk" Yoongi nodded excitedly at that, he was expecting that answer, so he approached the table and took a napkin to wipe Jungkook's lips.
The younger one blushed violently at the proximity of the pale one, feeling his heart beating wildly within his chest.
"Ready" Yoongi whispered, separating himself from Jungkook's face.
"You want milk right?" Seeing how Jungkook nodded blushing, he approached the stuffed boy again and sat on his thighs, drawing a surprised gasp from the boy.
Yoongi smiled mischievously and hit his soft belly with Jungkook's hard, eliciting a groan from the younger.
"Fine Jungkookie, take your milk" Yoongi took his breast and raised it a bit, waiting for Jungkook's reaction.
And the aforementioned could only blush and let unintelligible monosyllables leave his lips. Yoongi laughed and spoke,
"Did you think I wouldn't notice that one of my boobs was out of milk?" When Jungkook nodded nervously, Yoongi smiled even more and with his other hand pinched the other's cheek.
"It was very obvious Jungkookie, but now my other tit hurts, and you want milk, so drink whatever you want" He didn’t need to say more to get Jungkook to stop licking his lips and put them on Yoongi's nipple, starting to suck desperately.
The pale one chuckled, seeing how Jungkook looked like a cute baby, and couldn't help but stroke his hair. Meanwhile, Jungkook could easily tell that he was in heaven.
The milk tasted even better than a few hours ago and he couldn't stop drinking even though he was already too full.
But he was encouraged by hearing the praise and cheers that Yoongi gave him. So he ran his hands over Yoongi's broad hips and sucked, determined to finish off all the milk.
An hour later Yoongi stopped feeling pressure on his nipple, when he saw Jungkook asleep and still attached to his chest made him feel very proud.
"Little glutton" he stroked the strands of Jungkook's long hair, trying not to move much due to the moans that came from his lips.
Yoongi looked down and was surprised to see a hard belly in addition to his own. The pale one lowered his hand and let out a gasp when he felt some softness in the minor's belly.
He couldn't have gained a few pounds!? Could he!?
Yoongi felt his stomach contract with excitement, so with his plump hand, he began to distribute caresses on the chunk that peeked out of the pajamas that he lent Jungkook.
He felt like heaven as he felt his tummy go soft and Jungkook burped when he ran his hand over different parts of its hard dome.
Yoongi couldn't stop looking at the boy, he was fascinated, excited and above all, in love. With those thoughts, Yoongi continued to take care of Jungkook until he was sure that his belly had become soft and there was no longer any pain.
So with a pain in his chest, he had to rouse the youngest from his eating coma.
"Jungkookie come on, wake up" Yoongi stroked his hair while whispering that into his ear.
Jungkook opened his eyes sleepily, feeling somewhat dazed, but mostly stuffed.
"Come on darling, get up" Yoongi spoke sweetly as he gently pulled himself off the other's lap and stretched his arms to help the brunette who just nodded without knowing what was happening.
Yoongi took him from his swollen waist and pushed him slowly, making Jungkook burp, the older only brought one of his hands to his belly to continue rubbing it while the other covered his lips to try to silence the burps.
When the pale man made sure that the younger supported his new weight, he took him back to the room, where he laid him down and tucked him in.
He kissed his forehead and left the boy asleep with his hands in his new softness.
Yoongi went down to the kitchen, took out a salad and a lot of water ready to produce milk.
He knew he should discuss this with Jungkook, but he looked so adorable that Yoongi just wanted to see him fill up again.
Besides that, his heart had been agitating for the boy for a few weeks already, he could make him fall in love and finally have a partner.
So he dug into the salad with enthusiasm, ready to refill the boy and win him over to make him fall in love.
