Cow Hybrid Binsung
Welcome to my first post, sorry the ending is incomplete this has been in drafts for 2 years now and I’m still weird about writing smut 😭
Warnings: Weight gain fic, male lactation
…
Jisung had always been insecure of his cow hybrid status. He always tucked his tail into his pants, and hid his ears and tiny horns under beanies and hats. The other issue was cow hybrids tended to be… bigger, gaining weight easier than the average person. So he'd worked tirelessly to keep himself thin.
It served a dual purpose as well, one was to keep people from realizing his true nature, the other to keep his udders from truly blossoming and producing milk. It was tough trying to maintain his image but he did so out of fear. The hybrid genes had skipped his parents so they had been average humans, and upon seeing the little horns sprouting out of his head, they’d been quick to slap a beanie on him and deny mentions of it to any and everyone else. This same thinking had completely overtaken Jisung too.
That is, until he met Changbin.
Changbin was easily the largest cow hybrid he’d ever met, in every sense of the word except height. He came into the coffee shop nearly every day, huffing and puffing through the doors as he could just barely squeeze through, his cheeks red from the exertion. He wobbled his way up to the counter, his belly and titties bouncing the whole way, and Jisung couldn’t help but be entranced. Not to mention the absolutely adorable way he’d squeak out moos when he was eating something particularly tasty.
Jisung found himself developing a crush on Changbin (partially out of genuinely liking him and his sweet personality, partially from a sense of longing to be like him). And so, Jisung did the only thing that made sense to him.
He put his all into gaining weight.
Jisung had always hated the strict workout routine his parents had forced onto him from such a young age, and he much preferred lounging and playing video games. Still, they’d preyed on his anxieties, reinforcing the idea that no one would be accepting of his hybrid status, especially as such an unconventional one as a cow hybrid rather than the more common cats and dogs. Now though, living in an entirely different country, and seeing Changbin live his life so freely, Jisung felt the desperate need to follow in his footsteps.
So, Jisung started simply with using his employee privileges to sneak himself snacks while working, then dragging chairs for when he was on cashier duty. And while that had helped the first layer of pudge appear, he simply wasn’t gaining fast enough.
Jisung couldn’t help it, imagining himself big enough to rival Changbin’s own bulk, his own boobs filled to the brim with milk. Though now, he’d sadly poke at his own chest, awaiting the day his milk ducts would finally produce something.
…
The thing Jisung hadn’t really considered in his eagerness was that he’d need to order a size up in uniforms.
The button up shirt was absolutely clinging to every roll of his body, and his boobs looked like they were one deep breath away from ripping his shirt open and escaping. Thankfully his boss just wordlessly ordered him a size up and tossed him an apron to tie over so it wasn’t as noticeable. Weirdly, his chest had been aching in an unfamiliar way, not super painful, just full.
During the slow periods Jisung couldn’t help but think about Changbin seeing him in this state. He wondered what his other cow hyung would think, if he’d be impressed by just how quickly Jisung had tried to follow in his footsteps. Maybe they could share a meal together! Maybe they would bond over their cow hybrid status. And maybe Changbin would let Jisung drink some of his milk.
Jisung sighed, no time to focus on silly fantasies at work.
Unbeknownst to Jisung though, is that as he was daydreaming and snacking, his milk had decided then and there that it was going to come out … just as Changbin walked in for his afternoon snacks.
“Hey welcome to The Divine Cafe, what can I get you?”
It’s in that moment, when Changbin begins rattling off his (very, very) long order that Jisung feels the wet shirt sticking to his skin. It’s then he looks down to see the front and that his own milk has stained his shirt, and the apron on top. Jisung blushes furiously, scribbling furiously to get the rest of the order written down. Meanwhile, Changbin finally moves his gaze away from the menu and looks at the person actually serving him, and his polite smile turns to a look of concern.
“Um, if you need to take a break to milk yourself that’s fine, I can wait!”
Jisung looks panicked, confused, anxious, proud because it’s his first milk! But also it’s his first milk and he’s not prepared, he doesn’t know what to do, where to begin, and his breathing starts to get heavier when he feels a hand on his shoulder.
“Do you need help?”
And Jisung looks, really looks at Changbin with his crop top that has his belly pouring out the bottom, his moobs stretching the fabric to the max, his curly hair so long it nearly covers his horns, and lastly the concern in his eyes, and the tentative smile he has that just highlights his chubby cheeks.
“I-I don’t know, I mean how would you help me?”
“Well you’re past due for a milking, I can’t believe you’d come to work so full of milk.”
Jisung looks down, “It’s my first milk, I didn’t realize.”
Changbin clenches his jaw, “You need someone to help you then.” He said it so confidently, resolutely, that Jisung had no choice but to agree. Not as if he would deny Changbin when he’s been lusting after him for months now.
Jisung’s manager scoffs at the site of them, but gives them the key to the breakroom regardless. “Don’t leave milk stains on the couch” is the only warning given and so they both take that as the go ahead it is.
There’s not much in the breakroom, but luckily there is a couch big enough to not collapse under their combined weight.
Jisung peels the apron and shirt off with little spectacle, the wet clothes being more uncomfortable than any embarrassment he had over his partial nudity.
“So how will it work?” Jisung asks.
To which, Changbin simply replies, “Hands or mouth?”
Jisung exclaimed, “Mouth?”
Though Changbin seemed to take that as his choice and not the question it was. Still, as Jisung felt Changbin’s hot breath come closer to his nipples, he couldn’t find it in himself to object.
Changbin first licked at Jisung’s nipple before beginning to truly suck the milk out. And Jisung? Jisung wasn’t prepared for the sensation of feelings of it all, the bliss of the release of milks, the endorphin high, and the eroticism of seeing Changbin sucking on his nipples so hard, that it felt like they were connected straight to his dick.
How could he have ever denied his cow when this is how good it felt?
