All his life Izuku was told one day he'd have to mate with a bull and have calves to provide milk for the farm. His mother would brush his hair and tell him this in hopes of preparing him for the eventuality.
Izuku is the only calf his mother ever birthed that was a heifer, all his siblings before and after have been bulls. So he's never met his older siblings, they were sold off for breeding.
His little brother, Kota, is also a bull and one day he'll be sold off too. It hurts Izuku's heart to think about and he hopes there is some way for his brother to stay, but his hopes are low.
He's in the field relaxing with his mother, Kota drinking from her breast, when he feels too hot and itchy. Inko knows immediately what's going on and, with Kota's help, gets the other heifer into his stall in their barn.
Izuku is a whining, crying mess by the time their owner Aizawa comes to check on him. After a quick evaluation that leaves Izuku feeling VERY confused about the older man, he's left alone in his stall again.
His mother comes in later after she put her youngest to bed to check on him. Kota is young but he's still a bull and would respond to Izuku's heat regardless of relation if he got too close.
Inko shifts her son's head onto her lap and pet his head, she cooed at him and tried to soothe him. "Izuku, sweetie, this is what I was telling you about. You'll be moved to the breeding barn for a bit tomorrow. Try not to stress out about it, Aizawa won't let the bull hurt you."
It doesn't do much to comfort the small heifer, but he knows his mom is trying. He's scared and unsure about this whole 'mating' business. What if the bull doesn't like him, or won't mate with him? What happens then?
Eventually he falls asleep on his mother's lap and when he wakes the next morning its to Aizawa carefully tapping his shoulder. The man gently gets him standing and helps walk him to the breeding barn, all while petting his hair.
The barn is empty except for the pile of plush pillows and blankets that Izuku is laid down on. He lets out a small moo of contentment as he snuggles into them. Aizawa pats him and assures him that he'll be back soon.
Izuku wants to be nervous but he knows that the bull will make him feel better, at least that's what he's been told. After what feels like forever to the heifer the door opens and Aizawa steps in holding the lead to what is probably the biggest bull Izuku had ever seen.
Tall, broad, muscular, and large in every way imaginable, the bull stomps into the barn and wuffs at the air. He's blonde with bright red eyes that take in everything, and once they land on tiny little Izuku they never leave.
Izuku flicks his tail nervously, this bull is much larger than he thought, how would he mate with him? Would he even fit? And his horns! Why were they so intimidating? Izuku pulls the pillow he's laying on closer to his face as he looks the blonde bull up and down.
Aizawa has to pull the stud back in order to unlatch the lead from his collar, the bull's ears twitching in irritation as he huffs impatiently. "Be gentle with him Katsuki, he's new to this." The man's words seem to excite the bull further though.
Katsuki stalked forward slowly as Aizawa left, the owner would be able to watch them discreetly from another room. The bull had bred many heifers before but none of them had been so small and cute.
None had been virgins either, he'd have to be very careful and coax the tiny thing into it. The blonde stood above the green haired heifer and took in every detail. Every freckle, his big green eyes, his nervously twitching tail.
He bet under that tail was a cute pink pussy and cocklet waiting for his attention, but he'd have to calm Izuku down first. Katsuki carefully knelt beside his breeding partner and reached his hand out slowly.
Izuku eyed the bull before taking his hand, he was so warm and smelt so amazing. Musky and heavy in the best ways, it made Izuku hum happily. Katsuki smirked as he moved to pet and soothe the other, he was the best stud around and he was going to prove it to the heifer.
Once the small heifer had been calmed and relaxed enough Katsuki carefully rolled him onto his back. He ran his hands over Izuku's small tits imagining them full of milk because of him. He moved them down to his currently flat tummy. Katsuki vowed to change that very soon.
The bull finally took Izuku's cocklet into one large hand and circled the head gently. Izuku arched into the touch and moaned, he wanted more so badly.
While Izuku was focused on his cocklet being touched he didn't notice Katsuki using his other hand to reach for his clit. A large finger pressed on it lightly and Izuku's little hooves dug into the bedding in shock.
"M-mooore!" He reached up to hold onto something, anything really, to ground himself. Katsuki was happy to oblige the demand and began to assault his clit and cocklet at the same time. This had the heifer shrieking and moaning in pleasure he wasn't used to.
A smug smirk stayed plastered on Katsuki's face as he quickly pulled an orgasm from Izuku's body. He teased the other through his release before moving the hand on his clit further down to his leaking hole.
He sunk a single finger into the slick pussy and groaned, Izuku was so warm and tight he couldn't wait much longer to fuck him. Izuku's body clenched down on that single finger tryin to suck it in more, it wasn't long at all before he was being fucked on four of Katsuki's fingers
By then the bull had had enough and was ready to mount the heifer, so he quickly pulled his fingers out and spread thick, soft thighs. He wanted to watch Izuku's face as he took a cock for the first time.
Despite the prep Katsuki made sure to be careful, he was after a large bull and he didn't want to be taken from this cute heifer for being too rough with him. He was slow as he pushed in, the head struggling to pop into the small hole for a small second.
Once he got past the slight resistance he slid into the warm velvety heat of Izuku's virgin pussy. The two of them groaned in unison, and Katsuki made sure to sit still for a bit so that he didn't hurt Izuku.
When he looked to heifer over Izuku was rubbing at the slight bulge in his abdomen in amazement. Katsuki couldn't help the slight stuttering thrust at the sight, and the smaller of the two wrapped his legs around him in response.
"So f-full~" Izuku circled his hips a bit trying to get some stimulation and Katsuki growled. The heifer thought he'd upset the bull, but decided he very much didn't when the man pulled his hips back only to slam back in.
Katsuki held onto one thigh and placed his other hand beside Izuku's head as he rammed his cock into the slick pussy. He was supposed to be gentle but from the look of bliss on Izuku's face, he was pretty sure the heifer loved it.
The bull set a harsh pace, the sound of skin slapping echoing into the room mixing with Katsuki's grunts and Izuku's wails as he was fucked within an inch of his life. The small heifer's eyes rolled back into his head as he came again with a cry.
Katsuki leaned down completely to mutter filthy into his partner's ear. "Gonna breed this pussy full. You look so good stuffed with my cock, maybe I should keep you for myself. Not let any other bulls near you." Izuku whined and wrapped his arms around Katsuki's neck.
Technically they weren't supposed to bond, but Aizawa never told them not to so Izuku was 100% okay with letting this bull mate him permanently. He even tilted his head to the side to bare his neck and began to beg. Well as much as he could while still being fucked senseless.
"Fuck!" Katsuki moved his mouth over Izuku's neck cautiously, "want me to claim you? Keep your stuffed with my cum all the time?" Izuku wailed and begged the bull to do it. "Gonna keep you fat with calves, baby, just mine nobody else's." The bull growled out possessively.
Katsuki felt his knot tugging on the rim of Izuku's pussy and grabbed his legs to push them into a mating press. He dug his hooves into the pillows and fucked into Izuku desperately.
The two cattle drew closer and closer to release, and once Katsuki's knot locked into Izuku's pussy he latched onto the heifer's neck as he emptied everything he had into him. Izuku milked his knot of every last drop as he came for the third time, and Katsuki's eyes rolled back
from how hard his orgasm was.

He'd never cum so hard in his life, not with previous partners, and he was sure as hell keeping Izuku. Katsuki rotated his hips a bit to make his orgasm last to make sure he bred the heifer good and by the time his knot went down Izuku was asleep.
Katsuki moved them both onto their sides and cuddled the small heifer close, he had his back to the door to protect his mate. He growled at Aizawa when the man brought food and water for the pair, but he only snorted at the bull.
Katsuki huffed once he'd left, at least the man would be useful while he was breeding his mate full.

Izuku is relaxing in the field with his mother, Kota fully weaned off his mother's milk, while his large mate stands guard over them and proudly eyes him. Izuku is heavily pregnant with triplets, tits fat and leaking milk constantly.
You would think now that Izuku is pregnant Katsuki wouldn't back off a bit, but he still very much loves to pump his tiny mate full of his cum and suckle from his tits. Izuku isn't bothered by that in the slightest.
Everything is perfect, Aizawa had even mentioned how since Katsuki was such a good stud that he planned to buy his little sister Eri for Kota. So everything was absolutely perfect for Izuku and his growing family.
And he couldn't wait for his young to be born so Katsuki could fuck him full again.
