Work Text:
Life on the farm was simple and the work was hard, and Keith wouldn’t want it any other way. There had only ever been one possible future career for him: join his father, Tex, on their farm. Both being betas, they were left unaffected by heats or ruts, either from other people or animals. He had always helped around the farm, but once he graduated high school, it became his fulltime endeavour.
His mornings started early, joined by his loyal dog Kosmos, going out to feed the animals and let them out to the pasture. The rest of the day would be filled with chores such as taking care of the different crops and performing various manual labour (there was always a broken fence somewhere). This time of year, it was the cattle breeding season. The cows were getting restless and sniffing and mounting each other, showing early signs of going into heat.
There were a couple of options for insemination. Tex has bought some sperm for artificial insemination from some reputable breeders that they could use on some selected cows. They had their own male alpha bull who they would introduce to the cows and let nature run its course. However, he was getting up there in age and Tex worried about overburdening him. Consequently, he had acquired a new and younger male alpha bull. He was a beautiful specimen with black and white hair. Keith found himself captivated by the bull, called Shiro, who also seemed to be rather affectionate with Keith as well. When he was out working, the new bull would often stand at the edge of the pasture and observe him. When Keith was in the pasture, Shiro would stand next to him and occasionally snuggle up to him. Keith couldn’t deny that it was endearing.
When the cows went into heat, Shiro was introduced to them, and he would spend 6 nights with them. While they let Shiro take care of things the natural way, the selected omegas for the artificial insemination were brought into the breeding barn with the special machines for semen extraction and insemination. Keith gently guided a young heifer down unto the breeding bench, a construction where the omega would lie down in their stomach on a padded surface. Their arms and legs would be strapped down for both their safety, and then the bench would be angled slightly so their behind would be elevated.
He walked up behind her and gently patting her on the rump and talked to her in a soothing voice, helping her relax. He put on the gloves and cleaned and lubricated her genitals and anus. He grabbed the loaded breeding gun, spread her vulva lips, and gently inserted the gun at a 30-degree angle with his right hand. His left hand gently massaged and then entered her anus. Through the anal cavity, he helped guide the gun through the cervix and into the uterine body where he slowly deposited the semen. He then gently removed the gun and inspected it for any abnormal discharge, of which there was none. He patted her on her back and released her from the straps. He helped her up and guided her out to the pasture again, where she was free to roam and relax, and went to get the next heifer.
At the end of the day, the animals were returned to their barns and fed their dinner. When everyone was locked up safely, Tex and Keith could return home, get cleaned off and get started on their own dinner. They slumped down on the couch to watch some television before heading to bed. The following days went by similarly. After six days, the alphas were separated from the omegas and returned to their own pasture. The cows were then divided into those two groups, based on who went back into heat, and thus were not pregnant, and those who had successfully been impregnated and thus didn’t go into heat again. The ones who went back into heat were then returned to their assigned alpha. As is normal, a few of the omegas of their old alpha bull went back into heat, but, abnormally, so did every single one of Shiro’s omegas.
Shiro was to spend another six days with the omega cows, but this time, Keith went over to observe the group every opportunity he had in between chores. What he observed was strange. Shiro would hang out with the omegas, but any time any of them presented themselves to him to try to get him to mount them, he would turn them down. His group consisted of a good selection of different omegas, both male, female, and non-binary, as well as different ethnicity and ages. Since they could rule out Shiro turning the omegas down due to having a strong preference for a certain type, they had to investigate what other possible reasons could result in his refusal.
“Dad, I don’t know if Shiro knows he’s supposed to mate with them,” Keith later told Tex. “He doesn’t seem interested in any of the omegas at all.”
“He is in rut, so him resisting it for some reason would be baffling. An alpha’s instinct should be all they need to figure out what to do. But maybe he needs to see an example,” Tex said.
They guided Shiro to where the older bull was with his omegas to let him observe. Two alphas in rut could get violent, so Keith and Tex kept close, ready to intervene. The older alpha seemed agitated at first, but when Shiro yet again showed no interest in any of the omegas, the bull calmed down and went about his business. After a while, they brough Shiro back to his omegas, who seemed excited to have him back, but, despite his rut, he made no attempt to approach any of them. Keith couldn’t wrap his head around it. They knew from tests that Shiro wasn’t infertile. Had the omegas refused him? Keith couldn’t believe that. Shiro was the most handsome alpha Keith had ever laid eyes on. Even Keith caught himself admiring the alpha when he walked by the pasture. And when he saw Shiro interacting with the omegas, he was always gentle and caring. There was no way the omegas were rejecting him.
“We’ll have to extract his semen and just insert it into the omegas at this rate,” Tex concluded.
“I want to try something first. I’ll try to guide him to an omega, see if that makes his instincts kick in,” Keith said. He still preferred when alphas and omegas just mated naturally.
The next day, Keith took Shiro and one of the omegas to the breeding barn. He strapped the omega down to the bench and angled her behind up. She looked up at him expectantly.
“Let’s see if we can get your alpha to give you want you want like this,” Keith said while patting her on the head.
He guided Shiro behind her. Shiro stared at him. Keith put on gloves and took Shiro’s dick out. Shiro nuzzled his face into Keith’s neck. Keith brought the tip up to the omega’s entrance. The omega pushed her behind further up, trying to get her alpha in her. While Shiro had gotten hard and his cheeks were getting flushed, a sure sign of his rut, he was resisting mounting the more than willing omega in front of him. In fact, he was pushing himself harder and harder unto Keith.
“Okay, calm down, big guy,” Keith said as he tried to direct Shiro towards the omega to no avail. “I’m trying to help you, but I don’t know what your problem is. Is it because she’s a female omega? Do you prefer male omegas? Hold on, I’ll fetch one.”
He released the female omega, but before he could leave to find a male one, Shiro grabbed Keith and pushed him down unto the breeding bench. Keith was stunned for a moment. He felt Shiro panting into his ear. He managed to turn his head around to meet Shiro’s pleading eyes. He was gorgeous. Shiro leaned in and kissed him, and Keith kissed him back. Shiro licked at his lips, Keith opened his mouth and let him in. Shiro eventually pulled back and kissed his neck, sucking on the skin. He kissed down Keith’s spine to his lower back.
“Oh... I’m not... I’m not an omega, I’m a beta, though...”
Keith felt the Shiro’s hands run along his back and down to his waist. Shiro managed to unbuckled Keith’s pants and started tugging at, trying to pull them down. And Keith... didn’t fight it. He thought of his position on the bench, his face down and his behind raised up, while a strong and handsome alpha was caressing him. He found it a humiliating position, but it was also so titillating. Was this how all the omegas felt? He raised his hips further, allowing Shiro to pull his pants and underwear down. Shiro went down to his knees, took a few sniffs, which filled Keith with even more embarrassment, before he started kissing and finally licking between Keith’s legs.
A warm and wet tongue slowly circled Keith’s rim. Hands were running up and down his thighs. A fire was building up in his stomach. The tongue entered him, and Keith gripped the bench tighter. He felt his muscles relax as Shiro worked him open. Keith reached back to pet him on the head.
“That’s a good boy,” Keith whispered.
Shiro perked up at the compliment and devoured Keith’s ass with even more devotion. Keith started to believe he could cum just from Shiro’s tongue. He was ecstatic that Shiro wanted him. He felt as if he was going through some kind of pseudo-heat. He grabbed Shiro’s hair and gently pulled him up.
“Enough. Fuck me already, you big, beautiful, stubborn creature.”
He needn’t ask twice. Shiro crawled on top of him, enveloping him like blanket. He lined himself up with Keith’s hole.
“Do it,” Keith moaned.
Slowly, Shiro started to enter him. First, the head. The stretch was heavenly but not without pain. He was a big boy in many ways. Shiro pushed a bit deeper, then gently started moving in and out, getting deeper with each thrust. Finally, Keith felt the knot pushing against his rim.
“That’s the downside of me being a beta, that thing is never going to fit in me,” Keith panted. He had all the Shiro he could possibly take in him now.
Shiro’s mind had been a mystery for Keith, but meeting his eyes, Keith understood that Shiro had taken what he said as a challenge.
“You are NOT going to knot me, you crazy bastard!”
Shiro kept thrusting with more determination. Keith was clutching the bench as he was stretched further and further. He was drooling. He was moaning. He was in heaven. Shiro leaned over Keith and peppered Keith’s neck with kisses. What a wonderful alpha he was.
Shiro reached down to stroke Keith’s dick, and that was the last push he needed to be sent over the edge. His muscles tensed as he came with the most intense orgasm he had ever experienced. Keith felt himself turn into a puddle of bliss. Shiro, however, was relentless and barely gave Keith time to recover. He kept pushing with more fervour and resolve, until finally, his knot popped past Keith’s rim and he sank himself all the way into Keith’s body. With a few short thrusts, he came and emptied himself deep into Keith. Keith moaned as he was filled beyond what he could ever have imagined possible.
Shiro finally came to a rest and gently nibbled on Keith’s ear. He wrapped his arms around Keith’s waist and pulled him as close as he could.
“Is this what you wanted, you silly boy?” Keith said, out of breath.
Shiro made a low sound, which Keith interpreted as a confirmation. They lay down together, waiting for Shiro’s knot to go down. Keith felt Shiro and his cum inside of him. Maybe he could still salvage it and use it on the omegas.
Keith reached his arm around to gently pat Shiro on the head. “Is this how I’m going to have to extract semen from you from now on? Is it going to be like this every time?”
Shiro murmured contently in agreement.
