It was hard for Bryan to keep track of time as a bull. So much of his time was spent doing nothing but eating, drinking, regurgitating, chewing, sleeping, relieving himself, and being taken occasionally for semen collection, that every day was pretty much the same. Eventually, though, he realized that it had been a long time since he had even thought about most of it as weird or disgusting, the way he had at first. He was finally in the habit of being a bull, and even though he would have changed back instantly if he had the chance, he was finally getting used to just going through the motions like the mindless piece of livestock everyone assumed he was.
"Even if I could change back, how long would it take me to get used to living as a human again?" he asked himself one day. Would he have to retrain himself on how and when to use a toilet? Would he think as quickly as he used to? Would he be able to do his job right away, or would he fumble and zone out since he was used to just flicking his tail and chewing his cud? Would he go back to his original sex life as a 20-year old, or would every orgasm remind him of getting used like a farm animal? One thing Bryan was sure of was that he wouldn't take his humanity for granted anymore, if he ever got it back. He would take more rigorous classes and travel to more exotic places. He would aim for something in life beyond just working at a fast food restaurant.
Another thing Bryan was sure of was that it would take time to convince his human self that he was truly no longer a bull, if he ever turned back into his human self after all. Even Bryan's dreams were bovine now. When he slept, he saw his human friends less often and almost never imagined himself as a man. Usually, he dreamed about grazing or semen collection. Occasionally, he dreamed about fighting another bull, not that he'd ever done yet. More disturbingly, he sometimes even dreamed about mating with a cow. On some level, he wanted to know what it was like to use his massive equipment the way it was meant to be used, inside a cavernous female opening. The cow sex dreams usually started as human sex dreams, until the human turned into a cow and turned around for him to mount her. He usually tried forget about those dreams and remind himself that it was never going to happen: the humans had given up and getting him to do that and were totally committed to artificial insemination. It was the last bit of humanity he was holding onto, that he would never demean himself to the point of fucking a cow.
One day, they brought Bryan into the place where he met the vet as usual, and Bryan became erect at the thought of their probe. Instead, though, the vet brought out a different piece of equipment, one that had an elastic band. The vet confirmed one last time that Bryan's owners were ready to proceed with the castration. Bryan's heart sank when he realized that his sex life was over for good. They had enough frozen sperm to keep impregnating cattle long after he was dead, so he was just future beef to them now. He tried to tell himself it was for the best, and that maybe he would stop lusting after cows and going crazy in his stall whenever he smelled them in heat. Somehow it wasn't much comfort when the band closed in on his huge scrotum, crushing all of the tubes his testicles needed for their survive. He bellowed in pain and had to live with that pain when they send him away with the band still squeezing his ballsack.
The pain gradually tapered off, and so did all of the other feelings from his balls. He stopped getting horny and started getting lethargic and lost his appetite for a while. Eventually, he recovered from that but still felt a certain tranquility that was refreshing after being so impulsive and unpredictable the entire time he was a bull. He dreamed more about grazing and less about sexual encounters. He sometimes thought back to his semen collections and cringed that he had actually somewhat enjoyed taking probes in his ass and giving people fluids out of his pizzle. Eventually he just found it hilarious and could even laugh at himself for constantly thinking about sex with women while he was a man. It felt like such a silly waste of time, and he could barely even remember what orgasms felt like to even justify wanting them so bad!
Finally, one day, while Bryan was grazing thoughtlessly, swishing away flies with his tail, something plopped onto the ground beneath him, and he felt less weight on his crotch. Looking around, he realized it was his balls, they were finally dead and gone. At least in some amount, the finality got to him. He stared at them for a moment and wondered if he'd ever miss feeling like man (or at least a bull). His ability to create new life, even calfs, was gone. The orgasms he used to want and now barely remembered were just going to become an even more distant memory with time. Then Bryan zoned out again, stuck his nose back to the ground, and got himself another mouthful of grass to enjoy. He was starting to put on a lot of weight now, and he knew all too well why his owners wanted him to.
Bryan lifted his tail and let go another bladderful of liquid waste through his long male organ, the only thing he would be using it for until it was time for him to be slaughtered.
