Buttercup was the most adorable little hucow in all the land. She had curly red hair on her head and curly red fur between her legs, with a beautiful smile and big, deep blue eyes, and the cutest moo. Her hands were encased in artificial hooves, and her calves were permanently bound to her thighs, with artificial hooves below the heavy-duty kneepads on her knees, and her little pink toes wiggling above her ass. (Her leg bindings were absolutely necessary; she was so top-heavy that if she were ever to attempt to stand on two feet, she would fall over and injure herself.)
She was always completely naked otherwise, and thought nothing of it, since cows naturally did not wear clothing. Her most prominent feature, of course, was her beachball-sized udders, which looked even more magnificent on her small frame.
People often wondered how she could move, even on all fours, but from long practice, she managed to crawl along quite well, with her massive mammaries swaying ponderously below her torso, and her dark red, swollen nipples in constant danger of brushing the ground. She might not move rapidly, but once she was in motion, Buttercup was a rare work of art, heating the loins of everyone who gazed upon her, and she was in excellent shape from constantly carrying the weight of her own chest. Despite her heavy load, Buttercup moved with surprising grace.
It was a struggle even for the muscular Buttercup to move, however, when she had gone unmilked for too long and her straining udders were distended with the weight of her milk, with each udder accumulating as much as a gallon. Fortunately, Buttercup's owners were kind and loving and milked her several times a day, in addition to pulling milk from her udders directly into their morning cereal and coffee, as she mooed in delight.
Sometimes they would use a milking machine if they were in a hurry, but Buttercup much preferred it when her owners milked her by hand. She loved to feel the rhythm of human fingers tugging on each teat alternately, and she loved the sound of her milk spray hitting the bucket. She was so, so lucky that her breeders had sold her to this family instead of one of those soulless automated dairies.
Buttercup was also the vainest little hucow in all the land, and was enormously proud of her milk production. "Five people is nothing! My udders could feed an army! I am hucow -- hear me moo!", she would think to herself. And in fact, Buttercup usually came home from the county fair with blue ribbons, which made her even more vain. Her owners could not even keep up with drinking all her milk, and either used the excess to make cheese, or sold it to local shops. It was no wonder that Buttercup strutted with pride on her little hooves.
Buttercup's owners were also her lovers. Hucows, in addition to industrial-scale lactation, had been genetically engineered for perfect docility and submissiveness, and were incapable of aggression; but they were also genetically engineered to imprint upon the scent of an owner's genitals, with a superbovine sense of smell that let them infallibly recognize individual women just by the smell of their privates. The intent had been to hardwire the bond between hucow and owner; and Buttercup was bonded to her owners with a deep and passionate love as soon as she tasted them.
At least one of Buttercup's owners, and usually more, were always available to let Buttercup lick them out after her milking, and she strove to communicate her love and loyalty with every stroke of her clever tongue into their delicious pussies. The taste was intoxicating to her, even more so than her owners' aphrodesiac scent. Even better was when they used Buttercup's cunt, gently stroking her red pubic fur and stimulating her to orgasm with fingers or one of Buttercup's sex toys. Buttercup orgasmed easily and frequently, mooing loudly in ecstasy and melting with love for the wonderful family that owned her. And of course she was spoiled with lots and lots of petting and kisses. It was a wonderful life!
(Buttercup's vaginal recognition was so highly developed that she had won tracking competitions at the county fair. Blindfolded, she had made her way unerringly through a crowd of women to lift her head and kiss her owner's (clothed, unfortunately) genitals. Hucows' sense of smell was so acute that specially trained hucows had begun to replace bloodhounds in search and rescue operations, at least when the missing person was a woman. All you had to do was rub a pair of used panties on the hucow's face, and she was good to go.
(There were tradeoffs, of course: a hucow was slower on the ground than a dog, but rescued women tended to be dehydrated and in desperate need of sustenance, and a hucow did a much better job of providing it. Of course, the rescued women were sometimes embarrassed when told what had led the trackers to them...
(There was even a reality show, which Buttercup had watched with her owners, about a motherly Black tracker hucow named Molly. Buttercup had loved the scene at the end where a gaunt woman knelt on the ground next to a triumphantly smiling Molly, hugging Molly's large soft, warm body tightly to her with one arm, while using the other to hoist one of Molly's gigantic udders to her lips, sucking thirstily. That looked like fun! Buttercup wondered whether Molly would get to lick out the woman, or whether the maternal hucow's reward would come from the male handler standing behind her holding her extensible leash. They never showed that part on TV, for some reason, but that was what Buttercup really wanted to see!)
There was a distant cloud hovering over the otherwise sunny sky of Buttercup's placid life, however. She lived in constant trepidation about the bane of all hucows - hucow rustlers! She occasionally overheard her owners discussing the news, and once or twice they were shaking their heads over how rustlers had stolen several hucows nearby. This terrified poor Buttercup. How could people be so cruel? She loved her family and her home so much, and did not ever want to be taken away from them. She didn't think she could survive without them.
Obviously Buttercup was a prize hucow and immensely valuable, she thought, glancing down at her immense chest and swollen nipples with no false modesty, so she was bound to be a prime target for those villains. She tried to reassure herself, though, that her owners would always keep her safe.
