The low hum of the machinery in the wooden barn was being smothered by the much louder *tsss - chss* sounds of the hydraulic pumps, and the moans of pleasure coming from the cows in the barn.
It was milking time.
Jenny walked along the central aisle of her barn to inspect her cows, and was pleased with what she saw. Jenny was a cow-farmer and she looked the part. She had the look of the 'girl-next-door' about her, with a cute button nose and freckles across her cheeks, on a face that was encircled by her long curly locks of deep red hair.
Her body was average for a woman of 26; slender, but clearly strong from her laborious farmwork, with small breasts and a strong behind. When Jenny looked at her cows, she was often reminded how glad she was to have a small chest so it didn't get in the way of her work. She was dressed in a red flannel shirt that was tied up under her bust, and a pair of denim short shorts, as well as some wellington boots and a baseball cap.
The barn was laid out as a long open space with a large pumping machine at one end and the door at the other, with 8 stalls like that of a horse's on either side. In the stalls were some padded sections for comfortable seating, so the cows could relax as their mammary glands got drained by the groaning machines that surrounded them.
The tubes connected to their teats all ran up to be strung along the ceiling, and they went off into the second barn next door that had the containment tanks for all the milk the cows produced, and they produced a lot; Jenny originally had the tanks at the end of the barn next to the machine that ran the milking pumps. But now, with more cows with bigger mammaries, she needed to have the tanks in their own barn.
The cows that Jenny farmed, however, weren't the kind of cows you'd find grazing in a field, or being slaughtered for steaks. In fact, they weren't actually cows at all. They were human women that carried a rare genetic trait.

A long, long time ago it was found that some women had a randomly occurring trait in their DNA which meant they could lactate even when they weren't pregnant, and there was a connection between how large their breasts were and the volume of milk produced. It was also found that the milk these women produced was absolutely delicious; it tasted amazing in teas and coffees, and worked much better than dairy milk for cooking and cheese/yoghurt making.
Before long a market arose for this kind of milk, and demand required supply. Women with the trait would be hired to work on farms as 'hu-cows', where they would be milked. It was a good gig; they were given a place to live on the farm, plenty of free time outside of being milked, and good pay. Not to mention, the milking process was very sensual, often causing the women to orgasm as they were drained.
Back then though, the women looked like normal women. They would be tall, short, fat, thin. Some would have bigger breasts that created more milk, some would be smaller with less milk, but given how rare the trait was the farms that employed them would take what they could get. However that changed when people realised what happened when women with this particular genetic trait had children with men that had the same trait.
These men didn't lactate, obviously, but instead were very productive in the semen department. They had prostates that were larger than usual, and their genitals would often be larger than average too. Again, like the women and their milk, the larger a man's penis and testicles were would mean he would produce more semen, that was thicker and more virile. It didn't take long before it was found that if a man like that impregnated a woman with the trait, their child would grow up and be even bigger than their parents, and the bigger the parents, the bigger the child.
Soon, milk farms would pay enticing extra bonuses to their hu-cows to get knocked up by a man with the trait, as long as if their child was female they would have the sole employment rights to them. This was a long term investment for the farms as the hu-cows would only be eligible for work when they turned 18. Many women who were already looking to have kids took up the offer, enticed by the financial bonus and the promise of employment for their child, and the process would more often than not repeat with their kids when they reached 18 and got employed as another hu-cow. It also had a secondary function for the farms, as pregnant hu-cows produced even more milk, and the extra milk their mammaries made was even sweeter than their normal produce.
Eventually there were whole dynasties of hu-cows that would stay with a farm, each generation having bigger breasts than the last. However, as is to be expected, half of the time the women would have a boy instead of a girl, and so a new industry popped up that would employ those boys when they turned 18 to breed with lots of hu-cows to make even bigger hu-cows, and as the men came to be known, hu-studs.
This system of hu-cows and hu-studs snowballed as more farms wanted in on the action, and those that were doing it wanted even bigger breasts on their hu-cows for more milk per hu-cow, while still only paying one salary. The women got bigger and bigger breasts, while the men got bigger and bigger penises and testicles from generation to generation. Most importantly, the bigger a man's penis was, the larger the effect for their offspring, and the same went for women's breasts, so everyone wanted the biggest hu-cows and hu-studs they could get for the best breeding results.
Fortunately as the sizes began to reach an inhuman scale, people realised that the hu-cows, along with their now huge boobs, were 'stretchy' enough to be able to actually still take a hu-stud's penis in their vagina, seemingly regardless of the sheer sizes they could reach.
