It had been a tough five years since I left university. Back in my native Manchester and staying at my mom's, I was used to rejection. With no proper job, no boyfriend, and few friends, I had no idea what was wrong with me. I mean, I liked what I saw in the mirror, and I had a piece of paper that said I was really clever! Then, out of the blue, an opportunity came up which was to change my life. A group of wealthy men were developing a drug to make women lactate on demand. That’s worth a lot of money on the markets.

Since making his fortune discovering a way to triple the milk yield in dairy cows, Dr. Gary Felton had used his wealth to develop his interest in lactating women. His development of the drug to work in human women had led to the establishment of the science institute for just that purpose. Along with Sally, his partner in business and love, they took great care in selecting attractive young women to exchange their former lives for one that revolved around their breasts.

The milking experiment is a success, and Dr. Gary Felton is ready to sell his stable of nubile young human cows to the highest bidder. Marie and the rest of the herd face the world with wide bovine eyes and inprobably large breasts that need to be milked regularly.

Twenty-one-year old Carrie was on a gap year from university and had nailed a great job on a dairy farm. On her first day she was told under no circumstances was she to go into the quarantine shed. On her second day, she found she needed to! What she found inside was a deep shock to the innocent young woman - human females being milked! Within minutes she was on the way to joining them, strapped to an infernal machine.

Investigative reporter Lucy bit off more than she could chew when she broke into the Science Institute and discovered Dr. Felton's lucrative business; converting pretty young women into human milking cows. Captured by the security guard, she received a large dose of Formula X herself and before long her life became unimportant as long as she was milked regularly and sexually satisfied.

Diane was a young surrogate mother who had just given up her baby. She was bored and depressed and need to earn some money. Her days were now spent in searching the job ads and continuing to fill her fridge with breast milk - she liked to express it and couldn't bring herself to stop. Finding an ad for young surrogate mothers wanting for paid research seemed to be a dream come true. Her interview with Professor Ed Dorking was not quite what she expected though.

Investigative reporter and Hucow escapee Lucy was back, but on her own terms. Tempted back into a life of milking and highly charged sex, she ensured the deal she cut allowed her complete autonomy and a chance to make a difference as a Hucow welfare worker. Visiting all of the girls that had been converted, trained and sold by Dr. Felton was a great way to ensure they were being well looked after, but it also exposed her to a risk she hadn't considered.

Sarah, the stunning young health and safety inspector, had adapted to her life as a human cow surprisingly well. Joel the dairy farmer now looked after all aspects of her former life for her, managing her finances, emails, and text messages. And then, all of a sudden, a desperate email from her younger sister leads to the sluttish and over-confident Melissa turning to him for help out of desperation. Joel was only too willing to welcome her into his herd.

Joel was very happy with his human dairy farm. His girls were healthy, content and productive and his milking machine was surpassing all expectations. Now fully automatic, it had the capability of turning any woman into a horny, submissive dairy cow ripe for milking and shagging. Things couldn't be better until he got notification of a snap health and safety inspection.

Diane, the surrogate mother, was quickly adapting to her new life in the institute. Milked several times a day, her pussy was also available to the staff whenever they wanted it, which was a good thing, as her libido was sky high. Once into her daily routine, she was ready to meet the professor's clients.

It was supposed to be a medical marvel. Instead, it triggered the apocalypse. Half of humanity mutated into mindless zombies. Half the survivors mutated into the inhumans: various new species of people with new appearances and abilities. Some grew scales, some grew fur, some could fly, some could survive only underwater. Decades passed, and from the ashes of the old world, a new patchwork civilization rose. Humans and inhumans lived in tentative peace, and the zombies turned out to be not much of a threat once a few generations of survivors had come and gone.

Dr. Gary Felton was a very successful and wealthy man. He made his first fortune by developing an innovative formula for boosting the milk yield in dairy cattle, then he was able to feed his own fetish by developing a version for human women, producing milk without pregnancy and sending libido skywards, whilst the girls' IQ fell like a stone. He built a business for procuring, treating and then selling beautiful young girls as compliant human cows.

Serving on the hucow farm is hard for any eighteen-year-old girl. Growing ever bigger and more productive, being handled by strangers with her massive dripping udders emptied by eager hands and mouths, or attached to machines for fierce suction pumping, while her juicy, ripe body is available to all who want to use them is bad enough. But it's even worse for the once-aristocratic Daphne, as the men of the farm take a cruel revenge on her.

When Valerie and her husband Jeff set up camp in the clearing of a dense jungle, little do they know whose lair they are trespassing on. Jeff is about to become the victim of some extremely milky cuckolding, as the beast takes a fancy to his lactating wife.

Maria gets transformed into a hucow and is claimed by a rancher called Ulf who turns her into his personal cow and sex slave.
