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.

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.

Tough investigative reporter Lucy had her life completely overturned when she broke into the Science Institute and discovered Dr. Felton's milking operation. To keep her quiet he converted her into one of his human cows. Sold to an American farm, she was content to eat grass and be regularly milked and humped until a tornado upsets her daily routine.

Marie was a student and, like most students, she had no money and didn't know how she was going to survive another term. Browsing through the student magazine, she saw an advert offering thousands of pounds for suitable young women to submit to medical trials. Little did she know that the ad had been placed by an uber-rich and super-intelligent scientist, Dr. Andrew Felton, who had dedicated his life to making his ultimate perversion come true. He was creating human dairy cows.

When 19-year-old Jessie is offered a job on a milk ranch out in the middle of nowhere, it seems too good to be true. Meeting the gang of tough mountain men who run the dairy farm makes it even better. And when she finds out just what goes on in the cow barn and what they really want from her....

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.

Lauren, the horsey-looking English girl, was now the newest recruit in a Texan pony ranch. Restrained and transformed in a tight-fitting pony suit, she was tethered to a rail in her stall and used relentlessly throughout the night. Now her first proper day of training begins and she is determined not to disappoint her Master.
