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.

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.

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.

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.

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.
