When lactating, Charlotte goes on a camping trip with the man of the house, she's blissfully unaware of the twist the evening would take. They are not alone in the depths of the forest, and if they are to escape, the pair must go down a taboo path of forbidden temptation, while giving a mythological beast the milky protein he needs.

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.

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.

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.

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.
