A woman ruled over a certain small country as its lord. This woman was a vampire who had been living for hundreds of years. She kept her eternal youth by drinking and bathing in the body fluids of young girls. At first, she used their blood, but, because of that, she had to kill many of them. As time wore on, it became difficult to maintain a supply of humans, so she decided to take another approach. That approach was to remodel the girls as cattle and raise them as "human livestock." By using her magical powers to turn the girls into hermaphrodites and increase the amount of body fluids they secrete, she converted the girls into livestock more valuable than cows or goats. It turned out that human semen was just as nourishing as blood. Moreover, the subject did not need to be killed for it, and it could be harvested any number of times after brief intervals. For harvesting the semen, she made use of a modified milk machine originally used for cows. Installed on the girls' penises, the intense stimulation and suction that the machine delivered proved so effective that tens to hundreds of liters of semen were milked out per day.
This "farm" steadily grew in scale. The girls were made to copulate and bear young, and their young were, in turn, raised as cattle. The large quantities of milk wrung from the girls that gave birth were used as food for the other girls. Those that grew weak with age were slaughtered and had every body part fully utilized - meat and organs for food, bone for fertilizer, fat for lighting, hair for carpet, and so on - until no trace of them remained. Outstanding individuals were trained to take care of the other girls and also, apparently, to work as servants for the lord.
Many decades later, this vampire was overthrown by a lone hunter, but, by then, about 150 girls were being kept as livestock and over 10,000 girls had been killed.
