Jeff knew what he had to do. A fetish of his had been just a dream before now. But with the Chronivac's power, he could finally make it a reality.
Jeff planned to go global with his scale, affecting every last adult human on earth. He planned to reinvent how they consume.
To begin with, Jeff fantasized about a world where there were a few different kinds of humans. 3 to be exact. There are the producers, the feeders, and the consumers. And everyone will become one of them upon reaching adulthood. With an extremely low possibility of gaining the characteristics of more than one type.
The consumers are the largest portion, being exactly half of the entire population. While the other two each hold a quarter share.
Starting with the producers, these would be an entirely female population which would all develope 4 large breasts and an udder between their legs. Their bodies are optimized to create as much milk as possible, and do not require any kind of external source of nurishment. Not unlike how a plant can produce its own food, their bodies can do the same, though far more efficiently to the point that all excess is turned into their milk. They tend to enjoy a much more laid back lifestyle, staying in one place, not moving homes. They rarely will want to leave their town or city's area unless absolutely necessary. They love to socialize with other producers and feeders, while letting the consumers take care of all their needs for them. And while they live a pretty spoiled lifestyle, they are not able to take advantage of it due to their low levels of ambition.
Feeders live hand and hand with producers, and can only consume the milk a producer makes. Their bodies will tale any excess milk they consume and turn it into a special kind of cum. The cum is highly nutritious for consumers and is their exclusive source of food. Feeders will typically spend their lives servicing the other two groups. Either by milking the producers or by feeding the consumers. It is very common for a feeder and a producer to live together too. Feeders are all futanari, and store their cum inside their balls. This causes them to swell considerably large, often times restricting the movement capability of the feeder until they have been emptied enough to move again. This can be done either by feeding or through orgasming. There is a difference between the two, with feeding being the more pleasurable of the two by far. Feeders do not require sleep, and have a nearly infinite amount of stanima and endurance as long as they have even a drop of cum left in their sack. Any unspent cum will gradually dissolve into a futanari's body, causing no harm of change to them during the process, and with the only effect being an increased libido for a short while.
Finally, consumers are "ordinary people" who can only find nourishment through the consumption of a feeder's cum. Drinking the milk directly isn't viable for them. As there are at least 2 consumers per ever feeder and producer, the world has adapted around accessibility for consumers. Feeding restaurants have become a common workplace for the other half of the human race. And while a proven misconception, it has become a popular belief amongst consumers that a futanari's physical attractiveness and dick size is relevant to the quality and taste of their cum. This is scientifically incorrect, and there is only a very slim, more or less negligible, difference between two different futanari's cum. Though cleanliness has shown to have an effect, with clean being heavily preferred.
It is also a consumer's job to take care of the other half of the population. This includes running most points within society. They also are incharge of raising the young until they develop into their adult forms. And a consumer will not eat more than or less than necessary. So over consumption will never happen.
With that all set in place, all that was left for Jeff to do was to establish his own role in the new world.
