One day everywhere on the entire planet earth, war, poverty, world hunger, and all the other problems the earth had, suddenly stopped. Some might've thought it was a miracle, if they did not know the truth. All of the war, poverty, etc. stopped because of an alien race, known only as the Lustlords, used their technology to reprogram the minds of the people (and even the animal) of earth to be their servants, and slaves.
No one resisted as the Lustlords took over and established their rule, for they already were the rulers of the world, even before they officially declared it. Now the Lustlords weren't called that for nothing, the first things they did after establishing their rule is abolishing all laws against sex, nudity, and even deification, and of course the newly reprogrammed humans and animals were very happy about that.
After the Lustlords finished changing earth society to their liking they gave it back to its people, left them with all the tech they needed to be incorporated into thier interplanetary society. With several species from several planets, all of whom have no sexual taboo (well except for gore and death), but varying levels of love for certain fetishes, it is certainly fun.
Shall we follow a human, or one of the many other species of this society, and what kind of kinky stuff will we see?
