Fox Apocalypse TF

The world has descended into chaos ever since a new airborne illness had appeared. There's a scientific name for it, but those who are left alive just call it "The infection." The infection originates from a fox's pheromones. We don’t know how but it has spread to humans like a virus. Anyone who becomes infected begins to become a fox. It usually takes a lot of exposure to fully claim someone. Essentially, breathing in the foxes pheromones transforms you little by little, up until you join them. Though it's a lengthy process. The infected are split into 2 categories: The first, and way more common of the two are the fully claimed infected, practically indistinguishable from an ordinary fox. Except for 2 things. The first being, they're very very horny, though they usually use eachother to take care of that, at least for awhile. The second difference is that they want with their whole being to infect any human they find. Doing whatever they can to make a human breathe in their musky pheromones. They don't have any memory of their human life. Nor do they have any desire or will to find out about it. The second, and almost impossible to maintain category of infected aren't entirely claimed. This strain occurs when someone is freshly fully transformed. Infected retain their sense of self fully, just being in the body of a fox. That is, until they feel the heat of their new body. As the infection only progresses to the brain as soon as their new body shows signs of being in heat (for males, when their penis leaves its sheath. For females, it's when their vagina starts to get wet.) They lose all self awareness and join all of the first category infected. The way you can tell the infected apart by their eyes. Category 1 infected have fully black, feral fox eyes. Category 2 infected have incredibly human eyes. Wearing a mask can keep someone from breathing the pheromones thankfully. The world has fallen apart, buildings broken, streets filled with mating foxes, and stragglers who have survived the infection.
