Gender fluidity epidemic

Welcome everyone to Marywood, a city with around 80k people. Life in Marywood is pretty good; the city is wealthy, the citizens are happy and the city's university is striving with young scientific talents graduating regularly. But maybe, just maybe, this was also the problem. Because, in this spring, a mysterious virus contaminated the city's water supply and within a week, it was assumed that every single citizen was contaminated. The government decided that the whole city would be quarantined and noone could enter or leave the city.

But what exactly does the virus do? It messes with the person's gender, but how does this work?

The virus makes it possible to adjust your gender to how male or female the thing you are doing right is, in your opinion. That means, if you think cleaning is a female task, you become more female. And if you think, fixing a car is a male task, you become more male.

For men that means, whenever you finish a task that you think is a male task, you gain about a quarter of an inch in dick size and gain generally more male features (wide jaw and shoulders for example). If you do a more female task, you lose a quarter of an inch in dick size. When you've reached zero, you become female.

For females that means, if you perform a female task, you become visually more feminine; wider hips, bigger tits, more feminine facial features. Performing male tasks will make you become less curvy and a little more bulky, until your chest shrinks to smaller than an aa cup (also you grow/shrink a quarter size at a time), which is when you become a man. Also, your holes can take bigger cocks when you're more feminine.

When this information aired on the news, the reaction of the public was...hysteric. Everyone became worried of turning into the other gender and especially men were very afraid of becoming women. Therefore, society became a huge game of power with everyone trying to outsmart or outpower the other person in order to stay who they are.
