Welcome to the time of the New Order. In the year 2065 women came to the point where they realized men were not necessary for maintenance of society. Men were the ones who wanted guns mostly, who raped, who committed that largest amount of crimes, and represented the largest majority of prisoners. Women were tired of dealing with men's incessant needs and childishness. When finally they were no longer needed for creating children, and genetics could be modified well enough women outlawed men, exhiled them to specific cities in the country, and took over politics, healthcare, and industry.
The world ran by women got off to a bumpy start, a violent start, but in the end with technological prowess no longer available to men they were able to beat off waves of men who refused to accept the New Order of things. Eventually the men began to accept their positions and adapt to the new circumstances until they slowly faded away in history books. However women were not done with men entirely. Many scientists, behavior specialists, etc wanted to use a stock of expiring people with few rights and conduct testing. Better to do so on a stock doomed to go extinct and perfect it there before moving on to public release. Other women simply snuck in to be with them for a short time until it became too dangerous, and finally small bands of men would occasionally sneak out to invade and steal from surrounding cities... these men got the worst testing done on them.
Here are just a few stories of men who willingly or unwillingly ran into the Metamorphosis Squad, responsible for rounding up escapee's and giving them an experience that they will never forget or escape from. The M Squad is given access to special tech designed for all possibilities, nanites, harnesses, conditioning techniques etc. Depending on the attitude and personality of the person they capture escaping the custom alter the individual in whichever way seems best to not only teach them a lesson, but to integrate them into the women's society to serve or be displayed for uniqueness.
