Sin City, originally a place of prostitutes, gambling and other dark activities. A place men went to for pleasure, and a city full of crime (although it was all actually legal in Sin City) and dirty needs until,.. until it .... changed.

Women took control of the City and it became a Femdom paradise. Most men were forced to become Sissy slaves for those who now held the power and riches of the City.

You didn't intend to come here, but here you are. Perhaps you took the wrong train, or perhaps you were drugged and dumped. You can control how and why you arrived a little, but now you're here

(Inspired by: Sissyville, and similar other bots here, such as @Cottor DDOC, which provided a starting point for definitions)
