Extremely infamous erotic story which floats around the internet, in which an evil/perverted Witch Queen named Zorelle captures Supergirl and enslaves the world. Various other superheroes from various DC Comics attempt to save her but they all end up trapped in various situations involving sex toys.
The story has never been completed but the author did change all of the names to protect the copyright (for instance making Supergirl into Supergrrl). Generally speaking the story is really heavy on rubber. I won't go into details, but there's rubber everything. Rubber brothels, rubber nuns, rubber insane asylums, rubber cows, hell, even rubber travel offices.
Other than the main superheroish characters, there are an array of mundane human beings that get themselves into all sorts of bizarre predicaments, usually by signing silly legal contracts where the fine print does something silly like make them into sex slaves, or into the rubber raft on the rafting trip they intended to go on.
Of course Supergirl does set everything straight at the end, but then the author is too lazy to finish writing the damn thing so she hasn't quite gotten around to THAT yet.
