The Futanari War — CHYOA An alien race, who call themselves the Futanari, invade Earth, turning every female human into their race while hunting down every male on the planet to enslave and/or fuck. How does this affect the individuals on both sides? The setting is similar to War of the Worlds and Terminator, but with Amazonian Futas. Each story branch follows a person, they be human or Futa, in this post-apocalyptic piece, where the last of humanity is trying to stay human, while the Futanari think they're trying to help evolve the human race.
