The Futapocalypse

The day this began was rather odd as it came from outer space. The world was going chaotically as usual, but then a meteor crashed down right in front of the White House. The president and his family were moved to safety, but when the scientists begin checking it out that changed everything. A scientist named Nina was the first to touch a rock without a set of gloves on and it was her big mistake. She went home already sweating and about to pass out, but her crotch was almost burning. Finally she fell onto the floor holding her crotch yelling at first, but then she found herself moaning. Nina looked down as a cock began growing on her and it didn’t stop. Her cock was gigantic and she needed to cum fast! Immediately she ran outside and banged on her neighbors door. When the man answered he and his girlfriend seemed worried, but she pounced on him. His girlfriend screamed as she began face fucking her boyfriend. Nina slammed the door shut with her foot and looked up at the woman. Finally once the shock was over the woman ran for a window, but Nina pounced on her. Nina rammed her cock inside the woman and began using her. After using the two for a few hours the woman had grown a cock and her once boyfriend had turned into another futa.

The infection began spreading across the globe, and soon majority of the population was constantly horny futas. Some began fucking each other, but the hunt for people who weren’t infected were needed.

(Now, I will have a femboy alternate start.)
