Charlie's on his first space walk, patching some holes on the outside of the International Space Station, when he spots a mysterious purple cloud floating through space and heading his way. It's coming too fast for him to head inside. It envelops the ISS and him, and his body begins to change. He becomes a woman!

At first, he's dismayed by this impossible development, but once he realizes that this new body may help him catch the eye of Sara, his lesbian mission commander, he figures things are not all that bad. He decides to enjoy his gender trip and make his fantasies come true. With Sara's help, he discovers the joy of being feminine.

But the alien cloud is not finished with the astronauts aboard the ISS. What is it, and what are its intentions?

Author's note: This is a standalone gender swap and feminization story with a HEA ending! Two bonus stories, Guinea Pig and The Reluctant Wife have been included as thanks to my readers.

Warning: This 15,000-word novella contains graphic language and steamy descriptions of gender transformation, feminization, and sex.
