Katie and Tiff decide to hit the merge button. They never quite new why but they felt like they were the same person at times. They then went into the chamber, and it starts merging Katie and Tiff into one councenness and body.
It had just finished merging them when:
"Error Test number mismatch"
"Auto fixing error"
The Kaite-Tiff mind felt being stretched apart. The combined persona realized that it was not separating them but cloning *her*.
"Error fixed successfully"
The machine had finished cloning *her*.
"Applying previous setting for duration of change: Permanent"
"Oh crap" said both Kaite-Tiff's.
"Merge complete"
With that the power goes out. They started to feel them selves up and down. They realize that the machine automatically took the most sexy and appealing parts of Kaite and Tiff's body.
