"All right, all right. Fun spoiler!" Tiff says as he backs away from his friend. Katie's face lightens up, he really was begining to feel uncomfortable and he can't wait to be his real female self again. Tiffany actually felt even more repulsed by his current form. He really doesn't want to be a guy, he loves his femininity and would never give it up. He only reluctantly agreed to become a guy too hoping he'd have some fun with male Katie, but now he's getting a better idea...
"So let's head back downstairs ok? This is fucked up, I want to change back" Katie pleads insistingly.
"Yeah me too, you're right this was a bad idea. Let's go"
The two naked young men hurry back to the room with the machine and Tiff tells Katie she wants to go first. Katie reluctantly accepts and she sets the controls on the panel as Tiffany steps inside the contraption. Seconds later the lights go out and the smoke clears, and Tiffany steps out of the machine, restored to her real self. She ran a slender hand through her long, straight, light brown hair, felt her beautiful smooth face and looked down to check every part of her busty, sexy body was back to the way it should be. God she loved her body! "Good riddance!" She says in her feminine voice and flashes a beaming smile at Katie who was waiting there impatiently by the control panel.
Tiff was standing there, fully naked and man did she look hot, Katie found herself thinking. She felt an erection coming and she immediately panicked, what the hell is she thinking? "Okay okay Tiff, you look great, but my turn now, all right? I just want to be myself again!"
Tiff nods slowly and smiles a wicked smile as she goes to the control panel. "Okay Katie, step right in"
Katie gladly does as she's told and gets inside the machine, impatient to be herself again.
Tiffany however had something else in mind. She giggles mischevously as she types in some commands and starts up the machine. As the smoke starts to engulf the inside of the cabin, she feels herself getting aroused with anticipation.
Seconds later, the transformation process is complete and the machine's door opens.
"Oh Katie? Come on, step outside so I can see you" She calls to her friend, arousal coloring her voice.
After a couple seconds of silence, Katie answers. "Uh, Tiff? I think something went wrong..." The voice, which clearly belonged to her friend Katie, didn't sound much like Katie though, definitely didn't sound female, that's for sure.
Tiffany grins lustfully and when "Katie" finally walks out, and she lets out a pleased "OH!!" in seeing "her". She had transformed Katie into...
