"Hmmm... What if I turned myself into Melissa? That'd be an interesting way to test it." He thought about it. It would be interesting being his sister. His sister was beautiful; Long blond hair, a beautiful, curvy figure, and big breasts. He had to admit it too. She was hot. "Alright. I'll try it."
He began to input the settings. First, he went into the Gender mode and set it to Female. He edited the hair, IQ, and the physique of the settings, and added some clothing, and then the 3D image on screen looked like a perfect replica of his sister. "That should do it."
He took a deep breath. "Okay. If it does work, I can always change myself back with the Revert button. This is just to test it out." He hit the Ready icon on the screen. The gun began to glow. He pointed it at himself, gulped, then pulled the trigger. A blue glow was emitted from the gun, and it enveloped Jake.
Jake's eyes shut. He felt a bit scared. Slowly, he opened them, and... nothing happened. "What? Nothing? Ugh, what a gyp. I can't believe a piece of crap toy like this would've wor... Urggh..." Jake's body started to feel weird. He began to moan a bit. "Is it... working?" Feeling something crawl down his neck, he felt and discovered that his hair grew to the middle of his back, and now was blond. "It's working... Whoa! My voice! It sounds just like..." He was interrupted by a pain in his chest. His chest began to swell up, forming 2 perfect breasts. His body began to tingle all over, as a new feminine figure appeared. "AHH!!", he screamed. He felt so strange. And finally, the change was finished, as his dick began to sink into his body, forming a vagina in its place. His, or should I say her, clothes then changed into a typical outfit Melissa would wear; A low-cut T-shirt and a pair of jeans that perfectly showed off her figure.
The change finished, Jake walked into the bathroom. Looking into the mirror, she was surprised at her sister looking at her. "It works! It really works! Wow, this is amazing. Wonder what I should do with it now?"
