Cody decided he wanted to try using the remote on himself and went to his room, shutting himself in and locking the door. He looked at it for a moment and then had an idea for what change to try. He'd found out this thing could change someone's gender, so... why not try changing his own? He had wondered sometimes what it'd be like to be a girl, plus he knew for a fact it'd work.
He tapped 'Set Age' up one to 16 so he'd stay the same, and then clicked 'Set Gender' to change it to 'Female'. Aiming the remote at himself, he clicked 'Transform Now', and the red beam of light struck him in the chest.
A split-second later, Cody felt a weird turning in his stomach as he began to transform. His skin felt sensitive, and his clothes chaffed on it, especially his T-shirt against his chest. He pulled it off, and in the mirror he watched the first big changes become apparent. His nipples swelled and expanded, suddenly sensitive to the touch.
Cody's body seemed to slink inwards in lots of places, his muscles turning more lithe and his figure forming curves as his shoulders narrowed and his hips widened. Before his eyes, his face shifted around, his features softening and his thin layer of stubble vanishing, his hair lengthening and his lips turning puffier. "Whoa, I really kinda-" he started to say, only to gasp as he felt the bulge of his larynx recede and his voice increase in pitch. "-I really kinda look like a girl now," he said in his new feminine voice. In surprise, he added, "And now I sound like a girl, too!"
His newfound femininity now came to assert itself in the most distinctive places. Cody bit his lip as he felt mammaries form in his chest, with mounds of soft flesh emerging. The boy watched with amazement while he sprouted breasts, the sensation of having them unlike anything he'd ever experienced. His chest seemed full of sensitiveness, like he wanted to have it played with and sucked on.
Once his breasts had finished growing, the sensations migrated further down, and Cody's eyes were drawn between his legs. He stared at his penis with fascination as it shrank back into his body, the large six-inch shaft tapering off gradually to a tiny nub around which all the sensitive nerves bound. And under it, his scrotum and the testicles which hung inside it were tugged inwards and reshaped, his balls sliding into place inside him while a slit peeled open between his legs.
With Cody's body totally changed, something clicked in his- or rather, her- head. He was not a boy anymore, she was a girl. Even though she remembered being a boy, she felt like she'd always been a girl, with memories and knowledge and instincts that this version of herself had flowing through her mind. For one thing, she knew her name: Cassidy.
"I wonder what to do now," Cassidy said to herself.
