"Wonder what this will do..." Sam muttered, picking through some options.
"What's that?" Ian asked.
"Oh nothing, babe!" Sam replied as she entered her option - a one-way body swap. So, she would be swapped into Ian's body, and her own body would go on autopilot.
She hit the button, felt her vision blur briefly...

Sam opened her eyes. She was still holding the DS. Did that mean that she had done something wrong? No... something definitely felt different. She looked down, and sure enough - Ian's jeans.
"So it did work!" she said, noting the male voice coming from her mouth.
"What worked, babe?" Sam heard herself reply. "That silly game?"
She looked over at her own body, apparently acting on its own volition. It was weird looking at herself, but then if she was inside Ian right now that was to be expected.
"Yeah, it just did something cool. I'll show you later when I figure it out." Sam replied to herself. Her head swam with possibilities, some of which were more lewd than others.
"Let's try..." she grinned, before entering her own name.
One touch, and she watched as her old body grew taller. She's always wanted to be a bit taller than she was, but it had never really been a possibility.
The next few things she entered were largely driven by a lust for power, and ... well, just lust. Her new body's hormones were getting to her, and combined with the power to control her own body...
After a flurry of transformations, she stared in awe at her old body. Tall and thin - still goth in style, but a lot sexier. Knee high boots and a black leather miniskirt, a black and white striped crop top that stopped only a bit below her generously augmented D-cup boobs. Her hair was now long and sleek - still black, but with purple highlights. Her face remained largely unchanged - better skin, less pimples, but otherwise the same. Still wanted it to be her, after all.
The newly transformed Sam looked at her boyfriend with a sexy glint in her eye and smiled. Sam-in-Ian felt a brand new sensation in her pants as her new body reacted to the sight of her old, upgraded body. She returned the smile and looked at the DS again.
