Dustin was in the backseat, playing with a toy robot with a look of joy on his face. He doesn't seem to remember being a teenager at all. He was wearing a red shirt, and a pair of overalls with snaps on the crotch, which allowed for easy diaper changes.
Looking at him play with the robot gave Ty an idea.
"What if I change myself?" He thought, looking down at his hands "I could always wish myself back... Why not have fun with it?"
While the possibilities were endless, there was one particular wish that he thought of that intrigued him. He caught himself wishing this before he had whatever power this was... though it somehow slipped his mind until now.
"I wish..." Ty thought, bracing himself with a pause "I wish I was a girl!"
Suddenly, she felt her body morph and shift in many dramatic ways. Her arms became slightly thinner, as her shoulders became less broad. On the opposite spectrum, her legs thickened to accommodate her widening hips, her butt also becoming fuller. Her hair lengthened, falling down to just above her shoulders, smoothening out in texture, the color becoming a rich hazelnut, as opposed to the dirty brown the former boy's unruly hair used to be. Two mounds sprouted off of her flat chest, growing to around a high B, like her mom. Finally, she felt her genitals morph away, forming a fully functioning vagina.
As she felt her body slowly stop changing, she noticed that her outfit also seemed to change to accommodate her new proportions. Her outfit was now a simple graphic tee, and skinny jeans, her beat up sneakers turning into nice new ones. Ty also felt what she guessed was a bra under her shirt, as her underwear morphed into more appropriate ones.
The transformations stopped completely, with both her Mom and the teenager-turned-toddler completely none the wiser.
"Woah..." Ty thought to herself, still processing her transformation "this feels..."
"... INCREDIBLE!"
"This feels so... Right!" She thought, having to restrain herself from squealing and making a scene in the car.
She couldn't find the words for it, but she felt... Complete? Whole? Again, Ty struggled to even articulate her thoughts, but one thing seemed clear.
"I am totally not ever going back to being a boy!" She triumphantly announced in her head a smile beaming on her face.
She knew the term for what she was feeling. It was... Train gender? No, transgender... she has a habit of falling asleep in Health class... The only thing she remembered was a few of the guys looked disgusted, and got sent to the principals for calling them freaks. Luckily for her, the world seemed to have changed it's perception of her, so she's now always been a girl to everyone else's eyes...
Just then an awful smell filled the car, making the girl gag.
"Ew!" She exclaimed, her new voice catching her off guard. Her mother smelled it, too, but was either pretending to not be dazed, or was used to it.
"Poo poo!" Dustin babbled in the back, slurred through his squeaky toddler voice. Guess that answers where the smell came from.
"I guess this was to be expected..." Ty's adoptive mother remarked, looking at the diapered boy through the rear view mirror. "There's a gas station ahead. I'm going to pull into there."
Luckily, there was a gas station shortly ahead. The second the car stopped, Ty swung her car door open, taking a few deep breaths of the clean, unsoiled air.
"I'm surprised you aren't used to it yet..." Mom remarked, trying not to laugh "you've had 3 years to get used to that smell..."
Ty only gagged on response.
"Hey, Tyra." Her mother said, seemingly addressing the newly minted girl. "I'm going to change your little brother. You could go into the gas station and get some snacks, if you want. If you do, though, I want a Dr.Pepper."
She nonchalantly hands Ty a 20$ bill, seemingly not noticing the look of shock on the girl's face.
Her mom then leaves the driver's seat, leaving Ty to her own devices.
"Mom never gave me money so casually!" She thought, looking at the bill as of it was gold. She couldn't tell if this was because she was now the oldest by a significant margin, because she's a girl, or both, but it was a welcome surprise.
She looked at the bill, hearing her mom open the back of the SUV, grabbing a diaper bag from the back.
Looking at the diaper bag, then at the bill, Ty had an idea.
"If I get more attention now, how much can I get if I need to be taken care of like my now younger brother?" She thought, trying to think of a wish.
She the wished ...
