"No, you're lying!" Leah said firmly. "I hate being a baby, why would I want this?"
"Aren't you listening? This is your deepest desire," her reflection said patiently. Leah jutted out her chin.
"You're wrong."
"Am I? Well, looks like I, or rather we, don't have a choice," Leah's reflection said. Leah felt the static return. When it faded, to her horror, she watched herself squat and grunt, somehow acquiring more poop from somewhere and shoving it into her diaper.
Leah gasped between grunts when she felt something trickle down her leg. She was leaking! But she continued to push, the force behind them growing until she found herself on her hands and knees, grunting loudly as her over filled diaper was subjected to more mess.
"You'll thank me," her reflection said. There was another static. Tina burst into the bathroom. At the sight of Leah on the floor, she did the worst possible thing. She cooed loudly.
"You are just a cutie when you have a blowout!" Tina gushed. Her eyes watering from the smell, Leah finally finished with a salvo of urine. Tina picked her up. "All right, let's get you cleaned up. Then you can put on your diaper, since you're such a big girl!"
"Uh, cleaned?" Leah asked. Before she knew what was happening, she found herself stripped down and in the tub, being scrubbed by Tina.
It was...nice? Leah just had to sit back and relax as Tina cleaned her up, then toweled her off. Then she grabbed Leah's mess from earlier and brought it outside while Leah diapered herself.
"So?" Leah's reflection asked. Leah glared. "You have to admit, that was nice."
"...I guess," Leah said reluctantly. "But I don't want to be a baby!"
"Look, until you accept that this is what you want, you'll experience more and more warps out of your control," her reflection said. "Forcing you into the role you deny you want. But if you accept it, well, then you decide when and how the warps happen."
Leah stood in the bathroom in her clean diaper, trying to decide what to do. Her reflection smiled.
"Tick-tock. Tina will be back soon with a very cute outfit. Decide now. Do you accept your desires and thus take control of them? Or reject them and thus continue to spiral?"
"I..." Leah swallowed. She could hear Tina's footsteps outside the bathroom. She had to make her choice now.
