The confusion on Tina's face was unmistakable: she was expecting Leah to have accidents, sure, but this far surpassed her expectations. How could she have let things get this far? Ever since she that accident in the store that day, she's continued to spiral downward further and further into babyhood. What should've just been a simple (albeit embarrassing) accident she could've explained, it turned into dressing like a toddler, which turned into acting like a baby for a day, which turned into having accidents to sell her role, which turned into being convinced to spend a week in diapers and dressed as a toddler for convenience. She was starting to get used to diapers, and now was actually starting to have accidents. She didn't even mind the clothes! How did she let it get this bad!? Leah grunted as, despite still being horribly embarrassed, she continued to make potty in her pants. To add further to her humiliation, her bladder released and thoroughly saturated her diaper.
"Goodness gracious, that's not Leah is it?" She heard her aunt speak, still not gaining to nerve to meet the woman's eyes, "I knew you said she was having some accidents, but this looks more like a baby than a teenager."
The statement was too much. Her teenage mind subsided to allow the most basic, primal instinct to rise to the top. Every infantile situation she's been in has been her own undoing, and she can't see it ending anytime soon. Why try and fight it? Like watching a train crash in slow motion, Leah watched as she raised her hand to her face, and jabbed her thumb into her mouth. She knew how infantile she looked, but with her clothes and used pants there's really not much further shame she can add to herself. Here she was, looking like a baby and smelling like a baby. Is it really a surprise if she starts to act like one? The fact that suckling brought an immediate, and tangible sense of calm only confirmed it further; she really has let herself become such a baby!
"Oh gosh, umm...do you mind if I change her inside?"
"Oh, be my guest."
Leah didn't have much input as a distressed Tina picked her up and carried her inside; well, besides continuing to poop her pants and sucking her thumb harder. She couldn't meet her eyes as she continued to grunt behind her thumb. Eventually she was placed flat on her back on an elevated surface, one she hoped wasn't (but knew probably was) a changing table.
"Finish up." Was all the woman said, and Leah obliged. She was forced to pull her knees to her chest, pushing with all her might to pass the stubborn log. At one point, Tina had removed Leah's thumb and replaced it with a pacifier. Because of course she did. And Leah continued to suckle it like her life bepended on it. Because of course she did. Finally, with a resounding fart, the log fully exited into her now incredibly messy diaper. That's should've been it, but of course more followed. Leah was once again involuntarily emptying her bowels with a series of nasty farts. Where had this come from? And more importantly...how come she only felt it when it was right at her exit?
"Oh goodness, Leah, you still have more?" Tina asked in disbelief, "I don't understand! Why didn't you mention you needed to go? Why- why are you acting like this?" Her voice, though confused, was far more worried than angry. As the sputtering facet that is Leah's ass finally trickled to a close with one last fart, the teen baby reluctantly removed her pacifier.
"Tina, I...don't know. I don't know what's happening to me, but I don't think it'll get better. I think it'll get worse." Tears tugged at her eyes as she realized this. How could she hang out with her friends, or go to school with a binky and a stinky diaper? Could she even course correct by this point? Tina let out a sigh, concern evident on her face as she began to change Leah's diaper. The teen didn't even object, just turned away and returned the pacifier to her lips.
"Well, Leah, we could..."
