Leah had to contend with the facts: she was (most probably) hypnotized to become a baby, which gave her a desire to wear diapers. While wearing a diaper, she will use them. As such, the reasonable action was to just resist the hypnosis and not wear diapers; now that she's aware, fighting off the desires will be easier, at least until she can undo the hypnosis or it wears off. That's the reasonable action.
Leah...did not feel particularly reasonable at that moment, she was feeling bliss after uncontrollably wetting her diaper. Embarrassing desires and actions aside, it didn't feel like a bad thing done to her. She recalled the moments before the tv aisle, when answering questions. Her answer did end up being 'become a baby' from her own truth, whether she liked it or not.
If she was being introspective, the prospect of being a baby and no longer fighting to be seen as mature was not...a terrible one---it actually sounded kind of nice. She once again remembered that hypnosis doesn't make you do things you don't want to do, and that her inner truth under trance came to 'wanting to become a baby'. With all that in mind...it seemed like Leah secretly wants to be a baby, or baby-like at the very least. The hypnosis might be forcing her hand a little, but it was still HER mind doing all the work; when thinking on how she felt just wetting a diaper like a baby, she couldn't deny that she enjoyed it.
Leah sighed as she sat back up, giggling as she squished her diaper. Why fight it if she enjoys it? It's not like anyone else needs to know. If she keeps it a private hobby, then that's her business. If she wants more? She has time to explore this new side of her, there's no need to rush.
She removes the tapes of the diaper, carefully lowering it to the floor; she'll need a discreet way to get rid of these. For now, it stays in a spare plastic bag in her closet, along with the rest oo her hidden junk. Her skin is still covered in pee, so she decides to put on some panties and bottoms and head over to the bathroom to clean up. As she does, though, her eyes catch her hidden stash of diapers peeking out. She walks over to reposition it somewhere less visible when the idea strikes her: should she just put another one on?
It's stupid, and could get her caught, and might very well make her wet the bed, but...she kind of likes that? At least some of it.
Leah let's out a sigh of defeat as she's forced to accept she's now a bit of a freak. She rediapers herself and squeezes on some pajama bottoms before jumping into bed, finding it extra comfy thanks to her pillowy underwear. She let's herself enjoy the feeling all the way until sleep claims her.
In the morning, her alarm woke her up from a deep sleep. Despite being up a little later, she still feels refreshed. She also thinks she feels something else...
