When light finally returned to her eyes, Jenny found herself sleeping in the arms of something super soft. Something about her body felt different... wrong. Of course, something about these soft arms she was being cradled in felt very right... Her vision felt a bit too fuzzy to tell for sure, so she tried to rub the blurriness out of her eyes.
She realized that her hands felt very small, almost as though they would have belonged to a three year old. In fact, as her vision returned, that's exactly how they looked. She let out a squeal of surprise, realizing that her voice had gotten higher. Suddenly, the soft arms cradling her brought her face to face with what looked like some kind of fox... an anthropomorphized fox. Its eyes were strangely human looking, and it smiled at you practically maternally.
"Aww, did Jenny wake up from her nap?" the fox face asked in the voice a mother might use for a baby. It nuzzled its nose under Jenny's chin, making her giggle involuntarily. She planted a kiss on her forehead before saying, "I'm gonna check your pants, okay?"
Wait, check her pants? Jenny was suddenly acutely aware of the fact that she was wearing a diaper. Her face went red with confused embarrassment as she was turned around and her diaper was pulled down.
"Huh? Well look at that, you're clean!" the fox lady exclaimed, "Jenny, real quick, do you feel like you need to go potty?"
"Potty?" Jenny asked.
"Yes, baby," the fox lady cooed, "Could you go potty in your pants if you need to? Please?"
"In my dipie?" Jenny asked again
"Only if you really need to," the fox said, "That's where humans go potty, right?" She was set down on the ground, and she immediately toddled away to find a mirror. There was a large one in this fox lady's living room, in which she discovered that she'd turned into a three year old girl... but she still had her boobs? She was dressed in a baby-fied version of her cheerleader uniform that did nothing to hide the large diaper that swaddled her bottom. She was in a little bit of shock. She was so shocked that she actually made use of her diaper.
"Oh? Did you use your diaper, Jenny?" the fox lady asked.
"Y... yes," Jenny said, her face flush with embarrassment.
"Well don't worry, I'm here to change you," the fox said, striding over to scoop Jenny up. Jenny took in that the fox lady was like her nanny or something, and that she'd turned into a three year old version of herself with boobs. She soon came to realize, or otherwise remember that all of humanity had been transformed to never age much past three, and that they were all still in diapers. They were taken care of by soft furry creatures like dogs, cats, foxes, bunnies, raccoons, and more.
