Aya is having some little time, coloring on the floor - but she doesn't need diapers. She's a "big girl" and panties are just fine for her! Step-Mommy Apple comes to check on her, and reminds her to use her potty chair like big girls do, but Aya doesn't want to yet. What a silly girl; it doesn't take long at all before she realizes she does need to go, and now her Step-Mommy isn't there to help her. She urgently tries to make it to the potty, but getting her pretty skirt off is just too hard! By the time she gets it off, it's too late. She can't stop herself from peeing! Now her panties are...

Aya is having some little time, coloring on the floor - but she doesn't need diapers. She's a "big girl" and panties are just fine for her! Step-Mommy Apple comes to check on her, and reminds her to use her potty chair like big girls do, but Aya doesn't want to yet. What a silly girl; it doesn't take long at all before she realizes she does need to go, and now her Step-Mommy isn't there to help her. She urgently tries to make it to the potty, but getting her pretty skirt off is just too hard! By the time she gets it off, it's too late. She can't stop herself from peeing! Now her panties are soaked, and she's standing in a big, wet puddle! Luckily, Step-Mommies are good at taking care of accidents like this, and Aya's Step-Mommy knows just what to do. Step-Mommy isn't even too upset with her little one as she gets her out of her wet panties and wipes her all clean. Aya is pretty upset though, because now Step-Mommy is going to put her back in diapers! Aya feels more and more upset and ashamed as Step-Mommy sits her on a diaper and finishes stripping her naked, covering her "big girl" parts in baby powder and wrapping them up in protective padding. Aya isn't happy about it, but now Step-Mommy won't have to worry about any more accidents.

After being put back in diapers for her failure to make it to the potty and wetting her panties, Aya is trying to make the best of things by getting back to coloring with crayons. Before she knows it, she's managed to wet her diaper too! At least now Step-Mommy doesn't have another reason to be upset with her. In fact, she wants to give Aya a special surprise with her diaper change. Step-Mommy puts a pink buzzy toy inside Aya's next diaper, and uses it to show her that being diapered isn't so bad. Step-Mommy makes Aya cum in her fresh diaper and gives her a big hug for being so cooperative.
