Mindy decides to put her time-out to use, in relieving the growing pressure in her bowels. She sits forward on the plastic chair, releasing most of the pressure previously squashing Allison into the seat. Initially, the diaper-girl is relieved. Moments later, a wet *BRAAAP* from the girl's buttocks ends her tranquility. Immediately after the rotten-egg sulphurous wind passes into Allison, liquid shit sprays into her interior padding. A large turd begins to broach from Mindy's cheeks, pressing Allison in an altogether different way that before. "!!!... Oh... That's... Fucking disgusting!" Allison thinks. She can taste every bit of the waste being smeared over her interior padding, as if it was her tongue. The taste is a nasty melange of bad cheese, rotten eggs, and spoiled veggies, all combined with the rural undertone of fresh manure. Allison's already-swollen body tents out around her rear half, her whole body now tasting like a toilet bowl.
Mindy's face strains as her body pushes the remains of last night's dinner and her breakfast out into her pants. Her loose-fitting summer dress covers the bulge her waste has created in her Pampers. As soon as the largest part of the turd has entered her diaper, she drops her head in relief, locks of her light brown hair falling loose over her face.
Bella's mother doesn't immediately notice the change in the girl's demeanor, however the smell soon alerts her to Mindy's mess. "Phew... Mindy, did you make a present for me too?" The girl turns around to look at the mother, cracking a small smile. Then she turns back to look at the corner, idlily drawing her finger against the texture of the wall.
The girl's deposit into Allison has finished. Now, the diaper-girl finds herself hugging the solid and mushy warm waste against the regular girl's behind. The suddenness of the situation has left Allison somewhat paralyzed, unable to move or resist tasting her dirty contents. "... Ugh... Gh..." she internally vocalizes. If she had a stomach, it would be now emptying itself, but she now simply exists in order to taste and contain the young girl's waste.
The smell continues to permeate the room. "OK, hun. Your time-out is done. I need to clean-up your stinky butt, ASAP," Bella's mom comments, scrunching her nose at the growing stench. Mindy twists around and stands up, unconcerned about her loaded underwear. She waddles over to the mom, Allison swinging with the mass of her contents. The waste squishes into previously-clean corners of the diaper-girl with every step. Bella is still lounging on the couch, dramatically holding her nose. She continues to watch TV, but gives the occasional sympathetic glance over to the stinky girl.
Sighing, Bella's mom gets up and grabs a caddy with all the diapering supplies she put away not that long ago. Mindy stands uncomfortably and watches as the woman spreads out a mat and gets out a pack of wipes. Along with Bella's pull-ups, the caddy contains some of her old unused diapers, for friends and emergencies.
For the diaper change...
