The Worst Smell

Bigger...?

Supplies in hand, Holly positioned herself in front of Holly's spread legs, looking down at the diaper with disgust as though it were some abominable creature. She could practically see the stink emanating off of it, and her eyes watered as she knelt down. She set the supplies to the side and moved her head around the diaper, first to the left, then the right, wondering where she was even supposed to begin. How am I supposed to reach the damn tapes?! she wondered. She found it impossible from her current position, so she stood back up and leaned forward over the girl. She leaned out over the bulging diaper and reached for the tapes, but they were just out of her reach. Even on her toes she could just barely graze them.

"Come on, come on- AH!"

She had leaned just a bit too far and lost her balance, and time seemed to slow as her body fell forward toward the diaper. You've gotta be KIDDING ME! A moment later, she fell face first into the brown, stinking padding.

SQROOOOOORSH

The diaper let out an otherworldly noise as her upper body squished down into the diaper like it were a memory foam mattress, the mess spreading out beneath her. Her nose was overpowered by the stench separated by only an inch or so of material, which was only made worse by her mishap as a fresh plume of odor was released into the surrounding air.

"Ahahahaha!" Rachel was hysterical now, taking great delight in her sister's blunder.

"Oh God... I don't think I can take much more of this..." Holly couldn't even acknowledge her sister's blatant joy at her expense. She felt the color drain from her face as her constitution weakened against the thick, overpowering stink. "That does it. I'm getting a clothespin." She tediously maneuvered herself off of the mush-filled padding, causing it to squelch and gurgle with every movement of her body. Rachel simply watched with great amusement as Holly managed to pull herself to a standing position. She went to the kitchen and pulled open a drawer with various supplies in it, locating the clothespin she so desperately needed to finish her duty. She snapped it onto her nose and winced a bit at the pressure, but was relieved significantly as the effects of the smell became less harsh.

With newfound confidence, she strode back into the living room where Rachel still lied. Okay... You can do this, she thought. She cracked her knuckles and rubbed her hands together. "Alright, stinker," she said in a nasally pitch. "Time to get this thing off you once and for all." This time around, she opted to stand at one side of Rachel as she untapped the diaper. She undid the two on Rachel's right side, then reached over the girl and did the same on the left. But then, just as her fingers had made contact with the front waistband of the diaper, another loud gurgle emanated from Rachel's abdomen. So loud, in fact, that even the nick knacks on the shelves rattled at the noise.

"Ooooohh..." Rachel doubled over, grasping her stomach and gritting her teeth at the noise.

Oh, you gotta be KIDDING ME! Holly had taken Rachel's earlier rumbling for a fluke, but now it seemed to be back with a vengeance.

"Unnnghh! Up! UP!"

Ah, shit... Holly remembered that Rachel preferred to be upright when she pooped. Still gripping the front of the diaper's waistband, she looked at Rachel's scrunched up face, then back at the massive diaper, which was apparently about to grow even more. Thinking quickly, she decided she had no choice but to tape up the diaper and let Rachel go again before she changed her. After securing the tapes back in place, she stepped over her sister's abdomen and grabbed her by her hands. "Come on, let's get this over with..." She pulled, but found it a lot more difficult to get Rachel to an upright position thanks to the added obstacle of the mound strapped to her behind. "Hngg... Hya!" With a hefty tug, she managed to mobilize the small girl. Holly's feet couldn't spread wide enough though, and as she stepped backward, she found herself getting caught against the squishy mound. "Ack-!" Still grabbing Rachel's hands, she stumbled to her butt, landing with her crotch squarely in front of the drooping diaper. Luckily, this was just the extra bit of force she'd needed to pull the girl to a standing position, her diaper drooping dangerously low beneath her knees.

Another gurgle rang out, just as loud as before. Rachel again doubled over. "Nnnngggh... Gotta...!"

PBBRRRRRRRRBLBB

A loud, gurgly fart, and the floodgates were opened. As Rachel bore down with all her might, her diaper once again started expanding to accommodate the accumulating mess within. Holly could only watch in awe as before her, the diaper expanded to cartoonishly large proportions. It dropped down well past her knees, and then to her feet.

"Hnnngh! Mmm... Mnnnngh!!"

Rachel made fists and strained hard as more farts, gurgles and crackles rang out from beneath her, her padding expanding with each passing moment. The padding at last reached the floor, forcing it to flatten and spread forward and backward, starting to engulf the girl's legs slightly. Rachel's legs were still straddling the diaper, and she felt the sides begin to graze her calves and between her thighs. This contact snapped her back to reality, and as the outer edge of the diaper was reaching her crotch, she managed to scutter backwards on her hands and feet away from the growing monstrosity. Jesus, when will it end?! she thought. She had figured Rachel could only have so much poop left in that little body of hers, but this was beyond reasoning!

"Hnngh... Ahhhh..."

At last, Rachel gave one final fart, and her third mess had come to an end. Holly could only gawk: the padding was now stained thoroughly brown and stretched forward and backward at least two feet in each direction. Her legs were barely visible as the diaper had all but swallowed them. The tapes at her waist seemed to be hanging on for dear life against the strain, and there wasn't a single wrinkle left on the outer plastic: the diaper simply had no room to spare.
