Nora Valkyrie, as you all probably know, is a hyper teenage girl training at beacon academy to be a huntress. As hyper as she is, she is full of many secrets. One of them being she enjoys pooping and peeing her pants, both for fun and when she needs to go. She uses a new semblance to hide the smell and sound of her peeing, pooping and farting when in public, but when shes alone, she doesn't hold back. She wears special diapers that are more comfortable, will never leak, can hold an 18 wheel dump truck worth of poop, and will expand as it is filled. The diaper is also designed to only puff out and not sag, which is helpful. Nora is also naturally immune to diaper rash, and she is very strong, so the weight of the diaper is not an issue, nor will it be. Lucky her.
Nora was waking up one morning, when before she even thought about anything else, she was hit with the sudden need to poop and pee. Lucky her, she was wearing her diaper. She grunted and pushed, farting, and then a massive pile of mushy poop fell into the diaper with a rather loud "squish". Nora was naked with nothing on but the diaper. She then started to wet the diaper, with a loud "hissssssssssssss," and she pushed yet another mushy load into the diaper with a loud "squish."
Nora found herself aroused by this, and started to masturbate, having finished wetting her diaper. However, she continued to put load after massive mushy load into the diaper, causing it to expand to 1-1/2 feet in diameter, and she found herself 1 foot off the ground from all the poop that already filled her diaper. She inhaled deeply, enjoying the stink. She cut a rather long, wet, stinky fart, followed by a mushy pile. She squeezed the diaper wither her free hand, and was amazed at the size, as the diaper continued to fill, and as sh rose up further from the immense volume of poop that filled her diaper. "Maybe I'll switch to my pretty pink panties next and mess them with Pyrrha while I sit on her face, and after I've had my tall glass of choco-lax laxative milk," she said to herself, getting very wet at the very idea of doing so.
Nora found herself nearing an orgasm, and her butt erupted with one last massive torrent of mushy piles of poop, which lasted about 2 minutes, causing the diaper to rapidly expand to 2-3/4 feet in diameter, and Nora was 3 feet off the ground from all the stinky poop in her diaper. Nora then orgasmed hard, and she panted. "That was so fun! I can't wait to play with Pyrrha next," she exclaimed loudly.
