“A Rare Opportunity”
For what felt like the fiftieth time, Rarity checked the door to her shop. Locked. Opal occupied with catnip? Check. Making sure the sign in the window did indeed read “closed,” the white unicorn breathed a sigh of relief. She was really, truly, alone. Giddily, she retreated to her own room, locking the door to that as an extra precaution. With a nervous giggle she opened her dresser and dug deep into the back, eventually pulling out a thick, white garment: a cloth diaper. The indigo-maned pony felt a bit guilty as she folded the diaper around her abdomen and securely pinned it (using custom-made pins shaped like her cutie mark, of course). The garment did feel wonderful: warm, thick, fluffy, snug. However, the fashionista had to admit this was very much a guilty pleasure. A full-grown mare, wearing diapers at her age? And one so refined as her, no less! Rarity couldn’t explain just why she liked it; for as long as she could remember, she for some reason had a fascination with the absorbent underpants. Perhaps she was toilet-trained too early? Maybe she simply wanted a piece of her childhood back?
She shook her head. Perhaps she’d never figure it out. Regardless, the mare enjoyed this, even if she was embarrassed by it. The unicorn went back to the drawer and retrieved a waterproof diaper cover and put it on over her padded bottom, taking care to thread the laces and tie the thing securely. The cover was a light blue, with indigo trim, being secured with a string that was also indigo. The unicorn sat on her bed and brought her hind legs together, enjoying the soft bulk between them. She got up and paced around the room, delighting in the feel of the diaper. It was so soft, so comfortable. It made her feel like a foal again, waddling around in the thick garment.
Now Rarity stood where she was—in the center of the room—and let her breath out nervously, her heartbeat starting to quicken. This was it, the moment she had waited all day for. She spread her legs apart, then hesitated. Was she really going to do this? She normally hated getting the slightest bit dirty, and peeing herself would certainly not leave her clean. On the other hoof, she did enjoy the warmth and moisture of a wet diaper, along with the naughty thrill it brought…
The mare stood back up. Perhaps she’d wait after all…Then again, though it was tempting to just wear the diaper and use it while she made her dresses, she couldn’t work like this; it would be too distracting to her artistic vision. She would just have to use it here. She shook her head, then squatted again. She didn’t get free time too often, not with all the dress orders coming in as of late. Add in the almost constant threat of having to babysit her little sister, Sweetie Belle, and it was all too clear she shouldn’t squander an opportunity like this to unwind.
The white pony relaxed her bladder, and pushed. Her face flushed with both embarrassment and excitement as she felt her privates become wet, the fabric between her legs growing warm and heavy as it soaked up her urine. It was a bit hard to hear, but to the trained ear like Rarity’s, a muffled hissing sound was audible. She felt so naughty doing this! It felt so bad…but at the same time, it felt so good! There was a certain thrill to the whole affair, of doing something so vulgar yet so satisfying. The unicorn had to admit, this was some pretty effective stress relief. Rarity was disappointed when her stream began to die down; she pushed a bit more in the hopes of keeping things going a little while longer. Delighted that her efforts yielded a spurt of urine, she pushed again. Another spurt; she guessed her bladder wasn’t quite empty after all.
With the next push, the fashion expert felt something else move. Her already pale face blanched as she realized she had pushed too hard, and now her diaper felt very warm and heavy in the back. She nearly fainted right there, but somehow she managed to retain consciousness. How could she end up doing something like this? She didn’t mean to mess in the garment! Peeing was one thing, but defecating? That was certainly taking things too far. Now, not only was she wet, but she was also sitting in…in…pure filth! Any enjoyment the pony was getting from her strange hobby was certainly gone by now. How could things possibly get any worse?
A white unicorn filly with curly pink-and-purple hair sat up in her bed and blearily rubbed her eyes. “Big Sis, what are you doing?”
