(Woman to Hippo)



Fiona let out the first yawn while in her workplace. Immediately after clasping her lips, she knew that something was off. There was almost a flabbiness to the way Fiona’s face now sat on her bones, as though her mouth had stretched wider in the process of yawning. She was able to shrug all of this off, however, and turned back to her work only to be distracted soon after in a less ignorable way.



As pressure began to slowly build in her bowels and push against her rectal walls, Fiona realized she was on the verge of farting. She clenched her buttocks in time for it to stay in her body, thankfully, but the thought of how embarrassed she'd be if her coworkers heard her break wind made Fiona too nervous to try to ease the flatulence out of herself subtly. She instead just spent the next several hours shifting uncomfortably in her seat as to retain her dignity, although it did mean she had to listen to her chair creak from the slightest movement as if strained from her weight

The second yawn came at lunchtime. This time, the distance between her parted jaws was very clearly greater than before. Fiona’s nostrils were much larger as well, their size making for inhuman flaring of her nose. Her fingers moved more stiffly, and she soon found she could barely hold a salad fork anymore without using both hands — her motor control had worsened, somehow! People around Fiona took notice of the difficulty she was having but said nothing, even when she forwent the silverware altogether and simply ate out of the salad tub with her mouth.





Yet for some reason, Fiona found none of it embarrassing. She even rethought her stance on farting in front of everyone. Everyone farts from time to time, why shouldn't she at least be open about it? The pressure had been

continually building all morning — never waning in its urgency — and Fiona couldn't justify holding it in any longer. She relaxed her sphincter muscles, anxious about what was to come next.

Fiona was about halfway home when she yawned for the third time. As she did so, she could feel the skin of her cheeks physically stretch to beyond their natural limit to allow for a wider opening of the mouth than ordinarily possible. The strain of stretching process on her face squeezed Fiona's eyes slightly out of their sockets, making them bulge noticeably out to the left and right of her increasingly broadening nose.



Her mind drifted back to the incident in the office. Fiona didn't think what she did should be so taboo! In fact, when the overpowering urge to fart returned, she suddenly didn't have even the slightest compulsion to stop it rocketing through her system and even found herself subconsciously relaxing her butt cheeks as to produce the most pronounced sound possible. Fiona felt a rumble in her bowels and let it rip!



PPPFFFFFFFFTTTTT!



An explosive load of gas was forced out of Fiona's anus and into the vehicle, the resulting stench facing no difficulty in permeating her nose due to her nostrils' larger size. The smell, to her utter disbelief, was actually refreshing! It was a complex scent, and something about its precise odor made it distinctly... hers. Fiona felt a rush of euphoria flood into her skull after inhaling more and more of the air around her, basking in how disgustingly right it felt settling on her tongue. Feeling entirely better about letting out an occasional bamp or toot along the way, Fiona continued home.

Her neighborhood had just begun to crest the horizon when she yawned again. Fiona's mouth opened to an even larger extent, further loosening the skin on her cheek and pushing her jaw out a slight ways from the rest of her face. She looked to her side-view mirror in time to see her canines coat themselves in ivory before swelling to double their normal size. Too entranced by her teeth to notice the clumps of hair beginning to fall from her head, Fiona also found herself idly grinding her new chompers together out of some inner need to do so.



Eventually deciding to stop and get some food, the deafening growl of her gut made Fiona realize just how hungry she was. Despite having eaten an entire meal during her lunch break back at the office, Fiona was already ravenous for another meal not half an hour after the last! The lustful desire for food that she had soon ebbed away any worries about her suddenly-leathery skin or stumpier arms and legs. The primal drive to eat brought Fiona to a Salad Shop, whereat she parked her car and stepped onto the sidewalk.



She found that her gait possessed an inexplicable unsteadiness, and it was after looking down that she realized her feet had swelled in size and even burst through her heels. On top of that, her five, once-gorgeously painted toes had merged and hardened into four, thick ungulate nails. Fiona found the oddity strangely... normal, as though it was odd to question what was happening. Never one to distrust her gut, she refocused on her unsated appetite and stopped worrying about her clothing, not even caring to tighten her leggings so that her buttcrack wasn't more than half-exposed to the world. Absentmindedly scratching her asscheeks, Fiona wobbled her way into the Salad Shop.

It was upon Fiona yawning for a fifth time that her mental faculties began to falter. After opening her jaws in a nearly-90° arc, she allowed the exhalation that followed to assault the face of an employee at point-blank range with no ashamedness. The young boy behind the cash register nearly passed out at the smell of her putrid breath, but Fiona merely giggled at the scene — the smell wasn't bad at all! Fiona's nose pushed further forward from her face and her teeth further back in her mouth, making her head far more elongated than it was before and giving her the beginnings of a snout.



Once people started to point at her, however, Fiona knew she needed an escape plan. She grasped the multiple boxes of salad she'd purchased and carried a rumble through her chest until releasing it out of her massive maw.



BRRRAAAAAAAPPP!



The belch had enough power (and stench) behind it to break up the crowd that had formed around her. Fiona took the opportunity to stumble toward the door and traverse the distance to her car. Just as people in the Salad Shop began running out the door, Fiona floored the gas pedal and drove away.



Success!



Fiona hurried home as a dribble of saliva dripped from her muzzle in excitement for the eight-salad meal that lay in store.

Finally sat on her sofa at in her house, the sixth yawn to escape from Fiona's rubbery lips was the first one to make an obtuse angle with her jaw. Her nose further pulled away from her face in order to merge with her lips, leaving Fiona with a snout whose top and bottom parts were essentially the only flesh past her eyes — her head was mostly mouth at this point. Fiona's nostrils soon became larger than her eyes and made her heave steamily and loudly through the rise and fall of her enormous chest.



Fiona progressively accumulated more fat as the feast went on, and befitting folds of flesh formed across her body as result. Through shoveling handful after handful into her muzzle, Fiona could tell when an aspect about her mouth changed. She immediately felt when her tongue grew to the length of her snout, and she knew the exact instant her canines and incisors spanned a higher vertical height than her mouth.







Soon, Fiona ate enough food for the couch to groan underneath her weight, eventually giving out and leaving her to lick up scattered leaves from the floor around her. Even still, as she unconsciously scratched her crotch in satisfaction of her meal, she needed more. More food. More plants. And there was only one place to get them: outside >< —><—><—><—> • <—><—><—><—>< It was upon Fiona yawning for a fifth time that her mental faculties began to falter.

As she exited her front door, the force of yet another yawn forced Fiona into a quadrupedal stance as her mouth somehow found more volume to occupy in her head and bristles sprouted at the end of Fiona's snout. While leathery ridges took formation over her eyeballs, ensuring she'd forever see like a non-predator, a tail forcefully ripped itself out from her rear end and swished about in the breeze.



Fiona made a start toward some swamplands she could smell in the distance only to stop and stare at the ground. Of course! The grass! The realization of how big a feast she was in elicited a roar of delight from Fiona and she bent down to eat the vibrant vegetation under her cloven hooves. Meadows like the one she was in had extremely short grass, so the size of her snout and tusks made it impossible for Fiona not to pick up some dirt in each and every bit.



Still, she found it nonetheless worthwhile to chew through the mouthfuls of sod just for the succulent blades of grass she craved more than anything. Even if the occasional worm was crushed by her jaws, Fiona truly didn't mind.

She yawned once more, this time thanks to an instinctual need to communicate where exactly she'd designated her feeding area. The insides of Fiona's mouth moistened themselves with saliva, and her tongue became incredibly girthy as Fiona swished it around her mouth to pick scraps of food out of her gums.



Fiona's teeth also grew to be more exaggerated as she ate, her frontmost teeth turning a brownish-yellow and becoming hideously overgrown. The familiar feeling of gas rising up her windpipe caused her neck and throat to thicken considerably, and the burp that exited Fiona's jaws sent with it a rumble that made her jowls flabbier still.



Minutes of blissful grazing turned to hours as the evening light led Fiona into wooded marshlands in seek of shelter for the night. She felt instantly at home in the shaded willow trees and knew it was her new territory right away.

Just as Fiona let out a declarative yawn for territorial dominance, her physical changes completed themselves. Her snout widened near the tip to give her tusks a firmer purchase in her jaws. Every inch of Fiona's body now reeked of hippopotamus musk and filth , and she was able to fully appreciate the odor's intensity with her enhanced sense of smell.



Upon feeling the urge to pee, Fiona was far enough gone to simply let the stream of urine flow freely out from beneath her undercarriage, not caring when most of it splashed on her leg. These were her grounds, and she was going to make her scent known no matter what; no other creature dare stray close to her territory!



She was the most feared hippo in the land!

With a final, bestial yawn of authority, all humanity faded from Fiona as her maw opened in a 180°-angle to unleash a roar across the landscape. The hippo slunk into a nearby pool of mud and happily wallowed in the filth, content exactly as it was. It found the smell of the swamp to be inviting and the swamp her predestined place within it. Nothing more than an animal, it bathed and wallowed in the mud until, at long last, it felt content with itself

It was louder than she could have imagined, and a room full of people instantly turned to look at her in unison. She sheepishly apologized and gathered her things while her co-workers watched with concern. As she closed the room's door to leave, though, all she could think about how relieving it had been to fart like that.
