~The Chapter~
Twilight's bathroom door burst open and a groaning Sunset stormed inside, slamming the door shut behind her before waddling urgently towards the toilet.
"C-come on, almost there!" She begged, wincing as she was assaulted by another powerful cramp.
*Pwwfpt! Pwffffprt!*
Yanking the lid up as wet farts sputtered from her rear, she glanced down into the unsuspecting toilet bowl. She quickly turned and yanked down her jeans and panties in one swift motion, a wet stripe of brown smeared over the inside. The moment her cheeks hit the toilet seat, immediately a massive landslide of liquid shit shot out of her. Her bowels began loudly emptying themselves as putrid smells and sounds filled the small room.
*Splrptprt!*
Sunset gasped as her asshole stung from hot diarrhea that was pouring out of her, knuckles white as she gripped the bathroom counter with her right hand. Face twisted in a pained scowl, she glanced down fearfully between her tensed thighs. What she could see of the toilet bowl had already been turned a deep brown color as it only continued to fill with more and more of her mostly liquid waste.
"Dammit, Trixie!" She growled, well aware of the root cause of her current debacle...
"Come on Sunset! Just a little nibble!" Trixie begged, holding out her fork towards Sunset's strained lips.
"Trixie, I already told you, I am not eating that," Sunset replied in a sharp whisper, trying not to draw the attention of any of the other people in the restaurant.
But Trixie continued to waggle the impaled meatball at the end of her fork, taunting her with it. Spaghetti sauce oozed down the utensil, coating a few stray noodles that were caught around the metal prongs. Sunset just glared back at her friend, Trixie's puppy dog eyes tearing away at her heartstrings despite Sunset's defiance.
'You know you want it.' A voice spoke in Sunset's head. She ignored it.
"Trixie, you know as well as I do that stuff gives me indigestion. I'm going to Twilight's for a sleepover tonight and I don't want to deal with that."
"Oh come on! It's just one meatball! You've never even had one before! And after all, the Great and Powerful Trixie eats them all the time!" Trixie argued.
"Yea, but you didn't live your whole life eating nothing but hay, fruits, and vegetables."
'And the occasional cooked fish... or ten...' The voice in Sunset's head was quick to remind her.
"Pleeease? Just one itsy bitsy bite? For me?" Trixie begged, pouting her lips in an adorable fashion.
It was getting harder and harder to not stare longingly at the succulent ball of well-cooked meat that hung inches away from her mouth. Though her stomach growled for it, she knew all too well what would happen if she indulged again...
'Just do it, you'll be fine!' The devious voice in her head spoke yet again.
Sunset let out a long sigh, rolling her eyes.
"Fine..."
About two full course meals later, most of which purely consisted of various meats and sauces, and here was the consequence of her indulgence.
Sunset was ripped from her thoughts as the last of the hot magma leaked from her anus, her intense bowel movement finally transitioning to a smushy mess of slender logs which slithered out of her. At this point, she dared not glance down into the bowel again, terrified to see what kind of damage she might have already done.
Every time she ate meat since coming to this world, she would always be due for a messy trip to the bathroom not long after. She still had no idea how Trixie managed to convince her to eat as much as she had by the time they finally left the restaurant. Yet, as always, Sunset foolishly hoped that the inevitable wouldn't strike while at Twilight's place tonight.
Though, even as she felt the hot stinging at her rear, another sensation had also started to take root in the vicinity. One that tinged even more as she felt her asshole being spread apart by each warm and squishy log. As much as she hated to admit it, she this was her favorite part of eating meat.
*Phtcchkt*
"F-fuck~" Sunset gasped, feeling a particularly thick log push through her asshole, the tingling sensation in her clit intensifying.
Unable to resist the temptation any longer, she dove her left hand down, pressing her fings firmly against her already quite wet pussy. The horrible smell was intoxicating, driving her desires higher and higher. Mere inches away from her fingertips her ass continued to push out long thick turds which were piling higher and higher beneath her.
A moan almost forced itself from her mouth when there was a sudden knock at the bathroom door. Sunset instinctively clenched, pinching into a particularly thick log that sent a sharp shiver running up her spine.
"Um, Sunset, are you okay in there?" Twilight called, sounding deeply concerned.
*Frrprpt!*
"U-uh, y-yea, I'm... fine," Sunset replied, voice wavering as she combated the burning pressure and tingling from below.
"Well, just let me know if you need anything..."
Sunset waited with held breath as Twilight left, her footsteps growing distant as she returned to her bedroom where they had been hanging out earlier.
As soon as she was gone, Sunset gasped, releasing yet another flood of mushy shit the moment she relaxed her anus. The feeling finally wore away the last of her restraint, her hand rapidly stroking her needy slit.
"W-why does this have to feel so -Ah~!- good!" Sunset moaned as quietly as she could, leg muscles tensing as yet another thick turd slipped through her asshole.
She prayed that Twilight wouldn't hear her lustful moans, though she continued rubbing faster and faster. Her pussy burned with a desire almost as intense as the sting from her anus which only added more fuel to the bonfire.
The final straw came as the flow of mush suddenly stopped, a massive and hard turd plugging her anus. Pushing out, her asshole struggled to stretch wide enough to allow it's passage. At the same time, Sunset plunged two whole fingers deep into her pussy, setting off an avalanche of pleasure that rippled and intensified throughout her entire body.
"A-ahahaa~" She trembled, legs convulsing as she finally came, her asshole finally widening enough to allow the final massive turd to fall out of her.
The last of her intense bowel movement squirted out of her worn and filthy anus as Sunset breathed heavily, riding the pleasure high as she went limp on the toilet seat.
"S-such a d-dirty girl~" She moaned in a whisper, the pungent smell finally causing her nose cringe.
Sitting up slowly, she dreaded looking down into the toilet bowl beneath her, already surprised the pile hadn't reached up to her messy cheeks yet. One thing was for sure, her ass felt utterly caked with layers of brown shit. Cleanup was not going to be easy. Not to mention, she had most certainly clogged the toilet. Twilight's toilet...
With a sigh, Sunset turned and reached for some toilet paper...
Only to find an empty roll...
"Oh shit."
