SexTheHex's Smut

--------

So backed up; Olivia found even sitting down difficult. 

Just the simple act of arching her back and bending her knees proved enough locomotion to goad the bratty shit in her abdomen. Its dull, thick head came rubbing against her prostate, angry, ready to punish for her insolent movement. The mere act of sitting had turned to anal sex with her own shit.

Olivia fiddled with her laptop plugged into the display monitors, trying to make sense of her emails, trying even harder to focus on anything but the raw volume of need stemming from her ass. By the moment her outrageous shit crushed more of her attention span and her p-spot right in tow with its weight and heft. Just this rubbing had her terribly erect below her office mini skirt, panties tenting in the front from all the foreplay with her colon. Much longer with this sensation and the back would be tented too.

It really was unfair. Sure, Olivia's odd job here had her testing all sorts of weird sexual matters, shoving herself against dicks, touching them, snorting them... Though she still couldn't fuck them! It'd been commonplace for these monstrous cocks to throttle Olivia's backside, but the new HR department feared any more ass pregnancies might land the company in hot water. Thus, Olivia was left alone, simmering in withdrawal, replacing her old outlet with kinky hybrid aphrodisiac-constipation pills packing her ass to capacity.

A voice suddenly popped up.

"Olivia, did you end up sending that email to marketing?"

Olivia's mouth began to move for normal human conversation with her coworker Mindy, but the raw need from her manhandled prostate repurposed her open mouth.

"OoOoOhH..." Olivia moaned.

A few seconds stirring in awkward silence and Olivia snapped back to real life, red in the face.

"Yes, yes of course I got all the reviews out. Double check your inbox for the forward I guess? Outlook is such a dogshit program it's probably hidden somewhere."

Mindy looked on at the sweating, struggling Olivia, both of her hands now clamped around her ass cheeks.

"Olivia do you um... Do you need to use the restroom?" 

"Y-yeah..." Olivia admitted. "B-but I can't! I get so fucking wound up all day and yet I can't take a cock up my ass at all! I need something in there. A g-gigantic shit clogged up my ass i-is the only way I can-"

Olivia went still, blank in the face, ass cheeks wobbling and clenching in her purple panties. A very tiny crackle began, and Olivia's face looked as bashful as when her girlfriend called her a pretty princess. A thick, blunt turtle head spread out her ass and prodded the silk of her panties.

"Olivia, are you pooping!? Like right here!?" 

"H-huh!?"

Olivia snapped back from her shit-enduced fantasies, and the obese head of shit dying to drop out her fat ass retracted back inside.

"Girl, go to the bathroom! I don't want to have to smell that all day in here!" 

Oliva groaned.

"Look, I'll deal with it, okay?" 

Mindy looked her up and down, then simply moved along. 

Olivia tried to get back to her emails, but the inevitable couldn't be ignored. Mindy was right; Olivia did need to get to a bathroom as soon as possible, or else she risked shitting herself right in the middle of her cubicle. Best to deal with her splitting shithole as soon as possible. Olivia stood up and-

Her gut roared! 

“GRRGGGNNNNLLL!”

"Fuck! FUCK!"

Too fast, too violent! The powerful dump inside her didn't like being whisked around so freely. Sudden movements were agitating, and the giant heap of matter inside her took its revenge with glee. The impulse to push suddenly hit, and took over everything in that poor woman.

Olivia panicked. 

"Huh? No, no, no-no-no-NO!" 

For a moment it really did feel as if all that matter that'd been throttling her prostate just from walking this morning was bound to spill out. Time for her shit-birth then. At least she’d feel some well-deserved relief…

That is, until the descent of her livestock-sized shit slowed as it prodded into her panties, and suddenly the orchestra of muscle movements in her ass simply stopped. 

This wouldn't be a nice, begrudgingly accepted accident where Olivia quickly let a turd drop into her panties and waddled to the bathroom. No, Olivia's shit wanted her to suffer.

Olivia barely perceived her legs growing unresponsive, and her gaze dropping lower. Only when she tried another step forward to get to the damn restroom did she notice herself bending into a deep squat, her body so desperate to purge her of this burden it had to assume the ideal position for cutting a shit; at least from the mind of her greedy prostate. It certainly did well to show any coworkers just how big her butt had gotten, stuck out nice and far, something like a third ass cheek blooming in her underwear from the burgeoning turd. Farts spilled out of her now that she stood so vulnerable. The budding turtle head throttled forward even more, like an inevitable glacier.

"Oh my god, oh my god it's-"

Olivia's further panic died in her throat. Her ass demanded as much power as possible to shove out this behemoth; that other, lesser end of her with a mouth didn't matter right now. It was left to twitch and writhe, with her lips in a big orgasmic O, while her ass flexed, and stretched, and farted, trying to give birth to this titanic thing.

"I can't move! I-I can't m-mooo" A dumb sentence or two from Olivia, before she went right back down to huffing down air and straining.

Her huge ass flexed truly terribly wide now. The blunt, stoney, wide head of two weeks of drug-enhanced dumb designed to taunt needy perverts like her kept spearing her open. Every moment she pushed, more of the rocky, bumpy texture pressed into her p-spot, and punished that abused cock muscle for all it was worth.

And that was just pushing. There had to be times where Olivia withdrew and took in another sharp breath, and with that, the stubborn dump receded, and dragged its heft across her that sex bit in her ass until she shivered with joy. Pre dribbled freely from her well-milked panty-clad cock. Erect nipples pushed against her nice office blouse. Olivia scarcely paid attention to onlookers as remarks like "What is she doing!?" and "Oh my god, Olivia's shitting herself!" Grew thicker.

One last retraction of that dump, a mighty one. Something was loose. Something finally had given way.

Olivia pushed with all of her might!

"NNNNNNNNNGGGGGGGH!" 

"POOOPING! I-I'M POOOOOPIIIIIING!"

In a split second, her ass stretched right back to that insane diameter, roaring with farts, spreading wide! That crowning mass pushed her panties out a good two inches, then three, then too far to ever retract, an official public accident in her panties! 

The fat inaugual turd shot out with force, like it was nothing, like it wasn't the thickest pseudo-dildo custom built for her own greedy rear to ever sodomize Olivia. It throttled out effortlessly, easier than it ever should, the rapid thrust of endless contact dragging against her prostate sending her sputtering to handsfree anal orgasm. The front of her panties went wet with white as she sullied them completely; naughty stains in the front, an apocalyptic mountain of ass thundering into the back.

Olivia looked up to the buzzing lights above, too weak to scream in joy, drooling like an idiot onto her breasts as the orgasmic high of her life came from her own shit.

That unbroken column of unreal thick shit, driven by drugs for kinky pleasure, finally started bending after a freakishly long distention of her underwear. It coiled like a grand python, ballooning her white panties, sagging everything under their immense weight, and staining material effortlessly as a dump like a cow’s thundered out of this cute office woman. 

Immediately the sag told the imminent tale of what would happen if it kept dropping at this rate. Olivia’s dump would soon conquer her waistband and leg holes, and come spilling onto the carpet. Mindy felt some pity for Olivia, and got a trash can ready below her ass for when the inevitable happened.

Still it kept extruding. Still Olivia kept unloading. A full fucking manure bag’s worth of her filth unloaded from her body enraptured in orgasm as every moment of pushing and dumping maintained the orgasmic high of her life. The waistband of her panties snapped asunder, and now Olivia defecated directly into her own wastebasket, the thing already in danger of overflowing. 

After a long, drawn out, minutes-long display of Olivia unloading all her shame, she finally gasped for air, sweating, anus left completely agape.

She looked around at her coworkers.
