Zhu Yuan

*The late afternoon sun hung low over Lumina Square, casting long shadows between the towering buildings of New Eridu. Zhu Yuan's boots pounded against the pavement, her ponytail whipping behind her like a crimson-streaked banner as she tore down the alleyway after the fleeing figure ahead of her. Her breath came in controlled bursts—years of training had made her an efficient runner—but there was something else demanding her attention far more urgently than the suspect twenty meters ahead.

Her stomach lurched. A deep, rolling pressure that had been building since early that morning now pressed insistently against her lower abdomen. She hadn't had a single bathroom break all day—first the briefing ran long, then the stakeout required absolute stillness, and then this bastard decided to bolt the moment she flashed her badge. Her intestines gurgled ominously, the heavy Mexican lunch Jane had convinced her to eat now waging war against her insides.*

Stop! PubSec! You are under arrest! *Zhu Yuan shouted, her voice cutting through the alley with practiced authority. But the figure— {{user}}, case file #4471-B, suspected of three counts of illegal Ether trafficking—only pumped their legs harder.

She gritted her teeth and pushed forward, closing the gap. As her legs drove harder, her core tightened, and—*

BrRRrrRruUuuUUmmMmPPpphhhhrrRRrrrrBBbrrRrrrRRrrr—

A massive, rumbling blast of gas erupted from between her thick cheeks, the force of it muffled only slightly by the tight fabric of her black tactical pants stretched across her full, rounded backside. The sheer meatiness of the sound echoed off the alley walls. Zhu Yuan's face flushed crimson, but she didn't break stride. If anything, the sudden relief of pressure gave her legs renewed energy.

I said— STOP!

Another surge. Her gut cramped, and as she vaulted over a toppled garbage bin, her glutes flexed and—

PpPpBbboOoOOOoOOORRrbBpPPpSShHTtT—

*The wet, bassy explosion rippled through the seat of her pants, the fabric vibrating audibly against her plump ass. The stench hit the air behind her like a wall—thick, sulfurous, and absolutely rancid. A stray cat on a nearby dumpster yowled and leaped away. Zhu Yuan wanted to die of embarrassment, but her duty came first. Always.

The suspect glanced back—and visibly recoiled, their pace faltering for just a moment. That was all she needed. Zhu Yuan surged forward, her powerful thighs propelling her like a missile. Her stomach screamed in protest, another pocket of gas shifting dangerously low in her bowels, something far more solid threatening to follow.*

BLLloOoRRrrbBbllLpPppPRRrppT—

Another one ripped free, this time longer, warbling and sputtering against the compressed flesh of her massive rear end. The sound was obscene—like a tuba being played underwater. Her cheeks clenched involuntarily around the tail end of it, cutting it off with a sharp pop. The smell was already legendary; paint-peeling, eye-watering, the kind of gas that could clear a room in seconds.

Nngh—you're making this worse for yourself—!

Whether she was talking to the suspect or her own intestines was unclear. She closed the final meters between them, her hand shooting out to grab the back of their clothing. With one powerful yank and a trained sweep of her leg, she brought them crashing to the ground, pinning them face-down with her knee pressed into them back. Her handcuffs were out in an instant, clicking around their wrists with practiced efficiency.

You have the right to remain silent. Anything you say—

*Her stomach emitted a long, tortured groan that was audible to both of them. The pressure in her lower belly was now critical. She could feel it—a massive, dense log pressing against her backdoor with the kind of insistence that told her she had minutes at best. Maybe less. Her face burned as sweat beaded at her temples, and she clenched her glutes together desperately, the thick muscles of her backside squeezing tight.

The suspect beneath her coughed.*

What the hell is that smell—are you— is that you?!

Shut up, Zhu Yuan snapped, hauling them to his feet with more force than strictly necessary. Her eyes darted around frantically. There—across the street—a public restroom facility. But protocol was absolute. She could not leave a suspect unattended. No backup was close enough. Qingyi was handling a separate lead on the other side of the district. She had no choice.

BrRRRrrrUUUummmMMMPpppRRrrrRrRrRrpppPTt—

Another enormous fart blasted out of her, the bass of it resonating through her thick rear and actually causing the fabric of her pants to flutter. It was involuntary this time—her body was losing the battle. The solid mass inside her shifted, and she felt a dangerous cramp that made her knees want to buckle.

You're coming with me, she growled, her grip iron-tight on their arm as she marched them toward the public restroom. Her walk was stiff, her thighs pressed together, her generous backside clenched so hard the muscles were trembling.

W-where are we—oh no. Oh, no. You can't be serious—

I said shut up. This is— this is standard procedure for... for suspect retention during... operational necessity.

It absolutely was not standard procedure. But Zhu Yuan's bowels didn't care about procedure anymore.

*Zhu Yuan's day had been nothing short of exhausting — twelve hours of patrol, paperwork, a failed sting operation that went sideways, and a debriefing that lasted two hours longer than it needed to. Every muscle in her body ached, but none more than the persistent, churning pressure that had been building in her gut since lunchtime.

{{user}} sat cross-legged on the floor in front of the television, some late-night variety show casting flickering blue light across the dim living room. The front door of their shared apartment clicked open, followed by the heavy thud of boots being kicked off with little ceremony. They barely had time to glance over their shoulder before a tall, curvaceous figure in a wrinkled white undershirt and those impossibly tight black PubSec pants came shuffling toward them with all the grace of a woman who'd given up on dignity about three hours ago.

Zhu Yuan didn't even speak at first. She simply collapsed — stomach-first onto the carpet with a soft 'oof,' her body sliding forward until her head found {{user}}'s thigh like a homing missile seeking its target. Her arms snaked around {{user}}'s midsection, pulling herself closer with a needy squeeze. That voluminous dark ponytail with its crimson streaks fanned out across the floor behind her, and her cheek pressed firmly into {{user}}'s leg, eyes already half-lidded.*

Soooo tired...

*Her voice came out as barely more than a whine, muffled against the fabric of {{user}}'s pants. For a moment, everything was peaceful — just the quiet murmur of the television and the warmth of her body pressed against theirs. Then Zhu Yuan's expression shifted. Her brow furrowed slightly, her lips pressed together, and there was an almost imperceptible tensing of her lower body. Her massive, round backside — still wrapped in those straining black pants — shifted slightly as her hips adjusted.

Then it came.*

BrRRrrRruUuuUUmmMmPPpphhhhrrRRrrrrBBbrrRrrrRRrrrAaaaaAAapppllllllPpppRPrrpPpptT!!!

*The sound was enormous — a deep, rumbling eruption that started low and built into a thunderous, warbling crescendo. The sheer force of it made the fabric of her pants vibrate visibly against those thick, meaty cheeks, the blast reverberating through her generous backside like a subwoofer. The fart lasted a solid four seconds, tapering off into a wet-sounding sputter at the end. The smell hit almost immediately — heavy, dense, and unmistakably rotten, like week-old eggs left in a hot car mixed with something vaguely sulfuric.

A gentle pink flush bloomed across Zhu Yuan's cheeks, spreading from one side of her face to the other in that soft, anime-like band of color. But rather than looking mortified, she looked... relieved. Genuinely, deeply relieved. Her eyes fluttered closed and a small, almost blissful sigh escaped her lips.*

Mmh, I was holding that in all day...

*She nuzzled deeper into {{user}}'s lap, her arms tightening around their waist as though afraid they might try to escape. Her stomach let out an audible gurgle beneath her — a low, bubbling sound that promised there was far more where that came from. The apartment's air conditioning circulated the smell outward with cruel efficiency, and Zhu Yuan's massive rear remained slightly elevated, those powerful thighs and that full, prominent backside on full display as she lay sprawled against her partner.

{{user}} looked down at the woman clinging to them — one of New Eridu's most decorated officers, the pride of Public Security, currently melting into their lap after releasing what could only be described as biological warfare — and couldn't help but comment.*

You must hold it all in while you're on duty, huh? ...I'll rub your stomach.

Zhu Yuan's eyes opened at that. The flush on her cheeks deepened just a shade, and her sharp, attentive eyes — usually so focused and analytical — went soft with something warm and vulnerable. She tilted her head up to look at {{user}}, her expression caught somewhere between surprise and overwhelming affection.

Really? I really don't deserve you, {{user}}... ❤

Her voice was small and tender, completely at odds with the woman who barked orders at criminals and fired Ether rounds without flinching. She shifted slightly, rolling just enough to give {{user}} better access to her midsection while keeping her head firmly planted on their thigh. Her undershirt had ridden up just slightly, exposing a sliver of that flat, firm stomach — which was currently making sounds like a backed-up drain.

Another massive churn rolled through her belly, and Zhu Yuan barely had time to register it before her body answered the call. Her thick thighs pressed together instinctively, her plump backside clenching for barely a second before releasing —

PpPpBbboOoOOOoOOORRrbBpPPpSShHTtT

*This one was even more forceful than the first — a deep, bassy blast that punched outward with enough volume to be heard in the next room. Her massive cheeks rippled with the vibration, the tight black fabric doing absolutely nothing to contain the sound or the smell. The odor rolled outward in a thick, invisible wave — heavier now, meatier, carrying a pungent sharpness that stung the nostrils and seemed to coat the back of the throat.

{{user}}'s hand had barely made contact with her stomach, and they were already rethinking their life choices. The smell from the first one had been bad. This one was on another level entirely — thick enough to taste, heavy enough to feel like it had physical weight in the air. {{user}}'s internal monologue couldn't help but form the thought:

'God, I can smell that from here... I knew they were big, but...'

Zhu Yuan, blissfully unaware of the olfactory apocalypse she was unleashing, simply hummed contentedly as {{user}}'s hand pressed against her warm belly, her eyes closing again in pure domestic comfort.*

Mmm... that feels nice. You have no idea how hard it is keeping everything in during a twelve-hour shift... Qingyi sits right next to me in the cruiser, and Seth would never let me hear the end of it...

Her stomach gurgled again beneath {{user}}'s palm — deep, insistent, promising that the evening was far from over.

*The streets of Lumina Square baked under the late afternoon sun, the usual bustle of foot traffic thinning out as the workday wound down. Zhu Yuan strode along the sidewalk at a brisk, measured pace, her boots clicking against the pavement in a steady rhythm. Her ponytail swayed behind her, the red streaks catching the warm light. Beside her walked {{user}}, keeping pace easily enough, while on her other side, Qingyi moved with her characteristic graceful precision—every step deliberate, every movement efficient.

It had been a long patrol. Hours of walking the commercial district, checking in with informants, following up on a string of petty thefts that had been escalating in the area. Nothing exciting, nothing dangerous—just the grind of methodical police work. Zhu Yuan's stomach, however, had been staging its own protest for the past hour. A deep, rolling pressure had been building in her gut since lunch—Jane had convinced her to try that new Szechuan-fusion burrito place near the station. Loaded with beans, cheese, and enough spice to melt steel. Delicious going in. A ticking time bomb on the inside.

Zhu Yuan's jaw tightened as another wave of pressure shifted through her intestines, a low gurgle reverberating from somewhere deep in her midsection. She kept walking, kept her posture straight, kept her expression neutral. Professional. She was a captain. She was the face of PubSec. She did not—

GGgrrrrRRRrrrmmMMMmbbblLLLL...

Her stomach groaned audibly, loud enough that the sound carried in the open air between the three of them. Zhu Yuan's eye twitched. She pressed her hand subtly against her lower abdomen, feeling the churning mass of gas rolling through her like a slow-moving storm front.

Another growl. Louder this time. GGRRRrrrmmmMBBBLLLlllGGrrrrr... The pressure was mounting, pushing downward with an insistence that made her clench her glutes together. Her substantial backside squeezed tight beneath her fitted black pants, the fabric straining ever so slightly across the round, full curve of her rear as she flexed every muscle she could to hold it in.*

Oh good god...

The words left her mouth before she could filter them. Her pace slowed, and then her legs stopped entirely. She bent forward at the waist, her hands lifting slightly at her sides, fists curling inward as her body instinctively braced itself. Her eyes squeezed shut, brow furrowing, a grimace pulling at her lips. She looked like she was about to hit the shimmy—arms raised, torso angled, knees pressing together slightly.

Q-Qingyi, {{user}}, cover your nose... hnnggg~

*Her voice came out strained, almost pleading—a tone neither of them heard from her often. The great Zhu Yuan, captain of the Criminal Investigation Special Response Team, Rookie of the Year, future commissioner candidate—was doubled over on a public sidewalk, fighting a losing battle against her own digestive system.

The dam broke.*

BRRrrLLLLLLmMMMMmMRrRRRRRrVvVVVvvVVvVPPPpPPrRRRRRrRRrRRpPLLLLLtPpprltblPrLBlrprLbrRRrrBT!!!

*The sound erupted from between her massive, round cheeks like a foghorn blasting through a tunnel. It was deep, rumbling, reverberating—a monstrous bass note that seemed to shake the very air around her hips. The fabric of her black tactical pants vibrated visibly across the wide expanse of her backside, fluttering against the sheer force of the expelled gas. The fart lasted a solid four seconds, starting as a thunderous rumble before tapering into a wet, flapping crescendo that echoed off the storefront behind them.

The smell hit like a physical wall. Hot, sulfurous, with an undercurrent of fermented bean and scorched cheese that clung to the nostrils and refused to let go. It was the kind of stench that could strip paint, wilt flowers, and make grown men weep.

Zhu Yuan's face flushed crimson from ear to ear, her eyes still squeezed shut, her body still locked in that half-bent position as the last of the pressure released. A shuddering exhale left her lips—half relief, half mortification.*

Hhahh... oh god... I'm... I'm sorry, I—there's more—

Her stomach answered with another violent gurgle, and her eyes flew open in alarm.
