-Ppwrrrfft- I felt the air rattle in the wake of Sinder's vapors. Catching a glimpse of her auburn tail fluttering in the exchange of gas. I took it in; a funk that titillated my nostrils with just a hint of peach lingering in the simmer of steam.

“Ooo, that one was hot, I could feel it from all the way here,” I call out from the couch as Sinder finished plating the chips.

“You're Groooss,” she called back, sauntering in with the movie snacks.

My eyes trailed her hind as she walked past.

“You know my face is available, should you ever feel the need to go~.”

Sinder shuffled her tangerine cheeks into the cough and crunched some chips. “Reign, how much of a perv you gonna be today? Sheesh, just shut up, will ya?” Sinder said with a nudge to my shoulder.

“You know what'd shut me up good? Bricking up that wide load of an ass on my face~”

Sinder rolled her eyes with an amused scoff, “Yeah I bet you'd enjoy that.”

I let out a little sigh. We'd made progress, for sure. Least this was better than never talking about it.

As the movie played we sunk back into the couch, putting away chips and exchanging a kiss once in a while. A cozy thursday afternoon.

-Ghhbbrrgglgs- The growl quaked through the very couch, I could feel it rattle up my hind moments before Sinder clutched her barrel. “Ooopfhgs… Reign, pause, pause,” she lamented as she wrapped her hooves tighter.

“What? Honey are you okay?”

“Fine,” she wheezed, “Those enchiladas just aren't sitting that well…”

I peek at her tummy. Opportunity presented on a silver platter, “You know babe, you don't have to get up.”

She peeked at me.

“I mean, I'll help you out~.”

Sinder sucked her lip. “Reign, babe,” she muttered, “I'm serious.”

“I'm serious too.,” I clutched her hoof and peered into her eyes, sharing a warmth built up over years together.

“Babe. Come on, I can hold it. I cant just-”

“It'll be cool. I promise my face's comfier than a cold old seat.”

“Ssnnf…” -Bbrglglpgh- her gut roared once more. “Aah fine, okay, but not a word to any pony else.”

My eyes gleamed. It was really gonna happen. She shuffled up from the couch just enough for me to wedge my head beneath her rear. Slotting my muzzle into the plush curtains of her flanks which billowed over my features, to the twitching brim nestled in the depths of her crack.

“Ommmnnf,” she shuffled awkwardly. “Don't expect to make a habit out of this… this just solves my personal emergency and your pervert emergency in one swoofwhhmmmfg…” she huffed out. -Ghrrbghhgs-

The gurgle of her guts spiralled down her bowels and I felt the reverberation of the orange buns clapping into my cheeks. My face was steaming in the excitement. It wasn't the most romantic moment I could have imagined doing it in, but it was gonna happen. Piping fresh straight from Sinder's fudge factory.

-Ghrghgshtct- Another growl. It was getting close, soon I'd-. -PPPwrrrflllrprprprtsh- The force of the flatulence smacked the flanks over my muzzle, anchoring me to them physically as the gas flooded my features. The heat, the soothing moisture, the… t-the… My face scrunched up. What left my girlfriends' rear was not a fart, it was… a miasma; a dense fog worming its way through the depths of my nostrils, down the corners of my eyes, past my pursed lips, hooking into my senses with serrated jags of rust and burning plastics.

“Phfhaa-. Ooogush... pah-…” I coughed it back, though it only sought its way back into me, after recoiling on the orange buns… Where was the comfort? Where was that tantalizing aroma and peachy character? Every semblance of lewd musk was banished, broiled away until nought but raw vitriol fumigated me. I felt my head pulsating inside my skull… maybe, this one just, was overripe. Yeah, something wrong with it. My girlfriend's fart couldn't be… couldn't be…

“Oomph. O-ok, get ready b-babe…,” she huffed out above me. -Sllpgshrlt- The cheeks clamped onto me, and I watched the brim… twitch. -Cllprth- -Clpprsth- Then gradually, swell, budding outwards, until… -Shhrrllprsffrt- The brim peeled back with a crinkle of wood pulp, the berth of the pucker caving under the girth of raw umber.

The humidity radiating form it was concentrated in the crack and slammed into me; a wall of pungent filth that sprouted through my nostrils and clogged them with an air of distilled mildew. How could it be worse? How could it be… so much worse? I reach up, grabbing onto my girlfriend's flanks. The broom resting on a pair of yarn wads making up her cutie mark had never seemed this intimidating.

“Gmrnnghsa, aah this is gonna be a big one…,” she huffed out above me.

-Gbbrnnpgh- her weight shifted, cheeks, piled onto me, pinning me under the brunt of her body weight. I hadn't realised she'd held herself up until now, when her ass mangled me into part of the butt-groove on the couch, and the pillar of muck, -Chrlrpssgrrrlth- slotted into my maw. It punctured past my lips, this battering ram of congealed fermentation, tugging my lips in the clutches of the gluing ichor coating its surface, subjecting me to the onslaught of manure packing down my maw. It wasn't meaty. It wasn't soft or supple. It rejected all the notions I had painted it up to be. Instead… it was crude oil… putrid tar, barrelling down my throat like a sledgehammer, plastering a skid mark of burnt rubber onto my tongue as it contorted my gullet, malforming my flesh in its invasion. -Sqrrhhrlspqsgh- I couldn't tell if the squelching retch of vibrations was my own tissue distorting, or the mulch compiling…

“Mmgpgsh mfmpsoo. Ooo you can… m… really take it back there, huh?” Sinder huffed.

“Mgpgl Mgpgh,” I couldn't move. Her desperation subsumed me as the ballast unloaded. Torching muck egressed from my partner's hot ass, to immediately marr my lips and plunge into me. Each breath I had to take in went through the tangled web of fractured bile, wheezed through the neck bloated and warping around the contorting salvo of sludge.

-Pfprbrphrrrpt- another puff of gas flushed over me, greasing my face in the noxious air, hooking deeper into the puncture in my nose left by the first bellow. Smelling salt in the wounds. I kept swallowing and swallowing, just for a gasp of air, the cheeks rustling around me.

“Mfmfs. Phoo, that's actually, oomf. I can feel how much your muzzle waited to wedge up my ass…” she huffed out… -Fllchhrlsptah- The mare pinching off another salvo of manure, lounging back in the cough as the bales constipated her boyfriend's entire gullet…

“Haaaamfmsm wwmmmoooo… phew, ooh that's good…” Sinder huffed out, sweeping her cheeks down over me, lingering as her focus drew back to the show.

I brushed over her cheeks, kneading into them, until she lifted a flank.

“Hey perv, sorry if you need some air, I don't think I have any left in me.”

I pried my face out of her crack -Slclrlpsth- with a crinkle of clotting glue, tethers of grease and… grime stretching between our lips…

“Phew, was that ever a cheesy load. So, I'm actually kinda curious, what'd ya think of all my fresh fudge?”

That wasn't fudge. That… was sewage.

“Aw babe you're so cute when you are wide eyed. Don't have to say anything, just bask in the taboo glory of my flanks, the one chance you got it~” She teased and tugged me up onto the couch, wrapping a hoof around my and nuzzling against my neck. “Phew, you reek like a batch of spoiled peaches.”

“A-ah…, yeah, t-that was a lot.”

“But don't think you got full access to my haunches just cause you got there once, ok babe?”

I let out a soft sigh of relief. My head was still steaming… I could – still – taste it in my ears… how?

“Unless…”

I swallowed.

“You ask nicely, or I – really – have to go~.”

I put on a grin and nodded. The bulk of the dump still weighed in my guts…

“Hey, babe? Babe?”

I groaned, turning over in bed, robbed from slumber, feeling the blankets in a tangle over my frame. I peeked up at Sinder, “Mm… y-yeah?”

She beamed, then stifled her expression, “I'm going to the bathroom.”

I blinked, “Okay?”

A soft snicker. “Just wanted to let you know~.” She sauntered off with a sway of her cheeks. I laid back, groggy, yet wide awake. That was, rather frisky of her.

A few days passed without major incidence.

“Pheeo, I don't know what I ate, but I'm, so constipated,” Sinder said as she waltzed through the door.

I looked up form washing the dishes and smiled, “Feeling a bit backed up~?”

“Oooh yes, enough that I don't know if the toilet can survive this load,” she said, lips curling up to reveal a toothy smirk.

“Hope you'll… go easy on it then.”

“Don't know if I can promise that,” she said with a swish of her tail, “but if it chokes on us… I'll be sure, to let you know to clear your throat,” She strutted off with steps that hefted and accentuated her cheeks with soft bounces, waiting between each tread for maximum jiggle.

My eyelid twitched. Just… how serious was she…? It was just banter… right? Right? I tried to think of her rump. -Chrrrllghs- But it only made my stomach knot…

The week progressed.

A dinner home, together. We chatted about the week whilst munching up the refried bean and thistle stew.

“… So then, Tulip did drop her wrench, and you know what happened next?”

“You can't be serous.”

“Yup, I can,” Sinder said proud, “I caught it, hoof only, no magic.”

“Wow, weird how you were just talking about it, and then it happened. Think Tulip dropped it on purpose or was it just a coincidental?”

“She'd have to climb all the way down the house's foundation to get it again. Would be a prank that cost her a lot of construction time.”

“Good thing you caught it, I know I wouldn't have been able to.”

Suddenly, Sinder smirked, “Don't put yourself down, babe. I know something you'd be… an expert, in catching.”

I swallowed, and looked right into her hot, searing eyes, drilling me.

“You know, if you'd like some more of this tasty meal,” she said, putting on her sultry voice, “just have to wait a bit for my gut to be done with baking it… a bit of, re-refried beans, how's that sound?”

-Gllmmp- I swallowed, peered down to the plate. This stew… a mushy glut of dark muck. Slimy strands of thistle forming a membrane. It almost looked like… But, shouldn't have. Was it made on… purpose? “S-so hey, that high rise is gonna have its foundation done by the end of the month, right?”

Sinder blinked, gaze neutered, “Oh, well, maybe another moon, actually.”

“Ah, right. Condo building again?”

“Yeah,” she then corrected herself. “Condos with store-fronts on the bottom floor.”

“Right, so the standard affair.”

“Ee-yup,” she said with a pop of her lips.

The silence hung in the air between us like a stale fart.

Sinder strode past me. -Brrroomfmth- And laid out a haunch clapping fart in my path, a reek simmering up my nostrils. She didn't comment on it. Just strode on. It had been over a week now… She had gotten more frisky with it, though also, quieter. Maybe I should talk to her… eh. That'd be awkward.

-Frlrlspsshth- -Cldlpsthn- A door slammed opened as the toilet still flushed.

“Reign, come here.”

“Sinder? Something you need?”

She wrapped her hoof around my neck and tugged me into the bathroom. The reek still lingered.

“I just finished, and we're out of toilet paper~”

“I'll go pick up som-”

“Oh, babe, just let me treat you to this,” she said as her horn glowed. Restraining me in a field of crystaline energy. She scooched her hindquarters up onto my face -Cslpgtht- “Just get in, there is a little chocolate kiss for you to smooch, babe.”

The tart whistle of tar stung down to my throat, her winking, smeared rim reeking of dead beans.

“Mfbgb babe,” I mumbled. -Sflflpsh- She only slid her cheeks back further. She was serious. With a shaky breath, I let my tongue roll out, and tentatively brushed through her crack -Shrlrlspt-. It congealed in my maw.

“Mfns. aaah. That's, soo nniicee… o-of you, babe. Better thank me proper amsmf fmms, after getting to lap my pucker clean. Don't you like wading down my stinky crack? I know how long you've mfI'vm fms you've waited for this.”

The putrid taste was outmatched by the haunting realization that had nested for too long: Sinder, really, liked it. But I was too embarrassed to tell the truth.

Our toilet paper drained faster that usual. We seldom had any. One time I saw the bin full of crumpled up plies. It wasn't even hidden, more a display of blooming paper… Soon, I was in the bathroom with her every time she went. A waste to buy more toilet paper, when she had me. I Thought I'd build up a resistance to the taste. But the count was on seven now… and It looked glum.

“Oomph… babe,” Sinder said as she dragged me into the bathroom. “I've really pigged out on enchiladas, again. Mmy, worshippable booty, feels like it might explode with creamy, fluffy mare chocolate. You know we can't handle the plumbing bill. Think you could mend me? Tour sweet lips to my hot pucker and give it a thick, muddy kiss?”

My eyelid twitched, biting down on my lower lip and shaking. “Sinder, n-no, I won't.” Saying it shook my spine. She too, froze mid-drag into the toilet, and just stared at me.

It was tough, but, I'd have to say it sooner or later-.

“Oh, for Luna's sake, stop. Enough with this playing hard to get, jam your face up my rump and choke on my dung,” she restrained me, and shifted to jail my face in her ass; I caught a glimpse of her gaze. It was warm. But, unlike the fiery passion we''d shared, this was the tempered, flames having forged it into steel.

-Sgglllrgllrrcht- Her cheeks buried me. -Flsrphthgrlrpgttsss- And she relinquished her load right into me, my face getting caked in a clump of mulch before I was forced to part my lips, and… chug. Chug and feel my tastebuds fry, my cheeks swelling, and my gullet engorging in rolling dunes of warped skin, filth searing my sinews and mangling my maw.

It wasn't fluffy, it wasn't smooth or succulent, it was raw. Raw, gritty, honest. From the spun sugar in my mind to coarse pepper assaulting my throat. “Mmgng smpgahaa oough ayes, amfms, your face feels so good up my ass… get your muzzle in there, fms. You deserve it. You deserve all the attention my ass can give you, fsm, sm eat it all you muck glutton…” she groaned out between pants and shudders. My senses were smothered in the tepid avalanche curling down my neck, constantly congesting my throat.

I tried to close my eyes, to grin and bear it; but locking my other senses, only amplified the vile mulch. -Chrlpgshhyllch- The slimy crinkles of each tough chunk burrowing down my neck and swelling my cheeks like a toad. Trapped in this cage of groggy putrefaction with the feminine manure of my girlfriend’s love.

“Phoo, there.” Sindre said, standing up and fanning over her muzzle. A cough creeping up at eher rear. “Aww, come now. That wasn't such a bad one, or maybe it just wasn’t enough for you. I'll pig out a bit for you over the weekend. But, speaking of…” Sinder said, leaning closer. “Don't you think we… should make it official?”

I shuddered.

“I mean, you've been here for, two weeks? Oh wait, has it been a moon already? Wow, and you've been out like… twice? Thrice? And that's just because I couldn't be bothered to get up~. So, I called a friend over, to introduce us proper~. So sit tight, and be on your best behaviour, alright, mud pie?”

Point Post wiped his brow with a wing, “Just gonna use the bathroom, be back and join you in a sec.” The pegasus called out to Sinder. A bit strange, they'd been playing games for well over two hours, and Reign still wasn't back yet. But, if he knew him, his friend would show up sooner or later. Point lifted the toilet lid.

“F-finnally,” I cried out.

“Whoaoa,” Point stumbled back and dropped the lid back over me. It echoed hollow, but soon he peeked in side. “That's, really you.”

I nodded as much as I was allowed, neck jammed up the toilet bowl, the rest held in a magically expanded chamber in the drains. Stale muck caked the seams where porcelain met my yellow coat. My mane a tangled mess.

“What…? Oooh wow, you finally got your wish. Wow I'd never think Sinder would go along with this,” Point swelled in joy, “You gotta tell me how-.”

“This wasn't my idea.”

“Huh?”

“I don't… I don't like this as much as I thought I would.”

“Huh. And you're, still here.”

“I couldn't say no.”

“Why should, dude, hang on, how do you get out?”

“Whe-when Sinder wants me to…”

“Wus’ that?”

“She lets me out if she can't take her eyes off her who's, but still gotta… take a…”

“Wow…,” Point mulled it over. “That's, pretty pathetic, dude.”

I frowned, “Will you please, please just help me?”

“Ok, ok, dude, I understand. Of course I will.”

I let out a sigh of relief.

“On… one condition.”

“Yes, I'll forgive you for never returning my Playcrate XXX, it isn't even that big a de-.”

“I wanna cum on you.”

The sheer candour broke my expression, “Hh-huh?”

“Dude, you realise how hot this is? How could I miss getting my dick sucked off by a toilet?”

“That's not-. Point.”

“Just a quickie? Please? I know you'll like it too, perv. I've done more than enough erp with you to know what makes you tick.”

Apparently not, when not even I seemed to know tha' I thought, but swallowed. “Ok, I'll do it, just be quick before.”

-Kfthnnnd- The door slammed open. “Point,” Sinder called.

“Woahoa, yeah?”

“You ruined the surprise.”

“Oh, sorry, Reign was just.”

“I'm not talking to you…” she stepped past him, staring down at me, her anger framed in the oval of the white ceramics. “You've ruined everything.”

“B-babe wait-” -Tthndk- The lid slammed shut.

“My sincerest apologies for the toiletry, Point. Come, I think I know a way to… make it up to you…”

I heard it echo in the distance as they stepped out of the bathroom, leaving me again to stew… in stale excrement.

I waited… the day faded into evening. And evening into night. They didn't come back.

-Cttnn- I woke to the creak of the lid, blinking sleep out of my eyes as I stared up at a blur of blue coat, shrouding my vision as it -Thdnwp- planted onto the seat.

“Morning, Reign.”

“P-point?”

“Yeah… pho… y-yeah,” he huffed. I saw his stallionhood droop down, a trickle of urine introducing an acrid air of ammonia in the stuffy bowl. Though this odour intermingled with dried sweat, and crusted, briny musk… His dick still pulsed as the bowl stunk of lovemaking.

“P-point… what did y-you do?”

“Phew… I know what you like in her, Sinder's… a cougar. I couldn't, hold her back, sofas eventually I stopped.” -Ppfbrhrhprth- The burst of smog echoed in the bowl, reverberating with the realization, integrating it with the reeking air of wilted garlic boiled in asphalt. I coughed, wheezing weakly.

“Y-you-…”

“Eventually. I just stopped holding her back, sh-she had some, fmsm, convincing bargains.” -Clrlptah- his pucker creaked open, throbbing back and forth with a patch of barf yellow, beige mulch.

“H-hey. W-wait. W-wait. Y-you are still gonna free me?”

“Mrmg. I've really gotta drop this batch, kept it since yesterday…”

“B-but… I-I'll suck your dick, y-you'll get your cock serviced b-by a w-willing toilet,” I pleaded.

“Fmpagh… -Cllrrp- Sorry, bud… Kinda, all out, I spent my spunk at Sinder's back bank. Mmms, made a huge rear deposit,” he huffed out, and strained as the pit pried open, peeling over the salvo of prickling manure…

I opened up, letting my jaw hang low. It was instinct. If I didn't… it would stick to me. Linger and ferment further into my hide, or worse… entomb me under the avalanche of gunk. So, I felt my friend's filth percolate past my maw, staining my gob in the salty vinaigrette of rectum baked clay. It wound down my throat. -Gllgmghs- -Gmnglshlt- Each swallow budged the alcove in the percaline around my neck, swelling my gullet to fill with the space, and if I didn't swallow it fast enough… then… first it ached, then it pinched, choked. -Glpgghs- -Glrrpgst- But, it was routine now. I'd done it too many times. I functioned as intended… slotted into my role as the entrance to the sewers, the drain pipe below. -Gbghglspah- My stomach jostled, engorged into its own socket, though unlike the one for my neck, this one was spacious… I only felt the side of my stomach brushing against it, and ahead was an abyss. How much manure could I store at a time? How much had Sinder imagined I could hold?… How much did she account for?… I was lost in the vacancy of an answer, so I could only guess, guess, and dread. Dread that I would never find out. Dread… that one day, I would.

“Mmpfgh sampaha. Oooh yfoo. I needed this… this mess's been like a butt-plug all night, with how much I've rocked it,” Point huffed out, wiping his brow again and lounging back, giving me only the sliver of light between his thighs.

-Glpggsmp- -Ghhppfunkt- The pinch and tug of my neck against the ceramic… my sinew warping and straining under the bulk of muck radiating pungent steam… He barely acknowledged me… I rattled through tired, stale muscles.

“Pho, but gm yeah, maybe if I go alognmsmfs, with this a bit more, we could set up a threesome. And then, hey, we'll get you out, so, fmms, just gotta be patient. Fmsm, hfmppo, oh yeah, get your muzzle up there, I'm not the best wiper.”

In the darkness of the toilet, in the shade of the cheeks, I only got to see in the twilight between the lid opening, closing, or the hind resting back on me. That was all a toilet bowl ever saw of the light, after all. Unless something was wrong with it. I feared, that I'd find out the limit of the gut socket of the tube encasing me. Dreading that I'd have to be… fixed, replaced. Or… if I'd just… meld into the piping, stop being me, and just… disappear…

Point neglected to say goodbye - the only goodbye I got, was the clatter of the lid. -Cltlprhhths-

-Pfppthtpht- -Cbbrrllrht- “Haaa, I can't believe you'd embarrass me that much. I thought you'd be a great toilet, you've pestered me since before we got together you know. Least you can do itfsamm, work.”

I stayed silent.

“Oh, and babe, don't worry, That whole fling with Point, one-off thing, just to get the mood up. Really it's your own fault. But, we did work out a compromise.”

-Cllfpthcchtrt- -Kkrllpdtthhllchp- The manure crawled down my throat, a bloated anaconda choking me from the inside out. The filth creaking like mud brought down on a stack of autumn leaves.

“I've given him free access to you. Whenever he comes over, for dumps, or more, lewd activities. Might as well, right? Gotta train you up to be a functioning toilet,” she said and lifted one haunch to peer at me, “Ain't that right?” -Cltpsths- she dropped it before I could even emote. “So, because of that, I've decided, why not just do it with a bang?” she held down her phone, the fluorescence of the screen guiding my eyes to the text. A party, and a list of accepted invitations. “All our friends are coming over. One huge party, all of ‘em saving their loads just for you.”

I quivered, wheezed, “Mgmpgsh mfhwhwffs.”

“Yes, we've all gotta show them what a good toilet you are, right?” she said, smashing her cheeks down to cram -Flrrlsptth- the muck back down my throat.

I stared at the screen, seeing everypony's comments.

'Urch, disgusting.'

'Gotta see it to believe it.'

'Yeah, but can you imagine?'

'Yeah, I can, as finally our little mud foal can realise his dreams.'

'H-hey, I've kinda come down with something, I might still be a bit… runny by the time of the party, that ok?'

“Oo,” Sinder said, and typed a reply. “Of course, our toilet can swallow, erhm, flush, anything~”

I recognized her tone as I choked back her muck. She peered down at me, her eyes lighting up in the silhouette to the sliver into my ordinary life. Her gaze glancing past me, the fire had gone out, cold and not in a sense of contempt, but as if there was nothing to see.
