(This begins immediately after the fifth part, “Mommy Teaches Megan About Scat – Part 5”. And remember, this is a fantasy – do not do this! Really!)

(NOTE: This is the conclusion to “Mommy Teaches Megan About Scat.” However I do have plans to follow this up with further adventures that will take these ladies into some new extreme, scat-based perversions.)

A voice in the back of Megan’s mind was sort of beginning to wonder whether this night may have just gone too far, and that Mommy, Grandma, and the rest of this shit-stained crew could possibly be insane and/or dangerous.

But as she climbed down the slick, nasty ladder rungs that were bolted to the wall of the access shaft, she caught the smell of raw sewage in the sewer below and felt her cunt dribble. After all the action they had already been through that night, the scent of sewage was getting her riled up.

About halfway down the ladder, a small side tunnel veered off. It was only about three feet tall and a slick, nasty smell wafted down. Mommy deftly slipped off the ladder and into the dark side tunnel.

The tunnel was almost pitch black and Megan could barely make out her mother’s shit-stained ass as she crawled the the filth. After about thirty feet that felt like miles, they came to another ladder leading up. Mommy climbed the ladder, pushed the manhole aside, and climbed out.

Megan followed and looked around, realizing they had come out in the port-a-john place. The scent of shit and piss was only partially masked by the scent of deodorizers in the darkness. Megan looked around and was about to comment on the darkness when suddenly floodlights cut the night and the entire area was lit up like daylight.

Standing off to one side were four women who were clearly related and were all wearing cut-off T-shirts and thong bottoms – and nothing else. The T-shirts were all emblazoned with the logo of the port-a-poddy company and were cut off just low enough to cover the chests – barely.

“Wait, don’t tell me I am going to meet even more hot lesbian incestuous scat queens tonight?” Megan murmured.

“Let me introduce you to the owners of this fine establishment, ” Mommy said. “Four generations of scat queens.”

“Four generations?” Megan gasped. “How does that even add up?”

“Like this, ” Mommy replied. “The eldest on the left with the big fake tits, dyed blonde hair, and the sculpted body, that’s Geneva. She’s 73 and is still a fucking shit slut. You haven’t seen a prolapse until you’ve seen what that aged body can shove out of her ass. The next one with salted hair, the natural mom tits and the fit ass is Anna. She’s 55 and has bad IBS that she doesn’t bother treating because why ruin the fun? The next one that looks like a bleach blonde fitness instructor – and who keeps all these ladies in shape – is Hermione. She’s 37, and if you see her reach for a strap-on, you know you’re in trouble. And the one on the right that looks like a teenage model, that’s Paige. She’s 19 and still learning the ropes.”

Mommy pointed to Megan. “And this, ladies, is Megan. She’s getting indoctrinated tonight, and you’re the last stop before the final degradation.”

“Wait...what’s the final degradation?” Megan asked.

“You’ll find out later, ” Mommy replied.

“It’s nice to meet you, Megan, ” Geneva said, approaching and shaking her hand, along with the other beautiful women in her family. “It looks like you’re off to a good start. Is Beatrix going to join us?”

“Here!” called Beatrix from behind and she and Cornelia climbed out of the sewer manhole.

“Oh good, ” Geneva said. “It’s fun time.”

She walked across the lot to an electronic switch on a pole. Beyond the switch was some sort of a pool or holding pond about thirty feet wide that was covered with a metal plating of some kind. Geneva threw the switch and the plate began pulling back. Underneath was a pool about half full of raw sewage from the port-a-poddies.

“Is this, like, code?” Megan asked. “I thought this waste had to be stored in a sealed tank or something.”

Geneva giggled and her big artificial tits shook under her top. “We pay the inspectors a little, you know, extra, ” she winked. “And we even throw in a blow job now and then. And we also use natural treatments in our johns, that way the sewage is safe for our little games.”

Hermione had walked to a row of port-a-johns that were lined up on a ledge overlooking the far side of the cesspool. Another row ran along the side. Each of them had a little tap attached to where the draining hose was supposed to be plugged in. Hermione slipped into the cesspool and ducked under the filth, coming up with her cut-off T-shirt stuck to her medium-sized tits with filth. She slicked her hair back, then pulled a handful of filth up and gulped it down. She slipped over to the first portable shitter and opened the tap just enough to start a slow flow of sewage.

Megan gulped as she watched Hermione act like she was an actress in a beach movie under a shower. She rubbed the filth over her skin, peeling off the top and licking the shit and piss off her tits. Next she leaned in and opened her mouth under the spigot, sucking down several loads of nastiness and swallowing it.

Geneva dropped into the cesspool and moved over next to her granddaughter. She took Hermione’s hair and pulled her head back, holding her mouth under the spigot that was still pouring out shit, piss, and got knows what else. Hermione coughed and sputtered, but managed to swallow gulp after gulp, her fit, washboard tummy starting to bulge.

Finally Hermione grabbed Geneva’s arm and forced her to let go. Hermione pulled back and sputtered, then slapped her grandmother across the face. Both women giggled and Hermione pulled off her grandmother’s top, revealing her huge, artificial tits, topped with nipples that had to be at least three inches long, pointing upwards and hard as darts.

“You may be my grandmother but you are always a total bitch, ” Hermione said as Anna came up behind Geneva and squeezed her tits.

“It runs in the family, ” Anna said. “Ooh, I feel something coming on...”

She leaned over the side of the pool and spread her legs. Geneva pulled her daughter’s cheeks apart while her granddaughter slapped Anna’s ass. Like all the other women Megan had met tonight, Anna’s ass yawned open for a moment, then a thick mountain of pink assflesh tumbled out. It stuck out over six inches with a gaping hole at the tip. Megan knew what was coming next even without Anna commenting about her IBS acting up.

A moment later a fountain of shit ejected from Anna’s ass, prolapsing her even further as Geneva (Anna’s mother) and Hermione (Anna’s daughter) leaned in and began licking and sucking the shit that was gushing out.

Megan couldn’t stand by and watch any longer. She glanced over at Paige (Anna’s granddaughter), who had been standing by and watching. She gestured towards one of the spigots and Paige nodded. Megan grabbed her mother’s hand and hopped into the cesspool as Paige stripped off her T-shirt and thong and joined them.

Mommy Elise, Megan, and Paige leaned into a three-way kiss under a spigot of port-a-john shit that Paige opened. It ran down their hair and across their face as they swapped mouthfuls of the nastiness. Paige and Megan licked and sucked filth off of Mommy’s tits, then Mommy bent over and the girls double-fisted Elise’s shitty inside-out asshole past their elbows.

As she and Paige reamed out Mommy’s ass, Megan looked back over at Geneva, Anna, and Hermione. Hermione, who had been gulping down load after load of sewage was now bent over Geneva’s asshole. The 73-year-old may have been a marvel of modern medicine, but they had never tightened up her asshole or cunt, because her ass was prolapsed so heavily that Megan was sure it would take three hands to shove it back in. And as she watched, Anna wrenched the shit-covered prolapsed open and Hermione unloaded all the shit sewage she had been gulping down into her mother’s yawning bottomless asshole. And as if that wasn’t enough, Anna pulled her grandmother’s prolapse out even further, stretched it like curtains, and pulled it up so it looked like a pink flesh airline airsickness bag sticking out of a ruined, wrecked, grandmother asshole.

Megan practically came at the sight. She felt the load of sewage she had been gulping down gurgle in her tummy. She knew where she wanted to unload it. As Hermione pulled back from her own mother’s asshole, Megan moved in.

Geneva looked back over her shoulder and smiled. “Give me all your shit puke there youngster, ” she said. “There’s plenty of room left.”

As Megan moved into position, Paige shifted another port-a-john into position and opened the tap, so a fresh load of sewage began pouring down over Celeste’s head and down her back, puddling in the small of her back above the stretched prolapse that Anna and Hermione were now holding open with two hands each. The pink shitty flesh had streched even further and looked more like a grocery bag than an airline sickness back. Megan leaned in and licked the insides of the ancient assflesh, tasting Hermione’s puke, the load of sewage, and Geneva’s shit. It was a heady, delightful mix.

Megan leaned in, her face completely engulfed within the older woman’s prolapse. She squeezed her throat muscles once, twice, then a third time, and unleashed a load of shit puke into Geneva’s bottomless ass. Her stomach muscles convulsed as load after load of scat vomit poured out of her gullet. It felt like Megan puked for hours, but Geneva took it all.

When Megan finally felt empty, she leaned back. Geneva smiled and stood up in the filth, her stomach stood out like she was pregnant and sloshed when she walked. She climbed out of the cesspool and knelt on the side. Her asshole was hanging out well over a foot and the pink shitty flesh was gaped, looking like a shitty hole to hell. She reached back, pulled her asshole flaps open even wider, and slowly began shoving out the load of puke she had just taken in, emitting a long, foul squirt of shitty puke that sprayed all over the girls standing behind her.

All the other girls had joined them in the cesspool and now they were vying for mouthfuls of Geneva’s anal ejections. It reminded Megan of bridesmaids at a wedding struggling for the bouquet. The women – all eleven of them not counting Geneva – pushed and shoved in the cesspool, giggling, laughing, rubbing bodies together lubricated by sewage, shit, piss, puke, and everything else that comes out of a port-a-john. Megan even spotted maggots and fly eggs in the mess and pulled them up to her mouth, gulping them down along with the other sewage. It was a big, nasty, messy free-for-all of filth. Hands groped, bodies rubbed, tongues found assholes, everything that was imaginable for a dozen hot, slutty, incestuous scat lesbians happened in the scat scrum. Megan felt a fist and an arm slide up her asshole, then another. She didn’t know or care whose it was. All she knew was that it was amazing. They pulled her open even wider and someone slid a third arm in. She came again and thought she was going to lose consciousness as she shoved her face into someone else’s prolapsed cunt and sucked shit and a little blood from someone’s cervix.

What the fuck. It couldn’t possibly get any crazier than this, could it?

Megan felt the arms slide out of her asshole and turned around. Mommy Elise was slipping back from the scrum and gesturing to Megan to follow her.

“Is there more to this night?” Megan asked.

“Just one more thing, ” Mommy said and led Megan back to the sewer manhole. They dropped down the ladder, but instead of slipping into the side tunnel leading back to the race track, they slipped all the way down into the bowels of the sewer.

Mommy dropped down to a walkway and flipped a switch. The sewer tunnel lit up under a string of bulbs that had been hung from the top of the sewer. It didn’t look particularly code.

“We pay the sanitation workers a little each month, along with the occasional BJ, to keep them quiet about this, ” Mommy said. “You can definitely help with that.”

When Megan dropped down next to her, she took her daughter’s hand and they walked about fifteen feet down the walkway next to the sewer channel and into a larger sewer junction.

Megan gasped.

The junction chamber was probably about thirty feet wide and looked like it had been built in the 1800s. The walls were brick that was coated with a layer of filth. Tunnels led off upwards different directions, and there was one downhill tunnel, clearly the direction that the shit was supposed to flow. But the chamber had a pool that was at least twenty feet wide, who knew how deep, and it was filled with shit, piss, and all sorts of foul nastiness that goes into making sewage.

In short, it was amazing.

Mommy began pointing out tunnels. “That tunnel there brings down the shit from the casinos next to the racetrack. That tunnel dumps out the shit from the hotels across from the casinos. That tunnel there dumps out the poop from the restaurants. And that tunnel dumps out out from the residential areas like our neighborhood. Then they all end up in this pool and then cascade through the grate down the downhill tunnel that leads to the filtration plant.”

As she said this, a big, thick nasty surge of sewage coursed down the tunnel from the casinos. It splashed into the chamber about waist high, knocking Mommy to the side and sending Megan splashing into the disgusting wave of waste. Shit and piss and who knew what else went up her nose and down her throat. She came up sputtering for air, then swallowed and smiled.

A moment later another surge washed down from the direction of the restaurants. In addition to the standard shit and piss mixture, there were food scraps, globs of grease, and some chunks of vomit.

The pool at the center of the chamber swished and sloshed, finally settling down to equilibrium.

Behind them they heard footsteps as hot curvy GILF Grandma Celeste, hot curvy Aunt Misty, slim-but-busty cockgirl cousin Lilac, chubby sag-titted neighbor Cornelia, her daughter curvy Vera, her other daughter, barely 18 and super slender Beatrix. Plus there was ultimate scat GILF Geneva, her daughter Anna, her granddaughter Hermione, and her great-granddaughter Paige. And of course, Megan and Mommy Elise.

“What the fuck, ” Beatrix mumbled. “This is...wow...an hour ago I wouldn’t have believed I would be saying this while standing next to a pool of sewage...but this is hot.” She reached over and squeezed her mother’s saggy, shit covered tits.

Something stirred in the filth and Megan took a step backwards.

“What the fuck is that...and that...and that....what the fuck...!”

Several things were slithering and swimming about under the surface of the shit pool. Finally one of them popped up and pulled itself out onto the walkway next to Mommy, standing upright next to her.

The thing stood about six feet tall. Half of that was a three-foot long body that looked like a traditional squid body – long, slender, and bullet shaped with eyes on the sides – though this one had a slight swelling at the tip, giving it a marginally cock-like shape. The other half of that six feet were ten long, strong tentacles that it now stood up on like it was a person. It’s eyes moved around between the group of women, finally coming to rest on Megan.

“Wow, ” Megan said. “Does...he...she...it have a name?”

“Well, you know, ” Mommy said with a smile. “This one that is the first one we met, we named him Pooh. You can identify him by the little scar above his eye.”

“Well, that makes sense, ” Megan said, looking at Pooh skeptically.

“Then we got carried away, ” she added, pointing to the other Scatapii that were emerging from the sewage. “The slightly gray one is Eeyore, the pinkish one is Piglet, the brownish one is Rabbit, the one with the particularly prominent membranes is Owl, the striped one is Tigger, the chunky one is Kanga, the smallest one is Roo, and the one that’s sort of whitish is Robin. There are a ton others we haven’t named lurking around in here. They are rather passive and usually only come out to play if all the others are...um...occupied. So there are more than enough Scatapii to satisfy whatever we want.”

Megan looked around. The other women were streaming into the chamber. All eight women were beautiful and hot, coated in shit – human or equine – from head to toe, along with no small amount of puked shit too. They stood in a row next to the wall while the Scatapii stood on the edge of the sewage pool.

“So...what now?” Megan asked. “Isn’t this some sort of animal cruelty?”

“Not at all, ” Grandma Celeste answered, moving forward and wrapping her arm around Tigger as the Scatapus slipped one tentacle down across her shit-covered tits and slid another one around her back. The way that Celeste gave a little squeak, Megan was pretty sure that tentacle had gone up her Grandmother’s deep, gaping asshole. “Do these creatures look like they are being forced into anything?” Celeste asked.

The creature that Mommy had called Piglet was reaching out for Megan, tentatively sliding one of it’s tentacles up the inside of her leg. The fleshy appendage was soft and slimy, and coated in sewage. In fact the slime that they exuded seemed to be mixed with their shit. Another one of Piglet’s arms wrapped gently around Megan’s arm and tugged her towards the sewage pool.

“Is this...safe?” Megan murmured, looking back over her shoulder at Mommy.

“We’ve been doing this for years, and we’re fine, ” Celeste said, sliding into the sewage pool with Tigger. She reached back and yanked her asshole open, allowing Tigger to shove several loads of sewage up her asshole.

Megan felt something gurgle deep in her stomach. She had been empty for awhile, was more shit moving down in her system? She saw Vera rub her stomach too, then Cornelia giggled.

“Earlier this evening I laced the horse shit pile with laxative. Anything you still have in your system should be working it’s way out now.”

Megan just had enough time to emit an “Oh fuck” before a muscle contraction in her bowels forced her ass to prolapse and dump a wet load of shit down her thighs and legs, landing on the walkway next to the shit pool. Mommy and Grandma leaned down and began licking up the pile of Megan’s scat as another load poured out of her ass, this time mostly liquid.

Mommy and Grandma were on their knees on the walkway, licking and gulping down Megan’s shit. Megan looked at the Scatopii. Tigger was now hovering behind Grandma, three of it’s tentacles had pulled open her asshole insanely wide and was tugging out her pink prolapse. Six inches, nine, a foot of shit-covered flesh. Then even more.

“What the fuck, Grandma, ” Megan said. “That’s insane, how far out can your asshole go.”

Celeste and Mommy finished up the shit pile Megan had made.

“Granddaughter dear, the Scatapii have a chemical in their slime that loosens up your asshole nicely. You will be amazed how far out your ass and pussy will slide under their ministrations.”

Mommy looked up at Megan with a literal shit-eating grin. “I’ve been spiking a little of their slime into your morning smoothies the past couple of months. How do you think you went from virgin asshole to destroyed anal shit whore in just a few hours?”

“Oh you bitch, ” Megan said. “You manipulative bitch.”

“And you love me for it, ” Mommy replied. Megan leaned down and slapped her mother’s shit-covered face, then kissed her and vomited shit into her mouth, spraying both of them with shit puke.

“Mommy, you were a shit whore long before I was, ” Megan said. “I don’t approve of slipping me a mickey...but I love my new gaping shitty ass.”

“Do you know what the last stage of your indoctrination is for you and Beatrix?”

“I don’t know but I can’t wait...”

Grandma Celeste stood up and Tigger wrapped two of its tentacles around her waist and one underneath between her thighs. It pulled itself up onto her body like a giant, three-foot-long tentacled cock. Megan noticed that Mommy and Pooh had made the same move. Around her all the women – except her and Beatrix were arming themselves with three-foot-long Scatapus cocks. Lilac, though, didn’t need one, her real cock was throbbing and hard and over a foot long – must be another side effect of these creatures.

Megan looked at Mommy, who was now stroking the Scatapus cock.

“Does that go where I think it goes?” she asked, running her hand up Mommy’s pendulous tits that were now coated in sewage from the latest surge of filth that coursed down from up the tunnels.. She collected a handful of shit and vomit, and gulping it down.

“You and Beatrix, get in the pool and bend over against the walkway.”

Beatrix and Megan looked at each other, then kissed, swapping a mouthful of shit puke Megan had just brought up between them before letting it trickle down across Beatrix’s barely-developed chest. The girls dropped down into the pool, finding the water was only about three feet deep, and leaned against the walkway, side-by side, their prolapsed, shitty assholes hanging out

Mommy Elise stood behind Megan, and Cornelia stood behind her daughter Beatrix. A row of four big mom-tits with scatapus tentacles wrapped around their bodies, the three-foot-long scatapus bodies extended out in front, pulsating and throbbing. Additionally tentacles wrapped around big mom tits or penetrated gaping cunts, pushing into cervixes.

Mommy and Cornelia simultaneously drove their three-foot-long gigantic scatapi into their daughters’ shitty, ruined, prolapsed assholes.

Megan’s moan echoed in the chamber as her mother pushed all three feet of hard throbbing flesh into her bottomless yielding asshole. Sewage and shit squirted out around the flesh as Megan’s ass stretched in new ways she would never have through possible. She moaned again and as her mother’s soft tummy bumped against her substantial ass, she pushed her head underwater to keep herself from screaming at the crushing orgasm coming over her. She swallowed several mouthfuls of sewage then emerged, gasping, as a fresh load of shit from the casino tunnel came down like a tidal wave of filth, coating them all and almost knocking them over. But somehow Mommy and Megan held on, and Mommy continued her destruction of Megan’s asshole.

This was beyond disgusting. And it was so fucking hot.

Megan looked over at Beatrix. The slender other girl had her eyes closed, her body coated in filth, her hair slicked to her body with it, and looked like she was coming for the dozenth time. Just looking at Beatrix’s hot young body getting wrecked by her mother in a pond of sewage made Megan come again.

Something slithered in the water. It was another Scatapus between Megan’s legs. It slide four tentacles up the inside of her thighs, then pulled open her already gaping pussy even wider. Her cunt prolapsed from the pressure inside her ass, and her cervix gaped. Suddenly three shit-covered tentacles were inside Megan’s womb, stretching it open. Megan moaned and came again. She wasn’t sure how much longer she could take this.

Mommy wrenched her scatapus-cock out of Megan’s ass, leaving it prolapsed over a foot. Shit and sewage covered the pink flesh. She looked over her shoulder to discover that Mommy and Cornelia had traded places. Chubby Cornelia drove her Scatapus cock into Megan’s ass harder than her mother had. Megan moaned as she realized that the creature had wrapped several of its tentacles around its body, making the shaft thicker and meatier, stretching her asshole even wider. Megan’s anal destruction was continuing apace.

A fresh surge of sewage washed over them, forcing the Mommies to slow their pace for a moment, but only a moment. Cornelia ripped the scatapus cock in and out of Megan’s shitty ass, slapping her stomach against her cheeks. Megan lost wtrack of how many times she had come.

When Cornelia was finished, Grandma Celeste took a turn, then Vera, then Geneva, then Anna, then one after another all the women took a spin in Megan’s and Beatrix’s shitty wrecked assholes. Megan moaned. Megan screamed. Megan came and came and came. Whatever the scatapus had done to her asshole, it was amazing because she could feel her flesh hanging out of her body, her asshole getting stretched until it was unrecognizable, but there was not tearing, no blood. It was breathtaking.

Finally, once everyone had a turn – including her cousin with her real cock – Mommy came back around. She still wore the scatapus wrapped around her body like a cock, except the tentacles that weren’t used holding the creature to Elise’s body were wrapped around the creatures three-foot long shaft. It made it immense, long, and thick.

“Oh God, ” Megan moaned as her mother slid that gigantic shaft into her shitty, sewage-filled asshole. It was breathtaking, amazing. Megan came one last time and when Mommy wrenched free, Megan’s shitty assflesh almost hung down to her knees.

Megan leaned over to Beatrix and the two hugged as the other ladies clapped. Scatapii wriggled in the filth as a fresh load of sewage wafted down from one of the tunnels.

The two girls looked around at the other women.

“So do you have any other nasty surprises or is this it?” Megan asked,

“Oh, there’s one more, ” Grandma Celeste said. She pointed to the choker that she had worn around her neck the entire evening. “This is a camera.”

“What?” Megan and Beatrix said, simultaneously.

“There are also several hidden around this chamber, in our backyard, and we even hid a couple near the manure pile upstairs.”

“What is this, blackmail?” Beatrix said, looking nervously suspicious.

“No, dear, this the internet age. Lots of people pay good money to see a bunch of incestuous lesbians eating each other’s shit and wallowing in sewage.”

“Wait...have you been livestreaming?”

“From when you and your grandmother were eating each others’ shit – yes. And we’ve made a ton of money.”

“My god...that’s...” Megan hesitated.

“That’s fucking hot!” blurted out Beatrix. “Incestuous prolapsed shit lesbian camwhores. I’m the luckiest girl alive.”

“Wow...this night has been amazing, ” Megan said.

“And I think there are many more adventures ahead of us...but not tonight. I think this is enough for one night.”

“I guess so, ” Megan replied, sighing. “But I’m going to hold you to that part about more adventures.”

Mommy reached back, dumped a handful of shit into her hand, then took a mouthful and leaned into Megan for a shit-kiss. The two swapped Mommy’s shit back and forth.

“Please do, ” Mommy said as Megan puked in her mouth one last time...

THE END (of this story, but these ladies will return in more adventures)
