(This begins immediately after the third part, “Mommy Teaches Megan About Scat – Part 3”. And remember, this is a fantasy – do not do this!)

Mommy, Megan, and Lilac started towards the back door, but Celeste hovered back.

“I’ll be right out as soon as I whip up some more of the horse manure shit substitute for myself. It seems my granddaughter ate most of what I had in the tank.”

Megan giggled and followed her mother and cousin out onto the patio. Misty was already out there sipping a glass of wine in the setting sunlight. She handed some to Megan, Lilac, and Mommy.

“It looks like you ladies got started without us...again, ” Misty said and twisted Megan’s shit-covered nipple playfully, then leaned forward and licked a swath of shit from the flesh mound. “If you keep doing this I’m going to get a complex.”

“Mommy and I are loaded up with the horse shit mixture Grandma made, ” Megan replied, teasing. “You can eat my shit whenever you think you’re ready.”

Misty laughed, but there was an edge to her laughter. “Pretty bold for a newbie.”

“I’m a fast learner, ” she said, sitting down on the edge of the chaise where her aunt reclined. “And I’m sure there are plenty of things my beautiful aunt and cousin can teach me.”

Misty looked over to Mommy who was standing by the door watching.

“Elise, you’ve created a monster.”

“She’s a natural, ” Mommy replied.

Misty ran her fingers up Megan’s bare, shit-covered stomach, collecting a handful of Celeste’s shit. She brought it up to her mouth and licked the scat off her fingers.

“Want to taste some of your aunt’s poo? I promise you it’s better than your mother’s.”

“I’ll me the judge of that, ” Megan replied. She ran her hand up the inside of her aunt’s thigh. She felt Lilac’s fingers sliding up along her side. She leaned her head back and shared a kiss with her cockgirl cousin, feeling her firm tits against her back and her cock tenting the sundress and pressing between Megan’s thighs.

“You know the best way to taste my mother’s shit?” Lilac murmured in Megan’s ear. “It’s licking off my throbbing cock.”

“Fuck yeah, ” Megan whispered back, sharing another kiss with her cousin. “Show me.”

Lilac stepped back and dropped her sundress to the ground, stepping out of it and standing in the fading sunlight naked, her immense nearly-footlong cock purple and pulsating, long veins wrapped around a shaft that stood up hard in front of her lithe-but-busty form. Lilac’s cock really was almost as thick as Megan’s wrist, and a long streamer of pre-come was hanging down from the gaping tip.

“Oh God, ” Megan whispered. “Show me your mother’s shit on that humongous cock.”

Misty was now kneeling on a lounge, her asshole in the air. Her ass wasn’t quite as wrecked as Grandma Celeste’s had been, but it was pretty close. Her meaty lobes and her raggedy sphincter practically merged into one big, scarred, demolished mass of flesh. She took a bottle of lube and dumped a load down her yawning asshole, then coated her hand, reached back, and shoved her hand and forearm almost to the elbow into her own wrecked sphincter. She gave it several hard strokes then slid it out. Her arm came out covered with shit. She immediately brought it up to her lips and began licking the scat from her arm.

“Oooh, ” aunt Misty moaned. “My shit is perfect.” Her prolapsed flesh hung out of her asshole nearly a foot and was coated in shit.

Megan watched then as her cockgirl cousin gave her immense cock a stroke, dumped a bunch of lube on it, then added a handful of shit from Misty’s asshole. Then she used three fingers from each hand to pull open the hole at the end of the prolapse dangling out of said asshole, and drove her eleven hard inches into her very own mother’s yawning, ragged, shit-coated hole in one solid stroke. Lilac shoved her cock into her mother’s shitty asshole so hard that the prolapse couldn’t slide back in but instead formed a shit-covered pink ring outside the ragged chasm of a sphincter.

Lilac’s balls were tight against the base of her cock and pulled slightly forward. With an additional thrust. Lilac shoved her balls inside, too, knotting her mother.

Misty moaned and smiled, looking back over her shoulder at her daughter.

“Fuck my dirty little ass, ” Misty said to her cockgirl daughter.

Lilac didn’t even respond with words, but instead began savagely pounding her mother’s filthy prolapsed asshole. With each stroke out more assflesh and poop slipped out, and with each hard stroke back in, squirts of shit were sent flying, coating Lilac’s stomach and thighs with shit. The wet slap of Lilac’s abdomen against her mother’s substantial, shit-coated ass resounded in the yard.

Megan watched as her cousin destroyed her aunt’s shit-coated asshole, rubbing her cunt and shoving chunks of poo inside.

Lilac leaned over as she drilled Misty and grabbed her mother’s tits, squeezing them and eliciting a moan from their owner. Then leaning back, she picked up the pace even faster, pounding her nearly foot-long, inches thick cock in and out of Misty’s wrecked ass.

Lilac moaned and stopped. She closed her eyes and arched her back. Megan could tell she was about to come.

Misty wiggled around on the end of Lilac’s pole for a moment, shifting around the poop inside her body. A second later soft shit began sliding from Misty’s asshole around Lilac’s meaty cock and balls. Lilac slowly began sliding her cock out of her mother’s asshole, re-prolapsing Misty’s ass and coating both assflesh and cock with a thick, nasty layer of shit.

Megan felt her mouth water and had to shake her head. When the day started she would have been mortified by the idea of her mouth watering from watching her cousin pull her shit-coated futa cock out of her aunt’s asshole. But now she was just dying to get down on her knees and lick every grain of poop from Lilac’s gigantic, filthy cock and her pulsating balls.

Slowly, inch after inch, Lilac slid her cock from her mother’s ass, until finally the head slipped from the now-gaping prolapse hanging out of Misty. Immediately, Megan dove in, licking and sucking Lilac’s throbbing meat, devouring her aunt’s juicy shit and Lilac’s musky semen. She ran her tongue up and down the shaft, pulling off mounds of jizzy shit, rolling it around her mouth, and swallowing it.

Misty, meanwhile, moved over and pulled Megan’s ass upwards so she was on all fours as she licked and sucked Lilac’s cock. Megan felt her aunt run her tongue around her asshole and pull her young, tight sphincter apart.

“Let me taste your shit, baby girl, ” Misty murmured.

“I’ve been waiting for you to ask, auntie, ” Megan replied, and began pushing out the load of horse shit mixture that her grandmother had filled her up with. The load was warm and wet, sliding slickly out of her ass past her slightly gaped asshole. Misty gently pulled Megan’s ass open wider and pressed her lips to the young sphincter, sucking the shit from her stretched hole.

Megan, meanwhile, was running her tongue up and down Lilac’s cock that was coated with her own mother’s shit. She could feel Lilac’s pulse throb through the veins running along the meaty pole as she flicked tongue-fuls of the scat into her mouth, swallowing each mouthful down and then flicking in more.

Lilac reached down and ran her hand through Megan’s hair and Megan looked up at her cousin with doe-eyes, her cheeks coated in shit. Lilac gently grabbed Megan’s hair and held her face near the tip of her cock.

“How deep down your throat do you think you can take my shit-coated cock?” Lilac asked.

“Baby, my asshole may have been virgin territory when I woke up this morning, but my lips are old school, ” Megan replied. “Slide your cock into my throat. Make me puke back up all your mother’s shit I just ate.”

Lilac smiled and began pushing her shit-covered cock into Megan’s lips. Megan felt her mouth stretch and her throat being pushed open wide. She had taken a couple of big cocks down her throat before, but nothing like this – suddenly she was having second thoughts about deep-throating this immense pillar of meat. It was made worse by never before having sucked a cock covered in shit. And never before with her stomach loaded with shit and threatening to explode.

But she had to admit, tt was amazing.

Meanwhile, Misty had pushed three fingers into Megan’s young, tight asshole. Megan wanted to tell her that was enough, but her mouth was full and her hands were on Lilac’s hips trying to manage the gigantic cock that was being shoved down her throat. The meat stick was about seven inches in and Lilac was slowly but inexorably shoving more down there. Megan tried to push back and slow the gigantic cock’s penetration of her maw, but Lilac just used both hands and forced Megan’s head further down her pulsating meat.

Misty now had four fingers into Megan’s ass and was trying to get her thumb in as well. Megan wasn’t sure she was ready to have her ass fisted, she had started that afternoon as an anal virgin. But Lilac wasn’t giving in, and Misty wasn’t giving up.

Lilac had ten shitty inches down Megan’s throat, and Misty had the fat part of her hand pushing hard against Megan’s sphincter. The pressure on the back of her throat was becoming too much, and when Lilac’s shitty balls pressed against her chin, that was all she could take.

Megan’s stomach churned, retched, and then ejected a thick load of shit puke. Because her throat and mouth were already full, the foul mess rocketed out her nose and around the meat in her throat. The convulsion of her body as she vomited caused her asshole to pulse and Misty’s entire hand slipped inside up to her wrist.

Megan wanted to come and scream all at once. Lilac pulled out and Megan shook and vomited, coating her tits with foul shitty puke. Lilac knelt down and began licking the shit vomit from Megan’s big, firm tits. With each retch that Megan gave, her asshole pulsed, and Misty’s fist slipped deeper into her bowels.

Megan barely held on to consciousness as she retched and puked and coated Lilac’s face and body with her shit vomit. Her aunt was impossibly pushing her fist and arm deeper and deeper into Megan’s recently-virgin asshole. This was so disgusting, so ridiculous, but so fucking hot. The pressure inside her asshole only made her vomit harder and harder, and the horse shit mixture that her grandmother had filled up her asshole with was sluicing out around her aunt’s arm. Some of the shit was running down the inside of her thighs and some was running down Misty’s arm and dropping off the elbow into a shit pile on the lounge.

Mommy, who had been watching this, knelt down and began nibbling on the shit pile.

Megan’s scat puking slowed, and Misty slid her shit-covered arm out of Megan’s now-destroyed asshole. She now had several inches of shitty prolapse hanging out her asshole and the simple feel of it, along with her still-pulsating tummy drove her to an additional orgasm before she slipped down off the shit-stained lounge and lay out on the patio.

“Oh, fuck, ” she murmured. “I think I’m spent.”

Mommy dove in and was eating the pile of shit on the lounge, and Misty was back on all fours with still-ejaculating Lilac reaming out her shitty asshole. Megan closed her eyes. This evening had just been too much. She needed a break. She crawled over to another lounge and pulled herself up, laying back and just watching. Mommy and Misty were now swapping a sisterly mouthful of shit as Lilac did things to Misty’s asshole that a girl just didn’t do to her mother – even if that girl had a nearly footlong schlong.

Lilac looked over at Megan. “For all that bravado, you still haven’t felt my cock in your shitter, ”

“Don’t I get a break?” Megan asked.

Lilac ripped her cock out of her mother’s asshole, stepped to Megan and grabbed her hair.

“Not until you take all 11 inches up your ass.”

Megan thought about fighting, but then shrugged. After what Misty had done to her asshole with her entire forearm, a footlong cock wouldn’t be much of a challenge. Lilac wrenched Megan’s newly-gaped asshole open, dumped some lube in, and slid her cock inside.

Not surprisingly, her asshole yielded readily, taking the gargantuan meat. Inch after inch of Lilac’s shit-coated girl-meat slid into Megan’s stretched ass. Shit sluiced out, running down Megan’s thighs and across her cunt that was gaping wide and slightly prolapsed from the pressure of the giant cock in her ass. The sensation was amazing. Lilac pushed all the way in, then set up a steady pace, sliding her cock in and out of Megan’s anus.

Megan was reaching her limits of what she could take without a break. She needed to pause, but instead Lilac relentlessly tore into her ass, splattering her and Megan with more shit.

But Megan finally reached her limit when Mommy reached down and slid a finger into her slightly prolapsed cervix. Megan came hard and slowly slipped from consciousness.

Just exactly how long she was out, she wasn’t sure, but she came away laying on a lounge. She slowly opened her eyes. Suddenly she felt a splat of something warm, soft, and wet land on her bare stomach. This was followed by giggling.

It was dark and the back light was on, illuminating the patio. Her mother, grandmother, cousin, and aunt were lounging around on the patio sipping wine, all of them naked and covered in varying amounts of shit. The giggling came from behind Megan. She turned.

The neighbors next door – a Dutch family consisting of a blonde mother and two blonde college-aged daughters, were on their deck. The curvy mother with big, fat, saggy tits that looked like someone had filled two huge water balloons and tacked them loosely to her chest, Cornelia, was naked and bent over, her cheeks pulled open and her shitty asshole gaping wide. Her slender, barely-developed 18-year-old daughter, Beatrix, was dressed in a sundress and leaning over the railing, laughing. Cornelia’s older, curvier, daughter Vera, had her hand and forearm covered in her mother’s shit and clearly had just pulled an entire handful out straight from the tap and thrown it at Megan.

Megan laughed. “Nice shot, ” she said, pulling the poop patty from her stomach and taking a bite. “Nice consistency. My mother warned me you might be joining in.”

“It’s Beatrix’s first time too, ” Cornelia said, turning back around to face Megan and her family and leaning against the deck’s rail, her big saggy titties piling up atop the railing. “The horse shit pile over at the track is eight feet high, and I have a key. Who’s up for a road trip?”

“I’m in!” Megan cheered.
