(This begins immediately after the third part, “Mommy Teaches Megan About Scat – Part 4”. And remember, this is a fantasy – do not do this! Really!)

The horse track was just far enough away that they didn’t feel like walking. And despite being a pack of incestuous scat-loving lesbians, they weren’t hot on the whole idea of getting the insides of their cars shitty. So a round of showers ensued, and they all squeezed back into their less-than-virtuous outfits. They piled into three cars and made the drive to the darkened horse track.

The paddocks were around back, and the only person onsite was a groundskeeper who was dead drunk and asleep in his quarters. So nobody was there to stop them when Cornelia unlocked the gate, let them drive in, then locked it behind them. Just to be 100% safe, she slid a pair of hundreds under the groundskeeper’s door.

“He’ll know what it’s about, ” she said with a wink.

They drove around to the very back of the paddock and parked. Climbing out of her mom’s SUV, Megan gasped.

In front of them was a pile of horse shit that was at least eight feet high, but probably more like ten. The smell was overwhelming, and with the breeze blowing from the other side of the pile, they had more than their fill of horse shit fragrance.

Next to the horse shit pile was a spigot and a hose. Cornelia peeled out of her tank and tights, her huge fat, saggy tits hanging down to her waist, and grabbed the hose. She sprayed down the pile of horse shit, softening it up and sending rivulets of manure water drifting across the concrete.

“Good times!” she called and stepped over to the now-slick pile of horse shit, grabbing a handful and shoving it in her mouth. “That’s some fine horse poo, ” she added around a full mouth.

Megan peeled off her outfit, as the other women were doing, and gingerly approached the pile of horse shit. She reached out and took a handful, pulling it to her mouth and licking the nastiness coating her hand. It was nice. The horse shit mixture her grandmother had made was nice, but the raw thing was even better. She shoved a handful of horse shit into her asshole, then another. As nice as her grandmother’s mixture had been, real shit was so much nicer. She pushed two more handful’s up her ass, then let her prolapse hang out again.

She felt a pair of hands run up her stomach and a slender body press against her side. It was Beatrix.

“I hear it’s your first time, too, ” she said, softly.

“It was, but my mother has broken me in pretty firmly, ” Megan replied. She turned around and bent over slightly, reaching back and sliding four fingers into her loose asshole.

“I’ve already wrecked my asshole, ” Beatrix said, turning around and showing Megan her ass. She was right, she was only 18, but her sphincter was barely staying closed. “But I’m still not sure about this shit thing.”

“My first taste of shit was my mother’s, and it was amazing, ” Megan said, turning back to Beatrix.. The two girls turned to Beatrix’s mother, who was now leaning against the manure pile, rubbing horse shit into her skin. She caught Beatrix and Megan looking.

“Megan says I should start by eating your shit, mother, ” Beatrix said to Cornelia.

“That’s the best way to start, ” Megan’s mommy Elise said. Cornelia turned and leaned forward against the shit pile, her fat titties and shoulders pressing against it. She reached around with both hands and wrenched her asshole open, revealing loads of shit and pink assflesh.

“Are you ready, baby?” Cornelia asked her daughter.

“I don’t know, ” Beatrix replied.

“I wasn't sure either at first, ” Megan said. “It’s okay, let’s do this together.”

Megan knelt down behind Cornelia’s gaping asshole and gestured for Beatrix to join her. Cornelia gave a push and her pink assflesh tumbled out of her yawning asshole, hanging out inches from her daughter’s virgin face. Beatrix gulped.

“It’s okay, ” Megan crooned. “Watch.”

Megan ran her tongue around the thick shitty flesh, scooping up a pile of shit then pulling it into her mouth. She rolled the poop around in her mouth for a moment, then swallowed. She loaded up her tongue again and pulled it into her mouth, but this time didn’t swallow. Instead, she leaned forward to Beatrix, pulling her towards a kiss.

Cornelia’s 18-yo daughter hesitated, looking at the mouthful of her own mother’s shit that was begging for a kiss.

She hesitated.

“When my mother told me about this I was interested in trying it, ” Beatrix said. “But now I’m not sure. I mean, I love anal and all that, but scat...I don’t know.”

Cornelia looked back over her shoulder at her daughter. “Remember our deal. You have to try it once.”

“But...”

“Just one mouthful.”

Beatrix was continuing to hesitate. “I...I can’t.”

“Oh for fuck’s sake, ” Megan finally said, exasperated. She pushed her face into Beatrix’s, kissed her, and shoved a load of shit from her own mouth into Beatrix’s.

Beatrix pulled back hard and gagged – coughing and spitting out the shit that had just been shoved into her mouth. She reached back like she was about to slap Megan, but her mother grabbed her arm and pulled it behind her back, pinning it. Beatrix let out a yelp.

“You...you bitches!” she spat. “This is disgusting.”

Lilac appeared in front of her, holding a mouth guard gag.

“What’s that?” Beatrix challenged her.

Cornelia pulled her daughter’s hair back and Celeste pinned her arms behind her back. Beatrix tried to fight and kick, but couldn’t break free. Lilac forced the mouth guard gag into her mouth and secured it behind her. Beatrix’s mouth was now held wide open.

Megan pushed Beatrix down on her knees. “Let’s give this bitch a taste of her mother’s shit the right way, on Lilac’s cock.” Cornelia bent down next to the pile of horse shit and pulled her ass cheek’s apart. Lilac stroked her cock that was now purple and pulsating and was so engorged it was at least a foot long and thick around as a fist. She drove the entire thing into Cornelia’s shitty, prolapsed, destroyed asshole.

Cornelia gripped the shit pile as Lilac pushed her immense meatstick into her yawning shitter. Inch after inch drove inside until even Lilac’s balls were knotted inside Beatrix’s mother’s hole. Beatrix’s curvier sister, Vera, moved over next to her mother and pulled apart her asshole, pushing out her own mountain prolapse coated in scat.

“Add my own shit to your cock too before you give my sister a taste, ” Vera said.

Lilac smiled and ripped her pulsating, poo-covered cock from Cornelia’s ass and rammed it into Vera’s asshole even as Cornelia leaned over and began licking the horse shit from Vera’s big young tits. Vera moaned as Lilac knotted her, giving several hard strokes that made her ass quiver before pulling out and moving over in front of Beatrix, who was now being held down by Mommy and Grandma Celeste. Lilac grabbed Beatrix’s hair and began sliding her shit-covered cock into her mouth that was still being forced open by the gag. Beatrix tried to pull back but Lilac was too strong and forced her cock into her mouth.

Beatrix moaned and cried, tears streaming down her face, but Lilac held her tight, forcing inch after inch of shit-coated cock inside, pushing reams of scat down her throat. She moaned again and tried to say something around the thick cock that was driving deeper and deeper into her gullet.

“What do you think she is saying?” Celeste asked.

“I think she is asking her mommy and sister to fist her shitty asshole while Lilac fucks her mouth.”

Beatrix’s reaction clearly indicated that wasn’t what she wanted, but that didn’t stop Vera and Cornelia from pulling her rear up onto her knees and tugging her cheeks apart. Beatrix’s young asshole was clearly no stranger to abuse, the sphincter was thick and long. And as Lilac started setting up a steady motion destroying Beatrix’s shit-filled throat, Vera dumped a load of lube into her barely-legal sister’s asshole and slid her fist inside.

Despite her protests, it was clear that Beatrix hadn’t tried to get clean before today’s shit sex party, because Vera immediately encountered a soft bolus of shit inside Beatrix’s asshole. She grabbed a handful and pulled it out, licking her fingers then rubbing the shit across her own, big, pendulous tits. Her mother reached in and slid her own arm into Beatrix’s asshole, then Vera joined her, double-fisting Beatrix’s asshole that was now pushing out a load of shit around their arm.

“Why, I think my little baby daughter is getting into this, ” Cornelia said, pushing her arm in all the way to her elbow.

Lilac slid her cock out of Beatrix’s mouth and removed the gag.

“Please, ” Beatrix moaned. “Please feed me more shit then fuck my mouth and ass some more. Please, I’m ready to be a good little shit whore. Thank you for introducing me to my true shit whore self.”

Vera stood up and moved in front of her sister, leaving her mother to revert to using both arms to satisfy her baby sister’s insatiable shitter, pushing them in past the elbow. Vera bent over and pulled apart her cheeks in front of Beatrix, pushing out her asshole in a thick shitty prolapse that ejected a big soft load of shit.

Beatrix ate it up, gulping down load after load of shit, then when she had ingested all of her sister’s shit, she reached for a handful of horse shit and shoved it down her throat, then a second handful, then a third. Her slender, barely-developed body bulged full of shit. She then reached for Lilac’s cock and drove her mouth all the way until her chin hit Lilac’s sack, taking a foot of thick meat down her throat. Beatrix coughed, gagged, then ejected a thick load of shit vomit around the cock, spraying Lilac and herself with puke and shit.

It was amazing. Megan and Mommy were sitting to the side, masturbating while they watched Beatrix have her shit coming-out party. She had become the perfect little shit whore slut, and was now eating and puking shit like a pro.

Mommy tapped Megan on the shoulder and crawled across the tarmac to a large manhole set to the side.

“What’s this?” Megan asked. The top of the manhole read “Sewer”.

“It’s the entrance to our secret little clubhouse. We have some pets down here. Do you know what a Scatapus is?”

“A what?”

“A Scatapus. It’s a sort of shit-loving squid that love to hang out in sewers. Like octopuses the have a penchant for human women, and we keep a bunch of them as pets, just specifically for nights like this. You’ll love it...”
