Finn and his sister Jessy were sitting at the dinner table, together with their mother Joelle. They were having dinner together, but unbeknownst to their mother, the siblings got done fooling around in the bathroom just before. Finn's dick was still somewhat sticky after it had spent a good part of today inside of his sister's rectum. They were silently eating their meals, the only noises were their stomachs, still complaining about the unknown substance it was digesting.

Jessy had to supress multiple burps during their dinner and could not help but giggle when a more powerful belch suddenly escaped her mouth. The dining hall was suddenly filled with a vile dirty air that reeked of horse shit, Finn's face flushing red immediately as he felt blood rush to his loins. His dick had woken up, and he tried to control himself while staring at his food. Their mother Joelle was shocked.

"Jessy! Again with the burping! Your breath still smells like shit! What in heaven's name have you been up to today?" She eyed her daughter suspiciously. Finn wished he could turn invisible, but Jessy met her mother's gaze defiantly.

Suddenly, a small toot broke the silence. Joelle shifted uncomfortably on her seat, and the smell of a strong horse fart mingled with the residing air of dung. Jessy's eyes widened in amazement, while Finn's dick was rock hard by now. Joelle's cheeks went pink.

"Mom! You just farted! Admit it!" Jessy giggled. She sniffed the air hard, trying to detect all of her mother's flatulence.

"Ew it stinks! You stink just like I do!"

Joelle's eyes flashed with anger.

"Hold you tongue young girl! I will not allow any ... "

*ffffFRRFFRRFBBLBLlbb*

Another fart had escaped her rump that made her chair tremble. Her face strained, and she started to pant. Jessy was laughing hard now, while still inhaling the strong aroma her mother was releasing. Finn's nose was twitching as well, his nostrils filling with the putrid air that made his mind race.

"Stop laughing! I must have some... ooh my god!" Joelle was standing and bent over the dinner table by now. Another thunderous fart flew out of her butt, making her apron fluttering in the strong winds.

"Excuse me for a moment..." Joelle panted as she quickly exited the room, hurrying to the bathroom. Finn could still hear her toots down the hallway.

Jessy was on the edge of her seat, giving her brother a sneaky look. Finn now realized she was playing with herself under the table, obviously aroused by their mother's accident.

"So big bro. What do you say, should we follow her, see what that big booty has to offer?" she asked slyly and gave him a wink. Finn was perplexed, but his dick seemed to scream only one answer.

"I... " he stammered, but his sister was already on her way and skipping towards their bathroom where she could still hear their mother's trumpeting sounds. Finn quickly ran after her, his heart racing with excitement. He had been sneaking looks at his mother's big ass and getting aroused these last few months, and he figured his sister must have had the same feelings.

When he reached the bathroom door, Jessy was already peaking through the key hole. One hand inside of her panties, she was panting as she seemed to be in a lot of heat. Finn slowly approached, trying to make no sound that would give them away. When he reached his sister, he tried to get a peak at their mother. He glimpsed her, only seeing her lower thighs, muscular and quivering. He could hear her still thunderous farts, and the familiar smell of female horse flatulence crept in his nose.

Jessy was shoving him out of the way. "Move it, I was here first!" she hissed. Finn tried to push her away, not wanting to miss the show. "Get off me, I want to see her too!"

They were shoving and pushing, until suddenly the door burst open and they flew onto the white tiles of the spacious bathroom. In her hurry, Joelle must have forgotten to lock the door, so that it was standing wide open now, with the two siblings sprawled on the floor. They looked up. They lay right in front of their mother, who was still sitting on the toilet, a face of horror and shock painted on her beautiful mature face.

Nobody said anything. The silence was unbearable, the three of them just staring at each other. Suddenly, another cute little fart sneaked out of Joelle's clenched asshole. It was amplified by the porcelain thrown she was sitting on, the whole room was already smelling deliciously disgusting. Besides Finn, Jessy could not supress a faint moan. Joelle gave her a startled look that wandered down between her legs. Her panties were exposed, and a wet patch had already formed, displaying her obvious arousal.

Joelle only raised one eyebrow, looked her daughter dead in the eye and let out an ear splitting thunderous fart, making the toilet bowl vibrate in the process. Her face remained composed, as she was pushing out the hot putrid air, so that it made as much noise as possible. A wave of disgusting vile smells assaulted Finn's nose, and his dick was twitching again, luring him towards the source of the dirty smell.

Jessy's eyes were glistening. She seemed as if in a trance, a small drop of drool hanging on her chin, eyes fixed on her mother. She slowly crept forward.

Joelle was now starting to unload herself, and they could hear the sweet spluttering sounds of shit hitting the inside of the toilet bowl. The smell was almost unbearable by now, and the mother was still staring down Jessy with one eyebrow raised. The siblings were both attracted by the noises and smells, and were slowly inching forward, before they were only a short distance apart from their sharting mother. Joelle sighed.

"I never knew the past would catch up to me like that. Oh well, I guess it's true when they say the apple does not fall far from the tree.", she cooed, and slowly raised her big behind. She seemed to be about done now, and Finn peeked over to see the toilet bowl filled to the brim with soft brown shit. It emitted a strong smell that made his stomach churn, and he took out his dick, slowly wanking away. Joelle looked at their children kneeling in front of them.

Jessy was masturbating like in a trance, her eyes fixed on her mother's dung, and Finn was joining her, panting louder, letting himself get completely carried away by the sexual feelings he was experiencing.

Joelle shook her head. "You two naughty pigs you. Who's gonna clean me up?" She turned around and spread her rump, revealing a brown stained butthole. Finn was in awe at the sight of her mother's big dark pulsating donut, and he moved closer to get a good sniff. His eyes rolled back at the stink, but before he could taste the delicious looking pucker, his sister had jumped forward and dragged her long tongue across her mother's asshole. She planted her lips on the hole, sucking in an effort to get the sweet taste of the remaining shit out of her mother's rectum. She was rewarded with a fart that travelled straight down her throat, with little specs of manure following them. She coughed and pulled back. Their mother let out a deep moan and pushed her hips backwards, so that both her children could worship her dirty ass.

"Oooh yes, I have not felt anything like that for years!" she whispered to herself. After a while, her donut was squeaky clean, all traces of shit removed by her loving children.

Finn stood up, his raging dick in his hand. Jessy was still fingering herself furiously, and Joelle gave her son a loving look. "What are you going to do now, big stud?" she asked softly. Finn knew what to do.

He gently pushed her mother forward, until she was on all fours, hips raised high in the air. His big knob was placed at the entrance of her moist lips, and he slowly pushed until he was deep inside of his mother. The feeling of her pussy was heavenly, and Finn almost thought his knees would give way. He slowly started to pump, driving his knob lovingly into her mother's womb.

Jessy moaned in jealousy and moved over to her mother. She stood over her, her pussy right above her mother's butt, and bent forward. Finn now had two beautiful mare asses right in front of him, ready for the taking. He inserted two fingers into her sister's pussy, enjoying the soft warm feeling of her twitching inner walls, his strong fingers exploring the wet cavern while still fucking his mother. Jessy jumped at the intrusion and started grinding her hips on his hand.

Female moans were echoing on the bathroom halls, sounding like an angel's choir to Finn's ears. The feeling of fucking his mother and sister at the same time was exhilarating, and he grabbed their asses with his free hand, slowly and caringly pulling their buttholes apart in turn.

His sister's tight butthole had a pink taint to it, making it look as cute as ever, and Finn slowly inserted first one, then two fingers inside her rectum. The warmth that greeted him was familiar and comfortable, and he heard Jessy grunt with pleasure at the double penetration she was receiving.

His mother's round dark donut was bigger than his sister's and did not look as tight, but almost more delicious. The dark thick skin was wrinkled and still wet from its previous treatment, and the young stallion had to try it out for himself. He plunged back deep inside his mother's lust cavern, before pulling out completely and raising his wet and glistening dick to her backdoor entrance. Joelle pushed back, impaling herself on her son's huge dick, the strong dark pucker parting and engulfing his girth. He could hear a sharp intake of breath, superseded by even deeper moans.

Joelle herself was in nirvana. It had been ages since she had sex, and even longer since it had been as raunchy as today. She could have never imagined it would be her own children making her feel this way. She did not think about how wrong it was, only about how right it felt. Her whole body was tingling and filled with energy, her toned butt glistening with sweat, and she could feel her daughter on top of her, her pussy juices dripping down her ass crack, towards her son's dick that was impaling her poor longing butthole and rectum.

Finn loved the feeling of his mother's intestinal walls caressing and treating his dick, and as he pumped away, the dark pucker opening and closing around it, he was almost disappointed that his dick was almost not soiled at all. His mother's rectum must have been cleaned good, so he pulled out his fingers out of Jessy's pink asshole. He could see traces of brown on them and had an idea.

Pulling out all of his fingers and his dick, he positioned his member at Jessy's backdoor entrance. He slowly pushed, the tight asshole accepting his girth reluctantly. Once he was in completely, he could hear his sister pant loudly. He pulled out his dick in one swift motion, making her wince in surprise. His dick was specked with smears of dung and shit, just what Finn had hoped to see. He plunged it back inside of his mother's asshole, making her gasp in surprise.

He continued his alternating thrusts, making sure to always insert fingers into the other cavities. This way, he fucked his mother and his sister in all of their orifices, until his dick had been soiled thoroughly and their pussies looked just as brown as their buttholes.

Feeling her son's soiled dick smear her pussy with shit and her rectum with love juices, Joelle started to buck and twitch in ecstasy. She could still not believe her kids were just as nasty as she used to be. She grinned as she felt her daughter moan and neigh with every trust Finn gave her. Jessy was orgasming now, releasing a strong torrent of squirting juices that ran down her mother's back and ass.

Finn plunged his dick deep inside Jessy's asshole when he felt the gushing sensation of his sperm being ejaculated, filling her up with his seed, his balls twitching in an effort to shoot as much of their content inside of his sister's warm dirty rectum. A few minutes passed, as they were all twitching and groaning, before they slowly calmed down.

Finn's dick became flaccid, still inside his sister. He could feel the pressure of his bladder, unnoticed until now, and had a wicked idea. As Joelle was already getting up from under her daughter, Finn hold his sister in place and started to release a stream of urine that was flowing right into his sister's ass, giving her a golden enema. She gasped at the feeling of being filled up, warm liquid gushing down her intestines with the already copious amount of spunk inside of her. The pressure became to much, and she almost exploded in a torrent of golden piss, white cum and brown turds that were catapulted right back at Finn's lower abdomen. His dick had been pushed out as well, completely soiled and wet as more liquid and solid brown stinking matter hit him.

Joelle was observing this spectacle with one hand toying with her moist brown pussy.

"Jessy I never knew you were such a dirty slut!" she exclaimed, "I love it!"

Her daughter giggled, releasing the final turd with a wet fart, and turned around to admire her work. Finn was standing in a pool of urine and cum, completely drenched, with turds clinging to his loins.

The mother keeled down in front of her soiled son, picked up some turds and smeared them on his still flaccid dick. She beckoned Jessy over to her.

"Show me how dirty you are and get behind your brother", she instructed. The young mare followed, and Finn soon felt her hands caressing his buttocks, before they pulled them apart and a hungry tongue was lapping at his asshole. His mother had now started to lick and suck his shit covered dick, and the combined feeling of his sister's tongue with his mother's expert mouth made him rock hard in seconds. He looked down at her.

She was deepthroating his soiled dick, brown drool dripping down her chin, her eyes fixed on his. They looked loving and caring, with a hint of sexual longing in them. Finn felt warm and excited, seeing his mother engulf his dick with care and love. He shoved his dick deeper down her throat, making her heave and gag, her eyes started to water and roll backward. The feeling was incredible, and he started to completely relax his whole body.

His sister was greeted by a strong taste, as she pulled her tongue back to see her brother's cute butthole had started to release his filling. Joelle noticed what was going on and pulled back.

"Show me how you can eat it all my love, don't spill any of your brother's shit, swallow it all!" she instructed her daughter, and Jessy obliged. She positioned her open raw right underneath Finn's shitting asshole, as his horse dung was slowly pushed right into her waiting mouth. She started to swallow, her mouth still open, not wanting to stop the brown stream of shit flowing out of her brother. The turds tasted disgusting and she heaved and gagged audibly, focusing all her energy on keeping everything down.

After a short while, Finn's backside was done releasing its contents, and Jessy closed her mouth to savour and chew the last turds. She moved back to her mother, who was still sucking her son's raging dick. Jessy opened her mouth, revealing a putrid sight of greenish brown dung caking her teeth, clinging to her braces as she loudly slurped and chewed the strong and putrid shit. Her tongue was slushing around in the toxic waste to give her brother a disgusting display of her newfound love for his shit. Her tastebuds were firing all at once, making the taste the bitter earthy aromas push her arousal into overdrive. She closed her eyes and mouth and started to swallow the vile sewer like contents.

Finn and Joelle could see her struggle with the load, and her stomach lurched and churned. The young mare closed her eyes and contorted her face, looking like she was about to throw up. She eventually got it all down and beamed proudly at her mother, displaying an empty mouth with a long stinking tongue, her cute braces defiled by the brown bowel movement she had just eagerly gulped down.

Just a second later however, she contorted her face again and a small bubble of green brown mushy shit came back up, filling her mouth and running down her chin before she could close it again. She shyly looked at her mother, who grinned and started to lovingly lick away the traces of liquid shit that were dripping down her daughter's maw before inserting her tongue into Jessy's filled mouth, lip-locking to let no more manure escape their loving embrace, swapping around the putrid contents, experiencing the taste of her own son's shit. They shared the dirty load, both swallowing down half of it. Finn could hear an audible *gulp* and see the bulge travelling down their throat, before they released their lip-lock and the intense loving kiss.

"Damn mom, you are a shit whore!", Jessy exclaimed in excitement.

Her mother burped in response and they all laughed.

"I have had my fair share of filth back in the day honey", Joelle cooed and grinned.

Finn meanwhile had observed the whole spectacle while vigorously wanking his wet and hard member, enjoying everything the two shit stained stinking mares had just done. They beamed up at him, their brown soiled faces filled with happiness, and Finn could no longer keep himself from orgasming and released his second load all over them

He was first filling his mother's open maw, shooting his sperm into it until it was completely full, before moving over to his sister's brown muzzle. Joelle swallowed the seed of her son, nostalgically savouring the taste of horse sperm, and looked at her daughter do the same. Finn was not done yet however and moved back to his mother to give her some more of his seed.

Joelle took his ejaculating dick and placed the knob right on her left big nostril. The sight was incredibly wicked as Finn's final loads of cum went right into her nose and sinuses. Joelle neighed, her eyes rolling to the back of her head, positively snorting the white musky spunk her son was shooting up her nasal cavity. Her children stared at her in awe as the strong smelling cum was flowing down to her tonsils and down her throat as well as dripping out of her big nostril. Jessy took her mother's face in both hands and her brown tongue darted out into her mother's nose, trying to extract as much sperm as she could fine. Joelle pulled up her nose with a snorting sound and spat the last remnants of cum in her daughters waiting mouth, covering her brown dry tongue with white slime.

After they had swallowed everything they could, the tree of them stepped into the shower to clean themselves of the filth and shit that was staining almost every inch of their body. They lovingly caressed each other and shared more kisses, when Jessy suddenly asked:

"Mom, what do you mean when you said you had your fair share of filth back in the day?"

Joelle smiled and gave her a kiss on the forehead. CLet's just say I was an eager foal back in the day. And I think it is time to revive my old habits.", she ominously explained.
