Ryan had grown up in the council house on the rough edge of Manchester like it was normal. The place always smelled of fried food gone cold, cheap cigarettes, and the thick, sour musk that clung to his mum no matter how often she “showered.” She never really cleaned herself properly. She’d stand under the water, legs apart, and just let it run while she pushed her shit out standing up. No squat needed. Her arse was so flat, her cheeks nonexistent, that her shithole sat right there between them, pinkish-brown and always slightly parted, like it was permanently ready to drop another load. She’d grunt, push, and the turds would plop straight into the drain while she washed her hair with the same hand she’d just wiped with.

Derek, his dad, had loved every filthy second of it.

He’d found her when she was already a born degenerate — big soft belly that hung low over her cunt, tiny tits that barely filled a hand, no arse to speak of, slim hips, and those broad shoulders that made her look stocky and crude. Her face was the sort other people called ugly: piggish nose, small squinty eyes, thick lips that never quite closed over an overbite, and a permanent sheen of oil on her coarse, thick, dark hair. She swore like a docker, ate with her fingers, burped loud and long, farted without shame, and Derek had got a perverse thrill from all of it. He’d married her anyway. Paid the bills. Kept her in the council house. Let her be exactly the disgusting creature she was.

When she got pregnant with Ryan she’d shrugged. Derek had been over the moon.

Derek dropped dead of a heart attack when Ryan was nineteen. Left them the house and a decent payout. Ryan was twenty-four now, and the money was mostly gone on takeaways, booze, and whatever else his mum fancied. He didn’t care. He’d spent his whole life watching her. Where other lads would’ve been sickened, something in Ryan had twisted the opposite way. He craved it. The heavy sway of her gut when she walked. The way her shithole winked when she bent over to pick something up, the dark pucker visible because there were no cheeks to hide it. The smell of her unwashed cunt and arse when she sat on the sofa in nothing but a stained nightie. He’d grown up hard for it. He took after her completely — a natural degenerate.

That morning the kitchen smelled of bacon fat and yesterday’s farts. His mum was at the cooker, back to him, wearing nothing but a threadbare pair of knickers that had ridden right up her crack. The thin cotton was swallowed between her flat cheeks, leaving her arsehole completely exposed — a dark, wrinkled ring that flexed slightly every time she shifted her weight. Her big belly hung forward, resting against the worktop. Her coarse black hair was greasy at the roots, hanging in thick ropes down her back.

Ryan came up behind her quiet as anything. For a laugh — or maybe because the urge had been building for years — he hooked two fingers into the waistband of her knickers, pulled them aside, and slid his middle finger straight into her arsehole.

It went in easy. No resistance. Her hole was loose from years of standing shits and never wiping properly. Warm, soft, and already a bit tacky. He felt the first knuckle sink in, then the heat of her guts gripping him.

She barked out a laugh, loud and ugly. “Oi, you cheeky cunt! Get your finger out my arse and sit down for breakfast.”

Ryan didn’t move. Instead he pushed deeper, then worked his ring finger in alongside the middle one. Two thick fingers now, buried to the second knuckle in his mum’s shithole. He could feel the soft, yielding walls inside her, the faint pulse of her body around him.

She laughed again, a wet, phlegmy sound. “Fucking hell, Ryan. Two fingers now? You’re as bad as your dad was.”

Then she pushed.

A wet, rumbling fart ripped out around his fingers. Hot air and the thick, rotten-egg stench of her bowels blasted against his knuckles. It was long and bubbling, the kind that spoke of last night’s curry still working its way through. The smell hit him full in the face — rich, acrid, unmistakably hers. He laughed, pulled his fingers free with a soft, wet sound, and stepped back.

His mum turned, still chuckling, her small eyes crinkling. She didn’t pull her knickers back into place. Her arsehole stayed on show, glistening slightly, a faint smear of brown on the rim.

Ryan sat at the little kitchen table, lifted his fingers to his nose, and inhaled deeply. The smell was concentrated there — her arse, her shit, the inside of her. He breathed it in like it was perfume, eyes half-lidded, cock already thickening in his trackies.

She plated up bacon, eggs, and fried bread, the grease popping. Her big belly swayed as she moved. When she set the plate in front of him she paused, watching him still huffing his fingers.

“Proper little pervert, ain’t ya?” she said, voice fond and rough. “Just like your old man. He used to do the same thing — stick his fingers up there then sniff ‘em all through breakfast. Made him rock hard every time.”

Ryan didn’t answer. He just kept smelling his fingers, then licked one clean with a slow, deliberate drag of his tongue. The taste was bitter, earthy, unmistakably arse. He swallowed it down and went back to sniffing.

His mum sat opposite, legs spread wide under the table so her exposed hole was still visible if he leaned forward. She ate with her fingers, shoving bacon into her mouth, grease shining on her thick lips. She burped loudly, then let out another short fart that rattled the chair.

They ate in comfortable silence for a while, the only sounds the wet chewing, the occasional belch, and Ryan’s steady, deep inhales of his own fingers.

When the plates were empty she leaned back, one hand rubbing her gut, the other scratching lazily at her cunt through the thin knickers.

“If you want some more,” she said, casual as anything, “you know where to find it. Arse is right there. Cunt’s not far off either. Been a while since anyone’s had their face buried in it proper. Your dad used to spend hours down there, nose in my shithole while I pushed farts into his mouth.”

She stood up, turned, and bent over the sink to rinse the plates. Her knickers were still pulled aside. Her arsehole winked at him again — dark, loose, inviting.

Ryan’s cock was fully hard now, straining against his trackies. He could still smell her on his fingers. The kitchen reeked of her farts and bacon and unwashed cunt.

He stood up slowly.

His mum didn’t turn around. She just gave her arse a little wiggle, the flat cheeks barely moving, that exposed shithole flexing like it knew what was coming.

“Door’s open, love,” she said over her shoulder, voice thick with amusement and something darker. “Come get it if you’re man enough.”

Ryan stepped forward.

Ryan stepped right up behind her at the sink. His trackies were already shoved down, his big hard dick springing out heavy and veiny, small tight testes drawn up underneath. His mum’s flat arse was still on full display, knickers yanked aside, her loose shithole winking and shiny from his fingers earlier.

She let out a long, loud, wet fart right then — a deep, rumbling blast that vibrated her flat cheeks and filled the kitchen with thick, rotten-egg stench. It went on for several seconds, bubbling and spluttering.

“Hurry the fuck up,” she grunted, voice strained. “I’ve got to shit, Ryan. Proper urgent now.”

He didn’t need telling twice. He grabbed her wide hips with one hand, lined his fat cockhead up with her exposed arsehole, and shoved forward rudely. Her hole gave way easily — loose and well-used from years of standing shits. His dick sank in to the root in one rough thrust, her warm, tacky guts swallowing him whole.

“Oh yeah…” she groaned, low and filthy, pushing back against him. “That’s it, love. Fuck your mum’s arse.”

Ryan started banging away immediately. No finesse. Just hard, fast, sloppy thrusts into that easily accessible anus. The wet, squelching sounds filled the kitchen. Her big soft belly swung and slapped against the sink with every impact. He could feel her guts clenching and fluttering around his cock, still full of shit she was holding in.

It didn’t take long. The smell of her fresh fart still thick in the air, the sight of his dick disappearing into that dark, winking hole, the way her coarse greasy hair swung — it was too much. He slammed in deep, bit down hard on the back of her neck like an animal, and came with a strangled grunt. Thick pulses of cum flooded her arse.

She let him finish, then twisted her head. “That’s it. Get out my arse now. I’ve really got to shit.”

Ryan pulled out with a wet, messy sound. Cum and arse slime clung to his cock. His mum didn’t even pull her knickers up properly. She just waddled off toward the bathroom, one hand pressed to her gut, the other still holding her knickers aside so her shithole stayed visible, a trickle of his cum leaking out of it.

He followed her like a dog.

In the bathroom she stripped off what little she had on. Her tiny tits, the heavy hang of her belly, the complete lack of arse. She climbed straight into the shower tray, turned the water on lukewarm, and started soaping up. Her armpits were extremely hairy — thick, dark, wiry bushes that she scrubbed vigorously, lifting her arms high so the coarse hair foamed with suds.

Then she just let go.

Heavy logs of shit dropped from her exposed arsehole with wet, heavy plops, splattering against the shower floor and swirling toward the drain. Some broke apart, some stayed in thick coils. The smell was immediate and overpowering — fresh shit mixing with the steam. She didn’t even look embarrassed. She just kept soaping her hairy pits like it was the most normal thing in the world.

Ryan stood there watching, dick still half-hard and shiny with her arse and his own cum. He stripped off, stepped in behind her, and pulled the shower curtain closed. The small space filled with steam and the ripe smell of her shit.

He planted his feet, strained hard, and pushed out a huge, thick log of his own. It dropped heavily, coiling on the floor between their feet. He stood proudly afterward, chest out.

His mum turned, saw it, and laughed loud and genuine. “Fuckin’ hell, that’s a big one! Good lad. Proper chip off the old block.”

She pulled him into a hug right there under the running water. Their wet, shit-smeared bodies pressed together — her big belly squashing against him, his cum-slick cock trapped between them. Then they started making out, sloppy and rough. Tongues everywhere. She spat directly into his open mouth. He spat back into hers. They laughed through it, hands manhandling each other’s faces — thumbs hooked inside cheeks, stretching mouths open, fingers gripping jaws, spitting into each other’s eyes on purpose. Thick globs of spit landed on cheeks, ran down chins. They rubbed it in, laughing harder.

While they were still kissing and spitting, she reached around behind him. Her finger found his arsehole and slid straight in — no resistance, just like hers. Then a second finger joined it. She worked them in and out slowly while they kept spitting in each other’s faces.

“How’s that feel then?” she asked against his mouth, fingers buried knuckle-deep in her son’s arse.

“Love it,” Ryan groaned, and they both burst out laughing again.

They finished the shower like that — her fingers still lazily pumping his hole while they kissed and spat and groped. When the water finally ran clear she pulled her fingers out, brought them to her nose, and sniffed them deeply with a satisfied grunt.

She dried him off first with a rough towel, rubbing him down like he was still little. Then she grabbed the big bottle of cheap body lotion and started rubbing it into his skin, working from his shoulders down. Her hands were firm, familiar.

“Used to do this every night when you were a baby,” she said, voice soft but still rough. “Rub you all over after your bath. You’d just lie there cooing while I lotioned your little body.”

Her hands moved lower. She got to his cock and balls and didn’t hesitate.

“Didn’t have this back then though, did ya?” she said with a dirty little chuckle, squeezing lotion onto his dick and working it in with both hands. She stroked him slow and firm, rolling his small testes in her palm, thumb rubbing over the head. “Look at the size of this thing now. Proper man’s cock.”

Ryan stood there letting her do it, still damp from the shower. Without any warning his orgasm hit him hard. Thick ropes of semen suddenly glopped out of his dickhead in heavy pulses, splattering her hands and his own stomach.

She didn’t stop. She just used his own cum as extra lube and kept jerking him through it, working every last spasm out of him until he was twitching and oversensitive. When he finally stopped pulsing she lifted her messy fingers to her mouth and licked them clean, one by one, eyes on his.

“Right,” she said, wiping her hands on the towel. “Throw some clothes on. We’ve got visitors coming over in a bit.”

She turned and walked out of the bathroom naked, big belly swaying, flat arse and loose shithole still on show, leaving Ryan standing there in the steamy room with the smell of their shit still lingering in the drain.

Ryan threw on a pair of loose trackies and an old t-shirt, his cock still half-hard and obvious. His mum didn’t bother with much — just yanked her knickers back into place and pulled on a stained dressing gown that hung open over her big belly and flat arse. The smell of their shower shit still lingered faintly in the air when the doorbell went.

His grandmother walked straight in like she owned the place.

She was worse. Much worse. Huge sagging belly that strained against a faded floral dress. No real tits to speak of — just two flat, wrinkled flaps under the thin fabric. No arse at all, same as her daughter. Strong, wide shoulders and thick arms. Her face was lined and coarse, with a wiry grey-black mustache above her lip and a sparse, patchy beard growing along her jaw from whatever hormonal mess was going on inside her. Under that dress was a massive, untamed bush of pussy hair that you could see the edges of when she moved.

She hugged her daughter first — a big, crushing hug that squashed bellies together. Then she turned to Ryan.

“Alright, big man,” she said, voice gravelly. Her eyes dropped straight to the obvious bulge in his trackies. She reached out without hesitation and grabbed his cock through the fabric, giving it a firm squeeze. “What’s going on here then?”

Ryan laughed, hips twitching forward into her grip. “Thanks, Nan.”

She gave him another squeeze, then let go like it was nothing.

His mum stepped in close, lifted her mother’s arm, and shoved her face right into the armpit. She took a long, deep sniff.

“Fucking hell, Mum. It smells clean in here. What’s wrong with you?”

Grandma chuckled, low and rough. “Had to have a shower at least once this week, didn’t I? Couldn’t come round stinking the place out completely.”

The daughter pulled back, eyes narrowing. “Did you wash your cunt too?”

“Yeah,” Grandma said. “But I took a shit after and didn’t wipe. Couldn’t be arsed.”

Ryan’s mum didn’t even hesitate. She grabbed the hem of her mother’s dress and yanked it up around her waist. No knickers. Just a wild, thick thatch of grey-black pussy hair and, between flat cheeks, her arsehole — dark, wrinkled, and smeared with a sweaty brown mess. Dried shit clung to the hairs around it and streaked the crack.

“Fucking lovely,” his mum grinned, delighted. She stuck two fingers straight in, scooping through the mess, then pulled them out and sniffed them right in front of Ryan. “Still warm too.”

Ryan came around the other side. He didn’t need inviting. He pushed his own fingers into his grandmother’s dirty arsehole, working them in and out a couple of times before pulling them free and smelling them deeply. The thick, shitty scent hit him hard. He pushed them back in, playing with the loose ring while his mum did the same from the other side. Two sets of fingers stretching and probing their nan’s shithole while she stood there chuckling.

“This feels like Friday night,” Grandma said, laughing properly now. Instead of stopping them she just bent forward, braced both hands on the back of the couch, and stuck her arse out. “Go on then. Have at it.”

Ryan’s mum dropped straight to her knees behind her. She spread the flat cheeks with both hands and licked a long, slow stripe right over the filthy hole. Then she pushed her large, thick tongue inside, working it around in wide circles, tasting the mess her mother had left. She moaned into it, tongue-fucking the loose arsehole while her own big belly rested on the floor.

Ryan waited his turn, then took over. He licked too, but after a minute he pulled back with a complaint. “There’s fuck all left in there.”

Grandma reached back and patted his head without looking. “Wait till later, love. Plenty more where that came from.”

Ryan’s mum stood up, wiped her mouth on the back of her hand, and headed to the kitchen to put the kettle on. Ryan and his nan followed, the three of them ending up around the small kitchen table. His mum brought over three mugs of strong tea.

Ryan looked at his grandmother across the table. “Nan… why are we all so fucking degenerate?”

She took a long sip of tea, then set the mug down and looked him dead in the eye, proud as anything.

“Because your mother — my daughter — is the product of incest going back generations in this family. My dad and my uncle both knocked me up when I was younger. Your mum came from my dad. The one from my uncle was stillborn. We kept it in the family. Always have.”

She said it like she was telling him the weather.

“It’s a shame there’s no siblings left for you except your own mum,” she continued. “But if you try hard enough, you might be able to get a daughter or even an uncle out of it one day. Keep the line going proper.”

Ryan didn’t say anything. He just stood up, stepped over to his mum, and hugged her around the waist from the side. She was still standing by the counter. She rested one hand on top of his head, fingers stroking through his hair like it was the most natural thing in the world.

His mum looked at her own mother. “So why’d you come over today then?”

Grandma grinned, showing crooked teeth. “Figured the lad was getting to proper fucking age. And I wanted to suck a dick. It’s been forever since I had one in my mouth.”

She said it plain, then took another sip of tea like she hadn’t just announced she was there to blow her own grandson.

The three of them sat there in the kitchen, the smell of their earlier play still on their fingers, the kettle steaming on the side, and the understanding hanging thick in the air that this was only the beginning of the visit.

Ryan pushed his chair back and walked straight over to his nan. He dropped his trackies and boxers in one go, his big cock already half-hard again, and jabbed the fat head right into her face, smearing it across her wiry mustache and lips.

Grandma didn’t flinch. She popped her false teeth out with a wet click and set them on the table. Her mouth was suddenly soft and gummy. She opened wide and went straight to work, facefucking herself on his cock with zero hesitation. Her long, thick tongue slithered out and lapped greedily at his small tight balls while she forced her face down, taking him deeper.

Ryan grabbed her head with both hands, fingers sinking into her coarse grey hair. He played with her big, floppy ears, tugging and rubbing them while she gagged and spluttered around his dick. Thick strings of spit poured from the corners of her mouth, dripping onto her huge belly and the floor.

He looked over at his mum, who was still standing by the counter. “Her throat’s tighter than your arse, Mum.”

His nan made a wet, approving noise and went harder, slamming her face down until her nose was buried in his pubes. Violent, retching gags tore out of her — loud, ugly, choking sounds that filled the kitchen. Spit flew everywhere. She didn’t pull back once.

Ryan reached down with one hand and shoved it straight into her armpit. He dug his fingers into the thick, wiry hair there, fondling and tugging on the coarse bush while she kept throat-fucking herself on his cock.

Without any warning his orgasm hit. His cock jerked and started spitting thick, heavy gushes of cum straight down her throat — hot, incest-rich loads that made her choke hard. She spluttered violently, cum and spit bursting out around his shaft and running down her chin in thick globs.

She yanked her head back, his dripping cock sliding free with a wet pop. Cum and thick saliva poured from her gummy mouth. She coughed, laughed, and wiped her face with the back of her hand.

“Thanks for that, love,” she rasped, still chuckling.

Ryan grinned down at her. “No, thank you.”

They both laughed, proper and easy. She wiped the rest of the mess off her lips and chin, popped her false teeth back in, and gave his softening cock a fond little pat.

He stepped back, pulled his trackies up, and said, “Right, I’m off to school then.”

His mum set her tea down and smiled. “Not today you’re not. Surprise — you’re switched to home schooling from now on.”

Ryan blinked, then grinned wide. “Fuckin’ hell, that’s brilliant. Why though?”

She walked over and stood next to him, one hand resting on his shoulder. “Don’t want some other bitch out there stealing my baby boy, do I?”

He shrugged, completely fine with it. “Yeah, alright. Sounds good to me.”

Without another word he stripped off again right there in the kitchen — t-shirt, trackies, everything — until he was standing in just his boxers and a sleeveless vest. His cock was still shiny with his nan’s spit and cum.

His mum looked at him, then at her own mother, and broke into a big, happy smile. She stepped over and pulled her mum into a tight hug, bellies pressing together, both of them still smelling of armpits, arse, and fresh cum.


The following week, there was a knock at the door.

Ryan opened it in just his boxers and sleeveless vest, cock already half-hard from the constant state he’d been living in. Standing there was his girlfriend — the one he’d completely forgotten about for the last seven days.

She looked oddly similar to his mum in ways he’d never really clocked before. Same broad shoulders. Same coarse, thick, oily dark hair. Same complete lack of arse, flat chest, and that wild, untamed bush of pussy hair that always showed when she wore anything loose. He’d never questioned why he was drawn to her. He just went with it. Now it made a sick kind of sense.

She looked pissed off.

“Where the fuck have you been?” she demanded, pushing past him into the house. “I’ve been calling you all week. You just disappeared. What the hell is going on?”

Ryan was still processing the shock of seeing her when his mum appeared from the kitchen, big belly swaying under an open dressing gown, bare arse and loose shithole on full display.

“That’s your girlfriend?” his mum asked, voice flat.

“Yeah,” the girl said, confused. “Why?”

His mum looked her up and down, then let out a short, ugly laugh. “That’s your half-sister. From my first marriage. I abandoned that lot years ago to start again with your dad.”

The girlfriend froze. Then her face twisted as it clicked.

“You’re… my mum?” She stared at the woman in front of her. “I haven’t seen you since I was a toddler. You left me and my sister at the grocery store one day and never came back.”

Ryan’s cock twitched hard in his boxers. His brain was lighting up like fireworks. He’d just found two more family members to fuck — his own half-sister standing right in front of him, and the possibility of a third (the sister she mentioned). On top of the non-stop breeding sessions he’d been having with his mum all week, trying to put a son in her.

His girlfriend — no, his half-sister — turned on their mum. “Our dad wondered about you for years. Eventually he just gave up.”

Their mum chuckled, completely unbothered. “Well… you found me.”

Ryan couldn’t hold back. He grabbed his half-sister by the waist, spun her toward him, and shoved his tongue deep into her mouth. It was a filthy, aggressive kiss — all tongue and spit, no romance. He licked into her like he was trying to taste every part of her, one hand already sliding down to grope her flat arse and exposed shithole through her clothes.

When he finally pulled back, strings of spit connected their mouths. His eyes were wild.

“I’ve got some news for you,” he said, voice thick with excitement.

Ryan kept his arms around his half-sister, still tasting her spit on his tongue. He looked her dead in the eye.

“You a degenerate?” he asked bluntly.

She shrugged, a bit shy for once. “Well… I do love eating my own boogers.”

He shook his head. “No. Proper bad stuff.”

She hesitated, cheeks flushing. Then she glanced between him and their mum and admitted it.

“I really like eating mine and my sister’s shit. In private, obviously.”

Ryan and his mum immediately clapped hands like they’d just won a bet.

“I fucking knew it,” his mum grinned.

His half-sister blinked. “Why?”

Ryan explained it quick — the generations of incest, how their mum came from her own dad and uncle, how it ran in the blood. Her eyes lit up as the pieces slammed together in her head.

She started talking fast, excited now. “Me and my sister… we’re always eating each other’s arses. Proper deep. We eat each other’s shits too, then make out real deep with it still in our mouths. I was gonna die a virgin, only ever making love with her. You were the first boy I ever had any interest in.”

She looked at him, almost relieved. “It explains so much. Remember that time I drank your piss and we both loved it?”

Ryan nodded, cock twitching. “Yeah. Stuff like that’s just part of the family.”

Their mum stepped in. “We can’t wait to introduce you to your grandmother. She’s even worse than us.”

The half-sister’s face lit up like Christmas. “I’ve got a nan now?” She looked like she might actually cry from excitement.

Their mum pulled her into a hug. They held it for a second, then kissed — soft, almost sweet little pecks.

“Hi,” their mum said quietly.

“Hi,” the daughter answered, just as soft.

Ryan moved in behind his half-sister and wrapped his arms around her waist, pressing his half-hard cock against her flat arse while the two women stayed close.

They eventually pulled apart. His half-sister stood there for a moment, thinking.

“That’s why I don’t mind when Dad molests me,” she said contemplatively. “I always figured it was just part of the family legacy.”

Their mum corrected her straight away. “Nah. That’s something new. He’s not family. He’s just a pervert.”

The girl frowned. “Still feels like incest though.”

“It’s different,” their mum said firmly. “He’s not blood.”

The half-sister nodded slowly, then pulled out her phone and started texting. She looked up at them with a dirty little smile.

“I told her the good news. My sister’s on her way over.”

The knock came while they were still tangled up in the kitchen.

Ryan’s half-sister (the first one) opened the door with a big, filthy grin. The whole family was right behind her — mum in her open dressing gown, bare arse and shithole on show, Ryan in just his boxers and vest, cock already swelling again.

The second sister stepped inside. Same broad shoulders, same coarse oily hair, same flat chest and nonexistent arse, same wild pussy bush. She looked almost identical to her sister, just a bit younger.

She was introduced to her new half-brother first. Ryan gave her a nod and a dirty smile. Then she turned and saw her mum properly for the first time in years.

Her mum just smirked. “Yup. Abandoned you at the grocery store. Left you and your sister there like a pair of unwanted shopping bags.”

Everyone burst out laughing — loud, ugly, genuine laughter that filled the house.

The two sisters didn’t waste another second. They crashed into each other right there in the hallway, kissing hard and messy from the first second. Tongues everywhere, teeth clacking, hands slapping faces and yanking hard on coarse hair. They were moaning already, completely uninhibited, wanting the new family to see exactly who they really were.

Their mum stepped in and put a hand on each of their shoulders, breaking the violent face-sucking.

“Oi. Wait for your nan to get here.”

They pulled apart panting, then hugged and laughed like idiots.

The new sister turned to Ryan. “Hey!”

He grabbed her and they dropped straight into the same kind of violent, nasty kiss. Slapping, hair-pulling, choking each other with hands around throats while their tongues fought deep in each other’s mouths. They licked each other’s faces, licked noses, spat into open mouths and kept going. Moaning, wrestling face-to-face, spit flying.

Their mum and the first sister stood watching, arms around each other, grinning as the new pair fought and spat and choked.

Eventually they slowed down, both of them snorting and gasping for air, faces shiny with spit. They finally broke apart.

“Hey sis.”

“Hey bro.”

Their mum got visibly jealous. “Hell, I want some now.”

The new sister didn’t hesitate. She tangled straight into her mum — arms locked tight around each other’s shoulders — and they smashed their ugly, piggish faces together in a deep, hungry kiss. Mother and long-abandoned daughter, tongues working, spit running down chins.

At the same time, Ryan and his first half-sister turned to each other. They hugged, then fell into their own sloppy, moaning, spit-filled kiss. Tongues face-fucking each other, hands yanking hard on hair, moaning into each other’s mouths like animals.

None of them noticed the front door open again.

Grandma walked in first, looking pleased with herself.

Right behind her came two men.

One was older, broad-shouldered like the women, with the same coarse features — their mother’s father. The other was her brother. The same bloodline that had been fucking and breeding inside this family for generations.

Everyone stopped mid-kiss, mid-grope, and turned.

Then they all cheered — loud, filthy, excited cheering that shook the walls of the little council house.

The cheering died down into excited, filthy laughter as everyone piled into the living room. The little council house suddenly felt too small for the bloodline that had just walked through the door.

Introductions started immediately, everyone talking over each other, hands grabbing, bodies pressing close.

Grandma stood in the middle of it all, grinning with her false teeth in, arms wide. She had never met these two granddaughters before — the daughters her own daughter had abandoned years ago — and they instantly became the center of attention. Both sisters were pulled straight into her. She grabbed their faces with rough hands, turning them side to side like she was inspecting livestock, then yanked them in for big, wet, sloppy kisses on the mouth, one after the other.

“Look at you two,” she rasped, voice thick with pride. “Proper little degenerates already. Same flat arses, same coarse hair, same everything. You’re mine alright.”

The sisters laughed and let her manhandle them, one of them even lifting Grandma’s arm to sniff her armpit on the spot while the other groped her huge belly.

Their mum — the woman who had walked out on them as toddlers — stood frozen for a second when she finally faced her own father.

He was older, broad-shouldered, with the same piggish features and coarse dark hair gone mostly grey. She had never met him. Not once. Her eyes went wide, genuinely blown away.

“Fuck me…” she muttered, stepping forward. “You’re… actually here.”

He just nodded, looking her up and down with the same casual hunger the rest of the family carried. “You turned out just like your mother said you would. Big belly, no arse. Good.”

She didn’t even hesitate. She stepped in and hugged him hard, bellies squashing together, then kissed him on the mouth — not soft, not daughterly. Full on, tongue and all. He kissed her back the same way.

Ryan barely noticed. His eyes were locked on the other new arrival — his grand-uncle. His mum’s brother.

The man looked like an older, thicker, greyer version of Ryan himself. Same broad shoulders, same coarse hair, same heavy features. Same flat arse and heavy gut starting to form. Ryan felt something twist hard in his chest. He was instantly smitten.

“Jesus Christ,” Ryan said under his breath, stepping closer. “You look just like me. Only… older.”

The grand-uncle grinned, showing the same crooked teeth. “That’s the blood talking, lad.” He pulled Ryan straight into a hug, then a rough, deep kiss that Ryan melted into without thinking. Hands grabbed hair. Tongues worked. When they broke apart, Ryan was already breathing heavier, cock visibly tenting his boxers.

The first sister (Ryan’s girlfriend/half-sister) was already on her knees in front of Grandma, face buried between her thighs, licking noisily while the second sister watched and laughed. Their mum was still kissing her own father, one hand down the front of his trousers. The grand-uncle had one thick arm slung around Ryan’s shoulders, casually groping his arse through his boxers like they’d known each other forever.

Every single person in the room had at least one brand-new blood relative to touch, kiss, or claim.

And they were all doing it at once.

The house already reeked of sweat, spit, and the thick, excited stench of a family that had finally come home to itself.


Later that evening, the entire bloodline crammed around the small kitchen table like it was the most natural thing in the world. Plates of greasy takeaway, mashed potatoes, beans, and fried chicken were spread out. Everyone was half-naked or fully naked, bellies out, arses on display, cocks and cunts freely visible. The air already stank of sweat, old farts, and fresh cum from the earlier frenzy.

They ate like absolute animals, finally free to show their worst habits without shame.

Ryan shoved a long, thick chip up one nostril, pushing it deep until snot bubbled around it, then snorted hard and chewed the snot-smeared chip with loud, wet crunches. His new half-sisters did the exact same thing, giggling as they forced sausages up their noses. Their mum rubbed handfuls of mashed potato into her teeth, grinning wide with the white mush packed between them like cheap dentures, then licked it out slowly. Grandma burped loud and long, then casually flicked a booger from her nose straight into her beans before spooning it up. The men weren’t any better — the grandad and grand-uncle chewed with mouths wide open, letting food spill down their chins onto their bellies while loudly sucking their own fingers clean.

They laughed and joked between disgusting mouthfuls.

“Fuck me, the old boys came so fast earlier,” one of the sisters cackled. “Thought Grandad was gonna have a heart attack when he unloaded in me after six pumps.”

The grand-uncle grinned. “Been a while since I had fresh young cunt. Couldn’t help it.”

The girls got the most shit for how much they loved eating arse.

“These two are proper arse addicts,” Ryan’s mum said, pointing at her abandoned daughters. “I’ve never seen anyone tongue a shithole that deep.”

One of the sisters shrugged, mouth full. “We literally eat each other’s shit on a regular basis. This food tastes fucking amazing compared to that.”

Everyone exploded with laughter — loud, ugly, genuine belly laughs that shook the table. Even the old men were in stitches.

It hit them all at once: none of them had ever experienced this level of complete acceptance. No judgment. No hiding. Just pure, filthy family.

Grandma suddenly teared up, her wiry mustache glistening. She raised her glass of cheap lager.

“If I hadn’t encouraged my dad and uncle to stop using condoms all those years ago, none of you beautiful degenerates would be here. Thank you, God, for making us this way.”

Everyone raised their glasses, smiling like idiots, and toasted loudly. “To the bloodline.”

After dinner, the pairing happened naturally.

The two sisters looked at each other, then at the eldest men — their grandfather and grand-uncle — the original seed of the family. They chose them without hesitation.

“Sorry, bro,” one of them said to Ryan with a wink. “We want the source tonight.”

Ryan looked visibly disappointed. He’d been looking forward to another go at his grand-uncle’s loose, experienced arsehole. Instead, he watched the two girls get dragged eagerly into the living room by the older men.

The grandfather and grand-uncle didn’t waste time. They tumbled the sisters onto the dirty rug like animals, cocks already hard again. No foreplay. They simply shoved the girls’ legs apart and rammed their thick, veiny cocks straight into their wombs in one rough thrust each. The girls gasped and clung onto the old men’s backs like octopi, legs wrapped tight, moaning as the raw, generational fucking began. Heavy bellies slapped together. Flat arses jiggled. The men grunted like beasts, pounding away with everything they had left.

The sisters were in absolute heaven — eyes rolling back, piggish faces flushed. They’d gone from feeling like abandoned trash to being willingly bred by the very roots of their degenerate family tree.

Meanwhile, Ryan followed his mum and grandmother into the bedroom.

The two women were already completely naked, big soft bellies pressed together, making out deeply with sloppy, tongue-heavy kisses as they moved. Thick spit ran down their chins. Ryan stripped off his boxers and joined them on the bed, sliding between their warm, unwashed bodies. His mum reached back and guided his cock straight into her loose arsehole while she kept kissing her own mother. Grandma fingered both of them lazily, laughing into the kiss every time someone farted.

The whole house was filled with the sounds of fucking, moaning, slapping flesh, and occasional wet farts for the next couple of hours.

Eventually, everyone retired for the night — exhausted, sticky, satisfied in a way they hadn’t been in years. The council house reeked of sex, shit, and sweat. Bodies were tangled together across beds and couches. The family had never felt more complete.


Epilogue

A few months later, the two sisters were unmistakably showing. Their already soft bellies had swollen into proper pregnant guts — round, heavy, and stretched tight. Their flat chests stayed small, but their nipples had darkened and thickened. The whole family went to the gynecologist together like it was a fucking family outing.

They crammed into the waiting room and then the examination room: Ryan, his mum, Grandma, the grandfather, the grand-uncle, and the two heavily pregnant sisters. The air in the clinic quickly filled with the familiar stench of unwashed bodies, old farts, and general degeneracy.

The doctor delivered the news with a stunned expression.

“Both of you are carrying fraternal twins.”

The first sister — the one who had chosen the eldest men — was pregnant with one baby from her grandfather and one from her grand-uncle. A double blessing from the original seed. The second sister was carrying one from the grand-uncle and one from Ryan — her half-brother.

The entire family erupted in loud, ugly cheers right there in the clinic. Slaps on backs, sloppy kisses, hands rubbing the swollen bellies with open pride.

The lab technician who had run the early genetic tests looked like she was about to be sick. She stared at the results in horror — a tangled, incestuous web of shared DNA that should not have been possible. Multiple overlapping parental lines. She tried to speak but just ended up shaking her head and quietly leaving the room.

The family didn’t care.

Back in the council house that evening, they sat around the kitchen table again, hands resting on the girls’ pregnant bellies.

“Those babies are going to have so much love,” Grandma said, tears in her eyes again. “Real family love. Not that fake normal shit.”

One of the pregnant sisters rubbed her swollen gut and grinned. “I love it. I really like the idea of being the family’s breeding pigs. Just pumping out babies to widen the gene pool. Keep everything nice and close.”

Her sister nodded eagerly. “Same. Fill me up again as soon as these two are out. I want more.”

Ryan leaned over and kissed both of them hard, tongues deep, while their mum and the older men watched with proud, filthy smiles.

They all joined hands around the table — a circle of broad shoulders, coarse hair, big bellies, and flat arses.

Grandma spoke first, voice thick with emotion.

“Thank you, God, for these blessings. For keeping the blood pure and the family growing.”

Everyone repeated it together, voices overlapping in a low, degenerate chorus.

“Thank you, God.”

The house echoed with laughter and the wet sound of celebratory kisses. The girls’ pregnant bellies sat proudly in the middle of it all — living proof that the family’s degenerate legacy was only getting stronger.

And in that filthy council house in the rough corner of Manchester, the bloodline had never been happier.
