1. Why Limestone got the Farm
Every day on the rock farm exhausted Limestone, but today especially. Limestone had spent the last ten hours digging a new mine shaft, and as luck would have it the new location was near a hot spring within the cave system. The whole cave was sweltering hot.
Limestone was so drained that she headed back home before her normal twelve-hour shift had ended. Though that meant she had to walk the whole length of the farm while the Sun was still up, and there had been a heat wave for the past week. Celestia never seemed to account for the communities that had no pegasi to pull in clouds whenever they needed.
By the time she opened the front door and staggered inside, sweat drenched her body. She wobbled to the sink, filling a glass full of water and guzzling it down only to fill it again and gulp down a second.
“Thou art stopping work early?” Igneous said from behind her, as if he'd done a lick of work today.
Great. Limestone hadn't even seen her father in the room. He'd arrived earlier than his daughters as usual; it must be nice to retire and only work six-hour days.
Regardless, Limestone wasn't answering until she finished hydrating herself, so continued gulping down the second glass of water. As she finished it, her father's breath touched her haunches. She tensed as he nosed under her tail and grunted in annoyance as she her dad's breath flowed over her sweaty slit.
“Thou smellest good after a full day working,” he said. “More so today.”
She had just entered her heat and there was no way he couldn’t tell. That wasn't just sweat drooling down her thighs.
“Yeah, whatever. Leave me alone,” Limestone panted as she put down the glass. “I'm going to bed, you fucking pervert.”
“Indeed so,” Igneous said. He was used to Limestone's bitchiness and would not dispute the truth.
He ran his tongue up her slit, tasting her sweaty body and sliding a single hoof beneath to rub at her breasts. He followed up by pushing his head beneath her and slurped the drooling sweat off her breasts. Limestone rolled her eyes, but flagged her tail up weakly and rolled her hips against his affections. She grunted in discontent as he lapped again deeper, pushing her labia apart as he tasted her familiar inner flavor.
“I'm REALLY exhausted right now, Dad,” Limestone grunted, but shivered all the same.
“Then go to thy room and rest,” Igneous said. He grinned against her slit before pulling back.
Panting, Limestone turned. Her father's shaft dangled free of his sheath, already thick and pulsing in a semi-hard state, which didn’t surprise her. Limestone was used to seeing the shaft that made her hard and dangling about. She took a deep breath and headed towards the stairs to go to her room and sighed again as she heard the clop of his hooves as he followed her.
“Celestia damn it,” said Limestone where he could hear her. “So much for going to sleep early. Not with my degenerate dad around I guess.”
Despite her protest, she kept her tailed flagged up in the rear, making sure he could still see her slit. It was drooling more now, thick fluid visibly matting her thigh fur.
“Hmm,” Igneous grunted, his smirk almost audible.
He didn't follow her into her room right away, but Limestone knew he'd be there soon. Once he got his mind on one of his daughter's plots, he could never resist plowing at least one of their holes. Damn guy had an awful lot of energy for that at his age, especially considering their mom hadn't stopped putting out for him. He was probably just stopping at the bathroom to grab a box of condoms.
As exhausted as she was, it would disappoint Limestone if he didn't have a go at her. She'd never admit it outright, but she adored the perverse things he did with them. The wrongness of it had her slick pussy salivating to her ankles as she climbed up onto her bed.
She curled up in a sleeping position so it could annoy her when he roused her, but didn't cover herself. Igneous must love her bitchiness or she wouldn't get so much of his attention. Even when they were all at home, Limestone got more dad dick than her sisters, and that might have been a big reason she inherited ownership of the farm. She lay still, eyes closed and taking deep breaths as if she'd fallen asleep already.
Sure enough she heard his hooves as he trotted into the bedroom, but she continued to feign sleep. He nuzzled at her flank, then pushed her tail out of the way with his nose and give her slit another lap when she didn't respond.
“Celestia fucking damn it,” groaned Limestone as she 'woke up'. “Can I not just sleep without getting molested you lech?!”
Limestone rolled onto her back and kicked a hoof right at his head as hard as she could. He expected it though and caught it with his own, instead pushing it down to spread her hind legs apart. She glared up at him and tried to close them again, but he used his other hoof to hold them apart. He flopped his hard shaft against her moist slit, which Limestone could see throb as it drooled precum onto her belly.
“I said no, Dad!” Limestone growled. “Do you not know what that fucking means?”
“I know what it means when said by thee,” smiled Igneous, on to his tsundere daughter's tricks. He'd seen her send stallions twice his size running, so knew she could stop him if she really wanted.
Limestone swung a forehoof at him, which he caught too, leaning forward to splay her hind legs with his body between them, shaft pulsing rock hard against her belly. He slid it up and down so the underside ground against her slit, its medial ridge flicking against her labia with each pass.
“Fucking gross!” Limestone's face showed disgust, but her pussy slathered his shaft with cunt sap before he even penetrated. “Go fuck my slut sister if you got an incest boner! She's younger than me anyway, damn foalaphile.”
“Thou art both of age,” smiled Igneous. “Besides, she is not my favorite daughter.”
“You say that as if you just started molesting us, you asshole,” growled Limestone. “My first memory is you sneaking in my bedroom and ramming my cunt while I wore my filly guide outfit, and I wasn't even a virgin!”
“Thou makest exaggerations,” Igneous chuckled at her language. “A cute image though.”
Limestone put her front hooves against his chest to push him away. He responded by drawing his own hoof back as if to punch her in the face. She flinched, pulling her front hooves over her face even if she knew he wouldn't hit her. Marble was the only one of them that enjoyed it THAT rough. Still, she didn't want to break the illusion; her dad loved this play as much as she did.
“Don't hurt me!” Limestone said, clenching her teeth as a few tears rolled down her face.
Her look of fear was convincing enough that her father paused and looked concerned, even backing up a few inches. She'd been practicing her abject terror face in a mirror and must have gotten too good at it, because he hadn't hesitated in years.
“Molest away, asshole,” Limestone growled, more tears running down her face. “By Celestia's flaming orgasms, I hate you so much.”
Well, none of that was the safe word, so he smirked and ground his shaft against her again.
“If thou wantest not violence,” said Igneous. “Then thou wilt spread thine legs like a good filly; it is what thou art for.”
“Yeah that's what I'm for,” Limestone grunted. “Aside from running the farm for you, you lazy ass.”
All the same, Limestone splayed her legs wide. They shivered with the effort of feigning reluctance and resisting the urge to just pin her father down and ride him. He purred, getting a better look at her and running his hooves over her body, still moist with perspiration. He felt over her well-toned muscles as they flexed against his hooves.
“My most beloved,” Igneous sighed with lust in his eyes. “Now such a strong and beautiful mare.”
He leaned forward to kiss the tears from one side of her face, then widened his smile as her look of fear faltered into an intense blush. She tried to keep her tears flowing, but it was getting difficult. He slid one hoof down and massaged at her spongy breasts as he moved to lodge his shaft tip against her vulva.
“Dad, stop that shit,” Limestone muttered. “I'm your abused daughter, not your special somepony.”
“Thou art both,” smiled Igneous.
“Uh, Dad,” Limsetone panted as she felt the pressure of his tip increase against her, lower lips spreading. “Aren't you forgetting something?”
“And what is that?” Igneous asked, but he had to know.
“The condom, you moron,” Limestone breathed. Her hooves went to his belly to keep him from pushing into her further. “You had your perv nose against my cunt so you know I'm fertile right now.”
“Yes, I do,” Igneous looked deep into her eyes. “You are a grown mare now. Does thou not want a foal?”
“Don't be stupid,” Limestone rolled her eyes, then paused as she stared up at him and her face slackened. “Fuck, you're serious?”
“Indeed so,” Igneous smiled.
He pushed her forelegs apart and giving another gentle push. Her elastic flesh popped over his tip as he entered her and slid down his bare shaft, letting her feel every curve and vein of the throbbing meat. She tensed, her hind legs kicking on either side of his hips and strained to keep her hips from pressing upward against him.
“Whoa!” Limestone said between clenched teeth. “You can't just knock me up on a whim, asshole! My womb, my rules!”
“I am thine father,” Igneous said as his eyes rolled back. “I need not permission to fill a body I created.”
“The fuck you don't!” shouted Limestone, tears streaming down her face again. “I'm not your fucking sperm sack to make your incest foals!” She breathed heavier and added in a calmer tone. “Dad, seriously, you need to stop and get a condom.”
Limestone moaned as he penetrated her, their moist bellies pushing together, then separating with a lewd slurp as he pulled back. She always loved how his dick stretched her, more when they did it bareback, but now it felt even better. Was it because it was their first time bareback with her in heat? Her pussy was screaming for a load of Daddy's cum, her brain invaded by hormones like she'd never felt before.
“Dost thou remember our safe word?” asked Igneous as he pushed in a second time, her pussy juice oozing down his ball sack.
“Y-yes,” stammered Limestone. It was ‘Rocks suck’, something no Pie would say in a normal circumstance. “B-but...”
Igneous paused his movements, panting from the effort as her pussy squeezed on instinct, rolling up and down his length. He looked into her eyes as if giving her time to decide if she would say it. He had sincere hope in his eyes.
She'd never used the safe word, and took pride in that, but she should definitely do it now. She absolutely knew she should, but when she opened her muzzle, it didn't come out.
“M-Mom will kill us,” Limestone said instead.
“Why so?” asked Igneous, pushing forward again. “She can no longer bear foals and hath always consented to my activities with you.”
“It's my consent you need moron!” Limestone growled. “Seriously, if you want to knock up a daughter, just go put a foal in that slut Marble. That timid cock sock won’t mind.”
“Um...” a quiet voice said from the open bedroom door.
Limestone looked to see her sister Marble, standing just inside the bedroom. If she blushed any brighter, she might be mistaken for that Apple stallion that banged her in front of everyone last Hearth's Warming. Since Marble and Limestone shared the same bed, it wasn't unusual for her to walk in on them, or vice versa.
She still always acted like it was the first time she'd ever seen somepony fucking though. Marble wore an expression like a filly that hadn't noticed that stallions were different until just now. Limestone wondered if she practiced that face in a mirror too.
Igneous either didn't hear or ignored her, instead moving his hips faster, sliding in and out with lewd noises, sending shivers up through Limestone's body. His muscles tensed as he slid one hoof over her body again and massaged her breasts with his other hoof. The breast play had more meaning now that Limestone knew he wanted them to feed their foal.
“Hey Marble,” panted Limestone. “Dad decided it's okay to put a rape foal in me. I don't suppose you'd stop being such a pansy and help me?”
“Mm-hm... c-can I see?” Marble stammered, just audible over the slick sounds of juicy suction as the thrusting increased.
“Of course, my daughter,” panted Igneous.
“I guess that's a no,” Limestone rolled her eyes. “Celestia, you're such a thot."
Marble moved up next to the bed and reluctantly climbed onto it. She found an angle where she could see the penetration between her sister and father and sat there on her haunches. She panted as she slid both front hooves between her own thighs and rubbed at her own slit, but stayed back as if worried she'd disturb their moment.
It surprised Limestone the little masochist didn't try to 'save' Limestone hoping to earn a beating later. Marble must not have been as horny as usual, though that'd change once she watched for a few minutes.
“Y-you really m-making her preggers?” asked Marble.
“Indeed so,” Igneous replied, grasping Limestone's plot in both hooves.
“… hot,” whispered Marble.
"Probably jealous because you're not getting the first rape foal," Limestone snarled at her. "You insufferable little cunt."
"Mm-hm..." Marble admitted in a whisper. Her eyes rolled back slightly at being demeaned. Only she could be so cute and lewd at the same time.
“Stop being adorable,” growled Limestone, as if Marble was capable of such a thing. “It's distracting as Tartarus.”
“Mm-hm,” Marble backed up a step but kept masturbating, licking her lips slightly as she kept staring at the penetration between her father and sister.
As Limestone's vagina tensed and convulsed around his length, Igneous leaned forward to push his muzzle against Limestone's. She growled and pushed his head away.
“I don't want to kiss you, scum bag,” Limestone said. “Does the fact that I don't want this not register with you, moron?”
“Limestone,” smiled Igneous as he stroked her face with one hoof. “Please, allow this moment to be more special than our usual play.”
Limestone grunted again, but didn't push him away as he kissed again. She rolled her eyes but returned it, lapping her tongue against her father's and exploring his gums. She moved her hooves to his face and pulled him closer to deepen the kiss as they stared into one another's eyes.
“You know I love you, Daddy,” Limestone muttered as they pulled apart, saliva still connecting their muzzles for a moment. “I'm mainly just pissed you didn't put one in me years back. It's unlike a pervert like you to wait until I'm legal.”
“You have earned it,” Igneous panted, the bed creaking as his impacts increased. “My only daughter that remained faithful to her father's shaft, even though such a beautiful mare could attract dozens of stallions without effort.”
It wasn't fair to say Limestone was the only faithful one. Pinkie was an apocalypse-level slut and Maud sometimes found a creature that could survive sex with her, but it was Limestone's fault that Marble screwed other stallions. Marble's first dozen dicks other than Daddy's were Limestone including sex with Marble as part of business deals.
“Aww...” Marble squee-ed.
“Shut the fuck up, worthless whore,” Limestone growled at Marble. “We're having a moment.”
Marble moaned more at the derogatory terms. She always loved that, which was a good thing. Limestone doubted even a bitch like herself could bear to insult a cutie like Marble otherwise, and that'd ruin Limestone's reputation of being a total cunt.
Igneous held Limestone's hips more, all four of her legs wrapped around him. His muscles tensed with each delicious thrust into her body. Her tongue slipped out of her muzzle as she drooled, watching the bulge of his shaft move up her belly with each shove. Limestone didn't think she'd ever felt this hot, perhaps because she'd done nothing so perverse as get knocked up by her old man.
Limestone arced her back, huffing as her climax built, but the light in the room turned on and interrupted her. When she looked, her mother Cloudy Quartz was there too with a camera. Limestone blushed as she snapped an image of the father-daughter special moment. Well that answered the question of if Mom was okay with it.
“Damn it Mom, do you have to?” panted Limestone.
“Now, now, dear,” Cloudy said. “This is a special moment. Won't you want a photo to your foal's conception to show to them?”
“You mean a photo for you to clop to, harlot,” growled Limestone, though in honesty she did look forward to embarrassing their offspring with a photo of their conception, much as her parents had with her and her sisters.
Marble moved out of the way of the camera, crawling onto the floor and sliding over to her mother. Limestone panted as she splayed out the hind leg closest to the camera to not block the view, and Igneous raised his front leg on the same side. It left a nice view of her pussy clenching her father's cock, fluid splattering against his thighs with each thrust, drooling down his balls.
Limestone locked eyes with his as the pressure built down below again. She held it as long as she could, knowing her orgasm would set him off, but she wanted this to last as long as possible. And she wanted to cream hard so he'd know how much she wanted this.
She put her front hooves behind her head so the camera could get a full view of her sweat-drenched body, panting and concentrating on holding it off for longer. She kept looking up into her father's passionate eyes, lest the sight of her own bulging stomach make it harder to hold it in.
Igneous never looked at Limestone like this, or any of her sisters that she knew. This was the first time they could call the sex between them love-making. She'd never admitted it even to herself, but she loved her father. Not just in a family way, but a burning romantic passion, wanting nothing more than for him to breed her. She wouldn't be sated until she had more half-sibling children than she had sisters. He'd probably want to fuck them too when they were old enough, but she looked forward to that too.
Her blood was too drenched in hormones for her to ask the obvious questions like “Who will I tell everypony else is the father?”. Instead she flexed her hips, rocking up against him taking him belly deep every thrust. His heavy balls, full of the incestuous fertility she wanted to paint the inside of her womb, smacked against her plot with each stroke.
Her insides tightened with each stroke, twisting and clenching with each stab. Finally she couldn't hold it longer, her orgasm slamming into her like a juicy avalanche. For once she let herself loose, squealing as her body trembled and her tunnel clenched in a flurry of spasms. The pressure sent splurts of her cunt honey all over her father's belly and thighs.
As she rolled her eyes back and her blush lit up like a light house, he was soon to follow. Limestone didn't pretend she didn't want it, shoving her hips upward as he expelled a load of warmth within her. He belly swelled with Daddy's load and he continued to plunge her pussy, packing his fertile seed.
“Mmmph, breed me Daddy!” Limestone cried out more loud than she wanted. “I wanna be your foal factory from now on...”
“That is what thou art now,” Igneous panted as he rubbed his hooves over his pregnant daughter's body once again.
As his hips slowed, keeping his shaft inside her, Limestone realized the room was still full of rather wet noises. She looked over to see her mother, standing on her haunches as she snapped one more photo. Crouched in front of her was Marble, holding her hips and french kissing the hole they had been squeezed out of.
“You gonna fuck your grandkid too, perv?” Limestone looked back up at her panting father.
“Indeed so,” Igneous smiled. “If I am but still alive when she or he is old enough to appreciate such things.”
“Shut up,” Limestone rolled her eyes. “You're not allowed to die until you've fired your cum off in our foal, got it? I'm not kidding. If you do I'll have a seance to bring you back just so they can rape your ethereal ass."
“Indeed so,” Igneous chuckled.
“You gonna knock up Marble now?” Limestone smirked, shifting her hips about to feel the wet stretch of their continued penetration.
“I did not intend to, no,” Igneous said, rubbing his hooves over her body again.
“Yeah, yeah, I'm your favorite,” Limestone rolled her eyes, getting into her more usual mood again. “There's no way a perv like you doesn't want to put one in all his daughters. If you want to show me you love me the most, you'll just have to put more in me than all of them put together.”
Igneous peered at Limestone, then looked back to Marble. Cloudy had put the camera down and had both front hooves on Marble's head, leaning back with her legs spread further as Marble ate her out. Marble had her tail hiked up, her own sopping wet puss drooling down her thighs. As they often did, she'd gone into heat at the same time as her sister; they could both smell it from here.
“Hm,” Igneous considered it.
