Marble Pie joins her father and sister in an incestuous threesome.

It has been a few months now, and Limestone has developed the Rock Farm into a much more thriving business. The only concern she has is, she’s pregnant, with Igneous’ foal; though nopony but her and her father know this. Nopony, except for Marble Pie. After learning about her father and sister’s secret, Marble risks having her own secret being discovered. That not only did she watch the whole incestuous moment happen, but rather enjoyed it.

Marble learns the Truth

The Pie Family Rock Farm has flourished like never before. The income was increasing, with the hire of numerous ponies, and even a couple zebras and yaks, the Farm’s prosperity has grown in the time since Limestone took over. It was almost impossible to think it had been a little over four months. And speaking of four months, it was even more shocking that Limestone was also four months pregnant. Though nopony knew for certain who the father was, Limestone knew who it was. Her father, Igneous Rock; who was enjoying his retirement. Though not as much as he enjoyed watching his sexy daughter flaunt around. With very little clothing capable of fitting her new physique, Limestone was forced to wear her regular close that just barely covered her swelling breasts and couldn’t even cover her baby heavy belly; and even from her pregnancy induced eating, her flank had grown thicker, making her previous comfortable pants into a near skin tight fit. This of course was a sight that not only Igneous enjoyed to watch, but the laborers as well; though there were rumors that one of them was the father, none were brave enough to speak up.

“Did you see Limestone today?” A unicorn stallion asked, using his magic to lift some rubble, keeping his hands steady to focus his magic.

“Yeah, what about her?” An earth stallion commented, breaking through a large rock with his hammer.

“She was so hot today.” The unicorn replied, placing his rubble down. “I mean, did you see what she was wearing.”

“Yak saw that.” A large yak added, his large frame easily breaking through smaller rocks as he trotted and smashed his way around the area. “Yak would smash that. Smash till boss pony couldn’t walk.”

“Yes and her flank, I love how it has grown in mass.” A zebra commented, pushing an empty cart full of supplies such as hammers, shovers, picks, and rope. “I would take my girth and shove it right up her-”

“IF WE ARE DONE HERE!” Shouted a voice that could only belong to Limestone. “I believe we have ROCKS TO BREAK!”

Her attire for the day was as sexy as the mare herself was terrifying. A mid sized dark gray skirt that stretched down to her knees, but seemed to hug her large ass, accompanied by the largest white shirt she could find and even that was only able to cover down to her belly button. It was the large pair of now I cup breasts that Limestone hated that took up almost as much space in her clothing as her belly. But that only kept her in a near constant state of annoyance. Despite being a living wet dream to them, the workers still were greatly intimidated by the mare.

“I’m on it!” The unicorn nodded, doubling his efforts by lifting twice as many rocks with his magic.

“Work, work, work!” The earth stallion commented, swinging his hammer a little faster.

“Yak smash!” The yak shouted, breaking a much larger stone with his head.

“We will finish this, quick as a flash.” The zebra replied, watching as Limestone only grumbled and began to walk away. Though he would never say it, his mind made it quite clear. ‘One day, I’ll fuck you so hard, you’ll get whiplash.’

“Stupid perverted, ugh!” Limestone growled in frustration, slamming the door to her room in a rage; nearly shaking the house. Laying on her bed, the mare wasted no time ripping off her tight pants and loose shirt. “Stupid, uncomfortable clothes, stupid pregnancy, stupid mood swings, stupid ugh!”

Now that she was fully naked, Limestone felt some relief from her frustrations. Though not enough to quell her rage. Her hated breasts were bigger than before. Too big for any bra she could have, and the one she had Pinkie order from Rarity was the only pair she had and it irritated her sensitive nipple; which had started leaking some milk. Fortunately, Limestone was able to find some pasties to cover her nipples; but trying to take them off was still a pain. The feeling of her nipples being teased in any way sent shivers of pleasure through her body. But just as she finally managed to get the pasties off, a knock came to the door.

“Who’s there?” Limestone called, her angry tone nearly burning a hole through the door.

“It’s me.” Marble replied, her weak and timid voice was unmistakable. “C-can I come in?”

“Sure.” Limestone replied, not bothering to cover herself, she trusted Marble enough.

Walking in the room, and quickly closing the door so no one could see Limestone naked, Marble stood rather nervously. She had always been a shy one, one that Limestone knew some sleazy stallion would try to take advantage of, that’s why she always tried to protect her. And Marble, though intimidated by Limestone, respected her for her bravery and confidence. Though currently, Limestone envied what Marble was wearing. A nice thin, long sleeved powder grey turtleneck, and a pair of loose fitting, long black pants. Limestone wished she could wear something, anything to hide her pregnant body from the world.

“What is it Marble?” Limestone asked, trying to guess what Marble had to say.

“I’m just letting you know that Maud, mother, and I are going to do the monthly supply trip to the town a few miles over.” Marble replied, much to Limestones disdain for them leaving her alone with her father and the perverted workers. “I know you hate it, but we’ll be back really quick this time.”

“Be sure that you do.” Limestone replied, trying to hold back her anger as to not direct it to her innocent sister. “I hate being alone with those stupid morons I hired.”

“O-okay Limestone.” Marble nodded before turning to leave. “Just try to take the rest of the day to relax. I know...I know being pregnant can be stressful.”

“Thanks Marble.” Limestone replied with an attempted smile, but just as her sister left, the mare grumbled. “But that’s the least of my problems.” Turning her head, though Limestone couldn’t see it, she knew Igneous was watching her through the small hole in the wall. Even after numerous attempts to cover it, the hole always returned. After a while, Limestone stopped caring and only grew a greater hatred for her father. “What do you want?” There was no response, but a moment later, a small knock echoed from the wall. Almost like a morse code, the knock had a small, rhythmic pattern, and Limestone knew what it meant. “Come to your room? What, so you can try and knock me up even more. No thanks.” Another, slightly different knock followed. “You want to just talk? Ugh fine, I don’t trust you for a second, but fine, whatever. Not like you can do anything worse to me.” Reluctantly, Limestone through on her long shirt and low skirt without even putting back on her bra or pasties as she made her way to the door to “speak” with her father.

Knocking on the door, in a way only her and her father would know, Limestone didn’t wait long as Igneous made a sort of grunting sound, signalling her to enter. Once the door was open, Limestone almost immediately regretted it. Laying across the bed, naked, and with his large hard cock standing stiff was Igneous, his eyes looking Limestone over as she cringed in frustration. But she also knew what this meant and quickly and quietly closed the door; making sure to lock it. Even though she now legally owned the farm, and there was no way for her father to take that from her, and by no means did she need to even be in the same room as her naked father, Limestone had grown attached to Igneous’ cock. Not an addiction but more like a pregnancy craving.

During her pregnancy, Limestone had become incredibly horny and there were no suitable males for miles. She didn’t want to fuck the workers, that would make her appear to be a loose slut and not the stern boss she wanted them to see her as. And her father, despite knocking her up, was very good at sex. Igneous only nodded, silently ordering his daughter to get naked as well. With how his cock twitched, Limestone knew he wouldn’t be satisfied unless it came multiple times all over her. She knew this wasn’t a coincidence, with the rest of her family leaving to get supplies and the workers too scared to enter the house, it was the perfect time to fuck. And Limestone hated it. She hated how big that cock was, how she could feel her pussy ache to be filled, and how strong the musky smell was.

“Let’s just get this over with.” Limestone grunted, now fully naked and walking over to her father. By how he laid down, he wanted her to ride him. But Limestone only grabbed the thick cock and started jerking it as she licked her lips in anticipation. “Don’t say a fucking word.”

Opening her mouth, Limestone licked at the tip, wasting no time to shoved the first half of the shaft in her mouth. Igneous only smiled as he watched his pregnant daughter service him like that. Regardless of how dominating she wanted to be, he knew after months of fucking her that Limestone was his little pregnant fuck slut. She just couldn’t kick her stubborn side. Which was fine, he loved making his strong willed daughter squeal and moan under his cock. It was a pleasure that made his cock even hard, the thought of how he’d make Limestone beg for more was already making his cock thicker and longer in the mare’s mouth.

Limestone felt her father grow bigger in her mouth, she knew he was loving it, and she hated him, hated how delicious his cock was, and hated how she could feel her pussy dripping wetter as she took more of the cock into her mouth. Before long, Igneous’ cock had already reached the back of her throat, but he still wanted her to press herself further; deep throating his dick until she gagged. But Limestone was in no mood to be facefuked by her father. Forcing herself off him, the mare caught her breath before lowering again, but this time suckling at his heavy, cum filled balls. She knew how much he liked this, and she wanted to just get this over with.

“Oh come now.” Igneous spoke up, much to the angry glares of his daughter. “No need to get so moody, you love this as much as I do.”

“Even if I somehow, for some asinine reason, would ever enjoy this.” Limestone snapped, her tone almost stabbing at the stallion. “I still hate you for lying to me, for knocking me up, and then making me do this every time you get hard to stupid horny old stallion.”

“You never say no.” Igneous replied, chuckling as he gently rubbed Limestone’s head. “Besides, I thought what you told your mother was clever. Making her think one of the help impregnated you.”

“Didn’t give me much choice.” Limestone groaned, still suckling at Igenous’ balls, stroking his cock with her hand. “Just shut up and cum already, I want to shower sometime you know.”

As Igneous continued to pet his daughter, and Limestone suckled at her father, both failed to notice they were not completely alone. Peeking through the door keyhole, Marble Pie, who had forgotten something and chose to return to the farm, watched her sister being used by their father. What she saw was so different from how Limestone usually was, how she was so strong willed only to be their father’s plaything. But despite watching and knowing how wrong this was, Marble felt her body tingling as she looked on. Her pussy quivered, aching to be touched as she watched her sister sucking off her father. Before she realized it, one of Marble’s hands had sunk in her loose fitting pants, gently rubbing at her eager and sensitive pussy.

Marble was always the shy mare others saw her to be. But she was still a mare, and a mare always had needs. Not as sexually open as Pinkie, or sexually apathetic as Maud, Marble was a closeted pervert, fantasizing about what stallions and mares do together, but never having the courage to act on them. But today was different. Today, Marble was nervous and scared of getting caught, but instead of the fear causing her to run, but kept her in place; and it only made her pussy wetter and itching to be teased and played with.

Watching on, Marble saw as Limestone removed herself from Igneous’ cock, getting read to ride the thick shaft. Marble started rubbing her pussy lips even faster, even taking her free hand to grope at her breasts, pinching her nipple and trying to hold back her moans. But just as she saw the thick and twitching cock about to plunge itself in Limestone’s dripping wet pussy, Marble let out a small squeaking sound as she moaned. This was a big mistake. It was loud enough where both Limestone and Igneous heard the noise.

“Who’s there?!” Limestone called in anger, nearly charging at the door. “I swear, if it’s that stupid unicorn, I’m gonna-” But as she nearly tore the door open, her blood ran cold as she saw the peeping pony was Marble. “M-Marble?!”

“I-I’m sorry.” Marble said, getting ready to get up and run, but Limestone grabbed her, pulling her in the room and slamming to door shut. “What did you see?”

“I-I-I-I saw you...and father...you were...eep…” Marble stuttered, terrified as to what she had done. “I-I-I’m sorry. I won’t tell anypony, I swear…”

“Ugh...damn it!” Limestone groaned in frustration. What was she to do. But this was Marble. Marble wasn’t going to tell anyone, but she was still going to be curious. “Fine, I trust you. But since you found out, you should know the truth.” Taking a deep breath, Limestone did her best to explain her words carefully. “Four months ago, when I wanted the farm to be given to me, you know father refused.” Marble nodded her head. “But I also found out father is a disgusting pervert who’s been watching us naked in our rooms for who knows how long.” Marble’s eyes widened in shock, wondering how many times her father had watched her play with herself in her room. “So the deal was, I sleep with father, and he gives me the farm.”

“But then, why are you still-” Marble asked, but was stopped by Limestone’s finger on her lips.

“Because I’ve been knocked up, I’m almost always horny and father is unfortunately the only suitable dick around.” Limestone sighed, feeling a shiver run down her spine as she explained.

“But now, what to do with you?” Igneous asked, getting up from the bed, walking his naked body over, showing off his still hard and wet cock to his youngest daughter.

“No, not her!” Limestone snapped, stepping between the two. “I’m good enough, and we are finishing this in a minute!”

“But she found out.” Igneous explained, his tone sounding like a scolding parent. “She spied on us in our private moment and was even touching herself as she watching.” Marble stiffened as her wet hand had been noticed. “Such a naughty mare needs to be punished.” Igneous licked his lips and stroked himself as he said his last words.

“Not...her…” Limestone repeated, only to have Marble place her hand on her arm. “Marble?”

“It’s okay Limestone.” Marble said, though her nervous words revealed how scared she was. “Father’s right. And I can’t have you do this alone. Let me help my sister.”

“Then it’s decided.” Igneous nodded, turning to return to the bed, laying back and beckoning the mares to come to him. “Let us have a better father, daughter, and daughter time together.” Limestone hated it, but reluctantly did nothing as Marble fully stripped out of her clothing in front of their eager father, who still beckoned them to approach.

Reluctantly, Limestone and Marble walked over to their aroused father, both of their eyes staring more at his rigid erection and not at the smug smirk he held across his face. Taking his cock in hand, Igneous started to slowly stroke it off, making sure his daughters got a good, long look at how he wanted them to embrace their urges and savor his dick. While Limestone held a blush, but showed some signs of resistance, Marble was almost spellbound, staring at the cock as her lips quivered. Reaching out, both mares grabbed the shaft, slowly and gently starting to stroke it as the two tried to form some sort of jerking pattern.

“Mmm that’s right.” Igneous groaned, feeling both the gentle hand of Marble, and firm grip of Limestone work his cock over. “Don’t stay too long girls, I want both your mouths on it.”

Almost snarling, but wanting to spare Marble the shame, Limestone opened her mouth and started taking in some of Igneous’ cock, easily stuffing half the thick girth in her wet maw as she and her sister continued stroking it. Igneous wasted no time, taking his hand and pressing Limestone’s face against his cock, taking in the full length of the thick cock in her mouth, striking the back of her throat as she was forced to deep throat it all. Marble could only watch with awe and intimidation as she saw her big sister being essentially face raped by their father’s huge cock. Her body shivered with fear, but the fear also made her body feel hot, very hot. Marble felt her pussy itch and ache, begging to be touched, but the strong musk of her father, mixed with the erotic display of her sister were too much for the mare to handle.

Leaning down, Marble ran her tongue along Igneous’ cock, going down until she reached his huge, cum filled balls. Wasting no time, Marble took one ball in her mouth and started to suckle at it, using one hand to fondle the other ball, and her other hand to feverishly rub and finger her dripping pussy. Marble moaned against her father’s sack as she engaged in this ball worship, the strong musk burned her nostrils, and dulled her senses. It was becoming more and more difficult to remember it was her father’s balls the mare was suckling. Igneous didn’t mind, her only leaned back and savored the feeling of both his beautiful daughters sucking and suckling him off. He could even feel himself ready to cum.

“It’s coming Limestone.” Igneous smirked, keeping a hand on Limestone’s as he thrusted against her mouth pussy, while having his other hand pet Marble like a darling pet. “When I finish busting in your sister, it’ll be your turn Marble.”

Marble felt her pussy get wetter at the thought of her father giving her such attention. This new world of lust, passion, and sex was overwhelming the mare’s sense of reason and restraint. She could never deny her father’s advances after this, with how good this was feeling, she welcomed it. Igneous released his hold of Marble and grabbed Limestone with both hands, ramming his cock in and out of ther throat in a faster, more aggressive thrusting motion. Limestone gagged and coughed as the cock beat against the room of her mouth as she could feel it swelling inside her. He was about to cum and she couldn’t stop the torrent from coming.

“Drink it down!” Igneous grunted, feeling his balls tighten and release his thick load, firing it to the back of Limestone’s mouth.

Limestone’s eyes burst wide open as the heavy load of cum shot to the back of her throat, puffing her cheeks and forcing her to swallow each thick, heavy, and hot load that Igneous pumped and twitched inside her. Marble felt her father’s balls tighten in her mouth, her playful tongue could almost feel the flow of cum drain from the sack and move through the much thicked, swollen cock. She watched in awe as she saw not only Limestone take such a heavy load of cum, but she could smell Limestone climaxing from the feeling of being face raped and came into.

“Ahh, so good.” Igneous groaned, releasing Limestone, letting the mare off his cock so she could gag, cough, and breathe again. Limestone did just that, but some cum gushed from her mouth as she struggled for air. Powerless, she was unable to stop Igneous as he lifted himself up and grabbed at Marble’s shoulders; the timid mare shivered at her father’s touch. “Your turn my dear.”

Not giving her the chance to reply or respond, Igneous pulled Marble, turning her around and gently slamming her against the edge of the bed. With little a word, Igneous slapped his wet and still hard cock against his daughter’s face, savoring as the mare’s expression was a mix of fear and arousal. The strong musk striking her mind, followed by the wet kiss of the slick shaft against her. It was too much. Marble’s quivering mouth opened a little, just enough for Igneous to align and ram his cock in her maw. Marble’s eyes shot open, shocked that her father gave her no warm up, or a chance to get accustomed to his size. No, Igneous shoved his full length and began to hump Marble’s face with a greater ferocity he had when face fucking Limestone.

“Fuck, this is more like it.” Igneous moaned, looking down as the weak expression in Marble’s eyes. “A timid mare like you, sucking my massive cock. I should’ve done this years again. Two of my daughters, the perfect cock sleeves.”

Igneous continued to shove his cock in and out of Marble’s mouth, humping against her face as if it were a loose pussy. Marble’s eyes rolled back as she felt her body succumb to her father’s advances. She was his toy, a flesh hole for him to use and cum in. Marble’s mind was too weak to hold back her pleasure. She wasn’t even aware that she was feverishly masturbating as her father was brutally facefucking her. Igneous continued, thrusting himself in and out of Marble’s mouth as he moved.

“Fuck Marble.” Igneous grunted. “Your mouth is better than your sister, I’m gonna bust my load in that soft mouth of yours.” Marble’s mouth tightened for a moment, feeling the swelling cock ready to burst inside her. “Here it comes!”

Letting out his next burst of cum, Igneous shoved his length as deep as he could in Marble’s mouth, causing the timid, blushing mare to gag on the size of the shaft and volume of the cum. But just as fast as he rammed it in, the stallion pulled himself out, savoring the sight of his daughter coughing up his thick load. Igneous smirked at the sight, it was practically a sign of dominance to make a mare choke on his cum. BUt it was even more dominating to make the mare keep it in her mouth.

“Marble.” Igneous ordered in a stern tone, looking down on the mare. “A real mare doesn’t cough up a stallion’s cum.” Marble quickly covered her mouth with her hand, but she wasn’t fast enough to stop most of the cum from gushing out. “I see, okay, it looks like you need to be properly trained. Limestone?” Looking over, he saw that Limestone was a little more active, or at least had enough strength to move. “Show her how to hold in your father’s cum.”

Limestone somewhat silently obeyed her father, hating it, but her pusy quivered at how stern his voice was as he ordered her. She hated being dominated like that, but it turned her on so much to be treated like that. Begrudgingly, Limestone crawled to Marble, grabbed her sister’s arm and only gave her an apologetic look before smaking both their lips together. Marble was taken so off guard by this, that she didn’t even resist as Limestone shoved her tongue in her sister’s mouth, the two mares swapping and changing the cum they received from their father’s massive and violent cock. Marble only wrapped her arms around her sister as she moaned into the kiss, giving into the pleasure it brought.

“Very good.” Igneous smiled, gently patting both his daughters’ heads. His tone and voice almost sounding like a caring father, but his thick and throbbing cock showed him off to be the pervert who was more than ready to fuck both his daughters into a twitching mess. “Now then Limestone.” Grabbing at Limestone’s arm, Igneous pulled, separating the two from their moaning kiss. “I think we should show Marble how we enjoy ourselves.”

Lifting his daughter upwards, Igneous held Limestone, bending his knees to support the mare’s spread legs. His arms wrapped up her back, around the arms and rested on the back of her head. This concluded with Igneous making sure Limestone’s pregnant belly was facing outward, staring Marble in the blushing face. Marble only watched with a silent shyness and wonder as she watched her sister being held like a sexy toy, her father’s cock aiming upwards and was set to ram itself in Limestone’s pussy.

“Enjoy the view Marble.” Igneous smirked, getting ready, kissing his cockhead at Limestone’s dripping wet entrance. “Ready Limestone?”

“Just get it over with you fuc-ahh!” Limestone tried to say but was interrupted by Igneous’ cock being shoved deep in her pregnant pussy, pressing against her swollen and sensitive womb with the first thrust. “C-careful, y-you’ll hurt the baby.”

“It’s a Pie baby, it can take it.” Igneous replied, continuing his unrelenting amount of thrusts, making Limestone’s body shake and her heavy breasts bounce from the motion. But this wasn’t enough, a thought struck the stallion’s mind. Something he needed another mare for. “Marble, don’t just sit there. I want you to show your sister how good you want to feel. How much you want your father’s cock when he’s down fucking her.”

Marble did as she was told, though she wasn't sure what to do. She let go of thought, realizing it only made the situation more confusing. Giving more into her instinct and desires, Marble closed her eyes and leaned forward. Letting her passion and pleasure guide her actions, her opened her mouth and let her cum and saliva covered tongue hang out, until it reached the base of Igneous’ cock. Wasting no time, running her wet and shivering tongue from the base of Igneous’ cock and balls, and ran it upwards until it met with Limestone’s pussy lips and quivering clit. Both Igneous and Limestone shook a little from the sudden feeling, but the stallion only picked up his thrusting speed while the mare simply moaned loudly.

“Fuck.” Limestone grunted and moaned, not wanting to give her father the satisfaction that he was making her cum all over his cock and Marble’s tongue, but the feeling of Igneous’ cock inside her, pressing against her inner folds, kissing at her womb, and tingling her sweet spots, she couldn’t help but cum from the cock being viciously buried in and out of her pussy. “J-just fucking cum!”

“And give you another dose of my spunk?” Igneous replied, raising his eyebrow. “I know how much you want it, but I was thinking we have Marble take my full load.” Limestone tried to say something. She knew all too well what her father was planning. He was thinking to knock Marble up just as he did with her. But she was powerless to stop him, even her pussy was betraying her by how wet and tight it was becoming on Igneous’ dick. But as he continued his thrusting, Igneous’ rhythm changed. “Don’t worry. You’ll get your share of my cum first my dear. We need to feed my foal.”

Shoving his full length nearly past Limestone’s womb, Igneous’ cock released another thick load of cum, stuffing his daughter’s pussy with the thick spunk. His cock swelled in her pussy, blocking most of the cum from escaping, save for a few trickles. Which Marble, who was still licking, lapped it up like a small animal licking at milk. Limestone gasped as she felt her insides being filled with the thick load. If she wasn’t already pregnant, she knew this would have knocked her up again. Or at the very least, cause her belly to swell as it did the first time they fucked.

“Very good. That felt just perfect Limestone.” Igneous commented, leaning in towards Limestone's mouth. Letting out his tongue, he kissed at his daughter’s open mouth, the two shared their open mouth tongue kiss as Marble cleaned both their genitals with her eager, and growing in skill tongue. Pulling back, Igneous directed his gaze down to Marble. “Marble, lay on the bed, it’s almost your turn.”

Nodding, yet only making a whimpering noise, Marble struggled to lift herself up as she spread herself on the back, having her legs dangle off the end of the bed but letting her arms rest more by her sides. Limestone looked at her sister, the embarrassment of cumming in front of her was bad enough, having this big cock that made her cum so hard was even worse. She wanted this all to end, but her more turned on thoughts wanted her father to wreck her pussy and make Marble watch. Showing a great deal of caution, Igneous carefully lowered Limestone down, pressing her sweaty and heavy bellied body against Marble’s soft and warm body.

“S-sister.” Marble moaned, her arms moving on their own as they began to wrap around Limestone, touching, rubbing, and exploring her body with every touch. “It looked like it felt so good.”

“Marble.” Limestone replied, feeling her body almost melt at Marble’s touch before her own hands began to explore her sister’s body.

“Make me feel good.” Marble moaned, begging for Limestone to touch her more as she kissed passionately against her sister’s lips. Her hands rubbed along her shoulder as she held her close with each passing moment.

“Looks like she’s getting more honest with herself.” Igneous said, smiling as he jerked his half erect cock back to full stiffness. Leaning in, he guided his cock towards the mares’ dripping entrances, but instead of shoving himself full force into one of them, Igneous chose to slowly wedge his cock between the two. “Mmm yes, that’s much better.”

Leaning down, Igneous grabbed at Limestone’s hips, thrusting in and out between the two mares. His thick, cum and juice coated cock rubbing hard against their quivering clits. Both mares moaned into each others’ mouths as they felt their pussies quiver and leak from the feeling. They shivered as they embraced each other in a passionate manner, their bodies melded together and they rubbed and started to grind against each other. Igneous felt his cock grow hotter from the feeling, he could almost feel his balls churning with the next fertile load of cum.

“Time to help the family grow.” Igneous smirked, licking his lips as as saw his words fell on deaf ears as both Marble and Limestone were too engrossed in each other to notice him as he slide his cock out from between them, realigning it, and aiming it to shove itself in Marble’s virginal and winking pussy. “I haven’t even shoved it in and it already feels good.”

Pressing forward, Igneous felt almost no resistance as his cock wedged its way in Marble’s pussy. But as he plunged himself slowly in his daughter’s wet hole, he noticed to some surprise that there was no hymen. There was certainly no way for Marble to have hooked up with any stallion, but it wa possible the closeted pervert had lost her virginity to a large dildo. Not that it mattered, this only allowed him to shove his way in her shivering body much easier.

“Aww yeah, just like that Marble.” Igneous groaned, feeling Marble’s pussy coil around his cock in an almost loving embrace. She was softer and more giving than Limestone. There was no resistance, if anything, her pussy was swallowing his thick shaft as it easily slid inside the slick and wet entrance. “Oh, yes, that feels good.”

Starting slow, but picking up in speed, Igneous started fucking in and out of his daughter’s pussy with less and less restraint. Marble only seemed to moan more in Limestone’s mouth as she felt her pussy send her body and mind into a near endless series of orgasms. Limestone moaned back into her sister’s mouth, her cum filled belly gushing out the thick spunk as she pressed and rubbed her body against Marble’s body. Marble moaned and rubbed herself harder, sweat soaking her pleasured body as she felt herself being driven closer and closer to orgasm.

“Just a little more Marble.” Igneous groaned, feeling his balls tighten and cock swell in the soft love canal. “I’m gonna cum straight in your open womb.”

Pulling nearly his full length out, Igneous then shoved himself to the hilt, bottoming out his cock deep in Marble’s body, pushing passed her quivering certix as she reached a hard and violent orgasm, welcoming the thick and hot cum that filled her womb within the first burst. Igneous gritted his teeth as he unloaded serval thick and long ropes in Marble’s pussy. Marble, herself, moaned and kissed harder and more passionately into Limestone’s mouth. Igneous kept his cock in place, only sliding a little in and out to keep is vast load in place, causing his daughter’s belly to bulge from the load. There was no doubt about it, he had just knocked off his other daughter. Igneous continued to stay inside Marble, savoring the afterglow of his orgasm. Now with both Limestone and Marble, he would have a lot of fun when the others would go on their shopping trip.

It was about four months after that day, and Igneous, Limestone, and Marble’s relationship had drastically changed. Limestone was still the hard ass owner of the farm, but after being pregnant for eight months, she was almost constantly horny. But after every hard day working the farm she would always find her way back to her father and always was able to find some time for a quickie. While Marble, now a solid four months pregnant, was fucking her father every free moment she got. More than once, she was nearly caught by Maud, but thankfully, Limestone was able to distract her. Though she always had a look as if she knew.

But it was time again for the monthly shopping. With Marble being pregnant, and Limestone being so far along pregnant, the responsibility of shopping fell on Maud and Cloudy Quartz. Though they didn’t mind going as just the two of them, Igneous and his other daughters loved it. It was the only chance the three could have their near nonstop threesome of wet and sloppy pleasure. Marble was fully addicted to her father’s cock, while Limestone resisted but couldn’t stop herself from bouncing on the thick shaft as it made her pussy gush juices and squirt all over Marble’s face as she often would eat her sister out of worship her father’s balls during sex.

Sitting on the train to the nearby town, Maud and Cloudy stared off into the vast farm lands. Though Maud was not much of a talker, she was very observant. It wasn’t obvious, or even considered. But she had long figured out what was happening. She knew about Limestone when she first seduced Igneous to get the farm, and it was pretty obvious that her father also got Marble pregnant. But Maud said nothing. Nothing to them anyways. Looking over to her mother, Maud only seemed to look past her but still in her direction.
