Like the tolling of a lonesome gong, Limestone Pie's spade clangs endlessly against the rocky soil of the Pie Family fields. April is unseasonably warm, and the scorching sun threatens to undo her bid to get the latest boulder crop in the ground during high planting season.

Fearing her sister will succumb to heat stroke, Marble Pie seeks to distract Limestone's attention. Better than a glass of iced tea in a stuffy house is time spent with the cool crystalline formations of the family mines - in demand more than ever since the reappearance of the Crystal Empire. There's more to Marble's relaxation regimen than simple rock-hugging though, and the Pie sisters are about to share in a family tradition that brought them all close together when a certain pink sister went off on her own to live in Ponyville.

Sowing the Seed

Like the tolling of a lonesome gong, a sharp clang of metal on granite rang out across empty, open plains. The sound stretched from horizon to horizon, dissipating harmlessly in every direction save for the path it took between Limestone Pie’s ears.

Comparable to the four or five hundred of its siblings that had lived and died over the span of the last hour, this soundwave also ripped at Limestone’s eardrums like the unpleasant edge of hooves on a chalkboard. The eldest sibling of the Pie family gritted her teeth against it, darkening the furrow of her weather-beaten brow; but the sound left her no quarter as it sent a shiver down her spine, beneath her red-checkered blouse.

“Dammit!” She growled, yanking the heavy spade she used to tear at the earth away from her chosen digging spot. “How is anybody supposed to plant a new rock crop with all these rocks in the soil!? There’s no way there were this many last season!”

Limestone ran the figures from the last harvest in her head, attempting to recall just how many ripe boulders had been dug from the ground with chips taken out of them. Any number of factors could weaken the structure of a fine construction rock and cause pieces of it to break away; from erosion, to earthquakes, to persistent plant growth. When the rocks were shipped off to some city to serve in the foundations of enterprising contractors, it was an inevitability that a few shards would be left behind.

Limestone scowled at the fields and made a mental note to curse a lot later on at dinner. So many shards left behind was a clear indication the last harvest had been sloppy.

“Ugh,” Limestone rose to her full height and cast the spade aside - the implement added insult to injury by clanging once again against a discarded rock shard as it impacted with the soil. “Somebody tell Canterlot to turn the sun down today, this is ridiculous...”

Regardless of her opinion of the rock crop, Limestone felt assured that there could be no debate concerning her estimation of the weather. The punishing heat of Celestia’s grace in the sky was unseasonable for April, but the considerably dry conditions that had persisted all month long were downright bizarre. The combination of the two, combined with the lack of distracting vegetation on a rock farm, made the Pie Family abode feel more like a desert in the height of August’s fire.

Wiping her brow on her rolled-up sleeve, Limestone turned her lidded eyes away from the sun and took to rummaging around in a nearby cart filled with ‘fertile’ rocks for a bottle of water. The aluminum cylinder she eventually wrapped her fingers around was a poor choice of material for the afternoon, given that it had become so hot, she could barely handle it. Deciding that ‘barely’ would do, she un-stoppered the bottle and greedily gulped down a few swallows of warm water, before dumping the remainder of the contents unceremoniously all over her head.

She let out a deep, guttural sigh as the persistent moisture mingled with the sweat on her scalp, soothing her senses even as it matted her short, straight head of gray hair to the form of her head and neck. She then shook her head from side to side like a dog drying itself, sending little droplets of clear liquid to sizzle against the chunks of stone that lay all around.

Enjoying a moment of respite, Limestone thought upon the precise method by which one plants a rock for eventual harvesting. It was as much trademark knowledge of the Pie family as appraising the difference between a chunk that was equal to the task versus one that was not. She enjoyed the singing ring emitted by a fertile hunk of basalt or slate, but the jarring crack of a bit of rock that was deemed of no value stung her like a mental papercut.

The difference between the two melodies is best left to the depths of a professional rock farmer’s temperament.

Though loathe to admit to weakness, Limestone recognized that to continue without any sort of break would invite a condition whereupon she could not work at all. With her father busy in the mines, her mother gone to the market for the day with Maud, and her younger sister as useless for such tasks as always, there was nobody else to get the job done. It was a fact she had a tendency to remind her family of frequently.

Limestone glanced about, quickly locating the discarded spade. She felt her eyes wandering beyond it, and as her memories sketched phantasmal images of her family members upon the horizon, she noticed that one such phantom did not vanish a few seconds after it appeared. She squinted, focusing her attention across the fields as she spied the form of her youngest sister, Marble. The little slip of a young lady was squatting on her hooves in the distance, fidgeting with something near the ground. The spaghetti-strap sundress that was so close to the tone of her own skin trickled down her shoulders like water, smoothing out perfectly at her shins as it flowed over the contours of her haunches. Upon Marble’s head was a wide-brimmed, white bonnet that just barely kept her long locks out of her violet eyes.

Limestone thought her sister’s accessory wise, if for no other reason than to make up for Marble’s otherwise foolish decision to walk around in such harsh sunlight bare of shoulder. Limestone was quite certain that the rays from the sky were scorching enough to tan even the steel-gray pallor that most of the Pie sisters shared.

The eldest Pie sister summoned a hand that had taken root in the pocket of her work jeans and shielded her eyes with it, muttering to herself, “What are you up to...”

When the world came into better focus, it became apparent that Marble was poking at the base of a huge, ovoid boulder that sat in state on a granite dais near the Pie family homestead.

Limestone’s apple-green eyes went wide. The familiar fires of her rage flamed, and her legs broke into a run without conscious thought.

“Hey!” She bellowed, closing quickly with her target and heedless of the heat, “What do you think you’re doing!? What have I told you about touching Holder's Boulder!?”

Marble, in an unusual display of boldness, touched her dainty finger to the massive surface of the historical rock, lowered herself the rest of the way to her knees, smoothed her skirt out properly, and waited for her elder sister to enter her personal space bubble. Limestone did not disappoint. In an instant, she was towering over her little sister, her chest heaving with effort under the undone two buttons at the top of her shirt.

Limestone thrust her hand out at the contact between Marble and the boulder. “What is this supposed to be?” She growled, “Do you want Holder's Boulder to end up in the quarry again? Because you’re shoving him back up here yourself if that happens!”

Marble, smiling as though with accomplishment, removed her finger from the stone and rose to her hooves, again smoothing out her dress as she went. A breeze fluttered the fabric around her - on such a still day, it was as though the very wind had chosen to add a bit of dramatic effect for Marble’s benefit.

“I can’t get your attention otherwise,” Marble said simply. “Once you start working, nobody can get your attention for anything except more work.”

Marble narrowed her eyes and folded her arms over her chest. “Fine. You got my attention. What do you want? Just because mom’s gone to market doesn’t mean you can goof off about the inside chores, you know. Rock soup doesn’t make itself.”

Marble’s smile wilted at the edges slightly, concern pooling into it. “You’re working too hard.”

“Tch, what?” Limestone rolled her eyes and turned partially away. “I don’t have time to talk about that. Who’s going to get the rocks in the ground in time for the season if I don’t do it, huh?”

“...it doesn’t really matter when rocks get into the ground...” Marble muttered.

“What?”

“N-nothing!” Marble waved her hand dismissively and took a step back. The movement shook some of her tresses free from her bonnet, and her left eye vanished beneath them. “I’m just worried about you,” She commented. “Even dad wouldn’t want you to work so hard on this kind of day. You’re going to get heat stroke.”

“I am not,” Limestone insisted. “I can handle anything. I run this whole place after all.”

Marble, unconvinced, stuck a single finger up in the air, “How many fingers am I holding up?”

“Um, duh? One?”

Marble then began waving the outstretched finger back and forth quickly in the air, “How about now?”

Limestone spent approximately two and a half seconds trying to follow the waggling finger before she felt nauseous. Contrary to her own rules, she propped herself up with one hand on Holder's Boulder and shut her eyes, bowing her head and rubbing at her temple with a wincing grunt.

“Sorry,” Marble apologized. “But I knew you wouldn’t believe me if I didn’t prove it. You’re dizzy and you’re tired. You need to go someplace cool to rest.”

Limestone tried to shake away the gooey haze that had settled over her vision, but it held fast. Her addled senses had worn down over the course of the afternoon without her even realizing it. Now, brought to the foreground of her thoughts, they were undeniable.

“...f-fine...” She finally acquiesced, “Let’s go in the house. A cup of iced tea would hit the spot I guess.”

Marble grinned merrily, her hands clasped behind her back. They both knew that Marble would be the one serving the tea, thus, a request for it was Limestone’s own special way of showing appreciation for her youngest sister. All the same, the younger Pie shook her head.

“It’s hot in the house,” She replied, and then extended her elegant arm in a gesture of support. “I know a cooler place that I think you’ll like.”

Limestone made as if to ignore the offer of a supporting arm, but wooziness forced her to capitulate. Marble turned her sister about and began marching her towards the path leading down to the rock quarry.

“Huh...?” Limestone blinked, “There are fans and stuff in the house, where are we even going that’d be better than that?”

Marble’s steps were as dainty as the rest of her movements. She eased her sister along, picking out the trail of least resistance down the steep path to the hole below. “You’ll see. Just trust me, okay?”

“Fine, whatever,” Limestone shrugged. “Just so it’s someplace I can sit down for a minute.”

A minute of rest. That’s all she needed.

* * * * *

Limestone followed her little sister into the caverns at the bottom of the quarry that stood several hundred yards below the rest of the Pie family farm. Everything was much as she expected within - the cave walls were slightly damp, adding to the relieving coolness of the shade, while what little sunlight that did stream in was caught by myriad subterranean crystal formations and refracted through the cavern, bathing everything in a cozy, slightly pinkish glow.

Limestone scratched the back of her head and plopped her rump down on a smooth crystal that jutted out from the earth to waist height. She immediately let out a deflating breath.

“Feel better?” Marble giggled, choosing instead to stand, with one hand gripping her opposite wrist behind her back.

“Eh, yeah,” Limestone had to admit, “that helps.” She ran her open palm along the crystal and sought to make small talk, “Good thing the Crystal Empire needs stuff like this so bad for construction, huh? We’ve been in the best business ever since they came back into the world.”

Marble seemed to ignore the comment. Without any hesitation, and much to her sister’s amazement, she stepped over to a formation that was taller and wider than herself, stared at it, and began to slip her spaghetti straps straight off her shoulders. In an instant her plain dress was sliding down the supple curves of her thighs. She let it fall helplessly to the ground, stepped out of it, and began a very casual process of gathering it up to fold it properly and sit it on another crystal to the side. She flexed her straight, thick tail; enjoying its freedom from a dress that did not have a hole to accommodate it.

Limestone nearly fell off her natural stool. “Wh-what are you doing!?”

Marble looked up as if the quip were nonsensical, “Hm? I’m taking my clothes off.”

“I can see that,” Limestone gagged, “Why!?”

Marble lifted her bonnet from her head and tossed it atop her dress like a Frisbee. She shook her long, gray-streaked mane and ran her hands through it, allowing it to float unbidden until it came to rest around her naked shoulders and the small of her back. “To cool off, of course,” She said in her usually diminutive voice. “We share a room and sleep in the same bed. What’s the matter?” Marble was less reserved around her own family, but only just so - that fact alone was enough to make her elder sister cringe.

“Getting naked while you’re changing in our bedroom is not the same thing as getting naked outside!” Limestone complained. “What if somebody sees you!?”

Marble only held her fingers over her mouth and giggled. “Don’t be silly. Who would see?” With that, she spun around in place and stretched her arms over her head, pirouetting on one hoof with a deep sigh as her ample chest swayed along with her. “Mmm, this is much more comfortable on a hot day.”

Limestone pointed, “Uh, where’s your bra?”

Marble giggled again - this time, the sound was slightly condescending. “You don’t wear a bra with a sun dress, silly. You dress in work clothes too much.”

Limestone, incensed, puffed her cheeks into a pout and turned sharply away, folding her arms protectively over her chest. Marble, recognizing the movement, stepped before her sister and stood patiently, arching her back a bit to expose the honesty of her full, nicely-contoured slate breasts and the valley between.

“Come on...” Marble said softly, “We talked about this...it’s not a size competition.”

Limestone huffed.

Marble rocked on her hooves. Her simple, blank panties were so close to her natural color it was somewhat difficult to tell they were there at all. “If it makes you feel any better, Pinkie has us both beat.”

When Limestone didn’t move, Marble decided poking a bit of fun at her absent sister might make her present one feel better. She hopped once, sending a bounce through her bosom, and made a ‘boing’ noise with her lips.

Limestone snerked. “...Pinkie’s got like, cantaloupes on her chest...”

Marble grinned, “Watermelons!”

Finally Limestone returned the smile. “She needs her own holder for her boulders!”

Marble giggled along, allowing Limestone her usual moment of harsh humor. She then sought to demonstrate her point by stepping back over to the crystal formation she had her eyes on before. She pressed her body up against it, mooshing her breasts into it and wrapping her arms around it in a diminutive bear-hug that didn’t even encircle it halfway. Her smile was dreamy.

“Ahhhhhhh....” She exhaled. “This is what I meant by coming down here. You really need to try this. There’s no better way to cool down on a day like today.”

Limestone hesitated, embarrassment prevalent on her darkening cheeks. Marble pressed her own cheek up against the cool crystal and smiled reassuringly at her sister, nodding at another large formation nearby.

“Try it. You’ll like it, I promise. I’ve seen you naked a million times so it’s fine, right?”

Limestone glanced down at herself. Her undone top buttons had been a vain attempt to cool herself off. Beneath them, the cleft of her much more modest bosom waited beneath underwear that suddenly felt rather restraining. Her jeans were too tight, and the more she thought about it, the more she dreaded going back to her toil without truly cooling down.

Trying her best to make the action look mundane, Limestone rose to her hooves and began to undo the rest of the buttons on her checkered blouse. In contrast to her sister, her disrobing had a rough edge to it - her sweat-stained shirt and pants were soon in a haphazard pile in the dirt. She stood there with her arms wrapped loosely around herself, looking uncharacteristically vulnerable in her partial nudity. Upon her supple hip, she bore the cutie mark that shared her name.

“You know,” Marble observed, “I think it’s adorable how much you like frilly underwear.”

Sure enough, Limestone’s breasts and rump were resting within slips of elegant, pink, lacy underthings. The elder sister blushed. “I-I just want to keep things interesting! You wear boring junk all the time, who wants to look at that!?”

“Who’s looking at your underwear?” Marble riposted.

“E-err...” Limestone moved closer to the rock formation, “I just...I can be a girl too, can’t I! Geez!”

Without waiting for a reply, she reached out and brushed her fingers over the cool crystal. The image of immersing her flaming flanks entered her mind, and impulse took her until she too was wrapping herself around the stone, bearing her body for the soothing sensations it offered.

“....ahhhhhhh....”

Marble smiled wanly. “See?”

Limestone hardly cared enough to reply. She mewled and rubbed herself eagerly against the crystal, nuzzling it with the recklessness of one who was new to the practice. She closed her eyes and stood there, hanging on the formation as its sensations enriched her.

Marble uttered a single word that perked Limestone’s ears and stole the swish from her happy tail.

“Daddy!”

With the speed at which Limestone whirled around, it was all Limestone could do to keep from banging her face into another nearby crystal formation. There stood her sister, almost totally naked as if nothing were amiss, conversing casually with the towering spectacle of the Pie family patriarch. Clad in the same black slacks, black suspenders, and white button-down he wore every day, Igneous Rock Pie’s long, gray sideburns and signature short stove pipe hat were unmistakable.

“D-dad!?” Limestone sank immediately to her knees, her hands redundantly covering parts of herself that were already shrouded in lacy underthings. “Wh-what are you doing here!?”

Igneous Rock simply raised a brow at his eldest child as he propped his pickaxe next to a low-seated crystal. “We discussed respective work locations over the table of our bounty this morning, child.” He tilted his head bemusedly, “I would query you for your appearance here as well.”

Marble was rocking on her heels again, a merry grin gracing her cheeks. “I bet you were expecting me on a day like today, weren’t you daddy?”

Igneous smiled warmly. “Indeed, youngest of our flock. Come, greet your sire in the old way.”

Limestone cursed herself mentally for her forgetfulness. Of course father was working in the mines today. She knew that. But then, Marble also knew that...

Limestone put two and two together, turning to her sister, “Wait…you knew dad was gonna be down here, so why did you--”

The words died in Limestone’s throat as the spectacle unfolded before her. Wrapping her arms up and around Igneous’s neck, Marble leaned up on the tip of her hooves and met her father’s lips, capturing them in an open-mouthed kiss whose depth required them both to tilt their heads for space. Marble held the kiss on purpose, staying her father’s eventual attempts to pull away with gentle gripping from her hands behind his neck. When the pair finally came up for air, Marble let out a refreshing sigh and tousled her hair, her tail bobbing happily behind her.

“Mmhmm,” She finally responded to her sister. “I told you I was taking you somewhere you could relax. This is how Daddy and I relax on a busy day when mom’s not around.”

Limestone was so shocked, she didn’t notice her arms hanging loosely at her sides. “...d-does mom know about this...?”

“Hm?” Marble shrugged. “Sure she does. We don’t have anybody but each other way out on this farm silly, and you know how mom is about family.” She glanced ruefully at her father, “The first time Daddy and I started kissing I ended up bent over the kitchen table at three in the morning. Mom walked in on us, got a glass of water, and told dad to make sure to clean up afterwards.”

“Verily,” Igneous chuckled sheepishly, “’Tis true, and I obeyed. Woe betide trying the patience of thy mother, as well you are both aware.”

Limestone’s mouth hung open until she found the wherewithal to form more words. “...and Maud...?”

Igneous tipped his hat back just enough to scratch at his stately forehead. “All of thy kin, whom remain in this place with us, are a family knit by the closest bonds.”

Marble clasped her hands behind her back and dug at the dirt with her hoof. “Daddy wanted to try with you, but we...weren’t sure how you’d take it. We sorta thought you’d just grow into it eventually like the rest of us did.” She looked suddenly apologetic. “I’m sorry...”

Limestone felt stung by the idea that her little sister would be telling her that she would ‘grow into’ something. She waved her arms dramatically and shook her head as if to clear her mind, “J-just wait a minute here…you’re telling me that everybody in our family has sex with everybody else, and I just never knew about it?”

Marble pondered, “Well, not Pinkie. You know how dad got depressed when she left. We were all kinda sad about it really...you remember?” She stepped over to her sister and placed a hand on Limestone’s shoulder. “None of us had ever gone out on our own before. Remember how it felt?”

Limestone said nothing. She looked down, scowling at the memory of her own emotions. She had wanted to lash out at the brightest light in the entire family, as if Pinkie’s moving to Ponyville had been a betrayal. It was a feeling Limestone had long gotten over, but the hole in her heart was a memory not easily forgotten.

“Because of that, we...found a new way to be closer together,” Marble continued. “It just sorta happened, and...well, I guess we should have told you.”

“It’s...it’s cool,” Limestone muttered. She averted her eyes again, keeping them there until she felt her hands being taken by those of her sister. Marble, all soft gray flesh except for her cotton panties, was looking up at her big sister with an expression of genuine concern.

“Are you okay...?”

“...sure, whatever...” Limestone muttered.

“It’s not whatever!” Marble insisted. “We were trying to get over our loneliness, but we forgot about yours.”

Igneous stepped back and folded his arms, staying out of the way of his bonding daughters. Marble drew nearer to her sister, her voice softening to just above a whisper.

“Are you lonely too?”

“O-of course I’m not lonely!” Limestone rumbled, “That’s just stupid...”

Marble Pie, normally such a timid slip of a girl, felt her heart embolden as it filled up with concern for her sister. She took a chance and placed her hand on her sister’s clad breast. Limestone jumped a bit, but Marble let out a soothing coo.

“Shhh,” She encouraged. “It’s okay if you’re feeling lonely. Do you want to play with us?”

Limestone felt a shiver march across her spine as her sister leaned into her. Nose to nose by a mere two inches, Limestone opened her mouth, but no sound issued forth.

“This is okay, to do this,” Marble said softly, searching her sister’s eyes as she kneaded her breast. “I know you don’t even touch yourself or anything like that. You must be really frustrated, and now that I think about it, maybe that’s why you’re even more closed up than you were when we were little.” She tightened her grip on Limestone’s rough hands, “You and dad work harder than any of us. I promise it’ll make you feel great, and it’s really relaxing.” She smiled again, her left eye once again obscured by her long tresses. “Just trust me, okay?”

Igneous Rock was in the process of working the last button on his shirt. He removed it one arm at a time, exposing the chest of a lifelong rock farm worker - hard and chiseled in ways a deciduous farmer couldn’t hope to match. In an attempt to show solidarity with both his children, he stepped out of his pants, underwear, and even sat his hat aside, such that his glistening nakedness was exposed to them all.

“Child,” He said gently. “We will not seek to stay thy course, if it is one of seclusion above all else. But I echo the words of thy sister, and it would...” He cleared his throat, looking, of all things, bashful, “...it would please me to invite you into the deeper depths of our fold.”

An awkward silence ensued. Limestone glanced down at her expectant sister. She felt two pairs of eyes tracing the blue-grayness of her flesh, and in that moment felt more feminine than she had in a long time.

She was a mare. She’d said it herself. She muttered something incomprehensible under her breath.

“Hm?” Marble asked. “It’s okay. What did you say, Sis?”

“...I...” Limestone forced the words out, “...I don’t know how to touch myself...is why I don’t...”

Marble let go of her sister’s hands and slid her arms around Limestone’s athletic waist, running them up her back. She nuzzled cheeks with the elder mare, and finally placed an affectionate kiss on Limestone’s cheek. Marble’s fingers carefully laced themselves into the hooks of her elder’s brassiere.

“Can I take this off?” Marble asked softly.

Limestone hesitated. And then stiffly nodded.

A moment later, Limestone Pie felt the cool kiss of crisp air in a place she’d never exposed outdoors before. Marble was careful not to ogle the older girl’s modest breasts as she cast the bra atop Limestone’s clothes.

“Come on,” She encouraged, “Let’s go see Daddy.”

With one of her hands reassuringly squeezed by her sister, Limestone found herself quickly in the presence of her father. Staring up at him, she considered that both of them were in a greater state of undress in one another’s presence than ever either had seen since before her body began to blossom years ago.

“Uh...” Limestone coughed unnecessarily, “...s-so dad, uh...I mean I don’t need to or anything,” She lied badly, “but, uh...if you need to relax, then it’s fine...”

Limestone felt a thumb and forefinger curl around her chin. Igneous raised her head until the apple green of her eyes fell upon the bright amber of his.

“My child,” He offered, “Eldest and first fruit of my loins. It would be a tiding of the greatest joy to share with you that which brings us all closer together.”

Limestone felt his breath on her as he drew in. She jerked, and Marble’s hand tightened in hers.

“Fear not,” Igneous whispered, “the rewards of our harvest shall be great. Trust in that.”

For the first time, the lips of father and eldest daughter met. The invasion of a writhing, wet object into her mouth was foreign to Limestone at first, but she caught up quickly, encouraged by the need welling inside her that had been denied since the day it first tickled the back of her mind. Instinct took her, and she began to suckle on her father’s tongue as he introduced her to it.

When the kiss finally broke, Limestone had cause to lean on her father’s solid body for support. Marble was there, massaging Limestone’s naked shoulders.

“Shh, take it slow,” Marble cooed. “You’re still exhausted from today.”

Limestone closed her eyes and let out a sigh as her sister worked her shoulders. The elder Pie felt her center of gravity changing, and realized dimly that she was being lowered to her knees by the same hands that worked at her. When she finally opened her eyes again, Limestone was startled and momentarily confused by the sight before her - a part of the male anatomy that she had never before been so up close with. Flared and unexpectedly veiny, the partially flaccid organ jerked slightly with anticipation.

Limestone watched as a tender gray hand slipped from behind her and met her father’s maleness, placating its twitching with a gently caress over his tip. The hand was preceded by Marble herself, who came up beside her sister, also on her knees. Shamelessly she continued to stroke her father’s slowly awakening organ.

“Pretty, isn’t it?” Marble cooed.

Limestone irked, “...it’s awfully big...”

Marble laughed, aware that her big sister had no frame of reference for such a statement. “Aw gee, it gets a lot bigger than this.”

“I-it does...?” Limestone felt her thighs twitching. She wasn’t sure if she was feeling excitement or anxiety. Possibly both.

Marble took up her sister’s hand again and went on, “Don’t worry. It fits in mom, and me, and Maud. It’ll fit in you just fine too.

“I-in...?” Limestone, out of her element now, repeated the word in a hushed tone, “...really...?”

“It’s okay,” Marble guided Limestone’s palm down under her father’s fuzzy scrotum and gently laid his gradually tightening testicles in it. “Just squeeze a little. See how he’s twitching? He’s happy to see you. Show him you’re happy to see him, too.” Marble grinned coyly and nodded at the chest of her elder, each blue-gray breast capped now by a rapidly stiffening, pert nipple. “I can tell you are, see?”

Limestone was too distracted to be embarrassed by her own arousal. She wasn’t unused to smelling her father’s work-scent, but something was different now. There was a deeper musk about it, and as it flooded her every inhalation, she felt an insatiable desire for more. She began to move her hand - testing the weight and firmness of the testicles dangling in it.

Marble backed off, allowing her aroused sister’s curiosity to take over until Limestone had lost herself in clumsily stroking the hardening erection with her other hand. Instinctively she worked the genitals in her hands until her father’s tip was pointing straight out at her nose.

“That’s right,” Marble encouraged as her sister’s face moved closer. “Give daddy a kiss. Like this.”

Marble brought her soft cheek in close. She nuzzled the penis before her, eliciting a jump from it, and slowly made the flared head disappear past her lips. Her reward was a broad hand upon her head, stroking her hair affectionately from above.

“Nnh...” Igneous emitted a grainy grunt, “...you are no less the worse for your learning over time, my youngest...”

Limestone’s cupping of her father’s testicles became more absent as she watched her sister slide down his spire, easily taking him to just past the medial ring before she pulled slowly back in a deep draw. Marble slid all the way off, planting a firm kiss on the tip of the head before smiling again at her sister.

“You try.”

Limestone, huffing with pride, attempted to emulate her little sister’s actions. She gagged somewhere just past her father’s flare.

Marble kept her giggle light and stroked her sister’s shoulder to keep the elder’s natural ire from breaking in. “It’s okay, it’s okay,” she hummed, “the same thing happened to me the first time.” Marble bent herself and leaned in again, until her eyes were watching her sister’s from just overtop the thick erection between them. She ran the tip of her tongue from head to base, her eyes on Limestone, sending a wordless signal as to what the other daughter should do.

Limestone found copying her sister’s actions far easier this time. Soon, both girls were on either side of the twitching girth, kissing and licking up and down while a hand from each of them juggled Igneous’s plump testicles. Cooperation eventually became competition to the elder sister, who was unused to accepting inadequacy. Limestone slipped up to her father’s head again. Swirling her tongue around the bulbous tip, she relaxed this time and took him in slowly, savoring the musky flavor of the organ as it pierced and pacified her. Marble gave way, sliding beneath and busying herself with drawing one testicle into her mouth to greet it with a very gentle squeeze.

“Nngh...”

Limestone felt her father’s hand ruffling her short gray mop. “First from my loins...” He managed, “thy sister is correct. I was encouraged to keep you at a spade’s length from this. I...regret that,” He sighed richly, “...I look forward to plumbing thy depths...”

Igneous grunted again. Marble felt the familiar churn of her father’s testicles, and pulled back from her appreciation of them. She watched Limestone, who had managed to work her way into a shallow bob upon the toy in her mouth, and reached out to gently tap her cheek.

“That’s enough,” She softly dictated. “Let’s give daddy a show before he’s deep inside you, okay?”

Limestone found herself obeying. The greater the swell of arousal in her chest, the more she felt her rough edge softening - she was unused to such tender praise from her father, and she felt herself drinking from his words with a girlish glee she’d long since forgotten.

Marble didn’t hesitate. She cupped her sister’s cheek, drew in, and took Limestone’s lips in the same waltz they’d both shared with their father moments before. Marble led, feeding Limestone her tongue until the elder’s eyes began to lid. She placed a hand on Limestone’s chest and made a show of groping her as she gently encouraged the elder onto her back in the dry, soft silt. Sitting up on her knees, Marble caressed Limestone’s hips, hooked her thumbs around her panties, and began to relieve her big sister of the last of her defenses one leg at a time.

“That’s right…” Marble cooed, “…bend one leg, then the other…you’re doing great…”

Marble rose to her hooves, set her lacy prize over by Limestone’s clothes, and made a show of sensually drawing her own cotton underthings down each thigh. Stepping out of them, she smiled once at her father, flipped her tail up to give him a nice view, and returned to her work.

Marble knelt beside Limestone, who seemed lost in the strange sensation of total nudity while lying prone on the cavern floor. Limestone searched her junior’s eyes, as if to as if she was doing everything right. Marble caressed Limestone’s cheek lovingly, pulled away, and, of all things, climbed atop her sister, straddling her in reverse on her hands and knees. Marble teased Limestone’s forehead with her tail, lifting it out of the way with a singsong giggle to present her sister with a clear view of the slightly weeping opening that waited patiently to be filled.

“Like this...” Marble slid her arms under her sister’s blue-gray hips and pressed her fingers into her yielding inner thighs from below, gently prying her legs apart. She bent her head down and took a deep breath of her sister’s core, sighing audibly.

Limestone, her vision filled only by a slate-gray flower of womanhood, blushed. “H-hey, I haven’t taken a shower...”

Marble ignored the quip and buried her face in her elder sister’s blooming femininity. Worming her nose inside just to savor the deepening scent of arousal, she slipped back out and began to flick her tongue over the nub that contained the center of Limestone’s most tantalizing nerves.

“...a-ahh...”

Limestone jumped, unused to the sensation yet eager to surrender to it. She found herself quickly lost in dizzy warmth, her eyes coming back into focus long enough to find her father, seated on the ground nearby, stroking himself as he enjoyed the entertainment.

“It is kind to reciprocate with thy sister,” Igneous smiled.

Limestone looked confused. Igneous nodded at Marble’s femininity, which was undulating as she rubbed her body back and forth over the girl below her.

“Simply do as she does,” Igneous encouraged, “Share thy joy as it is shared with you.”

Limestone felt the heat rising from her loins as she subconsciously offered her nectar to her sister. Pleasure threatened to white out her mind, but she pressed her face between Marble’s legs and copied her movements, finding the engorged button and kissing at it as she drew her tongue along Marble’s opening, licking it like a frozen treat in the heat of the afternoon. Marble cooed in high pitch, and soon Igneous’s children were lost in pleasuring one another, their collective scent mingling and invading his lungs with mating pleasure.

Igneous Rock sat in the soft dirt with this legs spread and the blunt fingers of his rough workman’s palms wrapped around his foreskin. He kept his masturbation purposefully slow, understanding why his youngest child had kept the oral pleasure to a minimum - it had been nearly a week since their last encounter, and mortal toil had been rough since then. He had a lot to give, and he was a man of sexual temperance – enduring the tease would make the eventual release that much more satisfying for all.

Igneous caught several of the fleeting, mildly embarrassed glances his eldest spared for his spire. He shifted to present himself better, his smile twisting up into a wry grin. “Since the beginning of our deepening family bonds, first of mine,” He said, “I have waited for the day in which we could include thee. It is okay to examine the object of your desire.”

Limestone blatantly stared, watching the throbbing organ as she considered the possibilities. Igneous rose to his knees, erection proud before him, and scooted over to the pair, being sure to keep himself in view of his eager elder child. He placed his hand on Marble’s back and stroked down her spine, passing over the swell of her rump to give it a firm squeeze as he appreciated the frisky flip of her long tail.

“My youngest,” He nudged. “Let us complete the indoctrination of thy sister into the deepest order of her family.”

“Mm?” Marble looked up, considered the words, and grinned. “Oh...mmhmm.”

The passivity in Marble’s voice was more what Limestone was used to hearing from her sister. Marble’s voluptuous form flowed off of Limestone; the younger came up to her knees, and for a fleeting moment, father and daughter shared a kiss from either side of the already panting, blue-gray form below. Marble bent over her sister, allowing her long gray locks to pool over Limestone’s collarbone as she leaned in to easily take another kiss from the bewildered elder.

“Shh,” Marble cooed again as she slipped behind Limestone and rested big sister’s head on her supple knees. Marble began to stroke each of Limestone’s cheeks and smiled reassuringly down at her-

“Daddy wants to take you now, okay? Just relax and let it happen.”

Limestone felt movement between her legs. She gasped when she found her father down there, his hands on both her knees and his penis hovering over her stomach. A bulb of clear, viscous wetness dribbled from his tip.

Limestone balked, “...i-isn’t there...protection or something...? Isn’t that how this works...?” In truth she had no idea, but Marble silenced her with a caress of fingers over her lips.

“Shhh,” Marble cooed again, “It feels so much better natural. U-um...I think so anyway...”

Though the youngest Pie had accepted her father’s gift many times, she had never done so without the protection to which Limestone referred. She had only seen Maud do it once, and as she thought on it, she realized that she had never seen her other big sister quite so...happy, lately. Maud had even cracked a tiny smile at least twice in the past week.

Marble glanced at her father, “Daddy? Why did mom and Maud go to the market today? We have plenty of food...”

Igneous grasped his erection, angling the tip down to kiss against its wet goal. “They embarked upon a visit to the local physician for thy sister. The natural way is better, my child. With it we grow fruitful and multiply. Does it please you think of how thy swell will grow?”

Marble touched her tummy. With hair masking one amethyst eye again, she demurely nodded, “Mmhmm...”

Igneous placed his hand upon Limestone’s stomach and favored her with a glance so warm, she was soothed instinctively by forgotten memories of the first time her father laid eyes upon her.

“And thee, child. You and your sister are ripe, your fields fertile for planting. Say the word, however, and we shall relent.”

Limestone’s green eyes were locked with the bright amber of her father’s. In that moment, she was taken to a time lost to antiquity, where she was the only Pie child - doted fully upon by both of her young and rapacious parents. She didn’t hate her siblings, far from it; but there had always been a small sense of loss in her heart when her mother and father’s attention became divided. She wondered just how much that loss had contributed to the guarded woman she had become.

Limestone placed a hand upon her father’s and drew her equally rough, tapered fingers over his.

“...d-daddy...”

Limestone opened her legs further and nipped at her father’s hard flare with her pulsing, slick walls.

“I am glad of it, my daughter,” Igneous said simply.

The guttural grunt of father mingled with the fluttering sigh of daughter as the two became one.

Igneous leaned forward and allowed his naked penis to slip into a brand new channel. Limestone’s eager muscles bathed her father in silky wetness, gripping and passing him back inside her until his tip kissed quickly at her solid cervix. Fully involved, Limestone arched her neck and nuzzled her cheek into Marble’s thigh, moaning without control.

Marble giggled and stroked her sister’s cheeks anew. “It’s okay, I’m here. Doesn’t it feel wonderful?”

“...ngh...hahh....uh-huh...nnghh...”

Marble giggled, taking the grunting as an affirmation. She ran her fingers through her sister’s hair, petting her affectionately as Igneous planted his hands in the dirt to either side of Limestone and came down atop her. He rolled his hips into a slow pistoning movement.

Limestone cried out with more passion than was necessary and rolled back, matching her partner’s rhythm to the tune of wet squishing. The sound rose from the lubrication produced by her arousal - by her desire to accept her own father’s seed, and the want she harbored for him since those innocent days when he had saved it all for her.

“...d-daa...daddy...nngh...o-ohh...”

Limestone’s head, propped up in her sister’s lap, was in the perfect position for Igneous to claim her lips a second time. He fed her his tongue as he fed her nethers with his breeding spire. The two maintained the kiss until Limestone’s breath became erratic and she turned her head sharply away, grunting with a belated shock of pain.

Marble could tell exactly what had happened. She smoothed her sister’s perspiring brow and comforted her, “It’s okay…that’s supposed to happen…Daddy took mine, and Maud’s too…” She glanced over at her father to explain, “She’s so lost in it, she didn’t even notice you tore her hymen until now, Daddy.”

Igneous smiled and pushed up with his arms, locking his elbows and speeding his thrusts. “Child, it p...pleases me so to take your flower...ngh...soon, you will have the most precious gift thy father can give.”

Limestone kicked weakly, the torrent of new sensations quickly washing away any discomfort. Her eyes rolled as she found her first release, her inner walls spasming with reckless abandon around her father’s organ.

Limestone shut her eyes tightly and bit her lip in an effort to keep her cries under control. She let another slip, and Marble wiped more perspiration from her brow.

“Shhh...that’s it...” Marble whispered, “you recovered fast, you must really want this...feel Daddy inside you...Daddy’s gonna fill you up, he hasn’t even done that with me, yet...”

“I-in...in t-time...child...” Igneous muttered. “...ah, first of m-my daughters...your womanhood is...unique among thy kin...”

Limestone had given up her attempts at control. She gave herself over to her cries and allowed the passionate din to echo through the cavern, reverberating from each crystalline structure that would one day serve as foundations for a new neighborhood in the distant Crystal Empire. The loss of control over her voice exploded through her, forcing her to give way to a climax that rolled into a second so fast that she couldn’t be certain if they were even separate events. Her hips ground against her lover’s; her arms rose, her fingers lacing tightly about his neck as she pressed him as close to her heart as she could manage. Words she wasn’t certain she would remember afterward broke forth-

“...d-daddy...o-oh daddy, p-please nghh...I-I wanna be with you t-too...f-fill me up...m-make me h-heavyyahhh...!”

Marble blushed.

With a powerful grunt, Igneous answered the call of nature and thrust as deeply as he could into his daughter. With his tight sack brushing her perineum, he allowed burst upon burst of his sticky, thick affection to find its way inside her. Unprotected and free, he bred his child to the shared chorus of a feral whinny between them that melted into a tender kiss.

Marble gently sat Limestone’s head on a pile of clothes and slipped out from her, the desire to rub herself now too strong to ignore. She casually spun her fingers over her nub as she watched her father pump and pump again into her sister. The release lasted for some time, as Marble expected, ending only when Limestone’s womb was overfilled to the point of stretching – leaving the blue-gray young lady with what Marble felt was an adorable faux-baby bump.

Igneous brushed Limestone’s hair aside and gathered her shivering form in his arms, bringing her along as he collapsed onto his side.

“You are well, little one...well and safe with thy father...”

Limestone tried to summon up her usual brashness, but found herself as naked emotionally as she was physically. No longer caring who might see, she rested her head against his barrel chest and slowly caught her breath, her voice higher and softer than any of them had heard in a long time.

“...d-daddy...”

Marble shifted her weight, reclining on one hand planted into the dirt. Her father looked up, but she only shook her head as she openly masturbated, a bright smile on her lips.

“It’s okay Daddy. Be with her for now. She needs this.”

Despite her self-coitus, Marble rose and padded daintily over to kneel behind her father. She laid down behind him, pressing her breasts up against his back and circling her arms around his waist. She lay there, providing her soothing warmth to the couple in afterglow, content most of all that they no longer had to hide their lovemaking from a beloved member of the family.

Marble brushed her fingers over her big sister’s swollen tummy. “If you take,” She whispered, “you’ll grow a beautiful bump just like this. Won’t that be wonderful?”

Igneous Rock Pie and Limestone Pie sandwiched the former’s erection between them. Still oozing fertile seed, it twitched once again against the feminine softness of its new best friend.

Limestone, of all things, giggled in reply to her sister. Feeling ten years younger, she rubbed her cheek against the chest before her.

“Mmm...daddy...you’re still hard...”

“Indeed child,” Igneous cooed back. “There is so much more to come.”

The day was long, exciting, and thoroughly exhausting in a brand new way.

Growing Season

Limestone Pie tied to recall a time when the taste of her father’s lips had not been so familiar.

Locked in one among thousands perfect moments with them now, she closed her eyes and thought back, shuffling through her memories for the day she first entered the deepest fold of her family.

Five months? No...six.

With her cunning grin restored, Limestone knelt in the soft silt of the family crystal cavern, naked as the time of her birth and not the least bit ashamed of it. She clasped her father’s hand in hers, placing it over her heavily swollen tummy. The extra weight had become familiar, as had the twitching feeling of the small life that blossomed within.

“Feel him kicking?”

Igneous Rock Pie, his solid, amber body bared to the elements just like that of his daughter, pressed his hand to her belly and reveled in the sensation.

“Indeed, my child,” He grunted, perspiration evident on his brow, “Soon to be mother of another of my children.”

Limestone snerked. “Yeah, well you better be a good dad, Dad!” She reached down to stroke the straight bangs of her youngest sister Marble, who was laying on her back with her head in Limestone’s lap. “Looks like it’s your turn now, huh?”

“Mmhmm…”

Marble allowed her sister her smugness. In the span of a few short months, Limestone had gone from totally un-indoctrinated to acting as though the inter-mating of her family had been her sole founding notion, but Marble expected that from her. In recent months, Limestone had been lighter and airier than ever Marble had seen her before. If it made her sister happy to feel that way, it was enough for Marble not to question it.

All the same, Marble couldn’t help getting in a jab of her own. Her hands on her breasts, she pushed the fleshy orbs together and returned to the cool enjoyment of watching the tip of her father’s erection emerge from, and vanish again into her cleavage. Marble blew on her bangs and grinned at her sister with a certain smugness of her own.

“Yeah, yeah, whatever,” Limestone rolled her eyes, “My boobs are so swollen I could totally do that now. I just don’t want to.”

“Mmhmm,” Marble sang.

“I could!” Limestone insisted. “See how you like morning sickness when you’re going through it in a couple weeks!”

Igneous broke up the playful trading of jabs with a sharp grunt. “...i-it is thy time, my youngest...l-let us begin...”

Marble lit up with an eagerness that would have done her elder sister Pinkie proud. She wiggled her naked rump in the dirt as her father got off of her and found a comfortable crystal upon which to prop himself up. His dribbling erection stood proud, presiding atop two suspended testicles that were heavy with his seed.

Marble got up on her knees and touched two fingertips to her lips. Limestone, who was already settling in for the show, drew her fingers over her belly, down to her weeping flower, and spoke first.

“Wow dad, you really store it up when you haven’t cum in a few days.”

“It is best to maximize volume,” Igneous commented, allowing Marble her moment to appreciate his impending gift to her, “In this way, we shall ensure a successful coupling.”

Marble was on her hands and knees, her breasts dangling beneath her with the pull of gravity. They swayed as she moved, and at length she crawled the distance to straddle her father’s hips. She leaned in to share a kiss with him and then drew up to his ear for a whisper.

“I’m ready daddy. Make my tummy grow, like Limestone and Maud...and mommy too.”

Igneous shuddered and placed his hands on Marble’s hips, guiding her wet, weakened petals to their piercing. “Thy way with words has never ceased to entice your father. I have waited for this day-” He glanced over at a heavily pregnant Limestone, who had propped herself up for a lengthy masturbation session, “-as much as I waited for thee, eldest of my house.”

“Tch,” Limestone, already rubbing herself, took in a sharp breath and let it out with a fluttering of her lungs. “...wh-whatever d-dad,” She joked, “Y-you know I’m just gonna have to run the nursery. Like I run the farm already.”

“...o-ohh...”

Marble closed her eyes and rolled her face to the cavern ceiling as she sat slowly down, impaling herself on her father to the hilt. When her hips came to rest against his, she let out a delicious whimper and bit her lower lip, wasting no time in seeing to her female needs. She began to roll atop him, inviting his penetration and the rhythmic kiss of his penis tip against the entrance to her womb.

“...hahh...s-so deep, D-daddy...”

Igneous felt the frisky thumping of his daughter’s tail dusting his legs as she moved on her own, lathering him in welcoming pleasure. He knew that this was good for her - that the shy bubble she drew around herself in the presence of outsiders would deflate bit-by-bit with every time she bore her naked breast in practice with her own kin.

“Ngh...child...due to the attentions of th-thy ample, soft breasts...I have not long before issuing thy gift, even as we begin...” He punctuated his appreciation for Marble’s curves by reaching out to grip each breast, rolling the erect nipples that capped them between his fingers.

Limestone couldn’t help herself, though she too was beginning to lose composure as the weeping of her opening became audible. “...h-heh...my boobs get sore yanno...g-gonna make you rub ‘em later dad...”

But the coupling of father and daughter was beyond hearing her words. Riding her father like the breeding stud he was, Marble pushed out her chest for him and rested her hands on her thighs, bouncing her body with loud, fleshy slaps against his.

“O-ohh Daddy...nghahh...n-nothing between us this time...” Marble began to pant, “...p-plant your seed deep...s-so it takes...”

Igneous had no intention of denying his child her reward. He sat back, hands returning to her hips to control her speed as she gripped him. He glanced between his two beautiful children - each lost in stimulating her own blossoming womanhood.

“...ahh!” Marble instinctively brought her hands to her breasts and took over the kneading her bouncy flesh, “...o-ohhnngh...g-gonna...oh daddy...!”

Igneous felt the familiar, reckless grasping of a vagina in orgasm. Just before he yanked her down to pierce her to the core, he thought about the old adage, and knew now that he could confirm it - mothers and daughters really did feel alike.

Erupting like Vesuvius, he shot forth rope after rope of his virile semen into his daughter, seeding her womb for the first time. His churning testicles saw no quick end to their release, and it wasn’t long before Marble’s slight, virginal womb grew convex and pushed out.

“...v-verily m-my child...” Igneous collapsed backwards as his testicles emptied and afterglow began to spread through his mind. “...I sh-shall enjoy watching you grow heavy along with your s-sisters...”

Marble tried to catch her breath. Limestone, panting in her own right, came up beside Marble and borrowed a small kiss from her lips. Blue-gray hand guided slate gray down to Marble’s ashen tummy, where the two enjoyed the stroking of the younger sister’s new love bump.

Limestone nipped one of her sister’s flicking ears. “Gonna be fun being all knocked-up with you Sis. Especially the second time around.”

Marble sighed dreamily. Making no attempt to disconnect herself from her father’s love, she leaned against her elder sister and came to rest.

“...next time Pinkie visits, it’s gonna be so much fun...maybe daddy will even send her home with a bump of her own...”

“Heh,” Limestone ruffled her sister’s lush locks. “Maybe so. Thanks, by the way. For all this.”

“Don’t worry,” Marble closed her eyes and smiled honestly, “I won’t tell anybody you said that. I love you.”

“Yeah,” Limestone managed to admit, “…love you too.”

The October sun shone unusually warm upon a field of fertile rocks, ready for the harvest.
