Chapter 2

“I can explain?” Pinkie Pie muttered weakly, wincing as she noticed a particularly large rivulet of seed drip down her mother’s shocked features.

The older mare blinked, dabbed a hoof against her face, and pulled it back, staring at the thick wad of seed that now stained her hoof as well as her face. As she continued to stare, her mind barely able to parse what had just happened, Pinkie continued to panic.

“Oh please don't be mad I was just really pent up and I was thinking about Marble and then-” The party pony groaned and slammed a hoof against her forehead. “Dammit Pinkie admitting you had incesteous thoughts about your sister is not helping!”

Cloudy Quartz didn't even seem to notice the increasingly panicked tone in her daughter’s voice as she continued to stare down in shock, only to look down at Pinkie’s somehow still hard erection. “Your still hard.” The older mare muttered weakly.

“I er, yeah?” Pinkie remarked. “It takes a few times before it finally settles down and- augh!” The party pony yelped, trying and failing to turn her body in such a way to hide her erection from her mother. “That's not important now mom!”

“I wouldn't say that, it seems quite important if you were willing to beat off on your mother’s face.” Cloudy replied with a smirk.

“Uh… what?” Pinkie muttered, her jaw hanging open as realization settled in.

“I’m just saying it seems like it's more important than you first let on, if you were willing to do that, while thinking of your sister.” Cloudy Quartz remarked with a shrug, her tongue slipping out of her mouth and licking up the wad of seed on her hoof. “Mmm, that's pretty good. Your high sugar diet has done wonders for your flavor my dear.”

“Who are you and what have you done with my mother?” Pinkie asked, whilst glaring at her parent.

The older mare shrugged, gulped down the cum sitting on her tongue and looked back at her daughter. “This is me, the real me I guess you could say.”

“Are you sure your not just the worst changeling in the history of ever?” Pinkie asked, evidently only half joking.

If Cloudy Quartz was annoyed about the comment, she didn't show it. “I became a different mare when I married your father, and after we split up I could finally be me again, I am sorry if it's that different dear, but I swear this is me.”

Pinkie Pie glared down at her mother’s cum covered features for a few more seconds before her face softened suddenly. “It really is you. But since when were you a… well how do I say it?”

“Cum slut?” Cloudy Quartz offered, making her daughter blush and her cock twitch, something that the older mare took close note of. “I suppose you could say it all started oh… how long ago was it since you and Marble fucked behind the tool shed again?”

Pinkie Pie’s open jaw slammed shut. “Eight years and four months.” She muttered.

“Ahh yes, about then you could say.” Cloudy Quartz used her hoof to gather up another load of cum, which she pushed into her mouth and swallowed after giving it an ample amount of time to roll around on her tongue. “On the day I found out two of my daughter’s little secrets I began to question the dogma your father had placed upon this family.”

“B-but I thought you two were both, well, you know.” Pinkie Pie muttered before making an exaggerated stern and neutral expression.

Cloudy Quartz giggled. “Oh Pinkie, sure I may have been that way when you were younger but after that fateful day the cracks had begun to show and I started to open up more, despite your father’s misgivings.”

Pinkie Pie rubbed her chin thoughtfully, trying to search her memory for a time where her mother could have done something close to ‘opening up.’ After several seconds of silence, Pinkie Pie began to remember all the small, almost imperceptible things Cloudy Quartz had done and said to her over the years which lay outside what Pinkie considered normal for her mother. “Oooh, so that's why you visited Ponyville without dad all those times!” She exclaimed excitedly.

Cloudy Quartz nodded. “He never condoned visiting you kids. He always said that entering your life was a ‘sure fire way to make them dependent on you.’” The older mare snorted and shook her head, the glasses hanging around her neck shifting soundlessly. “Which is obviously rubbish.”

“Wait a second, that doesn't really explain why your suddenly okay with, well, all this.” Pinkie Pie remarked, gesturing from her crotch to the older mare’s seed covered face.

“Oh Pinkie dear, it's simple.” The older mare smiled and took a tentative step forward. “I have feelings for you, and have had those feelings since the moment I saw you and Marble behind the shed.”

“Well yeah your my mom you have to love me!” Pinkie Pie half asked, half stated.

“Oh I love you alright.” Cloudy Quartz whispered huskily, taking another step forward, her muzzle mere inches from Pinkie Pie’s.

“I love you too mom.” Pinkie Pie said with a wide, nervous smile.

Cloudy Quartz rolled her eyes. “Not like that Pinkie, I mean love love.”

“I don't get it.” Pinkie Pie replied, her brain trying to reject what she already knew.

The older mare sighed, rolled her eyes once more, and took a step forward, pressing her lips against Pinkie Pie’s. The pink pony stood there in shock for nearly three seconds before her body seemed to move on it's own, parting her lips and allowing her mother’s tongue to enter her mouth. Both mother and daughter closed their eyes, their hooves reaching around one another’s neck as they fell into a kiss that was as passionate as it was overdue.

Slowly, after many minutes, the two parted once more, with the mare’s sharing an intense, and longing gaze that stared deep into one another’s eyes. “Wow.” Pinkie Pie muttered. “Your face is a mess.”

Cloudy Quartz giggled, leaned forward and planted another light kiss on Pinkie’s lips. “Thanks Pinkie, you look great too.”

“Well I mean you do look great too, but wowee that was a big one.” Pinkie Pie explained.

Taking a step back, the mother and daughter separated reluctantly, with Cloudy Quartz using her hoof to clean her face as much as possible. “You know that's the first facial I’ve ever received, your father was so very vanilla.” She commented.

Making Pinkie’s cock twitch against her barrel, and an excited grin to come to the pink pony’s face. “Really?”

“Oh yes. I don't think we did more then three positions our entire marriage.” Cloudy sighed. “He wasn't bad in bed either, just boring, I suppose.”

“Can we maybe, not talk about dad and his bedroom preferences, please?” Pinkie asked, wincing slightly.

“I’m sorry dear, how ever can I make it up to you?” Cloudy Quartz smirked and leaned a little closer. “Perhaps a blow job is in order?”

Pinkie Pie gulped, and raised a hoof, keeping her mother at arm’s length for the moment. “I need to know something first.” She demanded.

Her mother raised an eyebrow at the pink pony’s sudden seriousness. “Go ahead dear.”

“Was I…” Pinkie Pie gulped, and looked down. “Was I the reason you two divorced?”

“Oh Pinkie, my sweet, sweet girl.” Cloudy Quartz whispered, leaning forward and wrapping her hooves around the younger mare’s shoulders. “It was never your fault. You merely sparked an old flame in my heart that I had long since forgotten about.”

“B-but if Marble and I never-” Pinkie Pie began, only to get cut off by a gentle hoof against her lips.

“Be silent, my daughter. If it did not happen then, it would have happened eventually, but with something else. My little awakening was coming, whether you were the one to spark it or not.”

Pinkie Pie gulped heavily, wiping away a stray tear that threatened to slip down her cheek. “Are you sure?”

“Super sure.” Cloudy Quartz declared sternly.

For a moment the mother and daughter simply stared at one another, before the edges of Pinkie Pie’s lips slowly lifted and a wide smile spread across her face. A smile that suddenly vanished when Pinkie Pie gasped dramatically. “Oh my gosh, do you know what this means?”

Cloudy Quartz blinked. “That you no longer have to sneak away in order to jack off all over the crystals in the south field?”

“Well I mean that too, but also, you must be totally pent up since dad left!” Pinkie Pie grinned, and threw her forelegs around her mother’s neck. “How long has it been, like two, three months since you had some fun?”

The older mare paused suddenly, tapping her chin with a hoof as she stared up at the sky. “Nine, maybe ten months, I think.”

Once more, Pinkie Pie’s jaw hung open, only for the party pony to gain a stern look as she shook her head. “Oh that will simply not do one bit. When was your last heat?”

Cloudy Quartz shrugged. “A weak ago. Why?”

“That means your safe, good.” Pinkie Pie grinned. “Lets fuck.”

“What like here?” Cloudy asked, some of her confidence evaporating.

Pinkie Pie nodded vigorously.

“Like right now?” Cloudy asked again.

Again, Pinkie Pie nodded, this time even more vigorously.

“Well I…” The older mare paused, looked into her daughter’s eyes and shrugged. “Aww what the hell, lets do it.”

Chapter 3

“Well I…” The older mare paused, looked into her daughter’s eyes and shrugged. “Aww what the hell, let's do it.”

“Yes!” Pinkie yelled, pumping a hoof in the air. “Now, we gotta go quick, I’m supposed to help Maud in the mines in a few minutes.”

“Err okay, how do you want me, than?” Cloudy offered, pushing her glasses further up her nose.

“As much as I would enjoy that blowjob you mentioned, I’m afraid that just ain't gonna cut it.” Pinkie Pie declared, while shaking her head.

“R-really?” Cloudy blushed and glanced down at her daughter’s lengthy erection. “I knew you were prodigious, but this amazing. How many times can you ejaculate in a single day?”

“My record is twenty one! But I was suuper backed up then, now I’m just really really backed up.” Pinkie Pie replied, grinning confidently.

“That is… quite something.” Cloudy Quartz murmured, her gaze locked on Pinkie’s throbbing cock.

“Anyway, we gotta boogie if we want to do this, so just bend over however and let me do everything else. I’ll make you feel like a million bits, I promise!” Pinkie declared.

“So just anywhere? Okay then.” Cloudy remarked, the pony’s heart already pounding in her chest from the sheer debaucherous nature of such an act.

Here they were out in the middle of the field pretty much, with only a slight hill to obscure them from sight, and they were about to have sex. Despite all of her wild fantasies, Cloudy Quartz never assumed she would actually do something like this. Yet here she was, casting aside her glasses, and bending over, her body ready to receive her daughter’s rock hard cock.

Pinkie Pie gave an appraising whistle at the sight of Cloudy Quartz’s glistening marehood. “Wowee mom, you are sopping wet down here!” Pinkie Pie declared, her hooves gripping the elder mare’s flanks tightly.

“The sight of your cock is rather erotic. In fact your both longer and thicker then your father by a wide margin.” Exclaimed the elder mare, who was furiously blushing as she felt her daughter play with her butt while getting an unobstructed view of her privates.

“R-really? That's kinda hot in a weird way.” Pinkie Pie replied, only to shrug. “Alright mom, get ready for the Pinkie train, cus here I come!”

Cloudy Quartz didn't have time to wonder what the pink mare meant by such a statement but she was about to find out that it meant her daughter was about to thrust into her with all the force of a train. The party pony mounted her mother, and buried herself in the older mare’s snatch in a single leaping motion, bottoming out her cock into Cloudy’s cunt in a single powerful thrust. For a moment the older mare didn't know what to make of it, too shocked by the sudden penetration to be capable of thinking of anything at all. Then the pleasure hit, and her knees became weak, her legs wobbled, and for a moment she thought she was going to fall over.

Her earth pony resistance quickly kicked in though, and she stood back up just in time for Pinkie to begin to move. And move she did, thrusting her hips with such speed and power that Cloudy Quartz could hardly feel when one thrust ended and the other began. It was akin to getting fucked by a machine set on the highest setting, as Pinkie Pie never slowed, and easily plowed past the meagre resistance Cloudy’s unused pussy put up.

Years of kegel exercises and tightening back up after bearing her daughters meant nothing to the hyperactive pony who plowed the elder mare’s pussy with all the speed of a pony possessed. Before Cloudy Quartz knew it, her mind was awash with pleasure, the mother of four finding herself arching her back instinctually, and lowering her head submissively, allowing Pinkie a better grip. Which the party pony instantly took advantage of, her superior weight and size dominating the elder mare as her forehooves gripped Cloudy’s waist tightly.

The already potent scent of sweat and sex grew ever more present, made worse by the fact that Cloudy Quartz found herself face to face with the wasted seed Pinkie had spilled earlier. Though Pinkie Pie was relatively quiet, only uttering an odd grunt here or moan there, Cloudy Quartz couldn't help but moan loudly, and unabashedly. It was simply too good, the pink pony being everything her father wasn't, passionate, fast, big, and above all, powerful.

“Oh god Pinkie, I’m about to cum.” Cloudy Quartz whispered.

“Me too mom, can I cum inside you?” Pinkie asked, her pace never slowing for even a second.

“S-sure, just cum nice and deep so I don't leak everywhere okay?” Cloudy replied, already looking forward to seeing what the pink pony’s load felt like inside her.

PInkie Pie saluted. “Can do mom!”

In an instant Pinkie Pie’s thrusts became even faster, hit even harder, and seemed to penetrate even deeper. Cloudy Quartz was once more nearly knocked from her hooves, Pinkie’s cock filling every last inch of space in the mare’s cunt. Within seconds, Pinkie came, and a milisecond later, Cloudy came as well, with Pinkie suddenly lurching to a stop and falling limp on Cloudy’s back.

“Oooh yeah, that's the stuff.” She whispered, tongue lolling out of her mouth.

Cloudy Quartz would have laughed at the sight, but found that her orgasm rendered anything other than moaning whorishly to be an impossible task. Something Pinkie did as well, until her orgasm finally died down and she stopped painting her mother’s insides with her cum. Then, the pony shook her head and cracked a wide smile, giving Cloudy Quartz’s butt one last firm smack, her orgasm having just barely died out finally.

“That was great mom! Do you mind if I sneak into your room and fuck you a few times later tonight?” Pinkie asked, as she dragged the massive, flared head of her cock from Cloudy’s gaping hole.

“You can fuck me however you want, whenever you want.” Cloudy replied dreamily.

“Great! I’ll see you later!” Pinkie announced before kissing her mother on the cheek and bouncing away.

Cloudy Quartz merely stood there for a few minutes, feeling her daughter’s thick, nearly gel like cum drip from her distended hole and join a growing pool that formed between her back legs. “That was the best lay of my entire life.” She muttered, a whimsical expression on her face.

The next day.

“Mmf, fuck mom your throat is tight.” Pinkie Pie whispered, the party pony grunting as she her mother gobbled every drop of cum that shot from her dick and straight down the elder mare’s throat.

Below the wooden table Pinkie Pie sat at, Cloudy Quartz kneeled, keeping her muzzle pressed firmly against the pink pony’s crotch. Silently delighting at the sensation of Pinkie’s cum shooting into her stomach, adding to the growing lake in her belly. That load joined two others she had already swallowed today, quite a feat considering breakfast was technically not even over yet. Not like Pinkie Pie was any rush though, and she had long since forgotten about her bowl of cereal in order to focus on her mother’s tight throat.

That was until she heard the sound of hooves coming down the hall. “Someone’s coming.” She hissed, before sliding her chair forward and wolfing down a mouthful of cereal.

Cloudy Quartz could do little at this point, and the mare merely remained locked with her face pressed into her daughter’s crotch, cum still shooting into her belly. She hoped the table cloth was enough to hide her form, because she wasn't about to move while there was cum left to drink.

Marble appeared in the doorway, the pony raising an eyebrow at her sister who still sat alone at the kitchen table. “Are you still eating Pinkie?” She asked.

Pinkie Pie nodded, before swallowing hard. “It's really good, so I decided to have seconds!”

“Well okay… Maud asked if you could help in the east field again, she said something about the light not being very good over there.” Relayed the younger pony.

Pinkie Pie nodded a little too enthusiastically, nearly knocking over her bowl with her bobbing head. “I’ll be there when this is done!” She replied.

Marble looked at the now empty bowl, and back to Pinkie Pie before shrugging and walking away.

Leaving an exasperated Pinkie Pie to collapse to the table. “That was close.”

Cloudy Quartz rose from her hiding spot, wiping away some cum that had dribbled down her lips. “You are a terrible liar, my daughter.”

“Augh I know. I’m even worse than Applejack.” Lamented Pinkie, who was currently squishing her face against the wooden table.

“Don't worry about it, dear, I’ll see you at tea time, right?” Cloudy inquired, while fixing her mane in a nearby mirror.

“Yupper doodle! You better have room in that womb of yours because this time I’m putting way more then two loads inside you!” Pinkie Pie declared, before hopping up from the table and dashing away. “Later mom!”

“Have fun!” Yelled Cloudy Quartz, who sighed contentedly while absently rubbing her belly. “Stars above, my daughter is hot.”

“Wow Pinkie, I didn't even know you could do that thing with your tongue. You have to teach me that one.” Cloudy Quartz whispered as her and Pinkie Pie trotted down the hall, smirking all the while.

“Maybe tonight when we go back to our bed, I'll show you how.” Pinkie Pie replied, bumping her sweat stained hip against her mother’s equally as sweaty hip.

“Oh Pinkie.” Cloudy Quartz murmured, the mare’s cheek bright red and blushing profusely from her daughter’s words.

Turning a corner, the two came face to face with two other ponies who were just as sweaty as they were. Both Marble and Limestone Pie were walking towards the exact door they were, both seemingly talking about something heated, and secret. That conversation dropped the second the two groups of ponies met one another and they stood there, staring at each other for several long seconds until Pinkie Pie broke the silence.

“Were you girls heading to the showers as well?” Asked the party pony.

The two other ponies looked at one another, with Marble gulping while Limestone seemed temporarily shaken. “Err yeah.” Limestone muttered. “I was gonna let Marble go first though, isn't that right Marble?”

“Yeah, totally.” Marble muttered before hastily shuffling into the bathroom and closing the door.

Leaving the three other mares to all stare at one another, Pinkie Pie unable to sense the air of unease at all and merely bouncing on her hooves, grinning. While both Cloudy Quartz and Limestone stared at one another, sizing each other up in silence. Until that is, Pinkie Pie broke that silence once more.

“So whos next? Cus if it's okay with you two I totally call dibs.” Pinkie Pie half declared, half asked.

“Go ahead dear, I think I’m going to go check something in the kitchen for now.” Murmured Cloudy who gave Limestone one last look before turning and leaving.

“I’m going to go see what Maud is up to, you can go ahead Pinkie.” Offered Limestone.

Pinkie Pie shrugged. “Okie doke, see you later.” Watching her other family members leave, Pinkie Pie pondered what the weird glares they were trading meant, only to shrug once more. “They must have been really disappointed they couldn't go next, maybe we should build a second bathroom or something.”

Rolling off her mother, Pinkie Pie sprawled onto the elder mare’s bed, limbs splayed in all directions as she panted profusely. A level of exhaustion that Cloudy Quartz seemed to share as well, as the mare lay on her back, legs splayed, save for a forehoof which rested on her bulging midsection. The limb moved in slow sensual circles, the mare staring down at the rippling mass of cum barely contained within her body.

“You truly are remarkable Pinkie Pie. I’ve never heard of another pony making this much seed before.” Cloudy Quartz complemented.

“I only make so much cus your so sexy.” Pinkie Pie replied, kissing her mom on the cheek. “Say, why don't you call me Pinkemana anymore?”

“I know you prefer Pinkie Pie, so why wouldn't that be what I call you?” Cloudy replied simply.

“Huh.” Pinkie Pie smiled. “Thanks mom, I really appreciate it.”

“No problem darling. Now you really must be getting back to your own bed, your sisters are going to grow suspicious if you spend another night ‘on the couch’.” Cloudy Quartz reminded, gently giving the party pony a push to her shoulder.

“Nah, they don't suspect a thing. I’m like, super sneaky.” Pinkie Pie shot back with a giggle.

The levity they both felt vanished the second they heard the door creak open, revealing Marble standing there awkwardly, half her face hidden behind her mane. “Actually Pinkie Pie, your about as sneaky as a landslide.”

“How did you know I was here?” Pinkie Pie asked. “I made sure to sneak out my window and everything!”

Marble rolled her eyes. “You didn't even close the door all the way.” As if to accentuate her point she pushed the door open a little wider.

Cloudy Quartz sighed and planted a hoof into the middle of her forehead. “We are going to have a long talk Pinkamena Diane Pie.”

The pink pony tugged at a collar that wasn't there, wincing under the combined look of both her mother and sister. “Whoops?”

Chapter 4

The pink pony tugged at a collar that wasn't there, wincing under the combined look of both her mother and sister. “Whoops?”

“Whoops is right you silly filly.” Cloudy exclaimed before beckoned her other daughter with a hoof. “Come here Marble, and close the door. We can talk about this once we make sure your other sisters won't accidentally walk in on us.”

“Yes mother.” Marble replied weakly, trotting inside after carefully shutting the door firmly behind her.

“There we are. Now Pinkie, would you be a dear and make sure it's locked before you come sit next to me?” Cloudy Quartz commanded.

“Yes ma’am.” Pinkie replied quickly, snapping a salute before locking the door and leaping onto the bed across from her mother.

Marble meanwhile was so distracted by her mother’s bulging midsection that she could only sit on the edge of the bed and stare at her very large belly. “Mom, are you pregnant?” She asked hesitantly.

“No, your sister just produces quite a bit of seman.” Cloudy replied. “I’m much too old to have children anyway.”

“That explains why you guys don't use a condom.” Marble muttered.

“Plus it feels really good raw.” Pinkie Pie added with a salacious wink to her mother. “And I just love pumping mom full of cum.”

Cloudy Quartz rolled her eyes and put a hoof on the pink pony’s shoulder. “I don't think Marble wants to hear about that kind of thing.”

“Oops, sorry Marble.” Pinkie Pie apologized quickly.

“It's okay.” Marble whispered. “Limestone always wears a condom, so I am kind of curious.”

Pinkie Pie gasped. “Wait, you and Limey have sex?”

“That explains quite a bit.” Cloudy Quartz murmured while tapping her chin.

“Y-yeah. She gets really pent up sometimes, but she never produces this much.” Marble remarked in awe, a hoof prodding her mother’s jiggling stomach. “How does it feel?”

Cloudy smiled faintly, a hoof continuing to rub her shifting, sloshing stomach. “Really good, and very full. If I sit still it almost feels like I’m pregnant all over again.”

“Woah.” Marble muttered, her hoof going to her own belly and rubbing the flat surface idly.

Pinkie Pie grinned proudly. “Plus mom cums like crazy when you stuff her so full of cum that it shakes when she walks.”

The elder mare blushed profusely. “It does feel quite remarkable to be so full. It helps that Pinkie is such a big girl.”

“She is, isn't she?” Marble muttered.

“Soooo.” Pinkie murmured while sliding closer to her sister. “Why did you walk in on us if you knew we were busy doing the vertical mumbo?”

“The vertical what?” Marble replied, dumbfounded.

“She means sex, dear.” Cloudy Quartz interpreted.

“Oh um, well you see I…” The younger mare looked away, her cheeks becoming bright red.

“You wanted to join us, didn't you?” Pinkie Pie announced suddenly, gripping her sister around the shoulder. “And now you want to look just like mom.”

“...Yes.” Marble whispered, her hooves covering her face.

Cloudy Quartz shook her head and gently pushed Pinkie Pie aside, allowing Marble some manner of personal space. “Don't let Pinkie Pie pressure you dear. Is that why you were really here?”

Pinkie Pie was about to dispute her mother’s assurance, but a harsh glare from the older pony silenced such words before they even left her mouth.

Marble, unaware of this interaction, nodded slightly. “Limestone has been busy lately, and after I found out about you two, I couldn't help but think back to that time all those years ago.”

Pinkie Pie blushed hard while a wide smile slowly crossed her face. “Really? I thought you regretted it though?”

Marble shook her head. “I didn't know what was happening in the moment. It was my first time and I came so hard that my legs went numb and I was convinced that if I did it with you again I would get paralyzed.” The mare shrunk deeper into her mane, her blush deepening. “I know it's stupid, but after hearing all the sex is bad stories from father I was scared.”

Cloudy Quartz sighed, and gently tugged her daughter into a tight hug. “Shh now, it's okay. We all believe silly things when we are young, even me.”

Marble wrapped her hooves around her mother’s midsection and sniffed. “R-really?”

“Yes.” Cloudy declared, a soft smile crossing her face. “I was convinced that if I didn't wake up in time for chores every single day that my mother would kick me out of the house. After I got sick, I learned that the stories she told of bad things happening to us foals were just stories meant to scare us and make sure we listen to them.”

“That's silly, why would she kick you out? Granny Pie was super duper nice.” Pinkie Pie asked, the party pony laying on her chest, her hooves under her chin.

“Granny Pie was still married to her first husband then and he wasn't a very nice pony.” Cloudy declared sadly. “After they split she became much nicer, and much easier to talk to. A lesson I should have taken to heart, in retrospect.”

“You were never that bad mom!” Marble declared. “No matter what I always knew you loved us.”

“Totally.” Pinkie Pie added confidently.

“Daww you girls are the best.” Cloudy replied, squeezing the shoulders of both mares at once, resisting the urge to hug them both for obvious reasons.

“So, you wanna join us in family fun times from now on? Cus I’m still preeeety pent up if you want to go a round or six tonight.” Pinkie declared while leaning close to her sister and flashing her a wink.

“Well I wouldn't mind, but I don't want to step between you and mom’s alone time.” Marble replied nervously, glancing over at her mother expectantly.

Who merely waved off the concern with a dismissive hoof. “Oh dear, Pinkie Pie has already packed me full of cum. I doubt I could even go another round without falling over.”

“So do you mind if we er, do it here?” Marble asked, tapping her forehooves together. “Cus Maud and Limestone were already asleep and I don't want to sleep there tonight. Limestone always gets mad if I wake her up.”

“Aww she's just a big ol grump, especially if someone ruins her beauty sleep. Don't you worry about her none.” Pinkie Pie replied, wrapping one hoof around her sister’s shoulder and giving her a gentle squeeze.

“Don't worry dear, you can sleep with us tonight.” Cloudy Quartz replied while patting the bed. “There is plenty of room and more than enough for all three of us. Oh and Pinkie, would you mind grabbing the cot?”

“But I thought you said we could sleep together?” Marble whispered sadly.

“Oh I do, that's just our cover.” Cloudy whispered, flashing her daughter a wink.

“Here we go!” Pinkie declared as she yanked the cot out from the closet and set it up in a single swift motion before jumping back on the bed. “So, you wanna do it now?”

Marble gulped, leaning back as Pinkie leaned forwards, the pink pony’s eyebrow wiggling ridiculously. “Well I was really turned on already.” She whispered. “Plus if we start doing it more often you won't be so pent up when Maud and mom go to the university next week… Okay Pinkie, I’m ready.”

“Yay!” Pinkie exclaimed happily before leaping onto her sister and pinning her down. “On a scale of one to ten, how hard do you want it?”

Marble looked away from the manic grin on her sister’s face while blushing nervously. “Umm, how about a four to start? It's been a little while since I’ve done it.”

“Oh I wouldn't worry about that dear.” Cloudy Quartz remarked slyly. “Pinkie has a way of opening you up, no matter how tight you are.”

“Yupper doodle!” Pinkie Pie declared.

“Well then maybe a six?” Marble replied, looking up at her sister expectantly. “I do miss how fast you are. Limestone is good, and big, but she doesn't have your same…” Marble trailed off, struggling to come up with the right word.

“Energy.” Cloudy Quartz finished, prompting Marble to nod.

Pinkie Pie grinned, her hard cock which was resting on Marble’s stomach twitched excitedly. “Oh I just know you’ll love every second of it.”

Marble could only watch with nervous excitement as her sister pulled back her hips and dragged the thick head of her cock down Marble’s stomach. Leaving a thin trail of pre, and what Marble quickly realized was her mother’s juices in her fur, matting it slightly. Between that, and the hungry, almost predatory look on Pinkie Pie’s face Marble nearly reconsidered her words, before suddenly becoming oddly turned on by the entire interaction. Pinkie was passionate, and loved with an intensity few could rival, and at this moment, on the precipice of receiving that love, Marble was incredibly excited.

It wasn't much further until the head of Pinkie Pie’s cock had slid all the way down from Marble’s belly button and rested at the entrance to her pussy. The thick appendage was so wide, so fat that the shy pony could feel every twitch and pulse as it rested against her body. Gulping down her worry, Marble looked up at Pinkie Pie and nodded. “I’m ready, take me.”

“Now Pinkie, try not to make her cum too hard.” Cloudy Quartz cautioned. “Marble’s voice travels quite far.”

“I promise that when I make her cum nopony but us will hear it.” Pinkie Pie vowed before looking down at her sister. “Let's have some fun, shall we?”

Chapter 5

“I promise that when I make her cum nopony but us will hear it.” Pinkie Pie vowed before looking down at her sister. “Let's have some fun, shall we?”

“Yes please!” Marble declared with a small grin.

Pinkie Pie smiled right back as she shifted into a slightly better position. Their hips aligned, and their bodies ready, Pinkie Pie wasted no more time, and thrust forward. Both ponies moaned in pleasure, though they had the presence of mind to stifle their cries, lest the other members of their family hear them. Before Pinkie Pie thrust forward again she shifted her hooves a little closer to Marble’s body, allowing her the leverage she needed.

This time her thrust wasn't just powerful, but was also deep, not stopping after only a few inches and plunging over half of Pinkie’s cock inside her sister. This time Marble couldn't stifle her cries of pleasure, leaving Pinkie Pie in an awkward position, until an idea occurred to the mare. Thinking quickly, the pink pony leaned forward, and planted her lips against her sister’s and drowning out the other mare’s cries.

After Marble’s tight pussy began to loosen up somewhat, and the other pony relaxed slightly, Pinkie Pie pulled back. “It really has been a while, hasn't it Marble?” Pinkie Pie questioned.

Marble nodded weakly. “S-sorry about that. Your just so big.”

Cloudy Quartz snickered to herself. “I told you she’s a big girl.”

“I know but….” Marble shook her head. “You are way bigger than Limestone.”

Pinkie Pie grinned a little wider. “Oh, how I wish I could rub her face in that fact.”

Marble shot her sister a quick glare. “Don't you dare tell her I said that.”

The party pony made a zipping motion over her lips, before miming throwing away a key. “Good.” Marble declared. “You know how competitive she gets about certain things.”

Pinkie Pie nodded. “Ready for more?”

“Absolutely.”

Pinkie Pie thrust forward again, this time not quite as hard, careful to not have a repeat of last time. Thankfully Marble seemed to be prepared, and hardly made a sound as even more of her sister’s throbbing cock slid inside her. It felt oddly good in a way, relaxing, like a part of Marble’s being was complete, now that she had her sister’s cock wedged in her cunt. That feeling of relaxation spread throughout her body, and it wasn't long before Pinkie Pie was able to thrust forward a couple more times and bottom out in the mare.

Balls now resting against her sister’s ass, Pinkie Pie stopped to readjust once again. The pony body wasn't exactly designed with missionary in mind, but Pinkie Pie was nothing if not flexible, and she was determined to make this work. Besides, some part of the party pony really, really wanted to see her sister’s face as the mare’s womb was filled with spunk.

“Now do you doubt me?” Cloudy Quartz asked, giving Marble’s shoulder a poke.

The younger mare shook her head. “You were right, she really does help you relax.”

Pinkie Pie smirked. “It's a talent of mine. Now then, let's have some real fun!”

Before Marble had a chance to ask what real fun entailed, she felt Pinkie Pie pull back, and slam back inside. The actual action itself was immensely pleasurable, as it felt good to have her body spread wide by Pinkie’s fat dick. That wasn't the only part she enjoyed though, as it was also really good just to feel the pink pony’s body press against hers. Like all earth ponies of the Pie clan, Pinkie Pie was dense, and well muscled despite her seemingly poor nutrition.

To have the warm, oddly fluffy, yet also surprisingly powerful body of her sister press against her each time she felt Pinkie Pie’s cock bottom out inside her was something Marble found herself craving. That alone was enough to turn this already quite arousing situation into a strangely intimate one as well. Reaching out with her legs, Marble wrapped herself around Pinkie, ensuring the party pony couldn't pull out more than a few inches.

Something Pinkie Pie herself didn't seem to mind one bit, the pony grinning as she felt the soft limbs of her sister wrap about her. Emboldened by the increased intimacy, Pinkie Pie slammed herself forward repeatedly, her balls slapping against Marble’s butt. The sound of Marble’s half stifled moans, and Pinkie Pie’s grunts soon filled the room, and Cloudy Quartz found that she couldn't help but join.

Her hoof moved on its own accord, sliding between her legs and rubbing the aching, cum covered lips of her pussy. She hardly cared that it wasn't exactly the most sanitary of actions, as her fluids now intermingled freely with all the cum Pinkie Pie had pumped into her. All she cared about was how weirdly hot it was to watch two of her daughters couple with an almost violent intensity mere inches away from her.

Pinkie Pie had turned up the speed considerably after only a few short minutes, as Marble’s body quickly stretched and adapted to the pink pony’s girth and length. This increased relaxation, and adaptation allowed the excitable pony to move faster, as she didn't have to worry about hurting her companion as much. Something Marble found herself enjoying considerably, as it was quite a departure from the normally slow, and ponderous pace Limestone seemed to enjoy.

“Stars above that feels good, don't stop.” Marble whispered.

“Well I gotta stop eventually. I don't want to knock you up after all.” Pinkie commented, only to purse her lips. “I mean I do, but you probably don't want to be filled with our foals.”

Marble felt her cheeks burn bright with shame, and for a moment she imagined what she would look like with a belly full of Pinkie Pie’s kids. “R-right well you don't have to worry about that. Its a safe day for me.” Marble whispered.

“Great! Because I cannot wait to fill your womb with all the spunky spunk I can shoot!” Pinkie Pie declared with a grin.

“I’m getting close, just don't slow down.” Marble cautioned.

“You got it el capitan!” Pinkie Pie replied while giving the mare a quick salute.

And that was precisely what Pinkie Pie didn't do, her pace remaining as quick, deep and as powerful as ever. Each short thrust made the bed rock slightly, though thankfully not enough to hit the wall, in addition to making Marble moan again and again. Marble had not felt so full in years, and something told her that was all going to change when Pinkie Pie came inside her. In a way she was even looking forward to it, as one look at her still glowing mother, and her bulging belly told Marble that it was a completely pleasurable experience.

Getting closer by the second, Marble continued to hold tight to her sister’s body, while chewing on her lip, lest the sound of her pleasure become too loud. Though only a few minutes had passed since they began, it felt like Pinkie Pie was close as well, as the party pony’s cock throbbed needfully on occasion. Marble could feel every twitch, and throb of Pinkie’s cock, in addition to feeling her sister’s balls churn with seed.

Pinkie Pie was undeniably potent, and productive, two things that made Marble’s nethers tingle in anticipation. She didn't have to wait long though, for as soon as she felt her own orgasm coming, and began to hold Pinkie that much tighter. She could even feel her sister’s cock flare fully and stretch her in a way she had never felt before. It was like her very cervix was being forced open, and made ready to accept Pinkie’s seed, a feeling that made her cum harder then ever before.

She couldn't seem to utter any words to warn her partner of this change, and merely laid there, her hooves gripping Pinkie tighter than ever. Something Pinkie Pie didn't seem to mind either, as the pony merely thrust forward one last time, and buried every last throbbing inch inside her younger sister. Their lips met just as Marble’s scream of pleasure reached her lips, muffling it to the point that no one could hear it save for the two lover’s themselves.

As Marble’s body twitched and shook, her pussy spasming randomly, she felt her sister also begin to cum. Her orgasm was far more powerful than even Marble’s as a blast of seed erupted into the deepest reaches of her body. Followed closely by more and more cum that bloated her womb to the point that it felt warped, stretched in a way that she couldn't explain. The situation should have been painful, but there was nothing but pleasure the likes of which washed away any discomfort she may feel.

Marble was dimly aware of the fact that she was also making out with Pinkie Pie, but it seemed almost secondary to what was happening between her legs. Her belly stretched, and grew as it was forced to contain more cum then what should be possible. Then, finally, after Pinkie Pie had seemingly emptied her balls into Marble, she stopped, and pulled away. Their lips parted, though their bodies didn't, with the party pony only pulling back enough so they could look one another in the eye comfortably.

“That was amazing Pinkie Pie.” Marble muttered.

“Yeah, not bad for a first round if I do say so myself.” Pinkie Pie declared with a smile.

“Wait, first round?” Marble turned to her mother, who was chuckling to herself. “I thought you two already did it like a bunch of times.”

“Oh we did, but Pinkie Pie is something of a machine.” Cloudy Quartz replied. “Why I bet she could go for another six or so times. What do you say Pinkie Pie?”

The pink pony nodded confidently. “Oh yeah, I could probably give another six or seven loads too.”

“I um…” Marble blinked. “Wow.”

“So, are you ready for round two or what?” Pinkie Pie pressed.

“Round two?” Marble smirked. “I’m ready for round two through ten!”

Pinkie Pie gasped. “No way! You are so on.”

Cloudy Quartz chuckled at her youngest’s sudden enthusiasm. “Well as much as I don't mind watching you two have a little fun, you shouldn't forget about your dear old mother.”

“Don't worry mom, I’m sure Pinkie Pie can switch at round five or so. Right Pinkie?” Marble replied.

The party pony nodded. “You betcha mom! I got more than enough cum to pack you two the brim and then some!”

“Well alright, I’m ready when you are.” Marble declared.

“Awesome, because I can't wait another second.” Pinkie Pie exclaimed.

“Me neither.” Agreed Marble.

“That was amazing.” Marble muttered, limbs splayed in just about every direction.

“I must agree.” Added Cloudy Quartz.

“I think I’ve finally been spent.” Murmured Pinkie Pie, who laid between both ponies, her soft cock resting against her stomach.

The three mares laid close to one another despite the heat that radiated from their bodies. Pinkie Pie’s forehooves gripped a forehoof from each of her partner’s holding the limbs tightly. The pink pony was covered in sweat, which dripped from head to tail, matting her fur completely, and making her appear quite disheveled. Despite that, she wore the biggest smile of the group, a smile that remained even as she lay there, eyes closed.

To her right, Cloudy Quartz lay in a similarly blissful state, one forehoof gripping her daughter’s hoof while the other rested on her stomach, rubbing her bloated belly in slow circles. The sheer amount of seed packed into her was enormous, and she had no doubt a passing observer would believe she was pregnant. Most eye catching of all was the fact that her pussy and ass both gaped slightly, unable to fully close, as cum oozed out of both holes. It wasn't a lot, as most of the pink pony’s seed was packed tight in her womb, but it was still enough to leave a puddle between her legs.

A feature she shared with her youngest daughter, who was in a similar situation as the elder mare. Her own belly was bloated just as much, her cunt and ass similarly hanging open, her fur also completely matted while the taste of cum stuck to the inside of her mouth. She too had the same wide, blissful expression as both her mother and sister, though she seemed more ready to sleep then either of her bed mates.

That was until a sudden knock on the door made nearly jump out of bed, and only stopped from doing so by Pinkie Pie who still held her hoof. “Is Marble in there?” The slightly gruff voice of Limestone asked from the other side of the door.

Cloudy Quartz rose into a sitting position, placing a hoof to her lips in order to shush her daughters and allow her to speak. “Yes, I’m afraid she had a bad dream. Pinkie and I are comforting her.” Replied the elder pony in a calm, patient tone.

“Oh okay, do you need the cot?” Limestone asked.

“We already have it.” Cloudy answered.

“Oh alright then.” Limestone muttered, as if half to herself. “I was just worried about her is all.”

“I’m better now, thank you Limestone.” Marble added.

The three ponies could hear a small, almost imperceptible sigh of relief from the other side of the door. “That's good, well I won't keep you any longer. Sweet dreams.”

Pinkie Pie giggled to herself as she heard Limestone’s hoofsteps trail into the distance. “Sweet dreams? She never says that.”

“She always says that to me.” Marble replied, a slight blush crossing her face. “Ever since she heard about my night terrors.”

“She's such a sweetheart.” Cloudy added.

“Yeah, her and Maud always check on me.” Limestone murmured slightly dreamily. “Its almost hard to believe they have as much sex as they do.”

“Wait what?”

Chapter 7

Time passed as it always did on the farm, slowly, with each minute taking a short eternity to tick by. Pinkie Pie settled into farm life relatively easily, though that was only possible due to the fact that she was regularly fucking both her mother and one of her sisters. This secret wasn't too hard to keep at first, as Limestone and Maud had their own nightly activities they wished to hide from their family.

It didn't stay that way for long though, as Pinkie Pie’s desires grew ever more insatiable, no matter how many times she indulged them. Then things really began to change when Maud and Cloudy Quartz left for their trip with a large wagon full of what they had managed to mine or cultivate. Selling their harvest was only the beginning though, as Maud was intent on checking out the local university and Cloudy Quartz wanted to take a detour as well but was cagey about the details.

Which meant there would be over a week where Limestone wouldn't have Maud, and Pinkie Pie wouldn't have Cloudy Quartz. Instead, the two futa mares had Marble as the only one capable of satiating both of their more base needs. Which meant the youngest Pie was left to content with a pair of well endowed siblings desperate to rut her at every opportunity.

It was a strange situation to say the least, as Limestone didn't know about the relationship Marble and Pinkie Pie had. Though Pinkie Pie and Marble knew of Limestone’s less than hidden desires for Marble’s generous posterior. Even if it was a strange situation, they made it all work, with Marble bouncing between her sisters, sucking and fucking them nearly constantly.

Things wouldn't remain that way forever though, and it wasn't long before things began to get a little more complicated.

Pinkie Pie grunted as her and her sister’s hips rested firmly against each other. The futa mare’s cock was buried in the other girl’s pussy and the party pony herself was in complete bliss. Sure she may have been laying on her back on the rocky earth, somewhere in the east field with only a foot of cover obscuring her from passerbies but that didn't really matter to Pinkie Pie though, as she had everything she wanted right there.

Marble shuddered as she slowly adapted to her sister’s mammoth length, and the way it twitched needfully inside of her. It hadn't been long since she had sucked Pinkie Pie off, so the young mare could still feel a heavy load of marecum sitting in her belly. Even still, Pinkie Pie was as hungry as ever, and had somehow convinced Marble to have sex in the middle of the field in broad day light.

Marble was just glad she had at least managed to find a long boulder to provide at least a little bit of protection.

“Thanks Marble.” Pinkie Pie whispered. “I really missed fucking you in the shower this morning.”

“S-sorry Pinkie Pie, but Limestone has started fucking me after she wakes up as well and enjoys using my pussy as a cock sleeve while she sleeps.” Marble whispered back, blushing profusely.

“Oh we have got to try that sometime soon.” Pinkie Pie declared.

Marble blushed even deeper. “Maybe tonight Pinkie Pie, but let's hurry before Lime-”

“Hey Marble, is that you back there?” Shouted a familiar voice.

Marble ducked beneath the long slim rock, and held a hoof against her sister’s lips while at the same time accidentally clenching down around the invader resting against the entrance to her womb. Marble’s tight grip combined with the position they were in meant that Pinkie Pie felt as though she was having her dick milked. It also made it very difficult to stay quiet, as the party pony wanted nothing more then to fuck her sister’s brains out.

“I saw you back here. Come on out! I just want to have a little fun.” Limestone barked, her hooves stopping a few feet away from the prone dou laying just out of sight. “Like ya know, as a break. I figured you deserved it given all the uh, great work you’ve been putting in.”

Pinkie Pie’s eyes rolled into the back of her head, and her cock twitched, alerting Marble to the fact that her sister was mere moments from orgasming. Marble, knowing full well that she wouldn't be able to keep herself from crying out should that happen desperately hoped Limestone would leave them alone.

And soon.

“Well if you are around here just come back to the house soon, thanks.” Limestone shouted before turning and trotting away.

Pinkie Pie came immediately, filling her sister to the point of bursting, and the two mares lay there panting for breath.

“That was weird.” Pinkie Pie exclaimed after the post orgasm bliss had finally began to dissipate.

“Yeah, Limestone is really starting to miss Maud.” Remarked Marble.

“I’m sure it will be fine. We only have a few more days left before mom and Maud are back.” Pinkie Pie pointed out.

“I hope your right Pinkie Pie.”

After that, things got predictably worse, with Marble getting passed between her sisters nearly constantly. Both of her well endowed siblings used the poor mare like their own personal cum dumps, fucking her several times a day without rest. Not like Marble was against this of course, she rather enjoyed the attention, but that didn't mean it didn't cause problems for the three mares.

Marble sat on the toilet, doing her best to push out the multiple loads Pinkie Pie had just fucked into her. With a grunt, she managed to push the last of the thick seed from inside of her, and sighed contentedly as she flushed it down the drain. She hardly even had a second to herself before the door opened and a flushed Limestone Pie stood in the doorway.

“I need you, now.” Stated the gruff mare, who kicked shut the door behind her.

Marble gulped. “R-right here?” She asked nervously.

“Yes, right here, right now, mouth or pussy, I don't care.” Limestone demanded.

“Well uh…” Marble paused, quickly realizing that her cunt was probably still stretched from the hours of abuse that Pinkie Pie had put it through over the course of the evening. “Mouth, I um, like how you taste.”

“Good, head down please.” Limestone half asked, half commanded.

Marble obeyed, lowering herself down and turning her head to the side. Limestone wasted no time trotting forward, and placing her cock against her sister’s lips. Once that was done, and Marble had begun taking the mare’s dick into her mouth, Limestone bucked her hips forward, shoving herself deep. The position was a little awkward, what with Marble half kneeling under her still standing sister, but they made it work.

“Sorry Marble. I need this.” Limestone apologized before using one hoof to hold Marble down while she throat fucked the shy mare.

Who could do little but take it, moaning around the massive invade inside of her throat and hoping her sister took her time.

Days went by much like that, with Pinkie and Marble’s antics only remaining undiscovered by Limestone because of just how horny the other mare was. Thankfully for Pinkie Pie, Limestone’s mind was clouded with lust and the usually sharp, observant pony was a little easier to fool. Even still, Marble couldn't help but think it was only a matter of time until they were discovered and on the last day before Cloudy Quarts and Maud’s return, it happened.

Marble stood on her mother’s bed, with her sister’s huge pink dick pounding into her pussy like a jackhammer. The results of three other orgasms already rested inside of the girl, either in her stomach, or her womb. Either way, the bulge Pinkie Pie’s cum made was large enough to slosh audibly, and be easily noticeable if anyone walked in.

Pinkie Pie was close to adding a fourth load, and was surprisingly quiet, having spent all her best compliments and teasing already and was content to enjoy the act itself without uttering a word. Marble didn't care either way, or at least that's what she told herself, as she rather enjoyed the gentle, and naughty teasing Pinkie Pie was known for. She didn't think of that right now though, all that existed was Pinkie Pie’s hot breath on her neck, and the distinct click of the mattress hitting the wall whenever the party pony thrusted.

“I’m close.” Pinkie Pie whispered.

“Give it to me.” Marble whispered back.

And then they both came, with Marble’s body somehow bloating even more than before. Pinkie Pie draped herself over her sister’s back, panting hard as her cock twitched and shot rope after rope into her sister’s body. They would have stayed this way for several more minutes, had the sound of hooves not come from the entrance to the room.

“Marble are you in there? You didn't get started without me did you?” Limestone called.

“Pinkie Pie, you locked the door right?” Marble asked.

Pinkie Pie shrugged. “I think so.”

The door clicked open, Marble shot Pinkie Pie a glare, and the pink pony laughed nervously.

“What is… oh. My. god.” Limestone muttered, her jaw hanging open as she stared at the two ponies. “I can't believe you two! On mother’s bed no less!”

“It's not what it looks like?” Pinkie Pie offered weakly the pony having started pulling out of Marble only to stop half way.

Limestone sighed and planted a hoof against her forehead. “I can't believe you two.”

“I’m sorry Marble.” Limestone murmured, hanging her head in shame.

The older mare snorted. “I don't care what you do with your body, but without a condom? Come on. Your both smarter than that.”

“Bwuh?” Pinkie Pie murmured.

Limestone rolled her eyes, trotted forward, and gently pushed Pinkie Pie off Marble, causing the pink pony to land on her butt at the edge of the bed. “Augh, and she finished inside of you as well.” Limestone muttered in disgust. “I know it's not quite heat season but it's coming up, and you can't be too careful.”

“Well I uh, really like how it feels?” Marble offered weakly, the pony sitting down at the edge of the bed only to slip and fall to the floor, landing on her butt. “Oof.”

“Oh come on, it's no big deal Limey.” Pinkie Pie retorted, the mare quickly hopping off the bed and trotting over to Marble, inadvertently revealing her cum covered cock to her younger sister.

“What would mother say if you knocked up your own sister huh?” Limestone retorted, jabbing Pinkie Pie in the chest. “You can't keep jumping into everything without thinking.”

Marble glanced over to Limestone, only to realize that she too was as hard as a rock, and that her cock was mere inches away. Due to the two mares arguing directly in front of her, Marble was bathed in the heavy scent of two aroused futa mares. While also getting a good view of their massive, throbbing erections that were within easy reaching distance.

“When I fuck mom I don't wear a rubber either and shes totally fine with it.” Pinkie Pie retorted, her now hard cock bumping against Marble’s left cheek.

“I can't believe you would do that! She is in a vulnerable place right now and you are taking advantage of her!” Limestone shouted, her cock brushing against Marble’s right cheek.

“I am not! Mom fantasized about me when she was still married to dad so there.” Pinkie Pie stuck her tongue out at her sister, which only made the other mare even more irate.

Marble however, had enough and reached out, grabbing both of the mare’s cocks in her hooves.

“What the-

“Hey, watch it!”

“I need you two to start using your heads, and not the ones in my hooves. Got it?” Marble declared.

Pinkie Pie gulped and nodded.

Limestone winced. “Alright, fine.”

Marble lessened her grip slightly, but didn't let go. “Now apologize to one another.”

“But I-”

“But she-”

“But nothing, do it right now.” Marble countered.

The two older ponies shared a sigh.

“I’m sorry Limestone.” Pinkie Pie murmured.

“I’m… sorry too Pinkie Pie.” Limestone whispered.

“Good.” Marble released her hold entirely. “Now I’m gonna need you two to fuck me like, right now please.”

“Don't you think-” Limestone began.

“Shotgun vagina!” Pinkie Pie shouted.

Limestone cursed under her breath. “Fine, I’ll take anal. I don't want your sloppy seconds anyway.”

“More like sloppy fourths.” Countered Pinkie Pie.

Limestone groaned even louder. “I’m already regretting this.”

Chapter 8

“I can't believe you made me wear this stupid thing.” Grumbled Pinkie Pie as she fidgeted in place, trying to get the condom to feel less restricting and failing utterly.

“And I can't believe you needed me to guilt you into doing so.” Retorted Limestone.

“But I already came inside of her like a whole bunch of times.” Whined Pinkie Pie.

“I don't care how many times you’ve cum inside of her, if your in her pussy, your wrapping your tool.” Declared Limestone.

“I actually kind of agree with Limestone.” Murmured Limestone before she stood overtop of Pinkie Pie, the massive bulge in her stomach now reduced to little more than a slight bump.

“Daw come on, Marble.” Complained Pinkie Pie. “You know you love it.”

“I do enjoy the feeling but it's better to be safe.” Limestone remarked.

Pinkie Pie pouted. “Fiiine.”

Limestone took position behind Marble as the other girl kneeled down and took Pinkie Pie’s cock in her hoof, guiding it towards her cunt. After slipping the enormous dick into her tight pussy, Marble slowly sunk deeper on the other mare’s shaft. Until at last, their hips rested against each other, and Pinkie Pie was balls deep inside her sister once again.

“Mmmm much better.” Murmured Pinkie Pie as she gripped the other mare’s flanks.

“Don't get too carried away.” Warned Limestone, who was busy squeezing a heavy dollop of lubricant onto the tip of her cock.

“Well hurry up already, I want to fuck this cute pony already.” Pinkie Pie exclaimed, before planting a kiss on Marble’s lips.

Marble blushed and kissed her sister back. “And I want you to fuck me too, you sexy studs you.” Marble replied.

“That's actually kinda hot.” Murmured Limestone.

“What did you say Limey?” Asked Pinkie Pie.

“Nothing.” Exclaimed Limestone before she thrust forward, ramming the wide, flat head of her dick against Marble’s unyielding hole.

“Oof be gentle- ooh that's good.” Marble murmured as she felt her asshole slowly get spread around her sister’s girthy cock.

“Stars above you are tight.” Grunted Limestone as she bucked her hips forward, driving herself deep into her sister's stretched asshole.

It took a lot more grunting, thrusting, and pushing but it wasn't long until Limestone was as deep as she was going to get into her sister’s ass. With two well endowed futa mares now buried in her holes, Marble was on cloud nine and could barely stay standing. Thankfully she didn't need to, as both Pinkie Pie and Limestone took hold of her before beginning to thrust into her ass and pussy at the same time.

Marble’s forelegs quaked, strength quickly leaving them as she was overcome with pleasure. Her sisters both pulled out before pushing back inside at the same time, causing Marble’s stomach to bulge slightly and small indents of their cocks could be seen through her belly. She also felt incredibly full, the two hulking appendages filling her insides to the point that the mare felt like her body was utterly dominated by the huge dicks.

Pinkie Pie moaned, and Limestone grunted, the two mares thrusting hard into the smaller pony repeatedly. It didn't take long for the three of them to quickly fall into a routine, with Pinkie Pie thrusting forward just as Limestone was pulling back. The slightly older, more serious pie sister moved relatively quickly after Marble had gotten used to her girth. Then it was off to the races, with Marble’s holes having loosened enough to allow both sisters free reign to go at their own pace.

“Mmm your pussy is so nice Marble.” Pinkie Pie whispered.

The lust addled younger sibling couldn't even utter a response, the pleasure of getting double teamed rendering speech temporarily impossible. Instead Marrble merely moaned and nodded, her mind more focused on merely not falling onto Pinkie Pie by accident. Which wasn't difficult Marble felt like as her body was being held up more by her sister’s dicks then by her own strength.

Limestone grunted, her hooves digging into the plush bosom of her younger sibling. She used this leverage to pound hard and deep, ensuring she stretched as much of Marble’s ass as possible. Something she was doing a commendable job at, considering Marble felt like Limestone was stretching and filling every last inch of her ass.

Pinkie Pie suddenly decided that it would be a good time to pick up the pace, and she gripped Marble’s flanks tight in her hooves before pounding away. This sudden increase in speed took Limestone by surprise, and she quickly moved to match it, before going even faster still. The wet slap of her balls impacting the edge of Marble’s pussy grew almost as loud as the poor mare’s moaning was.

“Oooh that's good. I can feel you thrusting inside of her.” Pinkie Pie remarked with a giggle.

Marble blushed even harder, the young mare very aware that there was very little between her two sister’s dicks. Limestone stiffened slightly at the comment, her hooves shifting slightly further up so she could better squeeze Marble’s plump rump. With a slightly better hold, Limestone really pushed herself to go as fast as possible, racing Pinkie Pie, even though the party pony wasn't participating.

“Ooooh that's so good.” Marble muttered, the mare now unable to even move as she lay draped over Pinkie Pie’s chest, relying entirely on her sister’s hooves and cocks to keep her from falling completely.

It felt like she was being used like a sex doll by her two older siblings, and Marble was loving every second of it. Pinkie Pie was as well, though Limestone felt an old rivalry begin to make a comeback after years of not being an issue. Try as she might to ignore it, Limestone couldn't help herself, and she just hoped it wasn't too obvious.

“I’m getting close.” Pinkie Pie exclaimed.

“Me too.” Marble murmured between moans.

Smirking to herself, Limestone decided to hold out longer than her siblings, thus proving that she was better somehow. It wasn't the best plan, but Limestone found herself strangely dedicated to it, and the pony grew pretty confident when she felt Pinkie Pie begin to slow down. Marble also clenched down a little harder around the twin shafts buried inside of her, and a few seconds later the two mares came.

Pinkie Pie grabbed Marble, and began to make out with the other girl while filling the condom that she wore. In response, Limestone grunted, squeezed Marble’s hips and pounded the poor mare with every ounce of strength she had. Over and over she jackhammered her sibling’s ass until Marble was forced to abandon the kiss and lay there moaning uncontrollably, tongue hanging out of her mouth.

Then, just when Marble was coming down from her orgasm, Limestone rammed herself as deep as possible into Marble’s back door. With balls now draped over Pinkie Pie’s cock, Limestone came hard, unloading what felt like every last drop she had into Marble’s back door. The younger pony’s moans grew slightly higher in pitch, and she shuddered as Limestone’s cum gushed into her.

When finally it felt like she had given all she could, Limestone let out a deep, shuddering sigh of relief. “That was pretty good Marble.” Limestone remarked.

“T-thanks.” Marble stuttered.

“Totally, are you ready for round two?” Pinkie Pie inquired.

Limestone blinked. “Round two already?”

“Heck yeah. You aren't satisfied with just one round right?” Pinkie Pie inquired.

Limestone stiffened. “No of course not.”

“It doesn't sound like your up for it.” Pinkie Pie exclaimed.

“I am and I’ll prove it to you!” Limestone retorted.

“Ooh wow you just got really hard.” Marble murmured before getting her asshole plowed by Limestone Pie.

“Alright, lets get this party started!” Pinkie Pie shouted.

Pinkie Pie leaned against the wall and wiped her forehead with a hoof. “Whoowee that was sure something.” She exclaimed.

Limestone grunted, the gruff pony trying to hide the fact that she was almost completely exhausted. “I suppose it was.” Muttered the mare.

“Do you think Marble is okay?” Pinkie Pie asked.

Limestone shrugged and glanced back into the room the two ponies had just left and to where Marble now lay. The younger pony was sprawled out on her back, several very full condoms that had been tied off and now resembled water baloons were scattered around her. Cum dribbled out of the edges of her mouth, as well as from her stretched asshole and well used cunt.

“I’m sure she's fine.” Limestone assured.

“I don't know, we went at her pretty hard there for a bit.” Pinkie Pie murmured.

Limestone shrugged. “Shes a pie. She's tougher than she looks.”

Pinkie Pie nodded. “I suppose that's fair.”

The door to the house opening suddenly made both parties turn to where their mother and sister now stood. Cloudy Quartz and Maud were both a little road weary, with a fine layer of dust covering their coats, and clothes. They also seemed a little anxious but other than that werent too worse for wear overall.

They quickly deposited the single peice of luggage they had brought with them before stepping fully into the house.

“Mom your home!” Pinkie Pie shouted in glee, scooping her mother up in a tight hug and spinning her around.

Cloudy Quartz blushed and kept one hoof on her stomach while the other patted Pinkie Pie on the back. “Hello to you too my wonderful daughter. I hope you three were able to get along well without us.” Cloudy Quartz remarked.

Pinkie Pie took a step back and grinned. “Yupper doodle. We may have gone a little hard on Marble near the end though.”

Muad raised an eyebrow, and glanced at Limestone curiously. “Oh really. Is this true sister dearest?”

Limestone coughed and nodded. “Me and Pinkie Pie came to an understanding.”

“That is good.” Stated Maud.

“So why are you guys so late?” Pinkie Pie inquired. “You were supposed to be home yesterday.”

“You didn't have any trouble at the market did you?” Asked Limestone.

Cloudy Quartz shook her head and blushed slightly. “We just had to confirm something important.”

“Like what?” Replied Pinkie Pie curiously.

“Mom’s pregnant.” Maud exclaimed.

“What?!” Shouted Limestone.

Cloudy raised a hoof placatangingly. “Relax. I am keeping the foals and we are all quite healthy.”

“But I thought you said you couldn't have kids anymore.” Pinkie Pie remarked only to gasp. “They arent mine are they?”

“They are yours, and I guess your just more virile then most stallions could ever hope of being because this field was barren until you planted your seed.” Cloudy Quartz announced.

Pinkie Pie fell onto her butt with a dull thud. “Wow this is crazy. I never thought this would have happened in like, a million bajillion years.”

“Also I’m in heat.” Maud claimed, staring intently at Limestone.

“Oh uh, that's great?” Limestone replied nervously.

“Which means that Marble is likely to go into heat soon as well.” Added Cloudy Quartz.

Pinkie Pie gasped, and disappeared back into the other room, emerging a second later with a bleary eyed Marble held in her hooves. “Did you hear that Marble?” Pinkie Pie asked.

“Bwuh? Oh hi mom, Maud.” Marble greeted, while blinking the haziness from her vision.

“You’ll be going into heat shortly, Maud already is, and I’m pregnant with Pinkie Pie’s foals.” Cloudy Quartz quickly summarized.

Marble blinked, looked at each of her sisters and then promptly sat on the ground. “That's a lot to take in.”

“Speaking of taking in.” Maud turned to Limestone. “I want your foal.”

Pinkie Pie gasped. “Wait how many babies did I put in you anyway?”

Limestone blushed, and rubbed the back of her neck awkwardly. “Well I mean, I guess it's not that big a deal anymore considering who impregnated mom.”

“So?” Maud pressed with a hint of hesitation.

Limestone sighed. “I suppose if we can afford to then I don't see why not.”

“I am overjoyed.” Maud stated, the smallest hint of a smile crossing her face.

“Marble! I gotta knock you up next too!” Pinkie Pie declared.

“Well I mean I always did think it would be nice to have foals of my own sometime…” Marble murmured under her breath, a hoof rubbing her belly absently.

“And I have more good news.” Cloudy Quartz stated, stepping forward into the center of the room. “Those crystals we thought werent worth anything were in fact worth quite a lot.”
“How much are we talking about exactly?” Limestone inquired.

“We’re rich.” Stated Maud, who opened the peice of luggage, prompting bits to spill all over the floor.

“Wowee, so we totally could afford to put a baby or three in you Marble. Isn't that great?” Exclaimed Pinkie Pie, who squeezed Marble’s shoulder, and made her blush even harder.

“I suppose-” Marble began only to get cut off by Limestone.

“Wait, who said you were going to be the one to knock her up? I want her to carry my foals too you know.” Limestone declared.

Maud blushed slightly. “This is so hot.”

“Now girls, Marble is young, she can carry both your foals in time.” Cloudy Quartz interrupted.

Marble’s face turned an incredibly deep shade of red. “M-m-multiple foals.”

“Why don't we play a game then?” Announced Pinkie Pie.

“What kind of game?” Limestone replied hesitantly.

“We use the condoms until shes for sure in heat, then we both fuck her at the same time, and whoever knocks her up is the winner.” Pinkie Pie declared.

“At the same… oh my.” Marble murmured before nearly fainting, and only being caught at the last second by her mother.

“If Marble is okay with it. I’ll accept your challenge.” Responded Limestone.

Marble hung her head and gulped. “I guess so.”

Chapter 9

“Thanks Marble, that was great.” Pinkie Pie exclaimed, as the futa mare retrieved her cock from her sister’s mouth, the head of which popped audibly after leaving Marble’s lips.

“N-no problem Pinkie.” Stuttered the mare, who lay on her belly in the center of the bed.

“Your ass is as fantastic as always.” Declared Limestone, who gave the younger pony’s butt a firm smack, before pulling her cock from Marble’s ass.

“T-thanks Limestone.” Whispered Marble.

“Whelp, I better get back to work.” Proclaimed Pinkie Pie who hopped off the bed and did a quick stretch.

Limestone followed her example, stretching as well after she too had gotten off the bed. “Sounds like a plan. Are you alright to clean up by yourself Marble?” Limestone asked.

Marble nodded meekly. “Yeah I got it.”

“Alright then, I’ll see you two for lunch in a bit.” Exclaimed Limestone before stepping out the door.

Pinkie Pie eyed Marble’s bulging, cum filled belly and stopped at the door. “Well maybe I could stay for just one more-eek!”

Pinkie Pie was pulled bodily out of the room by Limestone’s firm hoof. “Now Pinkie Pie, you know the deal. We have to get that next shipment ready for that buyer out of Canterlot.” Limestone reminded her.

“I know Limey, but we got like a week for that. Besides, we’re already loaded now!” Pinkie Pie exclaimed.

“That doesn't mean we can just start slacking off now.” Retorted Limestone.

“Yeah yeah. Your on the east field today, right?”

“And you're in the west.” Stated Limestone.

“Okie dokie loki.” Pinkie Pie jovially exclaimed before hopping down the hall and out the door, followed closely by Limestone.

The two girls went their separate ways, leaving Marble to waddle into the bathroom, expell the cum that filled her lower intestines and then trot back into her bedroom, ready to clean up her sheets. Only to stop after only taking a single step inside as she had noticed Pinkie Pie had already partially slipped back into the room, with the mare half in, half out the window.

“Shh, I need another round, don't tell Limestone.” Pinkie Pie whispered.

“Dammit.” Muttered a voice from the doorway, where an annoyed Limestone stood, a frown on her face.

Pinkie Pie chuckled nervously. “Great minds think alike?”

Limestone frowned. “I guess we could go one more round, but after that we really do have to get back to work.”

Marble blushed and got right back into the same position she had been in a minute earlier. “Well I’m ready when you girls are.” She exclaimed with a hint of excitement.

“Shotgun butt!” Shouted Pinkie Pie before she finished crawling in through the window.

“Fine with me, I was hoping to get my cock spit shined for Maud later anyway.” Limestone murmured, the pony getting into position just as Pinkie Pie did the same.

Limestone laid down on her side in front of Marble, presenting her hard cock and guiding it towards the younger mare’s mouth. While this was happening, Pinkie Pie was shifting into a better spot, as she had already leapt atop Marble’s behind. With her weight pressing firmly down on Marble’s back, Pinkie Pie angled her cock towards the younger girl’s asshole and pressed forward.

The result was Marble’s mouth and ass being penetrated at about the same time, something the younger mare had come to look forward to. Unfortunately for Marble, Limestone and Pinkie Pie’s one sided rivalry had continued unabated since yesterday, which meant that Marble was continually getting fucked by both of them. Pinkie Pie also had a knack for finding Marble and Limestone whenever they had snuck off together while Marble actively hunted down Pinkie Pie whenever she assumed the party pony and Marble were going at it again.

In the end, Marble couldn't really complain as she had come to truly enjoy all the attention she now received and though she never mentioned it out loud, this turn of events was rather nice. She felt wanted, needed, and attractive, even though both of her sisters were after her body, if they had time they would always stay and cuddle with her afterwards. Especially Pinkie Pie, who loved cuddling almost more than Marble herself did and Limestone enjoyed the quieter moments as well even if she tried not to show it.

Bobbing her head, Marble took Limestone’s cock deep in her mouth and into the entrance to her throat. While this was happening Pinkie Pie was plunging her cock deep into the younger mare’s asshole. The feeling of stretching wasn't intense as usual, but that was mainly due to the fact that Marble had just received a half hour long ass fucking only a few minutes ago.

Pinkie Pie certainly didn't mind, as the party pony groaned and continuously shoved herself deeper, not content until her balls rested against Marble’s dripping slit. At the same time, Marble had also reached the base of Limestone’s cock, as she knew the older pony would grow irritable if Pinkie Pie got ‘ahead of her’. Marble knew better than to argue with the pony when she got like that however, and merely sucked her cock dutifully.

The three ponies fell into the same rhythm they always did when they ended up like this, with Pinkie Pie pounding away and Marble doing her best to match that pace. As she bobbed her head, the youngest Pie sibling kept her tongue pressed firmly against the underside of Limestone’s cock. While at the same time making sure to devote one hoof to squeezing and kneading Limestone’s balls as she knew the older pony enjoyed.

“Fuck your good at this.” Limestone murmured.

“Speaking of good. How was this morning?” Pinkie Pie asked.

Limestone blinked. “What do you mean?”

“Breeding Maud silly. She said she was too tired from the trip last night, but knowing Maud she was probably raring to go bright and early. After all, she may be a one partner kind of pony, but she's as needy as any of our family.” Pinkie Pie replied, while her cock continued to piston in and out of Marble’s stretched asshole.

Limestone’s mouth hung open, and she thought back to this morning when she had ignored the look Maud had given her in order to use the washroom. Where she had found Marble blowing Pinkie Pie, and their mother, Cloudy Quartz doing her mane. After that the day had gotten a little messy, as Limestone ended up double teaming Marble in the bathroom, and then on the bed right after breakfast.

Leaving no time to devote to Maud, despite the looks that Limestone hadn't noticed until now that she thought back on it.

“Oh shit.” Limestone murmured.

Marble blinked in shock as she felt Limestone suddenly grab her head, pull her back, and then leap off the bed. Limestone’s hooves scrambled to find purchase on the clean oak floors, her eyes wide with barely contained terror.

“I’m coming Maud!” Cried the Limestone before disappearing around the corner.

Pinkie Pie giggled. “She really needs to pay attention more.”

Marble shook her head. “You two have so much in common.”

“What do you mean?” Pinkie Pie questioned.

“Nothing at all Pinkie, nothing at all.”

“I’m so sorry Maud, I totally forgot and… what's going on?” Limestone asked after coming to a skidding halt in what was now officially their room.

Maud tightened a knot around one of their bed posts firmly. “I’m merely getting prepared.” Stated the pony.

Limestone sniffed the air, and found that it had a rather pungent, needy scent to it, one she knew came from her sister. Maud had ditched her usual outfit whenever she was home, which meant that Limestone could see clearly the thick trail of liquid that dribbled from her sister’s pussy. Tearing her gaze from the very aroused mare before her, Limestone glanced over the four cords of rope which were attached to each of the bed posts.

Maud had used the same rope they usually did, though her knots seemed a little more elaborate then the last time Limestone had seen them.

“Wow, it's been awhile since you broke out the ropes.” Limestone pointed out.

“Lay down.” Maud commanded.

Limestone did as she was told, resting on her back in the center of the bed. “Look, I’m really sorry about getting caught up. I got distracted and well… I don't have any excuse for what I did.”

“I have been looking forward to having you knock me up since the day we started dating in secret.” Maud stated as she fastened one of the ropes around Limestone’s forehooves before moving down to the bottom of the bed.

“I know, and I should have been thinking about you before I thought about Marble.” Limestone continued.

Maud pulled tight another knot around Limestone’s hoof, and then moved onto the next. “Why must you always try to match Pinkie Pie in whatever she does? You know she doesn't have a single antagonistic bone in her body.”

“I know, but it's just, she's bigger than me, and despite everything I just feel inadequate. I’m the older sister, I should be better.” Limestone murmured.

Maud sighed, stopping as she was tightening the third rope. “Am I not enough for you?”

“What? No, I mean. You are everything I want. I may think of Marble sometimes but youre my bedrock gal, my first love.” Limestone pressed, smiling hopefully.

“I can accept your feelings for Marble, but you must abandon your little rivalry with Pinkie Pie.” Maud tightened the third rope the rest of the way and moved onto the last one. “You are just going to end up hurting yourself or Pinkie Pie, and I cannot allow either of those things to happen.”

Limestone sighed, and looked down. “I know. I’m sorry Maud. I’ll apologize to her later.”

“Good, because right now you are all mine.” Maud declared as she tightened the fourth, and final rope.

Limestone blinked and tugged at her hooves. “Oh wow, these ropes are pretty tight. I guess your not using those fancy slip knots again.”

“I am not.” Maud stated as she crawled atop the bed.

Limestone gulped, the barely contained desire in Maud’s eyes intimidating her slightly. “I won't be able to apologize to Pinkie Pie for a while, will I?”

“You will not.” Declared Maud.

Chapter 10

Limestone blinked and watched as Maud did not immediately begin to ride her like a two dollar hooker. Instead, the other mare leaned over, and opened the drawer of their nightstand, retrieving a scroll from inside. Which she placed against her belly before channeling a bit of magic through her hoof and causing the piece of paper to briefly glow a faint grey light.

Maud then discarded the now used magical item off the side of the bed and turned back to her lover. “Now then, where were we?”

“What was that all about?” Limestone inquired, gesturing with her nose towards the fallen scrap of paper. “You didn't say anything about magic.”

“I had to be sure, and this helps with that,” Maud stated evenly, roughly grabbing the other mare’s semi hard cock and guiding it towards her dripping entrance.

“How so? You’re not doing anything crazy are you?” Limestone pressed.

Maud paused, and shot her lover a frown. “I would never do something crazy. This merely ensures that I don't lose any of you. That is it.”

“Lose any of…” Limestone muttered, a grin spread across her face. “Oooh that's kinda hot to be honest.”

“I thought you would say that,” Maud exclaimed, leaving the head of the other mare’s cock resting against her pussy before placing her forehooves on either side of Limestone’s head. “Now then. Are you ready to knock me up?”

“I’ve never been more ready for anything in my entire life,” Limestone stated eagerly. “Go ahead babe.”

Maud’s lip trembled ever so slightly, the ghost of a smile briefly crossing her face. “As you wish,” she remarked simply before dropping her hips.

A second later and the throbbing tip of Limestone’s horse cock pierced deep into the other mare’s body. Aided by an incredibly generous amount of natural lubricant, it took mere heart beats before the futa mare was as deep as she was going to get. The second their hips connected, Muad let out a low, shuddering moan, her hooves resting on her lover’s shoulders as their eyes met.

“Stars and stones it's good to be back inside of you again,” Limestone exclaimed, a smile growing on her lips. “Though something tells me I wont be pulling out for quite some time.”

“Not until I know for certain that you’ve knocked me up,” Maud replied plainly. “Do you think you can handle that?”

“Well I did finish a few times today already and- yowch,” Limestone winced as her lover’s pussy clamped down around her cock like a vice. “Sorry, sorry. Was just teasing you a little. Of course I can handle it”

“Maybe I don't want to have sex anymore,” Maud offered.

“You and I both know that's a lie,” Limestone claimed, leaning forward as much as the ropes would allow. “I can almost feel how badly you want me to fill your womb with cum.”

“I do want it quite a bit. Though Pinkie Pie could accomplish the same result,” Maud murmured.

“You and I both know that's not going to happen,” Limestone remarked, grinning even wider. “Come on then, let's do this already.”

“You will be more cognizant of my needs from here on out, right?” Maud half asked, half stated.

Limestone nodded. “I promise.”

“Good,” Maud stated before leaning forward and planting a short, chaste kiss on the other mare’s lips. “Now, prepare yourself.”

Limestone didn't have any time to consider the threatening undertones in her lover’s words, because that same pony was already in motion. Her body rose quickly and fell just as suddenly, her hips slamming back down against Limestone’s crotch with a distinct clap which filled the small room. The sound sent a shiver up the futa mare’s back, a small part of her still worrying about waking up her other sisters or stars forbid, their parents.

Even knowing that wasn't a concern anymore wasn't enough to set Limestone’s mind completely at ease. Though, if she was being honest with herself, the chance of being caught had always excited her more than anything. The thrill of doing it in secret might be firmly in the past now, but the remanants of those many nights spent sneakily fucking in the dark had certainly left behind a lasting impression on both ponies.

Such that even now with there being absolutely no reason to stay quiet, Limestone could feel her sister unconsciously slowing her hips. As if trying to subtly contain the sounds of their love making, only to quickly remember that was no longer necessary. Then their bodies met with a more climactic slap of flesh on flesh, their moans slowly rising in volume as they began to relax.

In minutes the slow, ponderous pace that Maud had established at first was gone, replaced by one that bordered on frantic. The icey mare’s expression morphing from one of barely contained desire to that of outright lust. Though in Maud’s case that meant that her moans were only about twenty percent louder, and a faint smile was constantly present on her features.

Limestone however, was a little more open about how much she was enjoying the situation she found herself in. Sure a small part of her wasn't wholly convinced about the whole rope and bondage deal, but it was steadily growing on her. She didn't want to think of that right now, for all that mattered to her was the soft, velvety confines of her sister’s pussy which were wrapped tight around her thick futa cock.

“Fuck thats good,” Limestone muttered, the mare bucking her hips as much as she could.

Though she couldn't go far, Limestone always thrusted up into Maud’s dripping honey pot whenever the other female came back down. It took a bit of practice, but in the end Limestone figured out how to get a good hard thrust in fairly consistently. Though even still, she couldn't quite shake the strange pleasure, and slight irritation that came with being bound tight against the bed.

Maud seemed to relish this change however, with the mare becoming louder than usual, as well as a little more touchy the other times they made love. The laconic mare trailed her hoof down Limestone’s chest and caressed the other pony’s surprisingly soft features. Gazing into those slightly dull teal eyes, Limestone could see a barely contained desire, and a joy that Limestone had never seen before.

The slightly withdrawn, and usually reserved pony wanted, no, needed this. Limestone was almost a little taken aback by that small realization as such emotion was rare to see in the other pony. Yet, the longer she gazed within the blue orbs of her lover, the more Limestone couldn't help but feel empowered in a way.

Maud wanted her foals, to bear her children, and to make Limestone into a parent. It was an overwhelming feeling, but one that also made Limestone’s chest swell with pride. Immediately she put a little more strength into her thrusts, in addition to leaning forward and nipping at her lover’s neck whenever she had the chance. The effort paid off quickly, with Maud leaning forward and rewarding Limestone with a soft kiss on the lips.

Though it didn't last long, the embrace was a passionate one, and signified to both parties that they were ready to end round one. As usual, few words were spared by either pony, with both merely grunting, and moaning to let the other know how good they felt. A system which worked just fine as they knew one another so deeply that they didn't need to give one another anything more than a simple look to convey their deepest thoughts.

Maud adjusted her hips, settled her hooves on Limestone’s shoulders, and gave her butt a little wiggle before jumping right back into it. This time when she began to bounce it was clear she wasn't going to stop until she got what she wanted. Which was a womb full of cum.

Limestone could only hold on while she received the ride of her life, her excitable lover bouncing harder and faster with each passing second. Unlike nearly every other time they had fucked, there had been no slow insertion, nor gradual adaptation to Limestone’s girth. Which was fine as Maud’s love canal had been plumbed so frequently by her sister’s cock that it stretched quickly.

All of these factors and more built on top of one another, adding more pleasure to the already orgasmic experience. It couldn't last forever though, and only a few minutes after they began to fuck in earnest, Limestone could feel her orgasm begin to edge ever closer. She knew it wouldn't be long for her lover to hit the same high she was nearing either, as the girl’s pussy was starting to spasm every once and awhile.

The tight confines of Maud’s pussy squeezed down on her every few seconds, her intense desire to be filled nearly overwhelming the already frazzled mare. A brief feeling of tightness turned out to be the last straw, and all at once Limestone felt her orgasm arrive with all the force of a runaway freight train.

“I’m cumming!” Limestone shouted unexpectedly, her entire body suddenly becoming as stiff as a board.

Maud shuddered, the other mare clearly seconds away from experiencing the same bliss. “Give it to me,” she commanded.

Limestone did just that, unleashing an absolute torrent of incestious futa seed deep into her sister’s womb. The flared head of her cock held open the other mare’s cervix, forcing every last drop of cum into the pony and ensuring it could not escape. The second she felt the explosion of hot seed hit the deepest reaches of her body, Maud came as well.

The quiet mare’s hooves trembled, and she bit down on her lip as she gripped the other female tightly. Together they rode out their respective orgasms in relative silence, both reveling in the pleasure rocketing through their bodies. Over and over they both felt like the end was in sight, only for another twitch, or another spurt to keep things going just a little bit longer.

Even then, it couldn't last all night, and with a sigh, Limestone collapsed to the bed, her limbs falling slack in her bindings. Muad relaxed a moment later, the mare resting her head on Limestone’s shoulder and breathing deeply. Together they both remained there for several long moments, collecting their wits while filling their bodies with oxygen.

“That was… great,” Limestone murmured.

“You were exceptional,” Maud claimed, her voice lifting slightly.

Limestone grinned like she had just been given the greatest compliment of her life, which she may very well have. “So, did the spell work?”

Muad leaned backed, and ran a hoof down her chest to her belly. Where a small but noticeable bulge could be seen in her midsection.

“It seems like it,” Maud remarked.

“You still want to test it more don't you?” Limestone pressed.

“I do,” Maud admitted.

“We might as well do that then. It's not like I can go anywhere,” Limestone exclaimed, giving her restraints a jiggle for emphasis.

“I could loosen them for you,” Maud offered.

Limestone shrugged. “Nah. It seemed like you were enjoying yourself and I don't want to ruin that.”

“Because you definitely werent also having fun,” Maud pointed out with a small smirk.

The other mare blushed, and chuckled. “I don't know what you’re talking about.”

“So, round two then?” Muad asked.

Limestone nodded. “You know it.”

“Holy crap. I think you drained me dry,” Limestone muttered, hanging slack in her now loose restraints. “Seriously, I don't think I have anything left but dust.”

Sweat dripped down the matted fur of Limestone’s body, pooling on the sheetless bed they both lay in. Even Maud seemed to be winded, with the sweat stained mare breathing heavily as she sat on her sister’s crotch. Though the other mare’s cock was still buried deep in Maud’s pussy, neither pony seemed to be ready for another ride.

Maud hummed, and gently pressed her hoof against the now quite prominent bump in her midsection, causing it to jiggle the cum inside of her sloshing around within her overstuffed womb.

“You certainly have given me quite a bit,” Maud exclaimed.

“Do ya think that's enough to knock you up?” Limestone asked with a smirk.

“That's enough to knock up a small town,” Maud deadpanned, a small grin briefly crossing her face. “I love it.”

“I bet you can't wait until you start showing,” Limestone teased.

“It is going to be quite… interesting,” Maud murmured, her hoof caressing her belly in an almost loving manner.

“So, I don't know about you but I’m starving and need a shower something fierce,” Limestone offered.

“I had best get you out of there before you get rope burn,” Maud replied, untying one of the other mare’s hooves.

“I think it's a bit too late for that,” Limestone replied, rubbing her wrists once they were free.

“I am sorry my dear,” Maud murmured.

Limestone smiled, and gently caught the other mare before she could turn away, forcing their eyes to meet. “Hey now. It's fine. I’m a tough mare.”

“I should have stopped after round ten,” Maud stated.

“And stop me from filling you up to this point?” Limestone stated, poking the other pony’s cum belly. “No way.”

Maud smiled faintly, and planted a kiss on her sister’s lips. “Thank you dear.”

“Hey no problem,” Limestone murmured, blushing furiously.

“So does that mean I get to keep the rope around for next time?” Maud asked.

Limestone chuckled awkwardly. “I mean, it would be a waste to just throw out good rope right?”

Chapter 11

“You know it's been awhile since you left on that little mission of yours,” Limestone remarked, the pony continuing to thrust into a heavily pregnant Marble Pie’s plump pink pussy.

Who was in turn standing upright on a large bed while two of her sisters railed her from both ends. The mare in the middle was clearly pregnant with at least twins judging from the enormous size of her belly. Yet she didn't seem to be bothered by the added weight at all and continued to moan as Pinkie Pie fucked her throat ruthlessly.

The party pony bobbed her head eagerly. “We should totally take this chance to catch up a bit.”

“For sure” Limestone agreed, her hooves gripping Marble’s hips a bit tighter as she sped up her thrusts.

The dull thump of Pinkie Pie and Limestone’s cocks pounding into Marble’s well loved holes made conversation slightly difficult. As did the frequent moans, and slurping noises which came from Marble herself, who didn't seem to notice her sisters talking. All she seemed to care about was sucking cock and getting her pussy pounded like she was little more than a cheap whore.

“Why don't we start with what's been going on around here?” Pinkie Pie offered. “I only just got back from Ponyville and haven't even had the chance to catch up with anyone else around the house.”

Limestone chuckled. “Couldn't wait to sink your cock into Marble or mom huh?”

“Can you blame me? It's been days since I’ve been able to blow a load!” Pinkie Pie exclaimed.

“Not one bit. This is a damn nice ass,” Limestone stated, smacking Marble’s plush ass with a firm hoof in emphasis.

The other mare moaned lustily, giving her hips a little wiggle when she did so, jiggling Limestone’s cock around inside of her. Pinkie Pie couldn't help but grin at the sight, and take a brief pause to fill her nostrils with the wonderful scent of sexy mares. The stench of sex Pinkie Pie inhaled was thick, and hung over the room like a heavy, all encompassing blanket.

The smell would have made Pinkie Pie think of grungy hotels and sordid backrooms, if it wasn't for the wide open window next to her. With the bright rays of the mid afternoon sun illuminating everything it was hard to think of such dark places. Though having a beautiful mare eagerly throat fuck herself on Pinkie Pie’s titanic dick did make her imagine some less then reputable locations.

“We’ve been busy here,” Limestone remarked, grunting as she gave Marble’s ass another slap. “The addition to the house is coming along well like you probably noticed, although at this point the girls are getting pretty far along and can't help much.”

Pinkie Pie frowned. “We should be able to get it done before the babies arrive though, right?”

“With you here I’m sure it's feasible,” Limestone replied. “That is if you were planning on lending a hoof?”

“Of course I was!” Pinkie Pie quickly exclaimed. “I wouldn't want all my precious little foals to have to sleep in the same tiny room.”

The abnormally large bed beneath their hooves squeaked with every thrust, the brand new headboard thumping audibly against the wall. None of the mares seemed to mind nor notice this however, each one eagerly indulging in the pleasures of the flesh. None more so than Marble Pie who could barely keep her trembling hooves from dropping her to her knees.

The feeling of having her mouth and pussy crammed full of thick futa cock was not a new one to her. Pinkie Pie especially seemed to relish the opportunity to double stuff the mare whenever she had the chance. This even included filling Marble’s pussy alongside her other well endowed sister, though they hadn't done that particular move in quite a while out of fear of injuring the pregnant mare.

“I was just teasing you Pinkie,” Limestone replied. “I know you love this family just as much as the rest of us.”

Pinkie Pie smiled. “Thanks Limey.”

“Don't call me-” Limestone grunted, the mare biting back a moan. “Whatever. Is your friend Twilight going to be able to finish that teleportation thingy anytime soon?”

“Oh yeah, she is nearly- hold on a second Limestone,” Pinkie Pie pulled back and glanced down at Marble. “You okay down there? Felt like you were choking for a bit.”

“I’m fine Pinkie, just getting a little hungry is all,” Marble murmured.

Pinkie Pie giggled. “I can totally help you with, just give me another thirty seconds.”

“I’m not far either,” Limestone remarked.

Rather than respond normally, Marble merely opened her mouth wide, eagerly accepting Pinkie Pie’s turgid length back down her throat.

The part pony sighed. “Where were we again?”

“The teleporter,” Limestone replied, the mare licking her lips as she eagerly ran her hooves over Marble’s plush flanks.

“Oh right. Twilight was almost done before that whole thing with the chaos emeralds happened and she said it wouldn't be more than a day or two before we were linked to Ponyville!” Pinkie Pie happily exclaimed.

“That's great,” Limestone stated between grunts. “I’m glad you’ll be here more often. Maud’s getting pretty insatiable, and it's hard to please both her and Marble all by my lonesome.”

Pinkie Pie giggled. “No kidding. It's like they can't wait for us to put even more babies inside of them.”

Limestone stifled a moan. “No kidding. That's without even mentioning mom who has been an absolute attention magnet.”

“Oh man I’ll have to go find her right after this,” Pinkie Pie exclaimed, the pony releasing a shuddering moan of her own. “Stars and stones that's good. You ready Marbles?”

The pregnant mare nodded slightly, her spoken response coming out as little more than a gurgle.

Pinkie Pie grinned, and shot her other sister a look. “Ready to stuff this cute little pie full of cream?”

“You know it sister!” Limestone exclaimed, reaching up and clopping her hoof against Pinkie Pie’s.

Despite Marble being pregnant both Pinkie Pie and Limestone knew their shared lover enjoyed it when they got a little rough. Thus it was no surprise when they both shared a knowing grin before absolutely throwing themself into pounding the young mare from both ends. Cocks pistoned out of Marble’s holes at an incredible pace, the pony unable to do anything but moan whorishly as she was plowed from either side.

The sensation of having her body penetrated so deeply by both of her lovers was incredible, and for a moment it almost felt like the two futa mare’s dicks met in the middle of Marble. She knew that wasn't actually what was happening, but it was a hard image to dismiss due to their combined length. Thankfully the pounding waves of pleasure crashing all around her were more than enough to distract Marble from her strange thoughts.

The wet slap of cock meeting pussy and hips meeting lips nearly managed to drone out the collective moans of the three sisters. Sounds which grew louder and louder as their collective pleasure began to reach a peak they all saw coming. Sure enough it took only a few seconds longer before they all began to cum one after another.

Pinkie Pie was first to finish, the overstimulated pony gripping Marble’s shoulders tightly before ramming the now flared head of her cock down the other mare’s throat. The futa mare’s body became rigid, her emission considerable, and within seconds Marble could feel her belly begin to fill with cum. She herself wasn't far behind, and the moment she felt futa seed shoot into one of her holes, she too began to orgasm.

Limestone was last, with the pony letting out a shuddering sigh as she unleashed rope after rope of cum deep in Marble’s pussy. Though not nearly as titanic as Pinkie Pie’s release, it still put most stallions to shame, and filled Marble’s pussy in only a few short spurts. Limestone didn't keep her cock lodged in her sister’s cunt for long however, and she quickly pulled out, painting the grey mare’s backside white.

Marble herself barely even noticed as her back legs gave out, depositing her on the bed and leaving her with a rock hard futa cock rammed down her throat. The owner of which was so lost in orgasmic bliss that she didn't even move until her orgasm was beginning to wind down. By then Marble was beginning to grow light on air, prompting the pink pony to pull her dick from Marble’s throat.

The second her mouth was no longer stuffed with insectious futa cock, Marble fell onto her side, moaning to herself as her pussy continued to spasm weakly. Limestone stroked out the last few shots of cum on her sister’s heavily pregnant belly, smiling to herself all the while. Pinkie Pie followed suit, shrugging to herself as the last bit of her seed splashed across Marble’s round midsection.

“That was good,” Limestone murmured, the futa mare giving her dick a shake before hopping off the bed. “Now what was I about to do before I saw you two going at it?”

“Ahem,” murmured a familiar voice.

Limestone winced the second she laid eyes on the pregnant form of Maud Pie standing nearby. The mare herself wasn't quite as heavy as Marble, but it was close and no one was quite sure if she bore twins or not. One thing that was absolutely certain was the fact that she was quite irritated, and was absolutely dripping from arousal.

“You, me, my bed. Now,” Maud stated before turning and walking away, revealing her glistening pussy for all to gaze upon.

Limestone awkwardly cleared her throat. “Catch up with ya at dinner?”

Pinkie Pie nodded. “Sounds good, Limey. Have fun!”

“Don't call me… nevermind,” Limestone muttered before hastily trotting after her other pregnant sister.

“So,” Pinkie Pie clopped her hooves together and glanced down at her one remaining sibling. “Have fun Marbles?”

“Oh yeah…” Muttered the pony.

“Want some help cleaning up?” Pinkie Pie offered.

Marble shook her head. “I kinda like it actually. Think I’m just gonna lay here on the bed and enjoy it for a little bit.”

“Okie Dokie Lokie!” Pinkie Pie exclaimed, the pony bouncing off the bed. “I’m off to go say hi to mom.”

“Kay, have fun. I love you,” Marble murmured weakly.

Pinkie Pie grinned. “Love you too Marbles and don't worry we will!”

Chapter 12

Pinkie Pie bounced excitedly through the rock farm, slowing significantly when she neared the partially complete extension being added to her house. Though they were only expecting five or so foals, a dozen rooms were in the process of being built. Which had the added effect of making the existing home seem like the addition in comparison to all the new construction.

So far everything had been framed, and had a roof, but that seemed to be about it. Pinkie Pie made a note to get a little help from her friends once the teleportation circle in the front of her home was done. Which, unlike the extension, appeared almost entirely complete, at least to Pinkie Pie’s untrained eyes.

The magical circle was nearly ten metres across and absolutely filled with strange symbols Pinkie Pie didn't understand. The only thing that seemed to be missing was whatever part that should be at the very center of the complex array of runes. Right now the innermost section was completely barren and was waiting for Twilight’s final visit before it was filled.

The mere thought of being able to jump back and forth from Ponyville to her home made Pinkie Pie bounce even higher than before. No longer would she have to choose between her friends, and her family. Even better, she would be able to connect said family to the town she loved almost half as much as them.

Already plans were forming in the pink pony’s mind, ideas for parties both big and small taking root in her noggin. Now wasn't the time, she reminded herself. She had to get back to the task at hand and Pinkie Pie quickly turned her attention to the north side of the rock farm.

To where a small brook burbled its way next to a small copse of trees she knew her mother liked to relax next to. Bounding her way across the rocky expanse, Pinkie Pie quickly picked up the faint sound of running water. A second later and she found three familiar trees as well as a patch of grass upon which her mother lay on her side.

The older mare’s gaze was distant, a hoof absently rubbing her massive belly while she watched the water pass her by. So absorbed in her thoughts was the pony that she hardly even noticed Pinkie Pie approach until the bouncing mare was only a few feet away.

“Hey mom! Enjoying the shade?” Pinkie Pie inquired.

Cloudy Quartz smiled as she turned to the younger female. “Oh my dear Pinkie Pie. How wonderful it is to see you. Yes, I am enjoying it quite a bit. Why don't you join me?”

Pinkie Pie laid down next to her pregnant mother, the young mare resting her chin on Cloudy’s belly. “So, whatcha thinkin about?” Asked Pinkie Pie.

“Nothing in particular,” Cloudy Quartz remarked as she ran a hoof through Pinkie Pie’s mane. “Names mainly, but now I can't help but think how good it is that you’re home.”

“Daww, I missed you two,” Pinkie Pie replied, leaning forward and giving her mom a brief kiss on the lips.

“It has been far too long since we,” murmured the elder mare before trailing off. “We will have time for that later though. How was your adventure?”

“Not bad,” Pinkie Pie began, rolling over onto her back. “We had to fight a bunch of robots and this really angry red dude.”

“Red dude?” Cloudy Quartz inquired.

“It doesn't matter,” Pinkie Pie quickly replied. “What does matter is that we saved all the animals and got the important artifact doohickies back to their rightful owners.”

“Well that's good,” Cloudy Quartz remarked. “And the teleportation circle? When is that silly thing going to be complete?”

“Soon!” Pinkie Pie happily proclaimed. “You should be happy you know. You won't have to haul rocks all the way to the village anymore.”

Cloudy Quartz sighed. “I know. It's just hard to get over my distrust of magic, even after all this time.”

“Well don't you worry your pretty little head!” Pinkie Pie declared. “Twilight is on it, and she said she’d have it done in no time at all.”

“And this friend of yours, does she know about…” Cloudy Quartz gestured to her belly.

Pinkie Pie giggled. “She sure does, and she even has a similar story of her own.”

“Oh really, so she is endowed like you?” Cloudy Quartz continued.

“Yupper doodle,” Pinkie Pie replied.

“Interesting. Maybe you should invite her over some time for dinner,” Cloudy Quartz offered.

“Sounds good, but let's not worry about that right now,” Pinkie Pie exclaimed, hopping up. “You need some lovin, and Pinkie is eager to give you just that.”

Cloudy Quartz blushed. “I have become quite randy recently and not even that plastic toy you bought me not long ago is able to scratch that particular itch.”

“Don't you worry mommy dearest. Pinkie Pie is on the job!” Pinkie Pie exclaimed, grinning excitedly.

“Just go slow,” warned Cloudy Quartz, turning onto her back and spreading her back legs ever so slightly. “I’m getting awfully heavy and fairly far along.”

“Oh I know,” Pinkie Pie remarked with a grin. “You’re somehow getting even sexier too!”

The older mare blushed. “You always know what to say to make an old mare feel beautiful again.”

“Pisha, again? You never stopped being beautiful, mom!” Pinkie Pie replied, crawling up to the other pony. “In fact I don't think you’ve ever been anything less than stunning since as far back as I can remember.”

Cloudy Quartz shuddered, stroking the other mare’s chin with her hoof. “Take me you gorgeous stud you.”

“Don't mind if I do,” Pinkie Pie exclaimed, the mare eagerly lining up her hard futa cock with Cloudy Quartz’ glistening pussy.

The first incesteious inch slid inside without resistance, the older mare releasing a soft sigh as she felt herself be penetrated. Rather than become excited by this development Cloudy Quartz could only feel relief at having her daughter’s thick futa cock begin to press inside of her. It had been too long, and the sensation of having her pussy spread around the thick head of Pinkie Pie’s dick was just what she needed.

“You feel so good inside me,” murmured the pregnant mare.

“And you feel really good to be inside of,” Pinkie Pie replied, planting a soft kiss on her mother’s nose.

“Just remember to go slow at first. You aren't about to hurt me or our foals but I still want to take our time,” Cloudy Quartz warned, a hoof pressed against Pinkie Pie’s chest.

“Of course,” Pinkie Pie replied quickly, bobbing her head. “I gotta make up for lost time. Which means staying inside of you as long as possible.”

Cloudy Quartz’s cheeks glowed faintly with a soft blush. “That reminds me of last time where you insisted on sleeping with your cock inside of me.”

Pinkie Pie’s eyes went wide. “I’ll have to do that again tonight! That way I can make sure to give you plenty of belly rubs.”

Cloudy Quartz shuddered briefly as she felt several more inches of futa cock push their way inside of her. “That would be lovely dear,” she murmured.

Pinkie Pie grinned, and began to run her hoof across her mother’s bulging belly, gently caressing the mare’s soft skin. A second later and the expecting mother’s eyes went wide when a little hoof became visible through her flesh.

“Oh my. It seems like our little ones know their daddy is here,” Cloudy Quartz remarked.

Pinkie Pie’s smile quickly grew to encompass her entire face, and the pony gently touched the bulge with her own much larger hoof. “Hey kiddos. I can't wait to get you out of there. I have so many birthday parties planned for you and all your siblings!”

Cloudy Quartz gently took the other mare’s chin in her hoof. “You’re just saying that because you want to fuck a few more of them into me.”

Pinkie Pie’s cock twitched excitedly inside of her mother’s now quite full cunt. “I really do want to meet them, even if it means you won't have a big round belly for me to love.”

“Don't worry. It won't be long until my womb is full of your foals once more,” Cloudy Quartz murmured as she leaned in for a kiss.

“Our foals,” Pinkie Pie corrected before their lips met and they began to kiss one another in earnest.

Their mouths opened, and closed, their tongues briefly brushed against one another while their bodies remained pressed tightly together. All while Pinkie Pie’s hoof continued to rub across as much of the pregnant mare’s belly as she could manage given their current position. Cloudy Quartz wrapped her back legs around Pinkie Pie’s middle section, holding her daughter close as they continued to make out.

Even while kissing her mother passionately and rubbing her belly, Pinkie Pie continued to move her hips in a slow gyrating motion. The sensation of parting her mother’s folds around her own hard cock made the young earth pony utter a low groan of pleasure. While at the same time Cloudy Quartz moaned as well, the feeling of completion nearly overwhelming the pregnant mare.

Using one of her free hooves Cloudy Quartz gently grabbed the back of Pinkie Pie’s head, ensuring the young pony couldn't break the kiss. Though it wasn't like that was going to happen anytime soon, as the futa mare relished the taste of her mother’s soft lips. More than seeing the farm again, or walking in the front door of her childhood house, resting balls deep inside of her mother’s pussy felt the most like returning home.

Here she was warm, cozy, accepted, and loved. Here Pinkie Pie had everything she could ever hope to desire. A soft velvety hole to stuff her cock into, a pair of velvety lips to kiss, and the welcoming embrace of a pony who loved her whole heartedly.

As they lay there, lips and hips locked together tightly, both ponies couldn't help but consider just how good it felt to be there at that moment. They were content in ways neither had ever experienced before in their lives. So they stayed like that for as long as they could, with their soft, whispered moans being the only sound to break the relative quiet.

It was as if they worried that uttering a sound would shatter the illusion, for as the minutes dragged on they continued to say nothing. Instead they let their bodies speak for them, with their hooves touching and caressing one another with a quiet, burning passion. Their eyes remained glued on another throughout it all, only looking away briefly when the falling of a leaf caught their attention.

Pinkie Pie’s hips continued to shift and gyrate, pulling back only ever so slightly before being shoved forward once more. The constant deep movement left Cloudy Quartz gasping and shuddering, pleasure coursing up her spine in a constant stream. The older mare’s hooves remained locked around her daughter, clinging to the other earth pony as if her life depended on it.

For a long while there was only the soft caress of the breeze, the gentle touch of their lover’s hooves, and the endless ocean of bliss they drifted atop of. The faint scent of fall was almost completely taken over by the smell of sex and sweat which quickly filled the area. Neither pony cared however, as the pair had spent many, many hours in just such a position before and had thus grown quite used to it.

Occasionally Pinkie Pie would switch hooves in order to give one of her limbs a bit of a break, and Cloudy Quartz would sometimes loosen her grip momentarily. Other than that Pinkie Pie merely continued to rub, kiss, and gently thrust inside of her mother with a careful, patient manner. Though their love making was slow, it was passionate, and both ponies could feel the undercurrent of burning desire which they held for one another.

This ever present feeling of nearly overpowering lust could be seen in their eyes whenever their gazes met.

Time slipped past them at a steady pace, seconds turning into minutes slowly but surely. Only when the first hour threatened to pass did either pony dare to break the collective trance they had fallen into. The expectant mother was nearing her first powerful orgasm as was her daughter, who remained balls deep inside of her.

They could tell from the quickness of one another’s breath that it wouldn't be long now, and it was a good thing too. Though strong, their hooves were beginning to become exhausted, and even Pinkie Pie was beginning to grow a little tired of holding herself up. Though if it meant staying like this longer both parties knew they would allow their limbs to fall asleep and for weakness to sap their hooves of strength.

They had all the time in the world however, and thus allowed themselves to fall victim to their pleasure. Cloudy Quartz’ hooves grew tighter around Pinkie Pie’s torso while the futa mare thrusted a little faster and a little harder. All while their kiss became more constant, with neither party willing to separate from another for more than a second to catch their breath.

Then they would meet once more, hungrily making out as they rutted one another in an increasingly desperate manner. Their moans grew slightly louder, the soft slap of flesh meeting flesh adding to the orchestra of ecstasy they played for one another.

And then it happened.

Pinkie Pie drove her hips forward one final time, ensuring her hips were flush against her mother’s as her cock head flared. Hot cum splashed against the sealed barrier to Cloudy Quartz’s womb before filling her love canal utterly. There it mixed with the hot feminine cum that gushed forth from the pregnant mare’s body which quickly squirted out of her overfull hole.

Their bodies shook and shuddered in unison as they kissed one another in a ravenous fashion. This brief burst of intensity quickly fell away, with both parties laying still and their foreheads pressed against one another. Together they looked down at Cloudy Quartz’s enormous belly, cum continuing to dribble out of the pregnant mare’s aching sex.

They remained like this until finally their orgasms had run their courses and there was nothing left to do but slowly untangle themselves. Hooves parted, bodies separated, though through it all Pinkie Pie made sure to keep her semi hard cock deep inside of her mother. Together they twisted until they lay upon their sides, legs intertwining once more as they nestled between a set of tree roots.

Pinkie Pie sighed. “I love you mom.”

“I love you too Pinkie Pie,” Cloudy Quartz replied.

Chapter 1

Pinkie Pie sighed as she placed her pickaxe on the ground and leaned heavily on the handle. The last few weeks had weighed heavily on the party pony, and the results of these changes were evident across her body. The baker had gotten rather used to her cushy and far less physically demanding job in Ponyville, to the point that she had begun to pack on the pounds despite her frankly ludicrous metabolism and cardio filled life.

Pounds that she was now shedding like nobody’s business now that she was back home and working full time on the farm. Not like she was complaining mind you, but the party pony felt a little useless as she took her third break of the day, her breathing coming in sharp, labored gasps as she struggled to stay standing. Sweat dripped down her body and for a second the pink pony’s legs quivered, before giving out completely and making the mare land on her butt with a soft thump.

“Thank goodness for my junk filled trunk.” Pinkie Pie muttered to herself.

The mare placed her pickaxe aside and wiped her hoof across her forehead, mopping up what felt like gallons of sweat. Pinkie Pie leaned back and looked up at the bright mid afternoon sky, a sigh on her lips. She was sweaty, stinky, and utterly exhausted, and still there was a metric ton of things to do, so many in fact that the party pony could confidently say that she was now more stressed than she had been in months if not years.

And that was without mentioning the fact that her parents had recently gotten a divorce.

Sure it had been amicable, and semi mutual, but Pinkie had overheard a whispered conversation between the two, in which Cloudy admitted that there was a hole in her life that he simply couldn't fill. Though it made Pinkie feel better to know that it was at least half way mutual, that didn't dismiss the fact that the party pony had to leave her comfy life behind in order to help out on the farm. It also made Pinkie Pie realize that maybe all the little assumptions she made about her parents were wrong, as the party pony had always assumed they would stay together forever. Either way Pinkie Pie kind of hoped that her mother found someone else, or hired some extra help, as she wasn't cut out to be a rock farmer anymore.

As she sat there in the sun, Pinkie Pie couldn't help but think back to everything she had left in Ponyville. From the job, which Mrs cake had been kind enough to say would always be there if Pinkie Pie decided to come back, to the friends she had left behind.

“Silly pony, you didn't leave them behind.” Pinkie Pie corrected, tapping the side of her head with a hoof. “You can go visit them at anytime remember?”

Despite her encouraging words, Pinkie Pie’s brain didn't seem to want to listen and the mare closed her eyes and tried to force her mind to think of something else. She sat there struggling for a long time, the party pony wanting desperately to leave the dark thoughts behind and to think of things in a less black and white fashion lest she succumb to her own inner turmoil. She remained there for several long minutes, eyes shut tight, sweat cascading down her body and further reducing her fur to a matted, disgusting mess. In the end she growled and flopped onto her back, staring angrily down at her crotch, and the dick that sprouted from there.

“And what am I supposed to do with you?” Pinkie Pie asked angrily before her head fell back, and the party pony groaned in exasperation.

“As if being away from my normal friends was bad enough, but out here the closest sex friend is over a two hour walk away.” Muttered the pony, whining to noone in particular. “This is awwwwful.”

“Unless…” Pinkie Pie suddenly shot up, a hoof rubbing her chin as she considered the few options laid out before her.

There was always the option of sprinting all the way back to Ponyville, and fucking the brains out of whomever she could find until she finally burnt herself out and ran back to the farm. But she didn't have two days to spend fucking and running back and forth from the farm, so that was unfortunately out.

Jacking off did little to help matters, and Pinkie Pie had never been the best at giving hoof jobs, even if they were just to herself. So with a resounding sigh, that was marked off the list as well, leaving Pinkie Pie with only one option, though it was a long shot.

“Marble was pretty tight that other time.” Pinkie Pie muttered. “She moans really loud and does that thing with her butt when she's about to cum…” The party pony groaned and fell back to the ground, limbs splayed in all directions, hoping against hope that the cold stone ground would dampen the white hot lust that burned inside her.

“That wouldn't work either, she's my sister, and also we were like super young so that doesn't even count I don't think.” Pinkie Pie explained to noone at all.

With another groan of irritation, Pinkie Pie hefted herself back into a sitting position. “Well I gotta do something.” The mare sighed, looking down at her hoof dejectedly. “Come on righty, time for round three of paint the rocks white.”

Lifting herself into a standing position, Pinkie Pie took a nervous glance around before creeping off towards the ill used south field while making sure to keep an eye out for her sisters. Seeing noone, and nothing other than dust, rocks, dirt and a solitary tumbleweed bounding across the field, Pinkie Pie relaxed.

It didn't take her long to find a nice spot to jack off, a small crevice appearing out of the ground, and giving her just enough privacy to sneak inside of it and masterbate without being seen. The party pony ignored the crystals she saw growing in the small six foot deep crevice and instead gripped her cock tight in her hoof.

Pumping a hoof back and forth Pinkie Pie closed her eyes and tried to imagine something sexy to help herself along, the mere act of touching her stiff erection not being enough for her. Yet try as she might, no matter who she thought of, or what she imagined, Pinkie Pie couldn't seem to think of anything that really tickled her fancy. Even imagining that one time where she had fucked Rainbow Dash in the weather factory hadn't helped matters, and that was like Pinkie’s go to beat off material that wasn't zero g jugs, and she didn't have her magazines on her.

Grumbling silently the mare groaned aloud. “Oh come on you stupid thing, just cum already.”

Shaking her dick angrily did little to help her orgasm situation, but it did feel kinda cathartic to take out a bit of her aggression on the offending appendage. When shaking it also didn't work, Pinkie Pie closed her eyes and tried to think back to the last thing that had really made her hot and bothered, only to realize it had only been a few minutes ago, when she had remembered that time with Marble.

Pinkie Pie considered stopping there, or thinking of something else entirely, but her dick twitched expectantly when Pinkie imagined her sister, and the party pony was not leaving this depressing hole in the wall unless she had managed to relieve herself. With a shrug, Pinkie ignored the moral quandary around jacking off to the thought of her sexy sexy sister, and instead imagined Marble teasing her seductively.

Pinkie’s imagination conjured images of the young mare rubbing and grinding herself up and down a pole, her body gyrating to some upbeat music playing in the distance. Instantly Pinkie Pie’s cock began to twitch needfully, and the party pony stroked it vigorously, her imagination doing wonders at making her orgasm come faster.

“Yeah, that's right, work that pole.” Pinkie whispered, imagining Marble was stripping just for her.

The imagined Marble continued her sexy dance, the normally shy pony revelling in the wanton lust and flashing Pinkie Pie her privates nearly constantly. The view was exactly what Pinkie wanted to see and thus she imagined Marble doing it more often, the pretend pony pressing her crotch against the pole as she dragged her wet pussy up and down the peice of metal.

A bead of precum dribbled down the mare’s length and she couldn't help but moan aloud, her pent up desires getting the better of her. If she was in a sound state of mind she may have wondered if it was a good idea to moan so loudly, in such an odd place, but Pinkie Pie was rarely in a sound state of mind, and certainly wasn't at that exact moment.

She continued to stroke her cock harder and faster, pursuing the physical release that came with orgasming, and less the pleasure that came with the act itself, the mare well aware of just how little time she would have before someone came looking.

Dream Marble continued to dance for almost a minute longer until Pinkie Pie couldn't take it any longer and dismissed the pole entirely before leaping up onto the stage and mounting the mare in a single fluid motion. Pinkie Pie was unbothered about the impossibility of such a thing, focused purely on just how good it felt to imagine herself mounting and fucking the hell out of her sister in such a debauched manner.

Their sexes met, squelching wetly as their hips were pressed against each other, Pinkie Pie’s cock as deep as it could possibly get in a single titanic thrust. Marble’s loud moaning filled the air, and a single sniff of the air told Pinkie Pie that her sister wanted this as bad as Pinkie did.

The mare’s real hoof moved faster, gripped tighter, Pinkie Pie desperate to get at least a small sense of relief before anyone realized she had wandered off alone again and tried to come find her. Her moaning grew louder, and more debauched as the imagined Marble put her hooves up and braced herself against the wall while dream Pinkie fucked her.

Dream Pinkie Pie continued to rail the mare with reckless abandon, the real Pinkie bucking her own hips in time with what she what was imagining. The party pony imagined what the little bulge she would see on her sister’s stomach would look like if she craned her head in order to catch a peek. And she knew it would be there if Pinkie Pie looked, the shy mare being so thin that the party pony knew from experience that she would be able to easily see the bulge that not only her flare made, but also the mid point of her dick.

As she imaged Marble going faster, the mare’s hips becoming a blur of movement, Pinkie Pie’s hooves gripped her waist and heldon for dear life. Pinkie Pie didn't notice that her own real voice was becoming louder still, growing to the point that she was almost screaming in ecstasy. Not wanting to let up on the best masterbation session Pinkie Pie had experienced in over a month, the party pony continued, utterly heedless to her surroundings.

After only a few minutes Pinkie Pie could already feel her orgasm coming closer by the second, the mare eagerly awaiting the release that would come after her hormones finally died down for a little bit. “Come on, come on, I’m so close.” Pinkie whispered, her hoof becoming a near literal blur as she stroked her cock as fast as equinely possible.

Imagination Marble was moaning and whimpering Pinkie’s name over and over, the fake pony begging be cum inside of, to have her womb painted white with her sister’s hot seed.

Upon hearing that imagined bit of dialogue Pinkie Pie knew her orgasm was secured, and just before she began to cum, she heard something that broke her out of her fantasy and made her spin around. “Honey, are you alright?” A gentle voice asked.

Their eyes met, and for a second Pinkie Pie thought she would be able to hold back the wave of cum she felt churning inside of her. Yet her body and orgasm had other plans, and after a twitch, the party pony’s cock erupted with seed, shooting a heavy stream directly into Cloudy Quartz’s face. The two mare’s shared the same shocked expression as Pinkie’s dick erupted over and over, covering the older mare’s features in hot seed.

When finally the party pony’s pocket party cannon died down, and began to soften, Cloudy Quartz’s fur had been nearly completely matted. A particularly thick wad of seed having also landed on her tongue where it was apparently forgotten of in the heat of the moment. Pungent mare seed dripped down the older pony’s face and neck, staining her fur and ruining her mane.

Pinkie Pie winced. “I can explain?” She half asked half stated.

Chapter 6

“Was Marble okay?” Maud asked, in her usual, monotone voice.

Limestone nodded and slipped beneath the covers, sliding her body in behind Maud’s and pulling the other pony in close. “She had another night terror and was being comforted by Pinkie Pie and mom.”

Maud nodded, and wiggled her body slightly, pushing herself against the other mare’s chest. “That is good. I worry about her.”

“Yeah…” Limestone muttered, the pony resting her head on the crook of maud’s neck. “I know Pinkie Pie and mom will help her out but I still wish she had come to us first.”

Maud gently squeezed the other pony’s forehoof. “Its okay. I’m sure she just didn't want to interrupt us.”

“I suppose.” Limestone sighed. “On the flip side they will be occupied for the foreseeable future so we could have a little fun guilt free.”

“True.” Maud agreed, her voice rising slightly. “We do have a few more condoms left as well.”

“Hopefully we have enough to tide us over until we head back into town again.” Limestone muttered, reaching under the bed and grabbing one of the aforementioned condoms.

“If not you may have to fuck me raw a few times.” Maud stated.

Limestone shot her sister an odd look, the pony able to pick out the slight excited edge to Maud’s words. “Oh you’d like that, wouldn't you?”

“I may.” Maud stated evenly.

Limestone shook her head. “We’ll cross that bridge if we ever get there.”

“Don't you mean when we get there?” Maud shot back.

The grey maned earth pony snickered. “Oh Maud, your such a slut.”

“Only for you.” Maud replied quickly.

“So are you going to put this condom on me, or are you going to make me do it?” Limestone shot back, waving the condom in front of Maud’s face.

Maud smiled ever so slightly. “I can do it. There has been something I’ve wanted to try on you.”

“Oh really now?” Replied Limestone, who pulled back the covers. “Then go ahead, show me this trick of yours.”

Maud smiled faintly, the barest edges of her lips turning upright. “Okay, just sit there, and spread your legs.” She commanded.

Limestone did as she was told, sitting on the bed with her legs spread, waiting patiently for whatever Maud had in mind. She watched as the other pony pulled the condom from its wrapper before placing it in her lips, making Limestone cock her head slightly. “What are you-” Was all she managed to say before Maud’s firm hoof stopped her question.

Frowning, the pony sat back and crossed her forehooves over chest, patience quickly bleeding away.

Maud didn't make her wait for long though, and the mare lined her lips up with Limestone’s rock hard cock. After a second of adjustment, she placed her lips against the tip, and pushed forward, gently at first, and then faster as she got the hang of it. Limestone couldn't help but moan, her shock overriding her usually quiet demeanour.

In seconds, the condom was on, and Maud’s nose pressed firmly against her sister’s crotch. Pulling back, Maud smiled at her handiwork, and sat on the bed. “What do you think sister?” She asked.

Limestone smirked and tackled the pony to the bed, pinning the mare down and lining up her cock with the other pony’s already wet pussy. “I think you are an incorrigible slut who spends too much of her day thinking of my dick.” She spat with a smile.

Maud shivered slightly, the edges of her lips twitching the slightest bit. “So are you going to fuck me or what?”

“Oh I’m going to fuck you alright, you dirty slut you.” Limestone replied before spreading her sister’s legs wide. “I’m going to fuck you so hard that your going to spend all day thinking of what I did to you.”

“Oh my.” Muttered Maud, who merely allowed her sister to do whatever she pleased with her body.

Limestone grunted, and lifted Maud’s back legs up, slipped her forelegs under, and leaned forward, pinning the other mare under her. “You can bet your ass I will. Every time you move, every step you take you’ll ache and be reminded of what I’ve done to you, of what a slut you are.”

Maud shivered again, and the tiniest of moans slipped past her lips as her forelegs spread, supporting her weight. “But sister, then I will spend all day wet. You wouldn't want that, would you?”

“I’ll do whatever I want with your body.” Maud declared, pushing her hips forward and aligning the head of her dick with Maud’s slick entrance. “Your mine to fuck however, whenever I want. So if I want to bend you over in the middle of the day and fuck you, I will.”

“Oh sister, thats so naughty.” Maud whispered.

Maud smirked, and thrust her hips forward, burying a few inches of her throbbing length in her sister’s pussy. “Not nearly as naughty as constantly fantasizing about your sister’s thick cock and wanting her to fuck a baby into you.”

The tiny, almost unnoticeable blush that spread across Maud’s face may as well have been a skylight for how obvious it was to Limestone. “I never said that.”

“You don't have to say it.” Replied Limestone, who thrust forward again and again, until she was balls deep in her sister’s dripping honey pot. “Your desire for me to fuck you raw all the time tells me all I need to know.”

Limestone began to work herself into a decent rhythm, her pace slow, but her every thrust powerful and deliberate. Soft pieces of fabric had been deliberately placed between the headboard and the wall, meaning no matter how hard Limestone plowed her sister’s pussy no one would ever hear. A fact that Limestone knew and took advantage of more than usual, given that the closest other family member was across the house.

Each thrust began at the very entrance to Maud’s pussy, with Limestone’s cock almost pulling all the way out before slamming forward with all the force of a hammer blow. Each time her balls slapped against Maud’s ass, Limestone could hear her sister breath a little harder. It was a small, but noticeable thing that made Limestone grin from ear to ear, knowing full well how much Maud was enjoying herself.

“You love it don't you?” Limestone asked, her every word punctuated by a hard, pounding thrust of her hips. “How I fuck you long and hard.”

“It is… acceptable.” Maud replied slowly, and deliberately.

Limestone knew the signs well, and could tell that her sister was really getting into it. “Go on, tell me you love it.” The mare commanded, punctuating her demand with an even more powerful thrust. “Tell me you crave it, that you need my cock more than anything else in the world.”

“I… need it.” Maud whispered, the pony showing an uncharacteristic amount of emotion.

Limestone smirked, silently thrilled at getting a response from her reserved, and quiet sister. “Tell me you crave it, that you love it. Or else I’ll stop.” Threatened the futa mare.

“You wouldn't.” Maud replied evenly.

Still smirking, Limestone pulled all the way back, and stopped in place. “Watch me.”

For a moment the two mares stared at one another, until Maud’s cheek twitched. “You win. I need it.”

“Oh, what was that?” Limestone replied, leaning closer. “I didn't hear you.”

“I need your cock. I love feeling it inside me, and I would love to carry your foals.” Maud replied, her voice rising ever so slightly.

Limestone grinned and flew forwards, burying herself once more in her sister’s pussy. “That's what I want to hear. Your such a good little slut. I’ve trained you so well.”

“You made me this way. You better take responsibility.” Maud stated.

“Oh don't worry my little cum dump, I’ll never stop fucking this tight little hole of yours.” Limestone shot back before planting a chaste kiss on her sister’s lips.

It wasn't much, but for the two rather less affectionate sisters, it was a deep sign of love, and made both mares blush, one more than the other. Immediately things changed, became more intense, and neither pony could bring them to speak any longer. The short ritual of domination, and subjectation was over, and Limestone’s utter dominance of her sister was assured once more. With that out of the way both ponies felt it was easier to let out their inner most passions, which came in the form of fucking like a pair of lovers who hadn't seen each other for years.

Limestone continued her relentless, and powerful thrusts, but sped up slightly, punctuating every thrust with a small moan of pleasure. This in turn made Maud feel more okay with doing the same, the pony all but whispering her moan back. At the same time, the laconic mare was pushing back against her sister, rocking her hips as much as the position allowed. Which wasn't much, though Limestone appreciated it all the same, the small show of appreciation emboldening her even more.

She almost considered stopping and removing the condom, but decided against it, choosing to continue to rail her sister knowing that she couldn't get impregnated by it. With that knowledge in mind, she sped up even more, the minutes passing at a blur as both ponies fell into a well rehearsed rhythm. Hundreds of hours spent rutting in near silence, sometimes while their family was in the next room had turned them into sexual ninjas of some kind and whenever they got into it, they inevitably fell into their old routine.

And when they fell into it, they fell hard, the two ponies fucking hard, and fast, as if someone might walk into their room at any moment. Not like they minded, of course. After all, they had gotten quite used to passionate, yet short bouts of intercourse. Within only a few minutes, they were both panting hard, and staring deep into one another’s eyes.

Then, they came within seconds of one another, the two ponies so in harmony with one another that they didn't need to speak in order to time it all perfectly. Maud only shuddered, the pony’s breathing coming a little faster as her forehooves squeezed at her sister’s shoulders. Limestone was a little louder, and a little less resistant to letting the world know how she felt, moaning long and hard. Throughout it all, Maud focused intensely on what it felt like to have her sister’s cock twitch and shoot cum deep inside her. It wasn't quite as good due to the condom getting in the way, but the earth pony still craved the sensation intensely.

After a while, Limestone’s grip lessened, and she gently laid her sister back down and slipped in next to her, Limestone’s cock remaining firmly wedged in her sister’s pussy. For a few minutes, there was silence, with both mares merely enjoying the quiet serenity that came now that their lust had been at least partially satisfied. Finally, Maud sighed, and gave her sister’s hoof a gentle squeeze.

“You should probably go back to your own bed.” She muttered with the slightest hint of sadness.

“Come on Maud, the rest of them will likely spend the night in mom’s room. We don't have to worry about being found out.” Limestone replied, squeezing her sister back. “Besides, I want to use you like a cock warmer all night long.”

Maud grumbled while blushing. “I suppose you have earned that much since mother and I are leaving for a while.”

“Exactly.” Limestone declared, giving her hips a little wiggle. “Besides, these condoms are really good, don't you want to see how far we can stretch them?”

Maud blushed a little harder and quickly decided to change the subject. “At least Marble will be there for you, right?”

Limestone gulped. “Err what are you talking about Maud?”

“I know about you and her.” Maud stated. “Its okay.”

Limestone sighed. “I’m sorry if it felt like I was trying to hide it but when you left for a few weeks I just… couldn't.”

Maud smiled, and gently ran her hoof down her sister’s. “Its fine. I know how you get.”

“T-thanks Maud.” Limestone muttered, only to smirk. “A better question is how are you going to survive with just mom for company.”

Maud chuckled. “I’ll be okay without you for a few days.”

“Are you sure about that?” Limestone teased, nipping at her sister’s neck. “Because something tells me you will be thinking of my big, fat dick every single night.”

“I might.” Maud replied with a hint of hesitation.

“Then I guess we better do it as much as possible before then, huh?” Limestone pressed.

Maud nodded. “I suppose so.”

Limestone licked her lips and pulled out another condom. “So, what are we waiting for?”
