“Alrighty Sis, the shower is all yours!” Pinkie cheerfully says as she saunters out of the bathroom and past Limestone who’s tapping her foot impatiently on the floor. Toweling off her head Pinkie’s cotton candy-esque hair springs back to its normal fluffy state.

“It’s about time, I’ll be lucky if there’s any hot water left!” Limestone grumbles, casting her eyes to the floor to avoid looking at her sister’s curvy frame. Pinkie, always having been blissfully uncaring about being nude around her sisters, began skipping down the hallway towards her room.

“Awww, don’t be such a grouchy grouch Lime. I know you missed me,” Pinkie chirps as she wraps Limestone in a hug from behind. The pink mare’s damp and supple bosom presses against her smaller sister’s back.

“Quit it!” Limestone groaned while wriggling out of her sister’s grasp.

“Well I’m going to hit the sack Sis, it was a long ride from Ponyville and I’m bushed,” Pinkie said as she released Limestine. “I’m gonna sleep like a rock,” the pink mare said with a giggle before disappearing into her room.

Limestone sighed and shook her head before entering the bathroom, closing and locking the door behind her. Stripping off her tanktop and shorts Limestone started the shower, taking a moment to look at herself in the mirror. Smaller in nearly every way than Pinkie her breasts were perky and athletic compared to her pink siblings massive udders. Inspecting her reflection Limetone gazed down her athletic frame before it drifted down to her crotch and the obscene marecock that dangled from it. Pinkie was the only Pie sister that didn’t sport a cock which wasn’t all that surprising given how much of an oddball the pink mare was anyways.

Stepping into the shower Limestone began lathering herself in the warm stream of water, her hands rubbing a bar of soap across over her velvety grey coat. Setting the soap down she washed her breasts and huffed, “Stupid pinkie and her fat tits,” the grey mare cupped her smaller bosom, “Think’s she so hot with those obscene things jiggling around all the time.” Looking back Limestone inspected her own sculpted rump, giving it an affectionate squeeze, “She wouldn’t be so squishy and soft if she had to work the farm every day like the resto of us!”

Thinking of Pinkie’s soft and supple frame Limestone felt a twinge in her groin, the thought of her sister’s ample tit flesh pressing into her back fresh in her memory. Reaching down Limestone started washing her cock, stroking its length with her soapy hands. Flashes of her pink sister’s jiggling ass skipping down the hallway flashed through her mind as she stroked her dick. Shaking her head and clearing her thoughts Limestone growled in irritation. Hopping out of the shower and wrapping herself in a towel Limestone stomped out of the bathroom and towards her bedroom, one door down from Pinkie’s.

As the grey mare passed Pinkie’s room she noticed that the door wasn’t fully closed. Limestone rolled her eyes and went to close the door but what she saw inside gave her a moment’s pause. Pinkie lay spread-eagle on the bed, fully nude and snoring slightly. Lime’s cock reflectively jumped at the sight and sinister thoughts crept into her mind at the sight. Looking back and forth down the hallway Limestone crept into Pinkie’s room and silently shut the door behind her.

Standing over Pinkie Limestone gazed across her pink sister’s form. Every part of pinkie was big, from her thick thighs and wide hips to her ample tits. “Stupid big titties,” Lime grumbled to herself as she reached down, digging her fingers into Pinkie’s obscene tit flesh. “Dumb fat ass,” Lime’s hand glided down her sister’s side, caressing her hip and outer thigh. Lime’s heart pounded as her hand began to ascend Pinkie’s leg and towards her pink-bushed snatch. Reaching Pinkie’s pussy Limestone gently ran her fingers across the velvety lips. “Stupid huff hot huff juicy pussy,” Limestone breathed as she stroked her sister’s moist marehood.

Limestone’s free hand wandered to her cock, slowly pumping its length as she rubbed her sleeping sister’s crotch. Panting as she continued to molest Pinkie Limestone shook her head and knit her brow before moving to the foot of the bed. Slowly crawling onto the mattress, as not to awaken her sister, Limestone move closer to Pinkie, pausing as her snout was just above the pink mare’s cunt. Inhaling deeply through her nose Limestone’s cock began to throb and leak precum at the pungent scent before her. The sheets under Limestone shifted and the grey mare went face first into Pinkie’s snatch, fortunately the pink mare was a heavy sleeper and only mumbled as her sister’s face was buried in her crotch.

Bolting upright Limestone panted, licking her sister’s juices from her snout the grey mare’s eyes went wide with lust as her cock throbbed painfully. Limestone’s instincts overtook her, reaching down she shuffled on her knees to position herself between Pinkie’s legs. Rubbing her cock on her sister’s crotch Limestone looked down at the sleeping mare with a lust-addled glint in her eye. Leaning back and positioning her cockhead at Pinkie’s entrance Limestone slowly pressed her hips forward, slowly burying her length into the pink mare.

“Unf,” Lime grunted as Pinkie’s dripping wet cunt gripped her thick marecock. Leaning forward Limestone leaned over her sister before pressing her face between the obscenely large tits and enjoying the mare’s scent. Grinding forward Limestone had gotten roughly half of her foot long cock into the pink mare before Pinkie started to stir. Limestone froze, half buried in her sister, as Pinkie lifted her hips slightly.

“Oh mister cupcake, give me all your frosting,” Pinkie mumbled fitfully.

Limestone wasn’t quite sure who ‘mister cupcake’ was but in all honestly she didn’t care. The grey mare started slowly fucking her sister, enjoying the moist and tight confines of her Pinkie’s marehood. “I’ll give you your frosting,” Lime whispered. Picking up speed Limestone shuffled forward again as she plunged a few more inches into the sleeping pink mare’s cunt. Reaching back the grey mare sunk her fingers into Pinkie’s flank as she continued to plow her sister. With a grunt Limestone nearly hilted herself into Pinkie and started jackhammering her cunt, feeling the blunt head of her marecock bump against Pinkie’s cervix.

“Nooooo mister Candycane I want don’t want to get off the ride,” Pinkie murmured as she locked her legs around Limestone, drawing her closer. Limestone gasped as her cockhead was forced into Pinkie’s uterus. The grey mare’s head was spinning at the nearly excruciating confines of her sister’s cervix.

“I just want you to know grunt that this is your fault,” Limestone wheezed as she continued to brutally fuck her sister. Thrusting her hips faster and faster as she felt herself reaching climax Limestone squeezed her sister in a tight embrace, burying her face in Pinkie’s chest fluff. Grinding her cock in balls deep Lime came, blowing liters of potent jizz directly into Pinkie’s womb. Grunting and heaving Limestone was forced to empty herself into her sister as Pinkie’s cervix milked every drop out of the grey mare. Pinkie’s legs relaxed and Limestone leaned back, her cock still locked inside her sister’s womb.

“Mmmmmmm, creamy creamy frosting,” Pinkie mumbled as she rubbed her cum swollen belly, drooling with a blissful expression on her face.

Limestone tried to pull herself free but to little effect. Reaching down the grey mare forcefully grabbed her cock and gave it a tug, popping it out of the pink mare’s womb before sliding it out of her sopping wet snatch. A torrent of cum lewdly spilled out of Pinkie’s marehood, seeping across the sheets as Limestone watched in awe.

“Well, like I said, you asked for it,” Limestone grunted as she stealthily climbed off the bed before wrapping herself in her towel. Leaving Pinkie to her dreams Limestone silently exited the room and walked back towards the bathroom to wash herself off. Just as she reached for the bathroom door Marble’s head poked out from an adjacent room.

“It’s nice having Pinkie back isn’t it?” Marble timidly asked with a smile.

“Yea sure, she’s alright when she’s not running her mouth,” Limestone replied before slamming the bathroom door behind her.

Marble winced at the sharp noise as Limestone disappeared. Maybe I’ll give Pinkie a visit tomorrow night, Marble thought, softly stroking her cock as she thought of the plump pink mare.

Marble awoke to footsteps passing by her room, cracking an eye open she noticed the sun hadn’t risen yet. Rubbing her eyes she stumbled to the door and peeked out to notice Pinkie’s rear as she descended the stairway downstairs.

“Sis?” Marble whispered at the retreating figure but to no effect. Stepping into a pair of slippers she kept by the door Marble exited her room as she went to follow her sister. Reaching the stairs she caught sight of Pinkie, completely nude, ambling towards the kitchen. ‘Oh jeez she must be sleep walking again’ Marble thought as she went to catch her sister before anyone else caught sight of her. Moving down the stairs as silently as possible Marble scampered after her. As she rounded the corner to the kitchen she caught sight of Pinkie, bent over the kitchen counter gnawing at the remains of a pie which had been left over from dinner the night before.

Pinkie’s prodigious rear swayed happily back and forth as she devoured what remained of the desert. “Mmmmmmm” she hummed as she greedily stuffed the pie into her face.

Marble stopped and blushed at the sight, even though Pinkie was her sister the sight of a curvaceous mare practically presenting herself stirred Marble’s loins. “Umm, Sis? You know you shouldn’t be snacking at this hour,” Marble murmured, trying her best to avert her gaze from the pink mare’s ripe behind. Edging closer Marble reached out to tap Pinkie on the shoulder but was stymied as Pinkie angled her ass towards her.

“Nooooooo, this is my pie! You’ll have to find your own,” Pinkie sleepily groaned before turning her dreamy eyes towards her sister, her pendulous breasts swinging as she moved

“Pinkie,” Marble’s blush deepened and as her marecock began to rouse itself. Noticing her cock begin to lengthen Marble pulled her shirt down in an attempt to quell the beast but to no avail.

“Heeeeey, what’re you hiding?” Pinkie fully turned to address Marble, still enchanted by whatever dreamscape in which she found herself. Taking a step forward Pinkie reached down towards Marble’s hands, now desperately trying to restrain her cock from springing into view.

“No no no no no,” Marble squeaked as she took a step backward. Unfortunately, due to the impeccable cleaning skills of their mother the floor had nearly a mirror finish and the grey mare lost her footing, tumbling backwards onto her behind. “Eeeek!” she quietly squealed as her hands went flying in an attempt to catch herself, her cock bouncing from beneath her night shirt.

“Ooooooh, I see. Someone was trying to be sneaky,” Pinkie cooed as she stood above marble, her arms akimbo as she sleepily looked upon Marble’s juicy cock. Sinking to her knees Pinkie slowly began crawling between her sister’s legs. Marble, to her credit, tried to backpedal but was halted as the larger pink mare grabbed her by the ankles. “Sharing is caring Mister Cupcake,” Pinkie groaned as she pulled her sister closer. Pinkie continued to pull herself closer to Marble until her nose pressed against the base of her sister’s shaft. “Mmmmmmm, I love eclairs,” the pink mare softly moaned as she ran her tongue up Marble’s length and to the broad cock head.

Looking down as Pinkie began licking and slobbering on her dong Marble stifled a moan, throwing her hands up to her mouth. Pinkie continued to lick and kiss along Marble’s length until she raised her head and practically inhaled the grey mare’s entire cock. Wincing and throwing her head back as Pinkie’s throat milked her marecock Marble writhed helplessly, trying fruitlessly not to enjoy the sensation of the phenomenal blowjob that her own sister was giving her.

Pinkie expertly bobbed her head up and down the bloated and throbbing cock flesh, her throat bulging with each plunge as nearly a foot of horse cock effortlessly slid into her mouth. How the pink mare was able to accomplish such a feat without gagging was beyond Marble let alone the fact that she was still sleeping while doing so. Despite the incestuous taboo the sheer sensory overload of the situation began wearing at the grey mare’s mind, it’d been far too long since she’d gotten this sort of attention. One of Marble’s hands slipped from her mouth and to one of her plump breasts, massaging and rubbing her nipple as her sister continued to service her. A small gasp escaped her as Pinkie withdrew the throbbing rod of grey flesh from her mouth, giving it a little kiss before looking up at Marble.

“I’m sorry Mister Cupcake, you look so lonely up there,” the pink mare whispered as she began to crawl up Marble’s supine form, her heavy breasts dragging across her sister’s frame. Pausing as her breasts pressed against Marble’s own bosom Pinkie dreamily looked down at her wide eyed sister before slowly reaching down to take each of Marble’s hands in her own. “You always did have the sweetest kisses,” the pink mare whispered. Pulling Marble’s arms to her side and pinning them against the floor Pinkie began to messily kiss her way up the grey mare’s neck towards her lips. Marble’s feeble struggles faded as the pink mare’s lips locked with her own, sloppy with pre-cum and sweetened by the pie she’d been devouring Marble thrust her tongue into Pinkie’s mouth.

Pinkie blissfully moaned as she felt Marble’s erect cock buck between her plump ass cheeks. As if on instinct Pinkie raised her hips slightly allowing the towering horse cock to find her marehood before bearing down and impaling herself upon it. Marble’s eyes shot open at the sensation, groaning into her sister’s mouth as she was enveloped by the moist confines of her sister’s snatch. Bucking her hips Marble began to mindlessly rut her sister as they continued to sloppily kiss, their tongues entwined.

Marble’s mind snapped, finally fully succumbed by the sensory overload as her hands flew to Pinkie’s hips. Digging her fingers into the pink mare’s juicy ass Marble began to senselessly fuck her sister, moaning despite herself at the irrationality of the situation. Arching her back Pinkie began to rhythmically bounce on Marble’s cock in tune with the thrusts.

“Come ooooooon Mister Cupcake I want that eclair cream!” Pinkie groaned as she reached down to harass Marble’s fat tits, twisting and pinching each nipple.

Marble’s eyes rolled into the back of her head, her tongue obscenely lolled out of her mouth. With a final grunt of effort she drove her entire length into Pinkie’s cunt, penetrating her cervix as her cock pulsed and swelled in climax. The grey mare’s cockhead flared, effectively locking itself into the pink pony’s womb as nearly a torrent of potent mareseed spewed forth. Pinkie shuddered as the sensation overtook her, causing her to climax and collapse atop her sister. The two lay nearly motionless on the kitchen floor save for the fitful thrust or two as Marble’s orgasm faded.

Catching her breath as her mind cleared Marble looked up to see Maud standing in the doorway wearing a nightgown, laconically looking upon the indecent scene before her. “Sis!” Marble blurted as she tried to scramble from beneath the now snoring Pinkie, “It’s not what it looks like.”

Maud stoically observed as Marble removed herself, her cock popping from the pink mare’s cunt and leaving a trail of jizz and juices behind. “So I didn’t just observe an act of incestuous carnality on the kitchen floor? How odd,” Maud monotonously pondered as Marble regained her footing.

“P…p….Pinkie just. And then the. B…b…but I was going to,” Marble stammered uselessly as she faced the apathetic Maud.

Maud calmly placed a hand on Marble’s shoulder, “I’ll get her upstairs and back in bed. I’d suggest you tidy the kitchen before mother or father awaken.” Stooping down Maud casually lifted and cradled the pink mare in her arms before wordlessly turning and proceeding towards the stairway. Marble scrambled to fetch a mop from the closet, her cock swinging as she darted about slinging ropes of mare seed across the already moistened floor. Maud shook her head at the absurdity of what she’d just witnessed. As she reached Pinkie’s room and lay the snoozing pink pony on her bed Maud looked down at her. Surveying the plump, full figured, mare Maud felt a slight tingle in her nether region…

Maud shook her head while looking down at Pinkie Pie, her luscious pink body sullied by lascivious juices and pie remnants caked on her face and hands. “As a responsible sister I can’t allow myself to leave you like this, not to mention the mess would only exacerbate the already questionable stains on your bed,” she droned, casting an eye at the sticky remains of Limestone’s foray earlier that evening. “Come on, let’s get you cleaned up a bit,” the grey mare intoned as she hefted Pinkie onto her shoulder before exiting the room. Quietly she proceeded to the bathroom while Pinkie gently snoozed, draped over her shoulder.

Entering the restroom and closing the door behind her Maud sat Pinkie down on the side of the bathtub, her fluffy pink hair acting as a cushion as her head rested against the wall. Reaching down Maud turned on the bath faucet, allowing the hot water to being flowing, before she stood and began pulling her nightgown over her head. As the nightgown rose Maud’s exquisitely thick marecock peeked into view, dark grey and vascular as it dangled from her loin. Maud’s cock wasn’t the longest between her sisters but it was definitely the thickest of the bunch.

“Mmmmm,” Pinkie mumbled, stirring slightly, “I smell cupcakes.” The pink mare’s head rose slightly as her sister stood before her. Blindly her snout rose and slunk forward before pressing itself against Maud’s flaccid member causing the grey mare to start.

“Pinke,” Maud droned, her head still enshrouded by the nightgown, “please refrain from your somnambular frivolities.”

“Awwww,” Pinkie whined, gingerly grasping the fat cock in front of her, “but I wanted to play with the balloon animals. Just gotta pump them up first.” The pink mare’s hand gripped the grey cock before her, squeezing and pumping its length while smiling mirthfully.

Pulling the nightgown from her head Maud looked down at her sister and sighed, “Let’s get you into the shower lest your shenanigans result in unforeseen consequences.” Maud pried her sister’s hand from her cock and stepped into the tub, pulling Pinkie Pie to her feet and in with her. Reaching around her sister’s squishy pink rump Maud leaned forward to switch the flow of water from the tap to the showerhead, causing warm water to begin cascading over the two.
Pinkie hummed happily as the water pattered across her body, running over her ample bosom and down her soft midsection. Opening her mouth she let the water sprinkle across her face and over her tongue. “Blech,” she spat and her nose scrunched up, “I wanted candy rain.”

“Pinkie the machinations of your subconscious never cease to amaze me,” Maud said while shaking her head behind her delusional sister.

“Mister foreman,” Pinkie twirled in place, “I wanted the candy rain! Can you fix it?” The pink mare’s sleep filled eyes affixed Maud while the two stood breast to breast.

“I’m neither a foreman nor qualified to operate the pegasi machinery needed for such an atmospheric event, should they exist in the first place,” Maud dully replied.

Looking down Pinkie studied Maud’s tits, while nowhere near as large as her own they were larger than Limestone’s and rivaled Marble’s in heft. Her dark grey nipples, contrasted by the surrounding light grey fur of her coat, stood out prominently in the chill night air. “Are these the controls?” Reaching down Pinkie Pie pinched a nipple in each hand, twisting and pulling them while falsely believing she were working some machine.

One of Maud’s eyes winced at the action but her demeanor remained unshaken. “Pinkie, if you continue to stimulate my erogenous zone my body will react. Please calm yourself,” Maud flatly stated, as if on cue her cock began to grow rigid, awoken from its slumber by the pink mare’s sexual stimuli. It grew in length and girth, erecting itself between Pinkie’s thighs until it kissed the pink mare’s vulva. “Oh my, I seem to have become aroused. No good can come from this,” the grey mare droned while looking down between her accosted tits to her rigid shaft.

“Oooooooooo!” Pinkie sleepily looked down at the turgic rod of flesh nestled between her thighs and against her marehood. “So this is where the candy comes from,” the pink mare purred as she reached down and wrapped her hands around Maud’s fat cock. Sinking to her knees Pinkie began stroking her sister’s dick, pumping her hands up and down its length as her muzzle hovered just in front of it. “Huh, maybe I gotta suck it out,” she whispered to herself as she wrapped her lips around the blunt grey cockhead, sucking gently as her hands continued to work the shaft.

Maud closed her eyes and sighed deeply, she was loath to admit it but Pinkie’s sleepwalking escapade wasn’t without its benefits. “Pinkie, as stimulating as your actions are I must ask that you stop. My phallus will not produce candy or confectionary of any kind,” the gray mare flatly stated although not resisting her sister’s impromptu blowjob.

“Mister Foreman!” Pinkie whined as she popped the thick marecock from her mouth, “Don’t be such a meanie pants.” Slowly she stood up face to face with Maud, crestfallen her dream filled eyes met her sister’s. “Maybe Mister Foreman would give me some rock candy instead,” the pink mare slurred as she placed her hands on Maud’s shoulders before hopping up and wrapping her legs around her sister’s sturdy hips. Pinkie’s marehood slid down Maud’s length before coming to a stop at the base. “Mister Foreman,” Pinkie whispered as she leaned in close, her snout just besides Maud’s ear, “I really do like hard candy the best.” With that Pinkie gave her sister’s ear a playful nibble and started gyrating her hips, her puffy pink pussy riding and grinding upon Maud’s meaty rod and slathering it in her juices in the process.

“You’ve left me no choice dearest sister, between your slick marehood stimulating me and your allusion to rock candy in reference to my penis you’ve done it, you’ve tipped me over the edge,” Maud stated while leaning back slightly, “I hope you’re ready for this because I’m a 10 on the mohs scale.” Angling her cockhead to Pinkie’s entrance Maud looked her sister in the eye, “Or, in layman’s terms, as hard as diamonds,” Maud groaned as she rammed her dick into her sister.

Pinkie squealed in delight and tightly embraced her sister, pressing her breasts tightly against Maud’s in the process. Maud apathetically reached around Pinkie’s plump hips, taking a firm grip before she began lifting and pounding the pink mare on her girthy marecock. The pink mare’s generous ass bounced up and down, the warm water of the shower running across her back and between her ample cheeks as she rode her sister.

“Hard candy was always my favorite,” Pinkie moaned lewdly as she rode her sister’s cock, her marehood clinging almost desperately each time the grey mare withdrew her length before ramming it back inside.

Maud pounded away, closing her eyes and enjoying the sensation of her sister’s warm and moist confines. With the slightest grunt of effort she spun in place, pinning her sister against the back wall of the shower. “Oh Pinkie,” Maud cooed monotonously, “The scintillating folds of your marehood caress me like the finest silt.” Bracing herself the grey mare began feverishly pounding the pink pony against the wall, her orange sized balls swinging and smacking against Pinkie’s rump with each thrust.

While still tightly squeezing her sister Pinkie began lifting and plunging her hips to meet Maud’s thrusts. Beset by whatever scandalous fever dream filled her head the pink mare depravedly ground her breasts into Mauds, their erect nipples rubbing and brushing past each other. “Oh Mister Foreman, you know how much I love when you talk dirty,” Pinkie groaned before leaning forward and sinking her teeth into Maud’s neck.

The grey mare fumbled and took a small step back at the action, her neck being an erogenous zone that, to her knowledge, only Boulder was privy to. Unfortunately for Maud the stimulation was all too much to bear: Pinkie’s juicy marehood sensually milking her cock, the warm shower water cascading off of her, their tits squeezed against each other, and now the passionate bite on the neck. Maud felt her balls tense as her body prepared to ejaculate, her marecock throbbing as her heart raced.

Unfortunately for Maud, just as she reached the peak of orgasmic bliss, the slick tub caused her to lose her footing. Slipping backward the grey mare fell to her knees, her cock wrenched from the cozy flesh sleeve in which it had been buried. Maud’s cock erupted as its flared head left Pinkie’s entrance, gushing her thick seed across the pink mare’s torso and up to her chin.

Pinkie ran her hands up and down her body, smearing Maud’s spunk across herself in a dreamy stupor. Hehehe, she giggled, “I’m like a strudel.”

Maud watched the display as her orgasm subsided, her marecock jerking with the last fitful spurts of cum. Sighing she stood, “Well that was, unfortunate.” Grabbing a bottle of shampoo from the inbuilt shelf the grey mare began lathering her sister, still sleepily fumbling with herself and quietly mumbling something about ‘candy island’. “Come on, let’s get you all cleaned up Pinkie. I still need to change your sheets after all and I’m sure Boulder will want to hear all about this.” Maud blandly stated while washing the pink mare.

After their shower Maud trundled Pinkie back to her room and changed her linens before tucking her in for the night. Looking over at the snoozing and well endowed mare Maud shook her head, thankful to have such a sister. Leaving Pinkie’s room Maud returned to her own, upon passing her parent’s room she heard stirring from within.
