Pinkie Cream Pie
It always hurt Pinkie a little to travel on the train alone, as it was really hard to get random ponies to share in her own excitement as she usually would with her friends. It was even harder when there were so few on board; not many ponies traveled out to the rock fields for any reason, let alone a vacation. Pinkie was pretty sure that even the train's conductor didn't want to be going there, though it was a little difficult to get a straight answer while he insisted that she leave his train car.
Pinkie was jarred from her thoughts with a sudden jolt, the train's abrupt stop nearly flinging her out of her seat.
"Last stop, Rambling Rock Ridge. Please grab all of your belongings and exit the train car in an orderly manner"
Upon hearing the conductor's call, Pinkie sprang from her suspended position and sped out of the train door. She swiftly darted around the station's singular platform, her eyes fixating on a singular pony waiting under the station's light.
"LIMESTONE!" she shouted as she bowled over her sister and squeezed her in a tight embrace.
"Ack! Pinkie, how many times do I have to tell you not to do that!" Limestone grunted as she pushed Pinkie off of her, the young party pony caving easily to her formidable strength. She stood and dusted off her stone gray shirt and dark jeans before Pinkie resumed her clinging.
"I'm sorry, I just missed you so much! Where are the other two?"
"Don't worry, Maud's just catching up, you know how... wait, other two?" Limestone wondered as she looked around herself. "Oh, for the love of... MARBLE! Pinkie's the only one here, get your butt out here!"
Pinkie turned to see her younger(?) sister's head peek out from behind the station's singular wall, quickly confirming that the party pony was indeed the only passenger before stepping out onto the platform. Her more bountiful physique was concealed underneath a dulled forest green sweater and jeans that matched her elder sister's.
"MARBLE!" Pinkie cried as she repeated her greeting to Limestone, the only rebuttal being a small squeak as Marble fell to the station's floor under the weight of Pinkie's embrace. Her bear hug was cut short as Limestone grabbed Pinkie by the collar of her shirt and lifted her away from Marble. "Hey!"
"You gotta stop doing that."
Both Limestone and Pinkie turned to see Maud approach the platform, her denim blue dress swaying softly in the breeze. "MAUD!" Pinkie exclaimed as she attempted her signature greeting once more, only to be stopped by Limestone's hand still on the collar of her shirt.
"Let's get Ms. Sugar Rush back home, shall we?"
"I tell ya, things have gotten reeeeally crazy back home," Pinkie told her sisters, recounting her recent adventures as they made their way back to the rock farm. She decided to leave out her recent experience with Twilight; she had a different idea in mind for when she divulged that story.
"Can't say you don't live a wild life out there, sis," Limestone responded as she and Marble did their best to out together what Pinkie had been trying to explain. "So your best friend's a princess now? Can't say I ever thought you'd get along with royalty, but I guess you're always full of surprises."
"Oh, she's super duper amazing, even before she was a princess. I'd love for you guys to meet her, and the rest of my friends. Which brings me to why I'm here," Pinkie started as she raced ahead to their doorstep and rummaged through her bags pulling out a large banner and planting it over her head. "I'd like to officially invite you to come stay with me in Ponyville!" she excitedly announced before adding "For a few days, of course. Unless you wanna come live there in which case *Mmrph*"
Maud covered her sister's mouth before she continued on her tangent. "You just got here, why are you inviting us to come visit you somewhere else?" she asked as she pulled her hand back to let Pinkie answer.
"Well I didn't mean right now! I meant when I go back home." Pinkie retorted. "Don't get me wrong, I love coming back home to see you guys, but.." she paused as she looked around, "It would be nice to spend time with you someplace where there's, you know, a little more excitement... and color."
Pinkie looked to each of her sisters as they muttered their agreement. "So whaddya say? Wanna come back to Ponyville with me for a little while?"
Pinkie's attention shifted to Limestone first, the older sister walking past to enter their homestead. "Look, Pinkie, I'd love to come and see your home, but Mom and Dad are out at the trade center with our haul, and they won't be back for a few weeks," she explained, the others following her inside. "Someone's gotta run the farm while they're gone."
Pinkie turned her attention to her other two sisters, giving them a pleading expression as she pouted her lip. Marble shook her head, silently explaining that she was obligated to take care of the home while their parents were away. Pinkie's pouting intensified as she slid right up to her last option.
"....Ok," Maud stated in her monotone voice.
Pinkie exploded with glee as she bounced off the walls shouting "YES YES YES YES YES YES YES YES!!!!", her sisters barely able to keep their eyes on her. Maud eventually held out her hands to catch her sister as she nearly flung past, stopping her dead in her tracks.
"We can worry about that later. How about we enjoy your stay here first?"
"Ooo, OK! What did you have in mind?" Pinkie inquired as she popped out of Maud's hands with little effort.
"You know, since Mom and Dad aren't here, we could finally *ahem* treat ourselves," Limestone suggested as she cupped her hand underneath Pinkie's generous chest, earning a large smile from her younger sister.
"Oh, could we please?! It's been so, so, SO long since I've had you girls in bed with me," Pinkie begged to her other siblings, each of them responding with a nod and a soft smile as they approached her.
Pinkie's three sisters quickly set about undressing her, feeling up every inch of her body as they pulled the fabric away. Marble huddled against her back and reached up to fondle Pinkie's breasts, pinching and squeezing her nipples until they were hard as diamond. Maud kept to Pinkie's side, kissing her sister and letting her hands roam up and down the pink pony's midsection. Limestone knelt down between Pinkie's legs, wasting no time to press her tongue between Pinkie's thighs and start lapping at her lips.
Pinkie practically melted under all of her siblings' attention. She absolutely loved when they took full advantage of her to fulfill their desires, and they sure did take advantage of her. The three of them pushed Pinkie down on her hands and knees, Maud moving in front of her and forcing the large pink mane before her down to eat her out, to which Pinkie happily obliged.
Limestone continued her own aggressive licking, adding her hands to spread Pinkie's lips open and push two of her fingers inside with her tongue. She didn't worry about how much Pinkie could handle; her sister had proven time and again that they could get away with just about anything and she would be totally fine.
Marble laid on top of Pinkie's back, holding her sister in a tight embrace as she groped Pinkie's massive tits and ground her entire body against her back. She could never explain why, but Marble always loved being either directly on top of her sister or holding her very close.
"I think she's ready girls," Limestone chimed as she stepped away from Pinkie and over to a small box that sat underneath her bed. "What do you say, Marble? Do you wanna move on to our favorite part?"
"*HUFF huff* Uh- Uh-huh," Marble panted as her grinding intensified, her hands squeezing Pinkie's boobs with as much might as she could muster.
Limestone pulled from the box three strap-on dildos, each with a sizable nub on the other end to help pleasure the wearer. Two of them were a dark gray made of the smoothest stone her and Maud could find. The third was a shiny violet, made from what appeared to be some kind of gemstone or similar material.
Limestone tossed the purple one towards Maud, the toy landing beside her thigh. Limestone then took one of the other two and lined it up with Pinkie's soaked pussy.
"Here, let me just get it lubed up for you first," she explained as she shoved the toy as far into Pinkie's snatch as it could reach, earning a loud but muffled cry from the party pony. Limestone thrust it back and forth a few times before removing it and securing it around Marble's waist. "Let's see just how much she gushes this time," Limestone teased as she helped Marble line the toy up with Pinkie's anus, pushing the tip in before letting Marble handle the rest.
As soon as Marble felt the tip of the toy rest inside Pinkie, she thrust the rest inside and began furiously fucking Pinkie's ass, her grip somehow tightening even more as she feigned milking her sister's tits. The sudden burst of pleasure always caught Pinkie off guard, even when she had come to memorize her sisters' routine. She felt like every nerve in her body was on fire, and she knew that her siblings weren't even half done with her yet.
Pinkie's screams of delight fed directly into Maud's own excitement, each moan and cry bringing the monotone mare closer and closer to her own climax. She wanted to strap on her own toy, but it never did as good of a job of satisfying her as Pinkie's mouth did. That's why she always let Pinkie finish her off and get her drink before she even touched the dildo.
It was also wise for her to swap over last, as she easily got the greatest benefit from her sisters railing Pinkie's other two holes.
Limestone watched as Marble had her way with Pinkie, causing the pink pony's pussy to splatter her fluids with every thrust Marble made. "Mmm, she's been waiting for this for a while, she spraying so much!" Limestone teased as she slipped her own strap-on around her hips. "Guess it's about time we cork that fountain."
Just as before, Limestone wasted no time in shoving directly to the end of Pinkie's canal, pushing the party pony even harder against Maud. The older sister almost doubled over from the sharp spike in pleasure as the vibrations from Pinkie's ecstatic screams echoed throughout every nerve in her body. She began rubbing her swollen lips harder against Pinkie's muzzle, timing her thrusts against Limestone and Marble's to ensure that Pinkie was being shove as deep into her vagina as she possible could.
One final push sent Maud over her limit as she grunted and sprayed her fluids straight down Pinkie's throat. Pinkie eagerly lapped up as much as she could, but what Maud lacked in vocalizing her excitement she made up for in spades with how much she ejaculated; it was always a challenge for Pinkie to collect it all. It didn't help that Maud's taste threw her libido into overdrive: screaming in ecstasy made swallowing quite difficult.
It wasn't much longer until Maud's climax died down and she removed herself from Pinkie's lips to affix her new toy to her hips. After securing the shiny toy to her waist, she reintroduced her pelvic region to Pinkie's muzzle.
"Ooh, getting a little fancy, are we? Didn't think you liked gemstones this *glurk*!" Pinkie was cut off as Maud shoved her toy into Pinkie's mouth, gently ensuring that she didn't hurt the pink pony before she matched her sisters' thrusts.
"It's not gemstone," Maud explained between her movements. "It's rock candy."
That sentence alone drove Pinkie to suck harder than she ever had. Knowing Maud's penchant for crafting the crystalline sweets, she didn't have to worry about sucking the toy away completely for hours. Maud was reaping the benefits of her new toy as well, as Pinkie's enthusiasm meant the nub in her own pussy was being rocked in every possible direction, and quite vigorously too.
This was Pinkie's favorite part. Having all three of her sisters abusing her holes for their own pleasure. It never mattered how many times Pinkie came during these sessions; she always came a lot, but the fun didn't stop until her sisters had each gotten their fill. And if there was one thing that all Pies had in common, it was endurance.
Pinkie lost track of how long she had been pinned to the floor, her mind too preoccupied with her sisters' attempts to get her off even more. She was nothing more than a colorful array of buttons, and they were determined to press each and every one of them. Marble would tweak Pinkie's nipples and push them back into her breast, sometimes attempting to squeeze her finger inside the small nub. Maud took full control of Pinkie's head, twisting and angling it so her dildo reached every unexplored inch of Pinkie's throat. Limestone thrust her fingers alongside either her own dildo or Marble's, curious to see just how much her younger sister could take.
Pinkie's own orgasms had become a blur, her pussy constantly squirting around Limestone's toy and saturating the older sister's legs with her juices. The sheer wetness on her thighs was enough to finally push Limestone over the edge, her own earth-shattering orgasm joining the puddle that sat beneath her legs. Marble's own climax soon followed, spraying between Pinkie's ass and Limestone's pelvis. Maud held on for a little longer before she let her own orgasm take her, holding Pinkie as far down her dildo as she could.
Pinkie's only regret was that they couldn't fill her up like Twilight did.
As each of the three sisters recovered from their finishes, they removed themselves from Pinkie, leaving her to release a few more spurts of her on cum before she lifted herself from the floor. "You girls are the best. I love you so much."
Maud gently lifted her sister's chin. "We love you to sis, and we're not done showing you how much."
"Yeah, I still gotta get a turn at that ass," Limestone chimed in as she joined the other two to swap toys. All three then stood over Pinkie, gently lifting her and turning her onto her back.
"So, ready for round two?"
