A Great Many Pies

“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!”
