A Great Many Pies

“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.
