A Great Many Pies

“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?”
