Waking up Pinkie found herself pressing into Limestones back, her cock buried deep in her sisters sex. Thinking it must have accidentally happened while asleep she started pulling out, but when a flow of cum followed behind her she knew something more must have happened. Afraid she had done something awful in the night she looked up at Limestone ready to see a tear stained face or some sign of unhappiness, but instead saw her resting peacefully, a smile on her face. Deciding that if she was smiling nothing bad must have happened, Pinkie got out of bed and headed towards the bathroom to start the day

Walking in the room she heard the shower running, and without asking, quietly jumped in and hugged whoever it was from behind. Digging her already hardening cock into their butt Pinkie said to them, “Good morning!”

“Oh, good morning Pinkie.” Maud said rubbing soap on her body, not reacting to the dick rubbing against her ass.

“Morning Maud, want me to help you wash?” Pinkie asked, already sliding her hands down and groping her sisters prodigous rear.

“No thanks, I don’t need help,” Maud said causing Pinkie to stop.

“You can fuck my ass if you want though.” the mare said while nonchalantly going back to her cleaning.

Pinkies cock jerked as she started rubbing her sister again, “your so deadpan you even catch me off guard sometimes.” Pinkie said while pulling apart Mauds cheeks to expose her pronounced hole. Shoving two fingers in she found Mauds puffy ponut was already well lubricated, from cleaning or having some fun earlier Pinkie didn't know, but it did make her job easier. Starting to finger her sisters delicious hole Pinkies cock went rock hard, from feeling her digits thrust in and out of her sisters ass. Pulling out her fingers she grabbed onto her cock and started lining it up with her puffy hole, the tip pushing against it, testng its give. Pushing the head in she found less resistance than she thought she would, her cock sliding easily into her still washing sister. Only once she was able to push half her length in did she start to feel resistance, then pulling back started to thrust.

Curious about her sisters sudden flexibility Pinkie asked,“ hey Maud you're taking a lot more of me today. Have you been doing anything to your ass?”

Looking back at her, not reacting to her sisters thrusts, “Yes pinkie,I’ve been trying to stretch my butt. Hopefully soon I’ll be able to take all of your cock in me.”

Gripping her sisters sides Pinkie felt herself stiffen further, “wow that’s great Maud. So what have you been doing?”

“I’ve started walking around with a dildo in my ass,” She replied soaping up her tits.

“You're walking around with stuff up your butt all day?” Pinkie asked surprised.

“Yes, is that a problem?” She said in her monotone voice.

“No but it sure is hot sounding!” Pinkie replied, starting to thrust faster.

“Is it? I simply find the sensation pleasurable.” Maud’’s voice was starting to distort a bit from how fast and hard Pinkie was thrusting into her.

Thinking for a second Pinkie said. “Hey since you like putting stuff up your butt then why don't we help each other out!”

“How so?” Maud replied, having now braced herself against the wall.

“Why don’t I help you train your ass, since you like it so much.” Pinkie now hunkered over trying to get her shaft further in.

“That sounds agreeable” Maud said, he ponut spread by her sisters member.

Slowing down her thrusts Pinkie let Maud get back to washing and started talking about their day. Without much interruption besides Maud having to bend over and pick up the soap more than a few times. They talked about different things, what they were going to do, ow they thought the weather was going to be, and how Maud liked Ponyville. Finally Pinkie felt herself getting close and buried herself deep in Mauds ass, shooting rope after rope of her thick futa cum in her ass. Finally once Pinkies flow stopped she was about to pull out, but was stopped by Maud.

“Wait Pinkie, do me a favor and grab that. She said pointing out of the shower.

Reaching out Pinkie pulled back a sizeable plug, almost as wide around as her own cock. Pulling her cock out she quickly plugged Maud’s ass, sealing her cum inside. Maud’s puckered ponut creating a tight seal around the toy. Both sisters finished cleaning each other off and made their way to breakfast.

Pinkie cooked up an nice breakfast for the four of them and they ate quickly. Then watching Limestone clean up, Pinkie fely happy and proud her sister didn't try and talk back or start a fight this time. When she finished Pinkie decided to talk to her about it.

“Alright Limey since you were good today I’m gonna give you a reward, any idea what do you want?” Pinkie asked cheerfully.

“I don't want anything from you,” She said sounding grumpy.

“Aw come on don’t be like that, I’m trying to be nice.” Pinkie said starting to lose her smile.

Obviously getting mad Limestone replied,” This whole thing is stupid, sleeping in your bed is stupid, cleaning the dishes is stupid.” The quietly at the end she added, “Your tasty cock is stupid.”

Starting to frown Pinkie said to her, “Limestone you were acting so good and now you're being mean again. If you keep doing this then I’m going to show you some humility.”

“Pft, you're not brave enough to punish me.” Limestones sex started moistining at the mention of punishment, “ and even if you could you’re too scared to do it around Marble and Maud.”

“Fine, if you want me to prove I can be tough I will,” Pinkie said grabbing Limestones arm and dragged her to the living room.

Inside Maud and Marble were sitting around relaxing in a pair of armchairs talking. When Pinkie dragged Limestone in though they both stopped and started staring, wondering what was going on.

Limestone was dragged to the center of the room with the two chairs with her sisters in front, and a couch behind.

Pinkie started addressing both her sisters. “Limestone here needs a lesson in humility, her continuous bad behaviour leaves me no choice but to take drastic measures.” Pointing at Limestone Pinkie said in a commanding voice, “Limestone strip nude now.”

A defiant look in her eye Limestone replied, “make me.”

Pinkie responded by grabbing the smaller mare and staring into her eyes, then replied. “You will even if I have to do it myself.

Limestone feeling her pussy moisten further started to comply, stripping naked as her three sisters watched her.

Once she was done Pinkie walked away and sat on the couch. Pulling her skirt up she exposed her flaccid dick.

Pointing down at her flaccid member she said, “now get over here and make me hard.”

Limestone started taking a step towards her, but Pinkie made her stop.

“Did I say you could walk? Get down on your knees and crawl over here.”

Looking back at her two sisters, Limestone knew they would see her moist pussy. Giving a shudder she dripped on the floor, Pinkie was really turning her on. Slowly getting down on her hands and knees she heard Marble give an audible gasp, probably already noticing her wetness. Starting her crawl forward her pussy lips rubbed against each other, further arousing her. Slowly she crawled across the room, feeling her slit drip a few more times till she finally came face to face with Pinkies limp shaft. Staring at the member for a few seconds Pinkie put a hand on her head, and she was suddenly forced into her crotch, nose pressed against Pinkies balls..

Holding her sisters head Pinkie said, “Get a good smell of my crotch, you’re gonna be getting to know it a lot better.”

Breathing in deep Limestone took in her sisters scent, the thick musk filling her senses and making her mouth water. Opening her lips she started started licking the prodigous balls in front of her, their salty flavor tasting amazing. With Pinkie’s hold loosening she started moving towards her shaft, the length already starting to swell. Finally reaching it she worked her way to the tip licking and giving it kisses, her sisters musk starting to overwhelm her. Reaching the tip she opened her mouth, and breathing heavy, took the head in her mouth. Swirling her tongue over the head she picked up some of her sisters salty pre, quickly cleaning it off her delicious cock.

Watching Limestone service her Pinkie had an idea, calling out to her sister she asked, “Marble did Limestone ever apologise for yelling at you in the shower?”

“N-not really,” the shy mare responded.

“Well why don't you give her a little pay her back then? Come over here,” Pinkie said gesturing her over.

Marble made her way over to them, Limestone was starting to take some of Pinkies cock in her throat. Quietly she asked, “What do you want me to do?”

“Give her a spanking, that seems like a good punishment.” Pinkie said grinning, her cock twitching in Limestones mouth.

“Um, if you say so.” Marble said, somewhat concerned..

Positioning herself behind Limestone, Marble looked at her dripping pussy. Obviously she didn’t see this so much as punishment since she was absolutely soaked. Reaching back her hand, she brought it down on Limestones rump with a sharp slap. The mare made a moaning noise through Pinkies cock and arched her back. Quickly though she went back to sucking on Pinkie, seemingly with more gusto as she took more of the shaft in her throat. Reaching back again she gave Limestone another solid smack, this time feeling her hand glance her ponut. Starting a rhythm, Marble continued to spank her sisters ass. Her behind jiggling and bouncing with every strike.

Meanwhile Limestone kept working pinkies stallionhood, the thick rod now halfway down her throat. Moaning around the shaft she kept trying to work more of the member in, her sisters thickness starting to make it hard to breath. Grabbing onto the pink mares ass she started trying to force the cock down her throat, trying her best to deepthroat as much as possible. Coming up for air finally she caught her breath, she had almost reached the base and just needed to go a few more inches. Pushing back down she found Pinkies hand on her head again, and that she couldn’t pull up. Being forced down her sisters shaft her throat started to squeeze and clench the length. Her air started running out when she finally reached her sisters base, eyes rolling up in her head she started cumming after another slap from Marble glanced her pussy. Clenching tight Limestone rode out her orgasm, the entire situation she was in pushing her even further than normal.

Finally finishing she was pulled off the shaft where she found an unhappy looking Pinkie.

“Did I say you could cum?” Pinkie asked glaring at her. “This is supposed to be a punishment, your not supposed to have fun. you're in big trouble now.” Pinkie said to the the panting Limestone, the mares face had tears running down it from lack of oxygen, and pussy still clenching.

Starting to grin Pinkie called out to Maud, “Hey Maud, how would you like to have Limestone eat you out?”

“Sure Pinkie that sounds fun.” Maud said getting up.

“Have my spot and pull up your dress,.” Pinkie said getting off the couch.

Walking over Maud got on her knees, and laid her front half on the couch. Then reaching back she pulled the her dress over her ass, exposing her plugged ponut from earlier. Reaching Pinkie pulled the plug out with a pop, and a rivulet of cum rolled down her ass.

“Well it’s a good thing me and Maud had fun earlier, looks like you even get to have a snack.” Pinkie said with an evil grin.

Crawling over to Maud's leaking ponut she gave it a look over and took an exploratory taste, gathering some of Pinkies cum on her tongue and swallowing.

Looking angry Pinkie said” I said eat her, not lick her.” Grabbing onto Limestones head she shoved the other mare between Maud’s sizeable cheeks, her mouth opening in sock and engulfing her sisters ponut. “Now I better see some tongue action.”

Sticking her tongue inside Mauds ass she started licking Pinkies cum out, eating her sisters ass like a slut. Limestones pussy was continuously tingling, reveling in the debauchery her sister was making her go though. She was beyond glad she had pushed Pinkie earlier.

Pinkie positioned herself behind Limestone and said, “Don’t you stop till she cums.” Grabbing onto her dick and pressing it against Limestones ass she added, “I hope your ready for your own cream filling.” Then started pressing into her sisters ponut, forcing her sizable head in her sisters ass.

Limestone moaned into Mauds ass, continuing her work as Pinkie started to ravage hers.

“That’s right bitch, your ass is mine to do with as I please.” Pinkie gasped out, giving Limestones butt a slap. “Eating your sisters ass and getting railed by another, Celestia your even moaning! I bet you love this don’t you, big tough Limestone being a bottom bitch. Well don’t worry lovely sister of mine, we’ll take care of you.” She gave her ass another slap, “Even Marble is getting off to watching you get dommed.”

Limestone looked over and saw Marble in her chair, biting her lower lip and fingering her cunt while watching the spectacle.

Feeling Pinkie start to thrust faster Limestone started pushing herself back against her, trying to get as much of her cock in her as possible. Faster and faster Pinkie fucked, not able to fully embed herself in her sister. Finally with a loud grunt Pinkie leaned forward and pressed Limestones head into Mauds ass hard. With a few more violent thrusts she shoved her cock as deep as possible and unloaded her cum.

Limestone shoved her tongue deep into Maud’s ass, and felt something wet splash against her chin before she started riding her own orgasm. Moaning into Mauds ass while her pussy clenched, and ass was filled with cum.

“There” Pinkie said when she was finished, pulling her cum covered cock out of Limestones ass. “Also don’t think I didn't notice you came again without permission, because of that you aren’t allowed to wear clothes for the rest of the day.” With that Pinkie grabbed up Limestones clothes and went to hide them away in her room, leaving Limestone on the floor in a puddle of her own fluids and Pinkies cum.

Looking around Limestone saw Marble coming down from her own orgasm, and Maud busy plugging her ass. Taking a moment to breath she thought about how exciting all this had been.

Author's Note

So this trash fire isn't dead yet. Without rereading them, I know the older parts of this are probably just pure garbo. When going to edit this after not touching it for 6 months I ended up rewriting the whole thing, so that should say something.

As usual point out any problems and thanks for reading.
