Sweetie Belle burst through the door of Carousal Boutique and threw her bag carelessly to the side as she rushed inside. “Rarityyyyyy!”
The mare working at the sewing machine in the room sighed, but didn’t stop her work or turn to face her sister. “Hello Sweetie Belle. Did you have a fine day at school?”
“It was alright. More importantly…” Sweetie Belle pressed herself against her sister’s leg and gave it a light nuzzle. “You wanna play? Mum and Dad won’t be home ‘til late tonight so we have some time.”
“Sorry, Sweetie Belle, but I’m far too bust at the moment. I have to complete this order by the end of the week.”
Sweetie Belle pouted as she looked up at her sister. “But-”
“I’m afraid you will just have to be patient,” Rarity said with finality, causing her sister to turn around with a huff.
Moments later a knocking at the door drew Rarity’s attention to a familiar stallion and his daughter. “Good afternoon, Rarity,” Filthy Rich said with a smile.
“Oh, Mr. Rich. Please, do come in. I’ll prepare some tea.”
“No need,” Filthy Rich said as he walked inside with his daughter. “I actually have to run off right away. I’ve been called into work rather suddenly and I need somepony to watch Diamond. She’s grounded and so I can’t very well leave her home alone, and though it is rather sudden I was hoping that you would be able to-”
“Of course I can watch Diamond for you,” Rarity said, waving at the little filly. “You know I’m always happy to sit for you.”
“You’re a lifesaver.” Filthy Rich kneeled to his daughter. “Daddy’s heading off now. Be good for Rarity and do as she says.”
“I will,” Diamond said, giving Rarity a mischievous grin that went unnoticed by her father. Filthy Rich hugged his daughter and then left the store. As soon as the door was closed Diamond turned to Rarity and asked, “So, what games are we going to play, Miss Rarity?”
Rarity knew what Diamond Tiara was getting at but had no desire to play along at that time. “Sorry, Diamond Tiara, but none of that today,” she said, confusing the filly.
“She’s ‘too busy’,” Sweetie Belle explained, rolling her eyes.
“Too busy for me?” Diamond asked, genuinely surprised.
“I’m afraid so,” Rarity said as she returned to her sewing.
Diamond Tiara huffed and walked away, before an idea came to her mind. She faced Sweetie Belle, who apparently had the same idea as the two shared an evil, scheming grin together. “Well then,” Diamond said, “I’ll just have to find somepony else to play with.”
“I’m free,” Sweetie Belle said as she approached Diamond and leaned forward, puckering her lips for the pink filly.
Diamond Tiara stole a kiss from Sweetie Belle, wasting no time in prying the white lips open with her tongue and tasting the prize waiting for her inside. Sweetie Belle moaned into Diamond’s mouth, causing the pink filly to press even harder.
Rarity frowned as she watched the two in her mirror for a moment, before returning to her work, ignoring the two fillies making out behind her as best she could. Which didn’t last long as a squeak from Sweetie Belle caught her attention again, and she looked back into the mirror to find Diamond Tiara nibbling her sister’s ear.
“Diamond, nooooo…”
“I missed lunch today,” Diamond said, “And I’m in the mood for some sweet marshmallow.” She reached over and gripped Sweetie Belle’s flanks, licking her lips as she gave them a good squeeze.
“You’re so naughty,” Sweetie Belle giggled. “No wonder you’re grounded.”
“Yeah, I’m a mean filly,” Diamond Tiara said as she gave the tip of Sweetie Belle’s horn a lick, before gently pushing Sweetie Belle down onto her back and climbing on top of her, “And I’m gonna enjoy picking on you, blank flank.”
Rarity’s patience was reaching its limits. She watched Diamond Tiara going to town on her sister’s neck whilst her hoof slowly inched down towards Sweetie Belle’s most sacred zone. “Girls, please.”
“Don’t mind us, Miss Rarity,” Diamond Tiara said as she finally made contact with Sweetie Belle’s moist lips, eliciting a sharp moan from the filly trapped helplessly beneath her. “We’re just playing a game. You go ahead and work on those dresses.”
Rarity’s eye twitched as she watched Sweetie Belle squirm about under Diamond’s touch, her face the very picture of ecstasy as lewd moans and gasps filled the room. “Girls,” Rarity repeated, only for Sweetie Belle to wrap her hooves around Diamond Tiara’s neck and bring the bully down for another kiss. “Girls, stop it, I-” Diamond Tiara snapped the final straw as she purposely pointed her own rear end towards Rarity’s mirror, flagging her tail into the air and revealing her own fillyhood, glistening and winking as it practically begged for attention. “Alright!”
Diamond stopped and pulled back, sharing a victorious grin with Sweetie Belle. “Alright?” she asked, seeking clarification.
“Just… go and wait for me upstairs. I will be up after I lock the store.” Rarity turned around and gave the two a stern look. “But only one round!” she added, receiving nods from the smiling fillies as they slowly climbed to their hooves and then took off together up the stairs. With a sigh, the older mare used her magic to lock her front door and plant a ‘closed’ sign on the window, to ensure that there would be no interruptions. She spared a final guilty glance at the dresses she was abandoning before making her way towards the stairs. ‘Oh my sweet, sweet sister and my dear Diamond, why can I not quit you?’
As Rarity ascended the stairs, she heard noises coming from her bedroom. Grunts and moans from two little fillies, and the sound of springs in a mattress moving up-and-down. Rarity picked up the pace and reached her bedroom door, pushing it open just in time to find her sister, underneath Diamond Tiara once more, arching her back and screaming at the top of her lungs, with Diamond not too far behind.
Rarity approached the bed as the two fillies collapsed, both breathing heavily, completely unaware of her presence until her magic removed the long, purple object between their legs that was connecting the two fillies together.
“AH!” Diamond quickly turned her head to find Rarity grinning at her.
“Did I not tell the two of you to wait for me?”
Sweetie Belle gave a nervous laugh as she inched her way out from underneath Diamond. “Sorry, Rarity. We were just too worked up from before to wait any longer…”
“It’s your fault,” Diamond Tiara stated in a defiant tone. “You should have just played with us from the start.”
“Oh? I suppose you’re right.” Rarity used her magic to lift Diamond Tiara into the air, spun her around and then planted her down onto her back. “In fact, since you want to play so much, I think we should start with you. I’ll make up for neglecting you for so long.”
Diamond Tiara tried to free herself, but found it to be a useless endeavour. Instead, she resorted to her next tactic: smiling innocently and pleading for mercy. “Um, you know I was just joking, right?”
“Too late, dear. You wanted my attention and now you’re going to get it. Sweetie Belle, please hold her still for me.”
“You got it!” Sweetie Belle chimed with a salute. She crawled over to Diamond Tiara and held the other filly’s forelegs to keep her steady. “Sorry Diamond! She’s my sister and all.”
“You little traitor!” Diamond yelled as she struggled against Sweetie Belle’s hold.
“Now, now, do relax, darling,” Rarity said, lowering herself to Diamond Tiara’s flower and taking a good whiff of demanding fillyhood. Rarity licked her lips. “I’ll be gentle.”
When Rarity’s tongue made contact, Diamond Tiara gasped and would have jolted upright, had Sweetie Belle not been doing a good job of holding her down. Sweetie Belle looked down on Diamond’s face with a loving smile. “You’re so cute,” she whispered into Diamond Tiara’s ear, though the other filly seemed to be experiencing too much pleasure to have heard her. Sweetie Belle couldn’t resist leaning forward and kissing Diamond, enjoying her upper mouth whilst Rarity feasted on her lower one.
Rarity moved her eyes up and smiled at the sight of her little sister and her little… friend, getting along so well, but she felt bad leaving Sweetie Belle out and focussing only on Diamond. Her hooves weren’t exactly doing anything, so she decided to put them to good use… on Sweetie Belle’s horn.
Sweetie Belle’s eyes almost bulged out of their sockets as a sudden shock rushed through her horn, spreading throughout her entire body. “AAAAHHHHH!” Sweetie Belle collapsed beside Diamond Tiara and writhed helplessly as her sister’s hoof moved up-and-down her horn very quickly.
Meanwhile, Diamond Tiara was drawing close and the only thing her mind could focus on the wave of pleasure that was building up inside of her, inching closer and closer to its release. One final flick of Rarity’s tongue over her little pink nub pushed Diamond over the edge and she cried out in delight as she filled Rarity’s mouth with the hot filly juice she had been craving.
Satisfied with her work, Rarity licked her lips to take in the full taste of Diamond Tiara before focussing all of her attention on Sweetie Belle’s horn, stroking faster and delighting in every last erotic sound that came from her sister’s lips. The first sparks of green light came from the tip of the horn, alerting Rarity that she was getting close.
“R-R-R-Rarrrrityyyyyyy…” Sweetie Belle kicked her little hind leg and spasmed on the bed as more sparks shot forth from her horn. An explosion of green magic accompanied her ear-piercing scream and Rarity continued to stroke until every last spark was out of that horn.
Looking down on the two heaving, exhausted fillies, Rarity could only chuckle as she admired a job well done. “Well now, it seems that the two of you really enjoyed that.” Diamond Tiara slowly sat up and nodded her head. “I believe it is now my turn, though.”
Sweetie Belle suddenly recovered and quickly bolted up. Her sister leaned back and spread her legs, revealing herself to her two little lovers. “I’ll do my best!” Sweetie Belle cheered as she dove in, only to be pushed back by Rarity’s hoof. Sweetie Belle whimpered at being denied her treat.
“Now, now, Sweetie Belle, what have I taught you about sharing?”
“Yeah,” Diamond said smugly, “You gotta share, Sweetie Belle.”
“Hmph! Fiiiine,” Sweetie Belle conceded. With an approving smile, Rarity removed her hoof and allowed the two fillies to get to work. Sweetie Belle moved in quickly, determined to get the first taste. Her little, inexperienced tongue sent shivers down her sister’s spine, and it wasn’t long before she felt Diamond Tiara invading her territory.
The two fillies would occasionally bump heads, or wind up fighting over territory, but eventually they both found a compromise that seemed to work for them. Still, Sweetie Belle wanted to do more than simply being ‘the other filly’. She wanted to do something unique, something that wasn’t just a copy of what Diamond Tiara was doing.
Her eyes fell on the area just above Rarity’s folds. Two perk breasts were sitting right before her eyes, erect nipples sticking high into the air, giving out an enticing smell that drew the filly in.
Rarity gasped in surprise at the sudden attention to her teats. She certainly hadn’t expected that. Sweetie Belle started going to town on her Rarity’s nipples all on her own, suckling and occasionally nibbling lightly, greatly increasing the pleasure that Rarity was experiencing. It didn’t take long with that relentless double-assault for Rarity to reach climax, and Sweetie Belle quickly moved back into position in order to catch as much of her sister’s juices as she could.
Both Diamond Tiara and Sweetie Belle giggled as they saw each other’s faces, completely drenched in the product of Rarity’s orgasm. Sweetie Belle, the ever-considerate filly that she is, leaned forward to lick some of the mess from Diamond Tiara’s face. Diamond Tiara returned the favour, and it didn’t take long before those tongues of theirs shifted from each other’s cheeks to each other’s mouths.
Rarity, meanwhile, had taken the time that the two fillies were enjoying each other to recover from her high. “My goodness. That was… simply wonderful…” Stretching her forehooves into the air, Rarity turned to face the clock on her bedside. “But I’m afraid I must be getting back to work. I did only say ‘one round’, after all.”
This caught the fillies’ attentions, as they both stopped kissing and exchanged nods to each other. “One second, Miss Rarity,” Diamond Tiara said as Sweetie Belle reached under the bed sheets. “We have something to show.”
“Oh? What?”
Diamond Tiara grinned. “This… NOW!”
Sweetie Belle pulled out two toys from beneath the sheets. Phallic devices designed to be worn by mares to simulate the having of a penis. In other words: two strap-ons.
Meanwhile, Diamond tackled the older mare and pinned her to the ground with her unnatural filly strength. Rarity, caught by surprise, couldn’t react before Sweetie Belle gave one of the toys to Diamond Tiara and equipped the other one onto herself, moaning as her own end entered her dripping hole.
“W-What is the meaning of this?!” Rarity demanded as she watched Diamond insert her toy into herself and ensure that it wasn’t going to come off. “I told you, I have work to do!”
“We know,” Sweetie Belle said. “But surely you can stay for one more round. We just want to show how much we love you.”
Rarity felt her heart melt. She hated when Sweetie Belle played the love card. “E-Even so-”
“Relax,” Diamond said as she positioned herself at Rarity’s entrance. “We’ll make you feel better than ever.”
Rarity glanced at Sweetie Belle as she heard the sound of a cap popping off of a bottle. She found the filly applying some lubricant to her plastic shaft and gasped as she felt something entering her marehood. Diamond Tiara suddenly penetrating her distracted Rarity long enough for Sweetie Belle to finish her preparations and assault Rarity from behind… in her behind.
“Ah-AH-AAAAAAHHHHH!” Rarity’s cries filled the rooms as the two fillies entered as deep as they could from either side, each stopping to get used to the intense feelings they were experiencing on their own ends. Rarity was speechless. She had never expected the two to do anything like this of their own accord, but she had to admit, Diamond was right: this was unlike anything she had ever felt before. Especially when they began to move again.
The fillies seemed to lack any sort of rhythm or pattern, instead just thrusting in-and-out at their own paces, pulling out a different amount each time and thrusting with varying strengths. All that Rarity could do was sit there and allow herself to be taken by the two horny fillies she had clearly trained too well, not caring for the drool leaving her mouth or the incoherent babbling that escaped her lips.
To her surprise, her sister had managed to come before she did, suddenly stopping with her toy buried deep inside Rarity’s back entrance and shuddering as she clung to Rarity’s back. Diamond Tiara didn’t seem to be far behind, and Rarity doubted she could hang on much longer either. “S-Sweetie B-Belle, dear… p-please, I’m almooooost there… Please don’t s-s-stop now…”
“B-But I can’t… go anymore…”
Rarity whimpered, but she wouldn’t give in. She was close, but she didn’t know if Diamond could keep it up long enough for her to reach the end. Desperate to reach climax before Diamond did, Rarity grabbed one of Sweetie Belle’s hooves that was wrapped around her waist and brought it down, rubbing it against the little bump above her entrance.
The room filled with the cries of three ponies reaching orgasm together and Rarity’s mind went blank. All that she could see was white, and all that she could hear was her own huffing and heaving. Eventually she felt something. Her sister must have recovered first, because she felt her sister’s phallus leaving her back hole. When Rarity finally regained her senses and could comprehend what was happening around her, she could see that Diamond Tiara had fallen asleep whilst still buried deep within the older mare.
Turning her head to look behind herself, Rarity found that Sweetie Belle was also fast asleep, a wide, satisfied smile on her face. Rarity smiled too. “Thank you, girls,” she whispered as she gently brought Sweetie Belle over with her magic, placing her beneath the covers of her bed to one side. She pulled herself off of the toy still strapped to Diamond Tiara, giving a light moan in the process, and blushed at the large stain left on her bed. Clearly there was some laundry duty for the fillies later.
But for the time being, Rarity would allow them to rest. She took the toys and placed them to one side, too tired to bother placing them back into their proper drawers. She ten tucked Diamond Tiara into the bed on the opposite side to Sweetie Belle, and climbed in herself, settling herself down in-between the two of them. “Work can wait… For now, I need some shuteye.”
Rarity kissed the two fillies’ foreheads and felt both snuggle up closely. “Sleep well, my sweet little angels.” It didn’t take long for the mare to fall asleep, snoring contentedly with her two lovers as she dreamed happy dreams of the day her sister would marry Diamond Tiara, and of course inviting Rarity along to their honeymoon.
“Thank you again for watching my daughter for me.”
Rarity waved her hoof dismissively. “Of course, Mr. Rich. It was my pleasure, after all.”
Diamond Tiara and Sweetie Belle both giggled, confusing the stallion. “Well, it’s time for us to be heading home. Say goodbye to Rarity, Diamond Tiara.”
“Goodbye Miss Rarity,” Diamond said as she waved goodbye. “I hope we can play again sometime.”
“We’ll see,” Rarity said with a wink. After the father and daughter left the store, Rarity closed the door and turned her attention to her workstation. “Right, back to work.”
“Hey, Rarity?” Sweetie Belle asked, grabbing Rarity’s leg and looking up with a seductive gaze. “We still have some time before Mum and Dad get home and I have to go. Wanna go for another round?”
Rarity shook her head. “Sorry, Sweetie Belle, but I really must get back to work.”
“But-”
Rarity used her magic to move the filly away and started moving towards her unfinished dress. “Sorry, but I have lost too much time as it is. If you’re still unsatisfied, you shall just have to tend to your needs on your own.”
Sweetie Belle harrumphed and fell to her haunches, folding her forelegs as she pouted. “Tch. If it were Miss Cheerilee, she’d have the time.”
“Uh-huh,” Rarity said as she simply nodded. Sweetie Belle rose to her hooves and made her way upstairs. “… Wait, what?”
