In the hills of the Ponyville countryside, where only few houses stood anymore, the sun was setting. It bathed the lush, green landscape into a peach-colored light. A filly with a name that fittingly reflected this color, Peachy Pie, sat at the dinner table and watched the fiery spectacle through the window. Her eyes were glowing, partially with the reflection of the orange light in them, partially from pure fascination over what she saw.

Peachy sat next to her sister, Sunny Daze. Sunny was the older one of them, a filly with a mane and a tail that were as yellow as the sun. Sometimes, Peachy teased her with that, saying that if the sun should ever fall from the sky, they only need to put her in its place and eternal night will be avoided. But it was never meant spiteful, only as a lighthearted joke the seven year old filly liked to make about her older sister.

In response to this, Sunny always said that Peachy also looks like the sun with her orange mane and her orange tail, just when it was about to go down instead. Then she stretched out her tongue. It was a comment that could be interpreted as Sunny expressing to feel superiority over her sister, because she was one year older than her but, in reality, it was just as much a lighthearted joke as what Peachy liked to say.

In fact, both of the young sisters liked to refer to each other as such. One of them represented the sun during the day and one of them represented it during sunset. It was how they viewed each other, both of them representing a different appearance of the sun. It was their little game and when they teased each other like that, it never happened out of malice. It always was, without exception, an expression of how much the two filly sisters loved each other.

And loving each other they did. One only needed to observe them for a brief moment to see it. Right now, sitting opposite of their parents and with a nearly finished dinner in front of them, Peachy and Sunny sat very close to each other. They always sat very close to each other during meals, with just enough distance between their chairs so that they wouldn't constantly poke the other while eating. Which none of them would have minded, but it were their parents who insisted on a certain distance between them when they ate.

Peachy Pie and Sunny Daze were different than most foals. Unlike their classmates, the two sisters preferred to stay for themselves. They went home from school right after the bell rang, not joining the chit-chat between the other foals that usually continued for a couple of minutes after the last lesson. They made their homework together, on a big desk they shared, then they played together in the grassy fields and the hills that surrounded their house. Or inside, with one of their toys, when the pegasi made it rain.

At first, their parents were concerned because neither of them was making any friends. They had been talking it over with both of them, tried to encourage them to warm up to their classmates by inviting some of them into their house and by making arrangements with the other parents for Peachy and Sunny to get invited to their foals' birthday parties.

But nothing ever stuck. While Sunny and Peachy did not actively exclude other foals from their games, they also weren't too interested in them and often ended up getting distracted with each other.

Over time, the parents gave up, also because other foals grew more and more frustrated with their daughters. Nopony they asked for help could really explain it but, eventually, Peachy's and Sunny's parents followed the advice to just let them be if the company of each other sufficed for them. They learned to accept that their daughters were different, but happy with the way they lived.

And said way of living included a surprising amount of desire for body contact. Peachy Pie's fixation on the sinking sun got interrupted as she felt her sister's hoof patting her back. She turned around and barely finished the movement before Sunny Daze crushed her with a tight hug. Peachy's chair swayed a little. For a moment, she felt like she would lose balance, while her big sister gripped her tightly and rested her head on her shoulder. But the chair did not fall.

Peachy reciprocated and wrapped her hooves around Sunny. The embrace lasted only for a second, then Sunny brought the tiny gap between their chairs behind her and climbed into the lap of her little sister. They were about the same size, but Sunny had to inch back a little regardless, so that her head could reach her sister's chest. She rubbed her cheek at it tenderly and simultaneously drapped her little hooves around Peachy's back again. Peachy did the same with her own hooves, then nestled her chin into Sunny's mane. She closed her eyes and cooed softly.

While making the necessary room for the intimate gesture, Sunny had been hitting with her flank against the table. Her tail flicked over Peachy's plate. It pushed it over the table a little and got smeared with butter that was on Peachy's leftover bread.

Their parents looked up and it was their mother who addressed the situation. “Sunny, let your little sister eat.”

Inching around and looking over her shoulder, Sunny acknowledged the request with narrowed eyes and a pouty face.

“But I like Sunny's snuggles, it's okay, mommy,” Peachy intervened. Her eyes looked a little sad.

“Um-um.” Their mom shook her head. “You know what we talked about last week, no snuggling at the kitchen table. Mommy and daddy don't want to clean up broken plates and glasses again.”

Now it was Peachy who pouted. “But–” she started, but got interrupted by her dad.

“Listen to your mom, you two.” His voice was more stern.

“Aaaaaaaw,” Sunny and Peachy moaned at the same time. It caused their parents to smile, but their insistence remained.

Sunny's lips quivered as she looked up at her little sister. Peachy stroke with her hoof over her mane in a lovely, comforting way, then Sunny climbed out of her lap and back into her chair. She still pouted and gave her parents frowny looks as she finished her meal. Peachy's expression wasn't much better. The faces of the two sisters indicated that the presents for the next Mother's Day and Father's Day were on the line.

Peachy Pie grabbed her last piece of bread and put it into her mouth with one hoof. Her other one reached to the left and rubbed over her sibling's back.

And that's how it always was between them. Sunny and Peachy never left each other's side and not only were they connected in their minds like filly sisters rarely were, they also were unusually affectionate with each other.

They sat side by side during dinner, they had been nagging their teacher until she allowed them to move their desks together (resulting in it that half of the class suddenly demanded the same permission), the shared desk in their bedroom at home was a wish by Peachy for the present on her seventh birthday a few months ago and they even refused to take a bath if they couldn't do it together.

No matter how many other couples with foal siblings they were asking, Peachy's and Sunny's parents never heard anything that came even close to the deep bond that was between their daughters. Both of them wondered when they would ask them to buy one huge bed for their room and to throw out their old ones. Snuggling was a constant for the two sisters, it was only a matter of time until they would develop the need to sleep in the same bed together.

But such was the nature of Sunny and Peachy and their parents have learnt to live with their quirks. At least it was endearing and they came to appreciate that their daughters weren't fighting all the time, like it was so common for siblings.

The piece of bread swallowed, Peachy suddenly coughed. She started retching, then reached into her mouth and pulled a few yellow hairs from her tongue. She placed them on the plate.

“Your tail hairs were on my bread, Sunny!” Her voice did not show any hints of annoyance. It sounded amused, actually, almost pleased.

“Teehee!” Sunny giggled. Playfully, she swished her tail at her sister. The tips of the last hairs at its end tickled Peachy's chin and she giggled, too.

Both of their plates empty, their mom regarded them again. “Are you two finished with eating?” she asked.

The two fillies nodded and rubbed over their bellies, demonstrating how full they felt and that nothing would fit in anymore.

Their mom nodded, satisfiedly. “Good, then get up and ready for bed!” she said.

Eagerly, Sunny and Peachy climbed down from their chairs. They cantered to the other side of the table and crushed their dad with a hug together, then proceeded to do the same with their mom.

The mare squeezed her two fillies. “Don't spend too much time in the bathroom. And, Sunny, make sure to get all of the butter out of your tail, okay?” She felt the nod of her older one at her neck, then the sisters released their mother and galloped up the stairs.

Half an hour later, Sunny and Peachy left the bathroom. With slightly damp coats and grins on their faces, they entered their bedroom. They stopped in front of Peachy's bed, which was distinguishable by the happily smiling peaches on the bedding. The two sisters turned around and faced each other. Raising their forehooves, they initiated a tight hug.

Peachy rubbed with both forehooves over Sunny's back as she felt the warmth of her older sister's body pressing against hers. “I love you, Sunny, good night!” She nuzzled Sunny's cheek.

Sunny squeed at the touch. She made the embrace tighter. “Good night, best little sis! I love you, too!” She planted a kiss on Peachy's mane.

Then Peachy pulled away. She slipped under her blanket, but let a hoof stick out. Sunny picked it up and began stroking it, which caused Peachy to form a huge smile. This went for a minute, then Sunny reached into the bed and wrapped her little sister into another hug. The two fillies stayed like this while their mom entered the room.

“Alright, now it's bedtime for you two!” the mare chimed. “Sunny, let your sister sleep now. You know you have an important test at school tomorrow.”

Immediately as the words washed over her, Peachy froze. She started to shiver slightly.

Sunny felt it on her body. She slowly let go of her little sister, but not without giving her a wink in a way so that their mom couldn't see it. It made Peachy smile again and her cheeks began to flash a rosy color.

“Now, hurry!” her mom spurred Sunny on. “The bedbugs will bite tonight if you don't climb into your bed now!”

Sunny frowned. “Mommy, I don't believe in bedbugs anymore!” But she followed the command, trotted up to her bed and climbed under the yellow blanket.

Both fillies where they were supposed to be now, their mother let her eyes wander over them. “Are you ready to turn off the light?” she asked them.

The fillies nodded in unison and their mother gave each of them a kiss on the forehead. She approached the light switch and turned around. “Good night, my precious ones. Mommy loves you.”

The fillies grinned. “We love you, too, mommy! Good night!”

The mare gave them one last smile, then the room became dark and she went outside and closed the door behind her.

Peachy and Sunny listened to her mother's hoofsteps as she went down the stairs. They heard her trotting around below them. Then it became quieter. Faint, low mumbling sounded into their ears.

Now feeling safe enough, Sunny's face shot at her little sister in the dark room. “Are you scared because of the test again?”

Immediately, Peachy's face distorted and she nodded, her lower lip poking out. “I can't sleep, sis!” she whimpered. A few tears formed in her eyes.

“Do you need my help?” Sunny's eyes became a beacon of compassion.

Peachy nodded at her older sister, lips pointing down.

“Hang in, sis!” Sunny spoke fast and climbed out of her bed. On gentle hooves, she pranced around Peachy's bed.

Arrived at her sister's side, Sunny reached for the nightstand and pulled out the top drawer. She tapped around inside of it until she found a small nightlight. Sunny placed it on the nightstand and switched it on. A smiling moon and happy clouds appeared on it and a warm, blue light spread out. It was just enough to light up the immediate space around Sunny. The light got reflected in the tears of her sister, who looked at her with a longing expression.

Sunny reached into the bed and crushed her younger sibling with a tight, comforting hug. Then she removed the blanket from her body. Gently, she grasped Peachy and lifted her stiff body up, then carried her close to the bed's edge and sat her down there.

Peachy wrapped her tiny hooves around her chest and looked down at Sunny, unhappily. “Will this help, Sunny?” she chirped in quiet sadness.

Sunny looked into the eyes of her little sister. “It will help, it worked every time, don't worry!” She reached with a hoof into Peachy's mane and stroke it tenderly. As Peachy's expression resisted, she leaned in and kissed her cheek. “Soon you'll feel better and can sleep, little sis.”

Done with the affectionate gestures, Sunny returned her attention to the lower part of Peachy's body again. She placed her hooves on the slender, yellow legs in front of her and gently spread them apart. A faint blush appeared on her cheeks as she looked at her sister's privates. The same happened to Peachy as a small, pink nub slid out of them.

Sunny placed her hooves on the left and right side and gripped her younger sister's flanks. Peachy's legs were now hanging over her forelegs. Sunny looked up and into Peachy's eyes. “Remember to be quiet,” she whispered.

As Peachy nodded, Sunny looked down again and back between her legs. She gripped a little tighter, to make sure Peachy would stay in place, then she leaned forward and licked over Peachy's fillyhood.

Immediately, Peachy breathed out. A grateful smile formed on her lips.

Sunny answered the smile with one of her own, then she closed her eyes and started a series of licks. She moved her tiny tongue up and down her sister's slit, slowly and carefully.

Peachy watched her older sister from big eyes, occasionally opening her mouth. The tongue moving up and down between her hindlegs was wet and it tickled her, which she acknowledged with a quiet giggle. Completely without Sunny's doing, she spread her legs a little further. “Hmmm...” it escaped her.

“Are you starting to feel better?” Sunny asked between two licks, without opening her eyes.

“Y-Yes, Sunny. I-It becomes warm.” A moan followed her words.

Sunny smiled. She continued the good deed for her little sister and above her, Peachy smiled, too.

Over time, Sunny's constant licking made her tongue wetter. Her glands produced more and more saliva and while some of it went down Sunny's throat, a few bits ended up on Peachy's puffy fillyhood. Peachy felt the wetness and her vagina started to tingle. She moaned again and released her hooves, that had still been wrapped around her upper body until now. She leaned back and pressed her hooves into the mattress behind her. Peachy closed her eyes, too, and another moan left her.

The younger filly enjoyed the tongue of her sister quietly for a few minutes. The warm feeling became more intense and it made her feel increasingly cozy. Then Peachy opened her mouth to ask a question.

“S-Sunny?” She breathed out strongly again, her chest heaving.

“Um-hm?” Sunny did not open her eyes while she continued to help her sister relax.

But Peachy opened her eyes now. “W-Why do you think Mommy and Daddy always say that nopony is allowed to touch us down there, when it makes me feel so much better?” She took a closer look at her fillyhood. Her lips had become spread and gave her free sight at the pink flesh under them. Peachy swallowed, then a third moan came out of her mouth. It lasted longer than the previous two.

Below her, Sunny shrugged. She stopped and looked up. “I'm wondering, too,” she answered. “It feels great, isn't it?” She performed more licks to underline her question.

“Y-Yes,” Peachy confirmed. “I-It makes me feel even better than... Mmmmh... t-than snuggling. Aaaaaah...” She squeaked, adding more confirmation.

“That's good, but remember to be quiet, okay? I don't want to get grounded for this!” Sunny closed her eyes again and continued with the caressing.

“I-I will...” Peachy promised. “Aaaaah...” She focused and managed to make this moan sound quieter again.

Peachy's fillyhood began to feel wetter and wetter. Soon it was more than Sunny's spit. A familiar feeling arose between Peachy's legs. It felt just as it did when she had to pee, but she knew it was different.

The first few times, Sunny and her had been thinking that licking her down there causes her to pee automatically. But then, one night, Sunny filled the liquid into a cup and they examined it. They discovered that it was much more sticky than pee and that it also smelled differently. Peachy had been worried that their parents would find the cup and punish them for doing something naughty. But Sunny just drank it and destroyed the evidence with that. Then she tossed the cup out of the window and it disappeared between the tall grass of the fields around their house. Peachy wondered if it was still there.

Now that she was leaking again, what Sunny and her have decided to call “peach juice”, Peachy could hear her sister swallowing in short intervals. The sound got added to the slurps Sunny's tongue produced as it lapped away at her.

“D-Does it... Mmmmh... Does it still taste good, Sunny?” Peachy looked down again. Now she was gaping widely and she had to squint to distinct her sister's tongue from the inner parts of her fillyhood.

“Yes, it's great!” Sunny moved away a little and held a hoof at her mouth. It became sticky immediately. She giggled. “We should bottle it and sell it as lemonade!” There was a naughty look in her eyes when she moved the hoof back to where it was.

Peachy frowned and poked out her lower lip. “I'm not a lemonade cow.”

Sunny giggled again. She got up from her knees, but without removing her forehooves from her sister's flank, and nuzzled Peachy lovingly. “Aww, I'm just joking. But it really tastes great. You should try it one day.” She got down again and continued. A tiny puddle did become formed on the floor in the meantime.

The suggestion let Peachy gag a little. The thought of drinking from herself made her nauseous for some reason, but she soon forgot about it as the tongue of her big sister created more pleasure for her. The little filly let her mind drown in it again and closed her eyes once more. Her chest heaved much stronger than a few minutes ago and her breath did become fast.

The warm feeling that her fillyhood was full with started to spread out. It rose higher and reached her tits. It made the tiny nipples stiff. They began to feel hard and, unlike earlier, it made Peachy groan in discomfort.

“Sunny? Can you lick my nippies?” she asked her big sister after having opened her eyes again. She looked at her with an intense frown. “They feel strange.”

Sunny nodded, wordlessly, and moved to the slightly higher spot. It was the only thing that Peachy didn't like about Sunny's relaxation method. But they found a solution for this too.

First, Sunny licked over each of Peachy's nipples a few times while collecting spit in her mouth. Then she wrapped her lips around each and let the spit come down on them. It coated Peachy's nipples and made them moist, which eased the rigid feeling.

“Is it better?” Sunny asked as she was finished, looking up at her little sister.

“Um-hm. Thanks, Sunny.” Peachy's face looked relaxed again.

Sunny flashed a smile upwards, then her tongue returned to the soft, wet spot below Peachy's tits.

As the minutes passed, Peachy could feel that the licking of her sister became faster. Sunny produced a moan, too, now.

Caused by the new tempo, Sunny's nose began to stroke Peachy's clit. It made the younger sibling breathe stronger each time her clit got touched by her sister's soft nose. Suddenly, she had problems to stay in her position. The little jolts of pleasure that came from her clit increased the warm, cozy feeling tenfold. As it reached her belly, the licking started to feel much more intense on the sensitive skin of her fillyhood. Peachy shivered and her forelegs felt wobbly, so she gave up on her position and sank down on the mattress.

Lying on her back, the moans filled the air above her. They became more lustful. And after a series of such moans, a particularly loud squeal surpassed them.

Sunny stopped licking and gritted her teeth. Her head shot up. “Peachy!” she hissed. “I told you to be quiet! What if mommy and daddy hear you?!”

Peachy twitched and immediately pressed her hooves on her mouth. Her eyes darted around, then she sat up. At full alert, both sisters listened for sounds on the stairs, frozen in place. It was a matter of seconds for them to slip back into their respective beds, if it became necessary.

Three minutes passed, then Sunny breathed out in relief. She looked at her sister sternly. “That wasn't quiet, Peachy,” she whispered.

“I'm sorry.” Peachy Pie frowned, feeling treated unfairly. “I couldn't help it, your tongue feels so good!”

“Okay. But we need to do something about it.” Sunny retreated and crawled under the bed right between Peachy's legs. Her coat got smeared with the puddle of “peach juice” as she did so. As she appeared in front of Peachy's eyes again, she was holding a lathy, green pillow.

“Press this down on your mouth,” Sunny said as Peachy took the pillow out of her hooves. She used it as instructed.

The naughty hazard under control now, Sunny returned into her old position. Seconds later, Peachy could feel the beloved tongue sliding over her crotch again. The sounds of muffled moans that left her mouth and got absorbed by the pillow became a regularity now. Peachy couldn't avert her eyes from what happened between her legs anymore, it was intoxicating for her to see the tongue of her sister doing its job to make her feel so good.

After a couple minutes, Peachy rose her head slightly and squirmed. A long-stretched moan indicated that she was close to the relaxation she sought. Feeling unable to stay upright once more, Peachy lied down on the mattress a second time. Her short, slim legs twitched as her breath increased its pace rapidly.

Sunny noticed the reaction. “Do you want me to stick it inside, too?” she asked.

“Y-Yef!” it came in response, enthusiastically.

Fulfilling the wish, Sunny moved her tongue in the middle of her younger sister's pink and moist fillyhood. She aimed for the hole in the middle and poked it in carefully.

Immediately, Peachy arched her back. “Thunny!” it sounded out from under the pillow. Her eyes rolled up as she felt Sunny's tongue explore her insides. “Faster, Thunny!” She squeaked in pleasure as she felt the tempo of the tongue increasing as result of her command. “You arw the beft sister, Thunny!”

Sunny smiled over the compliment. She pulled her tongue out of the wet hole for just a moment, a string accompanying it, and placed a kiss on her little sister's clit. It caused Peachy to lift her hips a little.

Without really noticing it, Peachy moved one of her hooves down and began to stroke it over her tits. It was the last thing she needed.

“Aaaaaaaaaaaaaah!” Peachy moaned one more time as she felt something hot spreading out inside of her fillyhood, like a self-heating pad was suddenly appearing in it. A second later, Sunny was rewarded with an additional torrent of warm and sticky fluids. It flooded directly on her tongue, then into her mouth. Greedily, the older filly swallowed down the peach juice she loved so much. As nothing was left anymore, she pulled her tongue out and away and sat back. She bit off the new string that connected her mouth with her younger sister's entrance.

“You are the best sister, Sunny!” it came from the bed again. Peachy's voice didn't sound muffled anymore.

“No, you are!” Sunny panted. She leaned back and propped herself on her forehooves.

Looking up, she could see how her little sister sat up. “No, you!” Peachy frowned.

“Uh-uh.” Sunny shook her head. “You are!”

“No, it's you!” Peachy protested.

“No, you!” Sunny counter-protested.

“You!” Peachy shouted, barely keeping her voice low enough, and getting close to her sister's face.

“You!” Sunny brought her face closer, as well.

The two sisters stared at each other with frowns for a moment. Then their lips curled upwards simultaneously. They started to laugh and fell around each other's necks. And stayed like this for a moment, before Peachy used all her strength and pulled Sunny into her bed. Her hooves lost their grip eventually and the two sisters fell into the bed at each other's side. They laughed again.

Sunny turned at Peachy. “Do you feel better, little sis? You think you can sleep now?”

Happily and with satisfaction adorning her face, Peachy nodded. “Um-hm. Thank you, Sunny!” She inched closer and nuzzled her sister, which got reciprocated by the other sibling.

“Good, then let's go to bed quickly, just in case mommy and daddy heard our shouts and come looking!” Making good on her words, Sunny moved down Peachy's body and planted her mouth one last time between her legs. Diligently, she licked her little sister dry. Then she took a tissue out of the nightstand and cleaned up the moisture on her own fillyhood. She crumpled the tissue and shoved it between the nightstand and the wall.

Sunny jumped out of the bed. Quickly, she leaned down on the floor and licked the puddles away, one from Peachy and one from herself. Finally, she turned around at her little sister and tucked her in. Sunny placed a kiss on her forehead. “Good night, Peachy!”

“Good night, sis! I love you!” Peachy smiled at her big sister in gratitude while rubbing with her hoof over one of her eyes. She yawned heartily.

“I love you, too!” Sunny flashed a smile back, then she switched off the nightlight and put it back into the drawer.

On gentle hooves, just like before, she pranced around Peachy's bed and slipped back into her own. As she turned around at Peachy again, she could already hear quiet, steady breaths. Her little sister was asleep.

Yawning herself now, Sunny pulled the blanket up to her chin. A second later, hoofsteps on the stairs made her twitch. She turned to the other side quickly and pretended to sleep.

The door of the filly sister's bedroom got opened quietly. Their mother took a peek inside. As she heard nothing but steady breaths coming from her two little daughters, she closed the door as quietly as it had been opened by her before.

“Asleep so quickly, where other fillies suddenly get up and start to play with their toys again and are a huge bother for their parents before they finally go to bed. We really raise two very lovely and innocent daughters,” she thought in pride and smiled as she went back down the stairs to her husband in the living room.

Upstairs, though, Sunny Daze was still busy. Under the blanket, she was finishing herself. A spray of her very own juice squirted out of her fillyhood and soaked her bedsheets. She licked it off her hoof and then fell asleep, as well.
