Luna gets something new and Celestia really wants a turn

Human

(Futa warning)

Celestia awakes to a surprise that has Luna looking brand spanking new. It's exciting, it's alluring, it's enticing and all natural, or should I say, she is.

Same Old Same Old

“Luna! Your body!” Celestia jumped when a tingling sensation woke her in the middle of the night.

“WHAT! WHO ATTACKETHS?!” Luna nearly had a heart attack as she flung herself away from her sister’s body, which she had been using to pillow her head. Her hand grew ablaze with dark blue as she immediately she swatted her chest and arms while she scanned the room with frenzied eyes.

Then she stopped.

Three things happened at once: she spoke, gripped her chest with both hands, and looked down.

Make that four things. Sparkling blue hair blocked her view as it waved itself into her mouth, so she sputtered.

“Yeah, my hair does that too.” Celestia commented, some of the amusement in her voice lost as she looked at her sister with wonder.

“What…?” Her eyes were wide, but not from fright. She teleported off the bed, not even bothering to use a light spell on the room, and landed in front of her full length mirror that hung on a closet door.

She had boobs. Her skin was darker. Her voice more mature. Taller…? Yes taller, and she had boobs!

“C- Celetstia?” She stuttered, not quite used to the new voice. It was calming, she liked it.

Luna didn’t even bother to look back at her sister as she held her naked chest in her hands. Celestia snapped and the candles in the room lit up.

“Congratulations, Lulu. You’ve just gotten your new body.” Celestia stared at her sister’s new curves and color. She was conflicted, she liked her sister the way she was before, but this new figure look delicious too. She would wait for Luna to have fun checking herself out before she took her turn to explore.

“No kidding.” Luna twisted herself this way and that, running her arms over herself and craning her neck to get a new angle.

She was dark, well she was darker than Celestia anyway, and not by much but enough to see the difference. She would have definitely contrasted her old light olive tan had she been able to stand next to herself. Her hair took the blue of night and swayed gently as though a sweet breeze flowed through it. She could see the likeness of the stars she commanded reflecting in it.

“Wow,” she wondered aloud, getting herself adjusted to the new sound.

Luna liked her new skin. It was alluring, exotic, and made her electric teal eyes stand out. Her face was full, but was sharper, giving her womanly appearance a mixture of seriousness and mischief. It also helped that her lips were poutier, though still not as overwhelming as that Angelina Ponie woman.

Her arms stretched above her head while she gazed at their new reach, watching the way her longer fingers tickled the air as she wriggled them. She flexed a muscle, smiling that it appeared she gained some strength. Her shoulders stayed petite, but her natural pear shape had expanded across her hips. Her hands moved flat over her stomach and sides.

“Mmm,” she hummed bordering a laugh as she felt her cutie mark. The only change was that it grew bigger to accommodate the body.

Her legs looked longer, but they were thicker as well and sported a larger pair of round cheeks. She slid her hands across them as she turned in the mirror so that her backside faced it, and licked her lips.

“Oh yes, I like this.” She said giddily, mixing her voice with moans and giggles just for the fun of it.
Luna bent over to get a look at her other new pair of lips. She wondered vaguely why there was no hair there.

She was going to spread them to inspect her pink center, that was steadily growing more excited as she reconnoitered, but was distracted by the new weight hanging on her chest. The moon princess looked down to see her own pair of pendulums swinging in unison.

Balancing with a hand on a lap, she used the other to measure the heft of one tender breast. It didn’t just fit in her hand anymore; it spilled over and squished through her fingers. She rolled one then the other, then hugged them both and watched as they fell and jiggled.

“Ha, I really like these.”

Standing up and facing back to the mirror she lifted one to her mouth. Lowering her head she caught the pinkish tan nipple in her mouth, with a broadened smile and an excited moan. She could barely do that before.

She gasped and let it fall back down.

“It’s wonderful that you’re enjoying your new body, but if I have to wait any longer I may just tie you to the bed post and make my turn exploring you a very teasing one.”

Celestia was behind her suddenly, pressing her front to her back by holding one of Luna’s breast in her hand. Her breath was warm and husky in her ear, sending shivers down her novel spine.

“Point taken,” her voice lowered. It wasn’t a bad idea, but it seemed like an empty promise. Her sister was rolling her hips against her behind in a slow but antsy rhythm. Luna bit her lips as Celestia tailed a hand along her smooth darker stomach.

Looking into the reflection, Luna could see the hunger in her sister’s eyes as she roamed her body. It made the night princess smile that Celestia was so eager to touch her. She let her hand rub her sister’s cutie mark on her hip from behind.

The sun bringer was still taller, it wasn’t a surprise; and her breasts were still larger, Luna didn’t need them pressed into her back to be sure, but as a whole she no longer felt dwarfed. Her eye level well reached her sister’s chin instead of just below her shoulder.

Luna’s head rolled to the side as Celestia’s mouth ravenously clung to her neck, making Luna reflexively drop her jaw when she found her favourite spot. She didn’t have to lean as far as she used to, Celestia liked the convenience.

She wasn’t usually impatient or greedy, but tonight the foreign beauty before her made her hungry with lust and curiosity. So far she learned that Luna’s favorite spot was still on her neck and she was ready to discover more consistencies.

Her sister’s fingers had been dancing across her stomach for a while, but just before she let them plunge between her heat, Luna moved them away. Celestia lifted her eyes to her sister’s reflection.

“What?”

“You didn’t ask,” Luna pretended to look cross.

“Oh ho, and I have to ask to touch you now.” Celestia asked with false indignation.

“That’s right, Celestia. You have get permission to play with new things.” Luna rolled her hips into Celestia’s as her eyes glimmered in the mirror.

“And what if I don’t want to?” Her other hand was still on her sister’s breast. She pinched the nipple.

“I- ah, maybe I’ll make you.”

She scoffed. “What, with this body, little sister?” She tweaked the bud again and Luna bit her lips. Celestia wanted to bite it too.

“I'm not so little anymore, ‘Tia.” She tried to turn around in her sister’s hold, but was stopped when strong arms pulled hers behind her back.

“Really? I hadn’t noticed.”

Luna tugged, but didn’t try to break free just yet. “I think you have. You’re practically drooling on my shoulder. Show some restraint.” Luna turned her nose up as took an air of importance.

“I can restrain you.” Luna almost smiled at the fast reply. Celestia was really getting into her role. “And you should watch your tone, Luna. I’m still bigger than you.”

“Oh, is that what this is about? Your Spoiled Highness feels insecure with her baby sister’s new looks. Afraid you’ll lose the spot li-“

Luna couldn’t finish as she felt herself shoved against the cool mirror; it made her hiss. She felt Celestia bite that spot on her neck that made her head spin. Moaning on the glass, she barely registered the fog she was creating.

“It’s Majesty, and I am only ‘afraid’ that I have to remind you to have some respect.”

Her smooth hips and heavy chest rubbed against her sister’s back. She felt her try to pull her arms away, but she was pinned securely. Celestia’s mouth assaulted her neck and shoulder, while she ground a rhythm into Luna that moved her against the glass.

Luna could feel her sister move down her back. Soon she was on her knees, but she never released her grip on her wrists. She only moved them to her sides to press them against the mirror.

“You are the one who needs reminding.”

It was terribly lame, Luna knew, but she was distracted by her sister’s movements. Celestia’s tongue glided down the curve of the moon goddess’ behind. It moved from one cheek to the other, serving as a bridge to her warm tickling breath. She lapped the edge of the cutie mark before she took an inhale of the need growing between her sister’s legs. She smiled knowing Luna would be enjoying this.

“You smell delicious.” Completely ignoring her sister, she stood back up. “I want to see you on that bed.”

“Say it nicely and I’ll consider not kicking out of my room.”

Tugging just a bit at Luna’s ear, the sun goddess growled,

“Bed.”

It was a command, and it made Luna’s stomach flip excitedly. She knew who was taking charge that night.

Celestia let go of her wrists as she backed away. The lunar princess started her way towards her bed, but halted at a gesture. When the older woman was on the bed comfortably, she spoke.

“Slowly.” The sun goddess snapped her fingers, dimming the light in the room by extinguishing a few candles. Luna was bathed in a soft glow that made her copper tone come alive.

Luna didn’t have to listen. She could just teleport if she wanted, but what she wanted more was to see the look in her sister’s spinel eyes as she obeyed.

Step by step, Luna advanced. Her hips swayed as her thick legs brushed together for the first time. Her cutie mark rocked on the tide of her pace, her mounds punctuated her footfalls, and her glittering hair drifted over her shoulder. Celestia hummed happily.

First her knee hit the foot of the bed at a side, then her hand, her next foot and next hand had her completely on the mattress. Luna crawled in a diagonal from the corner of the bed until she was face to face with her sister at her side, making sure every movement was slow and exaggerated.

Luna’s simmering eyes met Celestia’s. She hadn’t seen her that excited in a while; she wondered agog what was going to be in store for the night as she let a leg swing heavily over her sister’s. She smiled when her sister’s mouth crashed against hers.

The kiss was sloppy and loud. The moon princess wound her fingers through Celestia’s hair, while she did the same. The older sister pulled their bodies closer together in a tight hug, rocking a pattern as their tongues dueled. It wasn’t much of a fight, with Celestia’s blood boiling so hotly.

She was glad to know the spots she brushed and tickled were still able to drive Luna crazy. Soon the night princess was moaning into her sister’s mouth while their chests rubbed together. The older sister moved quickly, only pecking a few times over the neck. Their fingers interlocked as the sun goddess continued her trail.

Celestia’s teeth scraped across the collar bone then over the larger set of twin mounds that she would have to get accustomed to.

“What are you- oh…” She was back to grating her pearly whites along the skin. The nipples hung lower down, so she had to lower her head more than usual, but she found one and suckled sloppily. Letting her tongue work again, rolling and flicking over the raisined bud. That was a nice change as it was usually she who paid diligent attention to Celestia’s breasts.

What the sun mover did with one she did with the other, taking turns as to not abandon. Luna’s moans only just over powered the lewd slurping sounds bouncing off her chest. All around the pinkish buttons glistened in the low lit room when Celestia pulled her mouth away with a pop. Luna thought she was satisfied but then her back arched when she felt teeth carefully roll her nipple.

She wasn’t sure what she wanted to do with them, but Luna really wanted to move her hands. Maybe to run though her sister’s hair or to take a handful of her sister’s chest, but Celestia held firm never giving her the chance. She tugged, but wouldn’t be set free.

“’Tia, let go.”

“No,” she said after she removed her mouth from Luna.

“Let go.” She tugged again to no avail.

Celestia shook her head sending a ripple down her own glorious tresses.

“It’s my body,” Luna heaved once more, frowning at her sister’s stubbornness.

“And what if it’s not?” Celestia asked with a smug grin.

“Wh-“

“What if tonight you're mine, Lulu?” Celestia growled.

Not giving her time to think, Celestia rolled to the side, putting Luna on her back. She leaned over her sister to capture her mouth in a steaming lock. She massaged her fuller lips, pulling on the lower one when she wanted her to widen her jaw. When Luna did, she slipped her tongue into her sister’s mouth to let it taste every inch of the inside.

Letting a knee fall between Luna’s legs, she pressed their chests together. She stopped the kiss to speak. “I should be taking it slow, right?” She kissed her. “But I thought about it, Lulu” she kissed her again. “I have the rest of forever to look at you,” another peck. “We can take it easy another night.” More time passed that time, and her tongue brushed against the ridges of her roof making the woman under her shudder. “Right?”

“Oh, yes.” Luna moaned into her mouth as she fought to let her slick appendage have a turn inside her sister. The sun princess only yielded for a moment before reclaiming her dominance. To prove her point she ground her lap on the night bringer’s wetness.

“So let me suggest to you the plans for tonight.”

“Ung ‘Tia...” Luna gasped, scarcely aware that her legs spread, attempting to feel more from the rubbing. Celestia ground with more pressure at a slower pace, making her sister’s abdomen quiver.

“I’m going to touch you, where ever I want.”

Luna nodded and the grinding came faster.

“I’m going to taste you whereever I want.

She nodded again and was rewarded the same. Her eyes were shut as she listened to her big sister.

“You’re going to do what I tell you.”

The nod came slower this time, so Celetia slowed to her sister’s discontent.

“And you’re going to cum.” Luna’s eyes opened to meet her sister, her voice only slightly labored as she instructed.

“But only when I let you. Only when I want to see your beautiful scrunched up in pleasure or when I want to feel you dripping little hole squeeze. Is that clear, Lulu?”

“And if it’s not?” It sounded cheekier in her head than in the strained way she said it aloud, but it was evident in her voice that she was close.

Celestia chuckled in the back of her throat. “Either you are willing or I’ll make good on my word to tie you up. So do you understand?”

The younger sister nodded as she almost reached her peak.

“I said do you understand?” Celestia slowed despite how good it felt to rub herself against her sister’s thigh.

“Yes, ‘Tia.” Her hips pushed against the larger woman but she kept breaking the rhythm to keep her from her goal.

“I didn’t say you could call me that.”

“Ugh! Celestia.”

She still wouldn’t give herself back to her sister. “That either.”

Luna grunted, what else could she call her? “…Princess!” Celestia’s leg was back and rubbed with vigor against the woman below her. Then she saw her eyes closed tightly as her hips went up to meet Celestia’s. She came back down when the orgasm receded.

“Good. Now get on your knees Lulu, I still have more of you to see,” she said after she rolled of Luna. Her voice was a hair off brusque, but the younger still did as she was told.

Celestia looked excitedly at the round bottom in front of her face. She had moved behind to view one of Luna’s most notable new traits.

Luna’s backside had always been rounder than Celestia's, firmer and more defined even though her hips were smaller. Even now her broadened size was still not quite up to her older sister, but she still had the better rump. And actually, it was even better than before.

Celestia’s hands slid over the cheeks. With one hand she grabbed a fistful, firm, but yielding.

“Ow! What was that for? Ow! ‘Tia! Ow!” Luna clamped her teeth before she could get any more hits.

The other hand disciplined the smaller woman. Celestia rubbed the pain away from the spots she hit as she explained. “The third one was for calling me ‘Tia, the second for questioning me, and the first was simply because I wanted to.”

“Did it have to be so hard?” the pout was evident in her tone.

She got her answer with another smack. “Now, don’t move until I say so.” Luna huffed in agreement while Celestia ran her hands up and down her behind again. She pushed, pulled, and rolled her sister’s backside around in a larger grip than she had even needed, causing a beautiful red hue to spread.

Every little tug seemed to cause a rippling that she was falling in love with. It made Luna's black cutie mark shake in the most tantalizing way. She just had run her tongue on it. So she did, she traced along the outside perfectly. It sent shivers down Luna’s back.

Soon her tongue didn’t just trace, it tickled the smaller circles, then the main picture. Luna was trying very hard to keep still, but her sister’s persistence was killing her. While Celestia’s face was on one side toying with her, her hand was on the other side kneading into the flesh in all the right places, especially right under the cleft.

She may have lasting a while longer, but she shifted in search of a bit of friction when she felt her sister’s big tongue glided against the whole thing and circle back around for the little white moon.

A loud sound of skin on skin resounded. “I thought I told you to stay still. Apologize,” the demand emphasized as she squeezed tight on one the side of the cutie mark.

“Sorry,” Luna gasped out.

Celestia’s hand connected with her hotly, dealing another whip. “What good is an apology, if it is not addressed?” She was really enjoying herself, her voice transposed itself to a no nonsense teacher.

“I’m sorry… Princess,” Luna grumbled. She could almost hear her sister smiling as she obeyed, she risked curling her lips while Celestia couldn’t see her face.

“There, that wasn’t too difficult.” The younger princess nearly groaned as she felt warm air against her wet lips. The roughness of her sister’s commanding voice sent blasts of air that excited her center. A moment passed as though Celestia was considering something.

“Shake.”

“What?”

“Shake,” she said again, but this time demonstrated by moving the handful in her grasp.

“But you told me not to, Princess.” She said too cutely.

“Now I’m telling you to, so shake.”

“Someone’s indecisive,” Luna mocked her sister, but grunted as her rear was struck again. Finally she swayed her hips, letting the movement ripple behind her.

Celestia just leaned back for a moment as she watched her sister shimmy, enjoying the way her hand prints melded into a general sea of rolling blush. “Faster.” Luna complied as she heard the hunger in her sister’s voice. “Up and down.” She changed the direction of her movement, rocking back and forth on the bed so that her tush bounced.

The bouncing was Celestia’s favorite. “Put your head down.” Luna's head moved to rest on her arms as she folded them. The day bringer was hypnotized by the way the heart shaped bottomed undulated, especially as it dropped. She couldn’t just stare, she had to taste.

The princess of the night didn’t stop moving when she felt licking on the cheeks. She only let out a small chuckle and kept rolling her hips. The chuckled melted into a moan when she finally felt a slick texture slide along her lips.

The taller woman buried her face between the wobbling mounds and let her tongue explore the familiar terrain in new style. She hummed excitedly at the same savory taste. Between her own legs was whirring, but she wanted to lap at her sister first.

Luna felt hands on her thighs, she didn’t understand at first, but soon realized Celestia was pushing her legs together. She closed her legs and moaned as she felt the tongue wriggle harder in her pressed lips.

Large hands kept her spread and massaged her cutie mark. Celestia was humming in pleasure as she spread her tongue wide across the damp hole and the hard bud. Waves of excitement were rolling through the smaller sister’s stomach as she felt another climax building.

“Ugn Tia-“ Celestia stopped lapping to bit the back of her thigh. “Princess!” Luna’s legs quivered, she wanted to separate them again.

A finger founds its way into the wet center while Celestia focused on the bud below. She could feel Luna clenching around her so she moved slowly.

“Princess, please!” She was panting through her mouth. She didn’t move a hand to finish herself, intent to show she had more restraint than her sister, but it was becoming increasingly difficult.

“Please what?” She asked nonchalantly, but on the boarder of annoyance; it was just her finger working her sister.

“I want to cum,” Luna was getting more bothered as Celestia continued to dwindle her speed.

“I don’t see your point. I said you will cum when I want you to,” she replied shortly.

Luna could only growl as she made an effort of pumping the finger inside of her to bring her own release. Celestia merely removed herself at the attempt.

“Come back.” It was a demand more than a plead.

“No.”

“I said, come back.”

“Make me.”

Luna had had up to the top of and with Celestia’s big head. She raised herself back onto her hands before turning over to sit. The sister’s locked eyes in heating staring contest.

Celestia just cracked a smile when Luna lunged, pushing her to her back. Luna pinned her, but the sun goddess used her larger legs to muscle them over. She was still stronger, but Luna was annoyed. Before Celestia could steady a grip on her wrist, her supporting hand was pushed, knocking her over.

Luna took the opportunity to wind her legs around her sister’s back and flip them over, bringing her back to the top. Usually, Celestia could just use her weight to stop her sister quickly, but now Luna could actually hold her own.

They grunted and panted as they rolled around the bed, trying to get the other to yield. Occasionally, they held up in a stiff lock, not admitting that it was partially to catch their breath. It would have been a sight to see the two most powerful women, sisters and co-rulers, naked and sweating, grappling amongst the sheets.

“Give.” In the glowing room, Celestia’s heavy chest glistened from excursion, rising and falling noticeably, but with more control than the woman she pinned with her knees. Purple orbs pointed alit and smug.

The night goddess simply panted. She hoisted and heaved, but the body above her was still too great. It took much will to swallow her own satisfied grin, knowing she fared much better in one of these scraps than before. She didn’t verbalize it, but shot defiance with her eyes, not ready to admit defeat.

“Give.” Celestia commanded again, suppressing the urge to wet her lips induced from the way Luna’s jaw jutted and lips pouted boldly. She wanted to run her tongue along the altered shape that held familiar actions. The younger princess did not reply.

“Give.” Force was added as she bounced her weight down, making Luna narrow her eyes for a moment in discomfort. She tried once more to pull free from her sister’s kneeling pin, but she was stuck.

Luna couldn’t help herself as she licked her lips. Celestia’s bare bottom was sitting high on her torso, allowing her a front row centered view of the puffy lips between her legs, though she kept her glare upwards. The aroma assaulted her nose. Turning one way or another would not have enabled her to avoid it, but she couldn’t say she wanted to.

The sun princess scooted forward as her strong fingers griped Luna’s forearms keeping them to the bed. She stopped pass the breasts and sat on her chest, closing in on the limited space between her lower lips and Luna’s upper.

“Give.” A sly idea tugged the corner of Celestia’s mouth.

Was it a threat or a promise? Luna’s eyes fell for only a second.

She could do any number of things at that moment: use magic, use flight, use her leverage to knock over her sister now that she shifted, but Luna couldn’t find herself wanting to. Celestia’s scent hit her nose and it was amazing as she was ready for attention. Luna felt her breath pick up as she licked her lips again.

“No.”

“Then, you’ll take.”

Slicked folds of flesh crashed around her mouth. She hid a moan, while Celestia did not. Her smugness dropped from her face while she ground herself on the pair of lips under her. They were soft and plump, but firmed as they consented to her pleasure.

Much time passed before Luna hummed for air- one of the perks of their great lineage- but it wasn’t until she lurched that she was granted any. The starry haired sister gasped for oxygen while she heard talking.

“Are your new lungs… not as good as the old?”

“Pouting… looks much better…on me, ‘Tia,” she panted as she remarked on the condescending way Celestia hung her lip. She would have gasped if she could when her mouth and nose were sealed again without warning on an exhale.

“Princess,” she insisted “and yes, I agree, Lulu your lips… just have a versatility that mine… lack.” Celestia bit her lip when a tongue slithered out and lapped at her bud. She could have smiled, Luna knew the rules: perform well, get air, instead her eyebrows slightly furrowed in concentration.

She roughly rolled her hips as the wet limb flicked across her quickly and directly, just the way she liked it. Her sister begged for air again, but Celestia ignored her, choosing instead to watch the red flush spread on the bronzed skin. She released the prisoning grip on her arms to ball up waving blue hair at the roots. The tongue founds its way inside of her, forcefully shoved deeper as it was rode intensely.

She had to punish her sister for slipping yet again, and she was close, her legs began to tighten around the assaulting head. The stroking was back on her pearl, pulling out groans from the back of her throat. Luna whimpered to breathe. But she wouldn’t harm her. She knew what Luna could take and was more than excited to find that she could handle even more now.

“Give,” Celestia could feel her stomach tightening as pleasure rolled through her. Her face was concentrated on the treatment below, her hips ground against her mouth mercilessly just on the boarder of climaxing.

Luna nodded as desperately as she could with her head confined. Refreshing air flooded her needy lungs. Her head swam, her eyes took a moment to focus, her heart pounded in her ears, and she could only gasp for a while, which was made easier when Celestia lifted completely off of her.

Tasting her lips, she swallowed her sister’s nectar as she caught her breath. Luna was sure she was dripping onto the bed, so she could only imagine how badly Celestia was swimming in herself. She’d just experienced it firsthand, after all.

She was leaning against the headboard on some of the few pillows that managed to avoid scattering haphazardly. Her legs were open and she was panting, but her eyes focused as if consciously making an effort to refrain from touching herself.

“Sit up.” Luna did so, only thinking about how gravelly her sister’s voice was. “Spread.” Nodding, she moved her legs. “Touch yourself. I want to watch you.” Her lids hooded as she nodded again, ready to display for her sister.

“Yes Princess.” Celestia almost laughed.

Instead she watched as reformed hands raised to the base of the swaying tresses, combing it up and letting it fall back slowing to the will of its own gravity. The hands slid down the side of her head, one feathering her neck while the other lingered by the cheeks to gather the liquid that had dribbled but was too far to reach with her licks.

Celestia’s eyes steadied on the fingers that brought the remains in between the marvelous pair of lips. Luna hummed when the finger was sealed, which paired in time with the other hand that grasped her round altered chest. The sun princess felt herself wanting to knead the flesh for the smaller woman, but only watched her do it instead.

The fingers, shades darker than they once were, were suckled, necessary to value every drop of flavor they offered. They were pulled farther into her mouth with suction, but the moon herald’s noises as she treated herself did not satisfy.

“Louder.” Soft moans rose in volume and conviction. Luna smirked when she combined that with a lewd gesture of splitting two digits around her tongue as she opened her mouth to lap between. Celestia’s legs trembled as she hummed deeply in approval.

Her light nipples were pinched by the dry hand, pulling them taunt before letting them bounce in individual massages. The wet hand finally left the cave to continue the downward journey. It moved to her golden abdomen, tickling in circles while leaving a shiny trial.

The sun mover failed to hide a moan as her sister moved her hands between her legs, her attention forgetting the other hand on the round chest. She was disappointed when Luna decided to only trace the inside of her thighs. Celestia’s legs closed just a bit, not quiet able to hold back her excitement any more. She pinched her own pink nipples.

Teasing herself in a dance across the skin and just barely on her damp folds, the night painter also teased her big sister, whose eyes stayed intently on her hand, to be sure she didn’t miss the moment she entered herself. Knowing Celestia was so much farther along than her; she arched her back and whimpered as she withheld her own pleasure.

Her other hand dropped down to her hip. She started from the middle of her lap and used her fingers to claw just hard enough to leave an ephemeral red trail that complemented warmly her fresh completion. Her sister’s eyes watched it hungrily. She took that moment to pass though her wet entrance.

It was in her line of vision, but Celestia wanted to be looking right at the curtained lips when they were pulled away. She glowered at her sister.

“Oh!” Luna made sure to exaggerate her motions as she pumped herself, but the teasing had done a number her too. She put extra effort into making the squishing noised that accompanied her pants. Her hips found a rhythm with herself. When she locked eyes with her sister she felt exhilaration tug at her stomach.

“Come, Luna,” the mandate sounded so serious she almost did.

She didn’t want to stop, but she complied by crawling until her face was in front of the diarch, who wasted no time sealing their mouths. It was another loud greedy coordination of lips and tongues, and it lasted a while with a succession of breaks in between.

Celestia’s ragged inhales and exhales calmed enough to permit her to move on. She pulled sloppily away from the copper goddess before her, gesturing her to sit down back to front.

She ambushed a shoulder while she let her soft hands glide along the curves of the inner thighs she spread. Moans and quivers let her know the action was appreciated, so she stopped and listened for the disappointed sigh.

She spoke hotly in her sister’s ear. “Continue.” Shivering, Luna plunged her fingers to bring herself back up. Her head rolled back onto her sister when she stopped hyperbolizing, letting her sister hear her for real. The new musical voice ranged a tad lower. It was more mature and captivation, so she used it to her advantage when the groans passed her lips.

Celestia rocked a motion for the both of them, gripping Luna’s cutie mark with one hand and her breast in another. As soon as she was close Celestia pulled her wrists away, not releasing her until the buzz passed.

“Kneel in front of the headboard, and then continue.”

“Yes, Princess.” Luna grunted, but listened. She shut her eyes and noticed the bed shifted. Something soft like a pillow shifted under her. When she looked she was right, and soon after came the head of her sister.

Fingers dove into her, pumping in an out quickly. She could feel her sister lapping at the juices that trailed down her leg.

“I want to hear you, Lulu,” she said with authority. “That fascinating new voice of yours.”

“Ung, Princess! Oh!” She could feel herself welling up.

She moved Luna’s fingers out of the way to use her hot tongue. She lapped at her widely and Luna got the urge to sink down on her. Her legs shook as she lowered just a bit.

“Ye- ah, yes Princess!” Celestia’s wiggled her head wildly, she could feel Luna clenching around her.

“Ah! Dammit, ‘Tia!” Celestia’s hand found her sweet spot with her fingers causing her legs widened as she tried to sink her hips reflexively.

A warm rush of liquid leaked into her mouth, but she didn’t slow, she simply drank from her sister while her fingers continued to thrust. It wasn’t until she was close again that Celestia slowed to a halt, then relocated.

“Kneel over here.” Breathing coarsely, she moved to all fours in the center of the bed. Her wondering towards the proceeding events was cut short as a weight was added to her back.

Celestia’s balmy stomach and breasts settled against her as she was mounted from behind. Her thoughts were interrupted again when fingers swirled around her bud.

“Keep us both up.” Steaming puffs of air crashed behind the shell of her ear sending a pleasant shiver down her back. She was sure her sister felt it.

As she stroked her sister in a reach around, she kept her hand on the mattress to support herself. She could tell when Luna was close, so each time she pulled away just in time.

Luna’s arms trembled from repeated teasing, which signaled Celestia to add more of her weight. Soon she was leaning heavily on Luna, who was struggling under the load of another person and repeated denied finish.

She wanted to push her sister off, but it was an interesting challenge. She wanted to see how long this would last, not just with herself, but with her sister. She had been ready to cum a while ago. It was pure will power that she let the night drag on.

Celestia waited for a very long moment. It was driving Luna mad as the buzzing between her stomach died down and her arms grew warier. Finally, Celestia moved. And it was right off of her sister’s back, much to her relief and chagrin.

Sitting splayed again, Celestia told her sister to turn around. She immediately looked at the dribbling juices between her legs. She saw her sister’s second divulgence, raising a large sun tanned breast to slurp the pruned nipple.

Their eyes met and Luna felt compelled to move when she saw the powerful brew of desperation and command. She crawled between her sister’s legs, lower her head with her tongue stretched out. Her breath along the damp folds caused Celestia’s eyes to pinch tight in anticipation, and then stopped before she tasted the drowning excitement.

“Where are my manners? May I, Princess?” Nodding quickly, the older princess stomach fluttered at the puffs of air.

She could have teased. She might have been punished, but she could have easily teased. Yet, if anything, the night had been a tease in and of itself. Instead, she gave her sister what she wanted. Her thumb found the button begging to be pushed and prodded.

She whimpered on the boarder of a real shout from Luna’s ravishing digit. The moon princess wanted a taste, but only managed to dip her tongue into the winking hole when she felt a grip on her hair pull her up. She slowed her thumb and raised her eyes, lifting an eyebrow.

“Ask again.” Celestia just wanted to hear it one more time. ‘May I, Princess’ and she would let lose all over her sister’s face. She saw amusement sparkle in her sister’s eyes as she retracted her tongue. Luna raised herself to eye level in her kneeling position.

“Princess Celestia of the Equestrian Kingdom, may I, your humble little sister, stick my tongue in your most royal dripping snatch until you cum around my mouth.”

She meant to nod, but she came rather to a belly quavering orgasm, hard and loud as her back arched roughly. Her legs closed tightly around Luna’s hand. She was just able to slide her finger inside of her sister, giving her something to clench around.

Their lips met in a languid kiss while she rode herself out, head fallen back and fingers running through her hair. Luna only waited for her to relax to pull her hand away, but these was enough liquid down there to have made the job easy, regardless. Luna was still excited, but she thought after that her sister would have been done. They did need to transition the sky in a few hours anyway.

She was mistaken, but not disappointed.

“Uhng…”

Luna pulled on the magic restraints around her arms. She wasn’t trying to break free, she just didn’t know what to do with herself. Her sister’s tongue was very skilled, and she ran it up the length of her magic summoned cock, around the head and back down, all the while tickling her with her breath.

Why had she chosen now to slow down now? Hadn’t she said she had other nights to do that? So why was it that the pink muscle traced her member so very leisurely? Couldn’t her sister just put it in her mouth already?

“What was that, Lulu?” Celestia spoke amused against the stiff flesh, smiling as her tongue only inched along.

“I- uhh” Her sister kissed the head and poked it for just a second with her tongue. Luna tugged the bonds again.

“Hmm?” She wickedly drew out her questioning hum, just to make her sister squirm.

“Please…”

“Please who?”

Why she was obsessed with that title, Luna might never find out, but at least she knew why her sister didn’t urge Twilight to call her by her name.

“Please, Princess.” Luna made a relieved grunt when she was finally given the smooth texture of her sister’s mouth enveloping her shaft. As soon as her lips sealed around it she sucked with fevor, bobbing her head with expert precision along the length.

That part of Luna had also changed. It was longer and had a wider girth. It held the same brown that dusted skin with a pink head that matched her nipples.

It was normally much easier to take her sister down her throat, but now she had to open her mouth wider and resist gagging to get her mouth all the way down. She liked the old size, the way she could get her thumb to reach the first knuckle of her middle finger when she used her hand. Now she could just reach the tips.

She removed her mouth from her sister without a suction that would dry her off. Celestia wanted her slick, though she was sure it was hardly necessary with the puddle of juice that had cumulated between her own legs.

Something told Luna to open her eyes, so she did, and they were met with the same hungry gaze her sister held all night. The contact stayed even as Celestia positioned herself above Luna’s rod. The princess of the moon wanted to see herself slide in, but those purple eyes were commanding her attention.

One hand held the member in place, while the other kept her poised just above. A moment passed with a silence that ragged panting and thumping hearts only intensified. They didn’t do anything but share a glance.

Then Luna felt herself bottom out. She saw her sister’s eyes widen, losing focusing for a moment when she dropped without hesitation. She saw her sister bite her lip to keep from making noise, failing as she grunted. She saw her sister’s floppy sweaty breasts bounce as she rode her, and she saw the hand that had held her cock in position relocate, using her arm to bracket the mounds. And, she saw her sister’s own thick member thwacking against her stomach. She felt it too.

Celestia leaned forward letting her chest rest on top of her sister’s. She pressed them close together and cupped her sister’s face. Her lips captured her sister’s greedily, pulling on the warm flesh and sliding her tongue through her parting teeth. She kissed her deeply and moaned as Luna kissed her back, lacking tact with the distraction of her sister’s walls.The sun princess didn’t mind, she loved making her sister lose focus.

The new voice didn’t change what sounds she made, just the way they sounded. The Luna under her, grinding her hips to match her and resisting the urge to break the magic bonds to touch her back, was the same Luna that had been with her through the eons.

What parts of her were foreign only offered a new bit of interest to their easily dull lives, but nevertheless belonged to the same familiar sister Celestia loved more than anything in the world.

“Princess,” Luna groaned against her sister’s mouth, she was farther along so Celestia ground her hips faster, barely rising off of her sister, and she shook her head, removing her lips from Luna’s to catch her breath and speak. “Not Princess… ‘Tia… please…”

“Uhn! ‘Tia! ‘Tia! ‘Tia!” Luna was close, she tried to hold out, to finish with her sister, but Celestia grazed her teeth on her neck, right on her favorite spot. Her faux cum hosed inside of her sister as her back left the bed. Celestia came after, and her cock shot its load, smeared in between the sandwiching of their stomachs.

The shafts faded away, leaving two spent sisters panting and relishing in the afterglow. Celestia broke the spell that bound her sister, but didn’t feel the need to roll off of her. Normally, Luna would rest on top of her until they either fall asleep or decided it was time to get back to work. Luna didn’t seem to mind, she even enjoyed resting on the bottom for a change.

“’Tia?” Celestia’s head rested on her sister’s shoulder.

“Yes?”

A pause and then she said, “I love you.”

Celestia smiled, she hadn’t been expecting that. She knew her sister loved her, but she didn’t think it would have been one of those nights she would hear it. “I love you too Lulu.”

After some time Luna spoke up again. “’Tia?”

“Yes?”

She paused once more. “Lulu?”

“Do you think…” Her voice trailed off as she lifted a few locks of her nighttime hair.

“Do I think what?”

She sighed, “Never mind.”

Celestia lifted her head to look into Luna’s eyes. “Was I too much?”

“What do you mean?”

“Tonight, everything, was I too much? Maybe I have gotten off of you sooner or-”

“No, no, it was fine, I’m fine. Ok? Don’t worry.” Luna smiled at her sister, knowing how concerned she could be.

“Are you sure?”

Luna rolled her eyes but nodded. “Really ‘Tia, and I think I enjoyed myself about half as much as you did.”

Celestia squinted. “You know what? Your sarcasm comes across better with your new voice.”

Luna giggled a little, “But I do mean that I’m ok.”

“Then what is it?”

“Never mind ‘Tia, it’s silly.” Her head was turned away to look at one of the few candles still lighted and dancing as she frowned slightly.

“Not silly enough to make you sound so worried. If it’s so silly, then we can just laugh about it together, but it seems to me that it’s something you should ask.”

She started a few times, not quite wanting to speak. “…Do you think I’ll frighten them?”

“Who?”

“Everyone. Do you think they’ll be afraid when they see I’ve changed?”

Celestia hadn’t thought about that, but now that it was called to her attention her smile dropped with Luna’s.

“We can explain to them how this is a natural change, but yes, they might be startled at first. But you haven’t changed on the inside, though. They’ll see that you’re the same Luna who rules the night and loves her subjects.”

“They’re your subjects really.”

“There our subjects and they’ll see that you’re the same old Luna, just in a brand new body.” She kissed her sister’s temple before putting her head back on her shoulder. “And I’ll be by your side, Lulu, so you don’t need to worry.”

Before they fell back asleep they climbed out of bed and showered, preparing for the new day they would have to start soon. Luna finished before her sister, so she opened the glass door that lead to the balcony. Celestia came up behind Luna, watching the ridged way she stood. She slid her arms around her waist and breathed in the scent of her just washed hair and the cool morning air.

“Lu, they already love you, they’ll just have to get used to you in a new form.” She felt she sister’s hands come up to meet hers as they looked across the rolling landscape of their empire. “It won’t take too long either. You saw how quickly I pounced at you.”

At that Luna chuckled. The moon drifted to the horizon but waited patiently for permission to tuck away until its rest was over. As Luna nodded, her sister stepped away from her ready to take flight and paint the day.

When she landed, she and Luna walked out of the bedroom towards their small dining room for breakfast. It wasn’t protocol but Celestia held Luna’s hand. Luna wouldn’t admit it out loud, but she appreciated the gesture more than it made her feel sort of silly for needing her big sister.

But that was ok. She’d always want her sister by her side and some things never change.
