Sunset Shimmer wore a wide smirk as she walked down the long corridor of Canterlot High with a confident stride. The students occupying the hall quickly moved out of her path as anyone who had attended this school for more than a day knew to avoid this girl at all cost. Everyone knew this, everyone except the principals that is. Somehow despite Sunset Shimmer’s various acts of infamy, the two principals, Celestia and Luna, were dimly aware of Sunset’s mayhem, or if they knew, they choose not to show it. “All of that would change after today,” Sunset thought, as she strode into Vice Principal Luna’s dimly lit office, slamming the door behind her.

Luna was seated at her desk like she usually was every day of the year, going through the various papers and memos necessary to keep the high school functioning. She barely acknowledged the girl’s rather rude entrance, seeing as she’s grown tired of Sunset’s frequent visits to her office.

“What is it now, Sunset Shimmer?” Luna asked dully as Sunset took a seat, the high schooler’s smile never fading. “Another student scandal you’ve so conveniently managed to capture proof of?” she inquired sarcastically.

“Not quite,” Sunset said, slipping a manila folder out from her leather jacket and pushing it onto the vice principal’s desk.

“What’s this?” Luna asked curiously, opening the folder to discover some photos that appeared to have been taken by Sunset Shimmer’s phone the previous week. As Luna peered closer at the individual pictures, her hands started to tremble realizing what they contained.

The photos appeared to have been taken from a spot outside of Luna’s house, from a window located in her backyard that would allow anyone staring through it to get a perfect view of her bedroom.

Picture 1: Clearly showed both principals giggling like drunken school girls as they entered room, hand in hand. Clearly not taking an effort to display the strict professionalism they were known for at school.

“But this looks like it was taken during… oh no…” Luna panicked, flipping to the next picture.

Picture 2: Luna had her arms wrapped around Celestia, caressing her form as she kissed with what appeared to be some fiery passion for a single frame. Meanwhile, Celestia’s hands had worked their way under Luna’s shirt, quite obviously trying to pull it off Luna’s slender body as she returned her younger sister’s kisses with as much vigor as she was met with.

Picture 3: The now bare chested vice principal, her dark nipples clearly visible on her impressively pair of perky D-cup sized breasts, was laying in her bed giving her older sister a sultry ‘come hither’ look. Celestia’s back was facing the camera as she worked to remove the clasp of her own sheer white bra holding an equally, if not more impressive, pair of tits.

Picture 4: Luna, laying on the bed completely nude, wore a look of pure ecstasy as her tongue lolled out of her mouth, her back arched in response to the fierce tongue lashing she was receiving from her sister as she firmly gripped the bedsheets. Celestia, who was just as naked, excluding her pants she had decided to keep for now, was kneeling into Luna’s clearly shaven pussy, giving a look that seemed to suggest she was enjoying the task as much as her younger sister.

And then… nothing, that was the last photo. Luna remembered Celestia having some technical difficulties removing her final article of clothing in the heat of the moment, during which time she closed the curtains on the windows. Fortunately, it seemed to have blocked a certain voyeur’s view of the rest of the night’s activities. “So then she must have not seen…”

“Unfortunately I couldn’t capture the sounds I heard after that on camera,” Sunset interrupted with an evil grin, breaking the vice principals current train of thought.

Luna took a long deep breath, attempting to calm herself. Somehow, despite their best efforts, the last person in the world they would have wanted to know had discovered their secret incestuous relationship. This information in the wrong hands could lead not just to the end of both their professional careers, but also any chance the two sisters could show their faces in town ever again. No one would care how many laws Sunset had broken to take these pictures, the only thing that parents would think about was how the two women watching over their students acted behind closed doors. Luna realized Sunset Shimmer probably knew this, but she wasn’t about to show it.

Putting on her best poker face, Luna causally spoke “I see you’ve been digging around for more dirt again… Tell me, what would you require to keep your silence on this matter?” If Luna was to have her way, she would have used a few other choice words on the girl, but held her tongue, not wanting to stir up trouble with the student who held her and her sister’s future in the palm of her hands. The feeling of powerlessness in the face of a mere student was an uncomfortable one to say the least. She wished to be rid of as soon as humanly possible.

“One demand, singular,” Sunset replied, cutting straight to the action. “And, I think you know what that is,” she added with a grin.

Luna blinked, taken aback from Sunset’s response. She was half expecting to be giving her full authority of the school, in addition to becoming her personal house maid for life, knowing her.

“Since you were sooo kind as to block my one view half way through, I missed out on the rest of the action that night, but I still want to see it…. ALL of it,” Sunset said, licking her lips.

Luna’s cheeks blushed, clearly visible her dark skin, realizing what exactly Sunset was demanding. She knew of Sunset Shimmer in many ways, but as a pervert wasn’t one of them. Her mind quickly scrambled to calm herself and to come up with a reason, any reason, for why this perverted deal couldn’t happen! “Absolutely not! Celestia would never….” she started.

“Celestia doesn’t have to know,” Sunset interjected, leaning back in her chair. Sunset had figured Luna would argue that. They both knew how stubborn the High School Principal could get. One of many reasons Sunset had chosen to come to her sister instead. “I’ll find a spot where I can get a nice clear view of the action, without her knowing. Then, if I’m satisfied, I’ll destroy my proof, and we’ll never speak of this ever again.”

Luna racked her mind again, then finally sighed in defeat. Taking all the facts into consideration, it seemed like she didn’t have much of a choice in the matter. “We’ve meeting again tonight, around eight,” Luna said, a blush still holding her cheeks.

“I’ll be there at seven,” Sunset quickly responded, already on her way out of the door, before Luna could change her mind.

~~~~~~~~~ ~~~ ~~~~~~~~~

True to her word, Luna heard a loud rap at the door to her home at seven on the dot. Luna opened it to be meet with the still smirking face of Sunset Shimmer. “She probably hasn’t lost that expression since our meeting,” Luna bitterly thought to herself, avoiding the girl’s piecing gaze.

For the second time in her life, Sunset was able to gaze at her vice principal. Taking a long gander at her full appearance in an outfit she wouldn’t dare wear to the school, less be the victim of every other teenage boy’s fall formal proposal. Luna was wearing a thin black tank top, doing little to fully conceal the magnificent D-cups breasts hiding behind it. Beneath those, were some casual blue slacks stretching all the way down her long legs, highlighting her thin waist and firm behind, and sending a very strong hint of athleticism. Sunset couldn’t help but steal a look or two more as she was reluctantly invited inside.

“Nice place you got here,” Sunset remarked, taking in her surroundings. What stood out more than anything to her though was the pair of wine glasses, filled to the brim that laid in front of a recently lit roaring fireplace. “Classy…” was all Sunset could fit in before she felt a pair of hands on her backside pushing her towards the direction of what she could only assume was Luna’s bedroom.

“Yes yes,” a voice behind her retorted, “Our meetings don’t always end with….. certain amorous activities,” Luna coughed. “But I felt that I would take certain steps to insure that they do tonight... strictly due to our understanding, of course.” Luna paused. “And I have your word that you will keep your silence on this matter?”

“Hey,” Sunset replied defensively, “I’m a woman of my word.” as she held up her hands to show that her fingers weren’t crossed. “After all, I wouldn’t want to spend all that time blackmailing my next two principals all over again, now would I?” she asked with her usual evil grin.

Luna gave an exasperated sign again as they entered the bedroom. “You can watch from in here,” pointing Sunset towards a small walk in closet, directly adjacent to a large queen size bed adorned with silky black and blue bedsheets. “Celestia doesn’t touch my closet ever since I’ve become known for being,” Luna stopped for a moment, searching for the right words “possessive, regarding certain clothing she borrows and never returns,” Luna shoved Sunset inside. “And remember if you’re caught…”

“Yeah yeah, I’m dead, got it,” Sunset replied dismissively from inside the dimly light closet.

“We’re both dead,” Luna corrected, “My sister can have quite the temper.” She managed her own grin as the expression on Sunset Shimmer’s face visible shrank. “Now stay hidden, my sister will arrive at any moment,” Luna said, sliding the closet door closed before adding “And don’t touch anything!” before walking back into the living room.

Minutes passed as Sunset waited intently, listening for any sounds that could hint Celestia’s arrival. Finally losing her patience, she slowly stepped out of the walk in closet, seeing if she could fit in any last minute mischief. Peering out from the bedroom door into the living room, Sunset saw the back of Luna, silently reading her novel while sitting on the couch in front of roaring flames. She figured she could probably spare a few minutes to snoop around.

Backing into the bedroom, Sunset pulled her trusty smart phone out from her skirt’s pocket, setting it on top of a bookshelf angled towards the bed. Sneaking back into the closet Sunset quietly opened several drawers, hoping to find something worthy of interest. In the third drawer from the bottom Sunset’s eyes lit up with impish glee as she discovered her vice principal’s panty drawer. Quickly rechecking to ensure the room was still empty, Sunset casually slipped a pair into her pocket as a memento. However, something else caught her eye in the corner of the drawer. Lying there, plain as day, were several pieces of sheer black see through lingerie, under which laid a thick 8 inch long dildo, both by the looks of which seemed quite used.

Before Sunset could take a ‘closer’ look at this gold mine, she heard the front door to her Vice Principal’s home open and close. She hurried to her crack in the bedroom door to catch Celestia walking in, wearing her usual beige and purple Principal attire, a slight let down considering Luna’s alluring attire. The two sisters exchanged a hug and rather long kiss on the lips before retiring to the couch, toasting their wine glasses to another week’s accomplishments. Sunset could barely distinguish what the two principals were talking about, let alone hear anything juicy.

When what seemed like an eternity had passed by of random laughing, giggling, random chatter, and smooches before the two principals stood up. Their wine glasses long since emptied as they slowly made their way, hand in hand, toward the very room Sunset was hiding in.

Sunset gave a quick “eep” before scurrying back into the closet, silently closing the door save for a small crack, just enough for her to peer through yet remain unnoticed. Without a moment to spare the door burst open, the two sisters entangled in a familiar sight. Their tongues wrested for dominance in each others mouth, neither sister looking like they wanted to give the other an upper hand. Arriving at the foot of the bed, Celestia broke off the kiss, giving a smirk as she gave her sister a light nudge, pushing her younger sister onto the covers.

Luna, momentarily regaining some composure, slowly started to nervously slip backward on the bed. “Umm…. sister…p-perhaps we could take it easy tonight,” she asked, casting a few uneasy glances toward her closet. Luckily, Celestia didn’t seem to notice where her sister’s eyes were gazing as she shook her head giving a light chuckle.

“I don’t think so… Lulu,” Celestia said in a tone befitting casual sibling mocking. Then, without warning, she grabbed the waistline of her retreating sister’s pants, yanking them and her panties off in a single swift motion. Not giving her a chance to react, she placed her hands onto Luna’s knees, forcing them apart to reveal a glistening set of lower lips, perfectly shaven, and quivering with arousal.

“From the way you’ve been acting tonight, I’d say you want this just as much as I do,” Celestia said, as she worked to remove her own professional attire. The lust clearly visible in her eyes and she unhooked the clasp on her own sheer white bra, letting two perfectly shaped breasts burst out into the open. The soft, rosy aureola and hardened nipples quickly drew all the eyes in the room as even the slightest movements caused the over sized mammaries to bounce and clap together. “Ohhhh….” Celestia purred, caressing her own rack “It feels so nice to finally be able to let the girls out.”

Sunset’s eyes had remained glued to her crack in the closet door as she watched the events before her unfold, finding her face flushed, and breathing heavily. Even though she had partially witnessed it last week, she could not believe this unbelieving erotic scene between these two sexy ladies was actually happening! It was so wrong, and yet…

As she continued to enjoy the scene in front of her, a hand subconsciously snaked its way beneath her skirt, pushing her soaking wet panties aside as it thrust a single digit into her dripping pussy. Sunset gave an audible moan as her fingers continued to work, easily going unnoticed by the two sisters.

All of Luna’s clothing had once again been reduced to a heap on the floor, the two sisters had resumed their passionate make out session, their breasts pressed and rubbed into each other as they continued to roll around the bed in a fit of romantic passion. Luna couldn’t get enough of her sister when she was in this mood, it was the real reason she managed to make it through her work every week. Unfortunately, Celestia knew this weakness of hers all too well.

Finally, Celestia backed away from the kiss, a small trail of saliva connecting the two lover’s lips. “Still want to take it easy little sis?” She joked, lifting herself off the bed.

“Forgive me dear sister, I-I’m not sure came over me,” Luna pouted, disappointed that their make out session had ended earlier than normal.

“Well, now that we’ve gotten that matter resolved, would you like to do the honors?” Celestia asked, gesturing to her work pants, the final piece of clothing that had yet to be removed.

Luna’s eyes immediately lit up with a glee. Hopping down onto the floor and scooting over on her knees, Luna began to shimmy down her sister’s pants. Finally pulling them off, leaving the horny principal as exposed as her sister. Unlike her little sister, Celestia’s rump was big and large, suggesting she exercised more at Sugar Cube Corner than anywhere else. If anything though, it only served to drive Luna into a deeper state of arousal.

But as Sunset’s eyes drifted downwards at the newly exposed flesh, she gave a gasp at what she saw. Rather than another dripping wet pussy, Luna’s face was met with a thick, 9 inch cock, popping out of its confines to happily greet the blue haired vice principal. Luna licked her lips in lust filled anticipation, eyes never wavering from Celestia’s veiny member. She was obviously well acquainted with her sister’s little friend.

Wasting no time, Luna’s tongue flicked out, giving a savory licking on the underside of the rock hard shaft before her, earning a soft moan from her sister. Moving her head up she wrapped her lips around the tip of the cock, starting to slowly bob her head along the shaft, making a few loud slurping noises as she worked. Celestia shook in delight, softly panting as her she felt her sibling’s tongue ravish her length. With her free hands, Luna began to tenderly attend to Celestia’s balls while licking circles around the sensitive head, electing an even deeper moan of approval from her big sister. Luna giggled, having long since learned every nook and cranny of the older sister’s body, knowing exactly what it took to drive her over the edge.

Celestia gave a light chuckle, sensing exactly what her sister was up to, but she wasn’t about to be outplayed that easily. Reaching down, she begin to roughly knead the flesh of Luna’s tits together, suddenly giving her dark nipples a rough pinch. In response, Luna moaned in pure pleasure, which in turn sent vibrations alongside Celestia’s shaft causing it to twitch wildly in her mouth.

In the back of Luna’s mind, she had completely forgotten that Sunset Shimmer was watching their every move, too focused with the task at mouth. Placing her two hands onto her big sister’s famously large behind, Luna pulled her face downwards, causing all of her sister’s length to instantly disappear into her mouth. A slight bulge appeared in Luna’s throat and she attempted to manage her sister’s wide girth. She looked up to meet her sister’s gaze and gave a short giggle. Celestia didn’t keep it any secret how much she was enjoying every one of her sister’s actions.

Sunset shivered, finding some new found respect for her vice principal. Never in her wildest dreams would she have pictured these two having such a perverted naughty side to them. She continued to watch intently, taking in every detail of the two lovers like her life depended on it. Still unbeknownst to her, Sunset’s mischievous hands had long since pulled her skirt and underwear down, leaving her bare from the waist below. A hand was now fully committed to pleasuring her dripping wet folds, while the other was reaching under her bra-less shirt, lightly fondling a breast. At this pace, it was unlikely even her top would stay on for much longer.

Although Celestia was thoroughly enjoying the deep throating her sister was eagerly giving her, it only served to drive her more towards the main course. Looking down at a delightful sight of her sister effortlessly taking her entire cock down her throat, she decided to turn up the heat. With both her hands, she grabbed the back of her little sister’s head and began to mercilessly face fuck her mouth. She heard her younger sibling groan in excitement, only nudging her closing to the brink as she felt her member slid against her throat’s soft muscles. Her hips were practically a blur to Sunset, as her cock went in and out of the adorable sister sitting on her knees. Despite the seemingly rough treatment, Luna was still smiling, managing to press her tongue alongside the bottom of the shaft while it rapidly slid across her lips. Her eyes rolled to the back of her head, the overwhelming power she felt as her sister continued to violate her mouth made her pussy drip in arousal. She felt like nothing more than a sex toy, to be roughly used for the sake of her old sibling’s pleasure.

“L-Luna….” Celestia gasped, breaking her sister from her lust induced trance as her cock began pulsing wildly inside her sister’s throat as she continued to thrust. Luna didn’t need to hear another word. Quickly redoubling her efforts and sucking with full force, she brought her hands up to the balls of her merciless fucker, giving them a soft squeeze. This sent Celestia crashing over the edge as she came, hard. Rope after rope of sticky hot cum was pumped directly into her mouth as her cheeks bulged, struggling to contain it all. Not wanting to waste a single drop of her sister’s delicious gift, Luna focused all her efforts on swallowing every last shot of cum she was given.

After what seemed like hours, the waves of her climax died down. A satisfied Celestia pulled her member out of her little sister’s mouth with a loud ‘pop’. Luna opened her mouth wide to reveal to her lover the last of Celestia’s cum in her mouth, slowly savoring it, then swallowing it down to join the rest in her stomach.

“Mmmmm, good girl,” Celestia beamed, giving her adorable sister a pat on the head, which Luna returned with a light purr.

“Well, I wouldn’t be much of a sister if I didn’t take care of my big sis every now and then now would I?” Luna remarked playfully, giving the tip of the slightly limping cock a quick peck. “Speaking of which….” Crawling on all fours, Luna climbed back onto the bed, show casing her completely drenched cunt. She gave her rump a cute wiggle~ before looking back and giving a quick wink. “I don’t think I’m quite done taking care of you” staring at the length between her lover’s legs.

Any hint of a wilting member instantly vanished during that moment. Celestia gave a lusty grin as she practically pounced onto the bed, positioning her member between the dipping folds of her sister’s most sacred of places. Grabbing her hips as Luna silently prepared herself for her favorite part of the week.

With little force, Celestia penetrated her quivering lips, slipping her length in slowly. As Luna released a quiet moan of approval, Celestia proceed to push in relishing the full feeling of her sister’s velvety walls, before pulling out leaving only the head inside. Luna gasped in pleasure as her sister started to thrust in at steady pace.

“Lulu…” Celestia managed between grunts “It’s never ceases to amaze me how tight you are.” She could feel her walls tighten down on her girth, gripping her for everything she had, trying to keep her length inside.

Unlike Celestia, Luna was unable to respond. She was in heaven now, the look on her face morphed into one of complete pleasure. Celestia smirked, giving a particularly hard thrust into the love-crazed sister. Luna replied with a scream of absolute bliss.

Celestia continued to rut at an increasing speed as her hips moved on their own, sending her little sis into a sexy fit of moans and cries of pure ecstasy. Each penetration was returned in kind as her lover thrust back against her, continuing to drive her into a lust filled frenzy. Leaning over she began to work her sister’s swinging breasts, much to Luna’s delight.

“YES! Oh god, fuck meeeeeee…” Luna pleaded “D-Don’t, you dare stop!” Celestia had no intention of even slowing down, gripping her hips tightly and she drove herself in and out. Luna could feel every inch of her lover’s shaft as it pulsed inside her, hitting her deepest parts.

As the sex crazed principal continued to have her way with her younger sister, Luna could feel her climax fast approaching “Tia… it feels soooo amazing… I-I’m about to cum!” Luna shrieked.

“M-Me too… Lulu, I’m almost there!” Celestia managed to groan.

“Do it Tia! Fill me up! Pound your naughty little sister’s tight pussy!” Luna yelled, digging her nails into the sheets as she ground her hips back, giving the women all the motivation she needed.

With one final thrust, Celestia buried every inch of her length inside her sister, passing the point of no return, her seed gushed out, flooding the inside of her pussy. The feeling of her sister’s hot essence making its home inside her womb was the last straw, driving Luna over into her own climatic bliss. Giving her loudest scream yet as her orgasm hit, mind going blank from pure pleasure. Celestia felt Luna’s walls clenching around her cock, milking it for all it was worth, not wanting to leave a single drop of precious cum left in her sister’s balls.

Her member was happy to oblige, filling the sister’s dripping passage to the brim before overflowing out onto her legs. Both sisters continued to ride out their respective waves of pleasure as Celestia’s cock continued to pump more and more searing hot spunk into her sister’s overflowing passage. Luna had been reduced to nothing more than a twitching, moaning mess. After what had seemed like another hour, Celestia pulled her slowly deflating cock out, smiling as she admired her handiwork.

Luna on the other hand, feeling completely spent from the night’s activities, collapsed onto the bed, her arms no longer having the strength to support herself. She was soon joined by her sister, pulling her into a tight embrace, as they bathed in their respective afterglows.

After a few minutes of silent cuddling, Celestia stood up, giving her little sister one final kiss on the forehead. She gathered up her belongings and she slowly got dressed. Pausing at the bedroom door to give one final glance at Luna, sleeping peacefully on the bed, before slipping out.

Luna purred in content, satisfied with the night’s activities once again as she felt her sister’s essence residing inside her womb. She slowly closed her eyes waiting for sleep to overtake her…

~~~~~~~~~ ~~~ ~~~~~~~~~

Suddenly her eye’s shot open, just now remembering a crucial detail she had previously forgotten. Rising from the bed, Luna approached the closet door, not even bothering to cover herself. Upon opening she was greeted with a dumbfounded Sunset Shimmer, still holding an expression of complete and utter shock on her face. More noticeably though, the teenage girl was completely nude, her fingers still lying inside her glistening folds.

“Well…. I hope you didn’t make that big of a mess in there,” Luna giggled. Sunset was slow to respond, seemingly as surprised to find herself in such a state of undress as Luna was.

“Judging from the signs, I trust you were satisfied with tonight’s performance then?” Luna continued, not wanting to wait for a response. Sunset could only give a few light headed nods.

“Excellent!” Luna said, clapping her hands together, adding to her good mood. “Now if you would please excuse me, I think we can both agree I am in a dire need of a shower.” Luna walked out of the room, wiggling her ass one final time to tease her perverted onlooker.

Sunset Shimmer shook her head to compose herself. Quickly gathering her wits, she picked up her clothes and slipped out. However, not before grabbing her phone off the shelf, which had, of course, recorded the entire night.

Author's Note

Well I hope you enjoyed my first story ever. I know some people probably would have enjoyed it more with any Sunset Shimmer. But to be honest, I liked adding something else besides just sex, it was a fun little experience for me (as was writing the rest of this thing) and if I were ever to write more of these, I would probably add a bit of a twist to them like here.

Also feel free to give any feedback or corrections. There should be quite a few of them as I am probably the last person in the fandom who should be writing. But I may write another chapter though if I find people like this and I feel up to it.
