It had been over a thousand years since Luna had seen her big sister, and now she stood before her just as beautiful and majestic as she remembered. She could feel her cheeks blushing, unable to hide her embarrassment at being in the form of a teenage mare.

Molestia didn’t mind. In fact, the sight of Luna the way she was so long ago caused Molestia’s cock to throb and secrete clear liquid from the tip.

“P-please don’t stare so much, sister. It embarrasses us,” Luna begged with an adorably shy expression.

“Oh but I must, little sister,” Molestia replied, using a hoof to tilt Luna’s head up, allowing the tall alicorn to see her beautiful eyes.

“You always did know just what to say to make me melt.”

Molestia lowered her head so that her mouth was next to Luna’s ear.

“Now now, Luna. Now is not the time for melting, that comes later.”

Molestia then pushed her lips against her little sister’s for the first time in centuries, and the young princess’ mind turned to sparks while her heart took off at a gallop. At this close range Luna could really smell the nasty erotic scent of her elder sister’s princesshood, so much so that she could almost taste it. A notion that made the little princess very impatient.

Luna broke the kiss and swiftly ducked under Molestia’s body, coming face to face with her massive throbbing cock. Her shaft was white with mottles of a light fleshy color towards the wide tip, which was positively oozing with crystal clear pre ejaculate.

“Oh my, such an impatient little filly we are,” Molestia teased.

“O-only because we haven’t seen it in so long. and by the looks of it, thou art quite eager as well, sister,” Luna retorted her pupils turning to pink hearts as she gazed at the engorged member that would soon fill every tight little hole in her royal body.

“Tee hee, right you are, Luna. Now, open your muzzle and swallow me as deep as you can.”

Luna didn’t argue. She opened her mouth as wide as she could and inched forward as her tongue flopped out of her mouth just in time to catch a drop of her sister’s pre. The flavor spread across her taste buds and sent shivers down her spine to her tail which flicked sharply. The rim of her cock head brushed against the corners of Luna’s mouth as it made entry.

Luna released a muffled ‘ahhm’ as the large member entered her maw and began the slow descent into her throat.

Molestia bit her lip as she felt herself slip inside a very familiar orifice. When Luna was a filly, she would often rush to Molestia’s bed with fears of monsters or the wind. To comfort her little sister, Molestia would let the foal suckle on her cock head while singing softly to her. Over time Luna became a regular blowjob princess, capable of making even the most impotent station as hard as steel.

The sun princess looked down to see a pert little rump swaying under her chest, and suddenly her mouth began to water. She dipped her head down with an open mouth, her tongue snaking out to feel around under her tail, searching for that delectable little ponut anus. Once she felt the bumps on her tongue, she immediately stated prodding at the tiny opening.

Luna felt her sisters tongue as it tried to enter her anus. She pushed out her asshole, trying to help her sister gain entry. But Molestia needed little assistance, as she had a very dexterous tongue. With a wet ‘pop’ she had invaded the moon princess’ anal cavity, and was greeted by the ripe taste of her sister’s insides.

To the ponies gathered around the two alicorns looked similar to two snakes trying to eat one another, and the sight spurred mares and stallions to engage in their own depraved sex acts.

Molestia bucked her hips suddenly, sending her cock knocking against the back of Luna’s throat, causing her to gag and release copious amounts of slobber from the little space that her sister’s cock would allow. The young mare’s eyes drifted upwards as the heavenly feeling of being used by her sister flooded her senses and made her legs wobble.

Molestia circled the tip of her tongue around the inside of Luna’s anus as if she were licking the glaze off the top of a doughnut while Luna tried to match her sister by using her own tongue to circle the flare of her sister’s second horn.

Luna felt a spurt of delicious pre splash against the back of her throat, but before she could swoon from it she felt Molestia’s cock start thrusting. She moaned from the sudden force of her sister’s fleshy battering ram. The little princess tried to straighten her throat to allow her better access, but it was hardly necessary. Molestia was going to fill her throat no matter what.

The sun princess lifted her head from Luna’s blue and black spotted ass, a rush of euphoria clouding her vision. Her curvaceous rump started swaying back and forth as she went further into Luna’s throat inch by inch, all while Luna gagged, her eyes tearing up.

Her mouth was so wet and tight, Molestia’s thoughts were becoming nothing but the desire to flood her younger sister’s belly with a gallon of her thick splooge.

The sun goddess bit her lower lip as her eyes rolled back into her skull.

“Here I cum bitch! Drown in it!”

Luna’s eyes shot open as her cheeks bulged from the torrent of molten cum that overflowed her mouth and rushed down her throat to fill up her stomach. Luna could feel the glue thick cum as it slithered and sloshed down her esophagus to settle heavily inside her stomach. The small princess gulped and sputtered as she tried to contain every drop, but the amount was becoming too much.

The next sputter saw a spray of cum fly out of Luna’s nose. The semen stung her sinuses and Luna couldn’t breath very well. Soon her vision filled with little white spots signaling a coming black out.

But before that could happen Molestia yanked her cock from her sister’s distended throat and began to plaster Luna’s face with cum. Luna coughed and gasped for air as jizz splattered on her face in globs.

Once the last spurt had been fired onto the night princess’ face, Molestia stepped backwards to get a look at Luna’s face. Molestia giggled at the unrecognizable alicorn under her. There wasn’t a square inch of space that wasn’t dripping with white seed. Her jaw was slack and hanging down as she panted and coughed up wads of cum onto the grass.

“What do we say, Luna?”

“Th-thank you cough! cough! big sister,” the young princess replied, sounding meek and tired.

“Good, good. Now turn around stick out your rear and beg me to fuck you like a two bit whore.”

Luna sputtered out a wad of her sister’s milkshake thick cum before turning around, lowering her head and raising her rump, flicking her tail to the side, revealing her sopping cunt and puckered ass.

“Please dear sister, I am but an empty and moist hole for you to use as you wish. Thrust and plow me till I am broken and whimpering, and then fill me with cum to the point that it bursts me at the seams.”

Luna’s words shocked even the most depraved ponies gathered around, but to Molestia it was akin to hearing a familiar greeting.

Molestia could hardly contain herself. The sight of Luna’s teenage plot was irresistible. So small and soft, just begging for a hard throbbing cock deep inside. Her clit was winking erratically at her, causing Molestia’s mouth to water.

“Well I do hope that you’re ready. I have centuries worth of cum for you to take, you little cunt.”

Luna responded by swaying her rump lazily.

The young alicorn yelped slightly as she felt her sister’s gold clad hooves touching her flanks, applying her weight to her hips as she raised herself up. Luna could feel the heat from her sister’s cock, and Molestia could feel the radiant heat from Luna’s snatch.

The crowed held their breath as they watched their ruler’s engorged cock inch closer to their new ruler’s dripping pussy. Molestia’s tip touched her winking marehood, drawing a gasp from Luna. Molestia’s cock pressed against her long closed pussy. She thrusts, but her dick slipped and went up her ass crack releasing a spurt of free that caused a collective gasp from the towns ponies.

Molestia pulled back and re aligned herself pressing with more precession.

Luna exhaled, pushing out with her vaginal muscles. Molestia’s cock head popped inside the slick folds.

“Oh sister yes!” Luna exclaimed as the familiar feeling of having Molestia’s fat cock head inside her. The feelings got stronger as more hard cock slid inside her long closed cavity.

There was more than half of the giant dick inside Luna now, but it wasn’t enough for Molestia. She wouldn’t be satisfied until her balls were firmly pressed against her little sister’s thighs. How Molestia had missed it, the exquisite look of intense pleasure and anguish on the little slut’s face as she pummeled the inside of her womb with her fat cock head.

“I hope you’re ready, Luna. Big sis has a, ngh! big, fat load ready to feed you!”

The sun goddess jammed the rest of her length into the young alicorn’s small frame, causing watchers to wonder how such a small and delicate looking female could hold so much cock inside her.

There was a sizable outline of Molestia’s cock bulging from Luna’s stomach, and the effects of the sizable obtrusion were evident on her face. Her eyes were rolled back to the point that they were almost all white. Her tongue hung loosely from her open, gasping mouth as her sister’s cock battered her baby room with a force similar to a ram.

“T-T-Tia! Thou art amazing!” Luna screamed.

“You too, Lulu. Good to know that your cunt still remembers my shape!” Molestia replied, emphasizing her point by jamming her hips forward so hard it almost knock Luna off her balance.

Among the onlooking throng, Twilight’s eyes widened in amazement. Never had her teacher fucked her little pussy or ass with such power. The young unicorn had started rubbing her cum dripping snatch without even thinking about it. She had never felt so good from touching herself, and from the looks of the other ponies, neither had they.

Just then Molestia raised her hoof and brought it down on Luna’s tight little rump. The small alicorn cried out so adorable that three stallions to ejaculate without stimulation.

With her magic the sun goddess grabbed a wad of Luna’s mane and yanked it back hard as she pushed in and gyrated her hips in a circle, grinding her dick head against little Lulu’s cervix.

The gyrating only lasted a moment. Molestia couldn’t contain herself any longer. She started thrusting hard and fast as liquid love dripped from her small gash, wet sounds echoing from the place they were connected. Molestia brought her fore legs together on either side of Luna’s neck, fencing her in place.

Molestia gritted her teeth as muscles clenched and hips pumped. Molestia easily blasted past Luna’s cervix and into her womb, which was ready and eager for a big drink of her sister’s syrup.

“FUCK ME, TIA! TURN ME INSIDE OUT!”

The big alicorn couldn’t hear, her mind was laser focused on the scent, sight and feeling of plowing her own sister. Through her gritted teeth ponies could hear growers and animalistic noises the likes of which had never been heard coming from a princess. Her eyes were filled the the lust and furry one would see from an arctic wolf as it malled a helpless little herbivore.

Luna’s eyes rolled completely back into her head. She stopped breathing and her jaw fell open as her tong lolled out followed by a small stream of cum from earlier.

Silence fell except for the sounds of furry and wet fucking.

The sun princess looked to the ponies watching, who flinched slightly from the frightening sight on the princess’ face.

“ALL YOU STALLIONS,” she bellowed in an earth quacking voice. “COME FORWARD, YOUR PRINCESS DEMANDS THAT YOU COVER PRINCESS LUNA IN THINE SEED!”

Without thinking every stallion gathered ushered forward. There were easily twenty males gathered around the small princess. They helped one another up onto their hind legs. They grasped their throbbing cocks and tossed themselves to the sight of the young mare’s ahego face.

“I AM ABOUT TO BLOW! EVERY ONE OF YOU WHO DOESN’T CUM WITH ME SHALL SPEND A WEEK IN THE DUNGEONS OF CANTERLOT!”

The threat spurred the males to stroke faster and faster. All of them were building momentum quickly, and everypony was on the edge of their seat for the big finish.

Luna regained consciousness to the sight of over a dozen stallions all beating their dicks and pointing them at her face and body. But before she could question what was going on, she felt a tsunami of white, hot princess cum flooding her womb, while a rain shower of spunk fell on her face and body. She extended her tongue, catching dozens of thick ropes on her tongue.

The finite room inside her pussy wasn’t enough to contain her sister’s immense load. The force shot out from around her stretched cunt like a firehose, splattering the three fillies Luna had been playing with earlier. The little ponies opened their mouthes and extended their hooves to catch the cum like snow flakes.

The flow didn’t cease, and soon enough a massive puddle of seed extended outward from around the little princess. Ponies watching the princess cum fountain bent over to lap at the giant puddle like deer at a stream.

Fifteen minutes passed before Molestia’s orgasm subsided. Big and little sister slumped down into the pool, curling together into a cuddle. Molestia stroked Luna’s mane as the little one huffed and sighed.

“Tia, I love you…”

Molestia leaned over and kissed her sister’s cheek.

“And I you, Lulu. I can’t wait to show you Canterlot. Once you get settled, I’ll get you a harem of fillies and colts dedicated to pleasuring you.”

The two sisters spooned together, each feeling a peace neither had felt in a long, long time.

Once things started to wind down, Twilight looked to the five girls who were sipping punch at the refreshments table. She smiled, though it did not last long.

A big shadow loomed over her, and she looked back to see her mentor standing with her trade mark motherly smile.

“Why so glum my little fuck toy. You just save Equestria from certain doom, and now you can return with me to Canterlot.”

“Uh, yeah, I-I’m happy.”

Molestia extended a hoof to her student’s shoulder.

“Twilight Sparkle, I was not born yesterday. Is it your desire to stay in Ponyville with your new fuck buddies?”

Twilight’s glum expression quickly turned to one of pure joy.

“Can I really? I mean, I want to get to know them more of course, and I think the country would be good for Spike. I-is it really ok?”

Molestia giggled.

“NO! Now get your little ass on that chariot now!”

Twilight’s smile shattered into an expression of shock and heart break.

“Just kidding!” Molestia blurted.

“Seriously, Twilight get a sense of humor. Of course you and Spike can stay, but I expect you to wright me lots of letters- and don’t leave out a single sorted detail.”

Twilight smiled, almost unable to contain her happiness.

Princess and student came together in a warm embrace.

“Take care of yourself, my student.”

“I will. Thank you, princess.”

Twilight found Spike just as he had finished chatting it up with one of his new “friends”. A blond unicorn filly with a grey coat. Once the filly skipped off she approached her faithful assistant.

“So, Spike, princess Molestia says that we can stay here in Ponyville. Does that sound like something you’d like?”

Spike scratched his belly. He looked over to his right at the three fillies that he had had so much fun with.

“Yeah, I think I’ll be just fine.”

“Somepony sure looks happy clappy,” Pinkie commented as Twilight approached her and the four others.

“Why yes, darling. You look positively ecstatic,” Rarity added.

“Well, I was just told by the princess that me and Spike can stay here in Ponyville!”

“Seriously? That is awesome!” Rainbow Dash cheered.

“Boy howdy, Twi. That’s dandy,” Applejack said, giving the unicorn a tap on the shoulder.

“Welcome to Ponyville, Twilight,” Fluttershy said sheepishly.

“Oh, I mean, welcome home.”

The six mares came together in a big girly hug, none of them caring that they were standing in cum or that they all reeked of sweaty sex.

The end.
