Chapter 1 -- The Meeting

The dark purple unicorn woke from a late sleep, but noticed it was still night-time. Groggily, she rose to her hooves and rubbed sleep from her eyes. She gave a quick look out the window to see four stars working their way inexorably towards the moon, which still contained the silhouette of the mare's head.

I'm late, I'm late, I'm late she thought as she rushed from the library towards Town Hall, the designated spot for the Summer Sun Celebration. Her long strides allowed her to make time quickly as she galloped at top speed, occasionally glancing at the moon before returning her attention to the path in front of her. She noticed the stars go behind the moon just as she caught sight of the massive assembly of ponies gathered around a stage which had been constructed to welcome Princess Celestia. Another glance revealed the lack of a silhouette on the moon's surface as she wended her way through the throng of ponies to meet up with her housemate, Twilight Sparkle.

"Hey, Twi, did I miss anything?" Amethyst asked in an almost flippant tone of voice, even going so far as to tack a nervous chuckle onto the end of her query. Before the librarian could answer, a loud gasp resounded through the square as a dark mist swirled around the upper level of the stage. Rarity had somehow made her way up to that second level and announced that the Princess was missing. The mist coalesced into the form of Nightmare Moon, her armor gleaming in the moonlight, an evil grin etched on her visage.

"Oooh, she's pretty!" the dark purple mare blurted, perhaps a little too loudly as several ponies turned in her direction. Apparently, she had spoken those words loudly enough for the dark alicorn to hear them as well. Amethyst's smile faltered as Nightmare turned her head in the mare's direction, then glided down to the ground, landing gracefully, then slowly trotting towards her.

"Hmm, so you think I'm pretty, huh? And who might you be, that you would be so bold as to compliment me so soon upon my arrival?" the alicorn asked, her voice an almost sultry purr as her grin widened. Her sharp canines gave the purple unicorn pause, her voice wavering slightly with her answer.

"I -- I am Amethyst Shadow, your majesty," she replied, bowing slightly towards the alicorn. Her grin widened further at this.

"Amethyst Shadow," the alicorn stated softly, mulling the name over in her mind as she struck a wistful pose.

"What have you done with our Princess?" asked one of the assembled ponies, who had taken the momentary distraction to group together tightly.

"Am I not worthy of your admiration? Am I not royalty enough for you?" the alicorn asked, glaring harshly at the assemblage. There were murmurs among the crowd, the ponies shifting nervously on their hooves as they waited to see what would happen. The fact that one mare was brave enough to stand face to face with the dark alicorn was enough to fill the air with a great deal of tension.

"You're royal enough for me, your majesty," Amethyst giggled, redirecting Nightmare's attention. "And if anything, your sheer beauty exceeds that by miles," she added coyly, batting her eyes at the alicorn.

"Are you trying to seduce me? You? Amethyst?" came the incredulous query, Nightmare's eyes widening in surprise.

"Amethyst! What are you doing?" asked Twilight.

"Never you mind, Twilight," the purple mare huffed before returning her attention to the alicorn. "Nightmare Moon -- I'd like to do more than just seduce you," she grinned, her giggling seemingly infectious as the alicorn's visage changed from stunned surprise to mischievous grin.

"What do you have in mind, Amethyst?" Nightmare asked, her voice having an even more sultry tone to it than before.

"There are quite a few things I'd like to do with you -- but not here, not in front of so many ponies -- what I have in mind is something we need a more discreet location for," she replied softly.

"I believe I know just the place," the alicorn chuckled as she wrapped a wing around the dark purple mare and teleported away with her.

"Amethyst!" Twilight shouted as they disappeared.

"Who was that? Where'd that purple unicorn come from? How did she know what was going to happen? Where did they go?" were some of the questions asked in rapid-fire fashion from a number of the ponies present. Twilight backed away from the group and galloped as quickly as she could to the library in order to search for some answers. She was quickly followed by Rainbow Dash, who flew above to follow; Pinkie Pie, whose galloping outpaced Twilight's; and Applejack, Rarity, and Fluttershy, whose speed couldn't match the other two.

The dark alicorn teleported to her private bedchamber within the castle ruins in the Everfree Forest -- the jaunt took a little effort, but the resulting disorientation shook the purple unicorn more than Nightmare Moon. It took Amethyst a few moments to recover from the trip, the alicorn watching in mild bemusement.

"Wooh, could you give me a word of warning next time you do that? Oooh," Amethyst moaned softly as she held her head in her forehooves and sat on the floor of the room. "Oh, and could you turn on the lights? I can barely see in here," she added, eliciting a soft chuckle from the alicorn.

"Of course, my little Amethyst," purred the lunar princess as she lit her horn and bathed the room in a soft blue glow. "You complimented me on my beauty earlier -- tell me, little one, am I still beautiful to you? Are you still willing to give me what I want?"

"Mmh, give me a moment, please -- your teleport took more out of me than it did you -- ooh, my head," the unicorn groaned, still holding her head. Nightmare chuckled softly.

"Take all the time you need -- there will be plenty of it."

"Uh, where are we?"

"We are in my private bedchamber -- which still looks as it did before I was sent away," the alicorn mused as she went to her bed and checked it for softness. "Yes, this will do quite nicely. Tell me, little Amethyst -- what would you like to do first?" she asked as she reclined on her bed, flashing a wicked smile at the unicorn.

"Oooh -- could you take off your helmet and armor? It'll help things a little," Amethyst noted, though she instinctively licked her lips upon seeing the alicorn's sexiness for the first time. Upon seeing the unicorn's reaction, Nightmare nodded her head and swiftly removed her helmet and armor in eager anticipation of what was to come. Amethyst slowly made her way over and sized up the alicorn, taking in the sight of her teats and marehood, though that was not where she was going to start. "Mmh, Nightmare -- your beauty is far greater than I had ever imagined," Amethyst uttered softly as she climbed onto the bed beside the alicorn, lightly touching her muzzle to that of the alicorn's, then nuzzling their muzzles. This made the alicorn giggle in response, then lick Amethyst's muzzle as well. Amethyst responded by kissing Nightmare on her lips, then Nightmare responded by opening her mouth and deepening the kiss. The two explored each other's mouths, their tongues wrestling for dominance, their breathing becoming shallower and more rapid as they continued to kiss. Nightmare used her mane and wings to caress Amethyst's body while the purple unicorn ran her hooves over as much of the alicorn's body as she dared, the two breathing sharply through their nostrils as they continued to kiss with a deep passion. Eventually their breath gave out and they pulled back from the embrace, a string of saliva connecting their lips.

"You are very good at that, little Amethyst! Tell me, is there more you can do for me?" Nightmare purred sultrily.

"That's just to get warmed up, your Majesty," the unicorn grinned as she nestled against the alicorn and began kissing her down her neck to her barrel, occasionally nipping at the alicorn's fur. Nightmare's breath hitched for a brief moment as she was taken by surprise at the level of passion Amethyst was showing her. The alicorn giggled softly, her breathing becoming a little shallower as the unicorn made her way down to the teats. Amethyst nibbled lightly at each nipple, swirling her tongue around each one in light circles, causing the alicorn to gasp and moan in lewd pleasure at the sensation.

"Mmm, you're very good, little Amethyst -- but you can bite them harder if you'd like," the alicorn offered, her voice soft and matronly. The unicorn obliged, biting the nipples harder, eliciting louder moans from the alicorn, now arching her back as the sensation increased her passion. "Mmm! Do more!"

The unicorn now licked the alicorn's pussy, lubricated with her juice as the passion and bliss had readied her for this moment. Amethyst licked and sucked with intensity, lapping at the dark folds of the alicorn's pussy, causing her to moan even louder than before! Amethyst giggled with her mouth on the alicorn's pussy, the sensation causing her to shudder with the pleasure she was receiving.

"Mmm, you like that, don't you?" Amethyst asked, grinning slyly at the alicorn, her face wet with pussy juice.

"Oooh, you are so goooood! More! More!" the alicorn commanded, though her big grin showed her enjoyment of the treatment she was receiving.

"Mmmmh, I have more surprises in store for you, your majesty," Amethyst offered, her grin widening at the thought of what she was about to do.

"Good ones, I hope," the alicorn responded, giggling at the prospect of what was to come.

"Yes'm," Amethyst replied before returning to licking and sucking the alicorn's dripping wet snatch. Using her magic, Amethyst created a couple of magic dildos, one she inserted into the alicorn's pussy, the other into her rectum. The sudden insertion of these magical constructs caused the alicorn to let a scream of surprise and pleasure escape her lips.

Chapter 2 -- Delicious Desire

"Oooh, if I didn't know any better, I'd swear you were a virgin," Amethyst giggled. The alicorn shuddered in pleasure, her pussy becoming freshly lubricated with more juice. Upon noticing this, the unicorn returned her mouth to the source of the liquid and began lapping it up around the dildo as best she could. "Mmm, tastes like blackberries," she mused before licking and sucking with increasing passion. She could feel herself getting quite wet on her nethers and was beginning to feel an aching need herself. Her horn lit up with magic again, catching the interest of the alicorn. Another magic dildo formed, this one with two protuberances, which the unicorn now used on herself as she continued to lick around the dildo moving into and out of the alicorn's sloppy wet pussy.

"Mmmh, you're very good, little Amethyst -- but do I see you pleasuring yourself at the same time? You are quite talented," the alicorn huffed through gasps as the pleasure she was receiving made it hard for her to concentrate on anything else. Amethyst simply moaned in response, eliciting yet another shudder of pleasure from the alicorn. "Aaah, that feels so nice! I haven't been spoiled like this in more than a thousand years!" she huffed, giggling a couple of times as she contemplated taking the unicorn as her own personal pleasure servant. The unicorn giggled as well, sending another ripple of pleasure through Nightmare's body. Amethyst continued to pleasure herself as she lapped up more pussy juice but then another idea struck her. She pulled back, pulling the dildo out of the alicorn's pussy.

"What did you stop for?" Nightmare asked, her voice tinged with anger and disappointment.

"I have something else in mind," Amethyst responded, flashing a wicked grin, then producing a very long double-ended dildo, then a second one which was slightly thinner but just as long. "Prepare your diddly-hole, shit's about to go down!" she laughed. The alicorn flashed a worried look, but saw the two dildos and a sly smile worked its way across her features.

"Are you planning to do what I think you're about to do?" she asked, her smile widening. Thoughts of intense physical pleasure ran through her mind, a strand of drool leaking from the corner of her mouth. Amethyst responded by showing an even bigger grin and nodding her head, and licking her lips lasciviously as she contemplated the new task ahead.

Meanwhile, back in Ponyville...

Twilight had galloped back to her library to figure out the next course of action before being confronted by Applejack and Rainbow Dash. After explaining the situation, they asked about Amethyst, to which Twilight had simply stated that she had met the purple unicorn in Canterlot and that she was nothing more than an acquaintance. The group decided upon traveling through the Everfree Forest to track down the Elements of Harmony to banish the Nightmare. Along the way, they encountered no resistance, as the alicorn's attention had been completely consumed with receiving pleasure at the hooves of said purple unicorn mare.

Back in the Castle of the Royal Pony Sisters

"Mmmm, that feels nice," the alicorn gasped as the unicorn was busy bumping her hindquarters against the larger pony's shapely ass. The two dildos moved easily back and forth as the two continued to bump their asses against each other, the lewd sounds of squishing and wetness dripping down their legs indicating the intensity of the pleasure each was receiving.

"Aaah! Aaah! Aaah!" Amethyst gasped as the physical pleasure threatened to overcome her. Her vision was tunneling, her body stiffening as she felt another climax approaching. The dark alicorn was likewise gasping as she was experiencing the most intense pleasure she had received in more than a thousand years. The two sped up their movements, their hindquarters slapping against each other with obscene yet erotic slapping noises, liquid dripping onto the floor behind them as they continued to bump their butts against each other's.

The dark alicorn gave a long, low, and yet very loud moan of satisfaction as her body trembled with the force of her climax. Amethyst likewise trembled and shook, the intensity of her orgasm so strong she screwed her eyes shut and nearly screamed in pleasure. It took a few moments for the two to recover some stamina, but they laid beside each other, the alicorn smiling in approval at the purple unicorn mare.

"Oooh, you're quite good, Amethyst," she cooed softly. She lazily stroked the unicorn's chest with a hoof, feeling the softness of her fur.

"Mmmmh, best climax yet," Amethyst responded huskily as she tried to cool down from exertion. She turned her full attention to the alicorn, noting the fact that they were now gazing into each other's eyes. Amethyst seemed transfixed in a hypnotic state as Nightmare Moon's cat-like eyes bored through the unicorn. Amethyst sighed softly and ran a hoof up and down the alicorn's chest.

"Amethyst, I am pleased by your actions," she stated softly, though her voice had a regal, almost commanding tone to it. "Please tell me you have some more energy left in you so we can continue with the pleasure," she added, almost pleadingly.

"Mmmmmmh, give me a few moments and we can return to what we were doing earlier," the unicorn replied, still laying on her back and admiring the alicorn's beauty.

Said alicorn giggled, the infectious laughter spreading to the unicorn. The two of them gazed lovingly into each other's eyes for a brief moment before they resumed their earlier activity of bouncing their hind-quarters against each other.

*Meanwhile, back in the Everfree Forest*

"Twilight, Darling, I don't understand why we're here!" Rarity groaned in disgust. "Trudging through all that muck has made my hooves dirty!"

"Look, Rarity, we're trying to get the Elements of Harmony! We can't defeat Nightmare Moon without them!" Twilight responded angrily.

"Um, girls, it's getting really late, and I have my animal friends to take care of -- is it okay if I head back home? I need to get some sleep," Fluttershy complained, her voice squeaking in the very still air.

"Girls, Ah oughta be headin' back t' the farm, we've wasted enough time here as it is," Applejack added as she let a large yawn escape her lips.

"Twiley, it's been really fun hanging out with you, but Flutters, Rares, and AJ are right -- we need to get ready for tomorrow! Tomorrow's another party!" Pinkie chirped, bounding around the whole group, a very wide grin on her face.

Rainbow Dash also yawned, sighed, and simply flew off in search of her home. She didn't feel the need to add any further to the discussion.

"Wait! What about the Elements of Harmony?" Twilight shouted at the retreating ponies, each of whom had their own lives to deal with. The librarian exhaled loudly in resentment, steeled herself, and trotted back home. "Ah, to Tartarus with it! Princess Celestia will have to deal with this one!"
