Nightmare Moon resurfaces. Sexual stuff ensues

Princess Luna has always had that little voice in the back of her mind, the voice of Nightmare Moon, whispering debaucherous things to her.

The princess has been able to control Nightmare Moon so far... but what happens when the darkness starts to resurface?

Clop. That is what happens.

First Resurgence

Luna rubbed a hoof through her mane idly, adjusting her position in the throne for the upteenth time. The throne had always bothered her; it was hard, and the cushion on it was barely comfortable. When she had to sit in it for night court for hours at a time, it was the single most uncomfortable thing ever.

Just a few more minutes, and it night court will be over, Luna reminded herself, giving an inward sigh.

A pony from way out west was beseeching for royal funding to expand the apple orchard at Appleloosa, as a recent tornado out that way had caused a large deficit in growing capacity.

Braeburn, she recalled. That was the pony’s name. A young stallion with a yellow body and a blond mane.

Do we really have to listening to this? Luna mused, before shaking her head to clear it and pushing the thoughts away.

“Have you any idea how much funding you will need?” Luna enquired.

Ugh, this is boring. We should just drag him into the royal bedchamber and have our way with him. Luna blinked several times, and then rubbed a hoof against her forehead. It was several seconds before she realised that she had missed what Braeburn was saying.

“Could you repeat that?” Luna asked politely.

“As ah was sayin’” Braeburn began.

Blah blah, fix this, fix that. Royal decree! Ugh. Must all ponies be so bland?! Luna scowled inwardly, before she took a deep, steadying breath and nodded to the farmpony. “Go to the royal accountant, he will have what you need.”

Braeburn bowed, and then turned away to find the royal accountant, leaving Luna alone with her thoughts. It had been several months since she had had the Nightmare Moon thoughts. They were so distinct from her normal thoughts: darker and nastier than usual. And sometimes, it was quite hard to ignore the supplications of her own dark desires.

That was to say, if they even were her own desires. Sometimes, what Nightmare Moon wanted was so far away from what she herself wanted that it almost disgusted her.

Luna slipped down off the throne, arching her back and stretching languidly, trying to work the stiffness out of her muscles. Her wings flared and quivered as she stretched them, and she adjusted her mane, before turning and heading for the library to check on Twilight Sparkle.

Twilight had been in the library for the entire night, excitedly researching something to do with dragons and their growth patterns. She had come up with a theory that a dragons growth rates were directly in proportion to their greed and the size of their hoards, and she was excitedly reading every book she could possibly find on the subject.

Pushing the library door open, Luna found Twilight laying on her stomach amidst a heaped fortress of books, neatly piled up all around the unicorn. Her nose was buried in a book, and she was skim-reading rapidly. Spike was nowhere to be found, likely asleep back at Twilight’s library.

“Twilight?” Luna asked, as she poked her nose through the doorway.

Twilight looked up, leaning her head around a book. “Hey Luna!” she said brightly.

“I see that your studying goes well. Would it not be best for you to sleep soon?” Luna suggested. Offer her a place in our bed. Nightmare Moon whispered in Luna’s mind.

“Oh, but I still have some books to go through!” Twilight complained, tapping a hoof against the top of a pile of books.

“It is near midnight,” Luna pointed out, sitting down on her haunches to one side of the young unicorn’s book pile. From her position, the alicorn had a rather good view of Twilight’s rump, and she found her eyes drawn towards it as the purple tail swirled back and forth. Look at that shapely rump. For a filly who spends all her time reading, she sure is well-built.

“Ahh... yeah, I really should get some sleep,” Twilight admitted, frowning deeply. “But just a few more paragraphs!”

Luna nodded in response, her head tilting to one side. Twilight was too absorbed in her book to pay much attention to Luna, which was fortuitous for the alicorn, because she found herself unable to look away from the unicorn’s rump. With every swish and swirl of the purple tail, the soft outer lips and the pink inner flesh of Twilight’s young, luscious pussy were revealed to the alicorn. Unconsciously, her wings fluttered, stiffening into the air, while her eyes narrowed eagerly.

“You could... stay in our room,” Luna suggested, before she could stop herself. Nightmare Moon’s voice was quiet in her mind, but very loud in the air, forcing Luna to say what the dark goddess wanted.

Twilight perked her ears up at that, and then looked back over her shoulder excitedly, her rump giving an unconscious wiggle. “Can I bring my books?!”

“Of course, Twilight,” Luna said with a gentle nod, jerking her head back towards the hallway.

A happy grin crossed the unicorn’s face as she picked up her pile of books with her magic, and then bounced into step behind Luna as the alicorn turned and began to lead her towards her own private quarters.

“All done with the night court?” Twilight asked cheerily.

“Indeed,” Luna said with a gentle nod. “Such a dreary, boring exercise.”

“I know I wouldn’t like to have your job,” Twilight said with a wrinkled nose.

“It has... advantages,” Luna said with a slow smile, looking sideways at the unicorn.

Twilight perked her ears upwards, oblivious. “Advantages?” she asked curiously.

“The work is boring, but the scenery is exemplary,” Luna explained with a sly grin.

Twilight blinked at that, staring up at the alicorn. “Scenery?” she asked, as Luna pushed open the doors to her personal quarters, “But you work inside the palace!”

Luna just gave a wry smile at the naive unicorn, as she stepped into the room and then closed the doors behind them.

“Scenery, yes,” Luna stated, pointing towards the bed. “You can put your books there.”

Mystified, Twilight turned and moved towards the bed, laying her books neatly across it.

Luna watched with narrowed eyes, her tail giving a slow flick and her wings flaring into the air, unable to keep her gaze from straying to the purple mare’s rump.

We could do more than just stare, you know... Nightmare Moon whispered enticingly into Luna’s mind.

Luna bit her lower lip, chewing on it helplessly for a long moment, casting her gaze left, and then right, shifting her weight from forehoof-to-forehoof furtively.

Nightmare Moon was an influence that Luna had been fighting against for so long. It was already second-nature to ignore the urgings of the dark princess whispering in the back of her mind. But with the tableau of Twilight’s rump right in front of her, it was impossible to resist.

“So why did you offer to let me stay here the night?” Twilight asked, turning around.

Twilight came nose-to-nose with Nightmare Moon, the larger alicorn leaning down to be more on the unicorn’s level.

“Why don’t you take a guess?” Nightmare Moon asked, her voice low and husky, blue eyes narrowed intently, lips stretching into a smile, revealing her fangs.

“U-uhm L-Luna?” Twilight asked nervously, taking a step back, her rump bumping into the bed, halting her movement.

Nightmare Moon took a step forwards, towards Twilight. “Luna isn’t here right now... You could leave a message,” she breathed huskily, her wings flaring into the air, stiffening.

Twilight turned sideways against the bed, stammering. “L-Luna, aheh... t-this is a good joke but y-you can stop now.”

Nightmare Moon shook her head slowly, eyes narrowing further. “Oh no, this is no joke,” she breathed with a sly grin, “We have been feeling... antsy of late. And we will have our satisfaction.”

The unicorn blinked up at the alicorn, her ears splaying back. “S-satisfaction?”

“A thousand years on the moon... and a further two years here, in Equestria,” Nightmare Moon breathed, beginning to pace back and forth in front of the unicorn in irritation. “So long have we gone without satisfaction, and we shall have it.”

Twilight shrank back again as Nightmare Moon advanced on her, the much larger alicorn pushing the unicorn up against the bed, before a quick heave of her shoulders pushed the librarian onto the bed, splaying her out on her back. Blue eyes narrowed slowly on the unicorn, and Nightmare Moon crawled up onto the bed with her, straddling the librarian with all four legs, staring down at her.

The unicorn flushed, her ears splaying backwards. “T-this has got to be a j-joke...”

“No joke,” Nightmare Moon breathed heatedly, swooping in and laying a heated, eager kiss against Twilight’s muzzle.

Twilight’s eyes went wide, and she shuddered helplessly against the forceful kiss, even as Nightmare Moon’s tongue pressed forth to rub and coil against her own in a lustful display.

The unicorn gave a helpless whimper, arching, her eyes widening further as a hoof suddenly pressed between her legs, grinding up against her, rubbing against her soft purple-furred outer lips.

Nightmare Moon rubbed her hoof back and forth slowly against the unicorn’s soft cunt, grinning down at her and kissing her all the more urgently, her wings flapping eagerly. The alicorn tilted her head a little further forwards, and their horns touched.

An electric jolt passed between them, and Twilight arched, stiffening under the alicorn with a gasp, her eyes wide and hindlegs wrapping around the hoof between them, squeezing at it helplessly.

Nightmare Moon grinned down at the unicorn, tilting her head back to disconnect their horns, halting the electric sensation and allowing the unicorn to relax. A low groan left the unicorn as she relaxed back, whimpering faintly.

“Enjoying yourself, Twilight?” Nightmare Moon asked with a sly grin, grinding her hoof between the unicorn’s legs all the more firmly.

Twilight shook her head shakily, panting for a moment, before closing her mouth and evening out her breathing. “P-princess L-Luna, stop!”

Nightmare Moon peered down at Twilight, her eyes narrowing, her flowing tail giving a slow, errant flick back and forth. A sly grin stretched across her muzzle, and she leaned down to nuzzle past Twilight’s muzzle so that she could whisper into her ear, “...No.”

The unicorn stiffened again as the hoof pressed between her legs all the harder, grinding up against her soft, pliable outer lips, rubbing against them with a maddening friction, making her whimper and stuff a hoof against her muzzle, her cheeks blazing with heat while she pushed her hoof down against the one between her legs, trying to stop the alicorn.

“Now now, Twilight,” Nightmare Moon breathed, grinning as she pinned Twilight’s hoof in place with her own, all the while grinding between her legs with the other. Grinning innocently, the alicorn brought her hoof up, showing it to the unicorn, letting her see the wetness glistening on it. Her grin turning mischievous, Nightmare Moon leaning in and swirled her tongue lewdly over the wet hoof, cleaning up the liquids with a sly smile.

Twilight watched with a mixture of fascination, squeamishness, and worry, her eyes wide, her breathing at a heavy pant.

“Now don’t squirm too much, Twilight,” Nightmare Moon murmured, grinning, her eyes narrowing slowly. “I’m going to make you scream.”

The unicorn stared at the alicorn, hoof still covering her mouth, trying to roll over and get away, but a single firm hoof held her in place. Nightmare Moon was so much larger than her, so much more powerful, both magically and physically, that it was pointless to try and get away.

With a grin, Nightmare Moon laid a trail of kisses down Twilight’s form, starting at her nose, moving onto her chin, her neck, the hollow of her throat, and then down over her sternum.

Twilight whimpered helplessly, lifting a hoof to try and grasp the enlongated black horn in the centre of Nightmare Moon’s forehead, trying to get her to stop.

Nightmare Moon just giggled, tugging her horn out of Twilight’s grasp, swirling her tongue firmly down over the unicorn’s stomach in an eager motion. one hoof came up to rest on the librarian’s stomach, while the other pressed against her inner thigh, splaying her open to the alicorn’s gaze. Nightmare Moon drew back, eyes narrowing as she inspected the unicorn’s exposed cunt properly for the first time. The hint of moisture, smeared across her entire groin by the firm hoof-rubbing, caused the area between her thighs to glisten with wetness, the soft, pliable outer lips looking plump and inviting. The hint of pink flesh between them beckoned to Nightmare Moon, and with a low growl, she leaned in to swirl her tongue heatedly against the unicorn’s sex.

Twilight flushed deeply, her hooves flying to her mouth with a gasp as she quivered and arched, a helpless squeak leaving her.

The alicorn grinned up at Twilight from under her helmet, blue eyes narrowing as she pressing her muzzle in firmly against the wet sex, swirling her tongue powerfully against the soft, pliable outer lips, spreading them with the pressure and allowing her velvet muscle to grind up against the slick, soft inner flesh.

The librarian squeaked again, her eyes clenching closed and the muscles of her stomach rippling visible. Nightmare Moon giggled muffledly against her, lifting a hoof to stroke across her rippling stomach, even as she delivering a heated flurry of firm licks against the soft cunt, causing more and more of the unicorn’s moisture to wet her lips.

With a low, lusty growl, Nightmare Moon lifted her mouth a fraction higher, closing her lips over the unicorn’s clit and suckling powerfully, even as her tongue dipped forth to rub and grind against the sensitive little button.

The unicorn writhed against the bed, throwing her head back and giving a heated cry of helpless delight, a sudden rapid rush of liquids spilling from her clenching, squeezing sex.

Nightmare Moon grinned up at the unicorn, slowly drawing back and licking her lips innocently, her eyes narrowing on the panting form of Twilight. “Finished already?” the dark goddess asked sweetly, rubbing her hoof across Twilight’s stomach. “How cute.”

Twilight shuddered, her face burning with embarrassment, stuttering breathlessly at the alicorn. “B-but I-I-”

Nightmare Moon crawled up Twilight’s form, grinning and licking down at her nose, the princess’s tongue smelling of Twilight’s own liquids.

“Shush, Twilight,” the dark goddess crooned, gently tracing a hoof down her form, and then giving a sly smile, drawing away and rolling onto her back. Nightmare Moon narrowed her eyes at the unicorn, spreading her hindlegs slowly, to reveal the soft pink sliver of flesh between them, highly visible amongst the black fur. “There are much better things you could do with that mouth.”

Twilight stared with wide eyes, her cheeks burning even hotter at the display. She bit her bottom lip, giving a whimper.

Nightmare Moon’s eyes narrowed slowly, and she snorted once, slipping a hoof down to rub between her thighs slowly, grinding against her aching cunt. “Come, Twilight. You would deny your goddess?”

“N-no b-but-”

“-Then cease your incessant talking and get to work!” Nightmare Moon growled, free hoof lashing out to grip the unicorn’s horn and tug her down until her nose numped up against the alicorn’s cunt.

Twilight flushed heavily, her ears splaying backwards, her nose showing a touch of Nightmare Moon’s liquids. “Y-you w-want me t-to lick?” she stammered nervously.

“Yes!” Nightmare Moon growled, her eyes flashing.

Twilight shuddered, and then closed her eyes, tentatively extending her tongue, until it came into contact with those soft, black-furred outer lips, tasting the princess for the first time.

“You are not taste testing a cake!” Nightmare Moon declared, gripping Twilight’s horn and grinding her hips towards the unicorn’s muzzle urgently. “Lick me!”

The unicorn tried to stammer an excuse up at the princess, before she quieted herself and stared at the alicorn’s sex for several long moment. Taking a deep, steadying inhale, Twilight leaned in close and let her lips contact the sweet-smelling sex in front of her, the scent instantly invading her senses as she opened her mouth tentatively and then swirled her tongue in a long stroke against the soft outer lips.

Nightmare Moon gave a low groan at that, hissing with her tongue clenched between her teeth. “Good girl!” she praised, still grinding her hips slowly against the unicorn’s muzzle. “Don’t lose focus now!”

Twilight nodded nervously, taking another deep inhale before giving another firm swirl of her tongue against the dark goddess’ cunt, gently working the velvet muscle up against the soft, pliable lips, feeling them give a little bit, allowing her tongue to sweep against the smooth, furless inner flesh.

With another shudder, the unicorn slipped in a little bit closer, pressing her lips all the more firmly against the dark-furred cunt in front of her, swirling her tongue firmly in against the soft inner flesh of the eager dark goddess.

Nightmare Moon growled heatedly, grinding her hips towards the swirling tongue, panting heatedly, one hoof supporting her weight behind her while the other gripped Twilight’s horn, helping hold her in place and also urging her to work harder against the alicorn.

Twilight panted, pulling back for a gasp of air, taking several long seconds before Nightmare Moon lost her patience and dragged the unicorn’s muzzle back between her thighs and buried her face in against her wet cunt, grinding her hips against the unicorn over and over again.

The unicorn took the opportunity to lap firmly against the alicorn’s quivering cunt. With a deep inhale to fortify herself, Twilight leaned up and clasped her lips over Nightmare Moon’s clit, suckling around it clumsily as Nightmare Moon had done to her mere minutes previously.

The alicorn tensed up, her entire form beginning to quiver as she mushed Twilight’s face against her quivering cunt in reflexive delight, the muscles in her stomach rippling visible under the taught flesh.

With a low cry of delight, the alicorn came, grinding against Twilight’s working tongue eagerly, quivering cunny spilling a rush of slick liquids across her face and lips again and again, coating the unicorn in the goddess’ rich scent.

After several long moments of bliss, the alicorn fell backwards, her limbs too shaky to support herself any more. A low groan of delight left her, and she arched out contentedly. “Good girl,” she whispered to Twilight, closing her eyes.

Twilight flushed, lifting a hoof to her muzzle to try and clean it off a little, her cheeks burning with heat at what just happened, looking from the passed-out goddess, to the moist cunt shamelessly exposed to her. The unicorn licked her lips helplessly, tasting Nightmare Moon’s distinctive flavour on them, and then carefully pulling herself to the other side of the bed, laying herself out on her side.

Nightmare Moon rolled over, and pulled the unicorn against her with a grunt. Twilight flushed deeply, trying to squirm free, only to find herself trapped in place by the alicorn’s powerful forehooves. Flushing deeply, the unicorn wiggled back against Nightmare Moon to get comfortable, before closing her eyes to get some rest as well, her studying forgotten.
