Bi-Light Sparkle

Bi-Light Sparkle

Twilight Sparkle had always been Celestia's favorite student, Princess Luna however had a different opinion of the word. The princess of the night had called Twilight to her Royal Lunar Palace for secret magic lessons. Princess Luna told Twilight to come alone, she couldn't resist. Galloping through the heavy rainstorm, Twilight pushed her way through the forces of nature toward the old palace. The inside of the palace was dark, Twilight couldn't see her hoof in front of her face. Drops of water slowly dripped from the saturated-purple mare, creating a puddle on the floor. Unclipping her saddlebags she levitated them to a corner to dry.

"Princess Luna?" Twilight called out nervously.

The huge wooden doors slammed behind Twilight causing her to jump in excitement.

"Twilight Sparkle. We are happy that you have decided to accept our gracious offer and humble us with your presence. You shall not be disappointed!" The disembodied voice called out in the traditional royal Canterlot fashion.

"Our sister, the great Celestia, ruler of the sun would be happy to see some of your magical talents wither away. However, we plan to teach you all that we have learned in our thousand years of exile!" Her voice boomed through the long abandoned palace walls.

A bolt of lightning flashed, revealing Nightmare Moon standing at the bottom of a huge staircase only a few feet in front of Twilight. Twilight jumped. Nightmare Moon had taken off her armor; Her fur was wet, revealing the glistening curves of the seductive princess of the night. Twilight felt herself also getting wet in different ways as the flashes of light each let Twilight glimpse more of the bare dark fur of Nightmare Moon.

"Twilight Sparkle. You lack the required experience to please us, so we must teach you!" Nightmare moon boomed, although she was standing right next to Twilight.

Twilight stood still; frozen in a mix of lust and terror, she couldn't move.

"Please you?" Twilight asked feeling her face starting to slightly burn in a heated blush.

Twilight was glad that it was too dark for Nightmare Moon to see cherry-red cheeks.

Twilight Sparkle felt a rush of excitement when Nightmare Moon's horn started to glow with a strange aura. The faint light crept outward into the darkness revealing more curves on Nightmare Moon's body than Twilight had ever seen. Twilight gazed at the dark princess, she felt a strange sensation overcome her. A magical chain quickly tied Twilight's front hooves together before dangling her in the center of the room, embedding one end of it's self into the ceiling. Two more magical chains tied each hind leg, spreading Twilight open for Nightmare Moon. Twilight felt herself fully moist now, anxiously she watched as Nightmare Moon trotted in a circle around her dangling body.

"Wh-What are you going to do to m-me?" Twilight gulped as the words nervously left her mouth.

"We shall show you the true meaning of pleasure! Twilight Sparkle." Nightmare moon revealed.

Nightmare Moon focused; The faint light that glimmered from her horn flashed a bit brighter as a magical whip appeared. Nightmare Moon twirled the whip around in the air, the room filled with a loud crack. Nightmare Moon wore a dark smile on her face. Twilight watched Nightmare Moon dance around her with sexual desire in her eyes. Twilight had a terrified expression.

"Oh no... not the whip, anything but the whip." Twilight said in a sarcastic voice. Excitement fought it's way through the fake terror Twilight tried to wear as a mask.

Nightmare Moon walked close to the bound body of Twilight Sparkle, the purple unicorn could feel the dark seductress' breath on her skin as Nightmare Moon leaned in toward the unicorn gently taking one of her nipples into her mouth. Nightmare Moon's tongue caressed Twilight's sensitive nipple causing it to become firm. As the dark alicorn felt the sensitive area swell under the pleasure of her moist tongue, she gently bit it. Twilight let out a gentle moan as the pain and pleasure mixed creating a more intense sensation.

"Mmm!" Twilight moaned.

Nightmare Moon stopped. Quickly raising the magical whip, she let it Twirl in the air again. This time it snapped onto Twilight's bare flank. The crack filled the air as the pain shot through Twilight's haunches. A red welt started to form on her bare flesh as a small singular tear forced it's way down the purple unicorn's cheek. Nightmare Moon walked close to Twilight again. Twilight turned her head as the whip wielding mistress tried to nuzzle her head against Twilight's.

"Oh! Don't be like that Twilie! We're just having a little fun." Princess Luna said in a softer voice than her counterpart.

Princess Luna tightened the chains, spreading Twilight's legs more. The much more timid Princess eased Twilight's anger.

"It's alright, you'll like this!" Luna said as she eased her way into position between Twilight's tightly tied legs. Chains securely attached either leg to opposing walls.

Luna gently extended her pink tongue, the soft wet texture felt wonderful as it contacted Twilight's clit, gently imparting Luna's secret trove of sexual knowledge to her less experienced purple-apprentice. Twilight felt rushes of extreme satisfaction besiege her body in a flurry of intensifying magnitude as she drew close to orgasm. Twilight's juices filled Luna's mouth, coating her tongue in the purple unicorn's pleasurable flavor. The environment of the room quickly changed as Luna shifted back into Nightmare Moon while a flash of lightning forked across the sky outside. Focusing her magic more now, the consistent light source that dimly light the room from Luna's horn became slightly brighter. Overlaid on top of where her horn should be, Twilight saw a very familiar stallion-only body part flash into existence. Nightmare Moon lowered her head to horn fuck Twilight Sparkle.

Feeling the dark princess' newfound endowment quickly fill her, Twilight could not hold back the moans that rang out, filling the Lunar Palace. Nightmare Moon spent years mastering spells of sexual desires, she could feel every inch of herself enter Twilight as if she were a stallion. The tight unicorn made the princess of the night moist in her haunches. As the tip of her erotic horn went deep inside Twilight Sparkle, Nightmare Moon started moaning. Twilight cried out to match her as she let Nightmare Moon have her way. Twilight Sparkle now felt the chains that held her captive loosen. She looked up to see Princess Luna smiling down at her, her horn normal again. Twilight was the first to talk.

"Wow!" Twilight cried."That was........The best one yet!"

"You get better at roleplay every time Twilight! But there is another reason I called you here." Princess Luna exclaimed as she winked at Twilight.

Levitating a small saddlebag with a ridiculous amount of diamonds on the outside from it's hidden place behind the staircase, Luna quickly opened the top. A large black tome floated from the contents over to Twilight Sparkle.

"Here, I want you to have this, It is just a little book written by Nightmare Moon I think they call her." Luna said with a gleeful expression on her face.

Twilight's eyes lit up, before she could speak Luna morphed back into Nightmare Moon

"Twilight Sparkle! You shall learn these magic spells to please us!" She thundered inside the stone castle.

Twilight Sparkle looked at the book. It was a large black tome with golden inscription, hoof written by Luna. Levitating her saddlebags from the corner, Twilight gently placed the treasure inside. Looking back up at Nightmare Moon, Twilight smiled.

"Oh, don't worry! I'm a quick study!" She proudly stated.

After several moments Nightmare Moon flew out of the castle to attend to her royal duties, feeling refreshed after her meeting with Twilight. Twilight made her way back toward Ponyville after the storm outside began to let up.

Twilight studied the book the next day with unwavering dedication, several spells had been easy for the magic inclined unicorn to understand. She practiced whenever she got time alone, getting good very fast. Some of the spells however, if not most required two ponies to fully attempt. The book was a vast collection of erotic bonding techniques coupled with penetration and conjuring spells. Not wanting to disappoint her dark mistress, Twilight needed to find a mare to help her and she knew exactly who to turn to. Gathering her saddlebags, Twilight slipped the treasured novel into them before closing the top with a click. Rarity had invited Twilight to a sleepover earlier that week. Later tonight was the night that Twilight was meant to spend the night at Carousel Boutique. Twilight had always known that Rarity was bisexual, after all, Rarity had not tried to hide it all those times staring at her haunches in the spa and fondling her flanks when she was preparing a dress. Twilight thought Rarity had all the right curves too, she just never found herself able to tell her. Luckily, Rarity had beat her to it a few days earlier.

A Few Nights Earlier

A few nights ago, Rarity had come to Twilight's house in Ponyville library late at night wearing a tiny black dress. Rarity looked splendid as she stepped inside the hollowed out tree. Intentionally brushing her flank against Twilight, Rarity let out a giggle. Twilight shut the door, turning around Twilight saw Rarity standing near the center of the room; She had let her hair down. One of the straps on her dress fell from her shoulder as Twilight turned, She knew Rarity had done it on purpose. Without saying anything, Twilight approached Rarity. Rarity stuck a pose that made the purple unicorn moist with excitement.

"Twilight?" Rarity asked. "Do you..... Want to come see me on the full moon?" Rarity's white face easily showed when she was blushing.

Twilight was not expecting the question.

"I uhhhh...I" Twilight stuttered.

"It's fine if you don't want to darling." Rarity said. She looked slightly disappointed. "But you know you make me wet." She winked at Twilight.

"No! I mean.... Yes! " Twilight cried. "Yes, I will come to spend the night with you Rarity." Twilight felt moist at the thought of what they would do alone together.

Back in Present Day

Twilight Sparkle trotted down the bustling street of Ponyville. All types of ponies frolicked in a captivating palette of swirling hues. Chatting and going about their daily lives, most of the ponies paid no attention to the knowledgeable-purple unicorn. The sweet smell of cupcakes filled the air as she cantered past Sugar Cube Corner. Pinkie Pie was hard at work making her special treats with Mr. and Mrs. Cake. The sky was clear, Celestia’s sun beamed unhindered golden light down on the pastel landscape. Twilight Sparkle thought to herself how beautiful the summer sun was, shimmering down on the rows of flowers that the earth ponies had planted alongside the road. Rainbow Dash and her weather team had cleared the sky, it was a blue sea without a hint of puffy-white obstruction. Later that night, the full moon would shine through the crystal clear sky bathing Ponyville in it's eerie aura of Luna's cascading light. Twilight trotted a while longer coming to a rest in front of Carousel Boutique. Opening the door, Twilight stepped inside the dressmakers shop. Bolts of cloth and bits of fabric littered the floors. Even though the mess was vast, the shop looked fashionable in the mid day sun. Stepping into one of the back rooms, Twilight called for Rarity.

“Rarity? It's Twilight. Are you here?”

“Back here darling.” The elegant voice of Rarity called out. “Just finishing up a few things for tonight. No peeking!” She added.

Stepping out of the work room, Rarity swayed her flanks as she came to greet Twilight. Shutting the door behind herself, Rarity glanced at her and winked. Twilight smiled, her face was washed over with a light red tint. Twilight’s horn glowed with a purple aura; Her saddlebags unclipped, as the top opened a thick black book levitated from inside. The cover of the book was aged, the title was hardly legible. “Uni-porn- Magic of the Night” was written in plain gold font.

“Here.” Twilight said. Smiling as Rarity took the book from her.

Rarity looked pleased, sparkles filled the white unicorn’s eyes as if she were looking at a pile of diamonds. The excitement took a moment to wear off before Rarity asked.

“Twilight dear. Where did you find this?”

Twilight struck a proud stance. Placing one hoof on her chest, raising her chin into the air as her eyes shut, she stated.

“Princess Luna. She gave it to me from her private collection! She said she had it memorized already so I could have it.”

Rarity quickly used her magic to levitate the sexual tome toward herself, opening it and skimming through the pages. Rarity’s ears perked, stopping on a page, a guilty smile started to form.

“Oh I can do this one.” She said peeking up from the pages at Twilight.

Twilight tried to peek over Rarity’s shoulder but the purple-maned unicorn snapped the book shut before Twilight could see.

“ No peeking. Remember?You will just have to wait… And…. See…” Rarity said winking. She shot a smile toward Twilight that moistened her lower regions.

Twilight blushed, smiling back she calmly stated.

“Oh! Well that’s okay! I learned a few new tricks from it already” Twilight's tail flicked toward Rarity as the words left her mouth.

With that, Twilight left the white-purple maned unicorn to finish whatever she had planned for the evening. Twilight intentionally swayed her flanks as she walked out of Carousel Boutique. Rarity's eyes followed her to the door. The white unicorn felt her gaze drawn toward Twilight's haunches. Soon after, she felt her face become warm; The elegant unicorn knew she was blushing.

SEVERAL HOURS LATER.

Twilight Sparkle paced the floor of the Ponyville library. Luna’s Moonlight shimmered through the windows with a silver sheen that stretched out, softly caressing the rows of knowledge. Twilight was anxious, she had been pacing since she got home from Carousel Boutique. Spike had told her to go to sleep several times; She made up excuses that "The full moon was too exciting to miss, so she couldn't sleep." Rarity had told her to come right at twelve o clock. At eleven fifty, Twilight made her way into the lunar-resplendence that bathed the streets of Ponyville. Spike watched her as she exited the door.

“Where’s she going…..” He quietly said to himself with interest in his voice.

Spike followed Twilight, he would duck behind bushes and buildings whenever the cautious unicorn glanced behind herself, she was acting weird Spike thought; Her actions fueled his curiosity even more. He managed to hold pursuit, staying out of sight as they traveled down the nighttime Ponyville road. Everypony was asleep by now, lights had been turned off in houses that lined the streets. Spike ducked behind Sugar Cube Corner as Twilight glanced behind herself again, she had almost spotted him. Spike's heart raced as Twilight scanned her surroundings. After a moment she continued down the main road. Spike let out a sigh of relief before quickly following behind.

Minutes later, the purple unicorn came to a place he was familiar with, Carousel Boutique. He silently went around the side of the building to peek in a window as Twilight entered the front door. Spike looked in the only window that light still shimmered from and saw Rarity in an erotic outfit. The black and white outfit was made so that it just barely covered Rarity’s sensual body parts. The french maid skirt plumed, Rarity’s masterfully styled tail streamed out from beneath. The white unicorn’s mouth held a feathered duster. She stood fashionably in the room, striking a pose as Twilight entered.

“Twilight! Darling! You’re finally here!” She cried, dropping the duster from her mouth.

Rarity turned to pick up the duster. She purposefully turned her rear to face Twilight before bending down. Sticking her flanks high in the air, her shortened skirt shifted slightly upward as she bent, revealing bare skin underneath. Twilight felt her eyes pulled toward the white unicorn’s inner haunches. She had no panties; her moist pussy glistened in the light. Spike felt his hemipene become firm as he watched Rarity flirting with Twilight. He wasn't jealous, actually this excited him.

Twilight walked toward the white unicorn. Still bending down, Rarity waved her rump at Twilight. The motion caused the sexy skirt to further reveal her excited wet regions.

“So.... What tricks do you have for me Twilight?” Rarity asked, a playful smile plastered on her face

Spike watched as Twilight levitated Rarity into the air. A purple magic rope wrapped itself around Rarity as she screamed in excitement and tried to struggle away. Twilight's magic however was inescapable, quickly binding Rarity tightly; Struggling only seemed to tighten the glowing purple bonds.

"Ooh! What now that you have me all tied up? I hope you don't do anything naughty!" She taunted.

Rarity bit her lip as Twilight used her magic to spread her legs further. The purple aura held Rarity frozen in place as several more snaking-purple tentacles appeared, tightening around Rarity. The groping snakes lightly squeezed her tender places, feeling moist as they slowly brushed across Rarity's fur. Some of the tentacles forced their way inside Rarity, into all holes as they jockied for position. A moment later, Twilight conjured a famous stallion into existence. Well... at least the one part of the stallion that the book had taught her how to create. Rarity felt an almost unbearable craving as Twilight teased her with the disembodied phantom. Only the tip of the purple mass brushed into Rarity's wet skin surrounding her sensitive regions. Twilight's tentacles pulled out of Rarity's damp holes dripping with juices, making room for their competition.

“Oh! I want it!” Rarity moaned to Twilight the moment she became un-gagged by the purple mistress's playful magic.

Twilight slid the stallion's endowment inside Rarity slowly for the first stroke. Wearing an approving grin on her face Twilight was amazed at the amount she could fit inside Rarity. Rarity gasped at the size of the purple-mass that filled her. Spike stood outside the window wide eyed, imagining the things he would do if he were in there. Twilight’s horn glowed as she leaned toward the white unicorn’s glistening fold. Purple light glinted off of moist areas on Rarity's elegant body. Twilight extended her soft-pink tongue until it contacted Rarity’s clit. The divine juices of the beautiful-white unicorn exploded on her taste buds. Twilight blissfully bestowed the white unicorn with waves of pleasure as her tongue caressed Rarity's sweet spot. Rarity's body relaxed, nearly paralyzed from the pleasure. Each flick of Twilight's tongue combined with the phantom appendage thrusting inside sent her close to orgasm.

Spike perched himself on a windowsill outside. As he was clopping to the scene inside Carousel Boutique he felt a strange sensation overcome him; He passed it off as excitement. He really wanted to be in there now more than anything he had ever wanted, feeling the urge to climb in the window would be too strong to resist at any moment, Spike closed his eyes. The windowsill’s wood cracked as Spike fell through the window, breaking glass on his way crashing through landing on the wooden floor inside. Twilight Sparkle’s magic dropped Rarity as her concentration broke; The sexy-white unicorn fell, landing on a pile of fabric uninjured. She was still panting from the pleasure Twilight had given her and hardly paid any attention at all. Twilight's eyes were wide, she stared at the purple and green dragon. Spike’s double penises were fully firm now. The windowsill had broken when Spike morphed, aging almost instantly. Spike was now bigger than either of the two ponies.

“Oooooh! What a naughty boy! Can't we have some fun with him Twilight?” Rarity pleaded, winking at the blushing-purple unicorn.

Twilight levitated the purple dragon, following Rarity into a nearby room. Spike barely fit through the doors as Twilight carried him along. Inside Rarity’s bedroom, Twilight dropped Spike on the bed. Bolts of fabric quickly floated from a pile nearby, tying Spike’s limbs to huge columns that adorned each corner of the massive piece of furniture. A twisting grin was on Spike's face as he felt himself throbbing in excitement.

“Hmmm. Lets make him want it more!” Twilight said with a curious tone in her voice.

“Well. We know he likes watching.” Rarity winked at Spike. “Lets give him a show!”

Twilight blushed, lightly positioning herself she lay on her back on Spike’s chest. The purple-wet unicorn spread her legs to show the dragon her excited hidden anatomy. Spike's eyes went wide seeing the juices glistenening in the bright moonlight that penetrated the windows from outside. Rarity positioned herself on top of the purple unicorn inverted from each other. Her mane lightly fell over her face as she lowered her head to taste Twilight’s flavorful-wet flower. Twilight conjured two more phantom-purple limbs; The same as the one she had made before. Spike watched as one of the long shafts slid inside Twilight. Rarity let out a light moan closing her eyes as one entered her before returning to pleasing Twilight. Spike stuck out his forked tongue, It was long now. Spike easily reached Twilight’s pink button, helping Rarity pleasure the moaning unicorn.

"Mmmmm! Spike! Rarity!" Twilight moaned. "That feels so good!"

Spike felt a surge rush through his lower member. Excitedly, Twilight saw them grow becoming twice the size they had been.The two horny unicorns now took positions on either side of Spike. They looked at each other, smiling before leaning in at the same speed each taking one part of him in their mouths. Spike’s throbbing manhood pushed deep in Twilight and Rarity’s throats. He felt Rarity stop sucking and double up with Twilight, the two unicorns looked at each other as they teamed up on the singular pole. Twilight and Rarity traded saliva, Spike's manhood lie between the two unicorns tongues that danced around the erect pole. Each taking their own part of Spike again, they felt his blood throb while hiding him deep in their throats.

Twilight and Rarity now switched positions again. Sitting on Spike the two were facing each other with their tongues in each others mouths. They bounced, happily riding Spike as he snaked inside their wet-warm caves. Twilight took all of Spike inside herself, she was smiling now. Bouncing enthusiastically on the dragon’s manhood, she moaned loudly.

"Oh! Celestia! Spike that feels So good!"

Rarity followed her lead, moaning each time she felt Spike's throbbing member slide to the back of her tight walls. Twilight and Rarity grew louder as Spike filled them more than they had expected, the dragon’s firm shafts assaulted the unicorns with increasing amounts of pleasure. The two unicorns could feel Spike pulse with each rush of blood that matched the dragons heart rate.The closer Spike got to finishing, the harder and bigger he felt himself become.

Twilight and Rarity’s tongues battled for positions in each other’s mouths. Spike watched the soft-pink muscles seem to dance as the two unicorns bounced in almost exact sync. Rarity pulled away, the pleasure was extremely intense; She was about to cum. Spike slid out of her twitching-wet hole, moments later she started squirting her orgasmic juices while moaning loudly. Clear thin liquid spilled from her onto the part of Spike she had been riding. Rarity quickly took Spike in her mouth again, tasting the delicious-warm juices that she had squirted a moment ago. Twilight bounced hard on one of Spike’s dual dragons, the other was deep in Rarity’s throat. Spike felt pressure build before he finally released his thick white liquid.

Twilight felt the warm cum fill her, slowly lifting off of Spike the thick jizz dribbled from Twilight’s battered hole. Cum filled Rarity’s mouth; She swallowed it before shoving Twilight down with her hooves, pleasuring the purple pony once again. Spike’s cum still ran slowly out from Twilight Sparkle, intense pleasure ripped through her as Rarity’s tongue flicked rapidly across her clit. Twilight Sparkle moaned, calling out Rarity’s name she felt herself orgasm. The clear-thin liquid was sweet on Rarity’s taste buds. Twilight blushed, pleasure was still on her face as they stood up together. Twilight kissed Rarity, tasting herself on the white unicorn’s muzzle she giggled. Spike shrunk back to baby dragon size mere seconds later. Falling out of the restraints Rarity had shackled him in, The purple and green dragon wore an ear to ear wicked grin.

“Soooooo…” He said twiddling his fingers. “ Ready to go again?”
