Sinful Twilight An adult pony story by Sen Grisane

ᐅ At night in the treehouse… ᐊ

Twilight Sparkle vehemently tossed and turned in her bed. As much as she tried to find entrance into Luna's domain, a restful sleep was denied to her.
With heavy hooves she got out of bed and trotted down to the kitchen, dampening her steps with a little bit of magic to not wake Spike. How envious she was of him as she passed by his little bed. He was sound asleep, probably having adventures in dreamland.
"A warm milk will help me fall asleep." She muttered, trying to convince herself of her own words. But this was already the third night where she could not find any rest.

There was something burning inside of her. A need, a desire she had never felt before. At first she thought she was just horny. And it helped for a little while, whenever she quenched the fire in her loins with a facsimile of a male pony's genitals.
In preparation for today's night she had brought herself to climax three times. Yet, here she was, in the kitchen a glass of warm milk at her lips, dead tired and wide awake.

After finishing the glass she headed to bed once more, with nary a hope that this time it would work.
Not really thinking about it, she stretched her wings and knocked over the milk glass. Luckily there was nothing to spill. "Shoot!" She cussed under her breath. Twilight was still new to having wings and was often not aware how much reach she had with them. She thought back to her transformation and shuddered. Such a big moment, but also so much responsibility.
Then an idea hit her! "Wait! Waitwaitwait! This might be an alicorn thing! Perhaps Princess Celestia knows more about this."

Under normal circumstances writing about something so personal and intimate would have been difficult for the introverted alicorn. But currently she was running on only a handful of brain cells and none of them were responsible for feeling embarrassment.
She quickly jotted down her problem, with a plethora of spelling errors, and hovered the scroll above Spike's mouth. Twilight knew the dragon all too well and a little tickle on his belly was all it took for him to belch a flame big enough to send the scroll on its way.

ᐅ The next morning… ᐊ

"Ringring! Ringring!"
Twilight stumbled out of her bed almost as if she was drunk at the sound of the door bell. More tumbling than trotting down the stairs, she made her way to the main door, when she heard "Ringring!" once more.
"I'm coming!" she shouted, still wondering why her door bell sounded off… did she have a door bell?
As she opened the door, a big grin on an awfully familiar pink face greeted her with "Ringring!"

"Pinkie! What are you doing here?" Twilight said surprised, as Pinkie Pie entered with a big bounce. "Princess Celestia sent me. Big Mac not doing it for you any more eh?"
"PINKIE!" Twilight said blushing intensely. As if buying sex toys from her wasn't awkward enough, the pink pony had named all the toys she made and sold after friends and family. "Not so loud! And why in Celestia's name did she contact you?"

Pinkie Pie gave Twilight a pat on the head and said "Becaaa-ause I provide ponies with much more than high quality toys. I can also provide…" she leans forward and whispers into Twilight's ear "the real deal."
"WHAT!? You… how… when?" stuttered the purple equine.
"Oh for a long time really. It's kind of a family business. Teeheehee!"
"And why would… the real deal… help me with my problem? I don't see the difference. It's just a matter of… proper stimulation."

"Oh Twili. Only you could equal a dead piece of wood…" Pinkie told with increasing intensity while walking towards Twilight who was slowly backed up to evade her hot breath "...with a pulsing, moist, glistening, throbbing…. COCK."
After literally talking her friend into a corner she bounced back and produced a piece of paper from behind her. "Princess Celestia figured you wouldn't be satisfied without a big, wordy explanation though, so she gave me this. Eh-erm."
"Donning a pair of glasses out of nowhere she began to read: Dear Twilight. I don't need to tell you that the transformation you went through was a big change. However the changes your body went through, and still does, go far beyond what you can fathom at the moment. You didn't simply grow a pair of wings. You now encompass all of ponyhood. This means you now have all aspects of all the pony species.
All the little ponies have magic, not just the ones with horns. Pegasus’ ponies innate magic allows them to fly much better than their wing size would normally allow and is the reason they can effortlessly walk on clouds.
In earth ponies their magic fuels their bodies directly, enhancing strength, stamina, resilience as well as…" Pinkie paused for dramatic effect and to wiggle her eyebrows "...their libido."

One could see the purple pony processing the information as her face changed with each new realization. "So I am now part unicorn, part pegasus and part earth pony. And earth pony's libido is fueled by their innate magic. And since my pool of innate magic is much larger than an average pony's, that means my libido is also enhanced that much more."
"Yup. Guessed right on the first try. Which is good because we gotta get to the actual porn part of this story or the reader will blow his load to boring exposition."
"What?" Twilight said confused.
"Oh nothing." Pinkie said then added in a voice so low only the readers could 'hear' it "If you came already leave a comment. I wanna know you have a boner for porn plot. Also I wanna know if any girls are reading this. Tell me if you do if you dare!"

"But that still doesn't explain why I need a real… penis to fix this. Why doesn't masturbation help at all with my urges?"
"Well..." Pinkie took off her glasses and muses "...I guess because as alicorn you are not only an amalgamation of all the ponies on a physical level but also on a spiritual level." Pinkie Pie grabbed Twilight's cheeks with her hooves and screamed into her face. "You are a fucking goddess now and a goddess might need something more than some carved piece of wood to get her spirit pussy into spasm heaven!"
After letting go of the startled alicorn she added "But you know. Just a guess."

"Whut's with all the screaming?" A drowsy Spike asks coming down from above.
"Oh nothing! Pinkie Pie just wanted me to help her with.. erm."
"Pies. She's helping me with some pies. Cream pies." The energetic earth pony helped her friend out.
"Oh that sounds great. Can I come?" Spike says enthusiastically whipping his tail back and forth."
"Sorry little Spikey. A lot of people will be cumming already." Pinkie said with a wink.
"Pinkie!" Twilight said under breath.
"Can I at least get a cream pie once you're done?"
"Oh you'll have to ask Twiliy of you can have a lick of her-"
"NO. Pinkie we leave. NOW! Spike clean the library until I'm back."
"Awww."
The alicorn stormed out the house and dragged the pink pony along with her magic.
"Bye bye Spikey Wikey."

ᐅ Later in the basement of Sugarcube Corner... ᐊ

Twilight had been in the basement of the bakery before but knowing that it houses the entrance to some kind of brothel made every dark corner look ominous.
Pinkie led the way to the back of the room. There she stood next to a stack of bags of flour and gave the wall next to it a kick with a hoof. The whole stack of flour pivoted to the side and revealed a tunnel.
"Welcome to Casa del Pecadooo! But to get there we need to take the Tùnel del Trama!"

As she walked down the dimly lit tunnel, doubt crept back into Twilight's mind. "I dunno. This feels weird. What if I know the pony who…"
"Oh you definitely know him."
"What! I couldn't. I can't! How could I look him in the eyes afterwards?"
"Simple silly. He's gonna wear a blindfold."
"But I'd still know. Can I have a blindfold too?"
"Of course. It'll be like a blind date... just actually blind with lots more fucking."
"Sigh. Pinkie do you always have to be so-"
"Vulgar? Raunchy? Perverted?"
"DIRECT! I meant direct!"
"Don't be such a spoilsport. Let me have some fun… Oh, come on. Don't make such a pouty face. You're here to have fun too. Relax! I have been doing this for years. Celestia, Luna and Cadence are all regulars here."
"C-cadance comes here? But she's-"
"Sure, she visits less now that Shining Armor plows her regularly with that giant …erm…, but she's still got a few itches she needs scratched now and then."
"Wow. I don't know what to say. I'd have never guessed."

The tunnel ended in stairs leading back to the surface. Soft light poured through the rectangular opening. Nervously Twilight poked her head out and found herself inside a cozy cottage in the woods. The room had two doors covered by heavy, red curtains and a third that, presumably, led outside.
"This way. Your lover is already prepared and waiting for you."
Pinkie Pie led her through the left door into a hallway filled with many more curtained entrances.
As they passed by, she could hear someone talking.

"A budding stud, one wild ride
So full of blood, spreading me wide.
Oh you are a keeper!
Hurry! Push it deeper!"

Blushing she hurried along and bumped into Pinkie's rear end who had suddenly stopped. "Oh sorry Twilight. My ass is already booked today."
"Oh I didn't mean-"
"I know Silly. I'm just pulling your hooves. We are here. Are you ready to have your love cave painted white?"
Twilight wanted to voice a complaint but resigned to a sigh. "Sure?"
"You don't sound very sure."
"I'm about to sleep with a stallion I don't know… or do know but don't want to know, in a secret love hotel in the middle of the forest. Of course I'm not sure."
"Well that can be helped!" Pinkie said, enthusiastic as always and slid a blindfold over Twilight's eyes.
"Wait what? Oh!" the alicorn stuttered.
"Iiiiin you go! Teehee." Pinkie laughed as she pushed Twilight into the room.

"I'mnotreadyI'mnotreadyI'mnotready!" she squeaked but it was too late. Twilight was alone in a room with her mystery lover. The air was heavy with musk and with every breath, the magical pony could feel her body heating up. While not the most experienced of lovers the alicorn had had male company before, but today felt so very different. She felt herself drawn to the center of the room like a moth to a flame.

Then her front hoof bumped against something soft. A bed! Her ears picked up deep breaths drawn in through nostrils.
"H-hello." she muttered.
A gargled "Mmmrgl!" was her only answer.
"Was the pony gagged?" She thought to herself and felt around a bit with her hooves. It was weird. Her male companion was sort of fused into the bed. Only the snout and the cock protruded from it.
"Was the stallion into bondage? Or did Pinkie arrange it like this, so I’d have minimal skin contact?" Twilight wondered.

But it soon became too hard to continue that train of thought as every part of her body tried hard to get laid. The only thing still resisting was her brain and that was losing the battle fast. Before she even realised, she had put the raging pony boner in her mouth and slid her head down until her snout bumped into his belly. Were she still thinking rationally, she would have found it odd that she could deep throat a whole stallion's shaft with such ease. But with every moment her instinct took over more and more.

It felt different from any sex she had before. Just having the taste of a stallion's shaft on her tongue and the musk of an eager male in her nostrils, it made any lust she had felt before pale in comparison. Right now there was only her and him. Nothing else mattered.
Suddenly the undersized shaft twitched and throbbed in her mouth and the whole body of her lover trembled. "An orgasm?" she wonders through the fog of lust "So quick? Can’t be. There's no ejaculate."
It mattered not. The cock was still hard.

With a drawn out moan Twilight let the shaft slip out of her mouth. Now wet with saliva she felt it was ready to mount. With shakey hooves she climbed on the bed and got on top of the equine member. As the flared tip kissed her labia, she couldn't suppress a squeal. "How does this feel so good? It's not even in yet!"
She never needed anything more than this dick at this moment. Another loud moan filled the room as the alicorn sank down on the shaft. All of it fit inside her with ease.

Fireworks filled the magical pony's brain. She froze on place, the dick deep inside her pussy, and just enjoyed the rush of energy that emanated from her lower body. "So… intense… I… can't…"
All thought was blown away by an orgasm unlike any she had before. She was a teacup trying to capture a waterfall. All the energy just spilled out of her and manifested as random magic effects around her. But she wouldn't have noticed even without her blindfold. Twilight screamed on the top of her lungs wanting to tell of everyone of her pleasure.

Without her realizing, her hips began to move. Even though the first climax was still echoing through her, she could feel every thrust building up a new orgasm.
There was little she could do as, in addition to her mind, her body was now on autopilot as well. She melted into a sea of ecstasy. A lighthouse on a big rock was the only solid structure and every time a wave crashed against the cliffs another climax made her scream with lust.
Time passed. Did time pass? What was time? The mere concept of anything but this moment became alien to the pony.

But nothing can last forever and eventually the sea calmed. One by one the sensations came back to Twilight. A far away voice called her name.
"Twili! Twili! Is everything alright? Speak to me!"
"Wharubinkie?" she replied, still not in full control of her mouth.
The alicorn is lifted up, something hard and warm slid out her cooch and she was dragged out of the room. Moments later she was blinded by light as her blindfold was removed.

"Holy moly Twili! That was some intense ride. Your magic went crazy! Frankly I'm surprised this building is still standing. How was it? Must have been amazing! I have never seen anything like it!..." Pinkie Pie chatted at high speed and soon her words faded into background noise.
Confused Twilight looked around. She was in the hallway, but the dark wood from before was stained with all the colors of the rainbow. The heavy curtains fluttered in a non-existent wind, while a ringing noise echoed through the corridor. A few ponies poked their heads out to see what was going on. Luckily they couldn't see much as the air was filled with golden sparkles.

"Oh Celestia!" was all Twilight muttered trying hard not to fall asleep. "Not right here, in the hall, where everyone can see me" she thought.
Leaning heavily on the pink pony she crawled out of sight of the curious guests of this establishment and left a trail of her pussy juices behind.
"Cleanup in hallway 2!" Pinkie yelled and pushed her friend into an unoccupied room.
There were many things she wanted to ask, but was soon as she lay down on the fresh bed her lights went out. The many sleepless nights and the intense ride were too much for her.

ᐅ Finally a good night's rest… ᐊ

Twilight awoke in her own bed and by the smell of her fur someone had given her a shower. Something she felt both thankful for and embarrassed about.
She was not sure if she felt ready to confront reality again after all that happened, but she could hear voices from downstairs. She stared at the ceiling for a few minutes mustering the courage to get out of bed.

“Sigh. C’mon. It’s nothing strange. It was just copulation for recreational purposes. All the other Princesses have done it. Nothing to be ashamed about…”
She rolled out of bed onto her hooves, took a deep breath “Huff!” and made her way downstairs. To her surprise she felt light as a feather and brimming with energy. Was it like that for all earth ponies? She caught herself falling into a dance like trot after only a few steps.

As she reached the ground floor she was greeted by “My faithful student!” “Twilight!” “Princess!” All 3 alicorns were present and enjoying a hearty breakfast.
“Celestia! Cadence! Luna! Good morning. You are here. You’re... all here.” with an embarrassed smile replied to the others.
“Of course we are here. We want to know what happened. What we heard made us… curious.” Luna said with a mischievous smile.
“I’m not sure we should talk about this now. Spike might hear-”
“Don’t worry. We sent him on an errant. It’s just us” - “AND ME!”

Pinkie Pie burst from into the dining room, balancing several plates on her head and rear. She parked them all in front of Twilight. On the plates pancakes were stacked so high she could hide from view for a moment.
“Since you like it hot and steamy, I prepared them fresh. Oh and of course! Let’s not forget the special sauce!” With swift hooves the pink pony pulled out a bottle and squeezed whipped cream all over the pancakes while playfully moaning “Ooooh noooo. So much saaaaauce!”
While Twilight turned red, half from anger, half from embarrassment the Princesses laughed and snickered. The magical pony was desperately trying to think of a way to weasel out of this when a loud growl interrupted her thoughts. It was her stomach. The delicious smell woke it up and protested its emptiness. “Well, as long as I’m eating, I don’t have to answer their questions.” she thought and shoved a whole pancake in her snout, quickly followed by another and another.

The others ponies let her enjoy the snacks for now and continued with some small talk until everything was gone.
Cadence was the first to address Twilight this time “And? Feeling better?”
Twilight nodded, still chewing on the last bites of pancake.
“Then please tell us how it went. I know it is a delicate subject that is fairly new to you, but… well... you see. Sigh. There are certain experiences that are unique to you… and me and Celestia and Luna. And even though it might be uncomfortable, it would be helpful if you would talk about it with us, since we’re the ones that can relate and help out if… well, y’know.”

Twilight chewed those last bites really carefully and then reached for the milk glass for a big gulp.
“Perhaps it would help if we started with our first experience?” Cadence asked.
Twilight nodded. Anything to delay this.
So Cadence continued: “Okay so my first time as an alicorn was a lot less wild than yours, at least from what I have heard. Celestia arranged an intimate meeting with a lovely little colt in the hedge maze in Canterlot.”
“Little colt?” Twilight muttered surprised.
“Oh! Er… I mean, you know. Like a dainty stallion, overall small but big where it counted. And so full of spunk! We made love all night. Every thrust felt like my ass was set on fire… in a good way.”
Luna interjected “Wait. You went anal only on the first time?”
Now even Luna blushed for a moment: “Of course. I saved my pussy for Shining Armor. Hmpf! Anyway, after that we met almost daily for a while. Doing it in all kinds of kinky places, we were almost caught a few times.”
“Almost?” Celestia laughed. “Oh please. Everyone knew what you were doing. Your screams carried far and wide.”

Twilight was no longer intense red in the face, but hearing about her foal sitter’s sexual exploits kept her cheeks a rosy red. When Cadence was finished she looked over to Princess Celestia, hoping for a few more minutes of delay.
“Oh my turn now, hm? Okay then. Please bear in mind that this happened thousands of years ago. The kingdom was only formed a few months ago and the ponies back then were a lot less modest. Sex would often happen in public, with no regards for onlookers. Sometimes crowds formed which turned into orgies on a few occasions.
As for me, well we had a whole kingdom to proliferate. So I joined as often as I could. I don’t even remember when or with whom my first time was. Thinking back I only remember being involved with more than one pony. My usual routine was to visit a house, enjoy some intimate moments with the occupants and move on to the next. I must have birthed hundreds of foals in those first years.”
Celestia talked about her experiences as if it was a weather report, calm, collected and not the slightest bit red.

Then Luna spoke: “Oh sister. Today’s ponies can be so shy. Back then I only had to land in the middle of a village, announce my presence and they all came running eager to get a piece of royal ass. I tried that once after I was freed from the moon and everyone stared at me like I was crazy!”
Cadence and Celestia both giggled, while Twilight tried to push away the mental images pestering her mind.
Luna continued “My favorite was being in the middle of a huge fuck pile. Dicks everywhere. In my ass, my cunt, my mouth. Often more than one per hole.”
“Oh I remember. You were so loose back then. Didn’t you fit 5 dicks up your ass that one time?” Celestia asked. But before Luna could answer Cadence dug deeper: “5 dicks! How did you manage that? Even just finding a position for 5 stallions sounds impossible.”
“Well with a bit of planning and a lot of levitation it was not a problem at all. It also helped they weren’t all stallions... if you catch my drift.” Luna ended with a wink.
“Oooh I see. Luna you kinky mare!” Cadence snickered in response.
“We’re all kinky mares. It’s part of being a Princess don’t you think?”
“I guess that’s true. There is little we can do against what our bodies need.” Cadence paused and took a sip of tea “Now Twilight. It is your turn.”

“Oh really? I hadn’t even noticed. I was so enthralled by your tales of... sexual deviancy.” Twilight smiled nervously. Her thoughts were racing. Did Luna just admit to intercourse with different species? 
Luna smiled motherly “Twili. We told our stories to set you at ease. We can assure you, nothing you have done we haven’t tried ourselves.”
“Sigh. Alright. So I went in blind, like literally wearing a blindfold, yet I was immediately drawn towards my... partner. He was stuck in the bed somehow. Only his dick poked out.”
“Oh I know those. It’s one of Pinkie Pie’s designs. The male is totally helpless in these.”
“Yup! I usually tease ‘em a bit too so they are eager to let loose so to say.” Pinkie added while acting out a blow job for a moment.
“Er… yes. He was very eager. And I guess I was too. I have never lost control over myself like this. My whole body acted on its own. Now that I think back at it, that’s pretty scary. If something like that would have happened in public! Imagine the embarrassment! But the intercourse itself was incredible. I know of no experience that could even remotely compare to it.
The other princesses had a round of laughter. This time not to tease, but as ponies who had had the same experiences.
“Being a Princess comes with huge responsibilities. Mind blowing orgasms are a few of the perks of the job.” Celestia explained.

“Yeah!” Twilight said, surprised by her own enthusiasm and blushed harder “I guess. I mean… it was nice. So… erm… how long until I can- … have to do that again?”
This is when Pinky Pie bumped back into the conversation, by poking her head out from under the table next to the shy alicorn. “Oh you can cum by anytime you like just gimme a heads up so I can prepare someone for you. Or if its really urgent I’ll visit and eat you out myself!”
“PINKIE!”
“Don’t reject her offer so quickly dear Twilight.” Luna replied “Pinkie Pie’s tongue is incredibly long and she uses it well.”
Pinkie’s head disappears under the table and reappears between Princess Luna’s legs. “Oh Princess Luna. I had no idea you liked it so much. I’m would totally make you squeal with pleasure right now, but Twilight is angry enough with me already.”
Seeing how Twilight had turned from ‘embarrassment red’ to ‘pissed off red’ Celestia intervened. “Luna! Pinkie! ENOUGH. Twilight’s body may in full bloom already, but her mind is still budding. Give her some time. And some space.” Then addressing her student directly “My faithful student. In regards to your question. For now I recommend an intimate meeting at least once per week. This should prevent you from losing control like that again. Once you have adjusted to your new body, it will let you know how much and how often is best for you.”

The measured response had the desired effect and calmed Twilight down “Thank you Princess Celestia. All of you, thank you. I will try my best to explore this new… aspect in my life. Pinkie Pie?”
“Yes?”
“Can you arrange another meeting this weekend? Same like last time with blindfolds and such.
“Sure. Same size or bigger?”
“Uh… bigger please.”
After another round of snickering that even Twilight joined in, the Princesses departed. An exciting new chapter in Twilight’s life had begun.

ᐅ The second time… ᐊ
