The Experiment (Regular Version)
Spike sighed in boredom as he swept the floor of Twilight's castle. Even though it mostly kept itself clean, it still needed occasional upkeep. His body had grown over the past few years, becoming taller and more nimble. In fact, he looked quite similar to the adolescent form he had taken on his birthday many years ago when his greed had overtaken him.
In his mind's eye, however, he was not sweeping the castle floor. Instead he was in Rarity's bedroom, staring at the mare while she lay on her bed. Rarity lay on her side in a sexy pose, wearing a set of translucent blue silky lingerie to match. Her mane was no longer done up in its trademark curls, and was instead let down, flowing gracefully down her neck. It was straight and finely combed, as was her tail, which was flicked to the right to show off her wet, dripping pussy. She looked back at Spike with lust sparkling in her eyes.
"Well, what are you waiting for, Spike?" the imaginary Rarity asked in a quiet, sultry tone. "Come and get it." She wiggled her hips seductively, giving him a look that would have let him know exactly what she wanted, even without any words to accompany it.
"You look so hot, Rarity," he whispered aloud. Suddenly, he bumped hard face-first into a wall. He opened his eyes and rubbed his tender nose, realizing that he had closed his eyes and focused on the daydream but had not stopped sweeping. He admonished himself for not being able to focus.
"Man, what's wrong with me?" he asked no one in particular. "I can't focus with these stupid daydreams in my head." He knew what the "daydreams" were, of course. Twilight had given him the Birds and the Bees talk many years earlier, and he knew quite a bit about sex; he had even fooled around with Apple Bloom once or twice already. But that did not make the fantasies any less annoying.
Eventually, he dropped back into his chores, trying to force himself to think about anything other than Rarity. Naturally, Rainbow Dash came to mind instead. He briefly pictured her rump while she was doing her morning stretches, then shook the vision out of his head.
Seriously, Spike, she's got a coltfriend. Just imagine what Soarin' would do if he knew what you were thinking! Finally, Spike managed to keep himself from thinking about any mares by humming the Winter Wrap-Up song. That always kept him occupied.
Princess Twilight Sparkle, the lavender alicorn and the Princess of Friendship, was busy. She did not particularly want to be, nor did she even need to be, really. The most demanding job she had was making sure her enormous library was organized. But she had never liked having too much down time, and so had assigned herself several random books to read.
She finally closed the book she had just finished reading, setting it to the side on top of the pile of finished books. When she looked over at the stack of books left to read, she noticed a small, blue tome labeled "A Reference Guide to Dragons." She picked it up in her magic and opened it, figuring that it would be quite helpful in her raising of Spike.
The first few pages included a table of contents, which Twilight perused curiously. The section on behavior included several subsections detailing things like their inherent greed and regular migration, but the sections on physiology and social structure were oddly short, even for the small book that it was.
Flipping through the book's pages, Twilight realized that much of the information that was even in the book was guesswork, and all the known information was somehow related to the migration. The diagram of the anatomy was clearly modeled after a pegasus rather than based on any actual observations; the skeleton did not even look vaguely reptilian. Whoever had written this book had obviously not done all their research.
Twilight snapped the book closed in frustration, tossing it into the trash can. But then she paused. She looked to the book sitting in the small garbage can, thinking. Eventually she retrieved it, gazing thoughtfully at its cover.
"I have a dragon," she said aloud. "If there's no good information on them... then I can get it myself! I'll keep a record, send the results into Scientific Equestrian, then get a book deal, and then I'll write the most informative book on dragons ever written, and become known throughout Equestria as the one who revolutionized ponykind's understanding of—" BONK!
Twilight rubbed her head and saw that she had risen up to the ceiling in her excitement. She chuckled nervously, thankful that nopony had seen it happen.
"Heh heh. Oops."
Twilight walked into the throne room, her hooves clacking quietly on the crystal floor. She passed by her and Spike's thrones and headed toward the back of the chamber, finding a small door. Focusing her magic, she summoned a gold key which popped into existence in front of her. Inserting it into the lock, she turned it and opened the door to reveal the large closet that she had repurposed into a private office.
Upon realizing just how large the castle was, she had installed an intercom system to broadcast her voice to every part of the castle, in case she and Spike were on opposite ends of the enormous structure. She walked up to the table and pressed the button, leaning into the microphone.
"Spike, could you come to the dining hall, please? I'd like to talk to you about something." With that, she exited the office and took flight, flying through the open throne room door and toward the dining hall.
She flew lazily into the dining hall, landing with a quiet clop on the floor. She took a seat at the large table and waited for Spike to arrive, which he did a few minutes later.
"You wanted to see me, Twilight?" he said, closing the large door as gently as he could.
"Yes, Spike," she replied. "I was just reading in the library and I saw a book on dragons, so I decided to read it." Spike grinned.
"Oh, that's cool! What'd you learn from it?"
"Absolutely nothing," replied Twilight. Spike's expression turned to confusion.
"Huh?"
"The thing was full of inaccurate information and guesswork. The pony who wrote it obviously didn't know what they were talking about. I got a bit frustrated with it. But then something occurred to me."
"What was that?" asked Spike, sitting down at the table in the seat next to Twilight. His now longer legs had a bit of difficulty fitting under the table, so he turned the chair to face Twilight.
"I've been raising you since you were a hatchling. If anypony knows about dragons, it's me!" She put a hoof to her chest, pointing at herself. "I could conduct a study of dragon physiology. And with you going through puberty, now would be the perfect time! Your body is changing, preparing you for adulthood. We understand how it works in ponies, but dragons are a whole different matter! Just think of all we could learn!"
Spike noticed a gleam in Twilight's eyes that set off warning bells in his head. But those warning bells were drowned out by an image of Twilight laying face-down on a bed with her rump in the air. She held a clipboard and quill in her magic, ready to document the imminent mating experience.
Spike shook his head to clear the image and return to reality. He looked at Twilight, who was still looking excitedly to him, waiting for his answer.
"Uh.. yeah, sure," he finally said. Twilight let out a quite un-princess-like squeal of excitement.
"Eee! Excellent! Let's get started right away!"
"Whoa!" he exclaimed as his hand was grabbed in Twilight's magical grip and he was dragged across the floor towards her lab.
The laboratory in Twilight's castle was similar to the one from the Golden Oak library before it was destroyed. Except, of course, that it was much larger and above ground. Spike and Twilight entered the lab and moved toward a long table in a corner. Twilight stopped in front of it and gestured to it.
"If you would, Spike." Spike nodded and hopped up onto the table, sitting upright with his legs hanging over the edge. Twilight donned a white lab coat and grabbed a stethoscope. She put in the earpieces and raised the end to Spike's chest, moving it occasionally and listening to his heartbeat and breathing.
After about a minute of this, she dropped the stethoscope and grabbed a notepad and quill, scribbling something down. She then brought over a small rubber mallet and rapped it against Spike's knee, and his leg twitched in response. Then she scribbled down something else. She put away the mallet and stethoscope and placed her hoof on his shoulder.
"I need you to lay down on the table," she said. "I'm going to perform a scanning spell to analyze your skeletal structure."
"Alright." Spike turned and brought his legs up onto the table, lying down and resting his head on the cylindrical pillow at one end. When he flattened out his back, his feet almost reached the end of the table, showing that he was a bit taller than the average pony would be if they stood upright.
Once Spike was situated, Twilight lit her horn. She focused for a moment, gathering magical power, then produced a beam that scanned over his form. It felt tingly as her magic washed over him, and after a few moments, he thought it was starting to feel... pleasant.
Eventually, Twilight finished the spell. When she opened her eyes, she gasped and blushed. In between Spike's legs, his genital slit had opened, revealing a pair of pinkish hemipenes.
They were vertically situated, one above the other, with the top one being slightly larger than the bottom. Their pinkish surface, contrasting with Spike's light green underbelly scales, was crossed with a few veins. There was no medial ring like a stallion had, but there was a line of small nubs running up the underside of each, and they both curved upward into tapering points. Twilight guessed that the top one was maybe eight inches long, the bottom about an inch shorter. There were no testicles to be seen; Twilight reasoned that they must be internal like most other reptiles.
Spike opened his eyes at Twilight's gasp. He looked down and saw that his dicks had shown themselves. He blushed a bit, but found Twilight's stare oddly exciting.
"Um..." said Twilight, not knowing what else to say, "they certainly look... developed." Spike did not reply. He could not stop looking at Twilight's eyes. He could see that her eyes were glued to both his cocks, and he found that... exhilarating. He felt them throb with his heartbeat, bouncing slightly, and Twilight's eyes amusingly followed their slight motion.
Spike found his hand wandering instinctively to his groin, and his dicks throbbed again. He loved the feeling of Twilight's eyes on him, and he wanted to do more than just sit there. Suddenly, Twilight shook her head and looked away.
"It-It's just a penis," she said. "Nothing I haven't seen before. No, it's two penises," she murmured. She shook her head again. "It doesn't matter! I'll just have to..." She turned back to Spike, her eyes immediately locking onto the masses between his legs. "...ignore them."
"You know," said Spike, sliding his right hand down next to them, "you can look at them. I don't mind."
"Well," said Twilight after a pause, "I'd eventually have to study them anyway. I guess I might as well do it now." She grabbed a tape measure from the other side of the room and unrolled it. She was about to hold it up to measure him, but then she paused.
"May I?" she asked, looking up at Spike
"Be my guest," he replied with a smile. A bit too quickly, Twilight held the measure up to the first one on the top. She was apparently wrong in her original estimate. Her mouth watered when she read the actual measurement: 8.75 inches.
She promptly chided herself for even considering it. She had raised him from an egg; he was like her little brother! And yet there she was, gazing hungrily at his twin shafts, imagining them plunging inside of her—
No! She refused to allow her mind to go in that direction. She decided that she would view them in only the most scientific of terms. Then there was no way for them to get to her. Yes, scientific terms only.
Spike trembled as Twilight measured his twin penises. She was leaning incredibly close and he could just barely feel her breath on the tips. His fingers slowly massaged the base of the bottom shaft as he struggled to keep his urges under control.
Twilight was about to measure the bottom shaft, but she realized Spike's fingers were in the way. She quietly cleared her throat and his hand flinched away. She then measured the appendage at approximately 7.875 inches; slightly shorter than the top, but no less impressive.
She then measured the circumference of both shafts. First the bottom, which measured about 5.5 inches around. After doing some quick mental math, it came out to an impressive 1.75 inches thick. Then came the top one. It measured 6.25 inches around, which made it more than 2 inches thick! He was large in both places; even the bottom shaft was thicker than that of a full-grown stallion.
Her mouth was truly watering now as she smelled the scent of his groin, a musky aroma smelling of maturity and masculinity. Her tongue extended on its own, trying to touch the skin. She wanted to taste it. She convinced herself that it would not be a terrible thing; she did want to know everything about dragons after all. She leaned in, ever so slowly, and gingerly touched her tongue to the flesh of the shaft.
The skin felt almost blisteringly hot compared to the cold air of the lab, fueled by the natural heat from Spike's core. She could taste the salty flesh, punctuated by the heavy taste of his musk. Finally abandoning pretense, Twilight gave Spike's bottom cock a long, full-bodied lick. She found that the nubs were soft and flexible, like they were made of rubber. As she ran her tongue over the skin, she moaned at the delicious taste.
Spike moaned as well, propping himself up on his elbows. Twilight licked up and down his lower shaft, sending shivers of pleasure through his adolescent body. He shook with the feeling of Twilight licking his cock, something that he had never felt before.
Twilight leaned in a bit farther and brought her lips to the shaft, kissing it. As her lips mashed against the skin, Spike leaked out a small drop of precum, some of which smeared on the fur of Twilight's muzzle as she worked. Spike groaned in pleasure as she raised a hoof to rest on his thigh, kissing the shaft of his dick more deeply. She was gradually working her way up toward the tip, licking and kissing all the way.
Eventually, Twilight worked her way up to the tip. She licked until the tip of her tongue was just touching the tip, then moved her lips close. She took a breath of anticipation, then quietly moaned as she wrapped her lips around it.
Spike threw back his head and groaned in ecstasy as Twilight slowly took in his hard bottom shaft. She gradually inhaled his cock, and Spike could feel her throat spreading to accommodate his girth. The soft flesh parted and his lower cock slowly sank down her gullet, while the underside of his upper shaft rubbed pleasurably against her muzzle. He placed a hand on her head, fingering her soft mane.
"That feels really good, Twi," he said. Twilight opened her eyes and looked up at him, then promptly lifted her mouth off his member.
"No!" she said, shaking her head. "I shouldn't have done that!" She sat down on a reclining seat near the table. Spike hopped off the table and knelt down next to her so that their eyes were level, placing a comforting hand on her shoulder and calming her somewhat.
"It's okay, Twi," he said. "I want it, and I know you want it. So what's the problem?" She looked at the floor.
"I feel like I'm taking advantage of you," she said.
"Now you know that's not true." He leaned forward, closing the distance between them. He placed his right hand on the back of her neck, holding her head in his claws. He leaned in closer to her and brought her face closer in turn, until they could feel each other's breath on their faces. She looked up at him, gazing into his reptilian, slit-pupil eyes. He leaned in just a bit closer, their eyes drifted closed, and their lips finally connected.
Twilight inhaled sharply and tensed, then seemed to melt in Spike's embrace. He sucked gently on her bottom lip, then moved to the top lip and did the same. Their mouths moved in unison, keeping in perfect harmony. After a few seconds, Spike broke the kiss, pulling away and leaving Twilight wanting more. He opened his eyes and looked at her.
"You know, I never told you, but... I've wanted this for a long time," he told her. Twilight put a hoof on Spike's neck.
"Me too," she said. Then she pulled him into another, more passionate kiss.
Their lips mashed together frantically as Spike released his pent-up passion. Twilight went along, doing her best to keep up with the horny dragon. As the kiss grew more passionate, Twilight felt Spike's long, snake-like tongue pressing against her teeth. She eventually opened her mouth, allowing it access.
Spike snaked his long tongue into Twilight's mouth, licking the insides of her cheeks. Twilight's tongue responded as best it could, trying to wrap around Spike's, but his tongue was much more flexible and ended up wrapping around Twilight's instead.
She moaned into his mouth as they kissed, and she grabbed his sides, wrapping her hind legs around him. His members, both now rock-hard, were brought much closer to her body, and she could feel the texture of their nubs rubbing against the skin between her teats, which were now becoming slightly swollen with her arousal. As she leaned back, she could also feel that her wings had splayed out of their own volition, signifying her arousal in a familiar imitation of a penile erection.
Spike finally broke the kiss and smiled at Twilight with half-lidded eyes.
"You know," he said, "you did something for me. Now it's only fair that I return the favor." Twilight briefly wondered what he meant before he knelt down between her hind legs.
He placed one hand on Twilight's left thigh, sending a shiver through her body as she felt him getting closer to her nether regions. His other hand trailed up her right hind leg, teasingly brushing the fur of her coat as it slid closer to its goal.
Spike leaned his face in close until Twilight could feel his hot breath on her swollen sex. Finally, his claw reached her labia, moving around them just far enough away to keep from satisfying her. It trailed up one side, moving around her clitoris in a clockwise direction. It then moved down and around, passing over her perineum and wrapping counterclockwise around the circumference of her anus. And all the while Twilight continued to feel his steamy breath washing over her pussy.
Spike gazed at the wet organ in front of him and his mouth watered as he imagined shoving his face directly into it. But he had to make sure not to go too fast; Twilight had to enjoy it too. So instead, he stuck out his tongue, the thin appendage gliding ever so slowly toward her dripping slit. It eventually reached the topmost portion of her vulva, and the forked end flicked lightly over her clitoris, causing her pussy to wink and her whole body to shudder.
Smiling at her response, Spike moved his tongue lower, continuing to move his claw around her nethers. The end of his tongue moved down around her labia and up into her slit, then with a slight push, slowly slipped inside her.
Spike could taste Twilight's arousal, his tongue being quickly coated in a thick layer of vaginal juices. As he squeezed his tongue deeper inside her, Twilight gave a throaty moan, and he could feel the vibrations of her voice through her walls. He was nearly overwhelmed by the succulent taste of her juices, sweet and tangy like nectar. Her vaginal muscles flexed, trying to draw him in deeper, but he maintained careful control, wiggling his tongue as it gradually slipped deeper inside her, drawing out more pleasured moans from the alicorn.
Soon, he hit an apparent wall at the end of the tunnel, which he knew to be her cervix. He curled his tongue, flipping it back on itself, and pressed deeper, pushing the tip of his tongue back toward the entrance. She began to wink more frequently, and Spike could feel and taste a fresh flood of sweet juices as her arousal intensified.
Finally, the end of his tongue poked back out of her vagina, nestled on top of itself. It then curled upward, and the forked end reached Twilight's clitoris, which had now become incredibly sensitive.
Spike then pressed his lips to her labia and began to gently suck on the puffy pussy lips. He wiggled his tongue and Twilight squealed in bliss as she was pleasured from both the inside and the outside. The end of Spike's tongue flicked rapidly against her clitoris, and at the same time, the main body of his tongue wiggled against her inner walls, feeling like a warm, living vibrator. All the while, his lips worked the outside, massaging the sensitive mounds of flesh.
"Oh, Spike!" she shouted. "Don't stop!" Spike reached his right hand down to attend to his erections. He wrapped it around the top one, stroking it slowly as he drank Twilight's nectar, while still continuing his ministrations with his tongue. At the same time, he brought his left hand up and placed a claw on her labia, then pushed it inside her underneath his tongue.
Twilight felt Spike's tongue moving like a vibrator and his lips massaging her labia, giving her untold amounts of pleasure. Then she felt his finger entering the fray as well, and everything intensified. He rested the heel of his hand at the base of her tail to keep it steady, then slowly worked a finger into her passage. She squirmed as he began thrusting it in and out of her pussy, first slowly, then with gradually increasing speed. She could feel the pressure building, and she knew that she was fast approaching her orgasm.
"Yes, Spike!" she yelled. "I'm so close! Go faster!" She was winking furiously now, her clit poking in and out from between her labia at lightning speed. Spike grew more fervent, stroking his shaft faster.
He pressed his lips tightly to her pussy, waiting for an opportunity to make his planned move. Her clit winked again, and this time, Spike wrapped his lips tightly around it, sucking on it in an attempt to drive her over the edge.
The maneuver worked, and Twilight screamed in ecstasy as she came, squirting a flood of juices onto Spike's face and hand, who opened his mouth wider in an attempt to catch all of the fluids. He loudly slurped the sweet marecum from Twilight's pussy, drinking down the thin fluid of her climax. It tasted like the sweetest apple cider, and he groaned with satisfaction as it slid down his throat, satisfying him like water from a desert oasis.
When he had drank his fill and sucked Twilight dry, he drew away, slipping his long tongue out of her slit with a small schlick. A thin strand of saliva briefly connected his bottom lip to her pussy before breaking silently. His left hand was covered in the fluid of her climax, and the translucent liquid dripped down his wrist. He brought his hand to his mouth, then one by one, greedily sucked the rest of her cum off his fingers.
Twilight had laid back after her mind-blowing orgasm, basking in the afterglow, but now she sat up on her elbows, looking at Spike with hunger still in her eyes. He noticed her gaze and chuckled.
"You still want to go?" he asked, licking his lips.
"Yeah," she said. Spike grinned deviously and wrapped his strong arms around her. He placed one hand on her flank and the other on her back, and she yelped in surprise as she was lifted into the air. She gripped his shoulders to keep from falling, pressing herself against his muscular chest. He carried her over to the table that he had been sitting on previously, then laid her down gently on her back, taking care not to disturb her delicate feathers.
He stood over her, looking into her eyes as she looked back into his. Then he closed his eyes and kissed her passionately once again. Twilight could still taste the last remnants of her climax on his lips, and it was not an altogether unpleasant taste. In fact, it was actually rather sweet, and though Twilight would probably be loath to admit it, she found she rather enjoyed it.
His left hand grasped her cutie mark while his other hand moved up and down, exploring her body. He reached a pair of small mounds just above her pussy—her teats—and brought his left hand up to join his right. He grasped both mounds of tender, spongy flesh, brushing his thumbs lightly over the erect nipples. Twilight gave a light, delicate moan into his mouth at the soft touch, and her hind legs twitched before wrapping more tightly around him.
As Twilight pulled his body closer, she could feel Spike's woefully neglected dicks rubbing against her, smearing precum on her lavender fur. Her own genitals were also once again dripping with need, smearing her own juices on Spike in turn as they ground their hips together.
Spike stopped moving and pulled his mouth away from Twilight's, suddenly looking at her with a serious expression.
"I'm gonna put it in, okay?" he said. "Let me know if it hurts or anything."
"Okay," she replied. "I'm ready." Spike nodded and pulled back a bit to get ready. He used his hand to guide his bottom shaft forward and touched Twilight's labia, causing her to tense in anticipation. He then pressed forward, the lower shaft spreading her soft pussy lips and entering her silky depths.
Twilight's lubricated walls welcomed Spike's lower cock, the hard member sliding smoothly into her like a hot knife through butter. The soft nubs on the underside rubbed against the back wall of her tunnel, sending a luscious burning sensation throughout her lower body and down her legs. Her tail flicked between Spike's legs, wrapping loosely around his own.
His upper member rubbed against her belly between her teats so that he was essentially teat-fucking her at the same time, while the nubs produced a wonderful feeling of friction against her partially covered clit. Every time she winked, the friction grew suddenly more intense as the nubs came into contact with it, which naturally increased her desire, causing her to wink more.
As she winked her clit, it massaged Spike's shaft, and the adolescent dragon let out a short groan. Twilight's body was responding to him by reciprocating the pleasure he gave tenfold, and it was almost too much for him to handle.
He finally felt Twilight's fur brush against his groin and realized he had bottomed out inside her. He could have sworn that he had been going longer than that, but that was of no consequence. He stood still for a moment, resting inside her, then slowly pulled out until the tip of his lower shaft was just inside her.
He grabbed her cutie mark with one hand and the back of her neck with the other, looking into her eyes as he began thrusting in and out of her. Slowly at first, then faster and faster, Spike thrust his lower cock in and out of Twilight's cunt, driving home each powerful thrust with a grunt of pleasure, which were all echoed by Twilight. She grunted in pleasure, holding Spike's shoulders as he fucked her.
"Oh, Spike, it feels so good."
Spike leaned over a bit further, trying to get a better angle of penetration, and he grabbed Twilight's hips and lifted them slightly. This brought her hind legs up to point almost straight into the air, while also causing her to curl up into a quite vulnerable position. It also had the side effect of hitting a particularly sensitive spot within her. Twilight's pussy clenched and her moans intensified and grew in pitch, which Spike took as positive feedback.
"You like that, Twi?" he asked as he continued to fuck her.
"Oh, yes, Spike!" she moaned in response. "It feels amazing!" Spike's hips sped up more and he put more power into them until they slapped against Twilight's thighs with every powerful thrust.
Twilight could feel the pressure as she approached her second orgasm. Her hind legs squeezed around his waist and she gyrated her hips, trying to encourage him with her body as well as her words.
"I'm close again, Spike!" she whined in his ear. "Rut me harder!" He placed his hands on her shoulders and continued with his powerful thrusting, grunting with the effort of every movement, and Twilight's tunnel clenched once again.
"Oh, Celestiaaa!" she screamed. Her wings flapped wildly in the throes of bliss and she squirted out another gush of pussy juice onto Spike's double members, though it mostly coated the one on the bottom. Though she did not produce as much fluid as the first time, her orgasm was no less intense.
Once the euphoric high had reduced somewhat, she shivered and gasped for air, still holding onto him tightly with all four limbs. He had stopped thrusting when she came, and now slowly pulled out of her, sliding out with a small schlurp. He looked at her expectantly, waiting for her to voice her wishes.
Once she had regained control over her facial muscles, Twilight smiled at him, using her magic to brush a few sweaty strands of hair away from her eyes.
"I feel guilty now for not giving you any satisfaction," she said breathlessly, propping herself up on her elbows.
"It's alright," he said with a smile. "I'm just glad you finally know how I feel about you. Although there is one thing I wanted to try. And you can say no if you want; I promise I won't get mad or anything."
"What is it?" she asked, prepared for the worst.
It was something that he had tried to persuade Apple Bloom to try once, but she had refused, saying that she "don't want nothin' up there." He hoped that Twilight would not do the same, but there was only one way to know, and that was to ask.
"Can I double-penetrate you?"
Of the many things Twilight had been dreading that he would ask, that was oddly not one of them. It made sense, she supposed. Since dragons had hemipenes and mares had two rear orifices, it was only the logical conclusion, but somehow it had not entered her mind until that moment.
She felt a bizarre mixture of emotions at the request, among them excitement, arousal, and anticipation, coupled with uncertainty, fear, and trepidation. Though her mind had mostly been made up on the subject of anal, double penetration had never been at the forefront of her thoughts, considering that she had never been interested in being with multiple stallions at a time. But now that she was being presented with the possibility of having the experience with a single individual, it was rapidly growing to be awfully enticing.
"I don't see why not," she said eventually. "I've tried anal before, but never that. Sounds like it could be fun." Spike grinned, showing his teeth and licking his lips.
"Awesome," he said.
He moved back up to Twilight, who was still on her back, bringing his two dicks once again to her warm nethers. He rubbed his lower shaft along her slit, slathering it with more of her juices, then moved his hips downward, bringing the top member to her pussy. Spike moved ever so carefully, moving his cocks in expert synchronicity so that they teased at both of her holes.
His top shaft spread her soft, pliable labia, which parted to allow the hot organ entrance. He pushed forward slower and more carefully than seemingly any stallion ever could, sliding the thin tip inside her, and he placed a steadying hand on her right hind leg as she gasped in pleasure.
Meanwhile, the bottom member poked against her puckered anus, smearing her leftover juices across the wrinkled skin. The tip prodded at the entrance, begging to be let in, and she remembered her previous experiences and relaxed her muscles. Lubricated by her slippery juices, it slid inside and entered her rectum.
Twilight groaned as the thick rod penetrated her ass, spreading her cheeks and giving her a full feeling. As the draconic cock sank deeper, the full feeling increased in intensity, and she gave a breathy moan of pleasure as she felt the texture of the soft nubs sequentially popping inside her. As it moved, its girth also gradually increased, and Twilight could feel her rump spreading more and more to accommodate it.
At the same time, her pussy was stretched even more than before, Spike's top dick being longer and thicker than the one on the bottom. She moaned loudly in a mixture of pain and pleasure as her elastic walls stretched to allow him entrance, expanding until they were stretched taut around his thick, hard cock.
Her ass was suffering a similar fate. Having hardly ever been worked at all, she could feel her anus straining against the thick rod, but she knew that Spike would do his best not to hurt her, so she was confident that she would be alright.
Spike groaned and grunted as he bottomed out inside both of Twilight's holes, fighting not to cum right then and there at the tightness. He froze for a moment, allowing his loins to cool off, before starting his thrusting.
He started pumping in and out, steadying Twilight's barrel with one hand while holding her right leg in the air with the other. He groaned and lightly squeezed her leg.
"Agh, fuck, Twi," he said, "your holes are both so tight."
Spike thrust faster, and Twilight screamed in bliss as she felt Spike's cocks fucking both her pussy and her ass, only separated by what seemed to be a paper-thin wall of flesh. Her anal walls were struggling to put up with the punishment being inflicted upon them by Spike's pounding, but the lubrication from Twilight's last orgasm had not yet been exhausted, and in fact was even being bolstered by the copious juices dripping down from her stretched snatch. Her burning desire radiated through her legs and despite all that she had gone through already, she felt yet another climax looming on the horizon.
Spike, meanwhile, was feeling pressure in his own loins and knew that his orgasm was imminent. His thrusts began to speed up and become more erratic and soon his thighs were once again slapping against Twilight's, the lewd sounds occasionally punctuated by their moans.
"Oh, gosh, Twi," he gasped. "I'm getting really close!"
"Unh, me too!" shouted Twilight. "Do it inside, Spike! Cum inside me!"
Spike's thrusts became slower and more powerful, smacking Twilight's rump with his full strength, and then he finally gave one last forceful shove, simultaneously shooting two thick loads of cum into her ass and pussy.
Like a broken dam, Spike's hot dragon seed shot deep into Twilight's belly. The cum came in spurts, the first of which was like a flood in and of itself, followed by progressively smaller shots that each still seemed larger than a full-grown stallion's entire payload. The cock stuffed in her cunt seemed to shoot gallons of burning jizz inside of her, and soon her pussy felt like a water balloon fit to burst from the sheer volume of spunk being shot inside it.
Her ass, meanwhile, felt like she had had a barrel of hot cider pumped into it, and the steaming hot, viscous fluid still continued to fill her hole, leaving the insides of her colon soaked and dripping with thick liquid pleasure. The syrupy sperm oozed out of both her holes around Spike's twin cocks, and it was at that point that she could take no more.
Twilight convulsed on the table, her back arching as she experienced one of the most intense orgasms of her life. Every muscle in her body contracted as she rode wave after wave of utter bliss, like a surfer on a celestial ocean. She heard a noise in the distance and realized that she was screaming Spike's name at the top of her lungs.
She finally drifted down from her mind-shattering climax and she gasped for breath, her voice quieting. She breathed heavily for a moment, simply basking in Spike's presence and enjoying the feeling of both his cocks nestled inside her. Then he spoke, and she was broken out of her reverie.
"Holy guacamole," he said breathlessly, shooting her a sultry smile. "You sure know how to have fun." He slowly pulled away from her, and both of his now diminishing erections slipped out of her, dripping snow-white fluid. A thick line of cream flowed slowly out of her pussy and down her perineum. After a couple of inches it joined with the stream coming from her abused asshole, which was slightly agape, and formed a tiny but growing white puddle beside the base of her tail.
He hopped up onto the table and positioned himself behind her, taking her in his arms. She snuggled up against him, relaxing in his embrace, and he gave her a sensual kiss on her neck before lying back against the wall behind him.
After three orgasms in a row, Twilight felt completely drained of all energy and fluids, and she knew he probably felt similarly. So she laid there, basking in his presence, until at length, she fell into a peaceful sleep.
The Experiment (Kinkier Version)
Spike sighed in boredom as he swept the floor of Twilight's castle. Even though it mostly kept itself clean, it still needed occasional upkeep. His body had grown over the past few years, becoming taller and more nimble. In fact, he looked quite similar to the adolescent form he had taken on his birthday many years ago when his greed had overtaken him.
In his mind's eye, however, he was not sweeping the castle floor. Instead he was in Rarity's bedroom, staring at the mare while she lay on her bed. Rarity lay on her side in a sexy pose, wearing a set of translucent blue silky lingerie to match. Her mane was no longer done up in its trademark curls, and was instead let down, flowing gracefully down her neck. It was straight and finely combed, as was her tail, which was flicked to the right to show off her wet, dripping pussy. She looked back at Spike with lust sparkling in her eyes.
"Well, what are you waiting for, Spike?" the imaginary Rarity asked in a quiet, sultry tone. "Come and get it." She wiggled her hips seductively, giving him a look that would have let him know exactly what she wanted, even without any words to accompany it.
"You look so hot, Rarity," he whispered aloud. Suddenly, he bumped hard face-first into a wall. He opened his eyes and rubbed his tender nose, realizing that he had closed his eyes and focused on the daydream but had not stopped sweeping. He admonished himself for not being able to focus.
"Man, what's wrong with me?" he asked no one in particular. "I can't focus with these stupid daydreams in my head." He knew what the "daydreams" were, of course. Twilight had given him the Birds and the Bees talk many years earlier, and he knew quite a bit about sex; he had even fooled around with Apple Bloom once or twice already. But that did not make the fantasies any less annoying.
Eventually, he dropped back into his chores, trying to force himself to think about anything other than Rarity. Naturally, Rainbow Dash came to mind instead. He briefly pictured her rump while she was doing her morning stretches, then shook the vision out of his head.
Seriously, Spike, she's got a coltfriend. Just imagine what Soarin' would do if he knew what you were thinking! Finally, Spike managed to keep himself from thinking about any mares by humming the Winter Wrap-Up song. That always kept him occupied.
Princess Twilight Sparkle, the lavender alicorn and the Princess of Friendship, was busy. She did not particularly want to be, nor did she even need to be, really. The most demanding job she had was making sure her enormous library was organized. But she had never liked having too much down time, and so had assigned herself several random books to read.
She finally closed the book she had just finished reading, setting it to the side on top of the pile of finished books. When she looked over at the stack of books left to read, she noticed a small, blue tome labeled "A Reference Guide to Dragons." She picked it up in her magic and opened it, figuring that it would be quite helpful in her raising of Spike.
The first few pages included a table of contents, which Twilight perused curiously. The section on behavior included several subsections detailing things like their inherent greed and regular migration, but the sections on physiology and social structure were oddly short, even for the small book that it was.
Flipping through the book's pages, Twilight realized that much of the information that was even in the book was guesswork, and all the known information was somehow related to the migration. The diagram of the anatomy was clearly modeled after a pegasus rather than based on any actual observations; the skeleton did not even look vaguely reptilian. Whoever had written this book had obviously not done all their research.
Twilight snapped the book closed in frustration, tossing it into the trash can. But then she paused. She looked to the book sitting in the small garbage can, thinking. Eventually she retrieved it, gazing thoughtfully at its cover.
"I have a dragon," she said aloud. "If there's no good information on them... then I can get it myself! I'll keep a record, send the results into Scientific Equestrian, then get a book deal, and then I'll write the most informative book on dragons ever written, and become known throughout Equestria as the one who revolutionized ponykind's understanding of—" BONK!
Twilight rubbed her head and saw that she had risen up to the ceiling in her excitement. She chuckled nervously, thankful that nopony had seen it happen.
"Heh heh. Oops."
Twilight walked into the throne room, her hooves clacking quietly on the crystal floor. She passed by her and Spike's thrones and headed toward the back of the chamber, finding a small door. Focusing her magic, she summoned a gold key which popped into existence in front of her. Inserting it into the lock, she turned it and opened the door to reveal the large closet that she had repurposed into a private office.
Upon realizing just how large the castle was, she had installed an intercom system to broadcast her voice to every part of the castle, in case she and Spike were on opposite ends of the enormous structure. She walked up to the table and pressed the button, leaning into the microphone.
"Spike, could you come to the dining hall, please? I'd like to talk to you about something." With that, she exited the office and took flight, flying through the open throne room door and toward the dining hall.
She flew lazily into the dining hall, landing with a quiet clop on the floor. She took a seat at the large table and waited for Spike to arrive, which he did a few minutes later.
"You wanted to see me, Twilight?" he said, closing the large door as gently as he could.
"Yes, Spike," she replied. "I was just reading in the library and I saw a book on dragons, so I decided to read it." Spike grinned.
"Oh, that's cool! What'd you learn from it?"
"Absolutely nothing," replied Twilight. Spike's expression turned to confusion.
"Huh?"
"The thing was full of inaccurate information and guesswork. The pony who wrote it obviously didn't know what they were talking about. I got a bit frustrated with it. But then something occurred to me."
"What was that?" asked Spike, sitting down at the table in the seat next to Twilight. His now longer legs had a bit of difficulty fitting under the table, so he turned the chair to face Twilight.
"I've been raising you since you were a hatchling. If anypony knows about dragons, it's me!" She put a hoof to her chest, pointing at herself. "I could conduct a study of dragon physiology. And with you going through puberty, now would be the perfect time! Your body is changing, preparing you for adulthood. We understand how it works in ponies, but dragons are a whole different matter! Just think of all we could learn!"
Spike noticed a gleam in Twilight's eyes that set off warning bells in his head. But those warning bells were drowned out by an image of Twilight laying face-down on a bed with her rump in the air. She held a clipboard and quill in her magic, ready to document the imminent mating experience.
Spike shook his head to clear the image and return to reality. He looked at Twilight, who was still looking excitedly to him, waiting for his answer.
"Uh.. yeah, sure," he finally said. Twilight let out a quite un-princess-like squeal of excitement.
"Eee! Excellent! Let's get started right away!"
"Whoa!" he exclaimed as his hand was grabbed in Twilight's magical grip and he was dragged across the floor towards her lab.
The laboratory in Twilight's castle was similar to the one from the Golden Oak library before it was destroyed. Except, of course, that it was much larger and above ground. Spike and Twilight entered the lab and moved toward a long table in a corner. Twilight stopped in front of it and gestured to it.
"If you would, Spike." Spike nodded and hopped up onto the table, sitting upright with his legs hanging over the edge. Twilight donned a white lab coat and grabbed a stethoscope. She put in the earpieces and raised the end to Spike's chest, moving it occasionally and listening to his heartbeat and breathing.
After about a minute of this, she dropped the stethoscope and grabbed a notepad and quill, scribbling something down. She then brought over a small rubber mallet and rapped it against Spike's knee, and his leg twitched in response. Then she scribbled down something else. She put away the mallet and stethoscope and placed her hoof on his shoulder.
"I need you to lay down on the table," she said. "I'm going to perform a scanning spell to analyze your skeletal structure."
"Alright." Spike turned and brought his legs up onto the table, lying down and resting his head on the cylindrical pillow at one end. When he flattened out his back, his feet almost reached the end of the table, showing that he was a bit taller than the average pony would be if they stood upright.
Once Spike was situated, Twilight lit her horn. She focused for a moment, gathering magical power, then produced a beam that scanned over his form. It felt tingly as her magic washed over him, and after a few moments, he thought it was starting to feel... pleasant.
Eventually, Twilight finished the spell. When she opened her eyes, she gasped and blushed. In between Spike's legs, his genital slit had opened, revealing a pair of pinkish hemipenes.
They were vertically situated, one above the other, with the top one being slightly larger than the bottom. Their pinkish surface, contrasting with Spike's light green underbelly scales, was crossed with a few veins. There was no medial ring like a stallion had, but there was a line of small nubs running up the underside of each, and they both curved upward into tapering points. Twilight guessed that the top one was maybe eight inches long, the bottom about an inch shorter. There were no testicles to be seen; Twilight reasoned that they must be internal like most other reptiles.
Spike opened his eyes at Twilight's gasp. He looked down and saw that his dicks had shown themselves. He blushed a bit, but found Twilight's stare oddly exciting.
"Um..." said Twilight, not knowing what else to say, "they certainly look... developed." Spike did not reply. He could not stop looking at Twilight's eyes. He could see that her eyes were glued to both his cocks, and he found that... exhilarating. He felt them throb with his heartbeat, bouncing slightly, and Twilight's eyes amusingly followed their slight motion.
Spike found his hand wandering instinctively to his groin, and his dicks throbbed again. He loved the feeling of Twilight's eyes on him, and he wanted to do more than just sit there. Suddenly, Twilight shook her head and looked away.
"It-It's just a penis," she said. "Nothing I haven't seen before. No, it's two penises," she murmured. She shook her head again. "It doesn't matter! I'll just have to..." She turned back to Spike, her eyes immediately locking onto the masses between his legs. "...ignore them."
"You know," said Spike, sliding his right hand down next to them, "you can look at them. I don't mind."
"Well," said Twilight after a pause, "I'd eventually have to study them anyway. I guess I might as well do it now." She grabbed a tape measure from the other side of the room and unrolled it. She was about to hold it up to measure him, but then she paused.
"May I?" she asked, looking up at Spike
"Be my guest," he replied with a smile. A bit too quickly, Twilight held the measure up to the first one on the top. She was apparently wrong in her original estimate. Her mouth watered when she read the actual measurement: 8.75 inches.
She promptly chided herself for even considering it. She had raised him from an egg; he was like her little brother! And yet there she was, gazing hungrily at his twin shafts, imagining them plunging inside of her—
No! She refused to allow her mind to go in that direction. She decided that she would view them in only the most scientific of terms. Then there was no way for them to get to her. Yes, scientific terms only.
Spike trembled as Twilight measured his twin penises. She was leaning incredibly close and he could just barely feel her breath on the tips. His fingers slowly massaged the base of the bottom shaft as he struggled to keep his urges under control.
Twilight was about to measure the bottom shaft, but she realized Spike's fingers were in the way. She quietly cleared her throat and his hand flinched away. She then measured the appendage at approximately 7.875 inches; slightly shorter than the top, but no less impressive.
She then measured the circumference of both shafts. First the bottom, which measured about 5.5 inches around. After doing some quick mental math, it came out to an impressive 1.75 inches thick. Then came the top one. It measured 6.25 inches around, which made it more than 2 inches thick! He was large in both places; even the bottom shaft was thicker than that of a full-grown stallion.
Her mouth was truly watering now as she smelled the scent of his groin, a musky aroma smelling of maturity and masculinity. Her tongue extended on its own, trying to touch the skin. She wanted to taste it. She convinced herself that it would not be a terrible thing; she did want to know everything about dragons after all. She leaned in, ever so slowly, and gingerly touched her tongue to the flesh of the shaft.
The skin felt almost blisteringly hot compared to the cold air of the lab, fueled by the natural heat from Spike's core. She could taste the salty flesh, punctuated by the heavy taste of his musk. Finally abandoning pretense, Twilight gave Spike's bottom cock a long, full-bodied lick. She found that the nubs were soft and flexible, like they were made of rubber. As she ran her tongue over the skin, she moaned at the delicious taste.
Spike moaned as well, propping himself up on his elbows. Twilight licked up and down his lower shaft, sending shivers of pleasure through his adolescent body. He shook with the feeling of Twilight licking his cock, something that he had never felt before.
Twilight leaned in a bit farther and brought her lips to the shaft, kissing it. As her lips mashed against the skin, Spike leaked out a small drop of precum, some of which smeared on the fur of Twilight's muzzle as she worked. Spike groaned in pleasure as she raised a hoof to rest on his thigh, kissing the shaft of his dick more deeply. She was gradually working her way up toward the tip, licking and kissing all the way.
Eventually, Twilight worked her way up to the tip. She licked until the tip of her tongue was just touching the tip, then moved her lips close. She took a breath of anticipation, then quietly moaned as she wrapped her lips around it.
Spike threw back his head and groaned in ecstasy as Twilight slowly took in his hard bottom shaft. She gradually inhaled his cock, and Spike could feel her throat spreading to accommodate his girth. The soft flesh parted and his lower cock slowly sank down her gullet, while the underside of his upper shaft rubbed pleasurably against her muzzle. He placed a hand on her head, fingering her soft mane.
"That feels really good, Twi," he said. Twilight opened her eyes and looked up at him, then promptly lifted her mouth off his member.
"No!" she said, shaking her head. "I shouldn't have done that!" She sat down on a reclining seat near the table. Spike hopped off the table and knelt down next to her so that their eyes were level, placing a comforting hand on her shoulder and calming her somewhat.
"It's okay, Twi," he said. "I want it, and I know you want it. So what's the problem?" She looked at the floor.
"I feel like I'm taking advantage of you," she said.
"Now you know that's not true." He leaned forward, closing the distance between them. He placed his right hand on the back of her neck, holding her head in his claws. He leaned in closer to her and brought her face closer in turn, until they could feel each other's breath on their faces. She looked up at him, gazing into his reptilian, slit-pupil eyes. He leaned in just a bit closer, their eyes drifted closed, and their lips finally connected.
Twilight inhaled sharply and tensed, then seemed to melt in Spike's embrace. He sucked gently on her bottom lip, then moved to the top lip and did the same. Their mouths moved in unison, keeping in perfect harmony. After a few seconds, Spike broke the kiss, pulling away and leaving Twilight wanting more. He opened his eyes and looked at her.
"You know, I never told you, but... I've wanted this for a long time," he told her. Twilight put a hoof on Spike's neck.
"Me too," she said. Then she pulled him into another, more passionate kiss.
Their lips mashed together frantically as Spike released his pent-up passion. Twilight went along, doing her best to keep up with the horny dragon. As the kiss grew more passionate, Twilight felt Spike's long, snake-like tongue pressing against her teeth. She eventually opened her mouth, allowing it access.
Spike snaked his long tongue into Twilight's mouth, licking the insides of her cheeks. Twilight's tongue responded as best it could, trying to wrap around Spike's, but his tongue was much more flexible and ended up wrapping around Twilight's instead.
She moaned into his mouth as they kissed, and she grabbed his sides, wrapping her hind legs around him. His members, both now rock-hard, were brought much closer to her body, and she could feel the texture of their nubs rubbing against the skin between her teats, which were now becoming slightly swollen with her arousal. As she leaned back, she could also feel that her wings had splayed out of their own volition, signifying her arousal in a familiar imitation of a penile erection.
Spike finally broke the kiss and smiled at Twilight with half-lidded eyes.
"You know," he said, "you did something for me. Now it's only fair that I return the favor." Twilight briefly wondered what he meant before he knelt down between her hind legs.
He placed one hand on Twilight's left thigh, sending a shiver through her body as she felt him getting closer to her nether regions. His other hand trailed up her right hind leg, teasingly brushing the fur of her coat as it slid closer to its goal.
Spike leaned his face in close until Twilight could feel his hot breath on her swollen sex. Finally, his claw reached her labia, moving around them just far enough away to keep from satisfying her. It trailed up one side, moving around her clitoris in a clockwise direction. It then moved down and around, passing over her perineum and wrapping counterclockwise around the circumference of her anus. And all the while Twilight continued to feel his steamy breath washing over her pussy.
Spike gazed at the wet organ in front of him and his mouth watered as he imagined shoving his face directly into it. But he had to make sure not to go too fast; Twilight had to enjoy it too. So instead, he stuck out his tongue, the thin appendage gliding ever so slowly toward her dripping slit. It eventually reached the topmost portion of her vulva, and the forked end flicked lightly over her clitoris, causing her pussy to wink and her whole body to shudder.
Smiling at her response, Spike moved his tongue lower, continuing to move his claw around her nethers. The end of his tongue moved down around her labia and up into her slit, then with a slight push, slowly slipped inside her.
Spike could taste Twilight's arousal, his tongue being quickly coated in a thick layer of vaginal juices. As he squeezed his tongue deeper inside her, Twilight gave a throaty moan, and he could feel the vibrations of her voice through her walls. He was nearly overwhelmed by the succulent taste of her juices, sweet and tangy like nectar. Her vaginal muscles flexed, trying to draw him in deeper, but he maintained careful control, wiggling his tongue as it gradually slipped deeper inside her, drawing out more pleasured moans from the alicorn.
Soon, he hit an apparent wall at the end of the tunnel, which he knew to be her cervix. He curled his tongue, flipping it back on itself, and pressed deeper, pushing the tip of his tongue back toward the entrance. She began to wink more frequently, and Spike could feel and taste a fresh flood of sweet juices as her arousal intensified.
Finally, the end of his tongue poked back out of her vagina, nestled on top of itself. It then curled upward, and the forked end reached Twilight's clitoris, which had now become incredibly sensitive.
Spike then pressed his lips to her labia and began to gently suck on the puffy pussy lips. He wiggled his tongue and Twilight squealed in bliss as she was pleasured from both the inside and the outside. The end of Spike's tongue flicked rapidly against her clitoris, and at the same time, the main body of his tongue wiggled against her inner walls, feeling like a warm, living vibrator. All the while, his lips worked the outside, massaging the sensitive mounds of flesh.
"Oh, Spike!" she shouted. "Don't stop!" Spike reached his right hand down to attend to his erections. He wrapped it around the top one, stroking it slowly as he drank Twilight's nectar, while still continuing his ministrations with his tongue. At the same time, he brought his left hand up and placed a claw on her labia, then pushed it inside her underneath his tongue.
Twilight felt Spike's tongue moving like a vibrator and his lips massaging her labia, giving her untold amounts of pleasure. Then she felt his finger entering the fray as well, and everything intensified. He rested the heel of his hand at the base of her tail to keep it steady, then slowly worked a finger into her passage. She squirmed as he began thrusting it in and out of her pussy, first slowly, then with gradually increasing speed. She could feel the pressure building, and she knew that she was fast approaching her orgasm.
"Yes, Spike!" she yelled. "I'm so close! Go faster!" She was winking furiously now, her clit poking in and out from between her labia at lightning speed. Spike grew more fervent, stroking his shaft faster.
He pressed his lips tightly to her pussy, waiting for an opportunity to make his planned move. Her clit winked again, and this time, Spike wrapped his lips tightly around it, sucking on it in an attempt to drive her over the edge.
The maneuver worked, and Twilight screamed in ecstasy as she came, squirting a flood of juices onto Spike's face and hand, who opened his mouth wider in an attempt to catch all of the fluids. He loudly slurped the sweet marecum from Twilight's pussy, drinking down the thin fluid of her climax. It tasted like the sweetest apple cider, and he groaned with satisfaction as it slid down his throat, satisfying him like water from a desert oasis.
When he had drank his fill and sucked Twilight dry, he drew away, slipping his long tongue out of her slit with a small schlick. A thin strand of saliva briefly connected his bottom lip to her pussy before breaking silently. His left hand was covered in the fluid of her climax, and the translucent liquid dripped down his wrist. He brought his hand to his mouth, then one by one, greedily sucked the rest of her cum off his fingers.
Twilight had laid back after her mind-blowing orgasm, basking in the afterglow, but now she sat up on her elbows, looking at Spike with hunger still in her eyes. He noticed her gaze and chuckled.
"You still want to go?" he asked, licking his lips.
"Yeah," she said. Spike grinned deviously and wrapped his strong arms around her. He placed one hand on her flank and the other on her back, and she yelped in surprise as she was lifted into the air. She gripped his shoulders to keep from falling, pressing herself against his muscular chest. He carried her over to the table that he had been sitting on previously, then laid her down gently on her back, taking care not to disturb her delicate feathers.
He stood over her, looking into her eyes as she looked back into his. Then he closed his eyes and kissed her passionately once again. Twilight could still taste the last remnants of her climax on his lips, and it was not an altogether unpleasant taste. In fact, it was actually rather sweet, and though Twilight would probably be loath to admit it, she found she rather enjoyed it.
His left hand grasped her cutie mark while his other hand moved up and down, exploring her body. He reached a pair of small mounds just above her pussy—her teats—and brought his left hand up to join his right. He grasped both mounds of tender, spongy flesh, brushing his thumbs lightly over the erect nipples. Twilight gave a light, delicate moan into his mouth at the soft touch, and her hind legs twitched before wrapping more tightly around him.
As Twilight pulled his body closer, she could feel Spike's woefully neglected dicks rubbing against her, smearing precum on her lavender fur. Her own genitals were also once again dripping with need, smearing her own juices on Spike in turn as they ground their hips together.
Spike stopped moving and pulled his mouth away from Twilight's, suddenly looking at her with a serious expression.
"I'm gonna put it in, okay?" he said. "Let me know if it hurts or anything."
"Okay," she replied. "I'm ready." Spike nodded and pulled back a bit to get ready. He used his hand to guide his bottom shaft forward and touched Twilight's labia, causing her to tense in anticipation. He then pressed forward, the lower shaft spreading her soft pussy lips and entering her silky depths.
Twilight's lubricated walls welcomed Spike's lower cock, the hard member sliding smoothly into her like a hot knife through butter. The soft nubs on the underside rubbed against the back wall of her tunnel, sending a luscious burning sensation throughout her lower body and down her legs. Her tail flicked between Spike's legs, wrapping loosely around his own.
His upper member rubbed against her belly between her teats so that he was essentially teat-fucking her at the same time, while the nubs produced a wonderful feeling of friction against her partially covered clit. Every time she winked, the friction grew suddenly more intense as the nubs came into contact with it, which naturally increased her desire, causing her to wink more.
As she winked her clit, it massaged Spike's shaft, and the adolescent dragon let out a short groan. Twilight's body was responding to him by reciprocating the pleasure he gave tenfold, and it was almost too much for him to handle.
He finally felt Twilight's fur brush against his groin and realized he had bottomed out inside her. He could have sworn that he had been going longer than that, but that was of no consequence. He stood still for a moment, resting inside her, then slowly pulled out until the tip of his lower shaft was just inside her.
He grabbed her cutie mark with one hand and the back of her neck with the other, looking into her eyes as he began thrusting in and out of her. Slowly at first, then faster and faster, Spike thrust his lower cock in and out of Twilight's cunt, driving home each powerful thrust with a grunt of pleasure, which were all echoed by Twilight. She grunted in pleasure, holding Spike's shoulders as he fucked her.
"Oh, Spike, it feels so good."
Spike leaned over a bit further, trying to get a better angle of penetration, and he grabbed Twilight's hips and lifted them slightly. This brought her hind legs up to point almost straight into the air, while also causing her to curl up into a quite vulnerable position. It also had the side effect of hitting a particularly sensitive spot within her. Twilight's pussy clenched and her moans intensified and grew in pitch, which Spike took as positive feedback.
"You like that, Twi?" he asked as he continued to fuck her.
"Oh, yes, Spike!" she moaned in response. "It feels amazing!" Spike's hips sped up more and he put more power into them until they slapped against Twilight's thighs with every powerful thrust.
Twilight could feel the pressure as she approached her second orgasm. Her hind legs squeezed around his waist and she gyrated her hips, trying to encourage him with her body as well as her words.
"I'm close again, Spike!" she whined in his ear. "Rut me harder!" He placed his hands on her shoulders and continued with his powerful thrusting, grunting with the effort of every movement, and Twilight's tunnel clenched once again.
"Oh, Celestiaaa!" she screamed. Her wings flapped wildly in the throes of bliss and she squirted out another gush of pussy juice onto Spike's double members, though it mostly coated the one on the bottom. Though she did not produce as much fluid as the first time, her orgasm was no less intense.
Once the euphoric high had reduced somewhat, she shivered and gasped for air, still holding onto him tightly with all four limbs. He had stopped thrusting when she came, and now slowly pulled out of her, sliding out with a small schlurp. He looked at her expectantly, waiting for her to voice her wishes.
Once she had regained control over her facial muscles, Twilight smiled at him, using her magic to brush a few sweaty strands of hair away from her eyes.
"I feel guilty now for not giving you any satisfaction," she said breathlessly, propping herself up on her elbows.
"It's alright," he said with a smile. "I'm just glad you finally know how I feel about you. Although there is one thing I wanted to try. And you can say no if you want; I promise I won't get mad or anything."
"What is it?" she asked, prepared for the worst.
It was something that he had tried to persuade Apple Bloom to try once, but she had refused, saying that she "don't want nothin' up there." He hoped that Twilight would not do the same, but there was only one way to know, and that was to ask.
"Can I double-penetrate you?"
Of the many things Twilight had been dreading that he would ask, that was oddly not one of them. It made sense, she supposed. Since dragons had hemipenes and mares had two rear orifices, it was only the logical conclusion, but somehow it had not entered her mind until that moment.
She felt a bizarre mixture of emotions at the request, among them excitement, arousal, and anticipation, coupled with uncertainty, fear, and trepidation. Though her mind had mostly been made up on the subject of anal, double penetration had never been at the forefront of her thoughts, considering that she had never been interested in being with multiple stallions at a time. But now that she was being presented with the possibility of having the experience with a single individual, it was rapidly growing to be awfully enticing.
"I don't see why not," she said eventually. "I've tried anal before, but never that. Sounds like it could be fun." Spike grinned, showing his teeth and licking his lips.
"Awesome," he said.
He moved back up to Twilight, who was still on her back, bringing his two dicks once again to her warm nethers. He rubbed his lower shaft along her slit, slathering it with more of her juices, then moved his hips downward, bringing the top member to her pussy. Spike moved ever so carefully, moving his cocks in expert synchronicity so that they teased at both of her holes.
His top shaft spread her soft, pliable labia, which parted to allow the hot organ entrance. He pushed forward slower and more carefully than seemingly any stallion ever could, sliding the thin tip inside her, and he placed a steadying hand on her right hind leg as she gasped in pleasure.
Meanwhile, the bottom member poked against her puckered anus, smearing her leftover juices across the wrinkled skin. The tip prodded at the entrance, begging to be let in, and she remembered her previous experiences and relaxed her muscles. Lubricated by her slippery juices, it slid inside and entered her rectum.
Twilight groaned as the thick rod penetrated her ass, spreading her cheeks and giving her a full feeling. As the draconic cock sank deeper, the full feeling increased in intensity, and she gave a breathy moan of pleasure as she felt the texture of the soft nubs sequentially popping inside her. As it moved, its girth also gradually increased, and Twilight could feel her rump spreading more and more to accommodate it.
At the same time, her pussy was stretched even more than before, Spike's top dick being longer and thicker than the one on the bottom. She moaned loudly in a mixture of pain and pleasure as her elastic walls stretched to allow him entrance, expanding until they were stretched taut around his thick, hard cock.
Her ass was suffering a similar fate. Having hardly ever been worked at all, she could feel her anus straining against the thick rod, but she knew that Spike would do his best not to hurt her, so she was confident that she would be alright.
Spike groaned and grunted as he bottomed out inside both of Twilight's holes, fighting not to cum right then and there at the tightness. He froze for a moment, allowing his loins to cool off, before starting his thrusting.
He started pumping in and out, steadying Twilight's barrel with one hand while holding her right leg in the air with the other. He groaned and lightly squeezed her leg.
"Agh, fuck, Twi," he said, "your holes are both so tight."
Spike thrust faster, and Twilight screamed in bliss as she felt Spike's cocks fucking both her pussy and her ass, only separated by what seemed to be a paper-thin wall of flesh. Her anal walls were struggling to put up with the punishment being inflicted upon them by Spike's pounding, but the lubrication from Twilight's last orgasm had not yet been exhausted, and in fact was even being bolstered by the copious juices dripping down from her stretched snatch. Her burning desire radiated through her legs and despite all that she had gone through already, she felt yet another climax looming on the horizon.
Spike, meanwhile, was feeling pressure in his own loins and knew that his orgasm was imminent. His thrusts began to speed up and become more erratic and soon his thighs were once again slapping against Twilight's, the lewd sounds occasionally punctuated by their moans.
"Oh, gosh, Twi," he gasped. "I'm getting really close!"
"Unh, me too!" shouted Twilight. "Do it inside, Spike! Cum inside me!"
Spike's thrusts became slower and more powerful, smacking Twilight's rump with his full strength, and then he finally gave one last forceful shove, simultaneously shooting two thick loads of cum into her ass and pussy.
Like a broken dam, Spike's hot dragon seed shot deep into Twilight's belly. The cum came in spurts, the first of which was like a flood in and of itself, followed by progressively smaller shots that each still seemed larger than a full-grown stallion's entire payload. The cock stuffed in her cunt seemed to shoot gallons of burning jizz inside of her, and soon her pussy felt like a water balloon fit to burst from the sheer volume of spunk being shot inside it.
Her ass, meanwhile, felt like she had had a barrel of hot cider pumped into it, and the steaming hot, viscous fluid still continued to fill her hole, leaving the insides of her colon soaked and dripping with thick liquid pleasure. The syrupy sperm oozed out of both her holes around Spike's twin cocks, and it was at that point that she could take no more.
Twilight convulsed on the table, her back arching as she experienced one of the most intense orgasms of her life. Every muscle in her body contracted as she rode wave after wave of utter bliss, like a surfer on a celestial ocean. She heard a noise in the distance and realized that she was screaming Spike's name at the top of her lungs.
She finally drifted down from her mind-shattering climax and she gasped for breath, her voice quieting. She breathed heavily for a moment, simply basking in Spike's presence and enjoying the feeling of both his cocks nestled inside her. Then he spoke, and she was broken out of her reverie.
"Holy guacamole," he said breathlessly, shooting her a sultry smile. "You sure know how to have fun." He slowly pulled away from her, and both of his now diminishing erections slipped out of her, dripping snow-white fluid. A thick line of cream flowed slowly out of her pussy and down her perineum. After a couple of inches it joined with the stream coming from her abused asshole, which was slightly agape, and formed a tiny but growing white puddle beside the base of her tail.
Spike knelt down and leaned back in between Twilight's legs, bringing his mouth to her snatch. He then flicked out his tongue and slipped it inside her once again. Reaching his long tongue deep inside her, he reached the reservoir of his cum. He placed his lips on her pussy and sucked on it, drawing the thick wad of spunk into his mouth.
"Mmmm," he moaned as the cum flooded his mouth. His maw was filled with the bittersweet taste of his own climax, mixed with the tang of Twilight's vaginal juices, the two liquids coming together to form a sweet cocktail of pure, distilled sexuality.
He sucked gently on Twilight's cunt, slowly and sensually drinking his cum from her pussy. He groaned in satisfaction as it slid down his gullet, coating his throat in both of their fluids.
When her cavern had finally been emptied, he lifted his head and ran his tongue over his lips, licking the last remnants of ejaculate off of them. He noticed that Twilight was staring at him, and he chuckled.
"What?" She took a moment to respond, being seemingly frozen in place.
"Wow, that was hot," she finally said.
"What, me cleaning up my mess?" he asked with a grin. She nodded. "Well, I can be kind of adventurous when I want to be." He flashed her a wink and she giggled.
He hopped up onto the table and positioned himself behind her, taking her in his arms. She snuggled up against him, relaxing in his embrace, and he gave her a sensual kiss on her neck before lying back against the wall behind him.
After three orgasms in a row, Twilight felt completely drained of all energy and fluids, and she knew he probably felt similarly. So she laid there, basking in his presence, until at length, she fell into a peaceful sleep.

Okay, I know a lot of you other authors can get out a story every two hours, but this is a big thing for me. "Duskshine" alone took me about a month, and I wasn't even writing anything else then. So be happy for me and shut up!
