A flame long burning.

Spike let out a low groan as his shoulders sagged from exhaustion. It may have been years since he had a crush on rarity but that didn't mean he stopped going over to the boutique and helping her. The rather arduous task of completing all the dresses for the entire ponyville play (Of course at the last minute) had weighed heavily on her and with sweetie belle out of town on tour there was no one else to help her. Not like he was complaining. He had no chance, nor wanted one with rarity but she was still gorgeous and he still loved to help.

As he made his way back to the library he looked up at the stars and tried to clear his head of the tiredness clouding his mind. They were the same as always, shining so high so perfectly with luna’s moon just above the horizon. They hung like the most beautiful crystals against a black tapestry. That was actually a good idea maybe that would be part of his birthday gift to twilight… He wondered what kind of dress would suit such a style and had the whole thing designed in his head when he realized what he was thinking.

“I'm no fashionista i'm a dragon!” He yelled at the empty road, slamming one tiny clawed hand into his equally petite chest, which tipped his bright pink and blue hat slightly.Spike straightened it and stood tall. He let out a breath and laughed at himself. “I guess Rarity’s fashion sense has rubbed off on me after all this time.”  And her penchant for talking to herself. He pushed the thought from his mind and and turned the last corner to home. He imagined his bed so soft and comfy his blankets so warm he could almost feel it already.

Spike crested the stoop and entered the library to find twilight sitting away from him reading a book. Soft light from several candles dotted the library. The large alicorn was facing away from him, her rump upon a large pillow that was almost too small for her frame. She stretched her wings out suddenly, holding them rigid before pulling them back tight against her body. It occurred to him just how huge they had gotten over the years. Other than her size, she still looked exactly the same. She had let her mane and tail grow out equally with her new proportions upon spike’s insisting. Hints of translucent sparkles had begun to dot her mane over the last year. Other than that her horn had grown longer and she had oddly started wearing long dresses recently. He chocked it up to finally getting a sense of fashion but perhaps there was more to it.

Her head was low and his entrance did little to break her from her reverie. Spike grinned and tip toed as best as his clawed feet could allow. He wrapped his claws about her eyes from behind and whispered “guess who?” Twilight immediately lifted herself off the ground with a surge of her wings, sending spike flying across the library. Using her magic to teleport the book away in the same movement. A litany of out of character curses were mumbled as the alicorn righted herself and looked around to find spike against the wall covered in fallen books. “Oh spike its just you. You scared me half to death!”  Spike shook the ringing out of his ears and started picking the books off of himself.

“What the hay twilight why did you freak so much? I told you i was coming home after i helped rarity.” He paused and saw an uncharacteristic blush across his “Mom’s” face.

Spike tilted his head slightly. “Uh what were you reading?” Spike asked quizzically.

The purple alicorn crossed her back legs and hastily responded. “Nothing. Just a book. You know with words.” She planted her face in her hoof.

Spike just shook his head and went about finding a gem to eat before bed. Twilight was into another great book and he likely wouldn't hear the end of how great it was until well after he should be asleep. As he rummaged through the cupboards he struck up a conversation. “You would not believe my day twilight.”

As spike started recounting the day’s experiences twilight breathed a deep and muffled sigh of relief. Trying to make herself look slightly more relaxed as she tried her best to keep her lower half out of sight.

As she listened to spike talk about his day she watched him move about the kitchen, his hips swaying slightly going from cupboard to cupboard as he spoke. When he had given up looking around the cupboards he leaned down low to look in under the sink for his not so secret stash. He sure has grown up over the years. Very tall, slender…. feminine. Twilight tilted her head to get a better look. And just look at that ass, i mean it was wide which was a point of concern for the dragon who was worried ponies were going to start thinking he was fat. Not overly large but enough to give him a slight pear shape. The alicorn looked down and blushed quickly magically grabbing a pillow to cover herself with as spike turned around still recounting the day.

“And then she had the gall to use a simple blue instead of the teal that i suggested.” Spike threw his hands up like rarity had gravely insulted him. “Can you believe that?”

Twilight tried to recount what he was talking about but came up with a grand total of nothing, something about floral patterns? Quick twilight think of something. Hmmm smile and nod just smile and nod. Spike’s confused look made twilight rethink her brilliant strategy. “I mean no, i was agreeing with you.” Brilliant twilight.

Spike threw up his hands in defeat. “Exactly! I mean if someone as unfashionable as you. no offence twi, knew that than i mean it should be obvious.” His angry retelling had grown from simple hand motions to full on throwing his hands up in dramatic exasperation, which ended up tossing the gem he had been chewing on behind him. “Darn it.”

Apparently his over dramatic telling of the grave errors rarity had perpetrated upon all pony kind with her poor sense of style had loosened his grip. Twilight’s face flushed red instantly as spike leaned down to retrieve his gem. His short form fitting pants he had made himself rode low revealing a very skimpy thong poking out. It was bright red, not just deep orange but blood red. Oh my celestia how it perfectly framed his gorgeous ass. The slight roundedness of it was accentuated immaculately by that thong.It was lacey just like his shirt, red on a light pink you could see it a mile away sticking out of his mainly blue ensamble. His shirt that had stuck so tightly to his chest lifted slightly from the hem of his pants. That silly shirt he had told everyone would be “The trend of tomorrow” with its lace patterns that made up the majority of the shirt. It was so revealing but without showing more than a centimeter of skin or more between the lace. Most ponies thought it was langerie. Twilight wiped a stray drop of blood from her nose and let her magic wane for a second as he turned back around gem in hand.

“Ugh, im so clumsy lately why just today i damn near tossed a needle at...Uh twi” He pointed a claw at her crotch where a rather large lump of flesh poked out from under the pillow she had hastily used in attempt to cover it.

Twilight blushed even redder with embarrassment, she covered her face with the pillow to hide from the shame only to realize she wasn't hiding HER shame. As she readied excuses she moved the pillow away expecting to see a horrified spike instead she was greeted by a mesmerized dragon eyeing up her package with the same interest as a huge ruby. He let the gem fall forgotten to the ground. Twilight stammered “I'm so sorry spike its the whole princess thing she said that it would just grow later but i didn't think it would come so early.” Her words spat out a mile a minute but they didn't even seem to be heard by the shocked dragon.

“Uh yeah twi what you said, princesses and stuff.” Spike edged closer leaning down slightly. His eyes never leaving her quivering nearly two and a half feet of erect cock.

She replaced the pillow only to realize it could no longer even cover it completely. Suddenly an idea jumped into her head, and out her mouth without so much as a second thought. “You want to touch it?” Wait, why did i say that. But its so hard and should only be grown when i'm a full alicorn it looks so freaky-.

“Yes! I mean i'm a bit curious, is it real?” He poked the tip with a claw making twilight gasp at the sudden touch. “Oh wow it is real. I never touched a real one… well except that one time.” his voice trailing off.

“Wait what was that?” twilight stood up slightly, making her rigid cock stand at full attention and bob slightly in front of spike. “Spike the dragon have you been screwing some other stallion?” Wait why did i care, i have always suspected and accepted it but why am i so protective.

Spike withdrew his hand and ran it over his head, combing back his scales and tossing his hat on the table. “Well no but well.” He looked down at the ground trying to hide in it, if only he could dig straight through the ground maybe the mole ponies would hide him.

“Go on spike” Twilight commanded. Using a tone usually only reserved for if he misbehaved or forgot to give her a letter from the princess.

Spike sighed and in a shaky tone told the story. “Well you see one time a few weeks ago i was helping applejack cus apple bloom was sick and i guess it got late cuz when we were done we sat down for a cider. Wait you werent supposed to know that! It was just one i swear.” Spike looked up at twilight but she didn't seem fazed in the slightest. “Well uhh big mac had more than a couple and he went to the barn after apple jack was teasing about liking caramel for some reason. I didnt get it, i mean who doesn't like caramel? I was curious so i followed him. Well he was.. stroking his umm, shaft in the barn like right out in the open.” Spikes face became another two shades redder as he continued. “Well he saw me and just motioned me over and suddenly i was touching it and it was really warm but i got scared and left thats it I swear!”

Twilight just looked him up and down, noticing a slight bulge in his pants that made her smile. “So i have 2 questions spike.” Twilight stood up, wings outstretched. Spike didn't seem to notice any of this, only the hard erection bouncing against twilight’s soft stomach, he was caught off guard by the sudden change of tone and looked up, making him look her in the eyes.

“Yeah sure of course twi whatever you want.” Spike blurted out a bit too quickly.

“Number one, who was bigger?” Twilight asked flatly.

Spike blanched and mentally had to size up the two penises in his mind. This did little to to dull his tent making. After a few long seconds he gulped and said. “You.”

Twilight pumped a hoof in the air triumphantly. Wait, why was that important? She shook her head suddenly and trotted closer to spike. Her hard member was just inches from spike’s face. “Number two, do you want to do more than just touch it?” Wait this was a terrible idea why am i being so forward i didnt even think this through. But then again i've been thinking about this for months.

Twilight bit her lip in anticipation while her head whirled with thoughts of all the lines she was crossing. Images of spike running away or worse telling everyone about her strange predicament fueled her panicked thoughts but they were quickly silenced as a small girly squeal spilled out of spike’s mouth, which suddenly lurched forward and wrapped around the head of her cock. Twilight nearly fell forward from the sudden pleasure and shock. In an instant such panicked thoughts flew from her mind the second his lips touched her stallionhood. Her cock head twitched suddenly and while the dragon desperately tried to cram it into his mouth. She looked down at spike as he did his best to get his lips around her wide flared cock. “Slow down mister, a simple yes would have sufficed.”

Spike hardly noticed but slowed down and meticulously wrapped his lips around her cock and slowly began to run his tongue along the ridged cock head spreading a fine layer of spit across it. “Umf yef wufefer.” Spike muffled through twilight’s cock. Which roughly translated to. “Unf yeah whatever.” The alicorn shuddered as the vibration echoed down her cock.

Spike quickly stuffed as much of the cock he so desperately craved into his mouth. His long tongue ran along all sides slathering it completely. “Oh my celestia spike. How on earth did you get so good at this? Something is happening, its gonna uh uhhhh.”

Spike pulled back just in time to catch the first spurts of cum in his mouth. The huge equine cock in his mouth twitched and jumped with each shot. The back of his mouth was coated as each blast of cum seemed to be fired out of a party cannon. His throat was quickly filled with cum and he did his best to swallow every drop. After nearly a minute of spurting spike felt like somepony had poured a whole barrel of cider down his throat. Finally it stopped and twilights hooves that he didn't remember being placed there, lifted from his shoulders. “Sorry for finishing so quickly i'm not used to it and i was looking at some well pornagraphic material before you got here” She looked down and noticed something odd. “Oh my spike just look at you.” Twilight exclaimed with a giggle, pointing a hoof at his stomach.

Spike’s usually tight shirt was stretched thin over his bulging stomach. The fabric spread spread dangerously over his large cum belly. Suddenly he belched loudly, the taste of cum thick on his breath.He hardly had the time to taste at first, only to try and swallow load after hot load. She tasted like salty strawberries he thought. He took a moment to savour it, roll it around in his mouth. He swallowed what little was left with a gulp and wiped his lips and stuck his claws into his mouth sucking the jizz off.

“That was… great, you're sooo big twilight.” Spike licked his lips again and finished cleaning off his claws with his tongue. He looked up at the suddenly very quiet alicorn, very embarrassed at what he just did. “I should have asked first it was just so.” Twilight’s hoof against his lips stopped his thoughts in their place.

“You did exquisit my little number one assistant.” Twilight’s reassuring words and wide smile did wonders to ease his embarrassment. “But i think i need more.” her grin took on a more devilish smile which flooded spike’s face with a deep blush all over again.

“Well i don't think you would, ya know.” Spike made a gesture with his hands to indicate just how big she was, never mind just how wide the head was. Iit didn't even seem to get soft very much, it was noticeable but still it stood, drooping only slightly. “Fit”

“I have just the thing my mare, go lay down on the bed and take off those pesky clothes. I will be up in a second.” Twilight purred into the young dragon’s ear, sending his heart among other things fluttering.

Spike turned around and took off up the stairs wondering what Twilight had in mind. As he raced up the stairs twilight watched that gorgeous ass of his bounce, his hips swaying slightly as he shifted from foot to foot.

Her stallionhood threatened to rise up harder than before. She quickly calmed herself and set about finding the jar she was looking for. After a few seconds she found it, popped it open and covered her half erect cock in the lubricant she accidently made a week earlier while trying to make something that would help grease up wheels until the liquid touched the ground and became water. It was almost a gel but still runny it clung to her flesh and glistened under the candlelight.The liquid was cool, a bit too cool her cock almost seemed to shiver under the strange sensation. After a quick inspection that it was significantly lubricated she unfurled her wings once more and gently ascended to the top of the stairs.

There waiting for her was a completly naked spike who was looking back over his shoulder at her. His hands rested on the bed, lifting his ass up for her. Those slender long legs were just barely off the bed, presenting his gorgeous ass for all to see. He wiggled slightly as the draft made by her wings washed over him, his twin  cocks twitching slightly in the light breeze, hardly visible beneath his large posterior.“Well um i hope this is okay twilight.” Spike whimpered. A minute had passed and his nervousness finally boiled over enough to say something.

“Your… perfect spike. Perfect.” She slowly walked over to him, her cock audibly slapping against her stomach with each step leaving a small trail of liquid as the lube left splotches across her belly. Spike watched, eyes transfixed, it was only semi hard but it was almost two feet long and about as thick as his wrist.

“But twi how am i… ya know gonna get it… In me?” He looked away embarrassed, scratching his head with a claw.

She settled behind spike and let her cock rest against his ass and pretty much the rest of his back. “Don't you worry spike. I will put it in now before i'm fully hard and then you can…” She stumbled for the right wording... “Stretch.”

Spike blanched at the mere thought of that monster getting stuffed inside him. The image of just how large it was minutes before made him question the logistics. His cocks twitched against the bed and his hole clenched at the thought. He looked back and in a voice hardly above a whisper. “Im ready.”

Twilight positioned her hooves and guided her semi hard cock against spike’s virgin ass. One hoof lifted his tail out of the way while the other struggled to jam the monstrous penis inside him. As she struggled she thought for a second it might not be able to fit even half hard. Than just a little bit slipped inside and her weight she had been leaning against him with carried half of it inside him in one swift motion. Twilight's low groan was drowned out by spike’s high pitch squeel.

She put nearly all her weight behind her cock and quickly pushed more inside spike. It took longer than expected but slowly her huge cock pushed further and further inside him. Seeming to bend as it reached an impasse. Spike groaned and grabbed at his cum belly as he felt inch after inch crawl deeper inside him. Minutes and many heated moans later he finally felt it stop. Oh god she was finally balls deep inside me. Spike breathed a sigh of relief as he realized he wasn't sure if he even had anymore space inside him left. But twilight shifted suddenly and shoved again making his eyes nearly pop out of his head. Thats not all of it! Suddenly another half foot of cock charged deeper inside him making him struggle to contain an orgasm. He moaned and whimpered as he felt his little cocks spurt against the sheets and muttered twilights name over and over as his first orgasm of the night finally subsided.

“Did you cum already my mare?” Twilight grinned as she teased him. Spike didn't even have to be looking at her to know she was grinning and he whispered a faint yes back. “Louder spike, tell me what made you cum.”

Spike hid his face in his hand while the other kept him propped up on the bed. “Your thick cock made me cum its just so huge and all the sloshing of your cum inside me already made me cum.” He turned his face against the bed and in a hushed tone added. “Not like you weren't faster than me, you giant.”

The alicorn laughed, ignoring the last part, giving one last buck as she rested the entirety of her cock inside her “mare”. “Look at me, i wanna see my mare’s eyes as i fuck her.” Spike hesitantly turned to meet her gaze. Her warm violet eyes, filled with love and edged with lust melted away his embarrassment. “There we go. Relax spike just relax.” Twilight accentuated the words as her magic wrapped around his quickly rehardening member.

“Oh my, are you ready again my mare? So very greedy for all my love. If i didn't know better i would think your a changeling” She leaned further down and gave him a kiss on the lips. Spike closed his eyes and reveled in the kiss, letting twilight’s tongue enter his mouth. As suddenly as the kiss started it was over. “Oh my... can you feel that?”

Spike’s eyes went wide as he realized what twilight was talking about. The massive cock that had taken up residence inside him had pulsated suddenly as it began to harden fully. Twilight’s resolve had melted under the unending pleasure of his tight hole.The flared head pushing up against the deepest recesses of his body. “Oh god twilight you're so fucking huge. I can feel you fill me up so deep.” Spike looked down at his cum filled belly and for a second he swore he could see the faint outline of massive cock against his stomach.

but even as twilight hardened and extended to full length she didn't move. The huge invader rested firmly inside him. Several agonizing moments passed and he began to get antsy, trying to push back against the massive cock inside him. He twitched and shifted around trying to get twilight to move but she just lay atop him moaning and grunting as she grew accustomed to the feeling. “C'mon twilight fuck me.” He whimpered as he the large pony held him tight.

“Not just yet, i want to know some things first. What are you? Whose mare are you?” Twilight’s whispered into his ear seductively. “I won't move until you tell me what i want to hear.”

Spike groaned and tried to grind his ass but was held down as if twilight was petrified by a cockatrice. “Twilight please just move… please?” He let out a slight sigh “I'm… A mare, your mare. Please just fuck me. I need it so bad i need you to fuck your mare.”

On cue twilight began pulling out slowly making spike writhe with the feeling. Like his whole body was being pulled inside out. After several agonizing seconds of near emptiness that had spike scrambling to push back only to be stopped by a firm hoof against his back. The alicorn let out a lusty moan and shoved her cock back inside him in one swift move. Spike groaned and let out a sharp gasp of air as the massive intruder was stuffed back inside him. Where it should be. This is a million times better than that dildo. He blushed at the thought but was quickly brought back to reality as the large pony over him leaned into him and started thrusting.

“Oh sweet celestia thats good, your ass is so perfect spike like it was made for my big cock” Twilight giggled slightly, never slowing as she teased spike. “If i didn't know better i would think you've already… broken in this hole”

Oh shit can she read minds. “I may have a small *unf* dildooh goddess that  feels good.” His reply quickly devolved into soft panted moans.

“I know, i found it awhile ago while cleaning up” She said, watching his face get even redder. “Your too fun to tease my little spike!” Her hips suddenly surged forward, making him squeal.

Spike’s arms quaked. The long day combined with this heavy alicorn on his back had taken its toll. He collapsed on the bed letting himself lie completely flat not caring as his cocks got smooshed between his stomach and the bed. The immense pleasure from being filled so completely outweighed all others. That huge cock filling every inch of him, hitting all the pleasure zones. He could feel it building already.The pressure and friction on his cocks were enough to bring him to orgasm for the second time. He stifled a moan with his claw holding it in.

“Spike are you cumming again? i can hear your cute little girly moans. If you haven't noticed i'm balls deep inside you right now” Twilights face lit up as her magic flared to life. In an instant spike’s orgasm stopped making the cum seem to freeze.

He looked up in confusion. “What did you….” His shock vanished as he saw her magic. Well if thats how she was going to play.

The slap of their hips connecting became louder as spike pushed back against the huge equine ccock. His whole body shoving back against her, making every little millimeter of cock to be pushed inside with every thrust. He smiled devilishly as he heard twilight moan loudly and tilt her head up, making her magic falter slightly. His orgasm returned but was still held on the very edge. His balls burned with need, he could feel his cum needing to escape.

His tail snaked up between her legs and wrapped around her large balls holding them nicely, massaging them as best as his scaly skin could manage. He was rewarded with the feeling of a tongue softly rolling onto his head as twilight let out a deep moan. He could feel she was close. Her thrusts were short, deep.

“Spike i'm about to.” Than he squeezed. “Eep.”

“About to what?” Spike teased as he held her balls in a vice like grip. “Going to cum? Only before you let me.”

The large alicorn attempted to move her hind legs only to find that she would fall off the bed if she moved much. Her fore legs couldn't reach far enough to loosen his tail. Her magic simply wasn't enough. Too many distractions to split it. “Why don't we cum together my little mare?”

“On 3?”

“3”

“2”

“1”

As twilight’s magic lifted so too did spike’s grip on her grapefruit sized balls. All at once the flood of pleasure returned. Twilight became rigid as spike pushed back against her. Their bodies connecting as their orgasms returned with fury. Spike came first, his dual pricks spraying the bed sheets with a thick layer of cum, adding to the previous orgasm. He didn't care he layed on it all the same, letting it cover his stomach and chest in a fine white layer.

Twilight’s orgasm was even bigger than before. Each powerful shot surged deeper and deeper. She bit her lip as her orgasm peaked. Spike’s stomach distended even more, with each shot it got bigger. He went from having a little belly to a full on 9 months pregnant with twins by the time her orgasm died down.

Twilight had long since collapsed onto spike. Nearly a half hour had passed and still little squirts could be felt. Finally it stopped and she felt her flared head begin to soften. Spike had cum two more times since then, emptying his balls onto the bed and all over himself. He didn't care.

“Should I…. Pull out?” twilight asked a bit embarrassed at the long silence.

“Can we stay like this? Just a bit longer.” He looked over his shoulder with a pleading look on his face.

Twilight could not say no to that face and relented. “I think that can be arranged.” Her horn flared to life and she lifted them both up and onto the bed onto their sides. Her massive cock never pulling out in the slightest. As the settled in he pulled the blanket over them both. They had a lot to clean up tomorrow but right now this moment was perfect.
