In retrospective, Twilight should’ve figured out that things would turn out the way they were now weeks ago. Maybe she did but pushed the notion out of her mind? Maybe she was too distracted to put the necessary attention? Perhaps this is the course she desired and thus didn’t act?

“S-Spike, why are y-you doing this?” She asked, her voice barely loud enough for him to hear her as they laid together in bed.

“Doing what?” Spike replied with a nonchalant tone using his left hand to trace her belly using his claw tips. Meanwhile, his right arm ran below the lavender alicorn’s neck while his claws rubbed her neck in a sensual manner.

Twilight had to suppress a squeal as his left hand reached her sensitive teats; his claws kneading them tenderly. “Why are you t-t-touching me this way?”

“Why shouldn’t I? Do you want me to stop?” Spike asked before gently licking her exposed cheek.

“...” Twilight tried to answer him but found herself unable to utter a single word. Instead, she let out a soft moan the moment he lightly pinched one of her perky nipples.

“Thought as much.” Spike chuckled. He then pressed his snout against the back of her head and inhaled her sweet, clean, needy mare scent. “But this is all your fault, Twilight. And you’re going to take responsibility, right?” The mare in question bit her pillow trying to muffle a heated moan. “Yesssss, I can tell your body is more than willing to continue. Your musk is all over the room, Twilight. You smell so good; so needy; so sweet...so female.” Twilight moaned again this time louder.

“Careful now, my precious princess. You don’t want to wake them up, do you now?” Spike asked looking at the other six beds around the large room.

Twilight managed to give take a quick glance to where the rest of her friends were sleeping. She then felt Spike’s strong grip on her lower jaw shift her head enough to allow him to assault her mouth. She was surprised at his sudden action but then melted into the kiss as his tongue invaded her moist cavern; her own tongue now wrestling against his thin, strong, and long draconic tongue.

As they kissed she remembered Spike’s words and knew he was right. It was her fault for not doing anything sooner.

It all started nine months prior with Spike beginning to complain about a burning pain in pretty much his entire body; especially his scales. With each passing day the pain grew more and more until the point where Spike had to be hospitalized due to the pain. The doctors didn’t know what was wrong with him as every test they performed was met with failure. Twilight and her friends had decided to ask Dragon Lord Ember for help, but before they could send the message Spike’s strange disease ended on its own.

Spike came out of his room walking on all fours much like a pony would. He was almost as tall as Celestia, his crest had become bigger but retained their blunt, smooth edge. His scales had turned a shade or two darker with his underbelly scales taken the most noticeable change. There were no traces of baby fat on him as his entire body had now turned into a sturdy, broad form with visible muscles, strong and ample legs, longer claws and a stronger, thicker tail. His face was also no longer rounded, it had more defined features, a slightly longer snout, a pair of visible fangs coming out at each side of his maw, and his ear fins had extended back and became more pointy.

Everypony froze seeing their dragon friend change so much. He took a moment to look over himself, it was then when they also noticed a pair of strong, majestic wings on his back. He then looked at them and spoke them in a soft, breathy voice that still lingered the chirpy tone they all knew. But it also carried a strange authoritarian vibe to it that suited his new appearance well.

Twilight and company had tackled him, relieved to see that he was fine. His new form was nothing like the deformed, lanky appearance he had during the greed birthday incident. Pinkie had thrown that night a massive party celebrating Spike’s health and new form. Rarity, after a couple glasses of hard cider, was the first to admit Spike had turned into quite the handsome stud with all of their friends agreeing to some degree.

Even Twilight was forced to admit Spike really looked good. Really good.

The first couple of weeks nothing really changed in their routine or job performance, except for Spike’s increase in efficiency. He would often finish in half an hour a job that would’ve usually take him four hours or more, so he had plenty of free time on his claws. His newfound free time was spent helping the rest of his closest friends, offering to do some of Princess Celestia’s stacked paperwork or doing odd jobs around town. It did help the rest of the town to calm down and accept Spike’s new form all the more faster.

But things began to change between them in a way Twilight had never thought possible. She caught Spike stealing glances at her rump, nether regions and legs. Although, he didn’t try to hide his exploring eyes over her body. She felt embarrassed, yes, but didn’t step in to stop him; instead she let him continue thinking it was just a phase or something hormonal. She was wrong.

Soon enough he made sure to bump into her every time he walked past her, usually using his tail or a wing to caress her back or touch her cutie mark. When they were walking together around town he did so at her side with a wing over her back. All of that with a small smirk on his face.

Twilight had also noticed the increased attention he had been paying to all the single mares around town. For some strange reason she felt angry seeing Spike interact with so many unfamiliar mares.

Their weekend conversations also changed to be more intellectual as he started reading more books, much to her joy. Those occasions were spent by them lying together in front of the chimney drinking cocoa or coffee, always ending with one of his pampering, deep massages.

Things went like that for a couple of months until she caught him masturbating in his room gawking at Spike’s impressive meat pillar. She was no virgin but her sexual experience was limited at best. Even with that she concluded Spike was longer and thicker than most stallions, even more so than her brother if her memories when she caught her brother in similar situations were accurate. She also knew her big brother was considered ‘big’ by the mares back in school. In comparison, Spike’s penis categorized as a monster with almost thirteen inches long and around three inches thick. His shaft was almost entirely pink, the tip was not flat but triangular and pointed, and there were small bumps and ridges running along the sides of his entire shaft.

She didn’t stayed for the entire show though, but that night she spent a good couple of hours rubbing her pussy numb. She ‘accidentally’ caught him doing so several times over the course of the following weeks. Within that time Spike no longer showed any trace of shame in showing his painfully hard erections around the castle; uncaring for her or Starlight’s presence or their ogling stares. His glances evolved into stares; she felt helpless each time his reptilian green eyes scanned her entire body as if she was a piece of meat. She could feel the hidden hunger behind those great emeralds, and the knowledge made her feel weak, fearful, powerless... desired, wanted, needed.

This night had started with the traditional party/sleepover between her friends. Spike usually joined them but this time he refused, politely offering his services in case they needed them of course, stating he was busy doing some paperwork for Celestia. The night passed filled with fun, games, talks and laughter. The seven mares decided to go to sleep after a few hours and so they did, all except for Twilight.

So now here she was being kissed and held tightly by her number one assistant, her closest friend and little brother in everything but blood, after he had snuck inside the large bedroom, climbed under her covers and began to touch her as he pleased.

Spike pulled back from their kiss leaving her in a daze. Twilight panted for air before she gasped and bit down her lower lip as the dragon’s left hand moved further down capturing her winking, moist pearl in between his finger below his claws. Twilight let out a muffled moan of pleasure when Spike kissed her behind her ear making it twitch.

“You’re getting excited, you naughty pony.” Spike whispered. “You want this, don’t you Twilight? That’s why you never stopped my advances.” He kissed her again while his left claw played with her sensible clit. “That’s why you’re not trying to push me away.”

“Th-that’s not true!” Twilight whispered in protest before she groaned feeling the tip of his tail trace the outer lips of her vulva. “Stop t-touching me, you sick pervert!”

Spike chuckled before catching her winking pearl and giving it a nice, firm pinch making her squeal. “Is that so? If I recall correctly, big sis,” he whispered making her gasp and squirt a few drops of her mare juice. “Didn’t you swayed your hips and tail giving me a full view of your pussy and ponut each time I took a glance at your backside? Didn’t you touch yourself when you saw me masturbating? Didn’t you shiver and trembled at my touch, much like you are now? And I’m the filthy pervert? You’re the perverted one out of both of us, Twi.” Spike chuckled again. “A pervert that can easily use her magic to push me away but does not.”

Before Twilight could respond or protest he lifted up her left hind leg, and in a swift movement placed his penis in between her spread legs; his shaft pressing hard against her soaking wet cunt. She looked down to see his shaft nestled in between her teats and the tip of his dragon cock pressing against below her belly button. For some strange reason she swallowed while she felt her vaginal walls tighten around nothing.

“You want to mate with me, don’t you Twi?” He whispered before licking her horn.

Twilight clenched her teeth hard and closed her eyes for several moments until she let out a defeated sigh.

“Y-yes.” She mumbled out followed by a lusty moan. “I...I want to mate with you, Spike.” Twilight confessed and finally she felt her body relax and enjoy his warmth and tender touches.

“Isn’t honesty a marvelous thing?” Spike teased. “But there’s a bit of a problem, Twilight. You see, I don’t want to mate with you.” Spike then moved his arms around her barrel and hugged her close, his face almost pressing against hers giving her a complete view of his sharp, lethal fangs. Spike felt the mare tense up in fear while she stared at his fangs with her rapid breathing. “I’m going to fuck you, breed you.” He then licked her cheek staining her fur with his slobber. “Make you mine.”

“I came to realise something, you see. I may not be your typical dragon, granted, but I’m still a dragon. You’re an alicorn princess, but you’re still a pony. I’m an apex predator. You are prey.” He used his tongue to lick her trembling lips; her own tongue coming out to meet his for a short lived contact. “And like all preys, you yearn to be dominated by a strong predator such as myself. Usually, an apex predator only wants its prey for their flesh. I’m no different, but for completely different reasons. I don’t want to fill my belly. I want to fill your belly.”

“Nnnngggg!” A loud moan escaped her throat upon hearing those words. Her pearl winking without control

“Sounds to me you like that idea!” Spike teased rocking his hips back and forth in slow, lazy patterns making sure to rub her clitoris all the way through. “And judging by that heavy musk you’re leaking out, you must be cockstarved. When was the last time you had sex, hmm?”

“M--M-My last h-heat.” Twilight mumbled out feeling his left claw travel down again until he took hold of one of her teats. Kneading it, Spike teased her to no end making it harder for her to concentrate.

“That was almost ten months ago!” Spike pinched her nipple eliciting a deep groan from her. “With whom?”

“I-I don’t know...I w-went to the Estrus House.” Twilight replied while she melted into his ministrations.

“You had to resort to a whore house? That’s so sad, Twilight.” Spike kissed her cheek. “But you know something? You won’t be going there anymore. In fact, you won’t need a stallion anymore. And once I’m done with you, you won’t be able to want another stallion.” Spike growled. “But before I do I have to ask. Do you want to be one of my mates, Twilight?” He asked ceasing his actions.

“...” Twilight closed her eyes thinking of all the repercussions her next decision could cause. Finally, after almost two minutes of silence, she moved around enough to kiss him. “Yes.”

“Are you sure, Twilight?”

“...Yes. I-I want this, Spike. I love you...Sweet Celestia I do! Please, I want to be your mate!” Twilight begged moving her hips up and down his rock-hard shaft.

“Do you want me to wreck your tight, soaked, needful pony pussy?”

“Yes.” She pleaded desperately kissing, licking and sucking on his right hand thumb.

“Do you want your womb to be filled with my dragon cum?”

“Yes!” Twilight replied pressing her back against his chest and her round, firm, luscious butt against his groin with each of her eager thrusts.

“Will you give birth to our hybrid, kirin offspring?” Spike asked with a smirk.

“Yes.” She begged. “A-anything you want. Please, buck me.”

Spike didn’t reply in words. He moved back away from her and, followed by a forceful movement, he made her lay on her back. Her hind legs were spread wide giving Spike a clear sight of her drenched nether regions and winking clit. Immediately after, Spike was on top of the lavender alicorn with the tip of his dragonhood aligned with the opening of her puffy vaginal lips.

Spike spread his wings making him look even more intimidating and big while Twilight froze, her heart pounding faster than ever before. He grabbed her left forehoof while his other hand took a hold of her hips, he then leaned down until his lips met hers. Twilight melted into the kiss right away putting her free foreleg over his shoulder, enjoying his long tongue wrap around and pull her tongue as he saw fit. All the while moaning in approval.

It was then that Spike shoved half his cock inside in a single thrust.

“MMMFFHHHH!” Twilight tried to scream, but it was muffled by their sloppy make out session. She felt his hot, throbbing member spread her walls open more than any stallion she had ever been with. The ridges and bumps of his cock adding an entire new level of pleasure mixed with pain she had never felt before. Her insides were clenching hard around his phallus trying to suck him in deeper and milk him for all he was worth.

Spike began to pull out while the spasming walls of Twilight’s pussy tried to keep him inside at all costs. Once a couple of inches were out he thrusted in again until his tip bumped with her cervix. Twilight’s muffled moans causing the side of his lips to morph into a smirk. He stayed inside of her for a couple of moments allowing both lovers to adjust and adapt to their respectives sexual organs.

Feeling confident enough, Spike pulled out until half of his member was still inside before shoving it back inside her wanting, drenched cunt. He could feel her trying to wrap themselves around his hips with little success. Breaking the kiss in time with another thrust he allowed his mare to bite his free shoulder while she moaned and groaned, both in pleasure and pain for being spread so far and fucked so deep.

Twilight shut her eyes close as Spike began to build up a pace by retreating just a couple of inches before shoving his big, meaty dragon cock back into her sopping wet twat. Her mind was in a haze, she could barely form coherent thoughts while Spike fucked her deeper than any stallion she had been with in the past. Despite her clouded mind she still felt him pull almost completely out of her insides, her pussy clenching all around him in protest while her throat let out several adorable whines.

“Ngggg...Spike...wh-what are yOOUHAAHH!!!!” Twilight was cut off as the dragon thrust back inside her, and she heard the slap of his scales meeting with her drenched fur and vulva. It took her a second long moment to realize he had hilted himself inside of her for the first time. “FFFNNNNNGGG!” A scream was caught in her throat as an orgasm rocked her world and sent her mind into a white abyss. She could barely made out a deep growl coming out of the dragon as her plentiful mare juice splashed against his scales.

Spike held Twilight tightly as her spasming body letting it ride out her orgasm. Once it looked like she was coming down from her cloud he began to thrust again. The mare below him could only squirm in pleasure while Spike pounded her with slow, hard thrusts.

“You like it, Twilight?” Spike asked in between thrusts, his breath ragged with panting. “You like how an apex predator’s cock is buried deep inside your pony pussy?”

“Yesshhh!” Twilight replied trying to meet each of his thrust with one of her own. Her wings spread open against the bed.

“You like being bred stupid by your number one assistant?”

“Mnhmmm.” She moaned before capturing his lips in a messy, spit filled kiss.

“Do you want a stallion cock in you after this?” He asked once the kiss ended.

“NO!” Twilight protested managing to free her captive foreleg and lay it over his free shoulder. Her expression one of pure sexual pleasure while her tongue hanged from of the sides of her mouth. “No shhtallion!”

“Good.” He then changed pace into a more rapid yet equally hard rhythm. Twilight moaned loudly while her horn released sparkles of magic. “Because you’re my mate now! MINE!” Spike roared taking a hold of her hips before pulling out of her completely. He then turned Twilight until her face was pressed against the bed while her rump was being held up by Spike’s strong grip over her cutie marks. Unconsciously, she spread her legs as far as she could without giving out her balance and also moved her tail out of the way. “You’re mine!” Spike declared before he shoved his entire meat rod into Twilight’s eager breeding hole.

“SPIKE!” Leaving all pretenses aside, Twilight screamed his name right before another orgasm washed over her form. Another coat of her jizz squirted onto the sticky mess her tighs and their hips had been turned into. Unlike her first climax, however, Spike didn’t stop as he continued to jackhammer his phallus into her convulsing velvety cavern. Her loud, constant moans and pants of pleasure driving him onwards further.

The dragon thrusted in and out of her in alternating rhythms, going from short, rapid thrusts to slow, rough pounding. For an unchecked amount of time he kept going, utterly wrecking Twilight’s sanity as a continuous wave of orgasms shocked her to the core over and over.

Without warning, Spike pressed his larger body against her form forcing her legs to give out and spread completely as lower body fell to the bed. That didn’t deter Spike’s thrusting in the slightest. If anything, it made him increase his pace. He then wrapped his arms around her barrel and hugged her tightly while he grunted and snarled; strings of saliva drooling out of his tightly closed maw landing all over Twilight’s face and mane. His thrust turned erratic and Twilight could feel his dragonhood swell and throb reading itself for his closing release. Much like her own uptenth climax was approaching.

Spike began to thrust into her with bestial lust, repeatedly making the entire bed shake and squeak. He pulled his entire proud phallus out of her moist cavern leaving only the tips inside her, only for him to shove it all the way inside her. The tip of his cockhead aligned with the entrance of to her womb.

Twilight screamed at the top of her lungs while Spike put her to shame with a mighty, triumphant roar that declared her as his mate.

Twilight was forced to lay still while gush after gush of potent, virile, abundant, scolding hot dragon cum was shot into her waiting, fertile womb. She felt her stomach detach and expand with each gush Spike gave into her foal maker. The thickness of his rod creating the ideal dam to keep every single drop inside of her.

After what felt like an eternity to her, Spike pulled out making a lewd, wet shlock like sound. When he finally pulled himself out of her entirely, a torrent of his baby batter came out staining her bed and sheets further mixing with her own marecum.

Twilight didn’t know if she moved to rest on her side or if Spike moved her, that didn’t mattered. What did mattered was her impossibly bloated tummy filled with Spike’s plentiful, sloshing seed making her look several months pregnant with one of his hybrid, kirin foals. Exhausted, battered, and rutted like no stallion could ever hope to achieve, Twilight fell asleep with a satisfied look on her face.

Spike, on the other hoof, was busy spreading Twilight’s gaping, destroyed, contracting, well-fucked snatch admiring his own handiwork. After a few seconds he let out a pleased growl before he climbed down her bed.

“Sleep well, Twilight.” Spike said giving her a chaste kiss on the lips. He then flexed popping a few joints before cracking his neck. He took in a deep breath inhaling the raw stench of sex in the room and nodded in approval to himself.

“Now then.” He said loudly before lifting up on his right hind leg showcasing his cum stained erect cock for a few seconds. He then turned around to face the six remaining mares in the room staring at him with a heavy blush across their faces, wide eyes, and ragged breathing. He could see their sheets and fur stained with their own sweet, sticky marecum. Spike took a step forward making the mares swallow nervously.

“Who’s next?”
