Dragon adulthood has reached Spike, and the change comes with new emotions and sudden desires for Twilight

Twilight had always seen Spike as a beloved, trusted friend, but as of recent her feelings have been treading into areas beyond simple friendship. With Spike turning eighteen, finally reaching maturity for dragons, his body and libido had shifted massively. Far taller, more muscular, and constantly eyeing up her and her friends, Spike had been getting Twilight worked up more than she'd like to admit.

And preferably never admit.

Though, even with her giving her best efforts, it might just be too much to contain. Sometimes, things like this, are just destined to happen.

A Lustful Change

Fumbling through various books within her castle’s library, Twilight was dutifully at work. Carefully sorting her beloved pieces of literature alphabetically, she stuck her tongue out as she focused. There were many things that made her happy, but organizing her near endless collection of books was certainly near the top. Arcanely sliding the final few dozen into their proper places, she smirked and nodded. Though she usually worked hard to keep herself busy, lately she had been doing it specifically to distract herself. Some rather scandalous thoughts had been running amok in her mind for the past few days, and she was doing her utmost to get away from them. She wasn’t one to let lust, heat, or anything else get to her usually, but a certain development in her life had made things go awry.

“Isn’t that - like, the twelfth time you’ve organized them?” a deep, masculine voice called from behind.

Her eyes went wide, as she whirled around to face the voice she knew well. Standing in the doorway towering over her own height now, was Spike. He leaned against the wall, arms crossed as he eyed her curiously, those green eyes shimmering into her own. He was far, far taller, much more muscular, and immensely enticing compared to the Spike she grew up with, but it made sense as to why. He had attained dragon adulthood only a few months ago, and with that came a series of developments. Reaching full maturity, he had grown exponentially, his voice deepened, and his behavior had…shifted.

It hadn’t taken long for her friends and her to notice how he was acting once he turned eighteen. It was as if his libido spiked to new heights, and they oftentimes caught him eyeing up their flanks and more. Oddly enough, they had all seemed in agreement that it was strangely tantalizing, and, even though they’d pretend to not notice him staring, they’d frequently move their rumps, fidget their tails, or part their legs in manners to tease him. Twilight herself was guilty of the same, finding the idea of her lifelong friend lusting over her painfully arousing. He simply had an aura to him, so domineering and bulky that he could manhandle any of them with ease, and though none would admit it, she was certain they’d have a lay with him whenever possible.

Spike was, as always, sheepish as ever. It wasn’t uncommon for one of them to taunt him with a glimpse of their goods, just for him to go red in the face and excuse himself soon after. Rainbow was the first to eye up the massive dragonhood he had on him, and then the domino effect settled in for all of them. Whenever he wasn’t around, it became more and more frequent where the topic of him and his member arose, with each of her friends clearly lusting over it. They did question Twilight on how she was handling living with such an impressive stud around, but she did her utmost to dismiss it whenever possible. Though, with each passing day it was becoming harder and harder to ignore him. Even now, as he stood in the doorway, he had a slight blush on his muzzle, more than easily telling her that he was just eyeing up her flanks.

“O-oh - Spike, I didn’t see you there!” she stammered, fidgeting her wings at her sides. “I’ve just been really enjoying organizing these books is all!”

It felt almost surreal, the changes he had undergone, but this was now her reality with her lifelong friend. He was horribly attractive, sweet, and more, creating a blend of traits that called to her and all her friends’ depths. She grimaced, feeling her tail begin to twitch. This wasn’t to tease him, nor was it a conscious decision, her body itself simply acted on its own. She couldn’t deny the lust that had been building up for him over the last couple weeks, but she was determined to try and remain stoic. Sure, her friends were craving him all the same, but they didn’t grow up with him. It felt somewhat wrong to her if she and him had a rut, assuming he’d even say yes, but the concept of it being so taboo also aroused her more than she liked to admit.

“Uh-huh -” he replied, unamused by her poor excuse. “I know Twilight Sparkle, and even she doesn’t like organizing books that much.”

Twilight pouted, looking back over her shoulder at the bookshelves surrounding her. “Is that so? Well the Spike I know wasn’t always this big, muscular stud! So maybe creatures and ponies can do things differently after a bit!”

“You think I’m a stud?”

Her eyes went wide, a blush snuck into her muzzle, and she gnawed her lip. She hadn’t even realized the compliment she let slip past her lips, her lustful thoughts giving her a lapse of judgement. It was wholly uncharacteristic of her, but her mind was awash in carnal thoughts she did her best to ignore. She wasn’t even in heat yet his mere presence around her made her feel like she was. Everything about him called to her bestial instincts, and her logical mind continued to fight against its primal counterpart. Though, it seemed to have lost this battle, as she had let slip one of her yearning thoughts about the dragon.

“I…I…” she stuttered, a brief nervous sweat running down her face. “Y-yeah! I mean, I know you, Spike. I’m sure you’ve been checking yourself out in the mirror nonstop since the change happened!”

Spike rubbed the back of his head, chuckling. “Okay, fair point. Just didn’t expect to hear it from you is all.”

Furrowing her brow, relieved she managed to recover, Twilight rolled her eyes. “Spike I have always complimented you and told you how amazing you are! Why wouldn’t I know that you’re like this?”

“I dunno.” He shrugged. “You and the girls have been complimenting me on this body a lot lately.” He gnawed his lips, drifting his eyes towards Twilight’s rump. “Makes me feel bad since I don’t compliment you guys ever really.”

“Except Rarity,” she replied, deadpanned.

“Okay, except Rarity,” he grumbled.

She caught his eyes drifting towards her rear, a tinge of arousal growing rapidly in her depths as he did. She instinctively turned a portion, giving him a better view of her plump rump, even if her mind told her it was better not to. That yearning deep within her began to brew again, and she felt her marehood begin to show the signs of her growing lust. The tension her friends had between him had been escalating bit by bit for them all, and for Twilight it seemed to be reaching its apex.

There was nothing stopping her from outright asking him if he wanted to sample some pony pussy, but she had no real idea how he’d react. From what she knew, he was still a virgin, and if he was offered to have his v-card taken away from him by what was almost his sister, then she could only imagine how he’d respond. Still, those thoughts were growing all the more potent as their brief discussion continued, and her tenacity was yielding to her lust. All the comments her friends made, the way he looked, and the fact that their bond would evolve all the more made for the perfect blend of primal desire.

“Uh - Twilight, you okay?” he asked, raising a brow.

She perked up, snapped from her derailed thoughts. Laughing nervously, she dismissively waved a hoof. “S-sorry! Just was…thinking over this week’s schedule really quick! Being cooped up in this castle all day makes it hard to clear my thoughts.”

“I hear ya,” he agreed, smirking. “Ever since I’ve been like this, I like being out all the more.” His eyes went wide, as he smiled over at her. “Hey, you don’t have any plans today ~ right? Nothing with the girls?”

She tilted her head, curious. “Today’s supposed to be my break day, so I’ve got nothing on my agenda. Why?”

“Why don’t we go for a walk?” he asked, pointing a talon at her. “You’re clearly thrown off by something, I know you well enough to see that. Maybe some fresh air will clear your head.” He glanced at her flanks again, biting his lip. “I know I could.”

He was awful at hiding his perverse gaze from her, be it because he was so naive to these new feelings or that dragons simply had no sense of subtlety, but a growing part of her loved it. So openly being ogled by him of all creatures lit a flame of passion in her groin. She knew full well she had a rather thick set of cheeks on her, be it from her friends’ own words and the many, many studs she caught peering at her flanks, but when it came to him eyeing them up, it felt special. Gulping, feeling her marehood give an enthusiastic wink, she became fully aware of her dwindling resolve. The gradual buildup from the past few weeks, and the fact that she lived with him, was beginning to chip away at her insistence on hooking up being far too outlandish.

“A walk s-sounds nice!” she blurted out, forcing herself away from the thoughts stirring in her imagination. She levitated a set of scrolls, scurrying over, nudging him out of the way, and hastily trotting down the hall. “Let me just put these in my bedroom, okay! Okay!”

Spike was well aware that the tone of voice she was using right now was the one she had when she was panicked, stressed, or overthinking, but his focus wasn’t on that at all. Having peered at her rump several times already, he had worked himself up, but now, as she walked past him, it had become all the more intense. Each step made her flanks subtly jiggle, not to the extent that Pinkie Pie’s would, but still more than the average mare for sure. Not only that, but when she gently pushed him out of the way to run down the hall, the arousing, sweet scent of lavender had wafted into his sinuses, sending a thrilled shiver down his spine. Watching as she continued making her way down the hall, he kept eyeing those bouncing asscheeks of hers, licking his lips as his draconic instincts funneled into his mind.

Twilight, on the other hand, was hastily trotting over towards her room. Rounding the corner and going into a full gallop, she ran all the way to her personal chambers without a second to spare. Tearing open the door with her magic, she slipped inside and slammed it shut behind her, resting her back against the door as she heaved air into her lungs.

“Come on, Twilight, get a grip!” she groaned, facehoofing herself as she shook her head. “You can’t! These stupid thoughts are wrong! It’s wrong! Him and I…t-that would go horribly!” She let go of the scrolls, letting them fall to the floor around her as she gnawed her lip. “But the girls all seem to feel the same about him…so is it really wrong? I mean, any of us would love to get dicked down by his fat, thick, throbbing…” She shook her head intensely. “N-no! Gah! I can’t even think straight!”

She rested her head against the wood door behind her, slumping down a bit as she gave an annoyed sigh. The conflicting thoughts in her mind were clouding her logic, making her inefficient, and, if she let them continue, she knew she’d never get to have any peace. Either go for it, or don’t, those were starting to seem like the only two options available to her. Though it was impossible to decide, one side of her wanting to avoid it but the other believing it was inevitable. She parted her hindlegs, looking down past her hefty bosoms. A bead of her essence trailed down her inner thigh, her arousal made manifest by her cunt drooling with her lust. Scrunching her muzzle, her blush grew further.

Spike. Spike made her feel like this. The thought would’ve been downright uncanny to her not even a year ago, but now it felt so natural. She had gotten off to the thought of him and her rutting for the last few days, after hearing Pinkie so shamelessly admit to doing it herself. At first she figured it would’ve turned her off, but after the first time, she had unlocked a whole new realm of fantasy. Imagining him while she rubbed herself had proven to be a euphoric experience over the last couple days, and she was growing downright addicted to the thought of the carnal fury he could unleash upon her.

Slowly sliding her hoof downwards, she paused. If she was going to get a quickie out to clear her mind and avoid drooling her essence behind her as she walked, she had to do more than just use her hoof. Shakily rising up, locking the door behind her, she awkwardly trotted over towards her dresser. Pulling it open, she levitated a large, green, silicone dildo from within it, holding it before her eyes as they danced with wonder. It had been a recent purchase, but it was one she had been using plenty. The coloration, the fact that it had a knot, and the sheer size of it reflected her deep desires, as it was entirely purchased with Spike in mind. He was simply too enticing for her to ignore entirely, and she had hoped the artificial dong she had would’ve at least quelled some of the desires she had - regretfully, it had only made things all the worse for her, with her now becoming painfully fond of riding a cock with a knot, though she hadn’t had the chance at the real deal.

Yet...

She shook her head, cursing herself for once again thinking about doing the real deal with Spike. She didn’t want to upset him, and she didn’t want to risk things with him as a friend, so she had to settle for the next best thing. Shifting herself, not wanting to get on her bed and soil her sheets, she laid on the ground on her side. She lowered the dildo to the ground, pressing the suction cup end of it onto the floor and letting it settle with a quick pop. Shrouding the tip of it in her magic, she shimmied her rump, bringing her marehood towards it. Bending the dildo, she slowly and sensually dragged her slit along the shaft of the artificial member, letting out a deep, throaty moan as she did. Coating it in her lust, she ground her marehood along it for a few more seconds, feeling her body dancing with pleasure as she did.

Though, her intentions laid elsewhere, as she once again shifted herself, now bending the dildo to aim its tip at her asshole. She didn’t mind filling her pussy with some bliss, but today she simply craved some affection for her perky ponut. Coasting the tip of the dildo closer to her backdoor, she felt it give an enthusiastic wink as the head of the dong teased it. Prodding herself for only a moment, she took a deep breath and pressed herself back. Immediately, a surge of pleasure ripped through her body, coaxing an unbecoming moan from her lips as she shuddered with delight. Her marehood winked needily, wishing to receive the same penetrating pleasures her asshole was being given, but it didn’t take long for her entire body to begin shuddering with bliss.

Thrusting her ass back, she began to routinely fuck herself on the silicone member, losing herself to her lust. Each and every thrust back she made, she pictured it as Spike railing into her with reckless abandon. Filling her depths, stretching her walls, gripping onto her hips as he rut her with everything he had, it was all she could think of while she pleasured herself. She knew deep down that his actual cock would be a magnitude more amazing. Warm, throbbing, and bound to pump a hefty amount of cum into her, it was far beyond what her toy could afford. Still, the shameful mockery of the real deal still disposed upon her the euphoric sensations her body needed to have quelled.

Her rump jiggled with each motion she made, her cheeks clapping around the dildo pummeling her asshole. Her motions intensified, her moaning grew rapid, and she felt her body begin to grow warmer and warmer. Minutes went by, as she was lost to her bliss, yet she knew her climax was approaching. She wished to stay in the throes of pleasure for far longer, but she knew he was waiting, and the mere thought of the big hunk being with her was what sent her over the edge.

Throwing her head back, her eyes rolled back, her tongue lolled out, and sparks of magic flew out of her horn, as one of the strongest climaxes she had ever endured hit her like a tsunami. Her nerves danced with delight, her legs spasming below her as she cried out.

“Yes! Yes, Spike!”

Her blissful moan reverberated in her ears, pushing her orgasm up a level as she felt it washing over her like an embrace of euphoria. She shuddered, slowly coming down from the brink, her panting slowing and the magic in her horn calming. Heaving air into her lungs, a dumb smile split across her muzzle, the heat in her depths settling down upon her cumming. Sweat ran down her form, and she laid in a small puddle of her marish juices, awash in her afterglow.

Coming to her senses, she wiped the smile off her face. Levitating a towel over to her she dried the floor up and soon tossed the now marecum soaked cloth into a nearby laundry hamper. Knowing her hindlegs and rear were drenched in her euphoric release, she shakily stood up. Wrapping the dildo in her magic, hearing it give a loud pop as it was plucked off the ground, she pulled over a smaller towel and cleaned it off. Satisfied with it, she stowed it away once more in her dresser, before making her way to her bathroom. Turning the water on, she stepped into the shower and let out a sigh.

Warm water cascaded down her body, sliding along her curves as she lightly hummed with satisfaction. The feeling in her groin had subsided, and with that she was hopeful she could keep herself together around Spike. Yet, the second she thought of him again, her carnal curiosity took hold. She had loved the feelings the dildo had just provided her, but what if it was the real deal? What if it was him pounding into her, letting out domineering grunts as he claimed her? What if he came inside her, filling her depths to the brim and bulging her belly out with the sheer size of his load?

Her legs wobbled below her as she gasped, the heat in her groin exploding back to the surface with a vengeance. Grinding her teeth, she clenched her eyes, silently cursing as she came to a daunting realization. As long as the option of hooking up with him was a possibility, she would never find herself at peace from her desires. She had just gotten herself off with intense fashion, and all it had provided was a scant few moments of clarity. This wasn’t heat, but it was something just as intense - a deep desire for a stallion or, in this particular case, a dragon.

Carefully washing herself off, she turned the shower off and stepped out. Wrapping a towel around her, she dried herself, leaving not a drop of water on her form. She glanced over at the mirror, seeing her own reflection through the hazy mist of steam the shower had created, sighing.

“Maybe you can do it. Maybe it’ll work out,” she spoke to herself, feeling her marehood wink again as her thoughts sunk into the desirable. “And it’d definitely feel amazing.”

She turned away, opening the door and closing it behind her. Now back in her bedroom, she sighed. Like it or not, she had to get an answer, better now than later. Constantly lusting over her friend would result in unclear thoughts and unneeded stress. It was time to bite the bullet or risk things getting worse or going bad down the line. She was nervous about how she’d do it, hopefully in private and somewhere secluded, but she had to bring it up. She knew he was eyeing her up, so he certainly was lusting for her body like he did her friends’, but it all came down to the emotional aspect.

Understanding the inevitable, she trotted over towards her door, and whisked it open. Rather than the empty, crystal hallway she knew greeting her, a tall, purple and green figure loomed over her. She gasped in surprise, recoiling back and looking up.

“S-sorry, didn’t mean to scare you,” Spike muttered with a deep, crimson blush in his cheeks.

Twilight blinked wildly, her nerves shooting up. “H-how long have you been waiting there?”

“Just…a few minutes, that’s all,” he replied, his voice shaky and uneven. “You were taking a while to just drop off some scrolls, so I figured I’d check on you.”

A knot formed in the alicorn’s stomach, concerned over if he had heard her masturbatory efforts. “Just f-for the past few minutes?”

“Yeah,” he answered, nodding. “I - uh - just got here.”

She heard the tinge of hesitation in his voice, leading her worries to not entirely leave her. Still, she decided to mostly trust his words, the majority of her worries calming. “Sorry for worrying you, I just needed to take a quick shower.” She hid her blush as her thoughts lingered back to the dildo and how it’d easily be surpassed by him, shuffling past him and out the door. “Alright! L-let’s go for that walk!”

He turned to face her, catching her awkward smile and poorly structured facade, leaving him wholly confused. Even then, there wasn’t any reason not to head out, so he walked right beside her as they went. Weaving through the crystal hallways of Twilight’s castle, exchanging a quick conversation with Starlight Glimmer, the two reached the front door and made their leave. Twilight swung the doors open with her arcane grasp, allowing the crisp spring air to blow against their faces as they were greeted with the ever bustling town of Ponyville. Days like this were usually quiet, serene, and calming for Twilight, but with her current state she couldn’t find the time to relax. The fresh air was refreshing, and normally would have cooled her off, but the heat in her loins was gradually climbing with every second she spent beside Spike.

Unbeknownst to her, Spike was dealing with a similar issue, struggling valiantly to control his arousal. Making their way down the steps of the castle, his eyes drifted to Twilight’s rump. His heart skipped a beat, watching as her flanks jiggled with each step she made. Every other step, he managed to catch a glimpse of her nethers. He felt the heat in his loins further as he saw her slavering lower lips for a brief moment, swallowing hard as he struggled to compose himself. Another step, another tantalizing jiggle, and another surge of need through his body. Ample, plump, and wondrously thick, her asscheeks were a set of amorous pillows he dreamed of smothering his face in. All her friends had thick rumps, even Rainbow Dash and Applejack, but hers was the absolute perfect size.

Twilight had no clue of the show she was giving the poor drake, simply focusing on keeping her tail clamped down against her. It had been mere moments outside, but she was quickly beginning to regret the decision. Beginning to walk through town, she and Spike waved to and greeted passing ponies, and the entire time she was struggling. Being around him nonstop was an amorous gauntlet in of itself, but the risk of her showcasing her lustful state to ponies in public made it all the more torturous.

“Why don’t we stop by Fluttershy’s place?” Spike suddenly asked, nervously eyeing each passing pony.

Twilight was snapped out of her focus, having been desperately funneling her thoughts on her composure. “H-huh? What made you think of doing that?”

“I’m just not - uh - feeling being around so many ponies right now is all. The walk to Fluttershy’s is usually pretty empty.”

“Oh - sure, that sounds nice,” she mumbled in response, already turning in the direction of Fluttershy’s cottage.

She did her best to hide it, but deep down she was thanking her lucky stars. The anxiety of being caught so worked up by other ponies left her knowing they’d be more isolated, and the idea of being around one of her friends helped quell her worries. Still, she had to address the issue with Spike. There was no way to avoid it any longer, but she still found herself stalling. A chat with a friend about the issue might help, and Fluttershy could be the help she needed.

Trotting towards the edge of Ponyville, with Spike firmly in tow, she felt herself finally calming down. No ponies were around them anymore, as they turned down the path to Fluttershy’s cottage. It was about a five minute walk, and all she had to do was resist her temptations before she could consult a friend for some advice. Finding herself finally pulling her mind together, she risked a glance over her shoulder and at her dear friend.

She paused her trot, seeing his eyes glued to her ass, his eyes partially glazed over. She knew that effect, it was when a dragon wanted to claim something for themselves or their horde, which meant one thing. Taking a massive risk, her heart racing, she trailed her eyes downwards towards his groin.

And her mind went wild with lust.

Hard, girthy, massive, and throbbing, Spike’s cock stood tall right before her eyes. Her marehood seized upon itself, her asshole winked enthusiastically, and her jaw dropped as she nearly drooled at the sight. Any semblance of composure left her, the carnal craving driving her mind and action. Her tail flagged itself, revealing her drooling nethers directly to him, and his dick pulsed with desire as she did. She had no control over herself, her instincts taking hold. She wanted to stall, but it was now or never.

“Y-you like it?~” she stammered, attempting to sound seductive.

Spike blinked wildly, blush forming on his muzzle as his eyes returned to normal. Recoiling, he waved his hands in front of him. “S-sorry, Twilight! I…I don’t know what came over me there! I didn’t mean to stare!”

“S-Spike.”

“I promise I didn’t mean to, I know how weird you must feel! I'm sorry! There’s just something going on with me!”

“Spike.”

“I genuinely can’t control myself sometimes! It’s something with dragon biology or whatever! Please don’t be mad!”

“Oh buck it.”

“It won’t happen again! I swear to you! Dragon’s Honor! I -“

Clap!

He finally paused, his words stuck in his throat as the sound of Twilight’s flanks clapping together reached him. Twerking her rump at him, finally caving to the desires that had built up for weeks, she let her instincts take control and took charge.

“T-Twilight?”

“It’s fine ~ I know you’ve matured a lot lately,” she cooed, continuing to shake her ass at him. “So…do you like it?~”

Spike stared in awe, wholly lost in the hypnotic motions her ass provided. He had fantasized of this exact moment, with her showing off her plump rump to him with pride, yet this was his reality. He gnawed his lip, his eyes beginning to glaze over as his draconic instincts began to take hold.

“Y-yeah, I love it…” he mumbled, licking his lips. “It looks better than I even imagined…

Hearing him outright confirm his lust towards her sent Twilight’s desire into a frenzy. “So you have been eyeing me and the girls up the last few weeks huh?~”

He gulped. “H-how could I not? You’re all flaunting those juicy asses of yours nonstop.”

Twilight shivered, hearing the tone of his voice begin to deepen. It was littered with domineering energy, his cock visibly growing even larger as he began to crave her more and more. It only encouraged her, morphing her usual quirky demeanor into the best slutty act she could put on. The claps her ass made calmed, as she slowly came to a stop. Shrouding one of her cheeks with her magic, she pulled her buns apart, spreading her holes for him.

“And do you love these?~”

Spike took a step forward, huffing hot air from his nostrils. “Twilight…what’re you getting at? Are you messing with me?”

She swayed her hips, still keeping her goods spread. “No! I’m just doing what was destined to happen. So do you love these?”

Seeing her clear honesty, he followed along. “They’re the best,” he declared, his long tongue flicking out of his mouth. “All of you are hot, but you’ve just got something special.” He composed himself and smirked, seeing her eyes focusing on his groin. Reaching down, he stroked himself slowly. “I take it you like this then, yeah? I knew I heard you scream my name earlier~”

Her confident demeanor faltered, blinking wildly as her blush exploded. “Y-you heard all that?!”

Her adorable flustered state contrasted with her lewd display perfectly, singing a song to his bestial instincts as his eyes shimmered with desire. “Not the priority right now,” he huffed, taking another step forward and looming over her. “What’s ‘destined to happen’?”

She shuddered with delight, watching as he towered over her with ease. His muscles seemed more defined, his eyes simmered with lust, and she could smell the amorous musk he provided as he stood inches from her. Letting go of her asscheeks, her flanks clapped back together, as she whirled around and looked up at him.

“You and me, in those bushes over there, right now.” She shrouded his arm in her magic, tugging him along with her. “We both need to just do it.”

Spike didn’t resist her tug, stumbling behind her as his arm was yanked forward. “But what is it -“

With a final, firm tug, he slipped into the bushes. Glancing up, his eyes went wide as dinner plates, and the doubts or worries in his mind faded away by what was before him. Stooping down slightly, with her ass raised in the air, was Twilight. She flagged her tail, showed off her goods, and looked back at him with a sultry gaze.

“We can’t stop lusting for each other, can we? You can’t stop eyeing me up, I can’t get the thought of you out of my head.” She hesitated, a tinge of her usual logic creeping in through her desire, but she continued on. “So, we were destined for this. Destined to properly fuck.”

Spike’s heart thumped in his chest, eyeing up Twilight’s wondrously presented goods. Her pussy winked wantonly, beads of her essence drooling out of it and coating her thighs. Right above it, the velvety ring of her succulent ponut rested, glistening slightly with sweat. His balls ached, his chest twisted into a knot, and he felt literal fire boiling in his gut as his instincts urged him to claim her.

“You sure nopony will catch us?” he asked, anxiously looking around.

Twilight swayed her hips, groaning to herself. “We’re off to the side of a rarely used path. C’mon, Spike, you want me and I need you~”

His inhibitions were sundered with her desperate plea, as he subconsciously took another step towards her. He could barely think straight, his mind awash with bestial desire and lust, but that only elevated his enthusiasm. For years he had to hold back his draconic instincts and behaviors, but when it came to this one, Twilight was offering him a golden ticket. Coming up behind her, looking in awe at her rump, he extended his claws and grabbed her flanks.

Her fat asscheeks were like marshmallows in his talons, encouraging him to caress them gingerly. Her flanks weren’t incredibly big, but certainly above average. Ponies in general had hefty plots, and Twilight’s was the perfect size. He continued to feel up her rump, gulping with both nerves and excitement as he caressed the region her cutie mark laid in. Gripping down on her plump flesh, he spread her cheeks and eyed her nethers. Her pussy looked tantalizing, angrily winking as it was desperate to be filled, but as his eyes drifted up, he craved for something else she had to offer.

He let go of her ass, raising a claw and firmly smacking it. She let out a pleasurable gasp as her flank jiggled from the strike, a surge of her lust spurting from her cunt as she did. He didn’t know why he felt so compelled to smack her rump, possibly due to his domineering nature as a dragon taking hold, but regardless she seemed to enjoy it. Slapping her other cheek, watching it ripple beautifully, he huffed steaming air from his nostrils.

He shifted himself, slapping his cock right between her asscheeks, forcing a throaty moan to escape Twilight’s throat. Inspired by his forwardness, and the warm log of flesh resting between her flanks, she pivoted her hips as she slid her holes along his shaft. Grinding against him, shuddering with every pulse of his shaft, her eyes fluttered. She couldn’t believe she was here, doing this with him, but it felt so right and it was just getting started.

“You ready?~” he snarled.

The ferocity in his voice made Twilight’s hair stand on end, her excitement knowing no bounds. “Y-yeah, c’mon. Fuck me, you stud - wha!”

Her eyes went wide, feeling him grip her tail right above her dock. A warm, teasing feeling prodded against her asshole, sending a burning inferno of lust to surge through her very being. She had expected him to rail her marehood, and never even considered him going for her backdoor!

Gnawing her lip, her eyes rolling back partially as she felt his tip tease her hole, she glanced back at him. “Y-you’re going there?~”

His eyes shimmered for a moment, becoming clearer as his expression warped to one of concern. “Is…is that okay?”

She shivered, feeling him throbbing against her tailhole. She wasn’t inexperienced with anal, she was rather fond of it in actuality, it was just the idea of him going for it in their first rut that caught her off guard. Smiling to herself, appreciating his clear concern, she winked at him.

“Ruin my ass, Spike~”

And that was all he needed to do just that.

With a deep, bestial growl, he pivoted his hips forward, plunging his cock into her tight depths. His balls slapped against her pussy, teasing her clit as his knot bumped against the rim of her ponut. Twilight threw her head back and let out a deep, guttural moan, her nerves exploding with pleasure as the intrusion met her. She could feel every beat of his heart as his dick throbbed within her, pushing her body to new limits with ease. She had been right, the real deal was a magnitude more intense and pleasurable than she could have possibly imagined.

Spike pleasurably winced, gripping onto her tail tightly as he felt her depths clench down onto his member like a vice. Her walls were an angel’s caress, giving every last inch of his dick pleasure unlike anything he had ever felt before. He wasn’t too inexperienced with the idea of sex, having had a more than eventful rut with Smolder back when he turned 18, but this was his first time with a pony - and he was quick to realize just how amazing they felt. Her ass bounced when his groin slapped into it, he felt her clit wink against his balls, and her asshole massaged his cock better than he could’ve ever dreamed.

They held their position for what felt like eternity, doing their best to drink in the situation. The spike of pleasure accosting them both would’ve been a shock enough, but the fact that their relationship had taken such a drastic shift with this mere action held all the more weight. Slowly, Spike drifted his free claw down the curve of her ass and towards her hip. Carefully grabbing onto her waist, he pulled her tail up further, bracing for what he was destined to do next. Twilight glanced over her shoulder, meeting his eyes with her own. Both of them held unkempt lust within them, their eyes shimmering with desire, and, as if a silent agreement was made, he set to claim her.

He pulled back, a trial of her essence connecting his balls to her pussy. Leaving only the tip within her, he grit his teeth and slammed back into her. A loud, wet smack rang out, as their bodies forcefully met again, followed by yet another blissful moan escaping Twilight’s lips. This time, he didn’t stop, pulling back and repeating the motion - again, and again, and again.

Twilight’s mind reeled, the sheer volume of pleasure accosting her from a realm unbeknownst to her. Each time he thrusted into her, her body lunged forward, her depths convulsed around him, and she screamed out with sheer ecstasy. She was worried about the rare chance of a pony traveling down this trail, but with how good she felt, she couldn't care less if somepony else heard.

His grunts mixed with her moans and the slaps of their lovemaking, urging her to match his efforts in tandem. Bracing herself, she began routinely throwing her ass back in time with his thrusts. His cock reached deeper, her moans grew louder, and the frequency in which he filled her only rose. Her ass jiggled with each slam, her clit was teased every time his balls smacked against it, and his grip on her strengthened as he too became lost to his lust.

On and on they went, minutes feeling like hours, with neither letting up. The smell of lavender filled the air, soon mixing with the scent of smoke - Spike huffing literal smoke out of his nostrils as his efforts grew. Any reservations they may have had faded away, now indulging themselves in the moment. Right then, they weren’t lifelong friends. Right then, they were mates.

Slowly yet surely, after what felt like a small eternity, the inklings of a climax began to brew in each of their depths. Her body began to quiver, and his legs began to buckle, yet they weren’t done just yet. Their pace increased once more, both of them preparing for their blissful peak of their efforts. His thrusts grew frenzied, his nuts pushing Twilight closer and closer to the brink, as he heaved air into her lungs and managed to get a grasp on reality.

She looked over her shoulder at him, tongue lolling out as she was unable to contain the sea of moans escaping her lips. “C-c‘mon, Spike! Nnngh! Pump every last drop into me! Haaa! Mmmph! Breed my ass!”

He merely snarled in response, gritting his teeth as he fucked her asshole with reckless abandon. His breathing picked up, sweat beading down his body as he steadied himself for his final act. Pulling back nearly entirely, holding barely his tip within her ponut, he snarled and plunged himself into her with everything he had. With a loud pop, his knot forced its way into her asshole, locking his member within her depths. Throwing his head back, he let out a deep, menacing roar, green fire spewing from his mouth and up into the sky.

Twilight’s entire body seized, unprepared for the sheer intensity of the pleasure she was enduring. His knot slipped into her depths causing her eyes to flutter, and, feeling the warmth of his fire spewing in the air above her, she knew what was to come next. Her climax hit her with the force of a dying star, as the first, massive ropes of his cum filled her depths. Her cunt gushed with her arousal, marish juices spewing out of her and coating the ground, his straining nuts, and his thighs.

Each eruption of cum filling her was a measure greater than anything any stallion could ever offer. Within the first few moments, her belly bulged subtly, the sheer volume of his essence flooding her depths. Her eyes rolled back, her entire body shivered intensely, and her tongue lolled out as she gave a noiseless scream. She teetered on the brink of pure nirvana, the world around her fading away as she was wholly encapsulated in the euphoric moment of their mutual release. Nothing, and she meant nothing, could compare to the pleasure coursing through her every last nerve, making her nearly burst with unfiltered, unrefined bliss.

Eventually, Spike managed to pull back, another pop ringing out as his knot was forcefully pulled from her depths. Her asshole gaped open, a waterfall of cum gushing out of it, as the final vestiges of his seed spurted from his member and coated her ass and back. She wobbled in place, barely able to stand, magic fizzling in her horn as she grasped onto her reason and tried to remain standing.

Spike heaved air into his lungs before her, wiping sweat off his brow as he came down from his orgasm. “Haaa ~ T-that was…insane.”

“Y-yesh…sho…sho good…” she mumbled, still riding out her own orgasm as another spurt of cum came from her ass.

Spike scrunched his muzzle, his concern tearing through the euphoric afterglow. “Uh…Twi? You okay?”

Twilight blinked slowly, panting heavily as she came down from her high. “A-ahem…yeah…I’m good,” she groaned, smiling back at him. “You…are incredible.”

“I can't believe I…we just did that!” Spike blurted out, his eyes returning to their normal look as his lust was temporarily quenched.

Twilight giggled to herself. “It was bound to happen and, look, it was great!”

Spike met her gaze, her cheery demeanor calming him. “Yeah…it was.” He paused, raising a brow. “Since when could you talk dirty? Let alone pose and act so…so slutty!”

“Clopimarn’s Guide to All Things Dirty, Devious, and Degenerate,” she nonchalantly replied, chuckling. “Volumes one through five!”

Spike threw her an unamused look. “Books, right. It’s always a book.”

“What? I like studying, I like books, and I definitely like doing the deed with you ~ So, it was a perfect series to look over!” she intoned, furrowing her brow.

“Alright, alright, I get it! You like books, and, I know now, you also like dragon dick.”

“Your dragon dick in specific, Spike.”

He crossed his arms, looking over the messy state she was now in. “Well, what do we do now? You’re covered in cum and -“

Before he knew it, magic swirled around Twilight, the cum and remnants of their sexual embrace whirling and disappearing before his very eyes. Before long, she looked like her normal self, not a smidge of cum on her - even her asshole wasn’t partially gaped anymore.

“W-what? How did you?” he stammered, watching as he soon was shrouded and cleaned up by magic as well.

“Clopimarn’s Rut and Run spell!” she explained. “Located in volume one, chapter 87, its purpose is to help any creatures that need to rut get it out of their system as fast as possible! It was first used during a royal dinner when…”

“Alright! It’s from the books you read! Forget I asked!”

She snickered to herself, seeing the dopey yet adorable smile on his face. “Well ~ Now that that’s done and over with, why don’t we finish heading over to Fluttershy’s?”

“That’s it? We just did all that and now we’re just acting normal?” he asked, gobsmacked. “Twilight, you of all ponies should be the one freaking out right now!”

She shrugged, bumping his hip with her own as she trotted back towards the path. “I am feeling more relaxed than I ever have in years. Yeah, we’re going to talk about it, but we can once we’re at Fluttershy’s!”

He followed behind her, rubbing the back of his head. “Uh…we’re going there to talk about it? Isn’t that - yknow, a bit weird?”

“Y’know…” she started, eyeing him up and down as they began to walk down the path again. “Now that you’re older…” She eyed Fluttershy’s cottage in the distance, turning back to him. “Ever wondered what pony pussy feels like?”

“I…l…” he stammered, a blush forming on his face.

She giggled. “I mean, you tried out pony ponut, but not pony pussy.”

“Y-yeah, I have…obviously. Why?” he sighed.

She glanced off into the distance once more, making out the faint visage of Fluttershy as she tended to some animals. They’d be there any minute now, and even though she had just endured a mind-bending climax, an idea in her mind began to grow alongside a returning heat in her groin.

“Oh, just asking for a friend~”
