"Starlight Glimmer is baffled by the layout of Twilight's palace! In search of a path to the observatory, the mare unknowingly opens the door to sensual mischief, when she happens upon a certain dragon in a very compromising position..."

Starlight might be improving her sense of friendship, but that doesn't mean she can't give into her conniving ways when the chance presents itself! In this case though, she might have bitten off a bit more than she can chew...

Inspired by the first episode of Season 6, this story features an aged-up and slightly more mature Spike rather than his baby dragon self from the show.

Features: Straight inter-species sex, knots, mild blackmail, some light voyeurism, and pent-up draconic urges run amok.

Definitely Not a Broom Closet.

The Castle of Friendship. A crystalline structure wrought from the magic of seven unique companions overcoming all odds, the desolated Ponyville library reborn into a shimmering testament to the wonders of their camaraderie...and for the pink-furred unicorn whose cries of anguish echoed through its halls, a labyrinthine nightmare!

"Argh! Why does every door in this forsaken place look exactly the same?!" Starlight Glimmer snarled in frustration, her magic slamming the door to yet another supply closet, thankful that a pack of ferocious brooms and dustpans decided to withhold a frontal assault this time. Starlight gathered herself with an indignant huff, rolling up the sleeves of her snug light-purple turtleneck sweater. A short length camel skirt matched the full-figured mare's top, nothing to hinder Starlight's irritated march for the palace observatory.

"If Twilight Sparkle had any sense, she'd put labels on all these doors by now! How does anypony in Ponyville make use of the new observatory when they'd have to bring a map, compass, and a week's provisions to find it?" Questioning herself for an answer nopony gave, Starlight's black boots stomped down the winding corridors of identical doorways, irate from nearly a half-hour of fruitless searching.

"Think Starlight, think a little," The unicorn pondered, slowing her trot with arms crossed at her chest, Starlight's blue eyes studying the seemingly-endless rows of tinted-green doorways stretching out at both sides like glittering pines. "Broom closet, kitchen, study, broom closet..." She counted the previous rooms on her fingers to orient herself, a revelatory smile crossing her lips.

"Okay, I've got it! Start at the left, third door from this one, and if Twilight was right, the stairwell should be...Here!" The mare declared, her magic gently pressing open the final door she dared attempt, or else she'd give Twilight Sparkle a "lesson" of her own in plotting directions when the mentoring alicorn returned, one for the whole castle to hear.

Darkness greeted her, not the best sign, but the openness of the chamber drew the mare inside, hoping for a detour. The doorway gingerly clicked shut behind her tail, Starlight's blue magic sparking alight to illuminate the gloomy passageway, long-sought relief dawning across her muzzle at the sight of stairs leading upwards.

"Finally! Knew I'd find the way eventual...?" Starlight began, the mage silenced by a truly beastly, agitated grunt resounding from above, sending her fur on end in fright!

"Grrrr...!" The strange sound repeated, freezing the unicorn in place, Starlight left wondering if some rabid beast from the Everfree crept inside, or a forgotten "experiment" from her mentor's misadventures in magic and science lurked the castle's darkest corners.

"Wait a second..." Starlight thought, the unicorn's ears perking up to focus on the grunts, fear slowly evaporating from her pattering heart. "It's more like something, somepony is straining themselves? That voice..." she considered, allowing shimmering blue arcana to envelop her form, telekinesis ferrying Starlight silently to the apex of the isolated stairwell. Before her stood another doorway of dark-green glass and wood, the dim light from within casting a shadowy silhouette flickering from the other side.

"So, Starlight, what'll it be? Run down in horror with your tail tucked between your legs, never to return? Or, intrepid as you are to nearly shatter space-time on a whim, dare pry further?" Starlight's grin returned at the self-speculation, certain she'd guessed the noisy occupant's identity. A tantalizing offer of mischief on the other side proved too much for her to resist, and with a quiet push of her fingers, Starlight peered inside. Her observation proved spot-on.

"M-Mmmphh!" the scaled figure greeted at her entrance, Spike so enthralled by the photograph clenched in his claw that Starlight's peek went unnoticed. The chamber appeared to serve as a spare guest room, furnished like the rest of the castle but seeing little use, hardly surprising given the expansive nature of the place. Starlight nearly rose her voice to ask the young dragon what ailed him, or why he'd shut himself away from everypony, but the truth sprang on her so abruptly, she nearly gasped!

Starlight recalled seeing pictures of Spike taken just several years ago, when he stood nearly half her height and seemed more like Twilight's "pet" than assistant, but she'd never known that Spike herself. The drake experienced a rapid shift shortly after becoming a hero of the Crystal Empire in both maturity and stature, entering the adolescent stage of dragon life.

Though somewhat lanky, Spike matched heights with most stallions in Ponyville, sporting toned muscle in his appendages, and hardly needed help carrying nearly a wagon's worth of books around the castle library at any time. Spike's snout and tail extended, his scales grew more pronounced, and that handy flame breath proved all the more disastrous if an unchecked sneeze escaped him. Yet for all these changes, the one capturing Starlight's gaze stirred a very different drumming in her chest, born from lust rather than fear.

"Oh, R-Rarity..." Spike sighed from his perch on the bed, laying on his back with the picture filling his gaze, idly licking his lips in yearning. Gently, his free hand worked across a hardening draconic member, risen from a small slit once concealed beneath scales. Red as desire itself, Spike's budding erection swelled under this inexpert touch, his base showcasing the bulbous start of a growing knot. Starlight gleaned from certain "academic journals" that dragons possessed no outward testicles, but the sheerly bestial nature of Spike's needy genitals sparked an excitement in the mare far divorced from any guise of purely scholarly intent.

"Since when did you become such a gawking peeping Tom, Starlight?" the mare mentally chastised herself, until a deep groan from the dragon drew her eyes back across the pink length throbbing to life between his fingers, the sight spreading sodden heat underneath the unicorn's skirt. "Probably since you found out Twilight's draconic assistant doubled as Ponyville's most exotic stud! Besides, he owes me for that Crystal Empire run-around nonsense, it'd be fine payback to spoil his little interlude. Or even..."

"R-Rarity, you're so wonderful! Mmphh! I-I want you..." Spike grunted, tension riddling his voice from the strain of fumbling with the blessing between his legs, spurring Starlight's wicked imagination into a plan for reparations. Magic cloaked the mare's outline once more, the mirror-like sheen of an illusionary enchantment blanketing the mage's fur.

"H-huh? Who's out there?" Spike stammered, the dragon's keen ears catching the tell-tale shimmer of magic, his eyes wide in fear of discovery. That fear became sheer terror as the door swung open to dramatic effect, the prize of his fantasies wreathed in a brief otherwordly glow. The ivory unicorn stood at the door, Rarity's sensual, womanly figure teasing an eager twitch from his bare length as she stepped inside, her azure eyes darting about the hideaway. "Rarity?!"

"Daaahling, my dear Spikey-Wikey, what could you possibly be doing up here, all by yourself?" The ravishing fashionista questioned, strutting into the dragon's private chamber. Spike panicked at once, throwing himself into a fruitless effort to conceal his arousal under the sheets, lest the dragon's teenage crush discover his fantasies. "I've been looking for you all day, and here I find you, moaning and roaring in the dark! Is something wrong dearie, are you ill with an obscure reptilian flu?"

"N-No! I'm fine Rarity, really, heh! Uh, never felt better! I was, ah, just up here, stretching out my, uhm, tail, is all!" The lanky dragon spat out an excuse, writhing underneath his blankets at the ivory mare's approach, oblivious to the twitching lump at his groin.

"Something is definitely the matter with you, I just know it! Let me see...Come now, Spike! You're not hiding anything from me, are you?" the unicorn huffed, leaning forward to press her bare palm at Spike's forehead. "My goodness, Spike, you're burning up!" she gasped in faux concern, sure to leave the bosom straining underneath her uncharacteristically-plain blue top dangling in front of his snout.

"I-I'm always hot like that, Rarity. I'm a dragon, that's normal!" Spike protested through gritted fangs, claws latched onto the covers to keep them down, his anxious emerald eyes remaining fixated on the mare's heaving chest, so tantalizingly close.

"Oh, you're right dear, I suppose it's fine," Rarity conceded with an odd snicker, stepping back from the dragon, Spike sighing with relief at her retreat; until she stood at the foot of the bed, his damning secret hovering in her open palm. Spike's expression froze, doom upon him.

"Is it also normal for young dragons to snap racy photos of their dearest friends in swimwear?"

"I, uh, I can explain!" Spike stammered, practically bolted in place, his dark shame discovered by his biggest crush. Defeated, the dragon looked away, disgusted with himself. "Actually, no, I can't. I'm so sorry, Rarity."

"I'd be willing to bet this isn't the only one either. My, you've certainly got a keen eye for positioning! I'm surprised she, ur, I didn't see you take these," Rarity commented, quickly discarding the flub and near-ready to spring her trap. "I can't imagine what would happen If I let Twilight know about this, especially if you've snapped a few of everypony else? Fluttershy, perhaps? Or even, dare I say, Twilight's bodacious new student, Starlight?"

"G-Go ahead, tell Twilight! What I did was totally wrong, I got greedy and couldn't stop myself!" Spike admitted, letting the sheets fall against him in a bow of acceptance, hardly aware of the needy length still risen between his legs. "It's just been so hard though, with this new body. I-I have all these thoughts, these urges to-"

"To fuck?" Rarity finished for him, her delicate hand cupping Spike's chin and lifting his gaze back up to meet her own. "To stake your claim in a ripe female, and spread your seed?"

"...Y-yes?" Spike bleated in confusion, the poor young dragon stuck on an emotional roller coaster ride. Rarity's smirk widened to a malicious degree, the energy enveloping her form shattering with a jolt of blue color from her horn, the illusion of Spike's crush vanishing in a tattered veil of fragmented magic. In Rarity's place stood Starlight, her deception revealed.

"Gotcha!"

"Huh, what? S-Starlight?!" Spike grunted in alarm, instinctively trying to swipe the picture back from her once the ruse fell, but the mare's magic proved too quick for his clumsy fingers. "Give that back, now!"

"Oh, I will! Don't worry, I'm not here to out you, "Spikey-Wikey," Hah!" Starlight reassured in a somewhat-convincing impression of Rarity's ladylike tone, the photograph teleporting out of Spike's reach. "Consider this just desserts for that fiasco in the Crystal Empire!"

"Ugh, fine! You've had your fun embarrassing me, we're even now! Give it back!" Spike snarled indignantly, the dilemma doing nothing to dampen that which already bobbed readily between his legs, which stole Starlight's attention.

"Certainly, on one condition: I give you this little snapshot and keep quiet, but you'll owe me something in return! Deeeeal?" Starlight offered with an innocent smile, her eyes on the prize.

"Deal! Just give it back!" Spike roared in reply loudly enough to echo downstairs, impulsively accepting the conniving mage's agenda without second thought.

"Done." The nefarious mare whispered, snapping her fingers with a spark of magic. The treasured photograph appeared in Spike's open claw, but not alone; accompanying it were a pair of lacy purple panties, stained with the tell-tale scent of a mare in need.

"What the heck are thes-?"

Spike blubbered in confusion, presenting Starlight the opening she craved; before he recovered, the mare's intrusive muzzle met that of the bewildered dragon, seizing the moment. Though Spike surely overpowered her physically, Starlight's surprise smooch forced him backwards onto the bed, the unicorn mounting herself on top of the shocked dragon. Breaking the sloppy kiss, she spoke frankly.

"From now on, you're not allowed to waste that gorgeous hard-on anymore when I'm around; Is that crystal-clear, Spike?"

Struck of all reason to waver in the wake of her demands, the sex-starved dragon managed a meek nod in reply. His rigid shaft pressed at the base of Starlight's flicking tail, a single twitch of his tip pressing underneath her skirt telling the mare all she needed to know.

"Mmm, that's what I like to see, a willing dragon in his prime! Truthfully, I've been curious about this for awhile..." Starlight admitted with a glance southward at the handsome stud she straddled, the mare's magic flaring up once again, enveloping Spike's rigid length in caressing blue light. "I've heard all sorts of stories about your kind, but since you're not entirely used to this wonderful body yet, I'll help you explore it myself!"

"Starlight, d-do you think we r-really should be doing this?" Spike choked out halfheartedly, only just regaining some measure of composure, though the unicorn's massaging magic tending to his maleness in ways that put his hands to shame threatened to steal even that away. "What if Twilight finds out? She'll blow a gasket!"

"Hmmph, her loss then, because she's been missing out on blowing a lot of things lately," Starlight quipped back with a cackle, wooing the teenage dragon, his reservations only a distraction from the womanly treasure upon his lap, a fantasy come to life. "Don't you want to touch the real thing, a real mare? Twilight'll keep you sheltered from that, but I can give it to you whenever you want. Unless you'd prefer jerkin' off alone up here..."

"You w-will?!" The dragon gulped, his claws unwittingly fawning at Starlight's plush sides, digging into the mare's blouse, coveting what lay underneath. The touch spread a heat, a rush of alluring hunger through Spike's scaly chest, and a toothy grin unfolded upon his maw. "Whenever I want?"

Certain that the dragon faltered under her seductive spell, the mare leaned in for the kill, missing the strong inflection of desire in Spike's final word. A grave error on her part. "If that draconic dick of yours lives up to its "stature", "Spikey-Wikey," you'll never be alone up here again."

Spike required no further invitation, though Starlight soon found it was her turn for a surprise, the enthralled drake's claws extending just far enough to rip into her blouse, tearing the bothersome blue fabric from her body while leaving only a slight imprint of their passing on her pink fur.

"Spike, stop that! You're ruining my-Ahh!" Starlight objected, only for Spike to silence her with a kiss of his own, one born from long-starved lusts for a mare in his grasp. Putting his new strength to use, Spike tore Starlight's blouse into ravaged tatters, leaving her ample bra-covered breasts within reach. Growling harshly as a beast might, the dragon's lengthy, thick tongue forced its way into the mare's muzzle, practically encircling her own and silencing any pleas for restraint.

"Mmmphhh!" The cocky sorceress managed in protested, Spike's forked tongue lashing at her own, the damp heat of his mouth meeting hers only paling to the sort brewing between their legs. Starlight tried to master her magic in a vain attempt to spare any of her clothing from the dragon's perverse wrath, but Spike's greed could not be denied!

"Grrr, MINE! MY mate now! Rargh!" He snarled into her mouth, the dragon's claws slashing down the chest of the prankster-turned-prey, ribbons of Starlight's purple bra joining tatters of destroyed blouse on the bed. Free and bare, the unicorn's plentiful tits swayed before his craven eyes, a fire of desire simmering in Spike's hungry gaze, as if enraptured by their swell.

"Damn it, Spike! You've ruined my clothes! Oh, you're gonna pay for that twerp, just you wai-Oh!" Starlight admonished, or at least tried to, but Spike's break of their kiss only meant that his mouth sought the taste of her offered mounds instead. The young dragon's snake-like tongue flicked across her left nipple, suckling deeply of the enchantress, his lewd slurps concealing the cartoonish "riiiiip" of Starlight's skirt disintegrating at the swipe of his free hand, leaving nothing between their bodies.

Caught in Spike's predatory pounce, Starlight squirmed at the mercy of the growing drake's daring tongue, the hunger of a sex-starved adolescent dragon knowing no restraints. She yelped helplessly, shivering at his forked tongue playing along her hardened pink nipple, a draconic talent that her information-rich textbooks failed to mention, or warn cross-species-temping scholars about.

"Oh fuck, Spike, you're a real monster! I-I didn't think I'd, didn't know you'd be so, so much of a stud, so wanting-!" The unicorn struggled to form words, Spike's attentions coaxing out only moans, his mouth slurping deeply of her weighty mounds, while a scaly hand cupped Starlight's remaining breast. Straddled in what might pass for heaven, Starlight relaxed into the drake's grasp, only then remembering a rigid pole prodding up against her mound, bare and slick with pre.

"Rrrrgghhh, ready now, ready to MATE! Spike wants, Spike wants to fuck, to FUCK Starlight! Starlight belongs to ME, she's MINE!" He snarled in bestial need, the dragon's first touch of a mare's body so intoxicating that the monster within took over, as different kind of "monster" prodded at Starlight's winking, ready cunt. Starlight shivered as the rigid flesh flicked across her winking slit, a moment of doubt flashing across her red-flushed face, recalling studies warning that nothing matched the ferocity of a dragon possessed by desire of any kind.

"A-Ahh, screw it, screw me Spike! I don't give a damn if I can walk straight after this, just put it-Oh, fuck YES!" Starlight pleads, tossing aside her inhibitions with a single fall of her hips, spearing herself deep on Spike's tapered dick. An enticed growl rumbled from the young dragon, praising Starlight's initiative in stealing his virginity all for herself, the evil gleam in his fiery emerald eyes aiming to pay her schemes back in kind, tenfold.

"Rrrraaagghhh!" Spike's claws latched onto Starlight's plush hips firmly, hard enough to press into her pink fur and leave lasting impressions across her cutie mark. famished for sex, Spike wasted little time, spreading apart the devious unicorn's warm marehood with several hard inches of ridged, monstrous dick, the heat of his maleness forcing the mare's eyes wide open.

"O-ohh, so deep Spike, ah! Stupid stuck-up R-Rarity, stupid b-bookworm Twilight, they're both missing out on this, fuck! Their fuckin' loss, cause I'm gonna be your secret squeeze from now on! Oh, deeper!" Starlight proclaimed with a craven sort of pride, sweat gathered on her brow from the heat between their grinding bodies, Spike's probing draconic dick utterly filling her slick pussy. Starlight leaned forward, hands roaming the powerful scales across Spike's chest, each flexing against her palms to drive himself further into the first maiden to submit itself to his conquering dragonhood.

"Spike wants a taste, to taste HIS mate!" The panting teenager ordered, his long tongue darting across Starlight's bouncing breasts, the prehensile organ tugging at her sensitive nipples without mercy or pause. Spike's throbbing dick blurred from the savage frequency of his thrusts up into the unicorn, relishing the tender pussy yielding to his draconic rod so readily, while the "spearhead" shaped member pounded roughly at Starlight's depths.

"Taste all you want, take all you want, yeah! Fuck, Spike, you're giving me a better lesson on dragons than any dorky books Twilight has, ugh! F-Fuck, I can't believe, I think I'm already about to c-cum-" Starlight rambled in drunken bliss, but Spike felt the tension rising in her squeezing walls, breeding instinct telling the young dragon that the swollen base of his cock might find its proper place inside his mate.

Already, Spike put the previous stallions Starlight wooed to shame, even the hung studs Party Favor and Double Diamond, the drake pounding into her cunt certain to leave the unicorn one of hopefully many mares addicted to his cock. Yet, as Starlight came on his dick, Spike drove himself even deeper still, the bulbous swell at the base of his shaft yearning to feel her climax welcome it inside.

"O-Ohh, fuck! D-Did you just get even bigger just now?! F-Fuck, it's that, it's that fuckin' knot, yes!" Starlight shuddered, the unicorn enraptured by the engorged, pulsing draconic member staking its claim of her body, spreading her folds wide before slipping snug into the unicorn's dripping-wet cunt. Starlight slumped forwards into Spike's chest, her tongue roving his scales in tribute to the once-virginal dragon, his swelling knob accompanying the bliss of the mare's recent release with a gentle, satisfying sense of fullness.

"Spike WANT more, raaghh, Spike not done mating, not done making Starlight all MINE! Spike will not stop, not until Starlight takes his seed!" The drake panted into his knotted mate's ear, though he showed some restraint for once, a moment of recollection spent touching, kissing, and grinding between the pair. Spike took in the mare's scent, his tongue flicked playfully across her soft neck, teasing Starlight into a sense of pleasured ease; at that moment, he struck, pushing her up and pulling backwards, his knot popping free from her damn cunt, before quickly hammering itself back deep within.

Whatever heights Starlight felt with her former lovers became mere shadows of the vibrations rocking her tender marehood, the elated unicorn's muzzle agape in awe at Spike's knot claiming her again, and again, with no end in sight. "G-gosh, Spike, ugh! Yes, yes, yes! Mate me, breed me, fuck me deep! D-Do whatever you want to me, inside me!" She cried aloud without shame, submitting entirely to the jackhammering dragon dick nudged hard against her soft cervix, jolts of white-hot precum coating the way for Spike's (and her second) imminent peak.

"Arrghh! Spike OWNS Starlight, my mate to SEED, to FUCK, to BREED! R-RAAWRRR, take it, take my SEED!" The young dragon thundered in a fierce storm of thrusts, pounding Starlight thoughtlessly as instinct took over, her delicious mounds bouncing and a star-struck mew of bliss upon her face his final sight before nature took its course. Spike's knot trembled a final time, swelling fully lock the pony and dragon together, forming the perfect dam to keep rich, steamy jets of potent draconic spunk from escaping Starlight's willing womb.

"N-Never, never going back to ssstalions, Ooohhh..." The magus sighed in rapture, the sticky heat spread through her insides soothing her sore marehood with its gooey splendor, Spike's lack of obvious testicles doing nothing to stall the geysers of sticky sperm from charting its first mate. Starlight struggled to remember if any stallion lover flooded her so completely, or left her so satisfied from mane to tail, but found no equal to the young dragon, who held his mate snug to his chest all the while.

"S-Starlight...? I-I'm so sorry, I didn't mean too-I don't know what came over me!" Spike choked out, the primal urges fulfilled and giving way to confused teenage logic, the once-proud dragon shuffling in shock at the sinful aftermath of his own first time. "Oh, Celestia, I f-finished inside you?! W-What if you get p-pregnant by me?! Twi, Twilight would kill us both!"

"...Spike, you know dragons can't knock ponies up, right? I just said that stuff cause it was hot," Starlight replied, deadpan in tone. "At least, I'm 99% sure it doesn't work that way. Sheesh, Twilight really has kept you sheltered, hasn't she? You poor, poor thing!"

"H-Hey, shut up! I'm new to this," Spike protested, initially exasperated, before returning Starlight's snarky comeback with a grin, showcasing his glinting teeth. "You're the one with the dragon cock inside of you, so you don't have room to talk! Besides, Star, what did I hear you say before? You know, that whole doing anything I want; Whenever I want part?"

"Ah, now you're getting the hang of it! I'll make a maiden-stealing dragon out of you yet," Starlight chimed, leaning her head onto the dragon's shoulder, the intimacy of feeling his pulse into her in time with the beating of his heart intimate beyond compare. "I'm a mare of my word! Part of that whole "friendship reform program" thing after all, but I didn't quite expect inspiration to write a field-guide on dragon lovemaking today. With so many mares missing out on studs like you, well..."

"Hmm, you know what? I bet that charitable mission would make for a great step on the road to reform; since you're gonna get a whole lot of "experience" in that field from now on, my mate." Spike agreed, the hint of gathering dominance in his inflection subtle, but growing, sending a shiver of excitement through Starlight's backside.

"Then it's settled! Course, I'll have to write it under a pseudonym...Strobe Stutter, maybe? Think that's subtle enough. Oh, and I've got a question for you, stud."

"Trixie can come too."

"W-What did you say?" Starlight blinked, uncertain what she'd just heard.

"Oh, nothing. What's up? We've, ah, got a few more minutes before this goes down, and then we'll have to clean up..."

"Okay, just where the hell is the observatory?"

"The opposite door in the hall from here," Spike answered, stroking the mare's backside with fawning fingers. "Why?"

Starlight smiled, her muzzle meeting Spike's in a gentle, lingering kiss, a sharp and intimate contrast to the sloppy, lust-drunk dance of their rutting. She broke the kiss slowly, her thoughts alight with plans for the night alone with her new draconic lover.

"What would you say to a little "star-gazing" party with me tonight, Spike?"

"I'd say we won't be looking at the stars very much."

"Got a problem with that?"

"Not one bit."

Author's Note

This was a very fun idea, one that I initially intended to be a quickie clopfic. Obviously, now that S6 is long over and S7 on the way, the "quickie" part didn't quite happen. Still, very pleased with how this turned out, and hopefully you, dear reader, enjoyed it!

I had an idea to get Trixie involved in these shenanigans sometime, since she'd be a really fun character to write, but that'll be something on the ever-growing list of ideas to make reality on the page. I tried some different uses of italics, bold text, and the like with this story, as I figured that'd be a good way to imply inflection or urgency. Hopefully they're more engaging than distracting!
