It was time for the main course.

With renewed vigour, she slithered up the Starlight’s vaginal canal, into truly untouched territory, parting the depths of her walls of the first time ever, wiggling like an earthworm through moist earth as she sought a pathway to the mare’s most sacred depth.

“Ahn! Ahhh! Oh… oh my G-goddess… f-fuck!” Starlight’s body was coiling and writhing on the snakelike tentacle of a tongue, overwrought with pleasure and sensation. Mini-orgasmic shudders spawned from her gut with each exploratory wiggle of her queen’s oral lasher, often sending her into a powerful wink that splattered the slate floor with hot splashes of mare-juice.

Deeper, deeper. Parting these incredibly tight, clenching walls which would need to be well exercised before even attempting to take Chrysalis’s size… or perhaps not… a little squealing could be fun too. A queen did like to be feared and respected, after all.

In any case, Chrysalis finally reached her target - a tight orifice of ringlike flesh, buried at the very depths of Starlight’s delicate horse-pussy. Her cervix. The gateway to her uterus. Her womb.

And what would soon be their egg-creche.

But it was not without its defenses - a tight constriction, a mucosal layer, a darting-shivering movement. Starlight’s biology somehow new, at an instinctive level, not to permit the changeling invader into itself… to expose that most precious inner-sanctum to corruption and defilement. To risk the genetic material of thousands of gamete-cells in Starlight’s ovaries. Only a stallion was permitted to enter here.

But changeling biology was superior, adaptive, evolved… and Chrysalis was a master defiler.

The tight constriction had already been loosened by the powerful neuroleptic brew that was boiling the mare’s forebrain in pleasure-chemicals. The mucosal layer was easily dissolved by shape-shifting a part of her tongue tip to emit an analogue of a stallion’s pre-ejaculate. And the darting movements were slow compared to the hummingbird-like agility of Chrysalis’s insectoid tongue-muscles.

On her very first strike, she speared the delicate opening, first slithering in the barest tendril of her forked tongue… then more… and more… wrenching open the cervix as the girthier and girthier parts of Chrysalis’s tongue slid into Starlight’s womb, coiling in there like a relaxed snake, expanding her lower belly.

“F-f-fuck! I can feel… s-so… d-deep!” Starlight groaned, her hindlegs shaking and losing tone as her belly began to expand with tongue flesh, like a lumpy, squirming early pregnancy.

Chrysalis quickly reached a hoof down under her lover’s hips, keeping her from collapsing to the floor.

Now was the critical moment - when both Chrysalis and Starlight would be fully committed to one another, like it or not.

Chrysalis readied the mutagenic teratogen enzymes in her foregut, ready to shoot them down her tongue and flood the pony’s womb with the broodmare-preparatory substance. The wash of chemicals would baste Starlight’s uterus and race up her fallopian tubes to her ovaries. This would coax her gametes, her ova, her precious genetic repository to melt into a soup that would coat the walls of her womb… waiting for the insertion of brood upon brood of changeling eggs with which to mix their stored DNA and breathe powerful, genetically diverse life into the pair’s children. It would forever make Starlight sterile to ponykind (barring some powerful alicorn magics), and commit her entirely to Chrysalis.

But it was a two-way street.

Chrysalis was desperately low on these enzymes. And they were not the type that could simply be regenerated with sufficient time, energy, and food stores. No, a queen could only generate such powerful chemicals with the help of a very particular brand of changeling love to be processed by her exotic pituitary organs… that love was the adoration for a queen by her children.

Because of this, the mere mindless devotion of simple, un-DNA-mixed dronelings would not produce the required effect. A necessary evolutionary barrier that prevented ancient queens from simply flooding Equestria with mindless progeny, which necessitated the diversity of new DNA from interacting with other species.

But Chrysalis had now gone long without the love of her diverse children. Snatched away by this unicorn, her friends… and those ostentatious rainbow usurpers.

She had no more stores after this.

If this failed… she would simply wither and die, her genetic line a dead-end destined only for mindless, facile drones until something finally befell her… an empty husk of genetic expansion.

And so, Chrysalis too would be committed to her partner.

Was this really the pony being she wanted to be tied to? To invest all of that hope in? She really had not much stock of hope left. She would really be putting all her eggs in one basket, so to speak. Was Starlight really the basket that she would stake her very legacy upon?

She looked down on the quivering little thing, mere flesh and blood that quivered and shivered with her every move, like a puppet on strings.

And yet she was so much more than a puppet.

The subtle fall of her hair, the way her unkempt fur swirled and curled in messy tufts, the strangely pleasing mix of her palette. She thought over the mare’s history, how she’d fallen from grace so easily, with a reason so puerile as to make even a fuming toddler blush at its ridiculousness - becoming a supervillain because of a childhood friend moving away! Ha!

And what a supervillain! Mastering magics so advanced that not even alicorns could match her, subduing an entire town with only her charisma, snagging their cutie marks… their very souls without even a hint of mind control magic!

Ske rapidly skipped over the subsequent return to the ‘good’ side. All too common among the pony folk, who seemed to flip back and forth between chaotic evil and lawful good faster than that unconscionable draconequus.

And then she’d met Chrysalis.

Unseating her when she’d managed to capture all of Equestria!

After millennia of attempts, Chrysalis had succeeded, had every single thing she could have ever wished for in her hooves… and a throne of ultimate, total power.

Four alicorns had fallen in a single night.

Four.

And somehow… this little pony… had not only foiled her plot, wrenching those ill-begotten spoils from her… but had then taken everything precious and dear to her. Her very hive, her family, her legacy.

How could she not obsess over her in the coming months?

Chrysalis had poured over every detail of the unicorn’s past, every scrumptious tidbit. She’d studied her enemy day in and day out, slowly gathering more and more knowledge. Eventually, she knew the pony better than Starlight knew herself. And something, deep down inside Chrysalis had blossomed.

An unfamiliar feeling in the bug’s chitin shell, perhaps something she had never experienced before. Something she did not know, could not name.

She had suspicions as to what that emotion might be - but she would never admit it, could never admit it.

But here, with her climactic decision at hoof, that feeling solidified her choice.

‘Yes. I want her.’

Chrysalis released the slurry of mutagenic goo, throbbing in a thick bulge down her tongue that strained through her captive’s tight cunt with a stretching strain, before exploding in a splattering goopy glob of sticky, semen-like green slime.

“Uhnnngh! I… I feel it inside me… oh, Goddesses!” Starlight groaned.

Chrysalis felt the gland fully empty, not even a drop left - there was no going back now.

Starlight’s belly expanded with the sizable injection, which immediately went to work racing up the pony’s fallopian tubes, sliding into her ovaries with capillary action and causing all those egg-cells to shake free, melting into the pool of green changeling goo.

The slurry, now rich with proteins and precious segments of genetic material, sloshed back into Starlight’s womb, coating her uterine walls with the rich substance - a perfect agate for the new changeling eggs that would soon arrive… able to provide them with the food they needed to grow and develop, but even more importantly the DNA sequences that would make each new changeling a unique, beautiful individual, a new master race.

“Oh… oh fuck… I’m… I’m ch-changing! I can feel it!” Starlight moaned out, her guts twisting. “I’m… oh, f-fUUUuuu~ unnnnnngh!” As the final twisting changes to her womb solidified, a heaving hump back against Chrysalis tongue slammed out from the mare’s arched back. Whether driven by the earlier concoction, the changes to her womb, or the writhing, throbbing tongue in her pussy, Chrysalis couldn’t tell.

She could only tell that this was a big one. Perhaps the biggest she’d seen.

Her eyes rolled up into her head for a moment through the worst of her convulsive climax, slinking back down in a rolling, wild, wall-eyed gaze… her pupils now shifted into green, heart-shaped irises.

Her moans continued unabated, like a wild, feral animal on the ancient plains of an Equestrian grassland, recently covered and stuffed by her prehistoric stud. Her tongue lolled from its mouth, dripping saliva in such quantities that it was only rivaled by the amounts squirting from her pussy in sloshing sprinkler-like sprays, each one driven by powerful, clenching winks.

The wave of sheer pink thaumic energy hit CHrysalis with the force of a shockwave from a balefire bomb. The first sparking surge made every muscle in her body naturally react, tensing, and firing at random. The organs meant to process emotional energy as food were immediately overloaded, shutting down to protect themself from damage, which in turn sent the bug into a very literal total system shock.

She stumbled back, only to be hit again by the next wave, just as powerful, but longer-lasting.

It drove the changeling queen to her knees, then collapsed her onto her side.

She couldn’t control her body!

Not her legs, her wings… nor her tongue… which began to lumpy slop out of Starlight’s intensely milking, clenching, tight, little, still-orgasming pussy in heavy coils of dripping pink flesh.

‘I… I can’t… I can’t t-t-take it anym-... anymore!!!’ Chrysalis’s mind winked out and she let loose a loud, alien bellow. “Y-y-yeeeESSSSSSSS!”

Unbelievably, she felt her body begin to orgasm. A true orgasm. The first she’d felt in ages. Sparking waves of the sheerest pleasure was boiling through each of her muscles, tracing out her strange nerve fibers with overwhelming biological voltage, nearly burning them out entirely. Changeling’s possessed the most potent neurochemicals, dopamine, and metabolics… all needed to seduce and bewilder any creature on the face of the planet.

For a changeling, an orgasm was dangerous. Deadly.

Chrysalis shuddered, hooves kicking out wildly and wings buzzing randomly. A froth of saliva and poison dripped from her agape mouth.

But there was nothing she could do… except lose herself to the ride, the sheer pleasure, the painful release.

Her whole being, physical, magical, and spiritual was lost in a wash of pink lust. She couldn’t even be sure if her genitals were winking out in their own pleasure, or her ovipositor beginning to form and extend… or if those were just the misrouted sensations of her back or the underside of her hoof.

All of herself was one. And all of that one was pleasure.

She felt the dark edges of vision fading from her, the light fading out of her heart-shaped pupils, as she slowly dropped into unconsciousness, terrified that she might be expiring due to the orgasm, never to complete her plan… and that Starlight would die here as well… her lover… chained to the floor.

With a gasping final effort, Chrysalis managed to direct a beam of her short-circuiting horn at the throne. Shattering it and triggering a release mechanism that undid Starlight’s manacles.

At least, she would live.

Then… she slipped into darkness. And death.

Author's Note

OH NO!

She's dead! Starlight killed her! Killed her with her ORGASM!

She's an orgasm-murderer!

That orgasm should have been registered as a deadly weapon!
