She shifted back until she reached the limits of her manacles, cruel iron biting into the fur of her ankles as Chrysalis advanced on her. At first, the queen rolled her eyes with a droll evaluation of her captive’s hyperbole, but quickly they flashed with a lusty and growing sadism.

Unfurling inch after inch of her long, pink tongue, coiling it playfully as it hung halfway out of her mouth, dangling almost as long as her neck.

“Oh no. No no no, stay ba-hrgkk…”

Chrysalis cut off her prisoner’s complaints with a well-timed lunge. She used the pony’s gaping, complaining half-yell as the target for her prehensile and rapid tongue, slipping into her warm mouth and engorging her flesh, rapidly growing it from a mere, worm-like tendril to a thick, thrumming bundle of muscular cord - rapidly stretching her jaw with her invasive organ.

Chrysalis grinned despite herself - she knew that she should only be feeding Starlight at this point, shouldn’t be making more of this than the rather unique changeling method of feeding than it was. Those squishy sapient surface-dwelling creatures put far too much stock in the meaning behind their oral congresses, going so far as to make these ‘kisses’ the object of much effort and often the trophies of their romantic endeavors.

But knowing this impact that it had on Starlight, the meaning that the pony gave it… tasting the raw shock, embarrassment, confusion… the shame that came with the act made it so much more exciting, even for her. She couldn’t help but linger in her foe’s mouth, swirling and filling the cavity of her muzzle, spreading her slimy tongue to press against her teeth, the roof of her mouth, pressing down against Starlight’s own squirming, unsure tongue… exploring every crevice with delight.

“Mmmgnh! Mnnf!” Starlight’s ineffective groans did little, even punctuated with her straining, bulging eyes - incomprehensible complaints, no doubt. The kind that Chrysalis wouldn't even bother with a reply if she could hear them.

She’d soon stop even that mumbling, though.

With a delicate extension of more of her hitherto withheld tongue, she began to snake the end of her probing muscle down the back of Starlight’s throat. With skill, she located the entrance to Starlight’s esophagus, waited until the pony had taken a wheezing gasp of air… then plunged in heartily.

Though she didn’t need to, Chrysalis leaned in as she began to plumb the depths of Starlight’s throat - there was something about the intensity of bringing her own slit-eyed pupils closer to the smaller pony’s twinkling, fear-filled purple irises that excited her.. And it was definitely making her pet’s heart rate skyrocket - as their noses touched she could sense it pounding away as if the unicorn had just finished running a sprint!

Down, down she pressed her tongue, well past the depth that any stallion might have ever reached with a phallus. That thought slipped into Chrysalis’s mind rather unexpectedly - she really was getting a bit excited from this, wasn’t she?

With a little crook of her eyebrow in self-reflective amusement, she succumbed to the whim that had so inadvertently popped into her warped being. Swirling her tongue into a more cohesive tangle, she began to form what she assumed to be the average size of a unicorn stallionhood… at least the size of those she had assumed when donning disguises herself. It was a far cry from the actual density and shape of a stallion cock, her tongue was only able to shift and form so much without actually expending changeling magic... but it served as a rough approximation.

Chrysalis cackled to herself happily as she carefully moved her tongue up and down in the deep confines of Starlight’s gullet. She wasn’t rough or crude - she had no intention of harming or even making the experience unpleasurable for her delicate little toy, but it was still amusing to think that she was now ‘tongue-fucking’ her… softly grinding her phallic-like tongue-snake so deep inside the pony’s neck that the bulge could be seen spreading all the way down to the top of her breast bone.

There was no pleasure in it for Chrysalis. Physical pleasure, that is. There were no sensory nerves in her tongue - though she supposed she could have sent some changeling magic to put some there, to make the tip or the swirling sides of her tongue as sensitive as a coronal ridge or clitoral bud… but that would be gauche, physical pleasure was only the delight of the inept changeling, the novice.

A Queen delighted in the true spoils of the hunt - the feeling and emotions from their target.

And yet, this meal was lacking thus far.

Oh sure, there was the lovely aperitif of confusion, shame, surprise, discomfort. Titillating sprinkles of interest that were not unlike a rich soup served before the main course. But she was not quite ripening into the palette that Chrysalis desired.

There was no desire, nor hopelessness, no rage or indignance. Obviously, no love… but Chrysalis was not so naive as to expect that.

Extracting anything even like to such a rare flower would take months of cultivation, snipping off the emotions that might lead a changeling captive down any number of myriad paths as a gardener might snip off the branches and leaves of a bonsai tree, patiently awaiting the artistic final result.

But now that she was here, in the moment, Chrysalis was finding it hard to… resist. To hold back from the screaming desire to take her pleasure, now.

There were ways of course, crude and effective. Ways that she might have scolded a younger infiltrator for using, because of the inefficiency and lack of art - using the changeling body’s capability to create aphrodisia, only to feed on the inevitable result… was not unlike bleeding yourself out of your left foreleg to fill the IV line implanted in your right… sure there was some benefit, but it reeked of novice desperation and impatient need.

Like the impatient need she felt burning within her now.

She was the queen, after all… if she should so choose to enjoy her snack as something more like a junk-food treat than a healthy, nutritious meal… she had every right. At least, that was the weak, quick argument that she used to justify her addition of estrus-inducing enzymes and love-eliciting hormones to the royal jelly stewing in her forebelly.

Too late to hesitate now, with her tongue in Starlight’s belly.

A thrum of her wings propelled the goo down the capillaries of her tongue in a fat bulge of nutrients. Starlight’s eyes shot open another notch and her eyes shrunk even further as the round bulge slid down her throat before spilling into her pony-belly. The viscous, foul-tasting spill of goo splattered into Starlight’s gut. Chrysalis knew that most ponies could scarcely bear the taste of royal jelly when served to them, the formula had never been so vainly created as to account for something as trivial as taste. Thus, the tongue-injection direct into Starlight’s belly was a mercy, a benevolent bestowal for her little pet… giving her all of the rich, healthy nutrients without any of its aftertaste.

Though she didn’t like to dwell on it, a small part of her hoped that Starlight would appreciate the consideration.

She couldn't tell at this moment, not from the pony’s eyes, which watered and trembled as splash after splash of healthy goo was deposited into her digestive tract, her belly swelling ever so slightly - as if she had just polished off a full Hearthswarming meal.

Her quivering irises soon slowed, relaxing and dilating as the heavy-drugs in the meal began to take effect. The bowstring-tight tension in her sinews began to languidly unwind, muscles shifting and going into a tonus state, as their centralized control system unwound and released its hold.

“MNnngh… glrk…” The unicorn’s mouth was moving and slipping around the changeling’s tongue, as her throat constricted and swallowed - little choking clenches of her muscles trying to draw more of the fluid down into her belly, wringing the tongue-phallus.

Chrysalis let the corners of her grin lift. It appeared that Starlight had a particular predilection for the aphrodisiac ambrosia, a weakness that caused the fluid to take effect with more force and with greater alacrity than one could otherwise have expected.

As fun as it would be to continue pumping her little filly with the nutrient (Chrysalis had plenty to spare) until she swelled up like a fat, larval, changeling foal… she knew that the pony’s lungs must be burning for oxygen.

There was no way she’d risk any brain damage to her beloved captive - the jelly could sustain the body for some time, but Chrysalis had little desire to dominate a drooling shell of a pony. It was Starlight that she wanted to corrupt and exploit - not merely her corporeal shell.

She quickly shrank the width of her tongue, withdrawing it in a slither from the slender pony-throat with a steaming exit from the gaping muzzle. As soon as it had cleared Starlight’s jaws, a deep wheeze stretched Starlight’s nostrils, as she drew in a hearty, burning breath into her air-starved lungs.

“Phew… ah… phew… ah…” Starlight’s breast heaved in and out a few times, her heart pounding so hard in her breast that Chrysalis could see if bumping through her skin, could hear its infrasonic pulses with her sharp, insectoid ears. “Hah… hah… wh-what… what did you do to me?”

Chrysalis arched an eyebrow, shaking her head as though it was a fool’s query. “I fed you.”

Starlight’s brow knitted together in confused anger. “N-no… hah… what… mmnff!” She moaned, reaching a forehoof back to stroke her belly. A pulse of muscular tension thrummed through her, making her arch her spine like a cat, her coat-hair starting to stand on end in arousal and for heat dispersion, a sweat forming on her brow, her tail starting to swish higher and higher in the air, involuntarily fanning herself.

Chrysalis’s sharp eyes were twinkling with happiness as she watched the effects bubble through her captive, so unsubtly poignant, so obvious that even a fumbling colt on his first date would notice. Flaring nostrils gulping in lungfuls of air, a mouth hanging open to let a drooling, blood-pink tongue hang from one side, rivulets of sweat that slid around the outlines of dewy, unfocused eyes.

And further below, a body that continued to twist and cavort, as if it were uncomfortable in its own skin, each movement raising the rear end of the pony’s bottom as it lowered its front… the damp mop of a tail raising more and more with each passing moment, hoisted slowly by the wiggling, fleshy dock like a guardsman hoisting a flag.

She was witnessing Starlight go into a raging, burning, induced heat. An estrus of weeks condensed into its most wanton, desperate moments before her very eyes.

“Did… hah… did you… put… put your eggs… hah… in my belly?” Starlight groaned, still puffing as she rubbed her hoof over her stomach. Strangely enough, the question seemed to be partly outraged… and partly hopeful. Chrysalis could tell in the strange swirl of chaotic emotions pouring off of Starlight’s aura that mixed in with the fear and fury and having had her body suddenly violated… was a growing, burning need to bear progeny.

Chrysalis’s laugh was more like a bark than a giggle and her reply was just as sardonically cutting. Any pony watching would have marveled at her ability to sound exactly the same despite the fact her tongue was still hanging a good two feet from between the lower fangs of her jaw. But she had much experience instructing and explaining while still making other use of her tongue.

“Oh Starlight, didn’t your teacher Twilight explain that babies don’t come out of your belly?” Chrysalis cackled again. “Now, I know when a mare gets pregnant it looks like she’s got a big stomach, but it’s actually a different organ which has been stuffed with foal.” She roared with laughter at her facetious quip before continuing, “It seems I have much to teach you about your body, Starlight.”

“Umnnf… n-no… not what I meant…” Starlight mumbled, her eyes rolling left and right in their sockets as she struggled to maintain focus amidst the surge of endorphic neurochemicals that must be basting every fold and crease of her gray matter at this moment. “Ah! S-stop!”

The sharp shout came as Chrysalis's long, snaking tongue made a caressing flick underneath the nape of Starlight’s neck, leaving a slimy trail of saliva as it pressed into the shorter fur there, only a brief pause as it coiled up and over to her croup.

“Are you sure, my little pet?” She only just managed to hold back the laughter, though the mirth bled through in each uttered syllable. “There is so much I could teach you about your feeble biology… you never really get to know a body until you’ve actually morphed every element, every living cell of it personally.”

She let her tongue trace down the side of Starlight’s barrel, worming in an s-like pattern rather than simply snacking or taking a more direct route, happy to linger over any spot of sweat or the bony bump of a protruding rib, making sure she intimately studied the body which she had yearned for so long.

“P-pleease… gah!” Starlight gasped, hanging her head suddenly as a quiver ran through her.

Chrysalis could sense the building tension in the pony’s body, like a spring being wound tighter and tighter in a jack in the box, restrained energy that snapped and shifted upon itself as it was compressed and heightened, each readjustment sending out earthquake-like trembles through the whole of Starlight’s being.

She could taste that built-up desire too, the chemicals clear and poignant in each lapping lick of sweat as her tongue coiled down to the mewling thing’s hipbone, sliding under prematurely, ahead of the rear legs, squirming across Starlight’s belly with an exploratory, languid, lick.

“H-hee h-hee… g-gahh! N-noo!” Starlight moaned as the delicate touch of tongue against her nearly-fur bare tummy tickled a chuckle out of her.

“A dangerous thing, tickling.” Chrysalis hummed into her captive’s ear. “For some reason, it seems to slip past all of our guards… releasing our body to react on a more… primitive level.”

Chrysalis pumped more saliva down her lengthy tongue - no easy feat, and she was sure that she would be dehydrated by the end of this, but it was more than worth it for her beloved captive. Again, she slipped the probing, sharp-forked end of her tongue around the pony’s belly, finding the strange knot of flesh that was Starlight’s belly-button. She wriggled into the cute-little crevice - an innie, of course (though she might endeavor to change that) - and briefly toyed with the idea of slipping into the pony’s thoracic cavity through the sealed orifice, of playing with her puppet so intimately that she might actually inhabit her body with her tongue.

“H-ha, hahaa! N-no… noooounnnnnghhhh!”

But Starlight’s body-wracking giggles pushed the thought out of her mind. Starting as an irresistible chuckle and growing into body-shuddering laughter, the first cracks in the dam began to appear in Starlight’s hitherto spartan resolve. It was so difficult to maintain control of swollen and quivering muscles, organs, nethers… when one was laughing.

And Chrysalis could smell it immediately. The sweet honey scent of a mare in burning heat. Tangy and cinnamon sweet. Starlight’s giggles had coaxed the mare to clench and unclench her plot, releasing a small trickle of clear love-nectar to race down her inner thigh and be wafted like a fog by her thrashing tail.

The queen’s powerful changeling olfactory system quickly snagged the molecules from the very air, breaking and dissecting each of the complex elements down into component parts. The data quickly told her that the mare was in estrus - an ovum ready and able to be fertilized within her, and was in burning desperate need to have that biological imperative sated.

“Oh my, my little Starlight.” Chrysalis let her tongue slide away from the belly-button and slip lower, quickly finding the slick, bare skin of the unicorn’s teats.

‘Hmm…’ Chrysalis mused internally, “I had always thought she was a bit more busty - I always assumed as much when I took her form… no matter, I’ll fatten her up nicely.’

Her pink tongue found its way into the unicorn’s cleavage, sandwiching itself between the glorious mounds like a happy sausage into a hotdog bun. But it quickly raced up those pert hills, finding a firm, dark purple, eraser-shaped nipple that it could constrict… before flicking at its sensitive end with the wiggling ends of its forked tip.

“Ahn… ah!”

Chrysalis shivered herself, feeling the waves of pink, emotive energy thrumming off of the unicorn, drowning out the surging red rage and bitter yellow fear that had been so potent only minutes before. Starlight was quickly losing herself to the feel of the skilled insectoid tongue as its end teased her nipples, and its length coated her sides and crevices with a tingling, warming saliva.

Chrysalis began to withdraw her tongue, making sure that in the whip-like retraction she managed to flick the untouched nipple, leaving it also coated in a layer of her stimulating, sensation enhancing saliva… She wanted to make sure that her little Starlight’s every pleasure center was on fire by the time she got to the main event.

Satisfied that she’d stimulated her prey enough for the next phase of pleasure-torture to continue, she strode to the mare’s shaking plot, still thrust up in the air as high as it could go, with Starlight standing on her hoof-tips, presenting herself with desperation to some invisible stallion that wasn’t there.

As Chrysalis turned the corner, preparing to take in the sight of her toy’s well-aroused plot, the unicorn’s tail briefly ducked down in shame, a vain attempt to hide her embarrassingly aroused backside from her jailer’s gaze.

But in the same moment that it lurched down, a wracking spasm and quivering shiver sent it rocketing back up to its fully flagged angle, accompanied by a gasping sigh from the sweating, drooling unicorn.

Green, cat-like pupils flashed with lusty desire as it took in the whole of her captive’s despairing want. The mare had such a delectably squishy and tight ponut, framed by her plump glutes - a quivering knot of flesh that was squeezed so small that in that moment Chrysalis was sure she’d never given her tailhole to a suitor, or even a toy.

And beneath it was the real gold.

Chrysalis’s fang-sharp smile gleamed a shade brighter.

Author's Note

Well... at least she's not hungry anymore, right?

If you were in Starlight's position (restrained by a love-hungry Changeling) would you want to be injected with their love pheromones and 'lose yourself' to the need? Or would you rather be fully present?

Let me know!
