From the moment you regained consciousness, you knew something was wrong. Very wrong. Whatever you were currently laying on was far too hard and cold to be your bed, and you could faintly hear the sounds of dripping water nearby. A haze seemed to cloud your thoughts, as any attempts to formulate a recollection of what had happened last night were proving to be a monumental task.
Opening your eyes, you were immediately greeted by more darkness, though you could just barely make out vague shapes of what appeared to be a cave as your eyes began to adjust. Raising a hoof to try and wipe the sleep gunk from your eyes, you were more than shocked when you could barely manage to lift up your arm. Glancing to the side, you discovered that you limbs had all been bound by some kind of strange gunk with the consistency of rubber, allowing for some give yet still holding you fast to the slab of rock you had been tied to in a spread eagle position.
Panic began to set in as your situation worsened. What was going on?! Had you been kidnapped?!
"Help! Somepony, anypony, help!" You yelled. Or atleast, that's what you intended to yell out, instead all that came out was a muffled, "Mmmppph!" A quick probe with your tongue revealed that your mouth had been bound by the same gunky stuff holding your legs in place, effective silencing any cries for help you might make. You thrashed around in a vain attempt to free yourself from your bonds, but all you succeeded in doing was making a lot of noise.
"Well, well, well... Look who's finally awake."
Your ears perked up slightly at the sound of a distinctly female voice coming from deeper in the cave. The sound of approaching hoofsteps fills you with dread as a pair of glowing green eyes suddenly pierce the darkness.
"Now that you're finally awake, the fun can begin..."
As the figure steps into view, you initially think she's a pony like you, though a very tall and lithe one. That is quickly proven wrong as you realize that instead of fur, her entire body is covered in a deep black chitin that almost seems to absorb all light in the room. A vaguely green membrane is wrapped around her midsection, the same membrane composing her ragged mane and tail as well. A pair of moth like wings sit on her back, several holes in her wings and body that allow you to see straight through parts of her. A sharp, jagged horn juts out from her forehead, just below a rotted crown that sits atop her head. As her glowing green eyes gaze upon you, she runs her tongue hungrily along the two jagged fangs protruding from her mouth.
Your blood runs cold as you immediately recognize the creature standing before you, having seen her face on Wanted posters set up around Canterlot. It was Queen Chrysalis, or rather ex-Queen of the Changelings, having lost her hive many moons ago. The very sight of her fills you with dread as your mind runs rampant with whatever horrible plans she has in store for you, each one worse than the last.
"Mppph! Mrrrph!" You grunt behind your gag.
She laughs as she approaches you, a wicked smile on her face as she stands over you. "What's wrong, cat got your tongue? Quite different from just how chatty you were last night..."
Like a bolt of lightning, it all comes rushing back to you. The time spent at the bar, spotting the light green mare sitting across the bar and smiling at you. The two of you going back to her hotel room, where her seductive and yet calming voice had made you feel safe enough to tell her everything about you.
Your eyes widen as realization dawns on you. Sweet Celestia, you had told her everything.
"That's right," Chrysalis's smile widens with glee. "You were so willing to tell me every. little. secret you had, especially when it came to what you love more than anything else in the world..."
You swear your heart skips a beat in that moment. Mixed in with the fear filling your body is a new emotion: embarrassment. You hope, no, pray that she isn't talking about what you think she is.
Your hopes are dashed, however, as her horn begins to glow a sickly green color and something is levitated out of the darkness. One look is all it takes for your heart to hammer away in your chest and, despite everything else, a tingling to start in your loins.
Floating before you is an already opened pack of adult sized diapers, perfectly sized to fit big ponies like yourself. Several folded up diapers are poking out of opening, as if begging to be worn.
Chrysalis moans slightly. "Ah, I can already taste it... the sheer amount of love you can produce from something so simple as a pack of diapers. You might even make that silly 'Princess of Love' jealous with how much you LOVE your diapers!"
Despite your best efforts, just hearing the word "diapers" causes an involuntary pulse excitement to course through your body. Any thoughts of possible torture or pain that were previously filling your head are swiftly being overshadowed by an avalanche of fantasies, all of them resulting in having a large, soft diaper taped onto you.
Likely sensing your growing excitement, Chrysalis pulls out one of the fresh diapers from the pack and begins to unfold it. Just the sound of the loud crinkling of plastic echoing against the cave walls causes the tingling in your crotch to intensify as your hips involuntarily start to wiggle in anticipation of what was coming up.
"Such a good thrall..." Chrysalis teases as she lifts up your back legs and gently slides the fresh diaper underneath your bottom. "... so excited to be changed into a fresh diaper. You better get used to the feeling of diapers from now on, my delicious morsel, because you'll be wearing them for a very long time after this."
So many conflicting emotions are swirling around inside you. Fear as being kidnapped, terror at what Chrysalis has in store for you, embarrassment at being reduced to little more than a cheap meal for the the love hungry bug... and an overpowering surge of sexual excitement that was currently pushing everything else from your thoughts.
As Chrysalis threads your tail through the back hole of the diaper, she leans in close and whispers into your ear, "Count with me, my little thrall. 1..." Pulling up the front of the diaper, she applies the tapes one after another onto your awaiting plastic prison. "2... 3... and... 4!"
As the last tape was applied, your hips begin to act with a mind of their own and start to thrust and move, your whole body tingling with excitement as you want nothing more but to press the soft padding deeper and deeper into your crotch.
"My my, so eager! Now that you're all comfy in your diapers, it's time for the main event."
You barely register her horn glowing again as something floats into your line of sight. The unmistakable form of a battery powered vibrator hovers an inch away from your diapered crotch, the sound of a slight buzzing filling the cave as it is switched on.
But instead of immediately giving you what you so desire, Chrysalis licks her lips as she leans in closer and says, "Beg for me now, you helpless little diaper pony. Tell me what you love more than anything else and maybe I'll reward you for your obedience."
You feel the gag over your mouth being removed. You know in that moment you can call out for help in the vain hope that someone, anyone will hear your cries and rescue you from this... This what? Nightmare? Horror? Fantasy made real?
Before you even realize it, your mind is already made up.
"I..." You begin to say, your mouth struggling to form the words. "I... I love..."
"Yes..." Chrysalis says with glee as she leans in closer, the very tip of the vibrator brushing against the front of your diaper.
"Say it..."
"I... I love..." Unable to contain it anymore, you shout, "I LOVE MY DIAPERS!"
"Such a good pony! And now for your reward!" Reattaching the gag, Chrysalis forcefully shoves the vibrator into the crotch of your diaper, the thunderous moan you make muffled enough by the gag that only the two of you would be able to hear it.
Time loses all meaning as waves and waves of pleasure begin to course through your very being, all of them radiating from the source of your desires. Your excitement continues to build and build as the vibrations from the sex toy grow stronger and stronger. Finally, unable to contain it any longer, you release everything into your diapers, the once clean padding sagging as it absorbed everything you threw at it. In that moment, you were in absolute heaven.
"Yes!" Chrysalis cries out as her mouth opens wide and a green mist practically pours out of her body and into her waiting maw. She moans almost as loud as you as her belly distends outward from the sheer flood of love you produce. After several moments that seem to stretch on forever, the outpouring of love finally ends as Chrysalis drops to her knees, panting as heavily as you were.
"So... So much love... so much love from just one pony!" As she regains her footing, her bulging belly jiggles slightly. "I could feed an entire hive from your love of diapers alone! Yes, your love of diapers will feed me for an eternity!"
You barely hear what Chrysalis is saying, too exhausted from what was quite possibly the best orgasm you had ever experienced in your life.
"Hmmm... I should really change you..." Chrysalis remarks before shaking her head. "Nah, I think I'll keep you like that for a bit longer. Let you stew in your love for a bit to enhance the flavor." Reaching up, she presses a hoof into your squishy diaper, eliciting one more gasp of excitement from you. "Sleep well, my little thrall, I have big plans in store for you..."
As you feel a sudden drowsiness overtake you, likely from a mix of such a powerful orgasm and Chrysalis's magic, two thoughts simultaneously go through your mind.
The first is the hope that someone will eventually notice you missing and come rescue you from Chrysalis's clucthes.
The second is the hope that they take their time doing so, hopefully long enough for you to experience a few more orgasms like that one.
