Author's Note

I there's anything here that you do not like or do not want to see...

Now's your last chance to back out!

But, if you're in the mood for a fetishy story and want to read this, you've come to the right place.

With some extra pounds and pressure added!

"Hi, everypony! This is a super duper fun-tastic day we're having, right?" Everyone cheered in tandem as they were woken up to freshly baked goods; some of them were causing some of the ponies in line to salivate. They wanted them, and they wanted them badly! "That's okay, dokie, everypony! I'll be able to put a smile on all of your faces!"

"phew! Serving all those ponies can sometimes get tiring but worth it. I guess I'll get to see what Twilight is doing; that'll be a lot of fun!" Pinkie giggled as she left Sugarcube Corner searching for the Castle of Friendship. On the way, however, she overheard Lyra and Bonbon talking.

"Hey Bonbon, don't you ever wonder what it's like to get older? You know, wrinkling skin, jowls, cranky attitudes?"

"Ok, Lyra, one: rude, two: no, I don't worry about it, and three: Why ask me?"

"Well, I kinda worry about the fact that one of these days, I would no longer be here to make you happy. Or anypony else, for that matter. Doesn't that scare you just a little?"

"Actually, no, Lyra, it doesn't; if it's my time to go, then it's my time to go. There's nothing you or I could do about that." This conversation had stuck in Pinkie's mind for the rest of her trip to the castle.

Knock knock! "Hello, Twilight? Starlight? Spike? Anypony in there?" Pinkie had then waited, humming a jolly tune to herself, with half as happy bounce to her step, still worried about what Lyra said earlier. Pinkie then looked glee at the double doors opening to reveal Spike's right arm and head poking out from the inside.

"Sorry, the Castle's library is closed for maintenance- oh, Pinkie Pie, welcome, come on in!"

"Thank you very much, Spike! I need to speak to Twilight for a tiny, itty bitty minute. She wouldn't mind, right?"

"She's working on an important experiment. But sure, I don't think she'll care."

"Yay! Thank you, Spike!" Pinkie had then reached out to hug the drake and trap him in her soft and furry embrace.

"Yeah, no problem, P-Pinkie! But can you let g-go of me? I-I can't breathe!"

"Oopsie, sorry about that, Spike."

"It's fine; just go on in."

"Yay!" Pinkie did just that and hopped into the castle, now speaking to her friend Twilight, with only one objective in mind. She heard the tell-tale signs of frustration down the hallway, near the leading laboratories and central libraries. If she knew those groans well, she knew Twilight was close to her now. "Okie Dokie lokie, it's time to go and ask Twilight for a small little favor!"

When Pinkie approached the door leading into the castle laboratory, she saw a note on the door that read 'If it isn't an emergency, or essential, please don't disturb me, thank you!' This, to Pinkie, was an invitation. So she did. Knock knock! "Hey Twilight! I gotta talk to you; it's essential!" Pinkie did read the sign, right?

"Ugh, ok, Pinkie, come on in, what is it?"

"Hey there, Twilight, I was hoping you could..."

"Out with it, already! I've got an experiment to run!"

"Well, I was hoping you'd want to... use me as your test subject for an experiment. Would that be okay?"

"Um... Pinkie, are you feeling alright? This isn't like you at all. What experiment did you have in mind exactly?"

"Well, what exactly are you doing here?"

"I'm glad you asked; this is an experimental potion that'll expand matter, proportional to the test subject it's applied on."

"Mhmm!"

"Repeat back to me what it was I just said!"

"You said: I'm glad you asked; this is an experimental potion that'll expand matter, proportional to the test subject it's applied on. See, I've been paying attention."

"Ok, I suppose that would do. What do you need this for anyways?"

"Well, what's the extent of its absorption abilities? Can it help me to preserve my age? Cause, that's what I was kinda worried about, dying before I was ready to go."

"Um... well, Pinkie. I... I just don't know. You do realize what it is you're asking me, right?"

"Yeppers, a potion to make myself live longer than usual. Something to expand my life."

"But this current experiment only expands size and matter, not the overall longevity of life."

"Yeah, I know that now, but how do you know if that's all it can do? This is an experiment, right?"

"Yeah, I suppose you're right. So what got you so interested in my potions all of a sudden? Why do you even want to live longer?"

"To keep everypony happy for a very long time!"

"That's... exactly the answer that I should have come to expect from you of all ponies, Pinkie!"

"So, does this mean you'll do it for me?"

"Yes, fine, I'll do it, Pinkie, but the first sign of discomfort you feel, we stop this experiment immediately, understood?"

"Okie dokie lokie, Twilight!"

"Alright then, take this potion and apply its solution to your body, like a form of a shampoo. I'd recommend using it during a bath. The effects will kick in easier when the compound can enter your pores. Do you understand this, Pinkie?"

"Yep, take this bottle with me to my home and take a bath, right?"

"Yes! Good, you're paying attention."

"So I'll be able to tell you how I'm feeling tomorrow, huh?"

"Exactly, Pinkie! We'll see what effects this'll have on your body!"

"Okie dokie lokie, Twilight! And for what it's worth, thank you for helping me with this, Twilight!"

"No problem, Pinkie. See you back here tomorrow, ok?"

"Yep, ok!" Pinkie had then grabbed the bottle, put it in her mane, and left the laboratory to head home for her bath!

"Okie Dokie, so I apply this here, here, and here. The bottle says only to apply it where you think you'll need it most. Why not everywhere?" Pinkie had done just that; she liberally applied the solution all over her body. Suddenly, she felt a slight tingling sensation from her head to her hooves. "So, now what's supposed to happen? Do I get huge and sexy now? Cause that'll surely be the cherry on top of my extended youth." Pinkie felt like her body was expanding, yet as strange as it was, she hadn't grown bigger. This did disappoint the pink party pony some, but she didn't pay it too much mind; this was an experiment; after all, mistakes were par for the course.

"So, now do I tell Twilight my discovery? I guess that's the best thing that I could do. But why do I feel hungry all of a sudden? Like really hungry, for like magic hungry!"

The next day, Pinkie Pie was heading to the castle, as agreed yesterday, to tell Twilight about her discovery and progress. She approached the threshold of the castle's double doors and heard some voices in there; one of them sounded very familiar to her, like Cadence familiar. That was just peachy for her; she could check up on her experiment and say hi to the Crystal Princess. Knock knock! "Hey, Twilight! I'm here to check up on my experiment!"

The door opened to reveal Twilight looking at Pinkie before saying, "Hi there, Pinkie. Come on in; Cadence had just showed up for a visit. I was just speaking to her for a while until you showed up."

"That's super duper amazing, Twilight. Oh, and hi, Cadence!"

"Hello there, Pinkie. Long time, no see!"

"Yup, so did you come by to say hi to everypony? That's so thoughtful of you!"

"Well, yes, Pinkie. Shining is currently managing the Crystal Empire, so he's not here. So I thought it would be a great idea to do so since it has been a long time since I've seen you guys."

"Well, that's awesome for you to do! So back to what I came here for, Twilight."

"Oh ponyfeathers, I must run into town and complete some errands. The list is rather long, so I might take a while to get back. You and Cadence could catch up while I'm away."

"Okie dokie lokie, Twilight!"

"Great, I'm off now; you two have fun!"

"Yay! Fun!"

"Alright then, Pinkie, what game did you say you wanted to play again?"

"Truth or dare, silly!"

"Oh, right. I forgot, silly me."

"It's ok. So what's it going to be, truth or dare?"

"Wait, we're starting now? Don't we need to spin a bottle first?"

"Nope, not for this game; we don't!"

"Ok, alright then, I'm feeling adventurous today, so dare."

"Are you sure about that, Cadence?"

"Yep!"

"Okie Dokie lokie! I dare you to give me a big ol' hug!"

"Um... alright then, Pinkie. If all you wanted was a hug, you didn't have to dare me into it."

"Hugs, hugs, please!"

"Ok, fine, here it comes, Pinkie!" Cadence reached out her hooves to hug Pinkie as she returned her warm and loving embrace. But then, she felt... weird. Pinkie was beginning to grow from the affection of the hug alone. The only creatures that Cadence had ever encountered and known that could do this were changelings. Pinkie couldn't possibly be her, could she? Cadence was also feeling weaker for some reason. What was Pinkie planning to do to her? She didn't even want to find out.

"Mmm, so fuzzy and so warm! It's filling me up so much. What's t-this glowing pink stuff called again, love magic? No wonder those changelings wanted this stuff so much; it feels great to have filling up inside you."

"U-um, Pinkie? Could you please let go of me? I d-don't feel too comfortable here."

"That's okay, Cadence. I'm not going to do anything bad to you, I promise."

'Then, if Pinkie isn't a changeling, what happened to her? I do recall her and Twilight saying that they were running an experiment. Could that be what's happened to Pinkie here? Regardless, I need to get her off me before she drains me dry here.' Cadence was now beginning to worry for her safety; love magic was very potent and very addicting magic. You didn't necessarily have to be a changeling to get hooked on the stuff. Their snuggle session was slowly turning bad for Cadence. She needed to act fast before Pinkie got addicted to its power. And that was very easy for anyone to do.

"Mmm... so snuggly, so fluffy, so warm!"

"P-pinkie, please get off of me, now!"

"No way, Jose. This feels way too good to stop now!" Pinkie had then grown larger and broader, especially on her flanks. Cadence was getting increasingly worried, each second that had passed stuck in her embrace. She couldn't wiggle herself free; Pinkie was like an intense vice, holding you into herself and never letting go. Then, Pinkie was about five to six times as big as Cadence; her flanks were double that. They looked as if they could flatten her, then bury her entire body between them. "Oh my Celestia above, s-so bucking g-good.!"

"P-Pinkie... p-please!"

"Hold on; I'm almost done with my best-est, best friend snuggle time!"

'O-oh dear, I'm nearly drained dry, here. I-I can't use any of m-my magic. N-not good at all. T-Twilight, if you're almost done, please get back here quickly; I can't hold her off much longer!' Then, to Cadence's horror, Pinkie's bowels made an aggressive rumbling noise. She knew exactly what was about to happen and couldn't even plug up her nose. She could only wince and brace for the presumably foul smell.

Deep gurgling and Rumbling noises!

"Oh boy! I-I feel like I have to fart, really bad! I hope you don't mind, Cadence!"

"P-Pinkie, p-please don't!"

"Too late for that, Cadence. It's coming out!"

'...Oh clop!'

Brrrptt!!!

To say that the smell would have been foul was an understatement; the saturated stench of beans, broccoli, rotten eggs, cheese, and swampy sulfur had assaulted her sense of smell. This caused Cadence to feel dizzy from Pinkie's noxious fart potency. She collapsed when Pinkie had released her from the snuggle session, finally. But Cadence wasn't feeling too good. She was weakly gagging and writhing on the ripe stench of Pinkie's fart; then Pinkie had an idea; she should play with Cadence some more; that would be a lot of fun. Way more than just a simple hug.

Coughing and Gagging! "Oh god, it really stinks, badly. P-Pinkie, s-stop this m-madness, p-please!"

Frrrptt!!!

"Nope, I can't stop now, Cadence. This party is just about to begin for you!" Pinkie had then re-positioned herself, so the shadow of her gigantic ass was covering all of Cadence's body and vision, much to her extreme horror. All she could do was stare deeply into the endless pink abyss of Pinkie's sweaty ass. "Comin' down, Cadence. Time for the party to begin!"

"N-Nooo!" Cadence had reached her right foreleg out in despair as she then tried in vain to use her other foreleg.

"Are you seriously trying to hold back my big booty? Don't be silly, Cadence!"

"I-I may not be able to hold you b-back forever, b-but doing anything w-would be better than doing n-nothing. Augh! W-Why're you so bucking heavy, Pinkie. Oh no!"

Bompt!

Cadence's hooves were sinking into Pinkie's supple ass flesh. Everything had hit the loving princess all at once; the weight, the smell, and the feeling of being helpless. She couldn't keep this fight up much longer. It was like holding back two massive, heavy boulders from crushing her flat under them. "My booty's going to getcha, Cadence! Oh, I've got another big boomer to give you! This one's going to stink!"

Deep gurgling and Rumbling noises!

'...Oh no! Somepony, please help me!'

Prrrptt!!!

"Ugh, that's pungent. Oh no, don't squish me, Pinkie! N-No, nooo!"

Crunch!

Giggles! "Ahh! There we go, Cadence. Nice and soft! This is so much fun and so hot, too. Just you and I, here together ~"

"Mmmpth!" 'Y-Yeah, whatever you say. Oh man, the stench in her flanks is powerful! And her sweat and body heat is basting me in here. Please, anypony, I need help! It's too much ass for me to handle!'

Bouncing and Crunching noises!

"Oh! Oh yeah, Cadence. Deeper for your best friend! W-When you squirm in t-there, it feels j-just super d-duper, Cadence."

Bouncing and Crunching noises!

"Mmmpth! Mmm!" 'Ugh, Faust above, this is j-just horrible. Why? Why does this have to be so torturous? P-please, make it stop, somepony!"

Bouncing and Crunching noises!

"Oh yeah, I've got more butt fumes brewin' for you, Cadence. Take a nice and hearty whiff for me!"

Deep gurgling and Rumbling noises!

"Mmmpth!" 'No, no more farts Pinkie, please! They really Stink! Mercy, please have some mercy on me! Oh no, her flank fat is squishing outwards now. N-No more!'' Cadence was now on the verge of tears; this was so bad for her to endure. Then suddenly, she felt her wings disappearing from her back. Oh no! Was Pinkie seriously stealing both her love and alicorn magic?

Prrrptt!!!

"Ahh! Oh my goodness, yes. This feels so good, Cadence. And are those... they're, they're wings. I have wings now. Yipee! Thanks, Cadence; with your magic, I'll be an alicorn in no time!"

Bouncing and Crunching noises!
Brrrptt!!!

"Mmmmpth!" 'So t-this was her p-plan all along? To become an alicorn? B-But, what's going t-to happen to m-me now? Ack! Some of her farts got into my mouth; I can't believe I just swallowed some of her vile gas.' Then, to Cadence's horror, she felt her horn shrinking back into her head like it was disappearing from view. Not her horn, anything but that.

Bouncing and Crunching noises!
Frrrptt!!!

"Whoo! That one felt nice and thick! Hey Cadence, how're you holding up down there? Boy, oh boy, would I love to be you right now! I'm so jealous of you, Cadence."

"Mmmpth!" 'P-please, d-don't be, Pinkie! I-I can't think straight anymore; her t-toxic stench is clawing its way into my mind, smothering it and me into it. C-can't keep this u-up much longer!'

Bouncing and Crunching noises!
Prrrptt!!!

"Ahh! ~"

'N-no! P-please... I-I need h-help... I... mmm.' That was it; Cadence has passed out from the awful anal abuse she's forced to take. With her horn and wings completely gone, she was reduced to just being a mere earth pony! This was her life, or what was left of it—being a permanent plaything to a now sadistic Pinkie Pie: Princess of Laughter!
