Author's Note

I'm aware of how rapey and screwed up this might be. I really don't care. This is supposed to be an oddball and degenerate story with laughter as the main fetish component. I know it will only suit the needs of some and others might find it offensive.

But I also know people won't read this and respond negatively anyway. Unless it's constructive criticism. I probably won't care. And of course, as a disclaimer. All characters are 18+.

She Will Bring Joy to All

A scientist, a once beloved pony who brought cheer to all, sat in a dark empty room. She was observing her many lit monitors as she sat on her tail, letting it twitch along her nethers as she focused on three particular screens. She moaned a soft and sultry moan, staring quite evilly upon her three screens of choice. She was adorned in just a lab coat, allowing her to give her large breasts a gentle rub when she was feeling particularly aroused. "Well, looks like they're prepped. Sheesh, they look so unhappy. Looks like I'm going to have to fix that" said the scientific mare, licking her lips with lust. The scientist was none other than Pinkie Pie. A pony who once was the premier party pony of Ponyville, but upon becoming obsessed with making ponies smile by any means, she had decided to seclude herself into bitter loneliness until she could perfect her art. Which, given how she actually needs happiness and friendly faces around her to keep herself sane. Probably made the plan rather dodgy.

With her growing seclusion affecting her mind, the puffyness of her mane, and her view on happiness herself. She began to look into cruel scientific methods in bringing forced joy and laughter to the masses. Even finding benefactors to help fund her crazy crusade. She eventually was able to build an entire secret facility to fit her needs. The facility itself would be used to test various ways of making ponies smile, laugh, feel good about themselves, and bring ultimate pleasure. Of course, by this point, those goals had become perversely twisted by her own solitude and manic thoughts. Becoming crazy enough to even find her experiments arousing. And with her backers being willing to give her fresh test subjects by her demand. She never ran out of ponies to test her methods on.

"Awww, poor Sweetie Belle. You look so sad, don't worry. When I'm through with you. You'll never want to stop laughing. It'll be a real gas!" Pinkie cheered as she observed the naked white pony, who had since turned 18 and developed into quite the curvy yet dainty little specimen, with good sized breasts to boot. Pinkie then pulled a clipboard from her coat and slid a pen out from the board's clip. She read the paper that was clipped onto the board. It was a list of experiments and names. The first name was Sweetie Belle, listed under an experiment described with "Laughing Gas and Giggle pet". Sweetie Belle herself was in some sort of white room. Walled off by clear glass, with ventilation set up near the back corners and holes placed everywhere along all the walls but the glass one. They were also placed along the floor.

She then looked upon the screen with a familiar caramel pony. Bound to a chair in which the seat looked like swiss cheese with all it's holes. She was struggling to escape, but to no avail. She too was naked, with Pinkie taking special notice of her flat chest. "boop!" Pinkie said as she poked her finger on the screen, where Scootaloo's nipple was. "Scootaloo, I feel really bad for you, it's like you never grew up! You're still flat and your wings are so small. No wonder you couldn't get into the Wonder Bolts. Well, don't worry. Pinkie will be there to cheer you up" Pinkie again cheered, as she looked upon the second experiment set on the list. "Scootaloo - Tickle Torture/Slavery". Pinkie then laid back on her chair with a frown as she rested her head on her hand. "It's a poo that I have to give you up after this, I really wanted to keep you for more experimenting. But sometimes ya just gotta follow the guys who sign your checks. Ah well, There's still the Apples." Pinkie said, as she shifted her view to the third screen.

She looked upon the last screen with very hungry eyes. On the last screen was Applejack, tied to a bed, struggling even harder than Scootaloo was. She had already worked up a sweat trying to escape, but with her sister placed in a cage just out of reach, she would give it her all to break her bonds. Applebloom herself had filled out almost as well as her older sister, with breasts as plump as apples. "Applejack, Applejack, Applejack." Pinkie said with a sigh "You've been doing that for hours. You're not going to break through my magical metal bands. But keep trying! You look so sexy when you sweat like that! Oh ho~" Pinkie Pie tittered with sexual intent as she looked at the last experiment on her list. "Applejack/Applebloom - Pleasure to Laughter Transferal Test". Pinkie Pie then looked upon Applebloom, who had tears in her eyes as she even wondered what was going on. She had tried breaking through her cage a few times, but she wasn't as strong or well toned as Applejack either. She was afraid for Applejack as well, afraid that whatever was lined up for her was worse than her own fate. "Applebloom, you really care about your sister, Don'tcha? Well don't you worry one bit. I'm just going to fuck her. That's all! She'll like it a lot. As for you? I'm sure you'll get a real kick out of it". Pinkie really wasn't talking to anyone, they couldn't hear her. But she felt it built tension, at least for herself. Or perhaps that was anticipation.

With a gentle moan, Pinkie lifted herself from her chair as her sex left traces of her juices along her tail. She stood up straight, put away her clipboard, and pulled back her tail as she stepped out of the room and into a chrome hallway towards the first testing chamber. "Alrighty Sweetie Belle! Time to have some real fun!" Pinkie giggled as the massive metal door slowly opened just from her encroaching presence.

Upon the door opening, Sweetie Belle looked through her glass cage to see who was beyond it. At first, she was scared, but when she saw it was the long lost Pinkie Pie, she smiled and banged upon the glass. "Pinkie! Pinkie! You're ok! Did they capture you too? Please, you gotta help me! They took me and the others to this creepy place! They took our clothes and....wait". And that is when Sweetie Belle noticed Pinkie's loose lab coat and cheerful smirk. "P-Pinkie?" Sweetie Belle said with worry as her smile disappeared.

Pinkie herself just took a seat behind a desk, smiled, and looked at Sweetie Belle from the safety of the clear white chamber from the other side of the glass. The room from Pinkie's perspective had the door she came from, another door leading further into the facility, and of course, the glass chamber containing Sweetie Belle. "If you haven't already guessed. I was the one who had you brought here. Gee Sweetie Belle, I thought you'd be smarter than that!"

Sweetie Belle gasped, she still had trouble believing it despite seeing Pinkie pulling out papers from the desk to write notes on. "P-Pinkie..w-why? Why are you doing this?! We're your friends. We were worried about you!".

But Pinkie just shrugged as she pulled out a small gadget with a few buttons from underneath her coat. "Yeah I know. And I was worried about everypony too. Worried about the fact that at the end of the day, theirs usually so many moments where ponies frown and are sad. Welp, I'm here to fix that. And you're going to help me Sweetie Belle"

Sweetie Belle was frightened. More scared than she has ever been in her entire life. She shook as she took a single gulp, daring to ask a question which she felt the answer would mean something truly horrifying. "W-what do you mean? H-how am I going to help?".

Pinkie gave a light chuckle as she stood up and drew close to the glass. She bent forward and let her pink plump breasts hang down from her chest as she smirked and pointed right at Sweetie Belle. "By laughing of course. That's all I want. Is for you to laugh."
