What's in the Box?

"Spike!" shouted a voice. "Wake up!"

"BWAH!" Spike jumped awake in a start. "Twilight? What time is it?" he said as he groggily rubbed his eyes and stepped out into the main area of the library.

"Just get down here now, we have plenty of research to do!" Twilight said as she frantically raced from one end of the library to the other.

"Research? Researching for what?" Spike said as he walked down the steps.

"The box!" she gasped. "I need to open it!"

"The 'box'? You mean that thing you found at the tree of friendship?"

"Harmony!" she corrected him.

"Right, right, harmony. It has literally been less than a week and you want to open it?" he smirked. "What happened to waiting until the timing is right?"

Spike had lost count of how many times Twilight went back and forth from one end of the library to the other. If she kept this up any longer she just wear another hole in the floor.

"You know what they say, curiosity killed the cat." Spike stated.

"Yes, but satisfaction brought it back." she retorted.

"But the cat's dead." Spike put it bluntly.

"That's not the point! Jus- Just help me find a book." she huffed. Spike walked over to a nearby shelf and lifted several books out.

"What are we looking for exactly?" Spike enquired.

"Anything related to the tree of harmony, so take out any medieval related book; I bet we'll find a good source of information starting there." Twilight said excitedly.

"The tree huh? Well, why not just read this?" Spike held up a book titled 'Star Swirl's Journal'.

"Where did you get this?" Twilight gasped.

"We got it from Canterlot. Princess Celestia sent all his journals over to this library just before your coronation." Spike said. "This one mentions a tree he found. It must be the tree of harmony."

"Spike! Why didn't you bring this to my attention?" Twilight grabbed the book using her magic and teleported over to her personal reading podium. As quick as she could, she shuffled through the pages, scanning ever single one for any mention of the tree.

"I just did." Spike huffed and walked to her.

"Ah ha! Here it is," she exclaimed. "entry number forty two." Spike peered over her shoulder and read along with her.

Entry 42.

Another day of failed attempts have resulted in this blasted box remaining sealed. The spell I've tried using is showing some results but there are six key holes, I can't manage any more than 4 spells simultaneously. My apprentice Clover has had no results either. She tells me of a tree that can open the infernal thing without unicorn magic. I hardly believed it at first, but tomorrow we will travel to the tree and hope for some answers.

"He never opened it." Twilight frowned.

"Well dang it, what do we do now?" Spike asked.

Twilight laughed to herself and shut the book. "Isn't it obvious?" she said.

"Uh- is it?" Spike said dumbly.

"There's six keys. Think about it, Pinkie Pie, Fluttershy, Applejack, Rainbow Dash, Rarity and myself. Six friends!" Twilight teleported to the other side of the library and threw another two books at her assistant. "It's almost as it was made for us. Imagine if the six of us had to go on six different adventures and learn a lesson about friendship to obtain a key?"

"So you're taking a shortcut." Spike said

"Yes." Twilight puffed out her chest and flared her horn.

***

A few hours later, all five of Twilight Sparkle's friends had gathered in the Golden Oaks library. Fluttershy and Rainbow Dash followed Spike to the library after listening to his huffed and puffed explanation, while Twilight sought out her other friends. Applejack and Rarity followed Twilight and agreed to help look for Pinkie Pie, and as if by some twisted fate, Pinkie Pie showed up at the library before they had a chance to set out and look for her.

"Thank you girls for coming on such short notice, I'm guessing you have many questions as to why I have called you here."

"Not really, Spike filled me in on the way here." Rainbow said.

"NOT ME!" Pinkie said as she bounced around in a circle.

"Well, anyway, I'm going to cast a spell listed here in Star Swirl's journal." Twilight saw Applejack and Rarity glance at each other with an uneasy face. "I don't want any of you to worry, but I have no idea what it might do. All I know is that the six of us have to do it together, as friends."

"We trust you Twilight." Applejack said, Twilight looked to every one of her friends faces and was returned with a smile.

"Spike bring me the book!" Twilight commanded.

No answer.

"Spike?" Twilight walked over him, he was reading the book with Star Swirl's spell. "Spike, I need the book to start the spell."

"Hang on Twilight," he flipped another page and read for a moment. "hey, did you know Star Swirl had four daughter's with his apprentice Clover The Clever. How about tha-hey!" Twilight snatched up the book from his little claws. "I was reading that!" he complained and huffed a small flame before storming off. "Fine, just try not to burn down the library, again."

"Uh- again?" Applejack asked as she looked at Twilight.

"I was mostly his fault!" Twilight raised her voice as if talking directly to Spike and nopony else. "Ok, here we go."

The six of them stood on each side of the locked box. Twilight flared her horn, all of her friends closed their eyes and concentrated of the friendship they shared, except for Pinkie Pie, who thought of cake frosting and kinky thoughts of licking it off her good friend Rainbow Dash. "Pinkie, please concentrate on someth- anything else." Twilight said as her horn grew brighter.

"Oops... sorry." she giggled.

Bright light glowed inside each keyhole of the box, the spell was working and Twilight could feel it. All of them could, as if they had a connected mind. Suddenly they all felt an intense pain between their hind legs, Twilight and her friends never expected pain like this, but they pushed though it.

"Ahhhhh!" The six of them screamed in unison.

"Just a little bit longer, I can feel it!" Twilight screamed.

A few moments later, the six of them collapsed in place. The pain quickly subsided and rendered each of them a little light headed, Twilight quickly stood up and examined the box. Each of the keyhole's changed shape and glowed with a bright white light. "We did it girls!" Twilight smiled with glee.

"AHHHHH!" A scream filled the room, it was Rarity's voice.

Twilight turned away from the box. "Rarity? What's wrong?"

"This is what's wrong!" she pointed to the black towering pole between her legs, swaying from side to side. "I have become deformed!"

"Bahahahahahahaha!" Rainbow Dash rolled over, pounding her fore hooves against the ground. "Ahahahahaha! This is too good!" she wiped a tear from her eye and rolled over again, feeling something prodding her belly. "Wait a second... AHHH! Twilight! What did you do to us?" A long black phallus also hung between Rainbow's legs.

"OOH! ME TOO!" Pinkie bounced around, stopping in front of Twilight and grasping her own schlong with her pink hooves. "What are they for Twilight?" Fluttershy chimed in with her own yellow and brown splotched cock swinging between her legs. "You too?" Twilight gasped.

"WEEE!" Pinkie continued to swing her black cock from side to side, effectively cock slapping Twilight in the process.

"Pinkie! Please! Stop that, it's disgusting!" Twilight gagged and tried not to vomit as the pink pony bounced off again. "Ok, all of you remain calm. I'm sure there's a logical explanation for this."

"Ouch!" Pinkie Pie cried as she crashed into the unopened box that remained in the middle of the library.

"Pinkie?" Applejack trotted over to the trapped pony. "What the- how in the name of apples?" Somehow, Pinkie had managed to fall, penis first, into a keyhole of the locked box. "Uh... girls, ah' think we got a problem."

In less than a second Rainbow dropped to the floor and laughed loudly. Haha... she's... hahaha... stuck... Haha... some... haha... p-pony hahaha!"

"Rainbow! This is nothing to laugh about!" Rarity scolded.

"Hey this feels good." Pinkie pushed her hips slightly, the light in each keyhole grew brighter each time she trusted. "Ooh, tingly."

Then it hit her.

"Pinkie Pie! You're a genius!" Twilight shouted as she approached a keyhole opposite her. "Everypony, gather around each keyhole." Twilight gently inserted her own purple horse-cock into an open keyhole.

It was a perfect fit.

"Twilight, you cannot be serious. We'll all be stuck." Rarity said.

"No we won't, we are the keys!" Twilight replied.

"SWEET!" Rainbow Dash, with renewed vigour, zipped over to an available keyhole on Pinkie Pie's left side and inserted her phallus into the glowing hole. "Ooh, that does feel nice. Dang, stallions have it good, this feels amazing." she said as she trusted harder and faster.

"Fine ah' guess, for the sake of friendship." Applejack inserted her orange stallionhood into the empty keyhole on Pinkie Pie's right side. "Oh my, wallop my wither's. This feels as snug as a bug." Applejack continued to thrust into the keyhole.

"It really feels so divine?" Rarity looked at the faces of her friends, she could tell they were receiving possibly the best pleasure she could imagine. "Ok! For my friends!" she said and thrusted her black phallus into the open keyhole between Applejack and Twilight. "Oh good heavens! This really does feel lovely." All five of them picked up speed, they all felt the tingling sensation in their newly acquired gear.

"Fluttershy please -huff- you're the last key, you need to- Ahh! -help us open it." Twilight called out in ecstasy.

"Um... ok, I guess it would't hurt." she approached the last open keyhole between Rainbow and Twilight.

"Don't -Mmm- hesitate, just go with it." Rainbow said.

"Alright." Fluttershy penetrated the last open keyhole and was rewarded with a pleasuring warmth that spread through her body, now all six mares were thrusting in and out of every keyhole, fucking it relentlessly in an effort to unlock the secret's hidden within. "Oh my... this is wonderful." Fluttershy mewed as she and her five friends continued thrusting.

"I feel -Ahh- tingly again." Pinkie Pie huffed.

"Ok girls -Mmm- I think we are almost there." Twilight moaned.

Then it hit them.

"AAAHHH!!!" All six cried out in unison as they orgasmed at the same time, each of them scrunched up their face's as they felt the warm liquid shooting forth from their stallionhoods inside the closed box. Their cocks were released from the grip of the box, small spurts of cum still shot from their cocks as the six of them collapsed on the floor of the library. The room lit up as the box glowed bright and brighter, everypony shielded their eyes from the blinding light, the six of them could feel the same tingling sensation from when Twilight first cast the spell. A moment passed before a cheery voice spoke up.

"I'm free!" a voice called, the six mares opened their eyes to see what they had just released from the box. It was a grey pegasus with a blonde mane, the bubbly cutie mark was very familiar to the six of them.

"Derpy?!" They shouted in unison.

"How did you get inside this box?" Twilight pointed to the opened box, each of the six sides opened up creating a flower shape on the floor.

"I got lost on my way to Whinnypeg." she stretched her hooves as she yawned. "But I did get some really tasty milk."

"Sweetheart, that wasn't-"

"Rarity, no. Just let her believe." Rainbow said as she place a hoof on her white friends shoulder.
