Ponyville Town Hall was packed to the rafters (literally for the pegasi) with all eyes focused on the stage, and the Mayor that stood ready to speak.

“Fillies and Gentlecolts, Citizens of Ponyville. Tomorrow we face once again one of our greatest challenges.” A hush fell over crowd. “We have survived Nightmare Moon, Parasprites, Discord, giant dragons twice, Nightmare Rarity, flocks of paparazzi foals...but this is a threat unlike any of them!”

The crowd looked over to the other side of the stage nervously, to the object they all feared.

“Hi Everypony” Pinkie beamed back and waved a hoof excitedly from the chair she was sat in, oblivious to the terror in the eyes of the ponies.

The mayor coughed to grab everypony’s attention again “Yes fellow citizens…Pinkie Pie is about to go on heat!”

As the crowd gasped, a louder voice called out “Isn't this exciting? Are you excited cause I'm excited I've never been so excited, well, quiet literally I’ve never been ‘excited’ before but I mean really, how can I not be excited at getting excited?” Pinkie sang as she randomly popped up next to various ponies in the crowd, before ending up where she started on the stage.

As the ponies realised just how Pinkie’s energy focused on a single goal could impact on all of them, a stereotypical pony called out “The Horror, the horror” from the crowd, and the rest all started rabble-ing.

“Can’t we use magic to stop this from happening?” Cheerilee called out “Won’t somepony think of the foals!”

“Citizens, we had asked if there was any magic that could be used to assist us, but Princess Twilight Sparkle will explain this is not an option.”

Twilight took the stage causing the Mayor to bow, although everypony else just noticed the onion horseshoe stuck to her muzzle “Hi everypony. You see, it was established…”

Twilight began her rant but in the crowd Lyra turned to her marefriend in surprise “Wait, Princess Twilight Sparkle is our Twilight Sparkle, from Ponyville?”

Bon Bon turned back to Lyra with an incredulous look “You didn’t know that?” the mare replied in shock “Where have you been for the past 14 weeks?”

“Around…just not to the library…I seem to remember spending a lot of time in my mistresses bedroom satisfying her every need!” the light green unicorn replied with a smile.

“Huh, fair enough” Bon Bon smiled back and the pair started making out to the delight of the stallions behind watching.

Back on the stage, Twilight was ending her lecture “…and only once Starswirl totally save the day as usual…“ Twilight sighed like a fangirl “…did Princess Luna and all other unicorns realise that using magic to suppress bodily functions is a bad idea.”

“Thanks for the detailed and not-so-whatever disturbing analysis there Twilight” Applejack took to the stage, stifling the urge to be sick “But don’t worry citizens, we are going to do everything we can to resolve this matter. But we thought it would be best to warn you in advance.”

After the meeting was concluded, Pinkie Pie and her friends headed outside and had a picnic on the big hill in Ponyville Park.

“Should I be insulted at everypony’s reaction” Pinkie Pie suddenly asked “I mean, I’m just a mare going into heat?”

“I don’t know Pinkie, do you feel insulted?” Fluttershy replied.

“Actually, not really, I just felt I should be. Although, it does feel a little weird for a whole town to be focused on my marehood!”

Spike blushed and Rarity did a spit-take “Pinkie please, have some decorum, and there are youngsters present!” she cuddled her drake-friend as she spoke

“Don’t give me that, he’s been ploughing your furrow for months now…” Pinkie replied with a wink, before putting her hooves over her mouth. Rarity and Spike were blushing intensively, whilst Twilight didn’t know where to look “I’m sorry, I don’t know why I said that. It’s just, everything relating to sexy times seems to be popping up into my brain a lot more today!”

Twilight turned to her friends and added ominously “It begins…”

The next morning Pinkie Pie woke up in her bed. As soon as she moved, she heard a ringing sound and looking down she noticed a collar around a neck

“Oh a bell!” she squeed excitedly. Her five closest friends who had slept over in her room stirred at the sound, and Pinkie started bopping her head up a down quickly to cause a constant ringing.

After a few moments, Pinkie noticed her friends were finally awake and starting bouncing around them. “A bell on a collar? Am I a cow now, are you going to milk me?” Pinkie turned and batted her eyelids at her farmer friend, shaking her hips suggestively.

“No pinkie, we just wanted to make sure you didn’t wake up and leave without us knowing about it!” Applejack replied, ignoring the mares enticing hip movements

“Sooo….no milking then?” Pinkies ears fell in disapointment

“No just no…and I guess that answers how you’re feeling” Twilight walked towards her friend.

“A bell was an ingenious idea, but you could have just tied me up or something. You know, tied me really tight so I couldn’t move at all. Maybe have to muzzle me to silence my complaints. And then because you would feel pity for me, you would let stallions up her to keep me company” and she nudged Rarity in the side.

“Darling, why would you ever…”

But Pinkie was on a roll and ignored her friend “And I would just lie there in bliss as pony after pony pleasured me! The gag keeping my screams of passion silent, the ropes keeping my body completely available to as stallion and mare alike…Rainbow, do you have wingboner?”

Rainbow tried to push down or fold her wings as the Pink Party Ponys attention flicked to her, but it was no use. “So does Twilight!” she blurted in panicked response, the alicorn equally trying to control her wings.

“Hey, mine are new, you’ve had years to practise some control!”

“Oh My” Fluttershy added, hiding her blushing face but unable to hide the appendages fully taut on her back.

Pinkie started rummaging through her cloest “You know, I have rope around her somewhere…for rope emergencies!”

“No!” her five friends called out.

Applejack came over to her oldest friend “Look Pinkie, we just want to keep an eye on you today, make sure you don’t get into trouble. We’re not going to be tying any pony up!”

“Awwwww, okie dokie loki.” And with that Pinkie made her way towards the door

“Really, we’re going to let her leave?” Applejack asked as they followed the Pink pony out of the room.

“We can’t force her to stay in here all day, it’s not like she’s broken any laws.” Twilight replied

“Yet!” was Rarity’s only reply

“What do you mean by that?” Fluttershy asked.

“All I mean is the day is young…” the unicorn grimaced “…and Pinkie can always fit a lot into the day."

Pinkie was bouncing down the street as she always did, and everypony waved and smiled at her as usual. But they also kept a little more distance between them

Pinkie came across the mayor and part of her entourage, and noticed the single stallion amongst the mares. Without a second thought, and with a speed of movement usually only seen by electrons during Quantum Leaps, Pinkie stood on top on the stallion,looking down into his upside down face.

“So, Time Turner, or should I call you Dr Whooves…or sexy?”

“Ermm” the brown pony replied, trying to back off, but of course with Pinkie standing ontop of him she moved in sync.

“Fancy giving my sonic a bit of a screwdriver?” Pinkie wink and swished her tail about the haunches of the stallion.

“Mmmmm, no thanks!” Time turner muttered. He wanted to get away from the pink menace with her pink menace, but was too polite to shake her off his back.”

“Awww, why not. I’m much tighter on the inside than I am on the outside!”

Pinkie found herself being lifted up by Twilights Aura and placed back on the ground, freeing Time Turner to gallop-free away.

Rarity picked up a newspaper in her Aura, rolled it up and tapped Pinkie on the head with it “Bad Pinkie, no touching random stallions!”

“Besides – “Fluttershy added softly “- he’s in relationship with Derpy”

“He is? Shoot, no wonder he wasn't interested” Pinkie sighed, before perking up “Oh, So I now get throw him a new relationship party…after I get a good bucking!”

Having scared half of the stallions in Ponyville, and annoyed most of their maref-riends in the process, the mane six was walking through the everfree forest.

“Has anypony noticed that there is a lot more mares than stallions around Ponyville, whats a pony got to do to get laid?” Four of the other mares looked at each other a little shyly, not yet having found a colt-friend in Ponyville

Pinkie picked up that she had made her friends slightly sad “Awww, don’t worry girls, I don’t think we’ve got anything to worry about. I mean Twilights got that sexy nerd thing going on, especially if she was to dress in that school-filly outfit she has!”

“Pinkie…I…that outfits just…” Twilight trotted ahead to hide her blush.

“Rarity is drop dead gorgeous, and knows it! Even if she grows tired of Spikes long tongue she wouldn’t be single for long.”

“Thanks darling, I think”

“Applejacks got a buff body anypony would die for…and a sass that I know the stallions love. Plus, so much stamina that she’s be able to go all night!” The farmer pony’s face went as red as the apples on her flank.

“Fluttershy has a natural beauty and shyness that stallions adore…and like most shy ponies is probably a dynamite in the boudoir!”

“Pinkie…I…” Fluttershy collapsed with embarrassment, Twilight carrying her along in her aura.

“And Rainbow Dash is so awesome she can get laid in ten second flat!”

“I am awesome!” Rainbow added.

“But no pony wants to date a stupid fat earth pony like me!”

“Aww…Pinkie, that’s…wait…you’re just trying to get some symathy sex aren’t you?” Twilight responded.

“Oh Twilight, you are a smart cookie…a smart sexy moist cookie...”

Rarity picked up a small stick from the side of the path in her Aura and tapped Pinkie on the head with it “Bad Pinkie, no hitting on your friends!”

“Sorry Rarity….Sorry Twilight…shame those vines that grabbed you and the other princesses aren’t about, they would keep me entertained for a while, squirming all over my helpless body.”

Twilight started to blush and Rainbow Dash noticed “Oh, wait a minute, they did that didn't they?” the pegasus teased the alicorn.

Twilight tried to keep her composure “I don’t think so, but I was only caught for a very brief moment!”

“But you have thought about it haven’t you, when you’re alone with Mr Snuggles.”

“How…how did you know?” Twilight blushed so hard that her face seemed to be giving off more light than her horn.

“Pinkie sense, it seems to be tuned into these things at the moment.”

“Twilight darling, how kinky of you!” Rarity teased.

“Just like how you wonder what a threesome with Spike and Applejack would be?”

“What?” Rarity and the earth pony gasped in unison, with now Rarity blushing.

Applejack raised her eyebrows and started walking next to the unicorn “Oh sugarcube, you only had to ask”

“Don’t joke about such things!”

“How do you know I’m joking?” Applejack replied in a sultry tone.

As Rarity huffed and turned away, Rainbow Dash noticed Applejack winking at her, and decided to join in “Hey, I want in on that hot action as well! Spike deserves all the mares afteralll…”

“Ladies please, whilst it’s good fun to tease Rarity, look what it’s doing to poor Pinkie” Fluttershy squeaked. Pinkie had a line of drool from her mouth trailing along the floor, the sort she usually only had thinking about creamy frosting.

“Sorry Pinkie!” they all replied in unison as their destination came into view.

Zecora started studying Pinkie as she bounced around the room

Twilight let out a sigh “But Zecora, you always have something to help us out, isn’t there anything you can do for her?”

Wait, did I just rhyme?”

Zecora looked over to the ponies with a slight look of smugness

“Well, this has been a bust” Rainbow huffed

Fluttershy hovered next to her friend and put a hoof on her shoulder “Although the trip here and back has wasted plenty of time, and got Pinkie away from town”

Pinkie was continuing her bouncing around the hut “Hey Zecora, what Black, White and Pink, and hotter than the midday sun?”

Pinkie sauntered up to the stripped animal and run a hoof through the zebra's mohawk "Why, the two of us making out silly!"

Zecora took a few steps back

“Awww, that’s too bad. I’m sure you know your way around a lithe young body like mine!” Pinkie fluttered her eyelids in the Zebra’s face, who remain unmoved. “Oh nevermind, back to town we go!”

“THANKS for your time Zecora” Rarity spoke over the end of that rhyme, much to the Zebra’s annoyance. Zecroa looked at Rarity, and a smile formed on her face.

“Okay we get it, time to go now!” Rarity interrupted again as Twilight picked up Fluttershy who had fainted again.

“…Bye Zecora!” Twilight called out leaving the Zebra to pick up her rhyming dictionary and frown at the poor choices available.

Outside the hut Pinkie was bouncing around even more than usual, and her friends looked at each other with worry. “Poor Pinkie, she needs an outlet for all this energy!” Applejack tried to reign in the party pony, with little luck.

“Wait, I’ve got the perfect solution!” Twilight clapped her hooves in glee “Why didn’t I think of it before?”

Twilight and the gang walked into the entrance of the cave, and instantly the smell of cotton candy mixed with sweat filled their nostrils.

“Trapping Pinkie Pie in the mirror cave was an awesome idea Twilight” Rainbow Dash admitted as they made there way down the slope into the main chamber. There were probably close to a hundred Pinkie Pie’s dotted around the cave, all napping. Most were still cuddled up to at least another, usually more, Pinkies, and all were beaming with the sweet after-glow of satisfying sex.

They looked around and found the pony with the bell collar still on. “I’m glad I knew a way to prevent this from being duplicated” Twilight spoke to herself “The risk of sending the wrong Pinkie back into the pond would be too great otherwise but best make sure” Twilight let out a loud whistle to wake all the pinkies up. “Pinkie, what is the password?” she shouted out.

Whilst all the other ponies around her just muttered rude words, the one they hoped was their Pinkie replied “Chimi-Cherry-Chonga!” with a content sigh.

Happy that they had the right pony, Twilight dispelled the others and the toys she had also left in the cave, not noticing that Applejack had hidden one she found particularly interesting under her hat. Twilight lifted the tired pony onto the farm pony’s back and the six of them left the mirror cave and went back to town.

“Pinkie, what was it like with…you know…loads of you?” Rarity asked, much to the surprise of her friends “What? I may be a lady, but tell me you’re not as interested”, a truth resulting in all of her friends nodding in agreement.

“Totally indescribably hot…so much so I won’t even try!”

Author's Notes:

Sorry for the delay in getting this story moving again, I have a few chapter ideas to build up to the climax.

Writing Zecora was a lot of fun...
