The Game of Estrus

Discord's laugh echoed throughout the auditorium. "Oh, the looks on your faces. I never get tired of the expressions you ponies can pull."

Twilight was the first to recover from the shock. "Discord!? How can it be...? You should still be imprisoned in stone at Canterlot!"

"Indeed I should, Twilight Sparkle." Discord glared at her. "Thanks to you and your friends, I was once again sentenced to the torturous punishment of doing absolutely nothing for millennia."

"But you escaped. How?"

Discord chuckled again. "Oh, Twilight, you are a hoot. Tell you what, since I know how much you love solving riddles, I'll let you figure that one out for yourself. Besides, aren't you more interested in hearing about the competition you'll be taking part in?"

Rarity spoke up. "Oh, please. Do you honestly believe we'll still take part in this contest, now we know that it's being hosted by a brute like you?"

"You say that as if you have a choice in the matter. Now that you have stepped into this room, you are all participants, whether you like it or not. However, if you wish to leave before hearing the rules, then be it on your own head." With a flash, Discord was behind them, opening the main door and gesturing that the ponies were free to leave.

Twilight frowned. "All right, Discord. What's your game this time?"

"I'm glad you asked!" Discord raised his arms, and a bright flash filled the room. Twilight felt her body tingle, and sensed a large amount of magic around her. When her vision returned, she saw that Discord had returned to the stage.

"The game can be summarised as thus," Discord said, pulling a blackboard out of nowhere, with the words "ELIMINATION BY IMPREGNATION" written on it.

"O-oh m-my..." Fluttershy managed to stammer out before fainting.

Pinkie squinted at the blackboard. "What's iii, imp-reg-nation? Is that like, a country that's regulated by a bunch of tiny demons?" She giggled to herself. "That sounds funny. They'd be bossing all the bigger demons around!"

"Ugh," winced Rarity, wrinkling her nose, "this sounds positively vulgar."

"Complain all you want, my little ponies, but know this. I have just made modifications to each of your bodies." Discord paused, relishing in the ponies' reactions. Twilight gulped, thinking back to the magical tingling she'd felt earlier. She glanced over herself, looking for changes, and noticed other ponies doing the same.

"Oh ho ho ho ho. You won't find the changes by looking, so let me just explain. I have added a total of two new features to each of you. Firstly, I have increased your fertility far beyond your normal levels, to the point where all it would take to impregnate you is for your nethers to come in contact with a single sperm. And secondly, I have introduced a strong hypnotism spell into your subconscious, which will activate itself the instant you are fertilised. Once activated, you will become enslaved for life to the stallion who knocked you up, having no choice but to obey his every command. So, any questions?"

"You're sick," Twilight muttered under her breath. She could see most of the ponies around her starting to freak out.

"That is not a question," Discord whispered into Twilight's ear, having appeared beside her. Twilight jumped, and backed away from him slowly, growling.

With a flash, Discord was on stage again. "Now, as I showed you, this is an elimination contest. You win by being the last one left after everypony else has lost." A thin book and a scroll materialised in front of each pony. "That book contains the full rules, and the scroll will help you keep track of who's left in the game. Good luck, every pony!" With another bright flash, he vanished.

Twilight was amazed the room didn't immediately descend into panicky chaos. Some ponies stood slack-jawed, unable to comprehend what had just happened. Others were nervous wrecks, curled up in the corner shivering. A few, Twilight was impressed to notice, were calmly flipping through the instructions, though they were still showing understandable concern. She opened her own book, and the others peered over her shoulder, including Fluttershy who'd been roused to her senses.

There are four ways to be eliminated from the game:
1. Being impregnated,
2. Telling a non-participant, directly or indirectly, any detail about the contest,
3. Travelling to, or attempting to contact anyone in Canterlot,
4. Death.

Breaking of rules 2 or 3 will result in severe punishment.

"What the hay!? Stay away from Canterlot? But that's where I live!" Twilight looked up, and saw a grey Earth pony in a bow tie glaring at her rulebook. A white unicorn with a vibrant blue mane put a hoof on the Earth pony's shoulder reassuringly. "It's cool Tavi, you can bunk with me 'til this thing blows over." Rule 3 concerned Twilight as well; how would she send her reports to the Princess? She glanced to the next page in the book.

Your scroll will automatically keep itself up-to-date with the status of each competitor, letting every player know when another has been eliminated. In addition, the colour of the square by each pony's name lets you know their sexual status, both at the start of the game and at present. Cyan represents a total virgin, yellow means some light sexual experiences, and pink means that they've had sex at some point.

As she read this, Twilight unrolled her scroll.

It did seem as if every pony present was listed here, along with a couple of squares by each of their names.

"Hey Rainbow." Applejack was indicating her own scroll with a hoof. "What's the meanin' of this here yellow square by your name? Y'all foolin' around with somepony behind your friends' backs?"

Rainbow tried to keep her cool demeanour, but Applejack noticed a faint blush on her cheeks. "Pshaw, what, that? That'll just be from back at Flight College. Gilda and I had a thing for a while during our last few years there. What I can't believe is you guys being all so innocent... well, I can probably believe it from Fluttershy and Twilight, but still."

Meanwhile, Pinkie Pie was rolling on the floor laughing, having just had the facts of life explained to her by Rarity. "Hee hee hee hee hee, s-so that's how babies are made? That's so silly!"

"Pinkie Pie, keep your voice down!" Rarity was blushing. "This isn't a very ladylike subject to be discussing."

Fluttershy was curled up in a ball, hiding her face behind her hair. She lifted her head slightly to glance up at Twilight. "T-Twilight... do-does this mean we-we'll... have to... g-go out and... and m-m-mate with somepony?"

Twilight tapped her own forehead with a hoof. "No... it means the exact opposite of that! Girls, don't you see? We've all kept our innocence 'til now, so why would that change any time soon? This game is completely harmless!"

Any joy gained from this revelation was short-lived, as Discord's laugh emanated from the walls again. "Oh, one last thing you should know... I'm currently hypnotising the stallions in the next room as well. Their libido is going up, and their morals are going down. Just so the game has a bit of challenge, you understand."

Applejack kicked a wall in anger. "That damn dirty Discord. He's tryin' tah turn honest ponies into criminals!"

Rarity shook her head in despair. "There weren't enough good stallions in this town as it was. Whatever will become of Ponyville now, if Discord has created a gang of wanton rapists?"

Rainbow took off into the air, flexing her muscles. "That does it! I'm going in there to give him a severe butt-kicking!"

Twilight caught her with her magic before she could fly out the door. "No, Rainbow! If you go in there now, you'll be surrounded by Discord's hypnotised stallions, and then who knows what'll happen to you!"

Rainbow dashed outside, and then back in through the other door leading into the building. Flying down the corridor, she came out into a large auditorium that mirrored the one she had just come from.

Gagging, she put a hoof over her mouth and nose. The room stank of body odour and musk. Every pony in the hall was staring up at the stage, where Discord seemed to have just finished casting his hypnotism spell.

"Ah, the lovely Miss Rainbow Dash." Discord grinned at her, a disconcerting glint in his eye. "Perfect timing. I was hoping I'd be able to give these boys a trial run."

"Oh yeah? Well I was thinking of giving my hooves a trial run, too. Right into you smug face!" Rainbow retorted, miming boxing motions.

She suddenly became acutely aware that every pony in the room was now staring at her. Their shafts were all out of their sheaths, and some of them were drooling.

She snorted. "Dream on boys. I bet I could take you all on myself!" Just then, an overly-muscular white pegasus leapt into the air and tackled her to the ground, pinning her down. "YEAH!"

Rainbow struggled in vain, and looked up at her captor, expecting him to force his way inside her and claim her at any second. Instead, he just kept her legs pinned down, until some other ponies came over and held each of her hooves individually. They lifted her off the ground, so the muscled monstrosity could lie down beneath her, before wrapping each of his legs around hers to hold her in place.

She kept struggling futilely in his grip. "Lemme go! Lemme go! Lemme- ahh!" She gasped as she felt something prodding at her asshole. "N-no way..." With a sudden thrust of his hips, her captor thrust his oversized cock inside her.

"AHHHHHH!" Rainbow screamed out in pain. She tried to rationalise that at least if it was her ass, he couldn't enslave her, but the pain was too great for her to think straight. "Pull it out, pull it out! Your dick's too bucking huge!" The macho stallion paid no heed, roughly thrusting in and out of her ass repeatedly.

With her eyes closed in pain, she didn't notice the other pony walking up to her until she felt the tip of his member poking its way into her other hole. She looked up in shock, and saw a young weedy-looking pony with buck teeth, large glasses and terrible acne standing over her. "No, wait... stop..." she begged, just as his shaft slipped inside her. Her hymen had been broken before, from a particularly rough session with Gilda, so he was able to slide in all the way up to his balls with no problem.

"Ohhh yeah," the younger stallion moaned, "it feels just as good as I'd imagined..." Rainbow struggled against the first stallion with renewed vigour. If she didn't do something soon, she'd be stuck obeying this pathetic egghead for the rest of her life.

"Ohh boy, I'm gonna cum!"

"What?!" Rainbow's eyes widened with fear. "No way, that's way too quick!" Nonetheless, she saw his face contort, as he prepared to fire his seed inside her, claiming her in the process. Rainbow tried everything she could to break free, but she knew it was too late. She felt regretful that she hadn't listened to her friends, that her own headstrongness was what had sealed her fate. She could only bite her lip, tears in her eyes, as she felt the first spurt of his cum inside her, and her free will melted away.

"Wow," panted the geeky stallion, withdrawing from her pussy, "that was amazing..."

Rainbow smiled up at him. "I'm glad you enjoyed it, master."

"Master, eh?" He rubbed his chin. "I like that. Hey, big guy. Get the hay out of my slave." The oversized pegasus reluctantly withdrew from her ass, which had been stretched much wider over the course of his brutal bucking. "Good. Now stand up, slave. We're going to have such fun together, playing chess and reading novels and bucking all day long."

"Do you have Daring Do, master? The last chapter I read ended on a cliffhanger."

"Daring Do?" He sneered. "That poorly written trite? No slave of mine is reading rubbish like that. Just presume she saved herself by some stupid contrived method like she always does, and forget about it."

Rainbow shuddered at the thought. "All right then Twilight, what should we do?"

Twilight considered their options. "...run."

"What? Run away!?" Rainbow was outraged. "Twilight, I know it's dangerous, but we can't just let Discord have his way with Ponyville like this!"

"We won't!" Twilight stamped her hoof. "We will defeat him. But we can't be reckless. Right now we need to get away before he unleashes those hot-to-trot stallions on us. Once I get back to the library, I can look into a way to get us out of this. So for now, you should all prioritise on staying safe." She turned and addressed the rest of the ponies gathered. "Listen up, everypony. You should all head on home right now, and I'd advise staying indoors as much as you can for the time being. I will be looking into a way to fix this whole mess, so just sit tight, and I'll get back to you."

The other ponies looked hesitant. One pony, who the list identified as Octavia, stepped forward to confront her. "How do we know we can trust you? This is a competition after all. You could just be in it for yourself."

A pink unicorn stepped up to place herself between Octavia and Twilight, facing up to the grey Earth pony. Twilight recognised her as Amethyst Star, the pony who'd lead the Animal Team during the Winter Wrap Up. "Are you crazy? If there's anyone we should be trusting, it's them!"

"Oh? And why's that?"

Amethyst looked the Earth pony over. "You're from Canterlot, right? Then I guess it's fair you don't know. The celebrations were only open to Ponyville citizens, and I think the newspapers were forbidden from reporting on it. Isn't that right, photo-girl?"

The journalist looked up from scribbling in her notepad. "Huh? Oh, right, that! Yeah, by order of the Princess no less. Never did get told why."

Octavia was looking severely confused. "What are you all talking about?"

Amethyst gestured towards Twilight and her friends. "Basically, these six, not including the zebra, are unsung national heroes. You've at least heard about the Nightmare Moon and Discord incidents, right? These ponies are the ones who saved the day on both those occasions."

"No way. You seriously expect me to believe that somepony would pull off a feat like that, and then just not tell anyone about it?"

"We had to," Twilight interjected. "If everypony had known, we'd have become celebrities, and I don't think Fluttershy could have handled that. Plus it'd have been a real bother for the rest of us too."

"For most of us, anyway," Rarity pointed out, applying a little extra make-up. "Not all of us are afraid of the bright lights of stardom." She then struck a pose and looked towards the photographer, who quickly took her picture before going back to writing in her notepad.

Amethyst nodded. "I'd say that if you still didn't believe it, then you should go and pay closer attention to some of the stained glass in Canterlot palace, but that's not really a viable option right now."

Octavia was still looking hesitant. "So only Ponyville ponies knew about it..." She furrowed her eyebrows. "Ponyville ponies knew about it, eh?" Slowly craning her neck around, she turned to glare at the pony snickering behind her. "Viiii-nyyyy-llll! Did you know about this?"

Vinyl clutched her stomach, and collapsed to the floor laughing. Octavia sighed, and looked back to Twilight. "Forgive me, I didn't know. I shall do as you ask."

Twilight nodded. "I understand. But now everypony, I strongly recommend you get away from here as fast as possible. Those stallions could be let loose at any second." Needing no more encouragement, everypony fled the hall in unison. Once outside, they all scattered in different directions, heading home as fast as possible. Twilight looked back, and noticed there was still a distinct lack of stallions emerging from the building. Was Discord trying to lull them into a false sense of security?

Twilight's group soon reached the town centre. Unsurprisingly, there was quite a large number of ponies gathered around, going about their business.

"We need to warn everypony," Rainbow realised. "Otherwise they'll be totally unprepared if they get attacked by stallions."

"But how?" Fluttershy asked worriedly. "The rules say we can't tell anyone about the contest."

Twilight tapped her chin thoughtfully. "Then we have no choice but to make something up. Sorry, Applejack."

Applejack shook her head. "I ain't fond of lying, but it's better than leavin' everypony in Ponyville defenceless."

They took a moment to discuss possible stories, before settling on one that wasn't too far from the truth, and should adequately warn everypony. All agreeing that it would sound most convincing coming from Zecora, the zebra situated herself in a spot where she could easily be seen. Twilight concentrated her magic into Zecora's voice, to make it heard across the square.

"Listen up you pony folk! What I have to say is not a joke.
If you do not stay to hear, then for your own safety I fear.
This news could truly not be worse. It seems some ponies have been cursed!
This curse is said to drive them mad, and make them do things oh so bad.
It may cause them to attack, so all of you should watch your back.
While we are trying out some cures, it would be wise to stay indoors.
And if a pony's acting strange, you'd best try to keep your range."

Most of the ponies had gathered around her by now. It looked like they'd understood Zecora's message, but were probably eager for details, which Twilight stepped up to provide.

"You heard her. A bunch of ponies, mainly stallions we believe, have been hit by a strange curse-like affliction. It's not really a curse, of course, because there's no such thing, but for now we can't say what's causing it. We're looking for a way to fix it, so until then, just be wary of any pony acting suspiciously, okay?" There was a general nodding of heads. "Okay, good. Please feel free to resume your business."

As the crowd disperses, the two of them rejoined the rest of the group. "We should probably head on home for now too," Twilight suggested. "Zecora, do you think you'll be safe enough at your place in the Everfree Forest?"

"I can set up many a charm, to keep away those who mean me harm."

"That's a relief. All right, the rest of you, just try being cautious around any pony you run into for a while." They all turned to head off their separate ways, when a thought struck Twilight. "Rarity, could I ask you a favour?"
