Author's Notes:

This is an alternative epilogue to the previous one. Go with whichever of the two you prefer. If you really liked all the fetish fuel in the story, I'd suggest you go with the first epilogue. If you felt it was all too much (reflected in the high number of downvotes), go with this one. I had intended this to be set AFTER the first epilogue, but I figured that would ruin it for people who actually liked this story, and I don't want to do that.

Also, contains a bit of death, which I don't usually do, but it's kind of necessary and you'll see why.

10 years after Rainbow Dash and Cherry Fizzy's wedding, an evil unicorn of Equestria was plotting revenge.

Starlight Glimmer had been the dictator of a village where she forced everyone to have the same cutie mark. But Princess Twilight Sparkle and her friends had stopped her, caught her, and taken turns farting in her face, causing her to pass out. As they tried to decide what to do with her, she regained consciousness and ran away.

She had now discovered a time travel spell, which combined with her magic, she used to go back in time and change history. Twilight followed her, but Starlight froze her in crystal.

"You know, before I do this, I should do something else," said Starlight. She cast a spell that took the form of a blue light that engulfed all of Equestria. "There, now all ponies are much less gassy than before. No more than the humans, depending on what we eat. But that'll keep you from farting in my face in the future, if I am unsuccessful at preventing you from being born."

Twilight broke free of the crystal. "Where are we?"

"You mean when are we? We're over a thousand years ago! I tracked your ancestors born around this time! They haven't even met yet, and I will destroy them and erase you completely!"

Twilight and Starlight engaged in a battle of magic spells. When Twilight deflected one of Starlight's magic blasts, it hit and killed a butterfly.

"I can't beat her with my magic alone," said Starlight. "I have to go to the world where there is no magic. Whose inhabitants are no more gassy than us ponies are now."

Starlight sealed her magic inside a necklace, and ran. Twilight ran after her, because her wings had been injured in the fight. Starlight ran through the portal to the human world, and Twilight followed. Starlight continued to run on all fours, and then deliberately slowed down, allowing Twilight to catch her.

"I got you, Starlight! You will not hurt my ancestors! Now take me back to my time!"

"No," said Starlight. "If I can't erase you, then this is the next best thing!" Starlight touched the gem on her necklace, which started to glow.

"Starlight, what are you-"

KABOOM!

Twilight and Starlight vanished in a massive nuclear blast. The only other casualty of the explosion was a butterfly - the counterpart of the Equestrian butterfly they had killed.

...

As a result of the butterflies' deaths, history in both worlds was changed drastically. In addition to ponies not being as gassy anymore (much to Celestia's disappointment), the sirens came to Equestria earlier from a distant land, prompting a unicorn named Stygian to gather some ponies together, who banished the sirens to the human world. Unlike in the original timeline, they retained pendants allowing them to use a bit of their power, and they adjusted to human life rather quickly, including the need to urinate, and never once wet their pants, although they did fart occasionally, because who doesn't?

Sunset Shimmer turned cruel and dishonest and became the school bully in the human world. Twilight still became friends with Applejack, Rainbow Dash, Rarity, Fluttershy, and Pinkie Pie, except that when she got her cutie mark, she hatched a dragon egg, and the dragon, Spike, became her assistant. They still had to deal with enemies like Nightmare Moon, Discord, Queen Chrysalis, King Sombra, Tirek, Starlight, Stygian, the Storm King, and Cozy Glow, which unfolded slightly differently than before without opening dimensional rifts, and Twilight still became a princess.

Starlight's time travel happened earlier, and to the time when Twilight was a filly, in which she attempted to stop the event leading to Twilight and her friends getting their cutie marks, and Twilight was able to reform Starlight and prevent her from changing history a second time. Twilight and Starlight were therefore spared from their explosive fate, though their alternate selves' fight a thousand years ago was preserved to prevent a paradox.

In the human world, Rainbow Dash, Applejack, Indigo Zap, and Sunny Flare washed as often as humans regularly did, Pinkie and Sonata never wet themselves from laughing at farts, Fluttershy never wet herself after getting out of diapers, having a bladder no smaller or weaker than the average human, and Indigo, Sunny, and Wallflower didn't wet themselves either. Twilight also never wet herself even while studying, and Cherry Fizzy was never born in the human world. Thus, there was no fetish fuel to rub off on the others, aside from occasional non-sexual buttplay, like Pinkie Pie and Fluttershy doing a rump bump, or Applejack kicking Rarity in the butt. Crystal Prep also never did farting contests, and Rarity never got to the point where she wet the bed.

Rainbow Dash, Rarity, Pinkie Pie, Fluttershy, and Applejack became friends around the same time, until Sunset Shimmer broke apart their friendship, and when Princess Twilight arrived from Equestria in pursuit of Sunset, she got them back together and they reformed Sunset. Sunset had brought magic into Equestria, causing the sirens to become a threat, until Twilight, Sunset, and the other girls destroyed their pendants, leaving them as harmless teenage girls. Then they met EqG Twilight (who now had a dog named Spike, counterpart of the dragon) while competing with the Shadowbolts, and had more adventures after that, including Wallflower temporarily erasing the girls' memories of Sunset as revenge for making her feel invisible, and later becoming friends with Sunset.

It was as if the fetish fuel never happened. Which, it didn't. All their fetish fuel, all the wettings, excessive farts, and the stench of the smelly girls, was erased from history for all eternity.
