It was a sweltering day in Ponyville. As any hooved creature could tell, it was a good time to go to the gym in such a day like this. Everypony wanted to get the cool refrigerator like feeling of "Air Conditioning" in their faces. And the comforting exercise machines that were inside are a delight to use. Almost every notable resident Ponyville user was there and even some from out of town, and it truly was a day to remember.
It was just like any other gym day, but it seemed a new comer had arrived.
"As I was saying, Braeburn. I look at all these mares working down on those machines, and I can't even touch them, it sucks balls." said Soaring with a towel around his neck.
"I know bro, it's hard to just watch all those flanks shaking against the air like that... hey Soaring, what are you looking at?"
"Gagagagagaga, Uah uuat."
Braeburn looked at his compatriot foam in the mouth and sparkles in his eyes. He couldn't help himself from what he saw.
"Soaring!? Whats wron-"
And he turned and saw it.
A small donkey, walking towards the general Ponyville Gym with a gelatinous large ass. It shook in its folds, it flopped like newly made jello, and every stallion couldn't keep their eyes off it. The shadow of the awe inspiring, firm butt that everypony couldn't help but watch, even the mares, but in that regard in disdain.
"I need it, I FUCKING NEED IT." said Braeburn desperately.
"Oh celestia, If I could sleep on those ass cheeks like a beanie bag AOOOOOOOGH!" screamed Soaring with animalistic anger.
The small donkey walked to the doors with all the stallions glares at her. She opened through and somehow squeezed her massive ass through the double doors with a suction pop. She stepped on a treadmill and began running, her ass flopping up and down.
"My goodness, It's statistically impossible to have such a big ass, how did she do it!?" said Twilight Sparkle with an envious stare. She let loose the weights she was working with and let them drop to the floor.
"I'm going to talk to this missy, and maybe learn how she got that strong caboose."
Twilight Sparkle came up to Donkey Hotey, she watched the jiggling back bags cover up the entry way to the treadmill.
"Uh... excuse me mam, could I ask you something?" she asked.
Donkey Hotey stopped the thread mill and accidentally hit Twilight Sparkle to the wall with her ass muscles. It was so hard that the force caused her to make a hole to the shape of her figure. Getting out of the treadmill and seeing that no one was there, she returned to her workout with her big ass trailing behind her.
As she continued her workout, the stallions sat nearby to watch the pendulum like butt cheeks. They couldn't resist the allure of such a sleep-able fun bags.
"Oh man, she's the girl of my dreams." said Braeburn while trying his best to control his erection.
"Eyuuuuuup." said Big Macintosh with hearts in his eyes.
"I can't take it anymore! I'm coming for those loveable bags of pure passion!" said Soaring as he ripped off his workout clothes and leaped onto the ass like a bug to a bug zapper.
"I'm finally home! HOOOOOOME!!!"
With a tight grip on the bed sized butt, Donkey Hotey started feeling her precious cheeks being fondled.
"What the @$#&%!?" she said as she felt the manly presence on her.
Soon, more Stallions leaped onto her ginormous flesh, unable to control their love for Donkey Hotey.
"Get off! I'm not some slut you can butt uglies with! OH GOD THAT TICKLES."
The stallions then started sniffing and humping the big buttoon. Their erect cocks ready to satiate every female urge she had.
But, of course, she wouldn't allow that kind of shit on her butt.
With the force of Tartarus and Celestia, or something, she pushed against them into the wall, knocking them down the wall slowly.
"I am not a Donkey to be touched, you ravenous rancors!" she said with furvor.
And then they dogpiled her.
And they uncontrollably raped her, she screamed in agony as the male beasts plunged their male sticks into every hole they could get. She gagged several dicks, balls and even some clit because some mares were into that. It was a dogpile of sex and Donkey Hotey screaming and gagging.
Several hours later, she lay on the ground. Covered in fluids and her ass finally returning to normal.
She made a weakened reply, "Never going to the Everfree Forest again...". With those words, she went to sleep before coughing out a large sum of cum.
