A continuation of the Flutterbro sequence I got from atcpony earlier...

It was another happy-go-lucky day for Pinkie Pie. She was ready to bake away at Sugarcube Corner and work on her various party plans for the upcoming birthdays, celebrations, anniversaries, and so on and so forth in Ponyville. The pink pony had a full day ahead of her.

But strangely, she found in her little den something she had never seen before. It was a huge barbell. She certainly didn't own it, much less lift weights. She worked up enough of a sweat as is as she hopped and skipped from place to place. Sooooo, why was it there? It certainly made her think!

Though, it also made her curious. Could she actually lift that barbell? She never really tried before. Bulk Biceps made it look so easy! Maybe she could give it a whirl! It was right there after all. She can figure out who it belonged to later.

After just trying a little, Pinkie soon realized how tough it was. Trying to lift it nearly snapped her in two! It was so heavy for the curvy party pony! How anyone snuck it into her room was beyond her given that weight.

Most might've just given up there, but something didn't feel right to just quit. Whether it was a certain stubbornness in her or caused by the strange, magical aura wafting off the barbell and into her, she didn't care (or notice). She had to lift!

And so she tried and tried. Soon, she began to make some headway, first lifting it to her thighs and then to her neck. She trembled and quivered, her entire mind focused on this one task. As she did, her party frame ballooned into a buff frame. Curves vanished, replaced by muscle mass that would put stallions to shame. Her mane and tail deflated, the former shrinking into a ponytail and then a bun… a manly stud bun.

Pinkie didn't noticed a thing, excitement growing more and more. This? This was fun! The higher she raised it, the more she grew to love it. It became so easy after a while, something coursing through her. She felt strong, powerful, full of a vigor that she didn't know she had in her. It felt good to lift, maybe as good… or perhaps even better than throwing a party?

Then, with one big puff and gruff snort, she raised the barbell above her head. Her entire body throbbed and swelled, the last traces of her marehood fading away. Pure muscle took over, tearing and morphing her clothing into something more befitting. Her fur and tail deepened in color, new, scratchier body fur appearing on her face and body.

She… no, he felt great! Pinkie felt incredible! It was so darn good! He held the barbell up high with one arm while flexing the other. He is powerful, handsome, and all too excited by this! His body and being was different, but he didn't care. He loved the sexy stud he was.

Pinke… Bubble Berry felt so good that he started doing more deadlifts and pumping, working those new muscles and gains for all their worth. He occasionally took a break to admire himself in the mirror, flexing and posing. Wait until those babes he hung around with got a lot of him. Oh, they would love to eat him up!

An hour passed by the time he stopped. He was very much late for his shift in Sugarcube Corner. He couldn't let the Cakes down! Surely they would understand he had to do all of that lifting and posing. A bod as good as this needed to be worked on and appreciated. Maybe they would even let him just wear an apron only so pony customers could admire the new him.

Speaking of which, being worked on… perhaps after he finished his shift, he could hit the local gym and continue pumping iron. He needed to stay in shape after all! All that party planning could wait… or maybe he could think of new ideas. Perhaps workout and exercise parties are what Ponyville needed more of instead of ones where they shoved cake and calorie-heavy snacks down their pieholes. The town could do with a lot more buff, himbo, gym bro-esque stallions like him. That would really make everyone and Bubble Berry smile a lot.
