“‘Become a better you! More confidant! Stronger Pride! Guaranteed or your money back!’ Oh my… that does sound lovely,” Fluttershy’s soft index finger tapped the page long advertisement on her magazine. It was colorful and alluring, though a sixth of the page, a corner, was dedicated to a strong grey minotaur. Despite having troubles with Iron Will before, Fluttershy was more attracted to the flashy commercial page. Rarity had warned her many, many, times about capitulating to these wonderful advertisements. But the promises that the paper offered was too much for her and within the hour Fluttershy had ordered a single box.
 
A few weeks later there was a loud knock at the door. Fluttershy opened the door just a crack to peek at her visitor. Instead of seeing a friend, her door was pushed open by an avalanche of boxes. They washed over the yellow pegasus throwing the door wide open. She was uninjured but certainly astonished. She picked herself up and was greeted by a clipboard and pen. Derpy Hoove’s voice broke through the wall of cardboard.
 
“Sign here please,” She asked, Fluttershy complied scribbling her name on the dotted line. The moment she finished they were yanked from her hand, making her long pink mane follow the sudden current.
 
“Have a nice day!” Derpy commented then flew off.
 
“W-wait!? W-why are there so many!?” Fluttershy cried but it was too late. She huffed, putting her hands on her hips and looked over the mess of boxes.
 
 
It took Fluttershy a good few hours to move all the boxes inside. The walls of her cozy cottage were filled with crates, it was like her living room was a warehouse for Iron Will. Fluttershy had wondered how Derpy had managed to deliver all these boxes without a cart, she was a strange mare and it was best not to think about it. Then her mind wandered, questioning why there were so many to begin with! At last, Fluttershy unfolded the large letter that came with the delivery. It was an intimidating poster sized instruction ‘manual’ based in a comic style with Iron Will himself explaining the process of use. Fluttershy’s eyes scanned it once over, then read it a second time in confusion.
 
“Undress…? That’s step one…? Then brace for step two…? Only two steps?” Fluttershy’s tone was perplexed, her lips twisted to form a puzzled half smile. She complied hesitantly, putting her green sweater and navy skirt into her closet. Her soft white lingerie was placed over a couch and she opened one of the boxes. Inside was a silver can with dart green stripes travelling down its side. After a little investigating Fluttershy found a small label on the bottom, ‘Changeling Cola.’
 
Fluttershy took a deep breath, step two. She then pushed the tab down on the soft aluminum top, there was no escape of carbonation. With only a moment of hesitation she put the rim to her lips and took a sip. The next few seconds were simply a blur to her. Her body felt warm, hot then almost burning! It wasn’t a unpleasant burning, simply pleasurable hot flash.
 
 
The drink worked its magic and now Fluttershy’s G cups were no more. Instead, laying before her, was two wagon sized yellow heaps of breast flesh. Her nipples trembled slightly, pushing against the wooden floor. Despite her sudden growth Fluttershy didn’t feel any different, no extra pride no extra confidence. There was nothing but gargantuan breasts. Fluttershy’s gaze looked at the rest of the boxes. Was all the extras a gift? Or was it something more? Had someone ordered for her or was she to be the prime example of this ‘Changeling Cola’ endorsed by Iron Will? She sighed deeply and scanned the area behind her.
 
‘One sip and this much? Oh dear…’
