Background Pony #6BD5

“Holy tits!” Sunset shouted as her bra snapped off, letting her new G-cups slosh free.



“What did I tell you?” Trixie smirked, cupping her massive teats and giving them a jiggle, “Bolero's Bountiful Beauty is just one of the spells I've learned!”



A human doing magic. A normal, non-Mirror Magic'd human. Sunset wouldn't have believed it, if her tits weren't the size of beach balls. When Trixie asked if she could demonstrate a spell to 'increase her feminine attributes', she expected some sort of slight-of-hand trick involving makeup, or maybe one of those self-inflating bras. But the proof was in the firm, jiggling flesh hanging from her chest. She wrapped her hands around her new rack to cover her nipples, as Trixie reached into her bag and pulled out an ancient-looking tome.



“There are many more spells where this came from,” Trixie said giddily, flipping through pages with the eagerness of a child promised candy, “I know one that'll really knock your socks off!”



“Breast expansion, done that,” The amateur spellcaster continued, “How about butts?”



“Uh, Trixie,” Sunset began, reaching tentatively for the book, “Maybe you ought to let me take a look at-”



Before she could do anything, Trixie began to speak, her tongue twisting to pronounce words never meant to be uttered by a human tongue. Sunset made a move to lunge and grab the book, but was stopped as her legs suddenly locked up. Grabbing ahold of a nearby locker to keep from falling, she groaned as her ass began to swell inside her jeans.



She groaned as the rear seam popped open, revealing her bright red panties to the world. Her hips cracked and grew slightly wider, and she felt a pressure on her waist as if her belt were threatening to cut her in half. Scrambling to unbuckle it, she glanced over at Trixie just in time to see the blue-haired girl's skirt rip down the seams, fluttering to the floor in two pieces.



It wouldn't be quite so simple for Sunset; She bent over, desperately tugging her jeans down over her thickening thighs, but it was slow going, and within moments, she heard a sickening rip as her underwear exploded, letting her ass wobble free. It was big enough to fill a school seat – Any bigger, and she'd have problems trying to fit in a regular chair.



Thinking quickly, she ripped the book from Trixie's hands, the magician being too busy playing with her teats to protest. She tugged a lighter from her increasingly tight pockets, a beautifully engraved zippo that was a gift from one of her exes, and turned the book into a bonfire. It was a tragedy, watching some ancient wizard's life's work go up in flames, but… Wait, no, it actually wasn't. Fucking perverted mages.



The expansion slowed to a halt, and Sunset and Trixie sunk to the floor, breathing heavily. Each one had breasts bigger than their head and hips wider than their shoulders, supporting asses big enough to smother unwary pedestrians.



“Dangit,” Trixie groaned, looking at the destroyed book, “I flipped burgers for a month to afford that!”



Sunset opened her mouth to reply, but stopped, glancing up at the clock. 2:15 – Class change.



The bell rang, and students flooded into the hallway.
