"Abracabimbo!" Twilight cried, her face blossoming pink as her breasts swelled outwards. "Nngh..." She fell back against the wall, her chest feeling like it was about to burst. It felt like her entire body was being squeezed by some kind of invisible pressure. As she looked down, her body covered in sweat, she noticed that her hips were slowly pushing outward, making her ass grow rounder by the second, pulling her skirt upward little by little. Her thighs grew wider as well, and her legs were now twice as thick. Her skirt began to slip higher up her thighs, causing her to grab it with both hands to pull it down, desperately trying to keep it from sliding up even further and exposing even more of her backside.
"Uggghh... Gah..." Twilight groaned, her pussy throbbing. This was really happening! She had amazing legs and thighs, and a perky bubble butt, and the spell wasn't even done yet! If this kept up much longer, Twilight would be busting out of that skirt!
The spell moved upward, her waist becoming smaller while her hips widened, her stomach becoming flat and toned. All the while, she could feel her nipples harden, rubbing against her top. The spell kept going, her arms becoming toned, her fingers growing long and slender. Her nails lengthened, becoming manicured.
Her chest started to feel bloated, pressing against the fabric of her shirt, and Twilight's heart leapt in her throat. She would get so big... Would she break through her clothes?! But she didn't stop the spell, instead watching in awe as her bust grew, her breasts swelling to nearly double their size, the fabric straining as they stretched. They were even bigger than Rarity's!
"Ah... Ahhh..." Twilight gasped, her voice catching in her throat as her boobs grew even larger, her blouse becoming even tighter. She could hear several buttons creak as they struggled to keep her top closed.
As her chest expanded, so did the rest of her body. Her thighs spread apart, allowing more room between them as her legs got thicker and wider. The skirt slipped even further up her legs, exposing her panties. It was too small to contain her massive hips, and soon the whole thing came loose, falling to the floor with a soft thud.
She could feel her panties stretch as her ass grew, her cheeks spreading outward and making her butt grow bigger. She had such a nice ass now, and it was growing so much bigger!
Her attention was drawn back to her tits as one of her shirt buttons popped off, causing her blouse to open slightly. She could hear it rip as a few more buttons flew away, revealing more cleavage.
"Mnnnggh... Mmmph..." Twilight moaned, her breathing heavy. It felt good to be able to breathe again, after the spell made it so tight around her chest. But the rest of her was feeling so good now too...
She bit her lip, feeling it become more soft and plump. Her lips were getting fuller, giving her a sexy pout. Her eyelashes were long and luxurious, and her eyes were wide and lustful. Her hair had also started growing out, making her look even sexier.
Her heart skipped a beat as she watched her body continue to change, her hips widening, her stomach shrinking, her legs becoming thicker and longer, and yet another button popping off of her blouse. The room seemed to shrink slightly as she gained in height as well, her heels digging into the carpet, her toes curling.
Finally, the last of the spell's energy caused one more surge in Twilight's breasts, finally enough to split her bouse completely open. And with that, the spell was over.
"Ohh..." Twilight breathed, looking down at herself. She was busty and beautiful, her clothing ruined, her legs thick and long, and her ass round and juicy, her breasts plump and perky. She had never imagined she could look so amazing. She had to admit, she loved her new body.
"Wow... I'm so lucky." Twilight moaned, her voice caught by her throat. She reached down and felt her large breasts, her fingers tracing the contours of her voluptuous body. She ran her hands along her sides, feeling the toned muscle beneath her skin. Then, she moved her hands downward, running them over her legs, her firm thighs. She couldn't believe how long her legs were.
"I think it's time to go show my friends how lucky I am..." Twilight said, smiling mischievously, leaving her room to go greet...
