"What a RUSH!" May screamed, her voice sounding louder and even a bit deeper as an apparent result of her growth. She eagerly looked over every inch of her muscular form, rubbing her rock-hard abs through the skin-tight fabric of her shirt while bringing the opposite arm up in a huge bicep flex. "I can't believe this...I never imagined myself with a body like this, and yet now, I can't get enough of it!" The girl laughed heartily while taking a dramatic pose, hands on hips, and flexing her powerful pecs hard enough to tear her shirt completely down the front, giving a perfect view of her ripped abdominals and leaving her inflated breasts only lightly covered by the torn remnants of fabric.
"Can't get enough," she repeated quietly, gazing down at the bag of candies. Without even thinking, she immediately reached in and pulled out a second Rare Candy, shoving it in her mouth and chewing it up with great haste. Within seconds, the tingling feeling returned, now even stronger. "Oh, YEAH~!" May let out an echoing scream of pleasure as she began to grow once more. Her breasts once again went first, expanding out bigger and rounder until they reached an utterly preposterous G-cup, pushing aside the remaining halves of her shirt so that their full glory could be exposed. The already immense pectoral muscles beneath them swelled out even more, till her chest pushed out nearly 2 feet in front of, lifting her massive melons with the greatest of ease and ensuring that they remained perky in spite of their girth. Her abs grew deeper and more cut, eventually developing into an even more powerful eight-pack deep enough to engulf a man's hand.
By this point, she also began to grow in height, quickly shooting up past 6 feet, and then 7, while her back flared out nearly as wide as she was tall. Her arms came next, swelling bigger and bigger around till they were the size of beach balls when fully flexed, their steely surface marked with numerous thick veins. Finally, her lower body began to catch up, with her thighs and calves expanding into treetrunk-sized pillars to support her increased weight, and her ass expanded outward with muscle till it practically annihilated her shorts and panties, leaving her bare from the waist down.
Once the growth spurt was over, she stood 7'5", an enormous paragon of pure muscular power, clothed in nothing but the tattered remnants of her shirt, which clung feebly around her thick shoulders. Overcome with the sensation of growth, she craned her neck skyward and let out a deep, primal roar, most satisfied with what she had become.
