Keyblade Might!

It was a feeling unlike any other; one she struggled to reason. Aqua froze in place, briefly terrified that the Keyblade’s power would overwhelm her, but instead… It seemed the intense energy was now radiating into her body. It felt like a steadily building drumbeat throughout her form, increasing in pace by the second...

She could feel it building up, pushing upward and outward, her body seemingly beginning to stretch or even expand in order to hold in such power

“What’s… What’s happening to me?” she muttered nervously, until she felt a sharp pain hit her body.

Soon she saw how her arms beginning to expand, losing their graceful thin and slender forms, as they began to bulk up with some muscle mass. The rest of her body followed as well. From her chest to her legs, showing several signs of muscle growth.

“Is this the power of the Keyblade?” she questioned as she looked back at it in her changed hand, her nervously expression changing into a small smile.

Aqua’s tone body soon quickly piled up with a lot of muscle mass, as Aqua’s entire frame was pulsing and throbbing madly. Her flat belly became a thick wall of abs in a matter of seconds; causing her shirt to rise up and hug her widen body greatly. The straps got tighter as well around her breasts.

“Such power…!” beamed Aqua in delight, as she found herself throwing her beefier arms around, holding and flinging the Keyblade around like a prized toy effortlessly.

Her upper body thickens up more, as her pecs and back pumped up and down with each breath. Her already powerful looking arms started to gain more ridiculous defined muscles, as her thighs were pushing harder against each other as they thickened considerably with super-strong legs giving her thunderous thighs.

And just like her fingers had changed colour complexion, the rest of her body followed their example. As Aqua’s fair skin gradually became dark and tan-like, her hair becoming paler and her eyes glowing with a sinister gold shine.

“Ooooh…. Yeesss…~!” Aqua mumbled to herself, lifting her powerful arms up towards her face to admire her changes.
