"I think we should. It's nice to help others, right?" Tails nodded in response.

"True, although we're helping her with something... uh... something unnatural." Tails mentally blushed. Helping a girl make her rear end bigger? That's going to raise a boner.

"Well, what are you waiting for, Tails? Help her!"

"Okay, okay, I'm on it!"

Tails was glad he took a lot of time building his ship; one of the features allowed him to used electromagnetic charges to manipulate anyone's body form or function. Don't worry, the charges don't change only what it touches in the body; Tails made sure the waves don't change just the right lung for example, as just touching the body sends the waves' command to the area of interest. This was the perfect time to test it out.

Inputing commands on his controls, the ship whirred, and emanated special waves, hitting the intestinal walls of Amy's butt. The area began to rumble violently; the transformation has begun.

-------------------------


Amy felt something strange in her behind, rubbing her hand on her right cheek covered in underwear. Her hand began feeling a light jiggle, then a mid-ranged rumble. Soon, her entire ass was shanking uncontrollably.

"W-What's happening!" Amy panicked, clenching both her hands on her butt. "Make it stop, please! Suddenly, the rumbling began to slow down, and her hands that held it were beginning to lose their grip, and her underwear was feeling tighter than usual. "Huh? Did it just...?" Turning her head downward, pulling up her skirt to see that her wish had been granted: her butt was now bigger, rounder, sexier. "Oh... my... goodness," she yelled happily. Spinning herself around and rubbing her hand up and down her new form. "Oh ho ho! You'd better be ready, Knuckles," Amy stated, going through her closet for something more... attractive. "Because you're about to meet the new Amy Rose!"

-------------------------


"She sounds pretty happy," Cream said, smiling. Tails nodded in agreement.

"Yeah, she sure does. I'm glad my first test was a success!"

Cream blinked. "Wait, this was your first test?" Tails looked at the rabbit, rubbing a hand on the back of his head sheepishly.

"Uh, yeah. Heh heh... I didn't tell you?" Cream only glared.

"No. What if something went wrong? What if this has gone wrong but we don't know it?"

That made Tails wonder. Were there any side-effects? He hoped not.
