Roxie looked on confused but amazed as she saw Amanda's body get thicker with muscle. Amanda was petite but her height started to grow which caused her muscles to tone up. Her shoulders got broader and rounder while her sleeves tightened on her arms. Her arms bulged bigger and bigger until they were a firm 14'' with a few veins showing here and there. Her triceps looking quite beefy to support such tone. Her forearms wiggled as muscle began to fill them as well. They got thicker than a baseball bat and made Amanda looked like she hit weights often as veins sprouted and sinew thickened there. But that was not all, as Amanda;s upper body continued to expand. Her back flared outward, starting to conflict with her shirt which looked real snug on her. Especially in the front as her pecs really defined and lifted her B cups which ballooned some and got bigger until they were ample, sexy C cups. Her shirt lifted some and revealed a very firm, toned 4 pack with ripped obliques on the side.

Amanda curves showed more down her hips as they thickened from her big thigh muscles. Her legs grew thicker and thicker which made her look like she run Track. Her flat butt started filling out to and added muscle to it to lift it up and bulge it out. Her jeans really looking tight but good on her. real good. Since it was only a short, sudden burst the energy soon faded but the results were something to behold.

Amanda was 5'4'' 120 lbs before but now she was 5'7'' and 150 lbs of thick, fitness muscle. Amanda looked really happy as she hugged her new body and even did a few poses. Flexing her arms which stretched her sleeves more as her arms bulged. Amanda looked like she could be on the cover of a fitness magazine as she even had a tan with her firm sexy muscles.

"Wow, girl!! You look like a muscle babe!!" Roxie exclaimed. She had to admit Amanda looked good now. She looked so good that she almost started to rival her but Roxie still had an edge over her.

Roxie strolled over to her friend and began to feel her muscles. They weren't huge but were definitely firm and hard. Roxie then smacked her ass and a loud smack was heard throughout the halls.

"OUCH!! That hurt my hand a little!!"

"What can I say?! I got buns of steel!!" Amanda said. She then jiggled her ass and Roxie stared at the sexy motion as her friend's firm ass looked like it was shaking on her own.

"You look good, but how did this happen?"

"This gun."

Amanda then showed Roxie the yellow gun she dropped on the floor. Roxie looked at it and even saw dials on the side.

"This is some Sci-Fi, wicked shit but if it made you look like that then imagine what it can do to me."

"Trust me, I thought about it but we should wait till after the party to experiment with it. I still got to help you set-up. And clean up your accidents"

Both girls then looked at the spilled beer bottle on the floor and laughed in unison.
