Amanda fired the gun into her midsection and gasped at the warm sensation she suddenly felt. Slowly, her muscles began responding to the gun's energy.

Her body felt lighter for some reason, as the initial wave of muscle growth flooded into her body. First, her midsection tightened up into a prominent six pack, with her oblique muscles running down either side. Then, her arms began to grow, turning from the shapeless form she had always known, into a pretty healthy-sized bicep in under a few minutes. Amanda experimentally flexed her arm, excited with the change. It looked to be close to 15 inches and showed no signs of slowing down.

Next, Amanda looked down to see her quadriceps starting their transformation. Thick cords of leg muscle began filling out the tan khaki shorts she was wearing, as the four major muscle group in her legs grew immensely. Before long, her leg movements were becoming constricted, as her quadriceps and hamstrings had filled out her shorts to the max.

Amanda was startled as she heard a tear forming along the side of her shorts, followed by a hole ripped into the rear, as her butt firmed and rounded, too. She had to admit, this WAS exciting, but she hoped that no one was watching her...

Amanda ran her hands over her now rigid stomach muscles, amazed at how her body ad been transformed in jut the past couple of minutes.

Her breasts had been growing this entire time and Amanda noticed that they had to be at least a C up by now, and were continuing to expand before her eyes. She felt her pectorals grow as well, adding a shelf of muscle to help support her growing mammaries. It felt like her bra was going to snap in two at any moment. The material was digging painfully into her skin.

Her back flared outward, giving her backside that classic "Christmas Tree" look and giving her bra the excuse it needed as it finally gave up, snapping in two pieces. Amanda sighed in relief, rubbing the sore spot on her chest.

Her shoulders grew broad and massive, swelling outward.

Finally, as the process was winding down, Amanda saw a thin layer of fat cover her muscles, covering up her newly acquired definition, but in so doing, made her body appear even bigger and more powerful.

Amanda rubbed her hands over her huge upper arms, amazed at the overall size now. "Good thing I wore a tank top," she thought to herself.
