Amanda sat up on the floor, stunned at the speed and strength that Robert now possessed. Her chest hurt from where Robert pushed her away and she could see the red mark on her chest where Robert's hand had impacted her.

"So," Robert began, staring down at her. "This gun makes a person grow bigger and stronger, I presume?" He laughs a little from his good fortune. "And you were going to, what, exactly? Take all my muscle away to teach me a lesson?" He scoffed.

He turned the gun around. "Oh, it also makes a person taller, too. Oh, this is too good to be true." After a moment of studying the new, strange device, he adjusted the controls on both sides a little. "Let's see what happens when I do...THIS!"

Robert fired at himself, directly in the chest, just as he had seen his sister do to him moments earlier. "Oh, yeah," Robert said, as he felt his body growing again.

He looked down at himself with admiration, as the body he had always wanted, but was unable to get, because of his notorious lack of discipline, was finally taking shape. His already 21-inch arms ballooned out, infusing his limbs with even more power. His chest increased in mass, going from 55 inches previously, to more than 80. His abdominals hardened further, becoming practically impenetrable, as his legs and back increased in size, as well.

His original height of 5'9" was long gone, as he now approached six-and-a-half feet, and showed no signs of slowing down. His legs coninued to lengthen, while more and more muscle was being added to them. Jess looked up at him with lust, barely able to control herself as Robert's body continued upward.

About a minute later, the process was over. He stood nearly 8 feet tall now, close to 400 pounds, with muscles that looked like they could dwarf even The Incredible Hulk's. He felt like a god; his entire body was brimming with power.

Robert looked down at Jess. She barely reached the middle of his abdomen by now. She looked so small standing next to him. He picked her up easily and sat her in the crook of his arm, and she immediately began kissing his face.

He glanced over at his sister, still on the ground. Amanda looked up at Robert in total fear, not nowing what he was going to do next. And she knew that whatever he did, she would be powerless to stop him.

He took one giant step towards her, grabbed her by both wrists and easily hoisted her up in the air, so they could be face-to-face.

"Ooh," Jess cooed. "You're SO strong now." She snuggled up against the arm holding her, and put her head down on his enormous shoulder.

Robert glared at Amanda, the smaller girl still afraid of the monster he had become.

Finally, he spoke. "Relax, I'm not going to hurt you. I will be taking this gun, though. I trust this won't be a problem?" She shook her head no, holding back tears.

"Good," Robert replied. He set Amanda down on the floor and she crawled a few feet away from him.

He turned to Jess. "What do you want to do now?"
