Robert fired the gun at Jess and was successful at hitting her. She moaned as the ray hit her, feeling a pleasure she hadn't felt in a long time. She looked down at herself shortly after to view her growth.

First, she noticed her height, as she shot up a couple of inches almost immediately. Then her muscles began growing. Just a little at first, turning from shapeless flesh to fitness-sized muscle, then more.

The halter-top she was wearing started to rise, her already prodigious breasts growing even more, her pectorals pushing her chest out quite impressively, while the breast flesh itself inflated, too, leaving bigger and bigger mounds of womanly curves in its wake.

Her arms were starting to show tone and definition of growing biceps and triceps, pulsating and pushing their way outwards as they firmed and grew with each moment.

From where she was standing, Jess could feel her shorts shrinking in size, as her legs started to peek through from underneath. Long, powerful-looking cords of quadricep and hamstring muscles poked through the underside of the fabric, as more size flooded her entire body.

After a few minutes, she was nearing 6'3", her body already bigger than any male bodybuilder. Her arms, 22-inches around. "Ooh, don't stop," she said. "This feels SO good." She moaned a little louder, and closed her eyes, imagining herself becoming even bigger.

Suddenly, Jess heard a loud ripping sound, as the halter-top she had on was beginning to tear, due to the increased size of her breasts. They had to be at least EE cups now, and were continuing their journey outwards in all directions.

From behind her, in the floor, Amanda watched, with a mix of horror and jealousy, the growing body of Robert's girlfriend. She watched the larger woman's shirt tear in the back, revealing a Christmas-tree-shaped upper back, wider than anything she had ever seen before. She saw the continually-lengthening legs of Jess, the muscles attached to those legs like tree trunks now, and guessed she had to be near 6 and a half feet tall.

Amanda watched as the hopes and dreams she had for getting some kind of Karmic retribution against her stronger and bigger younger brother vanish, as the hulking body of Jess continued to swell out in all directions.

Finally, the halter Jess was wearing gave way, exposing two very huge, and still growing, breasts for Robert to see. He stared intently, watching the massive orbs extend outward even more, as did the rest of her body. Jess's bra snapped soon after, but as the torn garment hit the floor, her now-exposed breasts didn't sag an inch; they were being supported by the powerful pectoral muscles she now had.

Her already wide shoulders grew more, her round deltoid muscles becoming bowling-ball sized before long, then larger. Her waist tapered into a beautifully compact, yet very-powerful-looking midsection within seconds.

As she neared 7 and a half feet tall, her muscles looking absolutely huge, her body being filled with more and more power with each passing second, Jess could feel her body starting to slow down. She breathed heavily, as the last five minutes were an absolute rush to her, the feeling of being infused with this much strength and size, intoxicating.

She looked at Robert now. She was only a few inches shorter than him, and while his muscles were still bigger than her, she wasn't far behind. If his arms were 45 inches around, hers were no less than 40. His chest loomed at more than 80 inches, but hers was a little more than 70, and with her breast tissue, it seemed to be even bigger than that.

She looked down at her body, marvelling at how big she was now. This was absolutely spectacular. She walked over to Robert and kissed him, hard. He wrapped his thick arms around her, feeling her wide back and huge, but very tight, ass.

Robert massaged her breasts, each one larger than his head, as Jess moaned, and she kissed his neck hard in return. Then, Robert noticed Amanda still sitting on the floor, this time with her knees pulled up to her chest. The pair stopped making out, momentarily.

The smaller girl was absolutely terrified at the two behemoths that stood before her. If she stood up, Amanda would barely come up to her brother's navel. And with Jess, she guessed that her head would come up a few inches shorter than the larger woman's very immense chest.

"So, what do we do with her?" Robert asked.

"Hey, I know," Jess replied. "We can..."
