Amanda moved quickly down the hall towards where Kelly’s locker was located. She was used to having to navigate the crowds by weaving in and out of the myriad of students that lined the halls, but now with her tank of a body the crowds parted as she approached. She found her travels were much quicker than usual. She rounded the corner and saw Kelly gathering books from her locker; since hers was on the top row she had to stand on her tip-toes to reach everything. Amanda hung to the opposite wall and did her best to blend in, which was no small feat since she was easily twice the weight of anyone around her.

She pulled her backpack off and unzipped the main compartment where the gun was hidden. She carefully considered the settings she would use on Kelly. Since a setting of 15% had given Amanda an additional 6” in height she thought 35% would be more than enough to make Kelly above average (she briefly thought to herself what a 100% blast would to to a person, perhaps make them at 20’ tall giant). Amanda then turned the muscle growth dial down from 65% to 30%. She wanted to give Kelly a boost, but didn’t want any challengers to her muscle crown. Selfish or not she wanted to be the biggest of them all by a strong margin.

Amanda turned to her side and poked the barrel of the gun out through the opening of her backpack aiming squarely at Kelly’s back. She waited until a sufficient gap appeared in the foot traffic in the middle of the hall so she wouldn’t accidentally shoot a passerby then fired. The blue beam enveloped Kelly’s body and time stopped.

Amanda was unable to move but was aware enough to witness Kelly’s shape-shifting. Within moments Kelly was far from tiny as her head surged upward toward the top her her locker. Amanda noticed that most, if not all, of Kelly’s new height came from her legs which were rapidly lengthening. Kelly’s blue jeans had vanished having been replaced by a pleated skirt (of the “school-girl” variety only shorter) with a black and dark green plaid design on it. Her legs were shooting downward out of the skirt like weeds photographed by a time lapse camera, the distance between her hips and her black, mary-jane style shoes. After half a minute Kelly’s legs rivaled Stacy Keibler’s in length, though Kelly’s height continued to increase until she topped out at a full 6’ 1” (now her spectacular pins had beaten Ms. Keibler’s in length by a good 2 inches).

That was when Kelly’s body began to inflate, packing on muscle at a rate that would have been alarming under any other circumstances. Kelly’s white polo shirt had morphed into a long sleeved blouse of a dark green color that matched the dark green stripes of her skirt. The material of the top seemed alive as her body grew and grew beneath its surface, pulling the fabric taut. Her shoulders were wide and thick while her arms looked ready to pop out of the sleeves. In the instant before the threads of the shirtsleeves began to pull apart from the pressure of her incredible biceps her upper body finished it’s expansion.

Kelly’s lower body, though was still going strong. Her legs had been growing thicker and thicker right along with the rest of her and by this point were well over 20” in girth. As they continued to pack on powerful pounds the valleys and ridges between the various muscle groups became deeper and more cut. By the time the growth subsided her calves were 23” around while her thighs were as big around as Amanda’s arms, 34”.

As one last change Kelly’s hair thickened causing the scrunchie that held it in a pony tail to snap free and vanish in mid-air. Her dark hair cascaded over her mighty shoulders in waves.

Finally the blue light that surrounded her exploded in all directions adjusting the past to Kelly’s new dimensions.

Once Amanda was able to move again the first thing she noticed was a trio of boys close behind Kelly with their eyes as big as dinner plates staring at her amazing legs. It appeared to Amanda that Kelly’s upper body was about the same size as her mother, Stacy’s, while Kelly’s lower body was far more swollen. It was quite obvious what Kelly’s favorite muscle group to exercise was.

Kelly finished with whatever exchanges she was making with her locker and closed it, then turned to head to her first class which was two doors down to her left. Amanda was now finally able to see Kelly’s front and her heart nearly skipped a beat. Kelly’s face, always beautiful, was beyond striking. It was her smile, Amanda decided. Not much had really changed, but she now carried a confident smile that light up the entire building. Atop her enhanced pectorals were a pair of breasts that resembled a pair of cantaloupes. Amanda guessed she would have worn a D-cup bra, where she to wear one at all. The top two buttons of Kelly’s blouse were open revealing cleavage nearly down to her nipples. The boys who had just seconds ago been laughing and grinning were stunned into silence as the super sized Kelly moved past giving a wink. Later the boys would argue over exactly who it was she had been winking at, an argument that would come to blows.

Amanda marveled once more at Kelly’s magnificent legs while she walked, watching as each muscle in her thigh relaxed, bounced, jiggled and flexed with each stride; her quads, hamstrings, and glutes were bursting with untold power. A warm feeling engulfed Amanda as she realized she had created a goddess on earth.

Once Kelly was inside her first period classroom Amanda took off headed towards her own. At the end of the hall she passed Sarah, the head cheerleader, who stood in silent awe of Amanda. The two girls were about equal in height, but Amanda knew that it would take at least three Sarah’s to match her in weight, and far more to equal her strength.

Could this day get any better?
