The cabin had been keeping a mental eye on Jack. Young and strong and virile, so much potential...it began to get to work on him.
Jack began to feel achy. It started in his legs, which he attributed to still needing to stretch them out. But soon the feeling spread to his arms and his entire torso, which began to sag. Weakly, he returned to the cabin and fell onto his bed.
"What the heck?" he breathed. But then he realized his voice sounded deeper and huskier. He reached for his throat and felt an enlarged Adam's apple and some stubble, which he followed all over his face. He grew even more confused.
Jack realized his clothes were feeling tight, especially his shirt. Raising his head up off the bed enough to look, his view was blocked by two large mounds. His eyes went wide as he realized those were his pecs!
Jack bolted off the bed. He was much taller now. He looked down at his torso, to which his shirt clung tightly, leaving nothing to the imagination. In addition to his huge chest, he now had a washboard 8-pack of abs that stayed defined even when he relaxed. His biceps now measured like tennis balls, straining the sleeves, while his jeans hugged his pillared legs. He also had quite the bulge!
Jack was ecstatic. He looked like Jeff Said, except himself (Well, at 18). And he was significantly bigger than Will now in every way, more than enough to undermine any authority his brother might have held over him. He could do whatever he wanted!
He started by stripping down to his underwear and posing in the mirror, showing off his defined muscles. His face was model-handsome; maybe he should look into that? If only the girls oglf his class were here to admire and fawn over him; then the image would be complete!
