If there was anyone that immediately came to mind when Wyatt thought about this locket, it was the nextdoor neighbor, Mr. Ryan. Terry Ryan was a presence throughout Wyatt's life, and he distinctly remembered being babysat by the older man more than a few times. Terry was a tall, strong and muscular man, and Wyatt distinctly remembered wishing he could grow up to be like Terry. At about 40 years old, Terry was still clinging to his youthful looks even as wrinkles started coming in, his body even in the conservative clothes he liked to wear visibly astonishing. Wyatt could even to this day kind of see the outline of strong, tough abs through Mr. Ryan's shirt.
Mr. Ryan's cyan colored hair and slate gray eyes let him further cut a distinctive profile whenever he was around, and Wyatt remembered hearing Mr. Ryan talk a few times about his life. Apparently he had a pretty high end job, but even still liked doing things like this just to help out.
He remembered about two weeks ago asking to take a picture, which the older man accepted. Looking at the picture and contemplating what he was going to do, Wyatt wondered if it'd be wise to turn himself into a guy that old. The age didn't really show all that much on Mr. Ryan, but Wyatt had no idea what to expect. However a thought about his own current lack of prospects at school made him decide he had to at least try and live a little bit.
Slipping the picture into the locket and closing it up, Wyatt near on immediately felt a hot sensation pass over him, from head to toe. Gasping, the teenager wiped his forehead, feeling it suddenly growing slick with sweat...and then his clothes started to feel tight. His body was all at once starting to grow. He moaned as he felt pecs, actual, strong, huge pecs, pushing out more and more against his shirt. His nipples turning small but somehow sensitive, making him thrash as he fell backward on to the couch.
Wyatt grunted and grit his teeth tight as he felt six tight, brick like abdominals forcing their way into being as his body thickened and grew larger, stronger...and taller. Wyatt was distinctly aware of his pubescent body stretching and pulling, realizing that was probably what brought on the initial hot flash. He felt his shoulders getting so incredibly tight in his shirt as it started to become more and more of a poor fit on him.
Almost screaming, Wyatt tore off the shirt one piece at a time, his shoulders broadening and pushing out - every single side to the shoulders muscling up, developing a contour more like a boulder at least to his eyes. His biceps and triceps responded to this growth by surging and growing, inflating before his very eyes, even his forearms likewise pumping up with size. He had to have verging on 20 inch arms. Even Alex, his little brother, was tiny compared to this.
"Ohh yes..." He moaned and then realized his voice was starting to sound odd, even as his glutes pressed outward and destroyed the seat of his pants, only a few scraps of clothes covering his modesty. Wyatt kicked his legs as he felt them now growing, quads and thighs growing so tight and toned, so large that he guessed from now on he'd be restricted to specially tailored pants or shorts. How in the world did Mr. Ryan dress conservatively with a body like this!?
Wyatt even watched his feet grow larger and somewhat more impressive, and his mind drifted to thinking about if that saying about large feet was true...
Wyatt felt his Adam's Apple grow even as his neck thickened and surged with size, getting something of a "bull neck" to compliment growing trapezius muscles and a widening back. Lats peeking out from behind him at all points. Wyatt's very face started tingling, and he groaned, "Ohh yeah, time for that..." His face broadened and not only became stronger in features, but also started to develop the more weathered looks of Mr. Ryan.
Light wrinkles set in, his hairline very slightly declined, and his hair styled itself into a crew cut right then and there. Even as this happened, Wyatt felt other things going on. His body was feeling oddly tougher than usual in some way. Like his skin was becoming more rough to the touch, less supple. Some very light body hair started to grow in as well, but not very much, considering how much emphasis Mr. Ryan put on his physique. It was pretty obvious he was something of a manscaper.
Wyatt thought he was just about done when he felt a surge of pleasure from his groin.
The grown man gulped and groped at his manhood, feeling his groin getting tighter and his endowment growing larger and thicker. Bigger and bigger it swelled, and even though Wyatt could tell he lost some sensitivity, he could feel his grown balls dangling a bit, and his ten inch manhood peeked out from the ruined remains of his pants. He breathed and tried to get himself up, but he was just feeling out of breath from the exertion of the change.
"Ohh man, that was something else." Wyatt said, and realized he was talking in Mr. Ryan's voice, "Holy shit, it really worked down to the slightest detail!"
After a moment, Wyatt got back up and immediately headed into the bathroom, shrugging off the remains of his clothes and looking in the mirror. His body was magnificently built, everything exactly as he thought it would be looking at the incredibly muscular Mr. Ryan. He felt his body with eager hands, and noted his still rather erect manhood. "Heh, maybe I should take care of you first and foremost. After all, I'll be alone for the weekend."
