Jake just couldn’t get enough of his second set of biceps, as he stared at his reflection in the clear river water. He had flexed each arm three times already, and he marveled at the two huge baseball-sized biceps, which sat neatly next to each other on his incredibly wide arms. Truly, his arms seemed amazingly wide for a ten year-old!
“Damn, I’m strong…” he murmured to himself, as he continually felt the double dose of power.
But what came next, caught Jake completely by surprise. The strange river water first had caused his cock to grow a duplicate. Then, he grew duplicate biceps on each arm. Now, something else was about to happen.
Suddenly, Jake was overcome by a powerful tingling feeling which spread all over his torso. It began in his shoulders, and it caused two big lumps to sprout on either end of his shoulder. Then, the tingling spread to his abdominals and his chest.
“Hey… What’s happening?” Jake gasped, as he began to feel the changes.
Suddenly, Jake felt his entire upper body widened dramatically as the lumps on either side of his shoulder grew bigger at the same time. He felt his ribcage expand and he felt something like his lungs and heart and stomach create duplicates internally as well! As his torso doubled in width, the lumps on either side of his existing pectorals grew into new pectoral muscles!
“What---?” Jake gasped as he looked down at his body. He suddenly realized he now sported FOUR pectorals, lined up from left to right, just under his shoulders! Then, under his pecs, he had two sets of abdominal muscles! His torso was now nearly four feet wide! Not only that, but his four pecs grew slightly bigger, like four half-sized soccer balls, which were hanging from his upper torso next to each other.
When Jake ran his hand over his pecs, he felt his heartbeat in two different areas!
“Oh no! I’m really turning into a freak now!” Jake wondered. He has two cocks, two biceps, two sets of pecs and two sets of abs and two sets of hearts and lungs! What’s going to happen to him next?
