Ty cracked his knuckles has he slowly walked up to Dustin.
"Don't worry, Dustin... You're gonna looooooove this..."
"D-d-don't hurt me.... Please..." Dustin stuttered, as he began to
tremble with fear.
"I'm not gonna hurt you... You're my little brother... Well, you're my
older brother... You need to protect ME... So..." Ty pondered. "How
about some... muscle?"
"M-m-muscle?"
"Yeah... LOTS of muscle... Like the HULK..." Ty grinned, while rubbing
his hands together. Dustin could tell that Ty was just itching to
change him, using his powers.
Then it happened!
Dustin's arms suddenly inflated with outrageous, mind-blowing muscle,
to the point where they were three times as thick as before, and fully
covered with veins as thick as ropes!
"WHOAA!!" Dustin shouted.
Dustin's torso widened by a foot as his shoulders doubled in width,
large mounds of muscle formed all over as his pectorals ballooned out
like beach balls. Mighty ridges of powerful abdominals formed all over
his flat stomach, and Dustin's neck was as thick and as wide as a
bull!
"Uuuhhhhh!!!" he groaned, as Ty looked on.
Dustin's biceps and his calves grew as big as NFL footballs, inflating
to the point where they were as hard as concrete. Lastly, his quads
grew to the size of pillars or oak trees, with thick layers of muscle
forming on all sides, and veins covering every muscle on his body!
"Ooohh MAN!" Dustin groaned, when the growth stopped.
"There... Happy now?" Ty grinned.
Dustin ran his hands over his pecs and his abs before flexing and
feeling his enormous bowling-ball-size biceps. He had gained over 400
pounds of muscle in 30 seconds.
"Amazing...."
"Want some more?" Ty asked him...
