Brad picked one out. "Okay, let's try this one first." He cleared his throat.
"If a spell has done the trick,
and gave a friend a monstrous dick.
This chant will fix it all,
by making his cock extremely small."
Marco felt the tingle again, his big dick seemed to deflate and reel into his body. Inches melted away as it dwindled further and further back. Soon, he had a 1 inch dick again, though at his 6 inch tall size, it seemed to be a foot long. It was a start. "Okay Brad, find another one." Brad nodded and skimmed through the book, looking for a good one.
"Here we go." He said, and he began the chance.
"If muscle binding has become intense,
because you are now far too immense,
Chant this chant and chant it formal,
Your muscles shall shrink to three times their normal."
The action figure sized marco felt his whole body twitch. His ropey muscles began to shrink a little, deflating as the thick muscles returned to normal. Slowly his mobility returned bit by bit. His gargantuan frame dwindled until he was simply huge. He was still way bigger than any professional bodybuilder... but he could move, even though the spell had stopped. Brad noted that it was time to return Marco to his old height.
"If at first you did not think,
and caused another to quickly shrink.
this spell will bring them from their stature small
in proportion they grow until freakishly tall."
Marco slapped his forehead at what Brad just chanted. This guy did have slight french accent... maybe his english wasn't as good as Marco thought. Marco began to grow taller, in proportion again. 7 inches, 8 inches, 9 inches, 10 inches, 11. At a foot tall, he jumped off of the coffee table and onto the carpet, cause he knew he was going to get a LOT bigger. Soon, he was back to face with Brads package, and then his naval, then nipple,soon he was looking down at the young man.
Marco's broad back was now touching the ceiling. He found himself hunching, lower and lower, and lower until he simply needed to sit down. Marco was massive, he was a giant in fact. His body was taking up most of the living room, one of his legs was poking out the door. He had to lay down now. His huge thigh took up the door frame, and his big dick was pressed firmly into the ceiling. Good thing this room was so damn big... he had to be in excess of 20 feet tall.
His pecs were touching the ceiling too, and so was his muscle gut. He looked over at the now tiny looking brad. It seemed he had stopped growing. "Brad, don't try and fix this. I want you to go somewhere for me." Brad nodded again, in awe of Marco. "I want you to go to my boyfriends house, he's upstairs, and he's very fat right now. I want you to give him the book and let him change his body to normal. Bring him back with you and have him fix me, okay?"
"okay Marco, I'll do it." Brad said, writing down the address that Marco gave him. Brad left the gigantic mucleman pinned in the house. He just hoped that he didn't grow any bigger after he left... it'd be hard to explain how his house exploded in a freak giganticising accident.
