"Yeah sure, I'll go to Mr. Yuan's and get you that ointment. Buuuuttt first I want to see something -"
"What could be more important than this?!"
"You growing bigger ... much bigger."
"Dude, if you don't do something soon, there's no telling how big I'm gonna get!!" Guy said in panic as his muscles continued to swell.
"I know, but I want to see you become the biggest muscle freak there is. It's kinda been my fantasy for a while now."
"Wha!? Fuck dude, why would you ... ooohhhaaahhhh" Guy cut off as his body suddenly experienced a surge of newfound growth.
The top of Guy's head brushed against the ceiling. He put his hands up in an effort to push himself vainly down, but apart from being unable to bend them to the full degree necessary, the power that exuded from his wrecking ball biceps caused cracks to form in the ceiling. Small pieces of plaster fell down to the floor below, which Ryan dodged as he stared in order at his growing friend.
Still Guy continued to swell. He bent his legs to kneel on the floor in order to accommodate himself, but it was no good as the growth responded by surging his bloated body bigger. His muscles grew in all directions, causing Ryan to step back so that he could gain a better view of the muscle show. His back against the wall, looming over him was a giant swelling musclebound monster that was Guy. The abs that were apparent on his muscle gut continued to grow bigger and larger in proportion to the bloated form. His gigantic pectorals rested on top of them, crowned by two fattening nipples that were as big as Ryan's fist.
"Ahhh .. fuuuuuccckkk Ryan ... why didn't you go to the ... aaahhhhh ... ointment store ...." Guy moaned as his face was overtaken by his swelling pecs and traps. His cannonball delts squeezed at the walls of the confined room, arms packed with so much power that the walls began to creak under the muscle beast's growing body.
Ryan smirked. "I would have, Guy. But watching you get this big is such a turn on that I couldn't resist."
He gingerly clambered up onto Guy's semi-erect penis, which had by this point grown to the size of at least a normal man. His testicles were now the size of beach balls, and showed no signs of slowing down their growth. He pawed his way up the spherical wall that was his friend's muscle gut, carefully placing his fingers in between the deep grooves that were the abdominal muscles. Taking care to pinch each fat nipple as he climbed, he made his way over the monstrous pec shelf in between the chasm where they met.
He had reached the ceiling now, were Guy's head, traps and pecs were pressing against the top of the room. Cracks had begun to appear where the giant bodybuilder's sheer girth had pressed against the walls and ceiling. Guy moaned loudly as his body grew bigger and bigger, struggling to fit into the small room with his muscular frame.
"How are you feeling, big man?"
"UUUGHHHHH FFUUUUUCCCKKKKK ...." Guy moaned.
A loud crashing sound could be heard as Guy's mammoth cock pierced its way through the wall behind Ryan. It had begun to ooze pre cum in response to Guy's arousal over the growth.
"Shit, that's fucking hot man. Your dick is strong enough to pierce through concrete walls."
"You fuckin' think this is funny? Wait till I get control of my muscles. I'll ... UUUUGGGHHHHHH .... flex ya' to death ....."
"Well I wouldn't do that at the moment. After all .. I may be able to do something for you ..." Ryan said as he looked upon his Muscle Giant's steadily growing body.
