A light bulb then went off in Adam's head.
If the powder was absorbed into the bloodstream by sinking in to the skin, then surely Marco's bodily fluids would be rich with the powder's magical properties.
There was only one way to find out anyway...
As Marco released another huge gush of cum over the room, Adam quickly grabbed a nearby bucket and caught a hot load of it.
The bucket of cum was like a glass of water to Adam at his now huge size, and he threw it down his throat in one fast,strong movement.
Again he crouched down to the floor and scooped the thick, sticky goop into the bucket, and swallowed the contents. Then again, and again... until his inflated, rippled stomach could take no more of the ultra-masculine cum juice.
"Oooooh god" he began to moan, as his body began to take in the cum's effect. "Watch out Mario here I come!" he thought to himself as he smiled for a moment.
Adam looked down at his body to see it growing at an extremely fast rate. Within seconds he could barely make himself stand, his tree-trunk legs had grown so thick. There was now barely enough room for them to have any range of motion at all.
Soon Adam had risen in height and mass and his eyes met Mario's ballooning pecs and potruding nipples.
His dick and balls were both growing to a size that almost matched Mario's gigantic equipment, and his 50" dick began spraying streams of cum across the room in reaction to the growth.
"No! No!", Mario cried as he looked down upon Mario's rapidly growing muscles.
"I am the most powerful man!! ME!!" he roared in a threatened tone.
In an urgent attempt to maintain his status as biggest man on campus, the huge muscle-goliath wrapped his lips around his swollen bright pink mushroom head cock, and then he let it rip.
Mario took in all the powerful sensations of this act of auto-fellatio, as he had always dreamed of sucking himself off but at an average 6" had only dreamed of this fantasy.
"ARRRRRGGGH!" he cried as his huge dinosaur dick jolted with power and sprayed gallons upon gallons of his own cum down his throat.
His face turned red with effort and anger. Cum sprayed and leaked from the outside of his mouth and even sprayed out his nostrils, but he refused to release the girp of his mouth and continued to swallow rapidly.
But he was too late, within the time it had taken for Mario to suck his own cock head, Adam had reached his size and muscle mass and now stared at him directly in the eyes. Adam's red face became even more red and infuriated at this as his face screwed up at the thought of losing this battle of masculinity.
Adam still continued to swell, beyond Mario's previous mind-boggling record...
Mario's body began to bulge and grow, trailing behind Adam's unstoppable growth spurt.
As Adam reached 40"(over half the size of Mario again), he grabbed Mario's dick with his incredibly beefy, pumped forearm.
Mario, undeterred, continued to gulp his jizz in desperation.
Adam forced Mario's giant dick out of his mouth to Mario's frustration and while it was still cumming all over the place like a fire hose with no pressure-release valve, he jammed it into his own gaping mouth hole.
He eagerly began swallowing the magical cum juice, on too much of a sexual peak to realise he was drinking far, far larger amounts of cum than he had drank earlier to bring him above Mario's size.
With the combined effects of both lots of semen now set in motion, what happened next was absolutely unbelievable...
