Mario stood frozen in a mixed state of fear and lust. Adam now loomed over him. He was a virtual muscle god with a huge cock to match. He was horny, stroking himself and Mario did want to help... but everytime Adam got off he would just get bigger. And the bigger he got the hornier he got. Mario tries to back away but Adam stops him, grabbing him by the sholder with a big strong hand.
"I want you to help me Mario!"
Adam forced Mario against his cock. He couldn't understand why anybody wouldn't want to touch his giant, hard, two foot phalic. It was his god, all he wanted to do was please his cock and his cock wanted to be touched by as many men as possible. Worshipped by as many men as possible. That's why his cock was making him so big and strong; so that he could make as many men touch it as possible.
Adam continued to rub his housemate against his cock, harder and harder. Mario tried to call out, make Adam stop but he couldn't get his attention. "Lick it Mario! You need to lick it! And Kiss it!"
Adam tried to force his cock into Mario's mouth but his cock was too big. Adam couldn't fully understand why his cock was too big for Marioa's mouth, but just the sight of another man's mouth agains his cock made Adam so horny that he blew another load. Not that it was any kind of release for Adam, but Mario was knocked across the room by the force of the jizz.
Once again Adam grew: bigger and more muscled and hornier! His massive weight caused the floor to give out from under him as he continued to grow... not stopping untill he was at least 16 feet tall...
