Suddenly, Adam started. Someone was turning the doorknob.
Startled, Adam looked round for his discarded clothes. Before he could put them on, however, Mario entered.
"Hey, Adam," said Mario, closing the door behind him.
"Er... hey Mario," Adam answered, slightly embarrassed at being discovered posing in front of the mirror, "I was just... er... working out."
"Oh yeah?" Mario asked, smiling strangely, "You definitely seemed to have got some results."
"Er... I guess so."
"Really, though," Mario said, looking Adam up and down, "You look amazing."
"Um... thanks," said Adam, beginning to notice something odd about Mario's tone.
"That is - more amazing than usual. In fact," said Mario, "I'm guessing you found my little present."
"You mean, you left that box there on purpose?" Adam realised.
"Oh yes," said Mario, "What's the point of having a pretty hunk for a room mate when you can make him even prettier?"
"Is it... safe?" Adam asked, getting a little freaked out.
"Oh yes," Mario said again, "It meets my requirements. Although, I guess there are a few side effects."
"Side effects? What sort of side effects?"
Was it him, Adam thought, or did Mario look taller than usual?
"Well, that depends on your point of view..." Mario began, "In some ways, it's quite a big thing..."
Yup, definitely taller. What had he been doing to himself?
"And in other ways," Mario continued, walking towards Adam, "It's a very small matter indeed..."
He couldn't be that tall, could he? Adam wondered. Then it hit him...
"I'm not shrinking?" Adam said with growing panic, "I'm not..."
His pants fell to his knees...
"You bastard! You knew this would happen!" Adam yelled. He was about level with Mario now - that would mean he'd lost about six inches in height. Half a foot in ten seconds.
"I did indeed," Mario answered.
Adam was delirious. As he got smaller, the process accelerated. He held his boxers to stop them falling down, as he dwindled further. Five foot... four foot... three and half...
"How... how small will I get?"
"You'll be about as small as your average action figure."
"No!"
"I wouldn't worry - you've got the pgysique for it!"
"Noooooo!"
Adam couldn't believe what was happening - his head was level with his desk, but within a couple of seconds he could barely reach the top draw with his hand. Despite his best efforts, he had to relinquish his hold on his boxer briefs. Partly because he had to use both hands to remove his t-shirt lest his midgit sized form should get tangled in it, but mainly because it was far too heavy for his tiny hands to hold - despite his recent muscle growth...
Preoccupied with his transformation, Adam hadn't noticed that Mario was advancing towards his. When he saw the gigantic form of his room mate approaching, Adam backed away. Previously, Mario's form, though attractive, was hardly a match for him - but now, Adam bearly reached as high as Mario's ankle. He had stopped shrinking, it seemed - but now he had a giant room mate to contend with.
"Keep away!" Adam yelled, but all that came out was an ineffectual squeak. Adam tried to back away, but tripped up, toppling backwards into the crotch of his discarded trunks. Before he could free himself, his boxers, with him inside, were lifted in the air...
