The cheers grew louder still. "Of course you could use some extra muscle!" Loki said above the din. He waved his arms again for effect.
The male students felt their bodies swell. The noise died down as both the boys and their dates watched the changes in awe. Now the room was filled with the sound of the seams ripping on rented tuxedos. Through the holes, it became easier to see the increases in bulk and definition. Some of the guys went so far as to rip off the remnants of their jackets and shirts, looking down, amazed, at the perfectly formed pecs and abs they now possessed. More seams ripped as other guys flexed their biceps and triceps.
Loki said, "Those muscles don't look good with body hair, so let me get rid of that for you guys, too. Might as well give you permanent bronze tans while I'm at it, except for you Goths, of course."
One of the male Goth students, looking even weirder than usual with his newly enlarged but still pale body, removed his top hat and bowed toward Loki. The other males in the room, save a few non-Caucasians, only watched as their skin darkened a varying number of shades.
The trickster continued, "But don't worry, ladies. I'll make you bigger, too, but only in one area." He pointed to his chest with one finger and drew a circle; with his other hand, he pointed out to the audience.
The sound of the room became an excited murmur as the girls felt their chests inflating, their milk glands enlarging, their breasts swelling to sizes that might be best described in terms of sports equipment.
Loki started, "Now, I've given you more internal musculature, so --"
He was interrupted by a girl's voice. "You've gone too far!"
"Excuse me?" He looked down from the stage.
A redhead, her skin smooth and perfectly tanned, looked up at him with flashing eyes, trying to save her dignity by holding the remnants of the top of her dress over the large spheres that were now attached to her chest. "I said, you've gone too far!" she repeated.
There was near-total science in the room. People stopped looking down at their transformed bodies and looked anxiously at Loki. Finally he grinned. "You think I've gone too far, Colleen?" -- that may not have been her name before, but it was now -- "You think I've gone too far? You haven't seen how far I can go."
