Another student called Betty (5'8", 135lb, 36DD) who managed to escape the school before was hiding in her basement playing WoW.
The throbbing green unholy energy cracked out through the concrete floor, with Betty thinking that it was a visual effect, there wasn't much resistance as the slime did it's job.
Betty felt a cramping as she clutched her gut. "nnnghhh.... ahhh! What's... HAPPENING to meeee?" she groaned. She fell down on her knees and hands. She felt an intense pressure fill her entire body. She intense pressure kept growing and growing... and so did she! Her arms and legs grow longer and thicker. Her neck grew out inch by inch until her chin reached the computer screen in front of her. Her hands and feet began to expand into monstrous claws, shredding her flawless skin. "Can't.... think..." she said as her thick glasses fell of as her eyes turned a bright, glowing yellow. She grit her teeth together as they grew into large fangs. " Whuh.... HABBENIIIIHHHH...." she roared out. Her skin began to toughen into a rough, dry substance, starting from the tips of her toes and going up to the very tip of her head. Her mouth doubled... then tripled in size. She snarled out loud as drool rained down from her new gaping maw. Betty's thickening body ripped her clothes to bits. Finally, a large, thick waving tail shot out of her tailbone, flailing around as if it had a mind of its own.
