"Okay, I'm the sexiest, prettiest, perkiest cheerleader in school, and you're my quarterback jock boyfriend."
One second, Karyn and Jon stood there, looking as she'd always rememebered them. Then the next, everything changed.
Karyn gasped as she realized that she was now dressed in a cheerleader's outfit, complete with midriff-baring top and short, pleated miniskirt, saddle shoes and the school logo and a stylized KARYN embroidered over her left breast. She also realized that rather than being cute but fairly unremarkble (aside from her well-developed bustline), she was now in perfect physical condition, and probably a knockout to boot.
"Gee, Karyn," said Jon, "That won't work." Jon's changes were as remarkable as her own. He was now a good 3 inches taller than before, with a bulk of muscle he hadn't had before. He looked like a solid wall, but when he moved as he was now moving towards her, he moved with the lithe grace of someone who could sidestep a rushing defensive back. He was now clad in a jersey and a leather jacket with a school letter on it.
"Wh-what do you mean?" Karyn asked nervously. She'd never let herself feel and attraction to Jon, but now the sight of him was making her stomach do flips and her brain feel a little giddy.
"Well, you were supposed to tell a lie, right?" he asked, as he folded a well-muscled arm around her shoulder.
"Uhhh..."
"But see, everyone knows we're together. Always have been, always will be." And with that, he tilted her face up and gave her a kiss.
Oh wow! she thought as he broke off with a smile. Wh-what have I done? I better fix this! But do I - do I really want to?
