As Jon stood there, he watched as Wendy's body became tanned, curvaceous, and just totally hot. Her freckles disappeared and her red hair turned blond and fell free from her pigtails. Her clothes changed as well, becoming a tight pink baby-T, a white pleated miniskirt, and pink 4-inch heels. And her glasses and braces disappeared.
She looked down at herself in shock, then asked "What ... what happened to me?"
Biff's eyes lit up. Wendy was exactly the type of girlfriend he always wanted. Sure, she didn't have Sarah's huge rack, but overall, Wendy was definitely hotter. He walked over to her and embraced her. "Hey, babe."
Seeing his opportunity, Jon made a run for it.
