Biff squirmed awake, opened his eyes, but didn't see his girlfriend Sarah still asleep by his side. "Sarah?" he asked, groggily. But then he paused. What was wrong with his voice? He reached up to touch his neck, but ended up grazing one of his nipples. He sat up suddenly, realizing that he shouldn't have been able to get anywhere near his chest, and touching his nipple shouldn't have felt like that. And that's when he looked down and got the shock of his life. He had breasts!
Quickly stumbling out of bed, which wasn't his bed, he found a mirror and stared at himself in it. He was a chick! And not any chick. It was that tomboy Karyn Black, the one that hung around that loser Jon Gibson. Seeing her in just her underwear now, he had to admit that she was pretty hot, but what the hell was he doing in her body?! How was any of this even possible?!
