Karyn reached into the hat, and drew out her first slip of paper. It read "body".
"Uh oh", said Karyn. She drew another slip. It read "enlarged"
Suddenly Karyn's clothes started feeling tight. Jon watched in amazement as Karyn started to grow. He saw the outline of Karyn's new nipple-cocks become clearly visible through her shirt.
After a few seconds, Karyn started having trouble breathing as her bra constricted her chest. She quickly pulled off her shirt and took off her bra, covering her breasts as soon as she could. Jon stood in slack-jawed amazement as Karyn continued to grow.
Karyn's pants started to rip at the seams, so she peeled them off with some difficulty. She meant to keep her panties on, to retain some shred of modesty, but they soon snapped and tore and fell off. Karyn stopped growing when she was about double her original size, completely naked, trying (and failing) to cover up her nudity.
"Shit Jon, how am I going to get home? You have to fix this!"
Jon smiled, wanting to make this last a little longer. "Don't I have to draw three slips first?" he asked.
Karyn sighed, and said "Yeah, you better. Then we're done, though, OK? We need to figure out how to get me some clothes or something."
