"Oh crap, it's swim day tomorrow!" said Jon. "We can't go looking like this!"
"Oh right," said Karyn. "We could just skip, couldn't we?"
Jon chewed on his lip in thought. "I don't think so," he said at last. "I'm close to failing gym class as it is, and if I don't pass, I won't graduate. I have to go."
He looked down at his smooth, wet vagina. "I might be able to fake something down there," he mused.
"I can't go swimming without tits," said Karyn. "There's no way I can hide that. I'll have to skip."
"Not necessarily," Jon replied. "You could just say 'uncle', couldn't you?"
Karyn thought for a moment. "I suppose so. And tomorrow would give us some good opportunities to use the curse. Alright, uncle, uncle, I give up!"
Nipples appeared on Karyn's chest almost instantly, and within seconds her breasts swelled back into the oversized orbs she had before the "interesting" curse. She stroked them gently, smiling to herself.
Jon started to feel aroused. He reached down to stroke his restored cock and found... a smooth, moist cunt.
"Hey!" he almost shouted, "Why didn't I change back?"
Jon's computer beeped. He walked over to it, seeing words pop up on the screen.
I didn't say that the winner would change back once someone gave up. said the computer.
"What?!?" exclaimed Jon, "You mean I'm stuck with a pussy?"
Did you think power would come without a cost?
"Shit!" said Jon, "How am I going to hide this?"
Karyn interjected, "You could use the stone, couldn't you?"
I'm afraid that won't work.
"Why not?" Karyn asked.
The curse is a result of a wish. The stone can't reverse it.
"So I'm stuck with a pussy forever?" asked Jon, sadly.
I didn't say that. I'm sure you'll figure something out sooner or later.
Before Karyn went home, Jon and Karyn had managed to rig up a prosthetic penis made out of socks and rubber bands. They tested it in the shower and it seemed to stay in Jon's swim trunks even when it was wet, so Jon just had to figure out how to change without getting caught. Then they started discussing who they were going to curse the next day, and how...
