Both girls looked at the rock in Jon's hand. Finally, Athena looked up, confused. "What, you're gonna throw that at us?"
Jon chortled a bit at that. "No. You mean I haven't told you about this rock?"
"Uh, no," said Karyn. "I think I'd remember if you told me about a rock."
Jon explained simply, "It belonged to my grandfather. It grants wishes."
Athena asked, "What are you talking about?" Karyn just laughed.
"I'm serious," said Jon. "It's a rock with magic powers. You touch it, wish, and bang, it happens. So...what do I have to wish to get you two to stop fighting over me?"
Athena moved closer to Jon and put her arm around him, pressing her chest against his side in the process. "Aw, we're not really fighting over you. I just sometimes want you all to myself."
Karyn took advantage of Jon's sudden interest in Athena to take the rock from his hand.
"No, wait --" said Jon, but too late; Karyn was already blurting something out: "If this is a real thing, then I wish for tits that'll really attract Jon's attention."
When the rock suddenly flashed in her hand, she was shocked enough to drop it as she felt herself being forced to look away. And she was shocked again once she could look down at her own body.
