What Jon and Karyn haven't seen is the slight crack in the stone who appeared just after their last wish.
The day go on as usual and Karyn and Jon goes back to Karyn's house to play video games... yeah, because that's what they do usualy... except this time Karyn is a horny bimbo and she slowly lose concentration to look at Jon's pants...
"Mmh... Jon..." she finally says.
"Yeah ?" Answer the boy still too busy playing to notice her hungry look at his pants.
"I think... I... think you should..." she start to say, feeling hot and almost out of control.
