Jon was convinced that someone would find him out by accidentally hitting where his balls should be and him not showing any pain.
It never happened, of course. And later it would occur to him that it probably would hurt after all; he didn't have the same equipment, but there were certainly nerves in the area.
At any rate, he was discovered in a completely different way. Two other boys, Pete and Joseph, were talking. "Doesn't Jon look strange?" asked Pete.
"Yeah," said Joseph. "I thought it was crossdressing, but I don't know. It looks like it's right for Jon to have worn that stuff. Could he have been telling the truth?"
"About magic?" said Pete. "There isn't any such thing! It must have been some kind of disguise."
"It has to be real. He'd have to really squeeze his balls to look that way. And he's the wrong shape. The only way it could be some kind of body suit would be if it was a magic bodysuit, and then it may as well just be magic magic. Look at Mark, he's like that too. If you put your hand in front of your face so you can't see it's him it looks like a girl with big feet."
"Do you think he's gay?"
"Who, Jon or Mark?"
Pete waited for his chance, walked up to them, and said "All right, you two, are you really girls?"
"It depends on your definition."
"Do you like guys?"
"A little bit," said Jon. Jon didn't seem to be worried about that; of course they didn't know that if it got him into trouble he could wish away the memories later. "Look, if you're really curious, you can wait until we're done and try some of the magic clothes too."
"You talk about that like it's real," said Pete.
"It is!"
"Well...."
