"It can't hurt, I suppose," said the female Jon. "But it scares me a little since the way the wish works, I'm going to like it."
Jon embraced his girl double... and at that moment Jon's mother opened the door and said "Jon, Jen, wash your hands. It's time for dinner."
"Er, yeah, Mom," replied Jon.
Jon's mother paused. She looked at Jon and "Jen". Jon had Jen in his arms as if they were lovers--which they were going to be in a moment--and her eyes were widening. "Jon... WHAT are you and your twin sister doing?"
Jon, thinking quickly, made some wishes. "First, I wish Mom would leave us alone for the next few minutes."
She suddenly left the room without saying a word.
"Now, I wish Mom forgot that she saw or heard anything strange when she came in here. I think that should do it."
"I'm getting hungry anyway," said Jen. "We can continue later."
"I'm getting hungry too! We can continue later, but I think we're going to need another wish. We can't be brother and sister and have sex."
"Do we really need one?" asked Jen. "The wish only lasts until the condition ends. It doens't matter who we are if we won't stay this way anyway."
Jon shook his head.
Then Jen realized. "Oh no--we didn't give it a condition! But... wait a minute. We can probably wish up a condition."
The two went to wash their hands and then walked towards the dining room. "Remember," whispered Jon, "right now we're twins. We're not identical twins, but we just happen to look alike down to the last freckle and scar by complete coincidence. We have to act like sister and brother when we're not alone."
