"Wait!" yelled Sam.
"Oh, what is it now?" replied Sarah. "I don't have time for this, you'd better go and bring Melissa back."
"But I'm not really a guy... I'm not used to being turned on by girls. Isn't it a bit extreme to kill my boyfriend for this?"
"He's Melissa now," said Sarah. "And she's not your boyfriend. In fact, you shouldn't have a boyfriend now. Tell you what, I wish that you have a girlfriend instead and you will make your girlfriend pregnant with the sperm that is Melissa. Oh, and the girlfriend isn't me, I'm not that stupid."
"But being pregnant in high school...."
"Also, identical twins happen when the fertilized egg splits up, so I wish that after making your girlfriend pregnant, Melissa will be born as twins. Now, go."
"I don't..."
"Stop complaining and go away! I wish you're having sex with your girlfriend now...."
Suddenly Sarah was naked on a bed, with her ex-boyfriend's former girlfriend, now Sam instead of Samantha, erect and getting ready to penetrate her... "What? That wish didn't count? That... ooooooh." She couldn't help but orgaasm as Sam thrust into her and his ejaculation sent Melissa to Sarah's womb to be reborn, now part Sarah. Could it be that the wishes had to be said all in one sentence without taking a breath?
"I... I don't understand," mumbled Sam. "You made me turned on by girls and I just knew that I would cum at the slightest stimulation. But it sounds like you didn't mean for the girl to be you. Well, thanks, Sarah, for being Malcolm's mother. Melissa, as you say. Melissas, even. I guess if I'm your boyfriend we can break up, but you'll still be pregnant. The next nine months will be fun."
"We'll see about that. Because I can...."
