Mark stared with stunned silence at the weird device in his hand. His silent reverie was broken when he heard the screeching voice of his younger sister, Heidi.
“I guess she found the rubber snake in her underwear drawer,” chuckled Mark.
Heidi and Mark had a long-standing sibling rivalry running between the two. She was only thirteen and was always trying to show-up Mark. For his part, Mark relished playing stupid practical jokes on what he saw as his obnoxiously ambitious kid sister.
“And with this little machine, I can play the best practical jokes ever!” said Mark with a playful smile.
He crept down the hall towards Heidi's room, peeked in the door, aimed the device, and pushed a button.
Suddenly Mark found himself in Heidi's room standing in front of her open underwear drawer and looking at a silly, plastic snake. Mark chuckled at the snake, thinking how ridiculous it was that Heidi was so scared of such things. Yet, Mark was startled by the sound of his own chuckle: it was more of a girlish giggle than a masculine laugh. He next looked down at himself and saw tiny breasts poking out from beneath a pink sweater on his chest. He wore a short, brown skirt and had smooth, shaved legs that were wearing a pair of trendy looking, brown boots. He recognized all of these as his younger sister Heidi's clothing.
"It actually worked," Mark said, still a little surprised to be hearing his sister's voice coming out from his lips. "I've turned into Heidi."
He then pulled the rubber snake out of "his" panties drawer, closed the dresser, and went off to see how his sister was faring in his body. He discovered Heidi (now in his old body) standing out in the hallway, looking a little confused and still holding the technological reality changer remote control.
"Oh, hello there Heidi," said the new Mark. "See anything interesting in your room this morning?"
Mark decided to play it safe and pretend he was really his sister. Because she now honestly believed that she was Mark, he should act the way the real Heidi would have, he figured. He knew, though, that he still had to figure out some way of getting the remote control back from his old body. Heidi didn't seem to be aware of the device she was holding. Hopefully it would be easy to get it back from her.
"Yeah you big jerk," Mark said to his former body. "Thanks for the immature prank. So, what is that funny looking remote control you have there?"
"Oh this?" said Heidi. "I don't know. I just found it. But I know it's none of your business. Why don't you go back to playing with your dolls and leave complex technological things to those of us with brains."
Mark couldn't believe this. Was he really that much of a jerk to his little sister? Worse yet, if Heidi wouldn't give him back the remote, he would be trapped in the life of his thirteen year old sister for the foreseeable future!
