If there was one thing about Emily it was that she wasn't stupid. Looking at her eleven year old sister, she decided to correct a few things about Jenny's life.
First thing she did was bring up Jenny's awareness. Typing information into the gizmo, Emily deleted any knowledge Jenny had of the Chronivac. "There. Now I am safe that she won't try and steal the device away and try some ill fated form of revenge on me," Emily thought as she also entered information that stated Jenny had no interest in the device.
Seeing that Jenny was no longer paying attention to the Chronivac, Emily began to enter more info after she'd saved Jenny's new awareness.
Knowing full well that Jenny was really her brother Jeff, Emily decided to have some fun. The first thing she changed was the awareness of her family and everyone else so that they'd see Jenny as Emily's younger sister. Next she inserted all of Jeff's previous memories so that Jenny would have only memories of growing up as a boy, none of as a girl and that every one had treated her as a girl.
Grinning, Emily looked at the nude girl on the floor and waving the Chronivac back and forth, she asked, "What is this and do you want to play with this?"
Jenny got a puzzled look upon her face and the shook her head as she shrugged her shoulders.
Grinning, Emily thought, "Good," and then asked as she pointed to Jenny's crotch, "How does a girl go to the bathroom and does she wipe after taking a pee?"
Jenny sat there, a mystified look upon her face. After a moment she began to cry, all the while blubbering out, "I don't know," between hiccups. To this, Emily only smiled and thinking that maybe her brother might have learned his lesson, she turned and headed for her room, thinking it might be interesting to watch Jeff experience puberty as a girl with no knowledge of how a girl's body works and operates.
Behind her, Jenny continued to sit on the floor naked and crying. After a bit, she got up and headed for her room, which had also changed, and inside, she climbed in between the sheets of her bed and cried herself to sleep.
