When the class goddess turned evil

Looking up at her, you lamented the days before she gained her powers ...

She had always been excessively pretty and, because of it, successful with everyone who was around her ... every boy wanted to go out with her, and every girl wanted to be her ... yet she never had much of an ego.
Little did anyone know, hiding under that pretty face, was evil incarnate.

It happened only a week prior, as one of the buys was hitting on her, after rejecting him she uttered the words "wish I had the power to rise above all of this ..." under her breath, but not quietly enough for you to hear it.
The next day, another one of her suiters approached her for what had now become a daily ritual, but this time, and quite openly she told him that she wished he was so small she would be unable to see him.
She was clearly growing tired of the daily routing of people confessing to her.

But this time, and before everyone's very eyes, the guy actually shrunk to the point she, and everyone else, was unable to see him.

At the same time, she developed a wide grin on her face, unsure if it was her doing or not ... but, losing no time, and before anyone else could react in time, she looked at the guy next to me, who'd confessed the day prior, and said "I wish you were so small I could step on you".

To everyone's horror, he too began to shrink, and once more, before anyone could react, she turned her gaze towards me, approached quietly, then looked down at her feet, ordered me to get on my knees.

Not wanting to have whatever happened to the other two happen to me, I obeyed her orders, but while doing so, she uttered "still too tall" "wish you were just a little smaller".
With those words being said, I too began to shrink, but only a little as my entire body now only reached her waist.

She smiled with satisfaction as she then ordered me to remove her shoes and socks, then, shocking everyone still in the room, lifted her foot and crushed the student beneath her big toe.

"eww, what a mess he made"
"clean it up, lick my foot clean ... NOW"
