You find out that you have the same power, time for revenge, you walk into the lunch room and walk up to the girls.
“hay, want to go shopping after school” one said.
“or we could watch a movie at my place” said the other.
“What do you want to do” said the third.
You smirk “you are going to become a boy” you point to one.
You watch as the one you pointed to grew some, hair became brown and clean shaved, the skirt was replaced with pants, and her chest became flat, in a few min later a teen boy was sitting there.
“What did you do, how” said the boy.
“Same as you did, now you are going to become a 5 year old boy” you point to the other.
As the other girl she shrank down, her hair became pig tails, her skirt was replaced with pants with small suspenders, her chest became flat, she started to suck on her thumb.
The last girl stand, “fine I will change you back to a boy” she said.
But nothing happened, looking down she found she was not a girl no more, she was a teen boy.
“Change us back” they plead.
“no, you are better this way and I made it so no one can change you back” you say and your body becomes a teen boy once again as the girl who changed you lost her power.
“How come you changed and we have not” the 4 year old asked.
“Because, I found a way to save your transformations, enjoy your new life” you say as you walk away.
*note that the girls cant change back or get the power agan**
