The new Goth girl Jon watched in dismay, as the boy (who she only vaguely remembered was her own original body) first became female, then acquired DD-cup breasts and long blond hair.
The new preppy Sarah (which didn't look exactly like the old preppy Sarah, because her body was basically just a female version of Jon's body) smiled happily. She hated the cheerleaders and all the other preppy idiots at school. And she figured that the best way she could ruin their lives was by infiltrating them and destroying them from the inside.
She laughed wickedly, as she thought out her vengeful plans.
