In school Jo (Left) was the popular girl. Class president, home coming queen, head cheerleader, and all around envy of the school. She was also the attention of every boy, if only because she was a 36D by 9th grade. However Jo was also a terror to every girl who wasn't what she considered "cool" Her favorite target was the "nerd" crowd, and one girl in particular, Kim (Right), she bullied, and harassed all through their freshman and sophomore years. The climax being when Jo and some of her "cool" friends, stripped Kim naked, painted "LOSER" on her body, and tied her to the flag pole.
Kim was considered a late bloomer. By tenth grade she still had only developed to an A cup. She was jealous of the other girls, but mostly hated that Jo would flaunt her much larger boobs to her every chance she got. Accidentally bumping her with her large breasts when they passed in the hall, and laughing at Kim in the locker room when they changed for gym. After the humiliating prank Jo and her friends pulled on Kim, she dropped out and was home schooled for the rest of high school.
Now ten years later all the old class is getting back together. A lot has changed in ten years, but mostly Kim's bust size caught up with her IQ. Now with an impressive 36E's she's looking forward to "bumping" into Jo at the reunion.
The two girls clash quickly. Jo determined to prove she's still the "it" girl, and dish out an even worse humiliation, while Kim is out for revenge after years of living in shame.
