Miki-chan is a cute and cheerful girl who dreams of becoming an idol. She is a bit frivolous and popular in class. But what makes her different from the other girls is that her boobs are growing much faster than everyone else's. Miki-chan's powerfully erotic body has the adults on the street glued to her. Since she has such a sexy body, she attracts the attention of a strange old man. Miki-chan is corrupted by the erotic old man and she grows from a little girl to a slut.
