PIYO-111 A tomboyish high school girl who, after confiding in a teacher that she was troubled by her masculine traits and wanted to become more feminine, was pushed into premature development and ended up overwhelmed by intense pleasure

A teacher takes advantage of a timid young girl who comes to her for advice, asking, How can I become more feminine like you? The girl says boys make fun of her for not acting feminine enough. In the first half, the teacher uses the pretext of helping her become more feminine to make inappropriate advances. The girl’s immature body reacts on its own to the teacher’s seductive teasing, and even a physical education teacher gets involved. Pressured by both women and men, the girl is led to discover new feelings.

In the second half, the teacher says, You want to become more feminine, right? I’ll help you. The more you follow the teacher’s instructions, the more feminine you’ll become. The girl is then threatened and manipulated by other teachers, and forced into repeated humiliating situations. The teachers tell her, We’ll make you into a real woman. After being pushed to the limit again and again, she is made to experience overwhelming pleasure and is forced to discover a new side of herself.
