Transferring to a weak high school boys' basketball team is the strong new recruit Kisaragi Masaru. In reality, she is a girl living as a boy at school. But after an incident exposes her secret, she's forced to pay hush money in the form of her body—coerced by certain students and the coach. The story follows her descent into a sexual world she's never known: aggressive blowjobs, sexually harassing acts by the coach, gangbang 4P sex, and more. As the once-ignorant girl gradually awakens to her femininity, she discovers a new side of herself.
