Teacher Rin falls right into her student's trap, obediently submitting to his every desire. Even before class begins, she satisfies his lust without resistance, willingly taking him deep despite the forcefulness. Any attempt to resist is met with verbal humiliation and increasingly intense teasing.

His depravity knows no bounds, eventually dragging classmates into their lewd games. Constantly under his control and fulfilling his desires, Rin's demeanor carries a melancholy air—yet her strength and unwavering loyalty remain unmistakable.
