"Teacher, want me to drain it for you? In exchange, let me skip today's extra lessons."
In the quiet after-school classroom sits a little devil gal with failing grades but genius-level sexual intuition. Her overdeveloped body, bursting through her uniform, relentlessly tempts her teacher's sanity. She knows exactly how to drive a middle-aged man wild. As professional pride crumbles, a forbidden private lesson begins in the locked classroom—abandoning all rules and ethics to sink into the bottomless lust of a cute, airheaded student.
