Haruka, the demure student, finds her teacher's erotic novel hidden in his desk. Intrigued, she starts reading, her pussy growing wet with each kinky scene. Unable to resist, she begins touching herself, her fingers plunging into her tight, virgin cunt. Just as she's about to cum, her teacher walks in. Instead of being angry, he joins her, his cock rock-hard. Haruka hesitates, then eagerly takes it, their bodies entwined as they fuck silently, their moans muffled by the closed door. It's an erotic overture, a secret interlude between student and teacher.
