Petite beauty "Ruka," standing 147cm tall, is a diligent honor student devoted to her daily horn practice as a member of the school's wind ensemble. Her pure and earnest nature is captivating. One day, she is suddenly lured away and dragged to an unfamiliar place. There, her lips are forcibly taken, and her expression—blending fear and humiliation—only heightens her allure. A man's hot cock invades her small body, penetrating her virgin flesh. The intense scene of her being taught pleasure for the first time strikes deep into the heart.
