A timid teen girl, untouched and pure, finds herself in the private study of her stern teacher. He, a man of experience and desire, sees her innocence as a challenge. He begins with gentle caresses, exploring her body, making her feel sensations she's never known. He then guides her hand to his bulging crotch, teaching her the art of pleasure. She tentatively touches, then strokes, growing bolder as his groans encourage her. He rewards her with a deep, passionate kiss, his tongue exploring her mouth. She gasps as his hand slips between her legs, finding her wet, untouched pussy. He fingers her, preparing her for what's to come. Then, with a primal growl, he lifts her onto his desk, pushes her legs apart, and enters her, claiming her virginity in a hard, deep thrust.
