A young, innocent student finds herself alone with her older, experienced instructor. He notices her nervousness and takes advantage, guiding her hand to his throbbing bulge. She hesitates, then tentatively strokes his length through his pants. He unzips, revealing his thick, veiny cock, and she tentatively takes it into her mouth, her inexperience clear. He guides her head, fucking her throat gently at first, then harder, making her gag. She looks up at him, tears in her eyes, but he just smiles, enjoying her innocent struggle.
