In the quiet of the study room, the aged teacher's voice drops to a low, seductive rumble, guiding the young bookworm's hand to his crotch. She feels his hardness, her eyes widening in realization. He unbuttons her blouse, revealing her small, perky breasts, and she moans, her wetness soaking her panties. He pushes her head down, his cock throbbing as she tentatively takes him into her mouth, her tongue exploring his length. He grunts, fucking her face, his hands tangled in her hair as he teaches her the oldest lesson of all.
