Naive innocent meets her elder lecturer in his dimly lit office, unaware of the lesson he plans to teach. With a coy smile, she listens as he begins, but his words soon turn sultry, his eyes hungry. He leans in, capturing her lips, his hand sliding up her thigh. She gasps, but he hushes her, easing her back on the desk. His fingers find her smooth twat, already damp with desire. She squirms, then moans, opening her legs wider. He unzips, revealing his throbbing cock. She tentatively takes it in her hand, then her mouth, gagging slightly as he thrusts. He pulls her up, bending her over the desk, and plunges into her from behind, her cries of pleasure echoing through the empty classroom.
