The young student's eyes widen as her professor unzips his pants, revealing his throbbing, veiny cock. She gapes, "But I'm here for a history lesson!" he chuckles, "And I'm here to teach you, my dear." She tentatively touches it, feeling its heat and weight. He guides her head down, his hand tangling in her hair as she takes him into her mouth, her inexpert sucking making him groan. He thrusts into her throat, making her gag, but she persists, eager to please. He rewards her by bending her over the desk, her tiny ass in the air, and fucking her hard, filling her tight, shaved pussy with his cum, her moans echoing through the empty classroom.
