The lecturer's gruff voice commands, 'Come here, kitten,' as the young student approaches his desk. He pushes his chair back, revealing his hardened cock straining against his pants. 'You've been a bad girl, haven't you?' he growls, pulling her close. She nods, her eyes wide with a mix of fear and excitement. He unzips his pants, his thick, veined cock springing free. 'Then you know what you deserve,' he says, guiding her head down. She takes him in, her inexperience evident as she struggles to take his length. But she's eager to learn, and he's more than willing to teach.
