A lovesome girl, eager to please, finds herself in the private office of her older, bald lecturer. He, with a look of cunning, offers her a puff of his pot and a chance to raise her grade. She hesitates, then accepts, feeling a rush as she takes a drag. He moves closer, whispering, 'I have another kind of lesson in mind.' She blushes, but her curiosity piqued, she agrees to his terms. Dropping to her knees, she wraps her lips around his throbbing member, taking him deep into her throat, gagging slightly but eager to please.
