Hermione's spellbook lies open, revealing risqué charms. Her professor, lustful and intrigued, guides her wand, teaching her to cast a 'Lubricus' spell, making her fingers glisten. She tentatively touches her clit, gasping at the sensation. He watches, entranced, as she explores her body, her moans echoing in the empty classroom. He can't resist, moving closer, his hand replacing hers, his fingers sliding into her wet heat, making her writhe and whisper incantations of pleasure.
