"Welcome, students, to today's lesson in the art of self-pleasure," the professor, Misterdoktor, announces, his eyes locked onto a busty, shaved redhead in the front row. She squirms under his gaze, her pussy already damp with anticipation. He continues, "Today, we'll explore the wet, the wild, and the taboo. Our little slut here will demonstrate the fine art of fingering, for your... edification." The room falls silent as the redhead, her cheeks flushed, slowly spreads her legs, revealing her slick, pink pussy to the class. She begins to stroke herself, her fingers gliding effortlessly over her sensitive flesh, her breath hitching as she loses herself in the moment.
