Severe schoolmistress takes advantage of her professor, first by taunting him with his weakness – her colossal derriere. She spreads her cheeks towards him, allowing him to inhale her anal cavity as she passes gas on his face, and he consumes it. She then squats on a classroom chair and urinates directly into his mouth. Finally, she turns around and defecates straight into his mouth. An awe-inspiring episode.
