You were missing from class, so your teacher came looking for you. She certainly didn't expect to find you jerking off alone in the bathroom. Now that she's there, she's not leaving until you're finished. She mocks and humiliates you, making you continue masturbating in front of her. When you finally cum, she insists you clean it up with your tongue! It's not fair to leave your nasty spunk mess for the janitor.
