"I really should spank you, you know. Put you over my knees and take your pants down. Give you some smacks! Think I should?" She was giggling a little.
Finally, I found some backbone. "This is ridiculous! I am a tenured professor at an acclaimed college! You are just a girl! I demand respect! You will not be treating me in this manner!"

"I am going to be kind to you dear, though you really do deserve to be punished for that outburst. But I am losing patience with you. Now put your thumb in your mouth and listen to what I'm going to say. Don't even think about taking it out until I give you permission. NOW DO IT!"
