Leave her

"Miss Raymond will spend the rest of the day wearing nothing but my boxers on backwards, and no one will say anything about it. When she gets home, she will realize how she is dressed, and it'll make her so horny, she'll have to fuck both holes with vibrators. She has a large selection of sex toys."

You turn you attention to her directly. With a wink, you say "you just had a student fuck you up the ass. You could get fired for it if I tell anyone."

"Oh my god, you're not going to tell anyone are you, are you, Daddy?"

"You'll be my booty call, so I will not tell anyone. You will also send me a sexy photo of you in only a bra, only panties, or completely nude every morning before you head to work. Do that, and you won't get fired."

"OK, fine. I can do that."

"Oh, and give me a 100% on the test. I'm going to skip class today."

"OK, and you won't tell anyone about it?"

"Not if you follow all of my orders."

"Very well, Daddy. I'll obey."

You leave class, and as you do, you pass a classroom where class is already underway. The door is open, and you peer in.

"Hmmm, couple of cuties in there," you think.
