That's what happens when you get burned by your math teacher. You must know how to make amends... We're going to start with a nice spanking, and since that's not enough we're going to have to go on with a good blowjob. And obviously since our little bitch still hasn't figured it out, we're gonna eat her pussy before we fuck her on the desk. By the way, we'll even take advantage of it to fuck her so she understands once and for all.
