Sorry teacher, i didn't know anyone was going to be in class at this time. I wanted to speak to you about my grades - I don't understand why I got a C on my last paper, I worked so hard for it. Almost as hard as your dick is getting right now! You thought I didn't notice? I see you looking at me in class, your dick bulging through your pants. It's ok, it's just me and you in here right now, and I won't tell anyone.
