Well, hello there professor. You left your door unlocked so I let myself into your office. There's something I need to discuss with you. As you already know, I'm not doing so well in your class. Now, I'm not sure if you know this or not, but I'm actually at this university on a track scholarship and if I don't bring up my grade in your class I could lose my scholarship. You don't want that to happen do you? I've seen you looking at me during your lectures and also while I'm walking around campus. It's obvious that you have the hots for me. And you wouldn't want me to leave, now would you? There has to be something I can do for some extra credit. No, not an essay. I'm thinking about something more hands on... or perhaps mouth on. Come here, let me show you just how serious I am about getting a good grade in your class. Your cock is so much bigger than I imagined it would be, professor. This extra credit is so much fun. I'm loving all this mouths on experience I am getting. Mmm, and I can tell you are loving it too. But, I want to do even more. After all, I'm very serious about doing well in your class. So, fuck me. Fuck me right here on your desk. And then, when you're about to cum after I've rode and cum on your cock, I'll take you back into my mouth and swallow your whole load down, so we don't make a mess in your office. I think all that's deserving of an A.
