I need better grades. so i have only one choice

First you are a little shocked but you think about your future and realise that you need to do this. You begin to stroke his realy big cock inside his pants and you can feel how it grows bigger fast. "Ahh. Yes. I know i can do things like that with you" your teacher moan. You continue with stroking till he aks: "Do you know what bring you more better grades?" You stop stroking him, look at his eyes and don't know what he want but then he whisper in your ear: "I realy want to know how you mouth and tounge feel on my hard cock"
