My Student

I got a student that has to be in my office twice a day because he doesn't get on with a teacher,he's always been polite towards me as we get on really well. I've heard from girls talking that he has a big dick they gave him blowjobs, he's cheeky which i let him get away with and lately ive started wearing stockings to get his attention. I know it's wrong with him being my student but i enjoy it. i let him start getting sexual him saying he would fuck me on my desk and i crossed the line by asking him to show his dick. I only wanted to see if it was all true but when he showed me i ended up taking him to the back of my throat. he was leaning back as i was sat in my chair pleasuring my student. it was true he was big i gagged and choked on it when he started fucking my throat my makeup running down my face and then it happened filling my mouth with his thick spunk. I still had his dick in my mouth and he was still cumming when i coughed forcing his cum out. I couldn't swallow it ive never known anyone to ejaculate that much.
