Good student used hard

I was just about to study for the exam that we will write at the university tomorrow. Then he came to me and said I could take a break. Well, I've been cramming for several hours and a break will definitely do you good. However, I would not have thought that 2 seconds later I already had his cock in my mouth. He pushed his big cock deep into my little fuck mouth and took turns fucking me. Finally he took me hard from behind
