Old teacher getting pounded raw in ass by student

My history professor and I fuck after classes in the college whenever we can as we find no one around during lunch and we sneak off to a secret broom and fuck inside there.
My teacher, to my surprise, is avery slutty bottom and every time we do it, he bends over for me and let’s me bang him raw and as hard as possible as he lies down and keeps moaning while getting his ass fucked for hours.
