Hot Instructor Shits On My Face

She was very disappointed with my grades in graduate class and tells me that I deserved a lesson for a job poorly done. She goes down on her knees and opens my pants, the bitch grabbing hold of my stiff pipe. She thrusts me down the floor and takes off her skirt and undies, then she sits on my face, rubbing her asscheeks all over me. I fingered her asshole to stimulate it, then she lets out a stream of watery shart, sticky and foul-smelling shit getting all over my body!
