"I know it's wrong, but my anus is throbbing and I can't stop!" My student, Nonoka, and I, her homeroom teacher, are in a secret relationship of S and M. My cute girlfriend plays with me like a little devil, hiding from the eyes of the other students in the class. After school, I was drowning in the pleasure of our "reverse" relationship at a Ke'ai hotel... She uses her slender fingers to stir up my anus in a chaotic way, toying with me and violating me! I can't escape the perverse pleasure of being made to cum like a female by my student's intense strap-on piston, which makes me a masochist, as I am driven to the mercy of her devilish temptation!
