"I know it's wrong, but my anus is throbbing and I can't stop!" My student Rion and I, her homeroom teacher, are in a secret relationship of S and M. My girlfriend, who is too cute and plays with me like a little devil, hides from the eyes of the other students in the class and we indulge in the pleasure of our "reverse" relationship at a love hotel after school... She uses her slender fingers to stir up my anus in a chaotic way, toying with me and violating me! I'm at the mercy of her little devil temptation, and my student drives me into a corner with her intense strap-on piston, making me cum like a female and turning me into a masochist, and I can't escape from the perverse pleasure! Free trial points available for the first time!
