A secret act that takes place in the infirmary... A small devil-type slut teacher attacks a masochist man with his propensity fully open! A masochist teacher and a masochist student who come to be bullied because of poor physical condition. A genuine M man who appoints "Natsuki" who works as Miss S. Anal torture that men who want to be blamed by S sluts are crazy about. I'm sure you will be captivated too...
