I never knew that the normally neat and tidy and intelligent Ms. Sato was a nipple-tweaking slut... Ms. Sato, who cares about her students, suddenly changes when she sees a younger student who is her favorite... Her dirty talk gives me goosebumps and her nipples get hard, making me a slutty masochist who is turned on by her slutty techniques, and I ended up cheating on my girlfriend and ejaculating multiple times thanks to the teacher's amazing erotic techniques...
