Dr. Sara, who teaches mathematics at a famous secondary school in Tokyo, is a pheromone with a dignified scent that stretches out her legs and keeps the guys watered. One day, when the students were masturbating in the classroom after school when they left school, they happened to be seen by a small dirty janitor who came for cleaning, but they decided to stop using a dirty footjob with beautiful legs. However, the professor eventually found out and was called to the hotel. She receives a neat caress peculiar to middle-aged, on condition that she keeps it secret, and then she is scratched with an adult toy and climaxes her acme repeatedly. And, no matter what, it became a perverted female teacher who loves SEX and actively swings herself, straddling the big teacher's head.
