That JAV

Rui is a traveling instructor. One day, she went to Satou's house. Satou is a very creepy guy, and Rui, with her wits about her, senses something is wrong. Rui, who has a keen sense of humor, senses what is wrong with Satou and, as usual, she is going to take his expensive lesson fee and say goodbye... But she is manipulated and controlled by a vulgar instructor, and is transformed into a slobbering, but infinitely cumming sex ractor.... They are going through the 60-minute pee-filled course....
