After school, a man and woman who appear to be teachers have a secret rendezvous in the clubroom when the students are gone. It seems that sexual misconduct on school grounds is a common occurrence for them, and they lock the door with practiced hands and begin to devour each other as if a dam has burst. They are extremely excited by the sense of immorality and thrill that their lives will be over if they are found out, as they squirt and cum in large quantities. Even people who appear serious on the surface are actually hiding some outrageous sexual fetishes.
