"Teacher! Behind you!!" The old man teacher whose hearing, vision, and reflexes have deteriorated with age. At school, it's said that you can skip this teacher's class without getting caught! There, the girls in the class can also do perverted things when the teacher is facing away during class. Right? Despite being in class, a chicken race of perverted behavior is held at the last minute! It starts with flashings, showing cleavage, kissing... and other light levels. However, when it becomes clear that the teacher doesn't notice at all, the acts escalate more and more! Eventually, some girls even go as far as penetration… If caught, they're out (immediate suspension?) ) The thrill of it has the girls' excitement at max! Meanwhile, the boys get dragged into this dangerous game. The old teacher never dreams that someone is having sex right behind him during class!
