"Teacher! Behind you!!" An elderly teacher whose hearing, vision, and reflexes have all declined due to age. He's famous throughout the school for being so oblivious that you can slack off in his class without getting caught. Taking advantage of this, the girls in the class decide to have some fun. They think, "Since he's always facing the blackboard, maybe we can get away with something erotic?" and start a lewd chicken race, pushing the limits right in the middle of class! It starts with light things like panty flashes, showing their breasts, and kissing... but once they realize the teacher doesn't notice a thing, the acts escalate rapidly! Eventually, some girls even go as far as full penetration... The thrill of knowing they'll be in huge trouble (immediate suspension?) if caught sends the girls' excitement to the max! And the boys get dragged into this dangerous game. The old teacher never dreams that sex is happening right behind his back—and during his own class!
