HUNTC-642 "Let's see how far we can go with the dirty stuff during class." A group of super-lewd, mischievous, and sexually insatiable girls decide to do whatever they please during the lesson taught by their laid-back, elderly teacher! Claiming, "We won't get caught no matter what we do," they kick off a risqué game of chicken—with lunch on the line—right in the middle of class!

"Teacher! Look behind you!" The teacher is an elderly man whose hearing, eyesight, and reflexes have all declined with age. He has a reputation around the school for being so oblivious that you can slack off during his class without getting caught. Seizing on this, a group of girls decides to play a daring, super-lewd game of "chicken" right in the middle of class—pushing the limits to see just how far they can go while his back is turned. It starts with mild antics like flashing their panties, showing off their cleavage, or stealing a kiss. But when they realize he truly hasn't noticed a thing, the behavior escalates rapidly! Some girls even go all the way to sexual intercourse... The thrill of knowing they’re finished if caught (immediate suspension, perhaps?) sends their excitement into overdrive! Meanwhile, the boys get dragged into this dangerous game. The elderly teacher hasn't the faintest clue that sex is happening right behind his back—and during class, no less!
