Five AV actresses have a serious quiz battle! If they jump into the true or false panel and get the right answer, they'll win 100,000 yen! If they get the answer wrong, they'll be splashed into a wet and messy pool full of colored paint, India ink, flour, and mud! Their faces and pussies will be covered in mud and they'll be in agony! The punishment is WAMSEX while immersed in muddy water. It's like a bronze statue is giving a blowjob? You've never seen such a dirty sight!
