A teacher with many problems refuses to come to school due to a monstrous parent... After a three-day teacher's convention, the teacher holds a party to clear his mind and let go of his worries!! The teacher is supposed to talk about his troubles at school, but a male teacher with a different stress gets drunk and plays a prank on a beautiful teacher!! She may look serious, but when she takes off her tight skirt, she is wearing lewd underwear!! In a small hotel room where the female teacher is staying, the men and women pile up tightly, and they move their erotic underwear aside and have a huge orgy!!
