Mei, the most popular beautiful swimming instructor at the gym, is temporarily in charge of a middle-aged men's class. She gives a half-hearted and careless instruction, and they fabricate a sexual harassment story... The students are furious at Mei's attitude, and they carry out a group rape of her in revenge. "Hey, what are you doing!?" She is half crying as she is surrounded by many penises. They force their penises into her small mouth. She gulps and the deep throating doesn't stop. They make her wear an extreme swimsuit that is more erotic than naked, and destroy the pride and pussy of the arrogant big-boobed woman. They penetrate her one after another and cum inside her in revenge. They pour a lot of thick semen into her. They rape her with all their might to make her understand her position, and in the end she starts shaking her hips of her own accord (lol). It's not good to look down on people, teacher...
