Mei, the most popular beautiful swimming instructor at the sports gym, is temporarily in charge of a middle-aged men's class. Her unmotivated and careless teaching leads to a fabricated sexual harassment story... The students are furious at Mei's attitude, and they carry out a gang rape of her in revenge. "W-what are you doing!?" She is half crying as she is surrounded by numerous penises. They force their penises into her small mouth. They don her deep throating her even when she gags. They make her wear an extreme competitive swimsuit that is even sexier than naked, and destroy the pride and pussy of this 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 their virility 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...
