Tsubasa and Masaya, a beautiful couple. One day, a construction worker who is doing road construction in front of his house comes to ask if he can borrow a toilet. Her fastidious Masaya refuses, but she is forced to go up to the house and moreover, pee is scattered in her toilet. The next day, while Masaya is away, the workers come to visit her again and gang rape her furiously. At first, Tsubasa, who is obsessed with germs, disliked her so much that she felt nauseous, but gradually Tsubasa felt pleasure in being soiled.
