Momo and Tsukushi, full of curiosity, go out on an adventure into an abandoned factory when they hear the rumor that ghosts may be haunting it.

At the same time, our hero, a part-time security officer, and his superior head out to the same factory to patrol it and keep an eye out for any illegal dumping of garbage.

The 2 girls and the lusty 2 men become trapped in a tight space in the factory, and the men violate them, and of course, cum inside them!
