In a mixed-gender hot spring, there lurks a predator silently waiting for the opposite sex to arrive—this is the crocodile. Normally, it's men who play this role, eagerly anticipating naked women, but this time, it's married women taking on the role. Seeking relief from sexual frustration, housewives like Mary Tachibana and Akari Niimura head to a secluded mixed bath. As they patiently wait for their prey, a young man suddenly appears. At the sight of his huge, virile cock, the two aggressive women instantly switch on. Thus begins a two-day, one-night sex-filled hot spring getaway, where big-titted housewives turn the tables in a harem-style gangbang.
