Due to her husband's transfer, the Princessaki couple started living in Tokyo. Since she was raised in the countryside, Hana, the wife, doesn't know how to be suspicious of others and has a lax sense of caution. She wraps her sweaty body in just a tank top while doing housework when the neighbor's husband happens to visit for a greeting. She exposes breasts that make one want to sink their teeth into them, and the man who loves large breasts tries to get closer by being overly helpful. Falling for his scheme, the innocent wife's ultimate body is devoured.
