Reika is a quiet, modest, and serious city employee. One day she visits the home of a stubborn single man who owes back taxes, but he refuses to pay even the late fees. Noticing the voluptuous body visible beneath her clothes, he makes a proposition: he will pay if she wears the outrageously tiny swimsuit he hands her. Reika is shocked and tries to resist, but her inability to say no when pressured puts her in a compromising situation.
