A successful office worker has enjoyed an apparently perfect marriage with his wife, Reii, for years. He also looks after Yoshino, a cynical and sexually inexperienced adult junior coworker. Hoping to show Yoshino the happiness of married life, he invites him home for dinner and, emboldened by alcohol, suggests letting him play house with his wife while the two are left alone. During those three hours, Yoshino keeps pounding her without pulling out and creampies her sixteen times. Afterward, both his wife and Yoshino begin acting strangely distant, leaving him to realize that his wife has been taken from him.
