(1) The CEO and his wife are waiting for their subordinate and his wife at their home. As soon as they welcome them in, they get straight to the point. "Ise-kun...would you like to have sex with my wife? However, I won't be participating." "President, what is that...?" The CEO proposes wife swapping...but his wife will be with another man?! (2) Four middle-aged men and women gather in one room. The goal is to swap partners, but the Endo couple, who have responded to their call, and the wife in particular, prefers group play. With the addition of one male participant alone, the sexual feast begins again today!
