A successful husband enjoys a seemingly perfect marriage and looks after his cynical, sexually inexperienced adult junior Yoshino at work. Hoping to show him what married happiness feels like, he invites Yoshino home for dinner and drunkenly proposes that the man enjoy a pretend-couple experience with his wife Akahana while he leaves them alone. After three hours of nonstop sex and sixteen relentless creampies, the relationship between all three changes, and the husband realizes his wife has been taken from him.
