Under the pretext of testing his wife's loyalty, a challenge begins with the husband sleeping right beside her. Confident that his wife would never betray him, he puts her to the test—how much temptation can she really resist? During a trip at a hotel, a masseuse is called to their room. With the husband asleep, the masseuse gradually begins touching the wife's body. Soon, she starts stimulating the wife's groin, going deeper as emotions rise. The wife forgets her husband's presence and eventually turns her gaze toward the man's penis. The impulses, emotions, and ultimate climax she experiences form the core appeal of this work.
