Husbands who want to sleep and wives who accept their desires.People who seek new stimulation are drowning in extraordinary excitement.Yamamoto and Sonoda, who work at a video production company, became interested in 'swapping' that they heard at work and proposed it to their wives while traveling.The husbands who returned to the inn take advantage of the wives' good appearance and bring each other's wives to their rooms and stack their bodies.After that, the couple who tasted pleasure many times became a prisoner of pleasure that they had never known before.The banquet of the sake pond meat forest that takes place in a strange space far from everyday life drives the two couples crazy.
