A husband-wife swap tour being held in Gunma Prefecture. A video documenting the entire event was received from a man who organized a tour by gathering couples on a bulletin board! Couples, all first-timers, nervously meet inside the bus! Wives who were initially confused start having sex with others without caring about their husbands as time passes! Not satisfied with the outdoor hot spring orgy, they engage in a massive swap-orgy at the banquet hall!!
