A couple swapping trip held in Gunma Prefecture. A video of the whole thing was sent to us by a man who was organizing a tour by gathering couples on a message board! All of the couples were participating for the first time, and they were nervous as they met on the bus! As time passed, the bewildered wives started to have sex with other men, regardless of their husbands! Not satisfied with the open-air bath orgy, they went to the banquet hall for a huge orgy of couples swapping!
