A couple exchange trip held in Gunma Prefecture. A video of the whole story has arrived from a man who is holding a tour with a married couple on a bulletin board! The couples, who are all participating for the first time, are nervous and face each other on the bus! As time passed, the wives who were confused also had stranger stick SEX regardless of their husbands! Unsatisfied with open-air bath orgy, a big orgy with a couple at a banquet hall! !
