After a friend's wedding reception, the bride's friend Yuri Oshikawa invites a married man out for drinks. They click as fellow married adults and talk until the last train is gone, then use her drunkenness and the taxi fare as excuses to check into a nearby hotel together. The frustrated, big-titted wife throws herself into their double affair and takes multiple creampies. They keep fucking until checkout the next morning, leaving him wondering what he can possibly tell his wife.
