A mother named Kanako loves her son Kanta very much but finds him quite annoying at times. She tries to get his attention by inviting him out on a date, but he embarrassingly rejects her due to shyness. As if that wasn't enough, she discovers another shocking fact; Kanta had actually reserved a visit to a hostess club where he would have sex with a woman he didn't know. Unable to accept this idea, Kanako hatches a plan to arrive at the club before Kanta does and become his exclusive sexual companion herself...
