Daisuke and Masaya have been close friends since forever. Recently, these two have been fighting at school all the time. A teacher intervened to stop their fights and called their mothers to school. The reason for their fights was that "both of their mothers' asses are too attractive." On top of that, both of them are in the middle of their rebellious phase. Desperate, the mothers decided to use this overly attractive "ass" as a weapon to reconcile their sons and even correct their rebellious behavior!
