'Azusa', who started living with her daughter and her husband, gradually increased the time spent with her son-in-law because both her husband and daughter were busy. One day, when the two of them went out to drink, Azusa was attacked by her son-in-law, and after that, the son-in-law began to aim for Azusa's big breasts everywhere. At first, Azusa resisted, but eventually it turned into an irreplaceable stimulus.
