Watching Kenji fawn over Eiko's ass, Hideki wants to behave that way too, but also wants to set an example as the older brother, so he stops himself... Then one day, Kenji accidentally sees his mother masturbating with a dildo, as part of her daily routine to keep her ass in shape. Seeing his mother's big ass exposed in front of his face, Kenji explodes with ass-love, and begins to move towards Eiko...
