Son Kusata notices that her mother-in-law, Kaho, is hiding in the bathroom and masturbating. Although I thought it was a bad thing, my hobby was to take a sneak peek after seeing Kaho taking a bath. One day, when Kaho asked me to help clean the bath and cleaned it together, I inadvertently sprinkled shower water on Kaho's body and got her clothes soaked. Kusata is irresistibly excited and attacks the abundant breasts that are unpleasantly transparent.
