That JAV

Miyu's big brother is really a drinking, peaceful pervert. He has a limp hand due to an injury, and he gets banged up just by asking Miyu to help him change his clothes, he washes his gym clothes with Miyu's body, he teaches Miyu to play the recorder and she can't stand it, he masturbates and won't let him cum, he teaches her swimming with an electric discharge, I don't understand any more!
