Katie loved her little brother, and wanted nothing more than for him to be happy.
That was why when she caught him playing with his dick one night, instead of getting mad, she smiled and hugged him before giving him a talk. She reassured him that what he was doing was perfectly normal and healthy and nothing to be ashamed of.
Then she guided him to his bed to give him a more "hands on" lesson in sexuality.
