The Johnson family decided they would become nudists at home. Susan's Dad kept getting huge erections every time he saw his naked daughter and told his wife maybe it was a bad idea to become nudists.
"Bill" she told him "It's only natural you get hard when you look at Susan, she ha a fine ass and beautiful firm tits. You should jerk off while you look at her to get it out of your system, I know she'll take it as a compliment!"
So Bill started jerking off whenever he looked at his naked daughter, that was until she offered to do it for him!
