Wataru, my son, had a secret 'kink' that he couldn't tell anyone else. When his father was away on business and the house was empty, he would peek at his mother taking a bath. One time, as Wataru was peeking as usual, his mother called out to him, 'Why don't you join me?' That was the beginning of the mistake. And from that day forward, the bathroom became a forbidden place for the parent and child.
