London, May 3 : Dungeon dad Josef Fritzl stopped having sex with his wife years ago, claiming "she is too fat for me," his sister-in-law claimed on May 2.
Josef's 56-year-old sister-in-law, Christine said that the 73-year-old electrical engineer pretended to wife, Rosemarie, 68, that he was working around the clock on the blueprints for machines he was building.
"He would go to the cellar every day at nine in the morning and he would often even spend the night there. He claimed he was drawing blueprints for the machines he was selling. Rosie was not even allowed to bring him a cup of coffee," The Sun quoted Christine, as saying.
"Everyone knew they stopped having sex since many years. He would say: 'My wife is too fat for me'. He was always running down Rosemarie and everyone noticed how he was always laughing the loudest at dirty sex jokes," she added.
And she told how Fritzl ruled the family home in Amstetten like a tyrant.
Christine said: "He behaved like a drill instructor with his children.
"They had to stop whatever they were doing and stand still when he would enter the room, even if they were in the middle of playing some game. They constantly feared punishment.
"The only way to escape that surrounding was to get married. And they all did that, as soon as they were old enough. When Rosemarie married Josef she was only 17. She never learned a trade and was at his mercy and he exploited that fact for 51 years."
Josef has seven children with Rosemarie and also fathered six kids with his own daughter, Elisabeth, now 42.
