The Story - update #1

Thanks to 'beutelwolf' sharing a magazine article from 1973 on the Vintage Erotica Forum (beware of explicit imagery and pop-ups), I'm able to correct an earlier statement regarding Ulrike's father being an actor.
According to said German article, Hermann Butz was a television show host and presenter.
Now we also know what he looked like, and to what extent he wanted his daughter back home and off drugs.
