Pornomovie and Book name

[MacConnor]

Hi,

I´m looking for a book name
here´s what I have...
it´s a train ride in an old shaking train - I think in Japan, or a bathtub - it´s a erotic situation and the man inserts a gun with fake bullets in the womans clit, shoot´s and she comes
Does anybody have a clue ?

And I also look for a porno movie - displaid in Germany on TV, mid 90th, it was displaied after the "Liebe Sünde" show
woman the magic sticks to erect the men´s dicks
Sorry that all I got so far.
Does anybody have a clue ?

THX for any help
