Toys & Masturbation

A lonely young woman is left the family farmhouse by her grandmother who always said, "I've got the trains to keep me company." This is a VERY mild story that will primarily appeal to those who are into machine self-stimulation or have a fetish about steampunk. There is no explicit sex.
