This one was hilarious! "Would you like to have sex?" made a great repeating punchline, and she is so distracted by the most excellent sex that she doesn't even notice for most of the story that he's clearing just doing it to distract her from the topic at hand.
The resolution was so easy, simply using a different kind of oil, that it might've been a little dissatisfying if the rest of the story wasn't so darned entertaining.
Despite the obvious pleasure provided by the bots, I'm not sure I'd really see them as a positive influence. It makes perfect sense, of course, instant gratification tends to sell well, but the end result is people sitting at home by themselves and masturbating a dozen times a day and not doing much else--yes, I'd call that masturbation, it is just using a very technologically advanced sex toy. But it wasn't out of character, and it was very entertaining, so this is just speculation, not gripes.
