The One in LOVE

In a distant or not so distant future, an unemployed teacher decides to venture into space to make enough money to save the life of his wife. While he's on a mission to extract minerals from a distant asteroid, the central computer of the spaceship alerts our spaceman that the three gynoid robots on board may have a malfunction and that they can enter at any time in what is called a state of "loss of vital extensions", or LOVE, for short. Of course you know that on stories of this kind things are never what they seemed to be.
