Sometimes to save a marriage from divorce extreme measures must be taken. For Michael and his wife that was the case, from wife to slave from husband to Master. He was happier than ever and she learnt to love her new role in His life.

Following how they save their marriage and get a new lease on life and Master and slave as they realise they've never been closer since their dynamic changed, improved. Their love was never stronger than it was a D/s.
