[Femdom (possibly extreme), dominant abusive mature women)
You are a single male, alone, no near relatives, then you inherited a large house from a very distantly related old lady. The condition is that the housekeeper named Doris is allowed to continue her work and to life in the house permanently. You have just arrived at this house with your two suitcases to move in.
You do not know that Housekeeper Doris is a very special person with her own agenda.
