Two women living in the same apartment can share a submissive male or slave. The submale’s time is of little value. He has nothing better to do than clean up after his Dommes, cook their meals and meet each woman’s slightest wish.
If the women work different shifts the submale may have little sleep.
The two Dommes will enjoy collaborating in the submale’s punishment and discipline. Each will egg on the other to harsher strokes of the whip and belt.
The submale should be doubly grateful for being allow to be the servant of two female superiors.
