Patriarch - Version 0.6 by Oranos

Patriarch is an ambitious sandbox harem-builder game set in a dark near future where a single powerful crime family has brought a city to it's knees. You play as the heir to this family, whose job it is to make a name for himself and establish the connections necessary to lead an empire. Date and control the women near you, as you build a harem of girlfriends, wives and sex slaves.

The game features humiliation/degradation, rough sex and similar fetisches, all stemming from the idea of total power exchange. Not for the faint of heart!
