In games like Sarah's Life, her husband gets cucked and you, the player, are pretty much her dom owner that deliberately looks to get her into situations where she is treated like a sex object, you are cucking her husband and corrupting her/treating her like a bimbo sexobject.
In something like Big Brother, you can either get cucked by the mothers boyfriend (when he starts screwing all your woman and treatens to send you of to the military) or by your sisters lesbian friend or if you get rid of him and don't let the lesbo thing play out, you trick your eldest sister to be your fuckthing thinking it's for the cam show, turn your mom into a sex object by getting her into porn and your little sister you actually start dating (unless you take the school friend route where you are somewhat cucked, but not really in the end).
Most of these games are a mix, between cucking, getting cucked and being a dom. Most games where the PC is the girl you get into situations, you are the owner, in games where you are the male PC and are forced to watch others fuck your appointed wife/girlfriend, you are a cuck and in games where you are the male PC and deliberately choose to get your wife/girlfriend into situations having sex with others or for non romantic reasons, you are also the owner (Big Brother has elements of this, with the mom and older sisters, but I don't know of any games other then maybe SimBro that who's primary focus is on that, while in that game the developers are cucking the shit out of their playerbase by not moving the story with the redhead further).
It's not a black and white playing field, most games mix dom, cuck and cucker roles, where most people likely look at cucker or dom roles to be the win states and being cucked the loss state.
