wife can do whatever she want but husband can´t, how isn't that cucklod?
agreed.. that does represent the basic premise of the cuck fetish.. then again, context would matter, and even the cuck scene has a bunch of variations...different things for different times, I guess.
been a while since I last played this, probably a few updates behind, but I seem to remember that this couple had serious lack of communication... which ironically also makes most cuck situations in real life either a pipe dream or crumble under pressure.
if he does sleep with others behind her back and she doesn't know about it, that's something that happens outside the scope of the cuck dynamic.. but doesn't negate it per se... he's a cheater and a cuck.
if on the other hand she's aware that he does that, then that sort of disqualifies him from being a cuck.. at most he's someone who occasionally is submissive to his hotwife.
