I've enjoyed College of Mysteria through and through, and through - but that's in part because it's not a game focused on the cuckquean fetish itself. It's just a trait of Cindy's, albeit not an optional one, and the game is much more than that. I still haven't found a scene where sharing Cindy disappointed me. Last update was gold.
But what I mean is that, while harem is implied in cuckquean "antics", I think good cuckquean and plain harem stories feel different, based on how part of the agency is shifted to the FMC. In CoM, Will could well be a loser like in so many NTS games out there, but Cindy empowers him, till later in the story he's completely over his initial aloofness. That's top character progression among all the games I've played. You CAN make the other girls exclusive to Will (bloody waste if you do) like in a pure harem game, but it's entirely up to the player. It's just a very well written game, at least if you share Cindy it doesn't feel like harem or free pass, ever. There's no crystallization on archetypes or "generally accepted parameters" for fetishes.
My only chagrin is that Steve did cave in to the anti-NTR hysteria and made the gloryhole scene with Cindy and other guys entirely dependent on the player encouraging her to do it, on a later version. When it first came out, it was Cindy's own initiative and took Will by surprise, he loved it anyways, it was truly great. The rabble will never understand true genius
