In the end, I decided to give
Big Black Diamonds a try. I don’t like the IR theme, but I’m weak to photorealistic AI art

On my first playthrough, I didn’t get any sex content because I avoided all the cuck and NTR choices. That proves a vanilla path is possible, at least.
Then I tried picking all the “horned” choices, and it was mostly NTS with mild NTR vibes. Sometimes there are hints of cheating, but it’s never 100% confirmed—maybe there was no cheating after all. I usually find the vibe in cuck BBC games disgusting, but I didn’t feel that here. The guys are mostly respectful, and the wife stays loving and respectful toward the MC. The MC himself isn’t a wimpy, whiny cuck.
The game does have the usual themes: small-penis humiliation (very mild, though), BBC sexual superiority, and maledom by BBCs—but all of it is toned down and much less offensive than in other games of this type. The game also gives you choices over what content you want to see. Plus, it’s surprisingly well written for a phone game.
So, as someone who generally hates BBC cuck games, I’d say give it a try—you might find it passable. What really helps is that there’s no drama or angst; everything is pretty light-hearted. There are no truly annoying characters—maybe except the boss, but he isn’t black and he’s nowhere near as bad as some others (not even close to the boss from
Whispers of Desire). There are no annoying “professional bulls” either.
Overall, it feels more like a sharing game than a cuckold game, as long as you make the right choices. That said, there are still some cuck vibes and all bulls are BBC (yet, at least), so be warned.
EDIT: played a bit further after picking all the "horned" choices in the beginning. Well at certain point the game starts throwing content at you w/o the player's approval, but the MC approves. I guess I made too much horned choices in the beginning. Well, pity, this is a sudden break in the pacing tbh. Before that it was just touching and nothing more, then suddenly during the day 2 she initiates an MMF threesome where she sucks dicks, gets vaginal and anal penetration. This feels really rushed and no choices makes it even worse. And the MC automatically agrees to all that. So no, I don't recommend it anymore. At least before we get a playthrough to know how to keep the "horned" points at the desired level.
2nd EDIT: Finished the horned path. Turned out she did cheat and not once. Something she confessed herself. Something you learn from another person. But yeah, the game started out okay but leaned into a cuckold game eventually, where wife sleeps with other men without your consent and did it in the past too.
I guess the moral here is that all bbc games end up like that, no exception
