I base my assumptions on the game I played so far, and judging by that, I'm not very confident; out of the 5 possible outcomes, only one could go this way, but only if you haven't chosen the "I like it" option- so even this branch is probably more likely to go the "Everybody enjoys it" path; also because you only get there if you say you enjoy watching your wife getting fucked.
All the other paths are the usual "MC is the weaver of fate" approach, where happens whatever MC says he is into. If he doesn't enjoy watching his wife getting fucked, it won't happen and he interrupts Steph and the black dude.
As so often in these games, the player and the main char are considered one and the same, and the idea that I want to see the main char suffer without him (or her) enjoying it doesn't come to mind and isn't a playable path.
Especially in games with cuckolding, this would be welcomed probably not only by sadists like me, but also by the target audience of cucks who maybe don't want to have a say in what the bull does with their wives.
So, when it comes to storylines that start with Steph and black dude fucking: you could develop a dynamic between them that shifts the relationship between MC and Steph and the enjoyment comes from seeing this "fall from grace", this struggle for and loss of control and power and so on- there are so many more things than just fucking that define and can intrude into a relationship; and even the fucking can be improved, not necessarily by "harder scenes", but by all the power games and structures that surround it.
But of course, if only happens whatever MC says he's into and he agrees to, then we end up with another game of "choose your sex scenes" decisions instead of a "You decide for MC, but you don't decide what happens" approach with some more interesting story telling.
