Two games come to mind that contain scenes where the MC is invited by a couple to be the bull in a cuckold scene.
One is Wife Trainer Files, where a side job has him join a couple at their home and fuck the wife, who does not humiliate her husband but asks you to let him suck you, a bit of a homoerotic push but the point doesn't seem to be that he's a closet gay, rather that he's a complete beta who will obey his wife to a fault (you can refuse with no repercussion). The other is Lust Theory, don't remember which season, where you meet an attractive woman and are later invited by her to leave the party, finding out only when you're in the car with her that she's married and that she and her husband would like for you to fuck her. The scene plays out where the husband is "sick" with jealousy and frustration, although he's dominant all the time, before, throughout and in the aftermath. The better you dominate his wife, the more he enjoys it but in the end, they see you out telling they might want to do it again with you, but you (as the MC) are left feeling like the objectified one in their fantasy.
Don't think LT is a sharing game for it, though, as this is one scene in a game designed to let you fuck every female across multiple attempts (resetting day trope), but
Wife Trainer Files might be worth mentioning. It has a swinging club where you can take any of your girfriends, and one of them can be a domme (if you train her so, and ask her to) who cucks you at home. Elsa's content can feel a bit extreme but it's controlled, you can play it like a one-time experience and then tell her to stop being a domme with you, or never let her domme you.
