Swinging isnt cuckoldry. Why is it that so many insecure people cant get that through their heads. Its insane. Hell, Stag/vixen sharing isnt even cuckoldry.
NTR is not Cuck. NTR is a mix of many things. And Netori, as this game has, is part of NTR. While Netori and Netorare is cuckoldry, Netorare is most often not. But they all fall under NTR.
However, as
ramvivat also points out, this game very much has cuckoldry in it, just not against the MC. So while i understand your message, its just wrong on more levels than one.
