DandaNa above words are my thoughts exactly.
Now to answer why i like it? is because women getting pregnant by the man she loves is a beautiful thing,
and if the women(she loves other guy) got pregnant by the man who is not her husband, that is disgusting, and since this is an ntr game, "pregnancy" can also mean that, the women scrapping out whatever values/morals/etc.. she got from her husband(like love, loyalty, respect, her husband's seed, etcetc),
And replacing with the values/morals/immorality of other men.
And i think, this creates a feeling of disgust/betrayal in husband and other 3rd party person like us.
And this is the element various Artist and (maybe the man who fucks someones wife or girl) try to create.
Tell me what you guys think.
