I'd say that's a result of lazy writing more then anything. Pretty much every NTR/cheating/corruption/sharing/swinging/etc game ends up falling victim to this. They may start off pretty reasonable or realistic but they all quickly devolve into the woman becoming a giga slut who bangs anything that can fit into their holes.
what is wrong in being a giga-slut in a porn game?
obviously there are exaggerations because in all movies or visual arts there are unrealistic exaggerations...
you've seen the Avengers
you think you would like to watch a realistic superhero movie... where to lift a car they have to take the jack from the trunk
Even if it's supposed to be a sharing or swinging game, the dev can't be bothered to stick to the premise and it eventually becomes straight NTR whore cuckold.
understand you're one of those who doesn't like NTR and yet in real life if you've had more than one girlfriend you've definitely left her because she was cheating
betrayal is the most common thing when you are in relationship with a woman/man... and unless you kill all the women who cheat on you, the reality is this... there are many feminicides in the real world in fact.. (sigh)
jealousy is realistic... everyone feels it... but only those who control it live happily and free from the torment it causes
this game is about a couple who managed to overcome jealousy... because loving a woman/man means seeing her/him happy... and if they are happy... everything is fine!
He is happy watching her fucked by strangers
She is happy when her husband watch her fucked in all her holes...
Is this unrealistic?... I really don't think so!
there is an exaggeration to make the story spectacular with porn special effects in gangbang exactly like in the avengers movies there are AI special effects....
Anne could win the sex Olympics games and remain happily married to her husband... because her husband is the (world champion of no-jealousy and is the perfect husband for Anne he is the only one who has defeated jealousy.
the MC is the winner only if he manages to don't divorce!
This couple is perfect matched... Anne will never love another man if the player makes the correct choices!
BUT SHE FUCKS EVERY COCK SHE MEETS BECAUSE THAT IS WHAT HER HUSBAND ASKS HER TO DO

NO DRAMA FOR THIS COUPLE!
THE ONLY DRAMA IS IF THEY BREAK UP!
Anna's exciting adventure, Project Myriam, Angelica's temptation, Inside Jennifer, Jessica O Neal Hard News, Lily of the Valley, Lisa, The Office Wife, The office, Because I love her, etc etc etc to infinity.
this game will never be similar to other games
this Adventurous Couple, after 5 years of faithful marriage, decided to defeat the jealousy that would have made them divorce.
