If you played the Shadow of Desire update lately, you would understand that that recent update was terrible. No build up. No fleshing out. No pacing. Just a bunch of new characters added who no one cares about because they got no back story, jump to groping, ball sucking and ball hopping. It became messy. Almost as if nothing matters anymore. What was impactful in the last chapter just gone. There is no point in reading. Sure some people like this quick to sex so they can get to bust a nut quick, but for the reading, its just terrible pacing and not hot at all. Anyway this isn't about Shadow of Desire.I don't get that feeling at all from either of the games you mention. All the side characters in this game feel like appropriate additions to build a harem or show conquest.
And Adding a toxic NTR path in Arato is just adding a different slant to NTR. Kendo is more of the loving Dom, Arato is more the sadistic user. Different kinks for different people. Not everyone wants Daddy Kendo and not everyone wants Bratty Arato.
I do understand your feeling though, as that is 100% my issue with SAO right now. Kind of killed the game for me being cockblocked to deal with some character I give zero fucks over.
I just don't see it here, but to each their own.
Here... Mary jumped on Arato nuts too quick. She has to build up with Kendo up to chapter 3 to start hoping his nuts. Her corruption took place and then by chapter 5 it full on love and commitment willing to do things for Kendo even if it means having sex with others. Where Arato comes in at chapter 3, its straight action and balls deep in with very little build up within 1 chapter? Bruh? Because of drug? Partner swinging? Sex frustration? Blackmail? Isn't she already kind of in love with Kendo? So she gonna cuck the guy who cuck the guy she cheated on? What? That is just I don't know? Terrible writing. No pace. No build up
It becomes like other NTR games I dislike. Now you got three partners, the MC, and the two antagonist while those two antagonist are also banging each others harems and the main. I am not fan of multiple different partners with no substances. Who do I pay attention to? Maybe once the main girl is corrupted. used and reach the peak of corruption then it makes sense for her to go around give herself up. I Just like build up and consistency. Otherwise what is the point in reading the story. I liked the the beginning to mid of King of Summers because it was grounded. But as new character came, just like SOD, things dragged out. Messy.
