I admit, the story was pretty cliche to some extent, but there were 2 elements that I personally thought were unique and jumped out at me. One was the bad influence friend pushing the lead female to cheat. The fact that the MC didn't even have a long time friend in his corner was a bit gut wrenching. The second was the trip when the wife went to the beach with the bull-- how it was told from the husband's perspective first. Having the wife act cold and distant toward him when he called, overhearing the conversation in the mini-mart, and the way the wife was dressed different when he arrived to finally join her. Maybe I'm still new enough to this genre that that's nothing special, but for me, the most exciting and alluring elements are the ones that are implied, rather than outright shown. My mind can torture me by filling in the blanks, far better than just outright seeing the act of betrayal.
I get you, though they get pretty on the nose when they show the trip from her pov. It might hit you harder since you're new to it, but it falls flat to me. I've been polyamorous for well over a decade, so for me, having multiple partners, many of whom have other partners of their own is nothing new to me, so the notion of my partner fucking someone else is rather normal, same for me fucking other people too. But beyond that, My last monogamous relationship before I went poly ended with me busting my ex cheating on me, (in a twist of irony, my first polycule included my ex's girlfriend, whom also dumped her), So I know first hand what it feels like to be cheated on & I'm also an avid reader & writer, so I'm very particular about stories, especially from a functional nuts & bolts angle.
In my opinion, NTR is a genre that shouldn't exist. CALM DOWN CUCK BOYS, LEMME FINISH. I'm not shaming NTR itself, I'm saying it, in & of itself, should not be a genre. In story crafting, it's a plot element that people WAAAY too into it have tried to turn into a genre. It can add a lot to a story when implemented & used well, especially if it results in various outcomes both negative & positive for both parties. I hate to say it, but Lessons of Passion seem to have utilized it best in their games, as it's not used as a main focal point in most of the games they use it in, & the end result can range from the betrayal causing the protag to suffer & fall apart in a bad ending, or it can backfire on the cheating partner & she ends up suffering for it.
Think of the story like a steak. NTR as well as other fetishes, (i.e. incest, interacial, BDSM, etc...) would be like the seasoning blend & cooking oil used to cook it up in the pan, (olive, grapeseed or coconut for me please). Trying to make a story where it's all focused on NTR, (or any other specific kink for that matter), is like trying to cook salt in some oil & calling it a meal. No, it's unpalatable shit. & the end result is self evident. Cliche, 2 dimensional character tropes, formulaic paint by numbers plots that all follow the same points to the same end. It's boring. One of my partners was binging Criminal Minds over the past few days. The episode starts with some random person that's suddenly murdered, the BAU team gets the report, get's briefed at their home office, on to their jet to go to the location. Time to talk with local law enforcement & ask some questions to the people associated with the victim, they connect a few dots, time to release the profile they've compiled. they investigate more, dig, dig, dig, feed some clues to computer girl back at home office, she narrows it down to the suspect, gives them the suspects address, they bust into the place but oh no, the suspect isn't there, but they find a clue that tells them where the suspect is, They rush there & catch the guy in the act right in the nick of time, the end. You've just read the transcript of EVERY SINGLE FUCKING EPISODE of that piece of shit show. Interesting on episode 1, a rerun on 2, & why the fuck are they still making this by episode 3 & we're not even halfway through the first of 10 or 20 or 3000 seasons.
Sorry, I went on a rant again. My point is, NTR, like a good seasoning, can be a very good thing to add to a story when used sparingly & in a way to compliment the story as a whole. When it's turned into the main dish though, you get an oily pile of salt that only sycophants that love choking down salt would enjoy, as everything else that makes it potable, let alone good &7 enjoyable are either lacking or completely absent.
