not gonna lie i be reading or playing some of the ntr things and I be thinking the same and when I was thinking about this game I was wondering if that could happen but because it's a long distant relationship thing it'd be hard to do (maybe not impossible) so the best I can do currently is you taking control of how she does those things, know what I mean? I am open to suggestions tho!
Im not complaining, im sure this is going to be a great NTR game. You seem excited about it and have a great energy in the comments.
I think im just tired of the NTR genre as a whole - mainly because of the boring cliches that seem to exist in 99% of the genre.
If i was to give any pointers, it would be to give the villain/the bull a face - dont make him a typical faceless, personality-less, antagonist. Make him human, give him some character - it will make the hate the player feels for him more intense.
Same with the protagonist - dont make him a blank self-insert, give him a personality. Giving the MC a personality makes most readers empathise with the MC, which in turn, leads to more painful and better NTR.
The female lead too. Make her valuable. Give her a personality that makes her truly special to the MC - Make her someone who the player wants to fight for - that way the NTR hits so much harder when the cuck loses her.
I think the NTR stories that accomplish these things are always 'God Tier'.
