You said that and then proceed to say that she will have lesbians scenes/relationships/sex without the MC needing to be there or with him being there, so color me confused. Are women not someone else than the MC? Or are we using the bad trope of women having sex with another women without their partner there can't be considered cheating/NTR/etc ?
Because I'm pretty sure that if insted of she having a lesbian sex scene it would be with a guy and you will say it's cheating, but because it is a lesbian scene it's ok right?
I just wanted to point out that if you say that no one is going to fuck Emma or the girls the MC is invested in, then that no one should include other girls as well, because a woman can cheat on you with another woman, it is the same when it comes to NTR/cheating, it doesn't mather the sex of the person she is fucking, it is the same action and should be treated the same way, let's stop with the porn tropes of every girl is bisex and every guy should be ok that the girls that accept to be with him and share him are fucking each other, instead of just be with the guy/galg that they decide to share, or at least let's put options for how to react to that.
