Ngl I find it a little incongruous with the storytelling that the MC lets the succubi basically rape him without even giving us the option of bitch slapping them back down.
He's apparently some sort of powerhouse. I can understand him not wanting to hurt his old friend, or her daughter. But surely there is a middle ground? At least he could threaten it. Or y'know, attempt to communicate healthily with them. Tell them 'hey, you know you just fucking raped me right? You're cool with that? You expect me to be cool with that?'
It's just weird when stories set up rape and then don't even acknowledge it as such. Like I want to be clear here, I have no issue with it's depiction and inclusion in a hentai, of course. I'm into it, even. But it's messing with my story immersion, you wrote the MC too well, I'm invested in him. So seeing him get his consent entirely ignored is something I can't just let go unaddressed. There's no good reason he should tolerate it. Especially since it's inherently creepier than your bog standard rape, all the date rape magic. In one scene he has strong opinions about it and the next he just lets it happens and doesn't mention it. And I don't really accept 'he likes it actually'. Even if it's true. That doesn't mean he'd just be fine with being raped.
Sorry to be a nag, I know you're probably just into this and are making a story for people who are too. And, superficially I *AM* into this too, to an extent. Also you're still early in, and who knows what your storytelling intentions are? I sure don't. But you had to go and write a neat character and now I want him to act like a person and not a hentai protagonist. I want to be clear that I appreciate your effort and don't actually want to backseat you, just vent my frustration really. It's not an uncommon one I have with these sorts of stories. Should've seen how heated I got at the end of Monster Girl Quest. The epilogue specifically.
I do need to work on the dynamic of things in terms of his response to what happens, I know. The issue is mostly me being unable to properly convey the personality I'm trying to establish for the MC. He doesn't freak out after because he didn't feel like he was in any
actual danger.
While I haven't had the time to fully show it yet, I've tried to make it somewhat clear via both his scars and the dialogue with Miraia in the prologue that he really doesn't care what happens to his body and is extremely muted emotionally. As such, as long as there's no lasting damage, he wouldn't particularly care what they did beyond the embarrassment of it. He definitely doesn't 'like it actually' in the way you're talking about, because I hate those hand-waves as well.
To add to that, he's from a time where what they're doing is perfectly normal. It's only because of his relationship with Miraia and by extension Runa that he isn't fighting back in any meaningful way. If a succubus he didn't know tried that on him, it would end poorly for them.
Having said all that, while
he doesn't have any strong opinions on what happened, that doesn't mean
others won't when they find out what happened. While Miraia and Runa don't see any issues as long as everyone involved felt good, other people won't take kindly to them using magic to rape their new ally/friend in Bastions case, while other characters who know him better will react
very negatively when they find out.
There will be times later on when he doesn't just let these things happen, specifically when it's someone he has no connection to or when they intend it maliciously; I know it's ironic that I'm saying him being jumped by two succubi isn't malicious, but it
is a hentai game, so some liberties can be taken.
As for it being creepy with all the magic, that's intentional to a degree, but I have been concerned I've been leaning too hard into it. The point of it is to show that succubi are terrifying because how strong you are doesn't matter once they reach a certain level, but I probably overdid it.
If you could tell me which scene it is you were describing specifically I'd appreciate it so I can go back and look at it again to see exactly what you meant.
Ironically enough, I also got heated at the epilogue of Monster Girl Quest and how it was handled.
I'm always open to feedback and I'm glad that you're invested in Nathan as a character, I was hoping people would feel that way before I get further into the story, as in my opinion it's not a good story if the MC is just bland and unlikable unless you're trying to use that specifically to contrast things.
To close this long comment, I'm aware that his reactions don't line up with how people who don't have all the info I do feel he should react, but I'm not sure how to really convey said info in-game aside from continuing the story and adding the events I have planned where those issues are brought up by other characters since Nathan himself doesn't see the issue that is very clearly there. If you have any suggestions on how I could do that, feel free to message me, I'm always open to suggestions.
