Honestly, this would've been much much better without the rape scene. Not only is it morally reprehensible, it also ruins what would otherwise be a great doujin. I'm gonna be honest, I liked every scene except that one, and some of the later once get a bit tainted by it. Still I enjoyed seeing Sakiko reciprocate Hatsune's love in the scene in the house on the island. And also - yummy, NyaMutsu crumbs. (I need some NyaMutsuMortis doujins and/or fanfics. Plsss)
We share pretty much the same thoughts I believe. There were parts of the doujin that are enjoyable, but the drugging and assault was deeply unfortunate and uncomfortable all around. Also yes more Nya/MutsuMrtoris works would be nice.
I know people have lines that they draw and I do respect that, but really I think if you're out there shipping aunt/niece incest you're probably going to have to accept that everyone who is making content for this ship loves being problematic
I think you're conflating things. This is the only work of this ship on Dynasty that's rape as far as I can see, and there's been rape works of Bang Dream ships that aren't incest.
